TECHNICAL FIELD OF THE INVENTION
The present invention relates to a 2-in-l cleansing and conditioning preparation that
renders excellent conditioning benefits. More particularly, the invention relates to a 2-in-l
cleansing and conditioning preparation containing non-exclusively silicone fluids and non-
silicon organic oil or fluid as intimate mixture present within a single droplet.
The invention in particular relates to 2-in-l cleansing and conditioning compositions
comprising of an intimate mixture of two or more oils. The invention further relates to the
preparation of the conditioning system comprising of a mixture of water insoluble non-volatile
silicon fluids and one or more water insoluble non-volatile non-silicon organic fluids. More
particularly the invention relates to 2-in-l cleansing and conditioning compositions comprising
intimate mixture of oils present within a single droplet.
BACKGROUND OF THE INVENTION
Conditioning compositions, which provide conditioning only, without cleansing
surfactants, are well known in the art. Such compositions are generally applied to the hair after
the cleansing composition has been rinsed away. However such compositions are not always
acceptable to consumers who prefer compositions, which cleanse and condition simultaneously.
Thus a continuous need has been felt for improved shampoo compositions that provide
combinations of cleansing and conditioning to the hair. Such compositions are also well known
in the art. These shampoos or shower-gel compositions typically comprise one or more
surfactants for shampooing or cleansing purposes and one or more conditioning agents. The
purpose of the conditioning agent is to make the hair easier to comb when wet and more
manageable when dry, e.g. less static and less fly-away. Typically, these conditioning agents are
water-insoluble oily materials, cationic polymers or cationic surfactants.

Amongst the most popular conditioning agents used in shampoo products are oily
materials such as mineral oils, naturally occurring oils such as triglycerides, organic oils and
silicone polymers. These are generally present in the shampoo as dispersed hydrophobic droplets
in the surfactant system. Conditioning is achieved by the oily material being deposited onto the
hair resulting in the formation of a film.
Silicone oil has been widely used as conditioning agents in cosmetic formulations. Use of
silicone in shampoo preparation makes the hair easier to comb and improves the manageability
of hair. However, repeated use of silicone oil causes excessive build up thus giving the hair oily
and non-clean feel.
WO 95/09599, published April 13, 1995, to Murray et al., discloses a shampoo
composition containing a cationic polymer deposited in soluble silicone oils, especially
Dimethiconol. These systems are most effective, e.g., provide uniform deposition of the
conditioning agents onto hair, when the silicone is emulsion polymerized and the average
particle size of the emulsion polymerized polymer is less than 2um, preferably less than 1 micron.
The disclosure is restricted to compositions containing polymers with particle size less than 2um.
Moreover the application did not teach the emulsion of silicone combined with
hydrocarbon/ester/organic oil together in single droplet. The drawback observed was being small
particle size; the deposition on hair was minimum as most of it is getting washed away during
rinsing.
One method to improve deposition of conditioning oils onto hair is to use large droplets
of oil. This method relies on physical contact between the hair and the droplets followed by the
oil droplet wetting the hair surface and spreading. However compositions comprising larger oil
droplets tend to give uncontrolled deposition of silicon oil on hair resulting in build up. These are
unstable and tend to settle down on long standing.

Indian patent application 0584/DEL/90 dated 14/06/1990 discloses, improved hair
conditioning shampoo comprising specific water soluble anionic detergent having one or more of
C6, C8 and C10 alkyl sulfate and C6, C8 and C10 alkylethoxy sulfate. And water insoluble hair
conditioning agent selected from group comprising of organosilicone compounds, polyethylene
paraffins, petrolatum, microcrystalline waxes, C18-C36 (mixed) fatty acids and mixed
triglycerides, stearyl stearate, bees wax, cationic quaternary ammonium salts and mixtures
thereof. Also long chain alkyl containing compound having 28-45 carbon atoms in the
hydrocarbon chain selected from the group consisting of an alcohol an ethoxylated alcohol an
acid or an ester or any mixtures thereof
WO 9818434, published May 07, 1998, to Woodrow et al., teaches shampoo
compositions which contain select emulsion polymerized silicone polymers which are derived
from the emulsion polymerization of linear dimethylpolysiloxane monomers. However, this
application does not teach the impregnation of silicone / organic / hydrocarbon oil by means of
emulsion polymerization method with respect to increase hair cleaning and conditioning benefits.
WO 0191706, published December 06, to Takashi et al., relates to hair conditioning
compositions comprising non-volatile/volatile silicone compounds, isoparaffin hydrocarbons,
polysiloxane resin. The disclosure was restricted to conditioning compositions and even so failed
to achieve shine benefit and other conditioning benefits such as softness, smoothness attainable
with silicones and oils put together in emulsion polymerized form.
WO 2007053424, published May 10, 2007 to Burn et al., provides silicone vesicle
compositions and emulsions containing silicone vesicles, the compositions prepared therefrom,
and formulated personal and healthcare products containing the silicone vesicles and emulsions
compositions • However, this application does not involve emulsion polymerization technique to
incorporate silicone, hydrocarbon/ester/organic oil to provide superior benefits to the hair and/or
skin.
US Patent 6,071,975, published June 6, 2000, to Halloran directed to thermodynamically
stable, clear, single phase, silicone oil-in-water microemulsions. However, this application does

