Abstract: Compositions for changing the color of hair by the action (direct or indirect) of compounds therein which release nascent oxygen, do less harm to the hair when they have a content of a water-soluble 3-amino-1-hydroxypropane-1,1-diphosphonic compound. The compound can be in free acid or water-soluble salt or partial ester form. Hair which is pre-treated with one of the mentioned diphosphonic compounds is at least partially protected against the action of nascent oxygen.

Abstract: An improvement in the process of setting hair comprising applying a film of a vinyl acetate copolymerizate consisting essentially of(a) from 65% to 80% by weight of vinyl acetate units,(b) from 10% to 20% by weight of units of a maleic acid diester with a straight-chained alkanol-1 having from about 8 to 10 carbon atoms,(c) from 5% to 20% by weight of units of a mono-olefinically unsaturated ester having from 6 to 8 carbon atoms and a hydrophilic group, and(d) from 3% to 10%, particularly 7%, by weight of crotonic acid and salts thereof,To the hair after setting the same; and hair setting agents in the form of hair sprays and setting lotions containing up to 10% by weight of said vinyl acetate copolymerizate and/or salts thereof.

Abstract: A process of suppressing body odor comprising applying a substantially anhydrous cosmetic preparation for suppressing body odor containing as a deodorant an ester of citric acid or acetylcitric acid with an aliphatic alcohol having from 1 to 6 carbon atoms or an alicyclic alcohol having 5 to 6 atoms.

Abstract: A process of suppressing body odors comprising applying a substantially anhydrous cosmetic preparation for supressing body odor containing as a deodorant an ester of an aliphatic mono- or di-hydroxycarboxylic acid or an aliphatic mono- or di-hydroxy-dicarboxylic acid having from 2 to 4 carbon atoms with an aliphatic alcohol having from 1 to 6 carbon atoms, or an alicyclic alcohol having 5 to 6 carbon atoms.
