COMPLETE SPECIFICATION
The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF INVENTION
[0001]
The present disclosure relates to the field of cosmetics, in particular, a gel composition for cleansing keratin material, preferably skin. The present disclosure also relates to a process of preparing the composition and methods thereof.
BACKGROUND OF INVENTION 5
[0002]
To achieve acne-free and radiant skin, an optimized cleansing contingent is always required. Delicate skin is highly sensitive to harsh soaps and surfactants with a high pH, which are very much prominent in basic cleansing products available in the market. Therefore, usage of such harsh cleansing products deteriorates sensitive and acne-prone skin over time.
[0003]
Although the available cleansing product claims their mild behaviour and deep 10 cleansing effect, they are loaded with the component which dries the skin. These components also lead to an unstable composition. Therefore, their storage stability and shelf-life are always a concern. It is difficult to retain their homogeneity throughout.
[0004]
The trend now moves towards gel-based cleansing products. However, the pitfall of such products is that they are generally light and, thus do not effectively remove oil, makeup, 15 sun filters, and external aggressors like pollutants, and dust. Also, these products lack sensorial or foamy feel as preferred by consumers in today’s market.
[0005]
Therefore, there is a need to develop a cleansing composition with a balanced combination of mild cleansing agents, which deeply purifies the skin without residual drying effects and has the desired product texture and stability. 20
SUMMARY OF THE INVENTION

however,
for convenience and completeness, particular terms and their meanings are set forth below.
[0014] 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.
[0015] The terms “comprise” and “comprising” are used in the inclusive, open sense, meaning 5 that additional elements may be included. It is not intended to be construed as “consists of only”.
[0016] The term "at least one" is used to mean one or more and thus includes individual components as well as mixtures/combinations. Similar definition applies to the term “at least two” used herein. 10
[0017] 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.
[0018] The term “including” is used to mean “including but not limited to”. “including” and 15 “including but not limited to” are used interchangeably.
[0019] The term “about” is used to mean an acceptable error range for the particular value as determined by one of ordinary skill in the art, which can depend in part on how the value is measured or determined, i.e., the limitations of the measurement system. For example, "about" can mean within 1 or more than 1 standard deviation, per the practice in the art. Where 20 particular values are described in the present disclosure, unless otherwise stated the term "about" meaning within an acceptable error range for the particular value should be assumed.
[0020] The term “auto foam product” is used to mean a product achieved by reducing the gelling agent in the gel composition. The viscosity is reduced by the reduction of the gelling agent and the liquid texture can be achieved.

[0025]
The present disclosure relates to a gel composition, preferably a cleansing composition. The disclosed embodiments of the present disclosure include a gel-based cleansing composition, a personal care product comprising the composition and a method for treating 25 keratin surface, such as skin. The various embodiments herein disclose a cleansing composition, particularly a transparent serum-like or gel cleansing composition comprising a combination of surfactants, fatty acids, and a gelling agent. The embodiments of the present disclosure provide a mild cleansing composition of low pH, without any residual drying effect. The composition is suitable for all types of skin, foamable, stable, and transparent over a 30 broader ambit of time and temperatures. In general, the majority of the cleansing compositions available in the market are harsh, impart dryness to the skin, suffer from stability issues at higher temperatures, and are not transparent enough. When such compositions are converted to a gel-based composition, the sensorial, foamability, and textural requirements of the 5
consumers are comp
romised. Hence it has become the need of the hour to provide a multifunctional cosmetic cleansing composition which provides improved sensorial and aesthetic properties on single and repeated usage, and at the same time, should be mild, transparent, and foamable providing anti-acne property along with no residual drying effect to skin. Accordingly, the present disclosure provides a gel composition balancing both sensorial 5 and transparency properties, with a unique combination of specific fatty acids and surfactants.

Preliminary Observation
[0087]
The compositions as prepared in Example 1 were analyzed to determine its prototype scoping. The composition C1 showed a unique transparent foam like soap wash. It showed the 5 formation of fast foam with high foam density. It had mild and deep cleansing sensory behaviour for acne and brightening of skin, without making skin dry and tight. The face wash comprising the composition C1 gently purified acne skin and back without drying the skin. Thus, it was observed that the gel composition of the instant Application is suitable for all types of skin, foamable, stable, and transparent. 10
[0088]
The composition CP(1) wherein the only fatty acid included was lauric acid, appeared as thick creamy and thus the requirement of the transparent gel wash was not met. The composition CP(2), wherein no fatty acid was included, resulted in, non-transparent and non-gel watery liquid. The composition CP(3), wherein the amino-acid based surfactant was not included, resulted in loose foam with a longer settling time. The composition CP(4), wherein 15 the gelling agent was absent, the composition remained in non-gel state. Composition CP(5), wherein the non-ionic surfactant was absent, gave non-transparent and non-gel product and the composition CP(6) wherein the active agent such as niacinamide was absent, resulted in formulation out of pH and exfoliation. Similarly, the absence of other components, such as salicylic acid disturbed the pH causing skin irritantion. 20
[0089]
From the above, it was observed that the composition C1 prepared according to the present disclosure exhibited desired pH, stability, exfoliation property, foaming characteristics, sensorial aspects which could be attributed to the presence of essential ingredients, such as combination of fatty acids and combination of surfactants along with gelling agent in desired weight percentages. 25
