Abstract

Methods of making personal care compositions including microcapsules and methods of enhancing the efficacy of the microcapsules in said personal care compositions.

First claim

What is claimed is:

1. An anhydrous stick antiperspirant composition, comprising:
a) an antiperspirant active selected from the group consisting of aluminum zirconium tetrachlorohydrex and aluminum zirconium trichlorhydrex, wherein the antiperspirant active has a concentration from 10% to about 35% by weight of the composition;
b) one or more anhydrous liquid carriers;
c) one or more structurants having a concentration from about 15% to about 25% by weight of the composition, wherein the one or more structurants comprises one or more waxes;
d) a non-ionic exthoxylated linear alcohol having a carbon chain length from about 20 to about 40; and
e) a fragrance delivery system comprising starch;
wherein the solid stick antiperspirant composition is a single phase.

2. The anhydrous stick of claim 1 , wherein the one or more anhydrous liquid carriers comprises a volatile silicone.

3. The anhydrous stick of claim 1 , wherein the anhydrous stick composition is a soft-solid antiperspirant or an invisible solid antiperspirant.

4. The anhydrous stick of claim 1 , wherein the starch comprises a raw starch, pregelatinized starch, modified starch, or combination thereof.

5. The anhydrous stick of claim 4 , wherein the modified starch is a corn starch.

6. The anhydrous stick of claim 5 , wherein the modified corn starch is an octenyl succinate.

7. The anhydrous stick of claim 6 , wherein the octenyl succinate comprises a substituted waxy corn starch.
