Abstract
Hair-treatment preparations containing as additive at least one surface-active phosphonic acid corresponding to general formula I, II or III below ##STR1## in which R.sup.1 represents a C.sub.5 -C.sub.21 alkyl, R.sup.2 represents hydrogen or --PO.sub.3 H.sub.2, and R.sup.3 represents hydrogen, hydroxyl, or, if R.sup.2 is --PO.sub.3 H.sub.2, --NH.sub.2, and R.sup.4 represents hydrogen or a lower alkyl group containing from 1 to 4 carbon atoms, or a water-soluble salt thereof, improved the wet combability of hair and reduce its tendency to develop static charges. Octane-1-phosphonic acid, decane-1-phosphonic acid and dodecane-1-phosphonic acid or their salts are particularly effective. The phophonic acids are used in quantities of from 0.05 to 10% by weight, and preferably in quantities of from 0.1 to 2.0% by weight together with anionic tensides.
