FIELD OF INVENTION
The present disclosure broadly relates to a personal cleanser composition. The present disclosure also discloses a cleansing composition comprising the thickener-free surfactant system. The present disclosure further discloses a process of preparing the thickener-free surfactant system.
BACKGROUND OF INVENTION
The primary function of human skin is to provide a barrier against germs, dirt, dust and pollutants with the help of lipids and proteins present in human skin. Therefore, cleansing of skin becomes important to remove dirt and germs from the skin. Conventionally, various types of products that are based on surfactants are used for cleansing the skin, body and face. The normal method of cleansing the skin uses foam-based cleansing products which are commercially available in form of face-wash, foaming bars, soaps, etc. However, the development of above-mentioned personal cleansing products that are able to provide a combination of desirable properties such as good foaming, good cleansing, enhanced mildness, improved skin-feel, and attractive product appearance without imposing any limitation has been a challenging task.
It is well known in the art that the cleansing products used for personal purposes are typically aqueous and comprise one or more mild detersive surfactants and/or soaps. Skin cleansing by using soaps based on alkali, interacts with skin proteins and natural skin oils, disrupting the protein-lipid-water balance of the skin. Consequently, soap-based products remove dirt and germs from the skin along with essential proteins and lipids causing dryness of the skin.
Similarly, personal cleansers based on synthetic detergents often impart poor skin feel during and after use and require additives to improve such tactile aspects of performance. Further, synthetic detergents often degrease the skin to an excessive degree thereby resulting in dry skin too.
Therefore, researchers have strived to develop a mild skin cleansing composition that uses anionic surfactants with non-sulfated head groups such as sarcosinates, sulfosuccinates, acyl glycinates, etc. Examples of developments in

providing a mild skin cleansing composition includes the following mentioned
documents.
[006] Examples of developments in synthetic personal cleansing formulations
include US Patent Application US4812253A that discloses an ultra-mild skin
cleansing composition comprising: mild synthetic surfactants, moisturizers,
polymeric skin mildness aids and selected levels of soap. Further, the ultra-mild
skin cleansing bar disclosed in the corresponding Patent Application is milder on
the skin than water.
[007] US Patent Application US4338211A discloses a liquid surfactant skin
cleanser with lather boosters, wherein said liquid surfactant cleanser comprising: an
anionic surfactant; a lather booster; and water
[008] U.S. Patent Application US5965500A describes liquid cleansing
compositions containing levels of oil/emollient equal to or greater than the level of
surfactant. The surfactant system contains at least one anionic surfactant, which
may be an aliphatic or aromatic sulfonate.
[009] The potential use of skin cleansing composition comprising surfactants that
require additional polymers or electrolyte as thickening agents impart a level of
viscosity to the composition.
[0010] In the recent years, mild anionics & amphoterics are being extensively used
to formulate skin cleansing. Anionic surfactants with non-sulfated head groups
such as sarcosinates, sulfosuccinates, acyl glycinates, alkyl ether carboxylates, etc.
are considered to be mild on skin but are expensive to formulate as the
formulations require additional thickening agents such as natural or synthetic
polymers at high dosage levels. These systems do not thicken with salt or betaines
unlike conventional SLES or ALES (ethoxylated) systems. Often identifying
thickening agents that work very well in the formulation at low use levels within
required pH range and cost targets for such systems becomes challenging.
[0011] Accordingly, there remains a need in the art for an effective thickener-free
cleansing composition that provides enhanced skin feel, low skin irritation, low
skin drying, good cleansing ability, good foaming, and good rinsability
characteristics/properties.

DETAILED DESCRIPTION OF THE INVENTION
[0018] Those skilled in the art will be aware that the present disclosure is subject to variations and modifications other than those specifically described. It is to be understood that the present disclosure includes all such variations and modifications. The disclosure also includes all such steps, features, compositions, and compounds referred to or indicated in this specification, individually or collectively, and any and all combinations of any or more of such steps or features. Definitions
[0019] For convenience, before further description of the present disclosure, certain terms employed in the specification, and examples are delineated here. These definitions should be read in the light of the remainder of the disclosure and understood as by a person of skill in the art. The terms used herein have the meanings recognized and known to those of skill in the art, however, for convenience and completeness, particular terms and their meanings are set forth below.
[0020] The articles "a", "an" and "the" are used to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article.

