SUNLESS TANNING |
摘要 |
This invention relates to a topical sunless tanning composition, in particular a topical sunless tanning composition which provides an immediate colour effect. There is much interest in effectuating a tan via cosmetic means. Most prominent among the sunless tanning agents is dihydroxyacetone (DHA, which is also chemically known as 1,3-dihydroxy-2-propanone). However, a problem with using DHA to tan the skin is the length of time it takes for the skin to develop colour (from 3 to 12 hours after application in general). Thus, in a first aspect of the invention, a topical sunless tanning composition is provided, the topical sunless tanning composition comprising: (a) 0.01-10, preferably 0.1-5 w/w a polyphenol selected from the group consisting of (+)-catechin, (−)-catechin, (+)-epicatechin, (−)-epicatechin, epigallocatechin gallate, (−)-epigallocatechin, (−)-catechin gallate, epicatechin gallate, or mixtures thereof; (b) A peroxidase or laccase (c) 0.0001-3 preferably 0.001-1, most preferably 0.01-1 w/w hydrogen peroxide or a hydrogen peroxide generator when peroxidase is present; and (e) A dermatologically acceptable vehicle. |
