Abstract

The invention relates to the use of mixtures of polymers comprising amine groups and polymers comprising amide groups for modifying the rheology of compositions comprising water, and to rheology modifying methods. In particular, the invention relates to the use of these mixtures for the thickening of compositions comprising water for cosmetic, human and animal nutrition, dermatology, pharmacy and detergents and cleaners, crop protection, surface modification and during petroleum production, such as, for example, enhanced oil recovery.
