Abstract

Official abstract text for this publication.

The invention pertains to the field of aqueous thickening compositions, particularly for increasing the viscosity of an aqueous paint or varnish composition, a detergent composition or a cosmetic composition, in particular a cosmetic composition comprising ethoxylated surfactant compounds. The composition according to the invention comprises at least 40% by weight of water and combines a particular thickening compound and a nonionic compound comprising at least one hydrophilic saccharide group attached to at least one linear or branched hydrophobic chain.