teach the emulsion of silicone combined with hydrocarbon /ester / organic oil together to achieve
superior benefits related to hair cleansing and/or conditioning aspects.
US Publication 20050232892, published October 20, 2005, to Edward et al., discloses a
hair conditioning composition with a pH of 8 or less comprises:(a) 0.01% to 10% by weight of
one or more cationic surfactants; (b) 0.01% to 10% by weight of one or more fatty alcohols
having from 18 to 22 carbon atoms; (c) 0.001% to 5% by weight of a hydrophobically modified
clay; and (d) water wherein, the weight ratio of cationic surfactant to fatty alcohol is from 1:1 to
1:10. However, the emulsion of silicone in combination with hydrocarbon/ester/organic oil was
not imparted towards the conditioning benefits to hair.
Japanese Patent 7053340, published February 28, 1995, to Hisataka et al., provides a
shampoo composition includes silicone and isoparafin hydrocarbon. However, this patent failed
to teach the improved benefits on hair conditioning especially in a dried state.
Japanese Patent 8175968, published July 09, 1996, to Sutaachi, teaches a rinsing-type
skin conditioner composition to be used in showering and allowing a skin conditioning
ingredient to be left on the skin after applied on the wet human skin, comprising a hydrocarbon
oil, specific binary or ternary block copolymer and surfactant at specified proportions. However,
this patent failed to produce the appreciable effects over hair conditioning requirements.
Japanese publication 2000072628, published March 07, 2000, to Toshiaki, relates to a
hair-conditioning composition includes silicone derivatives and ester oil.
Japanese publication 2002370943, published December 24, to Toshiaki, teaches a hair
rinse composition including silicone emulsion and ester oil.
Japanese publication 2003095890, published April 03, 2003 to Makoto et al., discloses a
hair rinse composition includes silicone oil and ester oil however, does not provide any improved
benefits on hair glossiness, firmness, pliability and/or smoothness.

WO 03/075866, published September 18, 2003, to Mahadeshwar et al., teaches shampoo
compositions, which provides a combination of cleansing and conditioning to the hair by
utilizing functionalised silicone and a hydrocarbon oil. However, this application restricts its
disclosure to low viscosity, functionalized silicones and in particular excludes
dimethicon/dimethiconol. It prefers the use of lower viscosity functionalised silicones to high
viscosity ones. The amino-functional silicone are known to give build up on hair if used in
higher dosage. Interestingly various prior art discloses use of high viscosity silicones such as
Dimethicone/Dimethiconol to provide better conditioning. The publication further discloses an
emulsion, which is made by mechanical emulsification of silicones and oils and is present within
common droplet.
There exists a need for a shampoo preparation that reduces build up of silicone oil and
can be used on both oiled and non-oiled hair. The inventors of this invention found that when
specific silicon oils are used in combination with other organic oils such as Hydrocarbon and/or
ester oil, the preparation could be used for both oiled and non-oiled hair. It was seen that this
combination gave better conditioning, cleaner feel and reduced build up in both oiled and non-
oiled hair types with improved hair fullness and body. Also it was seen that incorporating
organic oils into high viscosity water insoluble organosilicone during the emulsification process
helped them overcome the stability problem of the preparation. It remains desirable therefore to
provide a hair care composition, which has improved, conditioning, is easy to manufacture, is
cost effective and has better storage efficacy.
OBJECTS OF THE INVENTION
The primary object of the invention is to formulate a 2-in-l cleansing and conditioning
preparation that renders excellent conditioning property along with high stability, reduced build
up, clean feel, hair fullness and body.
Further, it is the object of the invention to provide a 2-in-l cleansing and conditioning
composition comprising a intimate mixture of two or more oils present within a single droplet.

