| titleOfInvention | Hydroxytyrosol derivatives, their preparation and use in personal care |
| abstract | Disclosed are hydroxytyrosol derivative compositions comprising compounds of formula 2, methods for their manufacture and their use in personal care products. The lipophilic hydroxytyrosol carbonate ester compounds can be manufactured by oxidizing substituted hydroxybenzaldehyde compounds with an oxidizing agent, such as hydrogen peroxide, under mild conditions. The method comprises enzymatically esterifying 4- (2-hydroxyethyl) phenol to form a corresponding ester, introducing a formyl group ortho to the phenolic hydroxyl group of the ester to form a lipophilic formyltyrosol ester; oxidizing the lipophilic formyltyrosol ester with a peroxide compound to form a lipophilic hydroxytyrosol ester compound; and reacting the lipophilic hydroxytyrosol ester compound with a carbonate derivative to form the lipophilic hydroxytyrosol carbonate compound. These compounds can be used as anti-aging compounds in a wide variety of personal care compositions that are stable to oxidation. |
