Abstract: Use of iminodiacetic acid derivs. of formula (I) as complexing agent or builder in technical cleaning compsns. for hard surfaces made of metal, plastic, lacquer or glass is new. R = H, 1-4C alkyl or CH2CH2X; Y = COOH, opt. as alkali metal or (substd.) ammonium salt; X is as Y or CONH2, opt. substd. on N. USE/ADVANTAGE - (I) can be included in a wide variety of cleaning compsns. e.g. rust removers; car wash compsns.; electrolytic defatting/derusting/descaling products; steel passivation compsns. high pressure cleaners, etc. Unlike known iminodiacetic acid derivs.; (I) can be formulated without organic solvents. They are extremely effective chelating agents for heavy and alkaline earth metals, esp. Ca. (I) are readily biodegradable and of low toxicity.

Abstract: A mixture of a long-chain unsaturated dimer or oligomer fatty acid and of a C6-C12 fatty acid is used as a solubilizer for non-ionic surface active agents in alkaline aqueous solutions.

Abstract: - 29 - O.Z. 0050/41484 Homopolymers and copolymers of monoethylenically unsaturated dicarboxylic acids of K 7 - 50 which are useful as additives in textile and dishwashing detergent compositions in amounts of from 0.1 to 15% by weight are obtained by free radical polymerization of (a) monoethylenically unsaturated dicarboxylic acids, (b) hydroxy-C2-C4-alkyl (meht)acrylates and optionally (c) other water-soluble monoethylenically unsaturated monomers at a degree of neutralization of the acid group-contain-ing monomers during the polymerization of from 52 to 70%, and contain not more than 1.5% by weight of unpolymerized dicarboxylic acid.