Furthermore it is the objective of the invention to provide a 2-in-l cleansing and
conditioning composition comprising oil(s) and suitable emulsifiers to stabilize the emulsion,
prepared by mechanical emulsification /emulsion polymerization of water insoluble non volatile
silicon fluids and water insoluble non volatile non silicon oils present within a single droplet.
A further object of the invention is to formulate a shampoo preparation ideal for
conditioning both oiled and non -oiled hair.

CATIONIC DEPOSITION POLYMER
A cationic deposition polymer is an essential ingredient in shampoo compositions of the
invention. By "deposition polymer" is meant an agent that enhances deposition of the silicone
component from the shampoo composition onto the intended site during use, i.e. the hair and/or
the scalp.
The deposition polymer may be a homopolymer or be formed from two or more types of
monomers. The molecular weight of the polymer will generally be between 5,000 and
10,000,000, typically at least 10 000 and preferably in the range 100,000 to about 2,000,000. The
polymers will have cationic nitrogen containing groups such as quaternary ammonium or
protonated amino groups, or a mixture thereof.
The cationic nitrogen-containing group will generally be present as a substituent on a
fraction of the total monomer units of the deposition polymer. Thus when the polymer is not a
homopolymer it can contain spacer non-cationic monomer units. Such polymers are described in
the CTFA Cosmetic Ingredient Directory, 3rd edition. The ratio of the cationic to non-cationic
monomer units is selected to give a polymer having a cationic charge density in the required
range.
Suitable cationic deposition polymers include, for example, copolymers of vinyl
monomers having cationic amine or quaternary ammonium functionalities with water soluble
spacer monomers such as (meth)acrylamide, alkyl and dialkyl (meth)acrylamides, alkyl

(meth)acrylate, vinyl caprolactone and vinyl pyrrolidine. The alkyl and dialkyl substituted
monomers preferably have C1-C7 alkyl groups, more preferably CI-3 alkyl groups. Other
suitable spacers include vinyl esters, vinyl alcohol, maleic anhydride, propylene glycol and
ethylene glycol.
The cationic amines can be primary, secondary or tertiary amines, depending upon the
particular species and the pH of the composition. In general secondary and tertiary amines,
especially tertiary, are preferred.
Amine substituted vinyl monomers and amines can be polymerized in the amine form
and then converted to ammonium by quaternization.
The cationic deposition polymers can comprise mixtures of monomer units derived from
amine- and/or quaternary ammonium-substituted monomer and/or compatible spacer monomers.
Suitable cationic deposition polymers include, for example: Polyquaternium 10,
Polyquaternium-16 and Polyquaternium-11; cationic diallyl quaternary ammonium-containing
polymers including, for example, dimethyldiallyammonium chloride homopolymer and
copolymers of acrylamide- and dimethyldiallylammonium chloride, referred to in the industry
(CTFA) as Polyquaternium 6 and Polyquaternium 7, respectively; mineral acid salts of amino-
alkyl esters of homo- and co-polymers of unsaturated carboxylic acids having from 3 to 5 carbon
atoms, (as described in U.S. Pat. No. 4,009,256); cationic polyacrylamides (as described in
W095/22311). Other cationic deposition polymers that can be used include cationic
polysaccharide polymers, such as cationic cellulose derivatives, cationic starch derivatives, and
cationic guar gum derivatives.
Cationic polysaccharide polymers suitable for use in compositions of the-invention
include those of the formula: wherein: A is an anhydroglucose residual group, such as a starch or
cellulose anhydroglucose residual. R is an alkylene, oxyalkylene, polyoxyalkylene, or
hydroxyalkylene group, or combination thereof. R.sup.l, R.sup.2 and R.sup.3 independently
represent alkyl, aryl, alkylaryl, arylalkyl, alkoxyalkyl, or alkoxyaryl groups, each group

