Title:
DISPERSIONS OF A SOLID IN AN AQUEOUS LIQUID INCLUDING A POLYALKYLENEGLYCOL ESTER OR AMIDE OF A FATTY ACID DIMER AND/OR TRIMER
Document Type and Number:
WIPO Patent Application WO2003106010
Kind Code:
A8
Abstract:
Polyethylene glycol esters and amides of polymerised fatty acids are useful dispersing agents for solids, particularly particulate solids e.g. agrochemicals, oil drilling mud components, pigments, personal care formulants, ceramics, magnetic materials, extenders, fillers, optical brighteners, textile auxiliaries, or soil removed from clothes during cleaning, in aqueous media. Particular such agents are of the formula (I): [Pol]-(COX)m (I), where: Pol is the core residue of a polymerised fatty acid; m is 2 or 3; and each X is: OM; where M is H, a cationic salt forming species or a group -(AO)nR<7>; or a group -NR<8>-(AO)nR<9>; where AO is an alkylene oxide residue; n is from 1 to 100; and R<7>, R<8> and R<9> are as defined, from H, an anionic group, alkyl or alkenyl; provided that at least one X is a group of the formula -(AO)nR<7> or -NR<8>-(AO)nR<9>.
