Abstract: The invention relates to the stabilization of alkaline solutions of peroxide bleaching compounds using, as stabilizing agent, a water-soluble poly-.alpha.-hydroxyacrylic acid salt which in the sodium salt form has an average molecular weight Mw from 2000 to 10,000 and to the preparation of such a salt.

Abstract: Process for the fatting and hydrophobizing of tanned leather and pelts, wherein the tanned leather or pelt is fatted with an aqueous dispersion containing a natural optionally chemically modified leather fatting agent and a surface-active phosphoric acid partial ester and optionally a nonionic and/or an anionic carboxy group and/or sulfo group containing surfactant and subsequently treating the fatted leather or pelt in aqueous medium with a plyvalent metal cation; the treated substrates and the dispersions suitable for carrying out the process.

Abstract: A water soluble or water dispersible composition containing(a) at least one phosphoric acid partial ester(b.sub.1) at least one mono- or di-(C.sub.2-3 alkylene) glycol mono-(C.sub.1-4 -alkyl) ether or at least one aliphatic C.sub.4-6 alcohol or a mixture thereof(b.sub.2) mono- or diethylene glycol or a mixture thereof(c) at least one aromatic-free or aromatic-poor hydrocarbon oil, and(d) a water miscible alkanolamine,the phosphoric acid partial ester (a) being dispersed or dissolved in the mixture (b.sub.1)+(b.sub.2)+(c), and component (a) being at least partially neutralized in salt form, with the proviso that the composition has a water content .ltoreq.5% by weight.It is useful as fatting agent for fatting leather.

Abstract: A method of fatting tanned leather substrates comprising(a) applying to the substrate as the fatting agent an aqueous solution or dispersion of an ortho-phosphoric acid partial ester having attached to the phosphorus atom an average 1 to 2 (which may be a non-integral number) groups of the formula I ##STR1## where each A independently is ##STR2## and n is a number from 2 to 10 with the proviso that 2 to 6 groups A are --(CH.sub.2).sub.2,R is an unsubstituted linear or branched (preferably linear) C.sub.14-20 alkyl group or an unsubstituted linear or branched (preferably linear) C.sub.14-20 alkenyl group,the phosphoric acid partial ester being in free acid or salt form;(b) treating with an agent selected from polyvalent metal oxide, hydroxide and salt, at the same time as fatting or after fatting.

Abstract: Process for the fatting and hydrophobizing of tanned leather and pelts, wherein the tanned leather or pelt is fatted with an aqueous dispersion containing a natural optionally chemically modified leather fatting agent and a surface-active phosphoric acid partial ester and optionally a non-ionic and/or an anionic carboxy group and/or sulfo group containing surfactant and subsequently treating the fatted leather or pelt in aqueous medium with a polyvalent metal cation; the treated substrates and the dispersions suitable for carrying out the process.

Abstract: 2-Hydroxy-n-propylamines of formula, ##STR1## in which R is a mono- or dialkylphenolpoly-(C.sub.2-3)-alkyleneglycolether group bound through an oxygen atom and containing at least 8 (C.sub.2-3)alkyleneoxy units of which at least 50% are ethyleneoxy, R.sub.1 is hydrogen or alkyl, optionally substituted with hydroxyl or X, R.sub.2 is alkylene, optionally substituted with hydroxyl, and X is an acid group, the compounds being in free acid or salt form, are useful as surface active agents, especially for use as dispersing or emulsifying agents in textile lubricant and fat liquor emulsions, and as agents for the degreasing of pelts and leathers, as tanning auxiliary agents and for the desizing of textile materials.
