European Patent EP2377848
Publication date: Oct. 2, 2013
Assignee: NOF Corp.
Amino acids have reportedly been used widely as cosmetic raw materials as they are excellent in biocompatibility and environmental compatibility. Many attempts at derivatization have been made to further these functionalities. Among major amino acids, arginine has a guanidinyl group that is excellent for absorption into the skin and hair, so various arginine derivatives have been developed.The present invention relates to a novel arginine derivative, a process for producing the same and a cosmetic containing it. This novel derivative has excellent skin softening effects and skin-conditioning effects, and its feel during use is satisfactory, with minimal sticky or tense feel. Furthermore, its production process suppresses the generation of impurities resulting from side reactions.
