FIELD OF THE INVENTION
[0001] The present disclosure relates to the field of personal care beauty products, in particular a sensorially superior low total fatty matter (TFM) soap bar and a process for preparation of the same. 5
BACKGROUND OF THE INVENTION
[0002] Soap bars are graded according to the content of total fatty matter (TFM). Toilet grade formulations contain high TFM are known as Grade 1 and Grade 2 formulations. There has been considerable research undertaken to reduce the TFM in
0 soap bars without majorly affecting their cleansing properties. Soap bars with high
surface active agents and low TFM contain low amount of sodium salt of fatty acids (C12–C18).
[0003] Soap bars with low TFM suffer from drawbacks such as reduced moisture retention, high cracking tendency, and soap breakage. Cracking of soap, also referred
5 to as wet-cracking is generally a result of repeated contact of soap bar with water and
subsequent drying; something that will inevitably happen when soap is used. In addition, there are many other factors that play a crucial role in cracking of soap which include shape of the bar, and process parameters involved in the manufacture of soap, such as extrusion temperature, imperfect mixing of components during extrusion, and
0 lower concentration of C12–C18 fatty acid salts. The cracks which develop on a soap
impart an unpleasant appearance to the soap bar. Moreover, at times, if the cracks develop sharp edges they can also be irritating, if not harmful, to the human skin, especially to the more tender parts. Thus, it is important to ensure that soaps are designed in such a way that they do not develop cracks on usage. Efforts in that
5 direction have been made in the past. One of the ways to tackle this peculiar problem
is addition of structurants to the soap. Different polysaccharides such as starches and celluloses have been used as structurants in order to address the above issue, but each one of them suffers from one limitation or the other.

[0004] Several attempts have been made in the past to reduce the amount of fatty acids
and various auxiliary and active substances.
[0005] WO2011080101 discloses a low TFM extruded personal washing bar
comprising a continuous phase, said continuous phase being substantially free of water
soluble detergent builder.
[0006] WO2010089269 discloses another low TFM extruded personal washing bar
comprising having a continuous phase including 20% to less than 45% fatty acid soap
in which the fatty acid soap comprises at least 30% saturated fatty acid soaps based on
the total weight of the soap. Further, the inert fillers were tried to replace the fatty
acids and other essential substances, however, these attempts reduced the desired skin
feel and other sensorial properties.
[0007] WO2001/042418 and WO2006/094586 disclose the use of amorphous alumina
or inorganic aluminum silicates. Further, US6440908 discloses the use of borates as
fillers. Still further, US2007/0021314 and US2007/0155639 describe use of starch and
synthetic surfactants together with hydrocarbons, moisturizers and free fatty acid and
mixtures thereof.
[0008] WO2013076047 discloses a soap bar composition comprising, in addition to
fatty acid soap and other ingredients, such as an adjuvant selected from suitable
starchy materials such as natural starch (from corn, wheat, rice, potato, tapioca and the
like), pre-gelatinzed starch, various physically and chemically modified starches and
mixtures thereof.
[0009] However, it has been observed that starches, specifically cornstarch, when used
in soap bar formulations impart a drag feel during soap usage on body. Also, the fillers
like corn starch and kaolin affects the properties of the soap bar and may not be able to
impart the desired level of efficacy, with regards anti-cracking properties and sensorial
aesthetics.
[0010] There is a need for soap bars which do not have problems as mentioned in the
prior art. Moreover, it is desirable that soap bars should not suffer from the defect of

cracking and also have a composition which contains relatively low levels of the significantly more expensive components rendering the soap bar as cost effective. [0011] Accordingly, it is the object of the present invention to manufacture a soap bar using low cost raw materials without affecting the desired properties of soap bar.

Definitions:
[0016] For convenience, before further description of the present disclosure, certain
terms employed in the specification, and examples are collected 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.
[0017] 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.
[0018] 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”.
[0019] 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 steps.
[0020] The term “including” is used to mean “including but not limited to”,
“including” and “including but not limited to” are used interchangeably.
[0021] 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 or testing of the disclosure, the preferred

methods, and materials are now described. All publications mentioned herein are incorporated herein by reference.
[0022] The term “soap noodles” refers to soap in the form of noodles. Soap noodles are made through the blending of oils, with base, such as caustic soda (NaOH) coupled with moisture (water) and other raw materials in minute (small) quantities. Soap noodles are made from vegetable oils, such as palm oil, coconut oil or olive oil, and/or animal fats (tallow). These are 'saponified', usually using sodium hydroxide, to form a sodium salt of the fatty acids. Soap noodles constitute the very basic form of soap. Different specifications of soap noodles are used depending on the type of soap to be manufactured e.g. toilet soap, laundry soap, translucent soaps, high-lather, medicated, etc. Soap noodles are blended with other raw materials such as fragrances and coloring to eventually make soap as the final product.
[0023] The term ‘stamping’ refers to the stamping step which is conducted during the formation of soap wherein around 50-60 or more bars per minute are stamped in a conventional soap line having several bars stamped in parallel. Stamping speed of 55-60 strokes/minute is considered as good stamping speed, whereas stamping speed of 30-35 strokes / minute is considered as disappointing.
[0024] Grade 2 soap is a soap with minimum 70 % total fatty matter and alcohol insoluble matters not more than 10%.

