| 摘要 |
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. |
