Abstract
The invention concerns in particular a composition for a softening lotion used in fiber treatment. In the invention, the lotion composition is aqueous and liquid at a temperature of at least 5° C. and comprises, as active substances: (a) one or more saturated linear fatty alcohols having at least 16 carbon atoms, and (b) one or more waxy esters having a total of at least 24 carbon atoms. The application of the invention is to the manufacture of fibrous products such as disposable absorbent paper products.