[0021] The terms "comprise" and "comprising" are used in the inclusive, open
sense, meaning that additional elements may be included. It is not intended to be
construed as "consists of only".
[0022] Throughout this specification, unless the context requires otherwise the
word "comprise", and variations such as "comprises" and "comprising", will be
understood to imply the inclusion of a stated element or step or group of element or
steps but not the exclusion of any other element or step or group of element or
steps.
[0023] The term "including" is used to mean "including but not limited to".
"Including" and "including but not limited to" are used interchangeably.
[0024] For the purpose of the present disclosure, the term "thickener-free
surfactant system" comprises a surfactant system which is devoid of any thickener.
The thickener-free surfactant system of the present disclosure comprises three
surfactants, i.e. primary surfactant, secondary surfactant and tertiary surfactant. The
term "thickener" refers to the polymers such as carbopol (acrylic acid/acrylate
polymers), natural gums like (guar gums) and poly ethoxylated non-ionic polymer
systems (polyethylene glycol (PEG) distearates, PEG-120 methyl glucose dioleate,
ceteareth-60 myristyl glycol, etc) or electrolyes (such as NaCl, KC1) which are
generally used to thicken the composition.
[0025] The term "primary surfactant" used herein in the present disclosure are
those which give excellent foam and lather characteristics in personal wash
cleansing formulation. They are usually added at concentrations higher than other
surfactants in the formulation. As used herein the primary surfactant is an anionic
surfactant.
[0026] The term "secondary surfactant" used herein in the present disclosure is
having lower cleansing properties, yet, they help to boost foam, and to reduce
irritation.
[0027] As used herein, the term "tertiary surfactant" stabilize foam of the
formulation. They also reduce negative interactions with skin proteins.
[0028] For the purpose of the present disclosure, weight percentage(s) that are
referred in the present disclosure, refers to the "active matter" of the surfactant

system. For instance, if 10 ml of 70% of disodium laureth sulfosuccinate is taken and further added to 90ml of X solution, the active matter of disodium laureth sulfosuccinate present in 100 ml X solution would be about 7%. Likewise, the weight percentages of all the components as disclosed in the present disclosure refers to their active matter percentages.
[0029] Ratios, concentrations, amounts, and other numerical data may be presented herein in a range format. It is to be understood that such range format is used merely for convenience and brevity and should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. [0030] Various skin cleansing composition deploying electrolytes in ionic surfactant system cause instability. Additionally, said ionic surfactant system penetrate the skin and interact with stratum corneum. The excessive use of said ionic surfactants that disrupts the stratum corneum lipid bilayer removing essential protein and lipids, cause skin dryness, irritation, redness etc. (Principles of polymer science and technology in cosmetics and personal care: e.d. goddard and j.v. gruber (eds.), m. dekker, newyork, 1999, 671 pages)
[0031] In the recent years, the development of surfactant-based cleansing composition deploying the use of mild anionics and amphoterics are becoming increasingly common. However, the use of said surfactant-based cleansing composition requires additional thickening agents such as natural or synthetic polymers at high desirable levels to provide desired viscosity. The use of additional thickening agents in said surfactant-based cleansing composition are found to be expensive to formulate said surfactant-based cleansing composition. [0032] Therefore, to overcome the afore-mentioned problems, the present disclosure provides a thickener-free surfactant system, wherein said thickener-free surfactant system comprising an anionic surfactant, non-ionic surfactant and amphoteric surfactant. The use of said thickener-free surfactant system can be further utilized in preparing a cleansing composition. The anionic surfactant, non-ionic surfactant and amphoteric surfactant that are used within fixed weight

percentages as disclosed in the present disclosure provides desired viscosity to said cleansing composition. Particularly, the desired viscosity can be achieved by self-assembly of said thickener-free surfactant system to achieve polymer-free thickening cleansing composition without affecting the formulation cost. Therefore, the thickening of thickener-free surfactant system was achieved without polymers (such as carbopols (acrylic acid/acrylate polymers), natural gums like (guar gums) and poly ethoxylated non-ionic polymer systems (peg distearates, peg-120 methyl glucose dioleate, ceteareth-60 myristyl glycol, etc) or electrolyes (such as NaCl, KC1).
[0033] The cleansing composition as disclosed in the present disclosure exhibits good cleansing ability, good foaming, and good rinsability characteristics/properties. Further, said cleansing composition do not leave the skin feeling tacky or tight during drying. Therefore, the cleansing composition as disclosed in the present disclosure may be applied on sensitive skin and dermatologically compromised skin conditions.
[0034] The cleansing compositions may be further utilized alone, as skin or body washes, or to produce various face cleansers, body washes, bath soaps, etc. [0035] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the disclosure, the preferred methods, and materials are now described.

