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

FIELDOFINVENTION
[0001] The present disclosure relates to the field of cosmetics and personal care products. The present disclosure, in particular, relates to a biphasic cleansing composition for removing make up, cleansing or for caring a keratinous layer.
BACKGROUNDOFINVENTION
[0002] Generally, people are passionately inclined towards investing long hours to deck themselves with heavy and waterproof make up to look flawless. But on the other hand, people shy away from investing a minimal amount of time to remove the make up at the end of the day. However, the basis for obtaining a flawless skin is to maintain a clean and unclogged skin. Therefore, consumers are in a constant search for cosmetic products that can effectively and quickly remove make up.
[0003] Cleansers are commonly used products to clean up the skin. Though such traditional facial cleansers are sufficient to remove excess oil and dirt but are not effective in removing make up, in particular, waterproof make up. Also, such cleansers are harsh on sensitive and acne prone skin. One such alternative to traditional cleansers are biphasic cleansing compositions, also referred to as micellar water in the consumer market.
[0004] Micellar water products include predominantly water with an optimized ratio of exfoliating agents to remove all kinds of waterproof make up and dirt. Such products in the consumer market also claim to provide additional benefits like providing moisturized and bright skin, post use of those products. However, the so called versatile micellar water products tend to cause skin irritation due to the presence of high amounts of exfoliating agents and also leave the skin sticky due to the presence of undesirable amounts of oil phase ingredients.

[0005] Therefore, there is a need to develop biphasic compositions with desired amount of aqueous phase and oil phase ingredients in order to achieve an effective removal of make-up and also, to ensure nourished and brighter skin post use, while being suitable for all skin types.
SUMMARYOFTHEINVENTION
[0006] In an aspect of the present disclosure, there is provided a biphasic composition comprising: an aqueous phase comprising: (a) at least one alpha hydroxy acid; (b) at least one poly(hydroxy) acid; (c) at least one brightening active; (d) at least one anti-dullness active; and (e) water; and an oil phase comprising: (f) at least one emollient; and (g) optionally at least one antioxidant.
[0007] In another aspect of the present disclosure, there is provided a method for removing makeup from, cleansing and/or caring for the skin, the lips and/or the eyes, the body, or the hair, characterized in that the cleansing composition as described herein is applied to the skin, the lips and/or the eyes, or the hair.
[0008] In one another aspect of the present disclosure, there is provided a use of the composition as described herein for removal of makeup, for cleansing and/or for caring a keratinous layer.
[0009] These and other features, aspects, and advantages of the present subject matter will be better understood with reference to the following description and appended claims. This summary is provided to introduce a selection of concepts in a simplified form. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

DETAILEDDESCRIPTIONOFTHEINVENTION
[0012] 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
[0013] 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 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.
[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 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.
[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 “including but not limited to” are used interchangeably.
[0019] The term “INCI” is an abbreviation of International Nomenclature of Cosmetic Ingredients, which is a system of names provided by the International Nomenclature Committee of the Personal Care Products Council to identify cosmetic or personal care ingredients.
[0020] The term “oil” as used herein refers to compounds and/or mixtures of compounds which are water-insoluble, and which have a liquid appearance at a temperature of 25°C.
[0021] The term “biphasic” is used to mean a composition constituting a distinct aqueous and a distinct oily phase. According to the present disclosure, the two phases are separate with the aqueous phase forming the bottom or lower phase and the oily phase forming the upper or top phase. The two phases are not emulsified in each other at rest. However, the biphasic composition on mixing, such as shaking transforms into a turbid single phase composition, which is then applied onto a keratinous layer such as skin. The terms “biphasic” and “two-phase” are used interchangeably in the present disclosure. The biphasic composition is capable of transforming into a single phase composition and the single phase composition is capable of transforming into the biphasic composition.
[0022] The term “ silicone and alcohol free” or “free of silicones and alcohols” as used herein means that the cleansing composition as disclosed herein is essentially

