Man löst z. B. xo kg Pflanzenlecithin in 5o bis 6o kg Wasser bei gewöhnlicher Temperatur oder unter Erwärmen auf 6o bis 7o° C auf und reibt das vorher z. B. chromgegerbte Leder mit dieser Lösung ein.One solves z. B. xo kg of plant lecithin in 50 to 60 kg of water with ordinary Temperature or with heating to 6o to 7o ° C and rub the previously z.

An Stelle von Pflanzenlecithin kann auch tierisches Lecithin für den gleichen Zweck Verwendung finden, z. B. solches, das aus Fischrogen gewonnen wird.Instead of plant lecithin, animal lecithin can also be used for the find the same purpose, e.g. B. those obtained from fish roe.

Die Lecithinlösung läßt sich nicht allein als Ersatz für Eigelb verwenden, sondern eignet sich auch für viele Zwecke, für welche bei der Lederbehandlung seither sulfonierte Öle Verwendung fanden.The lecithin solution cannot be used alone as a substitute for egg yolk, but is also suitable for many purposes, some of which have been used in leather treatment since then sulfonated oils were used.
