Abstract
Compositions comprising PA1 (a) phosphoric acid partial esters of oxyalkylated C.sub.14-20 -fatty alcohols and PA1 (b) phosphoric acid partial esters of non-oxyalkylated C.sub.12-20 -fatty alcohols optionally together with PA1 (c) a hydrophilic non-ionic or anionic surfactant different from (a) a (b) PA1 but essentially free of optionally chemically modified natural leather-fatting agents are excellently suitable for the softening and fatting of leather without admixture of optionally chemically modified natural leather fatting agents.
