abstract |
The invention relates to basic aluminium halogenide complexes obtained by reacting aluminium metal with hydrohalic acid and an organic acid. According to the invention, either the aluminium metal is dissolved in a mixture of hydrohalic acid and organic acid or the aluminium metal is first dissolved in the hydrohalic acid and the organic acid is then added. The basic aluminium halogenide complexes thus modified by the incorporation of ligands of organic acids exhibit an improved action as antiperspirant active ingredients. |
