Abstract
A cosmetic sampler has a thin dry layer of powder particles which are fragrance enhanced by fragrance containing microcapsules. The fragrance powder and microcapsules are applied as a production state, in a mass produced printed sampler manufacturing process from a liquid slurry which dries rapidly. The individual powder particles on the finished sampler item are raedily removed from the web surface by light finger pressure as a free flowing powder and the microcapsules are simultaneously ruptured to produce the desired fragrance.
