Use of polyelectrolyte complexes in antiperspirant technology

摘要

Polyelectrolyte complexes between cationic polymers and anionic polymers are used in antiperspirant compositions containing an active antiperspirant ingredient.

主权项

1. An antiperspirant microgel comprising:
a) an active antiperspirant ingredient selected from the group consisting of titanium dioxide or zinc oxide and b) a polyelectrolyte complex comprising
(i) polyquaternium-28(ii) polyvinylmethyl/maleic acid copolymerwherein the charge ratio of (i):(ii) is from about 0.70 to about 1.80; and wherein the microgel has an average particle size sufficient to allow the antiperspirant microgel to enter a human sweat gland pore and form a polymeric plug therein, wherein the antiperspirant microgel has an antiperspirant effect.
