Abstract
Abstract A unique system for distributing and sampling cosmetics is disclosed. The cosmetics which are normally dry, are combined with a liquid carrier and film forming agent and deposited onto a substrate. The film forming agent acts to microencapsulate the cosmetic and lightly bond the cosmetic to the substrate. When the film forming agent dries, it protects the cosmetic. Thus, the cosmetic can be applied to a substrate and covered with a paperboard sheet. Access to the cosmetic can be provided by a tear strip. Greasy cosmetics, such as lipstick, can also be applied to a substrate according to the present invention. These cosmetics are first microencapsulated with gelatin and the formed microparticles are secondarily encapsulated with a film forming agent and deposited onto a substrate. This method permits cosmetics to be distributed through the mail and as magazine inserts and the like.
