Antiperspirant compositions
View Patent ↗What is described herein is an antiperspirant composition including an active antiperspirant ingredient, and a phenylethyl, benzyl or substituted benzyl ester as additive therein, which is an aryl carboxylic ester of 2-phenylethyl alcohol, 1-phenylethyl alcohol or benzyl alcohol, which leaves a reduced visible white chalky residue on the skin of the user.
1. An antiperspirant composition comprising
(a) an active antiperspirant ingredient, and
(b) an aryl carboxylic ester of 2-phenylethyl alcohol, as additive therein, which leaves a reduced visible white chalky residue on the skin of the user.
2. A composition according to claim 1 wherein said phenylethyl ester is 2-phenylethyl benzoate.
3. A composition according to claim 1 in the form of an antiperspirant stick, lotion, cream, roll-on, solution or aerosol.
4. A composition according to claim 1 wherein said active antiperspirant ingredient is an inorganic salt or organic compound.
5. A composition according to claim 4 wherein said inorganic salt or organic compound is an aluminum, zirconium or zinc salt, or mixtures thereof.
6. A composition according to claim 5 wherein said antiperspirant ingredient is a coordination complex of aluminum zirconium tetrachlorohydrate and glycine.
7. A composition according to claim 5 wherein said inorganic compound is aluminum chlorohydrate.
8. A composition according to claim 1 wherein the refractive index of (b) therein substantially matches the refractive index of the white, chalky residue formed after use thereby reducing the visible white, chalky residue on the skin of the user.
9. A composition according to claim 8 wherein the refractive index value of said 2-phenylethyl benzoate is about 1.5.
