Abstract: Processes for the treatment of textiles, fur, leather, and other fibrous materials are conducted with or in the presence of soluble salts of aromatic compounds in which the aromatic nucleus is substituted by an aliphatic radicle containing four or more carbon atoms and is connected directly by a sulphur or nitrogen atom to a radicle containing a carboxylic group.  These compounds have wetting, emulsifying, foam producing, cleansing and stabilizing properties and may be used in admixture with alkali carbonate, sodium ortho-, pyro-, poly-, meta- or hypophosphates, sodium silicates, alkali borates, sodium sulphate, sodium naphthalenesulphonate, alkali per salts, e.g. perpyrophosphates, soaps, oleylmethyl taurin, solvents such as benzine, benzene, the lower and higher alcohols, cyclohexanol, cyclohexanone, glycolmonoethylether, glyceroldimethylether, glycerolmonocyclohexylether, 2 : 2 - pentamethylene-4-oxymethyl dihydrodioxol, wool fat, urease, pancreation, and p-chlor-m-cresol. The compounds may be derived from alkylized thiophenols and thionaphthols and alkylized aromatic amines, the residue containing a carboxylic group being introduced for example by reaction with alkali salts of halogenated carboxylic acids. Thus hexyl thiophenol, p-sec.-heptyl-o-thio cresol, or 1 : 4-sec. butylthionaphthol may be reacted with chlor acetic, propionic or benzoic acids or with bromsuccinic acid with the formation of sulphide groups.  The aromatic nucleus may also be connected to the carboxylic residue by means of a sulphone, amine or carboxyamido group.  Instead of carboxylic acids, esters, amides or nitriles may be condensed with the alkylized compounds, and the products saponified.  Salts of the compounds with triethanolamine, aminopropandiol and tetraethylammonium hydroxide are mentioned.ALSO:Soluble salts of aromatic compounds in which the aromatic nucleus is substituted by an aliphatic radicle containing four or more carbon atoms and is connected directly by a sulphur or nitrogen atom to a radicle containing a carboxylic group are stated to have emulsifying properties and may be used in admixture with alkali carbonate, sodium ortho-, pyro-, poly-, meta- or hypophosphates, sodium silicates, alkali borates, sodium sulphate, sodium naphthalene sulphonate, alkali per salts, e.g. perpyrophosphates, soaps, oleylmethyl taurin, solvents such as benzine, benzene, the lower and higher alcohols, cyclohexanol, cyclohexanone, glycolmonoethylether, glyceroldimethylether, glycerolmonocyclohexylether, 2 : 2-pentamethylene-4-oxymethyldihydrodioxol, wool fat, urease, pancreatin, and p-chlor-m-cresol.  The compounds may be derived from alkylized thiophenols and thionaphthols and alkylized aromatic amines, the residue containing a carboxylic group being introduced for example by reaction with alkali salts of halogenated carboxylic acids.  Thus hexylthiophenol, p-sec-heptyl-o-thiocresol, or 1 : 4-sec. butylthionaphthol may be reacted with chloracetic, propionic or benzoic acids or with bromsuccinic acid with the formation of sulphide groups.  The aromatic nucleus may also be connected to the carboxylic residue by means of a sulphone, amine or carboxyamido group.
