Abstract
The present invention relates to an algal adduct of the citrullinylarginine natural dipeptide as well as to its dermatological use and the use of chemical analogs issued from the same dipeptide displaying no toxic potential, as skin and phanera care and treatment agents, the said analogs having the following general formula (I) 1 in which: R1 represents an acyl or acycloxy radical, R2 represents a hydroxyl, amine, alkylamine or alcoxy radical, R3 represents a hydrogen atom or a hydroxyl radical.
Claims19
Seaweed extract, notably from red macroalgae, characterized in that it is likely to be obtained through a process including the following steps:
- extraction of said algae with the help of a solvent or a solvent mixture acceptable in pharmacy,
- enhancement of the weight amount of intrinsic polypeptides or proteins up to a total content equal to at least 20%,
- eventually incorporation of a titrated content of citrullinylarginine dipeptide obtained by chemical way,
- a treatment in hot of the resulting extract.
Use of analogs of citrullinylarginine natural dipeptide, or one of any of their salts, as skin and phanera care and treatment agents, the said analogs having the following general formula (I):
- 5
- in which:
- R1 represents an acyl or acycloxy radical,
- R2 represents a hydroxyl, amine, alkylamine or alcoxy radical,
- R3 represents a hydrogen atom or a hydroxyl radical.
