ABSTRACT:
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 R4of formula —CH2—C(Ph) (RB)—R5-Ph in which RBrepresents H or methyl and R5represents 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 R4or an alkyl, cycloalkyl or aralkyl alcohol.
