Abstract
The invention relates to a composition comprising a mixture of C3-C22 alcohol alkoxylates which have a narrow weight distribution and are capped in the terminal portion by a group chosen from linear or branched alkyls comprising between 1 and 6 carbon atoms, the phenyl group, benzyl group and hydrocarbon groups having a carboxy function —COO—, and groups having a sugar unit. The invention also relates to the method for preparing said composition and to the uses thereof as a surfactant, in particular as a surfactant with low foaming power.
Claims14
A composition comprising a mixture of end-capped alcohol alkoxylates, wherein:
- the alcohol comprises from 3 to 22 carbon atoms,
- the weight distribution of the alkoxylates follows a monomodal distribution, the peak width value (2σ) of which is less than 7, and
- an end part is capped by a group chosen from linear or branched alkyls comprising from 1 to 6 carbon atoms, a phenyl group, a benzyl group, hydrocarbon groups carrying a carboxy —COO— functional group, and groups carrying a sugar unit.
