Patent GB-459039-A (GB)
Title: Manufacture of washing agents and detergents
IPC: A61Q11/00
Filed: 1935-03-25
Abstract: Washing-agents, suitable for use in the cleaning of textiles and in the preparation of tooth pastes and hair washes, are made by rendering neutral or acid, by means of a compound of acid reaction, a water-soluble salt of an aliphatic carboxylic acid containing an aliphatic radical of high molecular weight which is linked to the carboxyl group through at least one nitrogen atom, but not through an oxygen atom.  Specified salts are the alkali salts of octadecylenylaminoacetic acid, of oleyl sarcoside, and of coconut fatty acid sarcoside, and specified compounds of acid reaction are sodium bisulphite, sodium bisulphate, and boric, citric, tartaric and oxalic acids.  According to examples: (1) a liquid hair wash contains water, citric acid and the sodium salt of coconut oil fatty acid sarcoside; (2) a preparation for removing copying ink stains contains water, isopropyl-alcohol, citric acid and the sodium salt of coconut fatty acid sarcoside; (3) a hair wash powder contains sodium bisulphate, sodium chloride and the sodium salt of coconut oil fatty acid sarcoside; (4) a hair wash contains tartaric acid and the sodium salt of coconut oil fatty acid sarcoside.  According to the Specification as open to inspection under Sect. 91 the sodium salt of dodecylamino-acetic acid, the reaction product of octadecenylmethylamine on citric acid, and water-soluble salts of aliphatic carboxylic acids of high molecular weight, in which there is at least one nitrogen atom between the carboxyl group and the aliphatic radical may be used, but this subject-matter does not appear in the Specification as accepted.ALSO:Washing agents, suitable for use in the cleaning of textiles and in the preparation of tooth pastes and hair washes, are made by rendering neutral or acid, by means of a compound of acid reaction, a water-soluble salt of an aliphatic carboxylic acid containing an aliphatic radical of high molecular weight which is linked to the carboxyl group through at least one nitrogen atom, but not through an oxygen atom.
