Abstract: This invention relates to liquid concentrated aqueous solutions of salts of alkyl ether carboxylic acid derived from alkanols having at least 10 C atoms, which aqueous solution of the salts of alkyl ether carboxylic acid also contains ethoxylated or ethoxylated and carboxymethylated products or mixtures thereof, derived from polyhydric alcohols, the degree of ethoxylation of those products being at least 0.5. The invention also relates to processes for preparing such liquid aqueous solutions.

Abstract: The invention relates to mixtures of amidated fatty acids or derivatives thereof of the general formula ##STR1## wherein R' is absent or an alkyl group with 2-4 C-atoms, the average value of n is 0,5 to 3 and R represents a fatty acid radical with 14-24 C-atoms obtained from oils produced from the plant species `Brassica` with an eruca acid content lower than 5%.These products are good thickeners for surfactants and/or detergents. No nitrose compounds of (di)alkanolamines, which could present a health hazard, are formed in the thickeners according to the invention.

Abstract: Novel surfactant compounds are provided of the formula R--CO--NH--(C.sub.2 H.sub.4 O).sub.n --CH.sub.2 COOH, wherein R--CO-- is the residue of at least one aliphatic carboxylic acid of 6-22 carbon atoms and n represents a number having an average of 2-10, as well as their salts with alkali metals, ammonium and amines. These compounds possess not only a low primary toxicity, but also a low secondary toxicity for the skin, and accordingly they are especially useful in cosmetic compositions, compositions for non-automatic dishwashing and laundering compositions for the fine laundry.

Abstract: The invention relates to a process for the preparation of a detergent containing one or more compounds having the formula RCONH(C.sub.2 H.sub.4 O).sub.n CH.sub.2 COOH, salts and glycerol, ethoxylated glycerol, carboxymethylated glycerol, or carboxymethyl ethoxylated glycerol and mixture thereof, where R represents a linear or branched aliphatic hydrocarbon group with 5-21 carbon atoms and n is a number from 1-20, by amidating, ethoxylating and carboxymethylating one or more fatty acids having the formula RCOOH and, if so desired, converting all or part of the ether carboxylic acid obtained to a salt thereof, characterized in that an oil or fat is started from and that this oil or fat is aminolyzed in the presence of an alkali(ne earth) metal and the reaction mixture obtained is in the usual manner ethoxylated, carboxymethylated and, if desired, converted in whole or in part to a salt.

Abstract: A method of manufacturing twistless or substantially twistless yarn consisting of dry drafting a sliver, moistening the drafted sliver with a water-soluble cation-active polymer bonding agent, drafting the sliver in the web state, false twisting the sliver, activating the bonding agent by drying the sliver on a heated drum and winding the resultant yarn up on cross wound cheeses, and a yarn manufactured according to this process.

Abstract: A detergent composition is provided containing as essential ingredients one or more surfactants, one or more builders, perborate, and a member of the group chosen from (a) acidic substances acceptable in detergent compositions and having a pK value of at least 2, and (b) compounds which in aqueous solutions of said compositions form said substance in situ, a 0.5% aqueous solution of said composition having an initial pH of 5.0-8.5, measured at room temperature.The composition may contain further usual additives, and is preferably substantially phosphate-free. Surfactants of the polyether-carboxylic acid type may be used herein advantageously.

Abstract: Stable concentrated aqueous solutions of glycidyltrimethylammonium chloride are provided which contain the monohydrate of glycidyltrimethylammonium chloride in a concentration of 90% to saturation, said solutions after dilution with water to a content of 25% glycidyltrimethylammonium chloride showing a pH of less than 12.5. Furthermore a process is provided for preparing stable concentrated solutions of glycidyltrimethylammonium chloride, wherein anhydrous glycidyltrimethylammonium chloride is mixed with an excess of water over the amount necessary for forming the desired solution, whereafter the excess of water is evaporated under reduced pressure. Also the invention provides the monohydrate of glycidyltrimethylammonium chloride as a novel substance.
