FIELD: chemistry.

SUBSTANCE: present invention relates to sulphated esters of oligo-hydroxycarboxylic acids, cosmetic and pharmaceutical products that contain these esters, and the use of these esters as anionic surfactants. Invention relates to a compound of general formula (I), where R¹ represents hydrogen or a linear or branched aliphatic hydrocarbon residue having from 1 to 30 carbon atoms and 0, 1, 2 or 3 double bonds, residues R² are independently selected from hydrogen, methyl, ethyl, -OA, -COOR⁴, -CH₂-OA and -CH₂-COOR⁴, wherein the residues R⁴ are hydrogen or a linear or branched aliphatic hydrocarbon residue having from 1 to 30 carbon atoms and 0, 1, 2 or 3 double bonds, residues R³ are independently selected from hydrogen, methyl, ethyl, -OA, -COOR⁵, -CH₂-OA and -CH₂-COOR⁵, wherein the residues R⁵ represent hydrogen or a linear or branched aliphatic hydrocarbon residue having from 1 to 30 carbon atoms and 0, 1, 2 or 3 double bonds, A represents H or -SO₃B, where B is hydrogen or a cation equivalent, n is on average a value of at least 0.1, m1 and m2 are independently 0 or 1, provided that at least one of the A residues is -SO₃B, and provided that at least one of the residues R¹, R⁴ or R⁵ represents a linear or branched aliphatic hydrocarbon residue having from 1 to 30 carbon atoms and 0, 1, 2 or 3 double bonds. .

EFFECT: sulphated oligo-hydroxycarboxylic acids esters and use thereof are disclosed.