EXAMPLES
[0067] The disclosure will now be illustrated with working examples, which is intended to illustrate the working of disclosure and not intended to take restrictively to imply any limitations on the scope of the present disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this disclosure belongs. Although methods and materials similar or equivalent to those described herein can be used in the practice of the disclosed methods and compositions, the exemplary methods, devices and materials are described herein. It is to be understood that this disclosure is not limited to particular methods, and experimental conditions described, as such methods and conditions may apply. [0068] The working and non-working examples as depicted in the forthcoming sections highlight the criticality of the working percentages of different surfactants in achieving the thickener-free surfactant system of the present disclosure. The thickener-free surfactant system is further utilized for achieving the cleansing composition. It is further specified that the presence of surfactants such as disodium laureth sulfosuccinate, cocamide monoethanolamine (CMEA), cocamidopropyl betaine (CAPB) is critical so as to achieve the thickener-free surfactant system. The absence of any of the surfactants specified above or replacement of the same with any other surfactant would affect the desirable properties of the thickener-free surfactant system.
EXAMPLE 1
Method of preparing the thickener-free surfactant system

[0069] The thickener-free surfactant as disclosed in the present disclosure
comprises a ternary surfactant system, said ternary surfactant system comprises
disodium laureth sulfosuccinate, cocamide monoethanolamine (CMEA),
cocamidopropyl betaine (CAPB) as primary (1°) surfactant, secondary (2°)
surfactant and tertiary (3°) surfactant respectively. The thickener-free surfactant
system was prepared by following steps:
[0070] Step 1: Disodium laureth sulfosuccinate, cocamide monoethanolamine
(CMEA), cocamidopropyl betaine (CAPB) were added together to obtain a first
mixture.
[0071] Step 2: The first mixture was heated at a temperature in a range of 60-70°C
while constantly mixing at a speed of 500RPM for about 30 minutes.
[0072] Step 3: The first mixture was cooled at a temperature for around 24 hours
to obtain the thickener-free system
[0073] Step 4: Citric acid was added to the thickener-free system adjusting the pH
in a range of 5-6.
[0074] The viscosity of the thickener-free system was further measured at 27°C to
check whether said thickener-free system is showing the desired viscosity or not.
[0075] The amount of each surfactant i.e. Disodium laureth sulfosuccinate,
cocamide monoethanolamine (CMEA), cocamidopropyl betaine (CAPB) used to
arrive at the final composition of the present disclosure, varied as per the working
examples of the present disclosure.
EXAMPLE 2
Working concentrations of the surfactants of the present disclosure
[0076] Table 1 depicts the working weight percentages (wt.%) of the surfactants
used for preparing the thickener-free surfactant system as disclosed in the present
disclosure. It further depicts that the use of all the surfactants within the working
wt.% range is critical for providing the thickener-free surfactant system with
desired viscosity. It can be inferred from Table 1 that disodium laureth
sulfosuccinate, cocamide monoethanolamine (CMEA), cocamidopropyl betaine
(CAPB) having a working wt.% in a range of 7-10%, 5-7% and 3-5% (as active

matter) respectively, are providing viscosity >3000 in the pH range of 5-6. Therefore, Table 1 exhibits the desired viscosity without the need of any external thickening agent.

[0077] Table 2 depicts the Working Examples (WE) 1 to 3 depicting the amount of
surfactant taken to arrive at the final composition of the present disclosure. By
referring to WE-1, surfactant system comprising lOg, 5g and 3g of disodium laureth
sulfosuccinate, CMEA and CAPB showed a viscosity of 3200 cps. Therefore, the
amount of each surfactant used in WE-1 to arrive at the final composition of the
present disclosure were within the disclosed weight percentage range. In WE-2, the
surfactant system that exhibited a viscosity of 4900 cps comprised lOg, 5g and 5g of
disodium laureth sulfosuccinate, CMEA and CAPB respectively. Therefore, the
amount of each surfactant used in WE-2 to arrive at the final composition of the
present disclosure, were within the disclosed weight percentage range. Similarly, the
surfactant system in WE-3, that exhibited a viscosity of 3200 cps comprised lOg, 7g
and 3g of disodium laureth sulfosuccinate, CMEA and CAPB respectively.
Therefore, the amount of each surfactant used in WE-3 to arrive at the final
composition of the present disclosure, were within the disclosed weight percentage
range.
[0078] Therefore, it can be inferred that WE-1 to WE-3 were as considered as the
working examples of the present disclosure.
[0079] Further the process of preparing the surfactant system as disclosed in WE-1
to WE-3 was carried out in a similar manner as described in example 1.
[0080] For instance, following steps were taken to prepare 20g of the surfactant
system disclosed in WE-2:
[0081] Step 1: 20% stock solution of disodium laureth sulfosuccinate and 20%
stock solution of CAPB were prepared.
Step 2: lOg of 20% stock solution of disodium laureth sulfosuccinate, lg of 20%
stock solution of CMEA and 5g of CAPB were added to arrive at the final
composition of the surfactant system disclosed in WE-2, wherein final active
concentration of disodium laureth sulfosuccinate, CMEA and CAPB was lOg, 5g,
and 5g respectively, and wherein the said surfactant system yielded a viscosity of
4900 cps.
EXAMPLE 3
Non-Working Examples of the surfactant system of the present disclosure