EXAMPLES
[0118] 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.
Example 1
Materials and methods
[0119] Process for the preparation of soap bar: The soap bar was prepared by following process: soap comprising 85% of C16 to C18 fatty acids and 15% of C12 to C14 fatty acid was mixed with alpha olefin sulfonates (solid), alpha olefin sulfonates, PEG-90M, glycerin, sodium silicate, talc, soda ash, titanium dioxide, sodium chloride, and fragrance at a temperature in the range of 20 ᵒC to 48 ᵒC, for a period of 15

minutes to obtain a mixture. The mixture was milled at a temperature in the range of 6 ᵒC to 10 ᵒC by passing through rollers having chilled water circulation system, to obtain a uniform homogeneous product, which was extruded at a temperature in the range of 30 ᵒC to 48 ᵒC to obtain plodded slug. Subsequently, the slug was cut into a pre-determined size and stamped to obtain low total fatty matter soap bar.
Example 2
Soap bars with varying weight percentage of components:
[0120] Skin conditioning is important for consumers as they are bothered if their skin
feels dry as well as consumers are likely to be disappointed if their soap bar does not
last long enough, or if cracks appear too quickly while using the product.
[0121] PEG-90M acts as a foam booster, slip agent and is a water-soluble product
designed to reduce drag & impart a smooth, lubricious after-feel. Glycerin, a
humectant, exhibits good physical properties, and acts as a distinct additive offering
conditioning benefits. It was surprisingly found that the weight ratio of PEG-90:
glycerin is very critical for soap bars. The weight ratio 1:40- 1:70 of PEG-90 and
glycerin in soap bar provided for superior structural and sensorial attributes.
[0122] Different soap bars A, B, C, D, E, and F having compositions as shown in
Table 1 were prepared by a process as discussed in Example 1.
[0123] Table 1

[0124] The weight ratio of PEG-90M: glycerin in soap samples A, B and E falls outside the working range (1:40- 1:70). The aforementioned soap bar samples were sticky in nature which to a large extent affected the stamping efficiency. Additionally the sensorial attribute, i.e., the bar glide was less than the grade 2 benchmark soap. [0125] Bar soap samples C and D were formulated with talc as filler and PEG-90: glycerin weight ratio in the range of 1:40-1:70. Both the samples did not exhibit cracking, therefore not only the sensorial attributes of the soap bar increases but also there was increase in the long-lastingness of soap bars, addressing a major consumer concern of the end users.
[0126] Additional feature in the bar soap sample C and D was the silicate to water ratio. Sodium silicate acts as a binder in the low TFM soap bars having high moisture content and also makes the mass harder and non-sticky which aids for better processability of the soap bar. It was inferred with due experimentation that when the ratio of sodium silicate to water was in the range of 1:3 - 1:20 better results were observed with regards to processability.
[0127] Soap sample F had higher weight percentage of surfactant which led to a soft sticky soap mass in which stamping was difficult. With regards to soap bar property and sensorials lather volume was beyond standard requirements.
Example 3
Soap composition with corn starch and kaolin as binders:

[0128] Binders are also critical component in the manufacturing of soap bars. In order to determine whether the effect of binder in the soap bar, soap bar samples G and H were prepared with corn starch and kaolin as binders respectively as is exemplified in Table 2.

[0130] As is clear from Table 2, that the soap bar sample G, despite the ratio of PEG-90M : glycerin, in the working range, the substitution of binder talc by corn starch resulted in soap bar sample which had cracks in it as well as the sensorial aesthetics were also inferior compared to that of benchmark grade 2 soap.
[0131] With regards to soap bar sample H, kaolin was used as binder, which resulted in reduction of volume of lather and therefore the glide on skin reduced during use thereby reducing the sensorial likeability.
[0132] Thus, based on the aforementioned results of various experiments, it can be concluded that, in soap bars which comprise of high molecular weight PEG’s and glycerin in the weight ratio of 1:40 to 1:70, along with other excipients as mentioned in the working examples, are substantially superior; both structurally and sensorially. There was a significant reduction in bar stickiness while maintaining hardness within acceptable limits. Furthermore, the soap bars of the present invention are also cost effective, as low levels of the expensive components have been used.
[0133] Overall the disclosure provides for a low total fatty matter (TFM) soap bar which has structurally and sensorially superior aesthetics.
[0134] Although the subject matter has been described in considerable detail with reference to certain examples and implementations thereof, other implementations are possible.
