FIELD OF INVENTION
[0001]
The present invention relates to a cosmetic composition. The present invention in particular relates to a transparent aqueous composition comprising hydroxy acids for caring and treating keratin materials.

BACKGROUND OF INVENTION
[0002]
Cosmetic products, preferably skin-care and body-care products are the most sought cosmetics in everyday life. Consumers of various skin types and textures look for products which suit and benefit them the most. Thus, the market is flooded with various skin-care products. However, these skin-care products do 10 not serve consumers of all skin types and do not meet the expectations of the consumers aesthetically, sensorially as well as in their performances.
[0003]
Formulating cosmetic compositions to meet consumers’ sensorial, and aesthetic requirements while exhibiting superior performance efficacy is demanding. In particular, there exist challenges in formulating transparent stable 15 skin-care products with an increased amount of skin-actives such as keratolytic agents. Such keratolytic agents are usually lipophilic in nature and may solubilize more difficultly when introduced in increased concentrations into cosmetic compositions comprising a high content of water. Indeed, keratolytic agents may crystallize and/or sediment, thus resulting in a decreased bioavailability thereof, 20 and/or in compositions lacking transparency.
[0004]
Accordingly, there is a need in the state of art to formulate transparent aqueous cosmetic composition which could provide superior sensorial effect and superior performance in treating various skin-related issues such as acne, oil reduction, pore minimization, and shine control as well as for imparting care to skin. 25
[0005]
Further, the formulation of environmentally friendly cosmetic products, which are designed and developed considering environmental issues, is becoming a major goal in an effort to meet global challenges. It is therefore essential to 2
propose more sustainable compositions, preparation processes and ingredients to
address these environmental concerns.
[0006]
In this context, it is important to develop new cosmetic compositions with a better carbon footprint, particularly by promoting the use of renewable raw materials and / or materials with a good index of naturalness and / or materials of 5 natural origin and, more particularly, materials of plant origin while reducing the use of compounds of petrochemical origin.

Sclerotium gum is a very high molecular weight homopolysaccharide obtained by fermentation of a glucose-based substrate by the filamentous fungus Sclerotium rolfssii. The backbone of sclerotium gum is composed of β-D glucose residues connected by β(1-3) glycosidic bonds with one β(1-6)- D-glucose side chain every three glucose residues, which prevents chain aggregation. Sclerotium 5 gum is also called sclerote gum(s) or scleroglucan gum or scleroglucan and gives only glucoses after hydrolysis. Sclerotium gum is commercially available and in particular, is marketed under the name ACTIGUM CS by SANOFI BIO INDUSTRIES, and in particular ACTIGUM CS 11, and under the name AMIGEL and AMIGUM by ALBAN MULLER INTERNATIONAL, or else under the name 10 Tinoderm SG-L by BASF. This sclerotium gum can also be modified, in particular by enzymatic treatments or by using modified strains. However, in a preferred embodiment, the sclerotium gum is not modified.
[0075]
In an embodiment, sclerotium gum is present in an amount ranging from 15 to 85% by weight, and preferably 15 to 45% by weight, with respect to total weight 15 of the thickener.
[0076]

Phospholipids and/or lysophospholipids present in thickener are lecithin and/or lysolecithin. Lecithin can be obtained from various sources, particularly soy, 15 sunflower, milk, eggs, rice, maize, and the like. Commercially available Lecithin include Solec SF 10 from The Solae Company, Emulmetik 300 and Solec from Lucas Meyer Cosmetics, or from Cargill, Natterman, or Lipoid. Lecithins are typically obtained from oil which can be extracted from seeds by pressing or with the aid of suitable solvents. Once the oil is obtained, lecithin is extracted for 20 example by degumming the oil. It can then be filtered. Advantageously lecithin contains at least 60% polar lipids insoluble in acetone. It contains different phospholipids including phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidic acid. Hydrogenated lecithin can be obtained from different methods known per se. For instance, according to one method that 25 can be used, lecithin is dissolved in a solvent system then hydrogenated for 1 to 20 hours under 10 to 200 kg/cm2 of hydrogen pressure at a temperature of 50-90°C in the presence of a catalyst. Hydrogenation improves lecithin stability, in particular with regard to oxidation or other degradations. These hydrogenated lecithins are available from Lucas Meyer Cosmetics under the references Emulmetik 320, 30 Emulmetik 950 (non-exhaustive list). Other hydrogenated lecithins are available
15
from Natterman or Lipoid. With regard to lysolecithin, it can be obtained for
example by enzymatic hydrolysis of phospholipids, thereby leading to the elimination of one or two fatty acid chains. These methods are well known to one of skill in the art. Lysolecithin is also commercially available, in particular under the name SLP-LPC70 from Tsuji Oil Mill Co., Ltd, Lysolecithin Kyowa from 5 Kyowa Hakko Kogyo Co., Ltd, or as Emulmetik 120, Emulmetik 350 and Emulmetik 355 from Lucas Meyer Cosmetics.

