Abstract
An oil-in-water cosmetic composition comprising: compound of thipyridinone type; one or more Polyglyceryl Fatty Acid Ester; an oil phase; and wherein the oil-in-water cosmetic composition is a macroemulsion and wherein the compound of thipyridinone type penetrates rapidly and in a high amount.
Claims15
An oil-in-water cosmetic composition comprising:
- I) at least one compound selected from a compound of formula (I), a tautomer of formula (I′), their salts, their optical isomers, racemates, solvates, or a mixture thereof:
- wherein Formulas (I) and (I′):
- R1 denotes a radical chosen from:
- a) a hydrogen atom;
- or
- 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, or
- 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;
- or
- iv) a C5-C12 aryl group optionally substituted with one or more hydroxyls and/or with one or more C1-C8 alkoxy radicals, and
- R3 denotes a radical chosen from:
- a) a hydrogen atom, or
- b) a saturated linear C1-C10 or branched C3-C10 alkyl group;
- II) one or more polyglyceryl fatty acid esters selected from the group consisting of polyglyceryl-4 caprate, polyglyceryl-6 dicaprate, polyglyceryl-6 dioleate, polyglyceryl-6 distearate, and mixtures thereof;
- and
- III) one or more oils;
- and
- wherein the penetration of the at least compound of item I) is improved through the use of one or more polyglyceryl fatty acid esters;
- wherein the pH is from about 4.5 to about 6.5;
- and
- wherein the oil-in-water cosmetic composition is a macroemulsion.

- and
- III) one or more oils;
- and
- wherein the penetration of the at least compound of item I) is improved through the use of one or more polyglyceryl fatty acid esters;
- wherein the oil-in-water cosmetic composition is a macroemulsion;
- wherein the pH is from about 4.5 to about 6.5;
- and
- wherein the weight percentages are based on the total weight of the cosmetic composition.
