Abstract
The instant disclosure relates to oil-in-water compositions comprising: (i) compound of thiopyridinone type; (ii) a blend of natural emulsifiers; wherein the oil-in-water cosmetic composition is physically stable.
Claims19
An oil-in-water cosmetic composition comprising:
- i) at least one compound selected from compounds of formula (I) and tautomer of formula (I′) below or their salts;
- and their optical isomers, racemates, and/or solvates such as hydrates, alone or as a mixture:
- In which Formulas (I) and (I′):
- R1 denotes a radical chosen from:
- a) a hydrogen atom;
- b) a saturated linear C1-C10 or branched C3-C10 alkyl group optionally substituted with one or more groups, which may be identical or different, chosen from:
- i) —O—R3
- ii) —S—R3,
- R2 denotes a radical chosen from:
- a) a hydrogen atom;
- b) a saturated hydrocarbonated group linear C1-C12 or branched C3-C12 or cyclic C3-C8, optionally substituted with one or more groups, which may be identical or different, chosen from:
- i) —O—R3
- ii) —S—R3
- iii) —C(O)—O—R3;
- iv) a C5-C12 aryl group optionally substituted with one or more hydroxyls and/or with one or more C1-C8 alkoxy radicals;
- c) a C5-C12 aryl group optionally substituted with one or more hydroxyls and/or with one or more C1-C8 alkoxy radicals
- R3 denotes a radical chosen from:
- a) a hydrogen atom;
- b) a saturated linear C1-C10 or branched C3-C10 alkyl group;
- ii) at least two or more natural emulsifiers;
- and
- wherein the oil-in-water cosmetic composition is physically stable.
