The invention provides personal wash compositions which deposit high levels of sunscreen while maintaining good lather. Enhanced deposition, from bar or liquid, is based on specific sunscreens used, particularly on their solubility.

Personal wash sunscreen compositions which deposit and lather well

The present invention relates to a multiphase cleansing bar having a plurality of phases of cleansing material. Adjacent phases preferably have different concentration levels of benefit components respectively and all the phases individually preferably have a substantially similar cleansing base consisting of a syndet base, a soap base, or mixtures thereof. These benefit components are emollients, moisturizers, nutrients, anti-aging materials etc. Segregation of the benefit rich component is expected to result in improved deposition of the benefit components on the skin during the product application, which improves the moisture barrier properties of the skin. Chemical and Theological compatibility between the phases is maximized and recycling of the product during production is facilitated with the use of a uniform cleansing base. Methods of producing the inventive bar by extruding and melt casting are also disclosed.

Personal washing bar having adjacent emollient rich and emollient poor phases

The present invention relates to bar compositions in which an emollient composition comprising thickened entrapped emollient is added to a base bar composition at or during time of extrusion to form macroscopic, concentrated domains of emollient droplets. Addition of entrapped droplets allows far greater deposition than if the non-trapped emollients had been mixed in directly to form chips which are then extruded to form final bar.

Personal washing bar compositions comprising emollient rich phase/stripe

A bar composition in which use of specific ratio of cationic to surfactant as been found to remarkably enhance deposition of oil/emollient benefit agent.