free of any alcohol and/or silicone containing ingredients. In particular, “essentially free of any alcohol and/or silicone containing ingredients” means that the alcohol and/or silicone containing ingredients may be present in the composition in an amount of less than 1.0% by weight relative to the total weight of the composition, preferably less than 0.5% by weight, more preferably less than 0.1% by weight. In an embodiment, the composition is completely free of silicone. In another embodiment, the composition is completely free of alcohol. In yet another embodiment the composition is completely free of silicone and alcohol.
[0023] All percentages, parts and ratios are based upon the total weight of the formulations of the present disclosure unless otherwise indicated. 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. For example, a percentage range of about 0.01 % to 5.5 % should be interpreted to include not only the explicitly recited limits of about 0.01 % to about 5 %, but also to include sub-ranges, such as 2% to 3 %, 3 % to 4%, and so forth, as well as individual amounts, including fractional amounts, within the specified ranges, such as 2.84 %, and 3 %, for example.
[0024] 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. All publications mentioned herein are incorporated herein by reference.
[0025] The present disclosure is not to be limited in scope by the specific embodiments described herein, which are intended for the purposes of

exemplification only. Functionally equivalent products, compositions, and methods are clearly within the scope of the disclosure, as described herein.
[0026] Embodiments herein provide a biphasic composition, preferably an alcohol and silicone free biphasic composition for removal of makeup, for cleansing and/or for caring a keratinous layer. The disclosed embodiments include a biphasic composition, a method for removing makeup from, cleansing and/or caring for the skin, the lips and/or the eyes, the body, or the hair, and use of the composition for removal of makeup, for cleansing and/or for caring a keratinous layer. In various embodiments herein, the composition is a biphasic cleansing composition having improved cosmetic properties, which addresses the drawbacks of existing cleansing products. Generally, biphasic cleansing products may be harsh and non-suitable for acne prone skin due to the presence of higher amounts of alpha hydroxy acids. Also, such biphasic cleansing products may not be stable enough to retain their phase characteristics for a prolonged period of time and hence are deficient in providing additional skin care benefits. Hence, the composition according to embodiments herein is an alcohol and silicone free biphasic composition that is capable of transforming into a single phase composition, stable across temperatures, provides effective make up removal, soft peeling, and therefore, mild and suitable for even sensitive skin types such as acne prone skin. Additionally, the composition provides enhanced skin care benefits such as instant and progressive brightness of the skin; even skin tone with reduced acne scars and pigment spots; smooth and hydrated skin post the regular use of the composition. The embodiments herein, further, include a method for the preparation of the biphasic composition.

[0165] Skin and eye non-irritant feature of the compositions were assessed using a combination of an instrumental test, and qualitative consumer tests.
HCE in vitro test
[0166] The SkinEthic™ HCE (Human Corneal Epithelium) reconstructed cornea model has been adopted in OECD TG 492 for the prediction of eye irritation of chemicals/raw materials.
[0167] 30μl-30min protocol: 30μl of composition was topically applied on SkinEthic™ HCE model. Tissues were incubated for 30min in 37°C, 5% CO2 and 95% humidity, following 30min of post-soak. Viability was determined by the MTT conversion test to predict irritation.
Result

[0168] The composition C1 was found to be acceptable with no major skin or eye irritation as reported by the HCE test.
PIRI PIRI test
[0169] Sensation of skin discomfort, such as skin and eye irritation or itch and the level was assessed by the sequential monadic evaluation in blind, randomized design of the composition C(1) and the commercial product CP(9). Twenty-eight volunteers, who are reactive to skin discomfort caused by cosmetic products and trained for the standard application method were involved in the study. The volunteers were instructed to evaluate for any skin discomfort caused on their upper cheek from immediate to 5 minutes after application. For the mean score of each type of discomfort, significant difference was determined with p<0.05.
Results
[0170] With regards to itch as a skin discomfort, a mean score of 0.25 was reported for C(1) when compared to CP(9) with a mean score of 0.11, which signified that the composition C(1) resulted in significantly less itch than CP(9).
Qualitative consumer test-1
[0171] The composition C(1) according to the present disclosure and the commercial product CP(2) were qualitatively evaluated for its non-irritant feature towards the skin and the eyes.
Results
[0172] Majority of the volunteers (16-19 of the volunteers) observed that C(1) did not sting or irritate the eyes or did not leave bitter taste on the lips when compared to the commercial product CP(2).
Qualitative consumer test-2

