Abstract: 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 ?m and providing from 10 to 40% by weight of the capsules, a volume average particle diameter of from 25 to 70 ?m, 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.

Abstract: Anhydrous antiperspirant compositions containing an encapsulated fragrance, in which the encapsulate shell comprises an aminoplast resin, and preferably a melamine/formaldehyde resin. The encapsulates have a weight average particle diameter in the range of 25 to 60 ?m, a shell having a measured thickness in the range of from 1 to 10 ?m and an average in the range of from 5 to 8 ?m, a ratio of the shell thickness to the average particle diameter in the range of from 1:5 to 1:10 and a Hysitron hardness in the range of from 2 MPa to 50 MPa, particularly 15 to 25 MPa, enabling them do be advantageously employed in the anhydrous antiperspirant compositions.

Abstract: It is desirable for antiperspirant or deodorant roll-on compositions to be able to deliver fragrance over an extended period of time after application, but previously contemplated encapsulates were based on starch or similar water-soluble or dispersible shell materials, rendering them ineffective in aqueous emulsions. Capsules of fragrances in cross-linked coacervated gelatin shells satisfying defined particle size, shell thickness and hardness criteria enable roll-on compositions to be incorporated into aqueous antiperspirant or deodorant compositions encapsulated fragrance that can be released after the composition has been topically applied to skin.
