| abstract |
SPECIFIC The invention relates to novel polyanio-nics derived from aromatic ethers of polyglycerols responsive to regarding the general formula: (I) in which R denotes an aromatic or alkylaromatic radical that of valence z, containing from 6 to 18 carbon atoms, R 'de-signs a hydrogen atom, an aliphatic radical having from 1 to 16 carbon atoms or a phenyl radical, A denotes CH2 or CH2-O and in the latter case R 'is different from H, x denotes an integer or decimal from 1 to 8, y denotes a number integer or decimal from 1 to 20, z is an integer from 1 to 3, T denotes a hydrophilic group chosen from: and in proportions of 0% to 50% a nonionic group, M denoting an alkali metal, an ammonium group or a substituted ammonium group, and u denoting zero or 1. The compounds according to the invention can be used as tensio-active in various industries, especially in industry cosmetic. |
