ROLL-ON APPLICATION OF AQUEOUS MICROENCAPSULATED PRODUCTS Abstract A material (14) such as an antiperspirant con- tained in a shear-sensitive, free-flowing, powdery, sus- pension of aqueous droplets stabilized by a barrier of very fine, hydrophobic metal oxide is dispensed from a roll-on applicator. As the ball (18) is rotated, an adher- ent film (22) of the suspension passes through the annular outlet (20) and is subjected to shear forces. The suspension coalesces into a film (24) of cream or lotion. The sus- pension exhibits excellent flowability through the outlet (20) without any binding or fouling and the lotion or cream film has good adhesion to the ball. Application results in a dry feeling on the skin of the subject, a short dry-out time and excellent antiperspirant efficacy.