According to an embodiment, the composition of the present invention comprises at least one hydrotrope. 15
[0090]
In some embodiments, the composition may include one or more hydrotropes.
[0091] Most hydrotropes have aromatic structure with an ionic moiety, while some of them are linear alkyl chains, as listed below. Although hydrotropes noticeably resemble surfactants and have the ability to reduce surface tension, their small 20 hydrophobic units and relatively shorter alkyl chain distinguish them as a separate class of amphiphiles. Consequently, their hydrophobicity is not sufficient to create well organized self-associated structures, such as micelles, even with a high concentration.
[0092]
Common hydrotropic molecules include: sodium 1,3-benzenedisulfonate, 25 sodium benzoate, sodium 4-pyridinecarboxylate, sodium salicylate, sodium benzene sulfonate, caffeine, sodium p-toluene sulfonate, sodium butyl monoglycolsulfate, 4-aminobenzoic acid HCl, sodium cumene sulfonate, N,N-diethyl nicotinamide, N-picolylnicotinamide, N-allylnicotinamide, 2-methacryloyloxyethyl phosphorylcholine, resorcinol, butylurea, pyrogallol, N-30 picolylacetamide 3.5, procaine HCl, proline HCl, nicotinamide, pyridine, 3-
17
picolylamine, sodium ibuprofen, sodium xylenesulfonate, ethyl carbamate,
pyridoxal hydrochloride, sodium benzoate, 2-pyrrolidone, ethylurea, N,N-dimethylacetamide, N-methylacetamide, and isoniazid.
[0093] Cosmetically acceptable hydrotropes refer to hydrotropes that can be used in cosmetic compositions.

Example 2
Evaluation of the composition
[0132]
The compositions prepared in Example 1 were subjected to a series of evaluations to measure their pH, transparency, viscosity, and stickiness. The 5 performance of the compositions was also measured by determining skin color, skin hydration and reduction in sebum levels.
Transparency of the composition
[0133]
The transparency of the compositions was determined by measuring 10 transmittance using a UV-Vis 1800 spectrophotometer (Shimadzu) and the method of measurement is as follows.
[0134]
The undiluted sample composition was poured into a square-sided spectrophotometer cuvette with a side length of 10 mm and the light transmitted through the sample composition was measured using the spectrophotometer at a 15 wavelength of 700 nm. The measurement was made in transmission mode and the percentage of light transmitted through the sample composition at a wavelength of 700 nm was then determined. A baseline was established with distilled water. The tested composition was considered transparent when the transmittance reached at
24
least 40%, preferably at least 50%
of light at a wavelength of 700 nm without scattering it.
Viscosity measurements
[0135] Viscosity of the compositions was measured using a viscometer Rhéomat 5 200 PLUS equipped with a measuring system comprising a spindle 2 (M2) and its corresponding cup, and a thermostat-controlled bath.
[0136] Measurement was performed as follows: Spindle 2 was installed in the viscometer and the machine was set to zero. The cup was filled in with the composition to be tested, and then positioned within the thermostat-controlled bath. 10 Spindle 2 was then plunged within the cup, and the temperature was raised to 25°C. The viscosity measurement was performed when spindle 2 reached the correct temperature. The measurement was recorded after 10 min.
Evaluation of stickiness 15
[0137]
0.1mL of the composition to be tested was applied on half of the faces of trained panel consumers (16 females). Stickiness was evaluated immediately after product application, and 2 minutes post application. Stickiness level was graded on a scale from 0 to 15, with 15 being more sticky. 20
Performance Evaluation
[0138] A study was conducted on 60 female subjects aged between 20 and 40 years old, including all ethnicities. Subjects attended a baseline visit at time point D0, followed by 3 additional visits at time points D7 (7 days), D14 (14 days) and D28 (28 days – end of the study). After the baseline visit, subjects applied the 25 composition according to the invention once daily (at night): after washing their face with a regular face cleanser, and dabbing it dry, subjects applied the composition according to the invention uniformly with their index finger using circular motion for about 1 min or till the composition was fully absorbed into the skin. 30 25
[0139]
During each visit (D0, D7, D14, D28) and before any assessment, subjects washed their face with water only and without applying any product on the face prior to the visit. Subjects were then acclimatized at least 15 minutes at a temperature of 20 to 23°C and a hygrometry of 40 to 60%.
[0140]
The cutaneous state of the subjects' skin on the face was then evaluated by 5 an investigator, and a clinical scoring was affected to the following parameters: fine lines, skin plumpness, skin hydration, skin smoothness, shine (visual), glow and radiance, skin clarity and visibility of pores. Each parameter was graded on a scale ranging from 0 to 9.
[0141]
Further, the sebum casual level of the subject’s skin was measured using a 10 sebumeter® SM 815 (Courage & Khazaka) on the forehead, allowing the measurement of the skin sebum by means of a special tape which is sensitive to oil and becomes transparent in contact with skin oil (measurement based on grease spot photometry).
[0142]
Skin color was measured using a spectrocolorimeter® Minolta CM700d, 15 using the L*a*b* color system (CIE lab 1976). Skin hydration level was measured using a Corneometer® CM825 (Courage & Khazaka, Germany), such as to determine the level of humidity of the most external cutaneous layers of the stratum corneum. 20
Results
[0143]
Compositions C1 (according to the invention) and C2-C4 (comparative) were all found to be transparent and to have a viscosity comprised between 10 and 20 UD.
[0144]
Nevertheless, composition C1 according to the invention was shown to be 25 slippery upon application and non-sticky after application, while comparative compositions C2-C4 were considered sticky during and/or after application.
[0145]
In addition, composition C1 according to the invention was considered waterier, and led to a feeling of quick absorption on the skin, while comparative compositions C2-C4 were shown to absorb more slowly on the skin. 30 26
[0146]
The pH of composition C1 was further measured and was shown to be within the range of pH 4.8 to 5.4.
[0147]
Additional evaluations conducted on composition C1, demonstrated that said composition was capable of treating acne while providing improved hydration to the skin. Composition C1 was also shown to be performant in reducing the 5 visibility of fine lines and pores, reducing sebum levels, and reducing the shininess of the skin. Finally, composition C1 was shown to significantly improve skin plumpness, skin smoothness, radiance, clarity and hydration.
