Abstract: A cleansing cosmetic composition comprising; i) a cationized silicon delivery system selected from one or more of a) a cationized fatty alkyl silicone copolymer; b) a cationized dimethiconol complex and c) a cationized high viscosity lower alkyl silicone fluid with or without cationized silicone gum blend; and ii) detergent active. Also disclosed is a cationized silicone delivery system comprising: a) 15-50 parts of a cationized fatty alkyl silicone copolymer; b) 5-50 parts of a cationized dimethiconol complex; and c) 1-50 parts of a cationized high viscosity lower alkyl silicone fluid with cationized silicone gum blend.
Abstract: In an apparatus and process for manufacturing a detergent bar, the bar comprises a first distinct zone comprising a first component and at least a second distinct zone comprising a second component. In an injection step, the first and second components are injected into the mold cavity via nozzle means having a first orifice through which the first component is injected. The second component is injected through a second orifice of the nozzle means. The first and second components solidify in the cavity to form the bar. The interface between the zones may be non-planar and/or such that the zones cannot be separated by a unidirectional cut. The first and second zones may respectively comprise detergent and a benefit agent. The first and second zones may differ in texture.
