Abstract: An edible composition comprising peptides rich in tryptophan, which edible composition further comprises a rapidly available glucose composition and a slowly available glucose composition.

Abstract: Water-softening formulations which comprise:(a) a biodegradable copolymer;(b) an inorganic water-softening silicate; and, optionally,(c) another inorganic salt;(d) a dispersing and complexing agent; and(e) a surfactant and also additional customary additives have improved biodegradability.

Abstract: The present invention relates to detergent formulations which contain(a) 3 to 70% by weight of one or more surfactants;(b) 1 to 60% by weight of a readily biodegradable copolymer which comprises monomer units obtained from(A) monoethylenically unsaturated dicarboxylic acids, anhydrides, salts thereof or mixtures thereof,(B) monoethylenically unsaturated monocarboxylic acids, salts thereof or mixtures thereof,(C) monounsaturated monomers which aqueous polymerization, after hydrolysis or saponification, give monomer units which have one or more free hydroxyl groups on a carbon chain of the copolymer, and(D) 0 to 15% by weight of one or more further monomers capable of free radical copolymerization;(c) 0 to 60% by weight of washing alkalis; and(d) 0 to 70% by weight of standardizing agents,and their use in inhibiting incrustation of textiles and in removing alkaline earth metals from textiles during laundering.

Abstract: Low-foaming, liquid or pulverulent machine detergents today consist, in the surfactant portion, mainly of surfactants based on petrochemicals; the biodegradability and ecotoxicity frequently does not reach the level of surfactants based on natural materials. Accordingly, a surfactant combination for low-foaming machine detergents is proposed, which is predominantly prepared from renewable raw materials; washing results and biodegradability are excellent. The surfactant portion of these machine detergents consists of fatty alcohol ethoxylates, soaps and alkyl polyglycosides which consist at least of a mixture of alkylglycosides of varying chain length and varying degrees of glycosylation.

Abstract: N-oxalkylated derivatives of aniline of the formula ##STR1## wherein R.sub.1 and R.sub.2 each independently is hydrogen, NH.sub.2, or lower alkyl;R.sub.3 is hydrogen or lower alkyl,R.sub.4 is hydrogen or methyl, andn is a number from 1.0 to 5.0,are useful as polymer-dissolving components in floor cleaners.
