摘要 |
The agent for skin external use of the present invention contains (A) tocopherol glycine esters, (B) ascorbic acid-2-phosphoric acid esters and a specific amount of (C) an anionic surface active agent having a lipopeptide structure. According to the agent for skin external use (including a cosmetic) of the present invention, it is possible to enhance stability of the tocopherol glycine esters in spite that the tocopherol glycine esters and the ascorbic acids are contained simultaneously, so that occurrence of coloring (including turbidity) and/or precipitation with time can be prevented. Therefore, efficacy and effects of the agent or the cosmetic can be well exerted over a long period of time.
