Abstract
A method of adhering a cosmetic pressed powder product or a stick type applicative product (e.g. a lipstick) inside a receptacle therefor is disclosed. The receptacle comprises a casing having a top end and a base end with a receiving base member disposed at the base end, and the receiving base member has an inner surface. The base member may be designed or adapted to be moveable inside the casing to advance and retract the product. The method comprises applying a silicone hot melt adhesive composition in liquid form to at least part of the inner surface of the receiving base member; inserting the product into the receiving base member on or in the silicone hot melt adhesive composition while still in liquid form; and cooling, and optionally curing, the silicone hot melt adhesive to adhere the product inside the receptacle. Retained-products formed via the method are also disclosed.
