摘要：
Anhydrous antiperspirant compositions comprising particulate antiperspirant active； capsules comprising a shear-sensitive shell which encapsulates perfume； and a carrier for the particulate antiperspirant active and capsules； wherein the capsules have a shell of cross-linked gelatin coacervate having a thickness of from 0.25 to 9 μm and providing from 10 to 40% by weight of the capsules, a volume average particle diameter of from 25 to 70 μm, a ratio of shell thickness to the average particle diameter in the range of from 1:5 to 1:120, and a Hysitron hardness in the range of from 1.5 MPa to 50 MPa.
