Abstract:
Provided is a 3,5-dihydroxybenzoic acid derivative, which shows an elastase inhibitory effect and an excellent effect of scavenging free radicals generated by UV irradiation, has an excellent anti-aging effect, and is useful for an anti-aging cosmetic composition. The 3,5-dihydroxybenzoic acid derivative is a compound represented by a formula 1, substituted with hydroxyl groups at 3,5-position thereof and the amide group being substituted with a bulky substituent. The 3,5-dihydroxybenzoic acid derivative is obtained by the method comprising the steps of: (A) reacting 3,5-dihydroxybenzoic acid with acetic anhydride to form 3,5-diacetyloxybenzoic acid; (B) forming an amide compound from the 3,5-diacetyloxybenzoic acid by using ethyl chloroformate and an oleophilic group; and (C) hydrolyzing the acetyl group of the amide compound to provide a 3,5-dihydroxybenzoic acid derivative.
