The invention relates to the use of grafted polymers as greying inhibitors during the washing and aftertreatment of textile goods. Said polymers are obtained by polymerising A) 10 to 95 wt. % of grafted monomers containing, in relation to A), a) 1 to 99 wt. % of at least one vinyl ester, b) 1 to 99 wt. % of at least one N-vinyl lactam, c) 0 to 90 wt. % of at least one other monoethylenically unsaturated monomer which can be copolymerized with monomers a) and b), and d) 0 to 5 wt. % of at least one monomer having at least two ethylenically unsaturated, non-conjugated double bonds in the molecule, in the presence of A) 5 to 90 wt. % of at least one polymer B), chosen from polyalkylene oxides containing at least 3 units of a Cto Calkylene oxide, and polytetrahydrofuranes containing at least 3 units of tetramethyl oxide units, and the mixtures thereof.

Use of grafted polyalkylene oxides as greying inhibitors when washing

The invention relates to the use of cationically-modified, particle-shaped, hydrophobic polymers as addition agents in rinsing, care, detergent, and cleaning products. The surface of said polymers is cationically modified by means of a coating of cationic polymers and the particle size of said polymers ranges from 10 nm to 100 &#x3bc;m.

Use of cationically modified, particle-shaped, hydrophobic polymers as addition agents in textile rinsing or care products and as addition agents in detergents

Hydrophilic, open-cell, elastic foams with a melamine/formaldehyde resin base, production thereof and use thereof in hygiene products

Polymers that contain alcoxylated, condensed alkaline amino acids and method of producing said polymers

Paper, board and cardboard are produced by a process in which a paper stock is drained in the presence of condensates of basic amino acids with sheet formation. In particular, homo- and cocondensates of lysine and the crosslinked condensates obtainable therefrom by reaction with crosslinking agents are used in amounts of from 0.01 to 5% by weight, based on dry paper stock, as a means of increasing the dry and wet strength and the absorptivity of paper, for fixing anionic dyes and interfering substances in the paper, for increasing the drainage rate and the retention as well as the efficiency of synthetic anionic and cationic retention aids in the production of paper, board and cardboard by draining a paper stock with sheet formation.

Method of producing paper, paperboard and cardboard

Modified polyaspartic acids are obtained by polycondensing (a) 1 to 99.9 mol % aspartic acid with (b) 99 to 0.1 mol % fatty acids, polybasic carboxylic acids, anhydrides of polybasic carboxylic acids, polybasic hydroxycarboxylic acids, monobasic poly-hydroxycarboxylic acids, alcohols, amines, alkoxylated alcohols and amines, amino sugars, carbohydrates, sugar carboxylic acids and/or non-proteinogenic aminocarboxylic acids, or by polymerizing monoethylenically unsaturated monomers in the presence of polyaspartic acids, in the manner of radically initiated graft copolymerization. Also disclosed is a process for preparing these modified polyaspartic acids, as well as the use of these modified polyaspartic acids as additives to washing and cleaning agents, as water conditioning agents and as deposit inhibitors during the condensation of sugar juice.

Laundry detergent compositions with amino acid based polymers to provide appearance and integrity benefits to fabrics laundered therewith

Compositions than contain from about 1% to about 80% by weight of surfactants selected from the group consisting of nonionic, anionic, cationic, amphoteric or zwitteronic surfactants, or mixtures thereof; and from about 0.1% to about 10%, by weight of a mixture of amino acid based polymers, oligomers or copolymers of the general formula (I) wherein the polymer, oligomer, or copolymer contains at least about 5 mole % of one or more amino acids and an organic acid are disclosed. The compositions are useful as fabric treatment agents as they can impart fabric appearance and integrity benefits to fabrics.

An amino acid based polymer, oligomer or copolymer containing at least 5 mol % of units of a basic amino acid selected from the group consisting of lysine, argenine, ortnithine, trgptophane and mixtures thereof and at least about 5 mol % of a polymerizable compound selected from the group consisting of aliphatic or cycloaliphatic amines, alicyclic amines, diamines, triamines, tetraamines, aliphatic amino alcohols or mixtures thereof, an a process for the production of the said polymer, oligomer or copolymer by condensing at a temperature of at least 120.degree. C. said basic amino acid with at least one of said polymerizable compounds.