containing up to about 18 carbon atoms. The total number of carbon atoms for each cationic
moiety (i.e., the sum of carbon atoms in R.sup.l, R.sup.2 and R.sup.3) is preferably about 20 or
less, and X is an anionic counterion.
Cationic cellulose is available from Amerchol Corp. (Edison, N.J., USA) in their Polymer
JR (trade mark) and LR (trade mark) series of polymers, as salts of hydroxyethyl cellulose
reacted with trimethyl ammonium substituted epoxide, referred to in the industry (CTFA) as
• Polyquaternium 10. Another type of cationic cellulose includes the polymeric quaternary
ammonium salts of hydroxyethyl cellulose reacted with lauryl dimethyl ammonium-substituted
epoxide, referred to in the industry (CTFA) as Polyquaternium 24. These materials are available
from Amerchol Corp. (Edison, N.J., USA) under the trade name Polymer LM-200.
Other suitable cationic polysaccharide polymers include quaternary nitrogen-containing
cellulose ethers (e.g. as described in U.S. Pat. No. 3,962,418), and copolymers of etherified
cellulose and starch (e.g. as described in U.S. Pat. No. 3,958,581).
A particularly suitable type of cationic polysaccharide polymer that can be used is a
cationic guar gum derivative, such as guar hydroxypropyltrimonium chloride (Commercially
available from Rhodia (formerly Rhone-Poulenc) in their JAGUAR trademark series).
Examples are JAGUAR C13S, which has a low degree of substitution of the cationic
groups and high viscosity. JAGUAR CI5, having a moderate degree of substitution and a low
viscosity, JAGUAR CI7 (high degree of substitution, high viscosity), JAGUAR CI6, which is a
hydroxypropylated cationic guar derivative containing a low level of substituent groups as well
as cationic quaternary ammonium groups, and JAGUAR 162 which is a high transparency,
medium viscosity guar having a low degree of substitution.
Preferably the cationic deposition polymer is selected from cationic cellulose and cationic
guar derivatives. Particularly preferred deposition polymers are JAGUAR C13S, JAGUAR CI5,
JAGUAR C17 and JAGUAR CI6 and JAGUAR CI62.

The cationic deposition polymer will generally be present at levels of from 0.001 to 5%,
preferably from about 0.01 to 1%, more preferably from about 0.02% to about 0.5% by weight
based on the total weight of the shampoo composition.
WATER INSOLUBLE HAIR CONDITIONING AGENT: /
The water insoluble, non volatile organosilicone fluid is present in the mixture droplets at
a level of at least 5 percent by weight, preferably at least 25 percent by weight, more preferably
at least 40 percent by weight and most preferably at least 50% by weight based on the total
weight of the mixture droplets.
Suitably, the water insoluble, non-volatile organosilicone fluid has a viscosity of 60,000 cst and above preferably more than 1,00,000 est, more preferably more than 2,00,000 cst 25°C.
NON SILICON ORGANIC FLUIDS / OILS y
Non silicone organic fluids/oil(s) used in this invention are selected from various
hydrocarbon oils and ester oils present in the prior art.
The ester oil herein are surface modifiers which provides conditioning benefits such as
moisturized feel, smooth feel, and manageability control to the hair when the hair is dried, yet
not leave the hair feeling greasy. It is believed that insoluble oily materials in general are capable
of being deposited on the hair. Without being bound by theory, it is believed that the ester oil
reduces hair friction to deliver smoothness and manageability control to the hair. It is also
believed that, because it has some hydrophilic groups, the ester oil provides moisturized feel.
The ester oil is chemically stable under normal use and storage conditions.
The ester oils useful herein are selected from the group consisting of alkyl and alkenyl
esters of fatty acids, alkyl or alkenyl esters of fatty alcohols, polyhydric alcohol esters,

dicarboxylic acid esters, tricarboxylic acid esters and mono-, di- and tri-glycerides and mixtures
thereof.
The ester oil is preferably included in the emulsion of conditioning oil composition at a
level by weight of from about 0.01% to about 25%.
The hydrocarbon oil is present in the emulsion of conditioning oil at a level of at of from
about 0.01% to about 50%.
Suitably, the hydrocarbon oil has a viscosity at 25°C of less than 500 mm2s-l, preferably
less than 300 mm2s-l, more preferably less than 200 mm2s-l and most preferably less than 50
mm2s-l.
Hydrocarbon oils include cyclic hydrocarbons, straight chain aliphatic hydrocarbons
(saturated or unsaturated), and branched chain aliphatic hydrocarbons (saturated or unsaturated).
The hydrocarbon oils will preferably contain from 12 to 60 carbon atoms. Also suitable are
polymeric hydrocarbons of alkenyl monomers, such as C2-C6 alkenyl monomers. These
polymers can be straight or branched chain polymers. The straight chain polymers will typically
be relatively short in length, having a total number of carbon atoms as described above for
straight chain hydrocarbons in general. The branched chain polymers can have substantially
higher chain length.
Specific examples of suitable hydrocarbon oils include paraffin oil, mineral oil, saturated
and unsaturated dodecane, saturated and unsaturated tridecane, saturated and unsaturated
tetradecane, saturated and unsaturated pentadecane, saturated and unsaturated hexadecane, and
mixtures thereof. Branched-chain isomers of these compounds, as well as of higher chain length
hydrocarbons, can also be used. Exemplary branched-chain isomers are highly branched
saturated or unsaturated alkanes, such as the permethyl-substituted isomers, e. g., the permethyl-
substituted isomers of hexadecane and eicosane, such as 2, 2,4, 4,6, 6,8, 8-dimethyl-10-
methylundecane and 2,2, 4, 4,6, 6-dimethyl-8-methylnonane, sold by Permethyl Corporation. A

