Antiperspirant compositions containing suspended antiperspirant actives in a water-immiscible carrier leave visible deposits on skin or clothing unless the actives are masked. The carrier mixture in compositions herein comprise an alkylsiloxane which is substituted by a group R.sup.4 of formula --CH.sub.2--C(Ph) (R.sup.B)--R.sup.5-Ph in which R.sup.B represents H or methyl and R.sup.5 represents an alkylene group containing 0 to 3 carbons, and in which the proportion of aryl carbon atoms is at least 60% of all carbon atoms in the molecule. Preferably, the substituent comprises diphenylethyl. Optionally, the siloxane can be capped by the residue of a substituted vinyl group other than R.sup.4 or an alkyl, cycloalkyl or aralkyl alcohol.
