Cleansing compositions with non-modified clay and polyglycerol surfactant
An object of the present invention is a cosmetic composition, in particular for cleansing the skin and/or skin appendages, comprising, in an aqueous physiologically acceptable medium: at least one non-modified clay selected from trioctahedral smectites, and at least one ester selected from esters of fatty acid comprising from 4 to 16 carbon atoms and polyglycerol comprising from 2 to 10 glycerol units, the ester:clay weight ratio being strictly greater than 1.
1 . A cosmetic composition which is an aqueous gel comprising, in an aqueous physiologically acceptable medium:
at least one non-modified clay selected from trioctahedral smectites,
and at least one mono-ester selected from mono-esters of fatty acid comprising from 4 to 16 carbon atoms and polyglycerol comprising from 2 to 10 glycerol units,
the mono-ester:clay weight ratio being strictly greater than 1.
2 . The composition according to claim 1 , wherein the non-modified clay comprises a quantity by weight of SiO 2 greater than or equal to 30% with respect to the total weight of the clay; and a quantity by weight of MgO greater than or equal to 10%.
3 . The composition according to claim 2 , wherein the non-modified clay comprises a SiO 2 /MgO weight ratio between 1 and 3.
4 . The composition according to claim 1 , wherein the non-modified clay further comprises a quantity by weight of Al 2 O 3 between 0% and 15% with respect to the total weight of the clay.
5 . The composition according to claim 1 , wherein the non-modified clay is selected from non-modified hectorite, non-modified stevensite and non-modified saponite.
6 . The composition according to claim 1 , wherein the non-modified clay is present in a content of between 0.1% and 10% by weight in relation to the total weight of the composition.
7 . The composition according to claim 1 , wherein the mono-ester is formed (i) from at least one fatty acid comprising an alkyl or alkenyl chain containing 4 to 16 carbon atoms and (ii) 2 to 10 glycerol units.
8 . The composition according to claim 1 , wherein the mono-ester of fatty acid comprising 10 carbon atoms and of polyglycerol comprising 4 glycerol units.
9 . The composition according to claim 1 , wherein the mono-ester is present in a content ranging from 0.5% to 10% by weight, with respect to the total weight of the composition.
10 . The composition according to claim 1 , wherein the mono-ester:clay weight ratio is greater than or equal to 1.05.
11 . The composition according to claim 1 , which comprises at least one polymer selected from oligo- or polysaccharides, acrylic and/or methacrylic polymers or copolymers, carboxyvinyl polymers, polyglyceryl acrylates or methacrylates.
12 . The composition according to claim 1 , wherein the aqueous medium comprises water and optionally one or more water-soluble organic solvent(s) at 25° C.
13 . A method for cleansing the skin and/or skin appendages, comprising the application on the skin and/or skin appendages of a composition according to claim 1 .
14 . The composition according to claim 2 , wherein the non-modified clay further comprises a quantity by weight of Al 2 O 3 between 0% and 15% with respect to the total weight of the clay.
15 . The composition according to claim 3 , wherein the non-modified clay further comprises a quantity by weight of Al 2 O 3 between 0% and 15% with respect to the total weight of the clay.
16 . The composition according to claim 2 , wherein the non-modified clay is selected from non-modified hectorite, non-modified stevensite and non-modified saponite.
17 . The composition according to claim 3 , wherein the non-modified clay is selected from non-modified hectorite, non-modified stevensite and non-modified saponite.
18 . The composition according to claim 4 , wherein the non-modified clay is selected from non-modified hectorite, non-modified stevensite and non-modified saponite.
19 . The composition according to claim 2 , wherein the non-modified clay is present in a content of between 0.1% and 10% by weight in relation to the total weight of the composition.