further example of a hydrocarbon polymer is polybutene, such as the copolymer of isobutylene
and butene.
A commercially available material of this type is L-14 polybutene from Amoco Chemical
Co. (Chicago, 111., U. S. A.).
Particularly preferred hydrocarbon oils are the various grades of mineral oils. Mineral
oils are clear oily liquids obtained from petroleum oil, from which waxes have been removed,
and the more volatile fractions removed by distillation. The fraction distilling between 250°C to
300°C is termed mineral oil, and it consists of a mixture of hydrocarbons ranging from C16H34
to C21H44. Suitable commercially available materials of this type include Sirius M85 and Sirius
M45, available from Silkolene. (Trademark).
Another embodiment of the present invention, illustrated without limitation, in Figure 1,
provides a method (200) for incorporating discrete droplets comprising a water insoluble, non
volatile organosilicone fluid and an organic oil in the same droplets, into a hair treatment
composition. The method (200) of the present invention comprises the steps of; i) adding at least
one silicone fluid (210) to at least one non-silicone fluidV(oil) (220) to form an intimate, non-
aqueous blend (230); ii) adding water/emulsifier (240) to the aqueous blend (230) to prepare an
aqueous emulsion (250); and iii) incorporating said aqueous emulsion (250) in a hair care
composition (260) to form a two-in-one cleansing and conditioning composition (270). The
aqueous emulsion thus comprises water insoluble, non-volatile organosilicone fluid and non-
silicone fluid/oil within the same droplet. Preferred process for preparing aqueous emulsions of
the mixture droplet involves use of high shear mixer.
In another embodiment the invention discloses a composition comprising conditioning
oil, which constitutes water insoluble, non volatile organosilicone fluid and non-silicone organic
fluids/oil(s). Both organosilicone and non-silicone organic fluids/oil(s) have together been
known to provide desirable conditioning properties to hair treatment compositions such as
shampoos and conditioners. The conditioning oil incorporated in the composition provides both
the desirable constituents to the composition.

In another embodiment the invention discloses a composition wherein the quantity of oil
added to achieve required conditioning levels is appreciably reduced. Less of oil adds to the
clean feel achieved by the composition while giving optimum hair fullness and body.
In still another embodiment the invention discloses the use of silicone units exhibiting a
high kinematic viscosity for the preparation of conditioning oils. The use of highly viscous
silicones together with organic oils as a close intimate mix to improve the conditioning abilities
of hair care compositions has yet been unknown in the art. Even though it is known in the art that
silicones exhibiting high viscosity show better conditioning capabilities as compared to their low
viscous counterparts, methods for effectively using high viscosity silicones and silicone
polymers together with oils was not known. It was very surprisingly found by the scientists that
when organic oil was added to organosilicone during the process of emulsification via
mechanical or emulsion polymerization route then irrespective of the kinematic viscosity of the
constituent organosilicone, highly stable oil imbedded silicone polymers were formed. This
product demonstrated enhanced conditioning qualities as evident in Table 1.

The conditioning oil in formulations F and G were prepared by emulsion polymerisation route by
bringing together, dimethiconol, trimethylol propane tricaprylate/tricaprate and isohexadecane
such that each droplet of the emulsion would comprise the intimate mixture of these 3
ingredients so as to form highly stable oil imbedded silicone polymer.
(5) The above mixture of step (4) were mixed well. Preservative and perfume were added and
mixed well to obtain the final compositions.
Process for sensory Evaluation of A-G:
(1) Hair Tresses were cleaned with SLES, washed with water and dried with dryer and stored in
zip-lock bags.
(2) For sensory evaluation, each hair tress was wetted with water and the specific shampoo
formulation (2ml) was applied evenly on the hair tress and rubbed on the hair 10 times
(3) Treated hair tresses were washed with water and dried using hair drier
(4) Dried hair tresses were used for sensory evaluation.
The formulations were ranked on a scale of High> Moderately high> Moderate> Slightly
High> Low for the attributes of softness, silkiness and gloss. For the attributes of Ease of
detangling and force to comb, these were ranked as Easy/No force> Moderately difficult/Low.
The results as obtained are depicted herewith in Table 1.



It was found that the compositions comprising the novel conditioning oil showed
appreciable advancement in conditioning capabilities. The significant advancements could be
linked directly to the presence of conditioning oil incorporated therein.
