Claims13
A method of providing surfactant properties to a cosmetic or pharmaceutical composition, said method comprising using in said cosmetic or pharmaceutical composition a compound of formula (I):
- ##STR4## in which:
- R.sub.1 represents a linear or branched, saturated or unsaturated alkyl radical having 4 to 6 carbon atoms,
- R.sub.2 represents a linear or branched, saturated or unsaturated alkyl radical having 2 to 4 carbon atoms,
- R.sub.3 represents a hydrogen atom or a linear or branched, saturated or unsaturated alkyl radical having 1 to 6 carbon atoms, and
- A represents a radical of the formula:
- --(CH.sub.2).sub.n --(CHOH).sub.m --Z
- in which n is an integer equal to 0 or 1, m is an integer ranging from 0 to 4, and Z is a hydroxylated alkyl radical having from 1 to 4 carbon atoms,
- wherein said compound of formula (I) provides surfactant properties to said cosmetic or pharmaceutical composition.
