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: The invention concerns the use as low-foam or antifoaming surfactants, in particular in washing and cleaning agent formulations and for chemical - technical applications, of block-form iso-tridecanolalkoxylates of the formula (I): R-O-(CmH2mO)x-(CnH2nO)y-H, in which: R designates an iso-tridecyl group; m stands for the number 2 and simultaneously n stands for 3 or 4; or m stands for the number 3 or 4 and simultaneously n stands for 2; and x and y, independently of each other, designate numbers from 1 to 20, wherein, if m = 2/n = 3 or 4, the variable x is greater than or equal to y.

Abstract: Use of iminodiacetic acid derivs. (I) as complexing agent or builder in alkaline cleaning formulations for the drinks and food industries is new. R=H, 1-4C alkyl, CH2CH2X, CH2CHOHX, -C(CH2OH)2X or CHY(-CH2)-nX; X= COOH (opt. as alkali metal or (substd.) ammonium salt) or CONH2 (opt. N substd.); Y = COOH (opt. in salt form as X); Z = H or OH; n = 1 or 2. Also new is an aq. cleaning formulation contg. 0.05-30 wt.% (I); 2-50 wt.% alkali metal hydroxide, carbonate and/or silicate, and 1-30 wt.% surfactant. USE/ADVANTAGE - The compsns. are used to clean bottles and machinery used in dairies, breweries or industries which mfr. and process preserved foods, baked goods, sugar, fat and meat. They give good results for removal of e.g. Ca salt deposits, hop resins, fat and dough residues etc. Unlike known iminodiacetic acid derivs., (I) can be formulated without organic solvents and also have an improved spectrum of activity. (I) are extraordinarily effective chelating agents for alkaline earth metals, e.g. Ca, and have extremely high Ca-binding capacity. They are readily biodegradable and have low toxicity.
