<p>A heterocyclic aluminum compound of the formula (CH2)n--O Z ANGLE ANGLE Al-Cl (CH2)n--O wherein n is 1 or 2. When n is 1, Z is -CH=CH-. When n is 2, Z is either -(CH2)m wherein m is 0-6, or a heteroatom selected from -O-, -S-, >SO, >SO2 or >N-COR' where R' is an aliphatic hydrocarbon of 1-17 carbon atoms, -(CH2)q-C6H5 where q is 0 or 1, styryl, diphenyl methyl or phenyl optionally substituted by chlorine, fluorine, methyl and alkoxy having 1-4 carbon atoms. The compound can be prepared by reacting isopropyl aluminate with an omega -diol of the formula (CH2)n-OH Z ANGLE (CH2)n-OH wherein Z has the meaning given above and then reacting the resulting product with dry HCl or an acyl chloride of the formula R'-COCl wherein R' has the meaning given above. The heterocyclic aluminum compound exhibits antiperspirant activity. It can be used in cosmetic antiperspirant compositions comprising a cosmetic vehicle and about 0.2-30 weight percent thereof based on the weight of said composition.</p> |