[0173] The composition C(1) according to the present disclosure and commercial products CP(2) and CP(3) were qualitatively evaluated for their skin and eye non-irritant feature.
Results
[0174] All the volunteers reported that the composition C(1) did not irritate eyes or leave an unpleasant “chemical” taste on lips when compared to the commercial products CP(2) and CP(3).
[0175] Thus, the composition C(1) according to the present disclosure with the appropriate ingredients with optimum dosage of skin peeling actives such as AHA and PHA, and an optimized pH of 4.5 was suitable for the skin without causing any skin or eye irritation.
VI. Immediate brightening
[0176] Immediate brightening effect provided by the compositions were assessed using a combination of an instrumental test, a qualitative consumer test, and a quantitative consumer test.
Instrumental test
[0177] Fourteen healthy volunteers with fair, medium and darker skin tones and oily skin were recruited for the instrumental test and the immediate skin brightening effects were assessed. Instrumental evaluation was done on before and after product application to capture evolution in skin color & shine using Minolta Spectrophotometer CD 700 & Newtone’s Lightcam.
[0178] Compositions tested: Compositions C(1) and commercial products CP(2), CP(4), CP(5), CP(6), CP(7) and CP(8).
[0179] Protocol for Chromasphere® measurement:

1) The volunteers were instructed to wash their face with water and leave for acclimatization in standard condition (Temperature :21±1 °C; RH: 45±5%) for 30mins.
2) T-0 baseline measurement was obtained on Chromasphere; with cheek and forehead as the zone of assessment.
3) Product was applied in 6 strokes using 2.5ml of the composition taken on a cotton pad, as per randomization using standard protocol.
4) T-imm measurement was obtained on Chromasphere.
5) Parameters assessed: For skin colour changes: L, C, hue(H) and dE94; For gloss shine: dC.
Results
[0180] The difference in skin lightening from T0 base line measurement and respective time point (T-imm) post application of the product is represented as a dL value. The dL values obtained for the compositions tested is summarized in Figure 1 A. Similarly, the change in saturation values, represented by dC is summarized in Figure 1B. The dC values confirmed that the composition C(1) according to present disclosure provided significantly increasing saturation and made the skin color more vivid and intense. The change in hue of the skin is represented by dH and is summarized in Figure 1C.The overall colour change from base line is represented by dE94 and is summarized in Figure 1D. Thus, the composition C(1) of the present disclosure exhibited significant brightening and skin saturation effects.
Qualitative consumer test-1
[0181] The composition C(1) according to the present disclosure and the commercial products CP(1) and CP(2) were qualitatively evaluated for its immediate skin brightening effects.
Results

[0182] All of the volunteers observed that C(1) was able to provide an instant glow with a soft skin post use when compared to the commercial products, which left a sticky inspite of providing brightening affects.
Quantitative consumer test
[0183] The composition C(1) according to the present disclosure and commercial facial cleanser products CP(1) and CP(2) were quantitatively evaluated for their ability to offer skin respect.
Results
[0184] 87% of volunteers reported a significantly better cleansing efficacy with skin brightening effects as provided by the composition C(1) when compared to both commercial products CP(1) and CP(2).
[0185] Thus, the composition C(1) according to the present disclosure, comprising active cocktail like AHA, PHA, brightness active like niacinamide at active level and low pH showed higher efficacy of skin rejuvenation and skin brightening .
