The invention concerns anti-transpirants containing water-soluble inorganic astringent anti-perspirant substances, e.g. aluminum hydroxychloride. Such anti-perspirants can be produced as stable, fine oil-in-water emulsions with a droplet diameter of 100-300 nm and having a water content of 40-80 wt.% by emulsifying the oil component by the phase-inversion technique, using 0.1-0.3 parts by wt. of a non-ionic emulsifier with an HLB value of 10-15 plus 0.1-0.3 parts by wt. of a coemulsifier of the saturated fatty alcohol or polyol fatty-acid partial-ester type for each part by wt. of the oil component. The anti-perspirants proposed may also contain 1-20 wt.% of a water-soluble polyol with 2-8 C-atoms and 2-6 hydroxyl groups and are preferably free of lower alcohols having 2-3 C-atoms. |