[0082] Table 3 depicts the Non-Working Examples (NWE) 1 to 7 depicting the individual weight percentages. By referring to NWE-1 to NWE-4, it can be observed that the binary surfactant systems using two surfactants did not show desired viscosity. Further, it can be observed that replacing any surfactant as disclosed in the present disclosure with any other surfactant did not exhibit desired properties. In case of NWE-5, the ternary surfactant system comprising CAPB and lauryl glucoside instead of CMEA and CAPB as 2° and 3 surfactants respectively, was not showing desired viscosity. Similarly, in case of NWE-6, replacement of CAPB with decyl glucoside in the surfactant system failed to show desired viscosity. In NWE-7, the replacement of CAPB with lauryl glucoside results in a less viscous surfactant system. Therefore, it can be inferred that NWE -1 to NWE -7 did not exhibit desired viscosity of >3000 cps due to the absence of any one of the surfactant as disclosed in the present disclosure or replacement of the same with any other surfactant.

[0083] As depicted in Table 4, it can be observed that Non-Working Examples 8-25 did not show the desired viscosity of >3000 cps as weight percentage of disodium laureth sulfosuccinate was less than the range of 7-10% as disclosed in the present disclosure. It can be further observed from the examples mentioned in Table 4 that by using disodium laureth sulfosuccinate below 7% in the surfactant system, the surfactant system provides a milky appearance in the solution which is not desirable.
[0084] Table 5 depicts Non-Working examples 26-36. It can be observed that the NWE 26-36 did not exhibit desired viscosity of more than 3000 cps as wt.% of

CMEA was outside the range disclosed in the present disclosure. It can be observed that the NWE-26 to 30, and NWE-35 to 36 comprise CMEA below 5% provides a clear solution with viscosity less than 3000 cps which is not desirable. In NWE-32 to 34, CMEA was more than 7%, thereby, providing a milky appearance in the solution without exhibiting desired viscosity.
[0085] Table 6 depicts Non-Working Examples (NWE) 37-41. As depicted in Table 6, it can be observed that NWE-37 to 41 did not exhibit desired viscosity as the wt.% of CAPB is outside the range of 3-5% of the present disclosure.

[0086] Therefore, the combination of surfactants such as disodium laureth sulfosuccinate; cocamide monoethanolamine (CMEA); and cocamidopropyl betaine (CAPB) in the disclosed wt.% ranges is essential to have a desired viscosity of >3000 cps. Replacing even a single surfactant with another surfactant does not provide the desired viscosity Also, deviating from the disclosed weight ranges does not exhibit the desired result.
EXAMPLE 4
Method of preparing the cleansing composition
[0087] In the present disclosure, the cleansing composition was prepared by utilizing the thickener-free surfactant system as disclosed above in the disclosure. Further, the cleansing composition comprises at least one excipient selected from a group consisting of emollient, emulsifier, chelating agent, preservative, UV stabilizer, bioactive, diluent and combinations thereof. The cleansing composition as disclosed in the present disclosure was prepared by following steps:
[0088] Step 1: The thickener-free surfactant system was obtained as disclosed in the present disclosure.
[0089] Step 2: The surfactant system was contacted with the at least one excipient
selected from a group consisting of emollient, emulsifier, chelating agent,
preservative, UV stabilizer, bioactive, diluent and combinations thereof was added
in said thickener-free surfactant system to arrive at the final cleansing composition
of the present disclosure, wherein the emollient is selected from a group consisting
of glycerine, tocopheryl acetate, sodium PCA, PEG 400, jojoba oil, iso propyl
myristate, D-panthenol, and combinations thereof, the emulsifier is selected from a
group consisting of polysorbate-20, polysorbate-40, polysorbate-60, polysorbate-
80, PEG-40 hydrogenated castor oil, PEG-7 glyceryl cocoate, and combinations
thereof, the chelating agent is either di sodium EDTA or tetra sodium EDTA, the
preservative is selected from a group consisting of DMDM hydantoin, parabens,
sodium benzoate, phenoxy ethanol, methyl isothiothiazolinone,

methylchloroisothiothiazolinone, potassium sorbate, and combinations thereof, the UV stabilizer is selected from a group consisting of 3-benzophenone, 4-benzophenone, butyl hydroxytoluene (BHT), diluent selected from group consisting of water, polyhydric alcohols, vegetable or synthetic oils and combinations thereof, the bioactive is selected from a group consisting of vitamin, provitamin, mineral, α- & β-hydroxy acid, modified metal salt, natural extract, and combinations thereof.
[0090] Although, the process of preparing the cleaning composition is very known in the art. The above-mentioned procedure can also be utilized for preparing the cleansing composition having the thickener- free surfactant system.
