  • Two-phase cosmetic composition
    Patent number: 6019991
    Abstract: A two-phase cosmetic composition is provided packaged in a clear container. Within the container is an oil and an aqueous phase separated from one another but when shaken form a highly temporary, clear emulsion. One of the phases is colored with a dye while the other is ordinarily water white. Color stability may be enhanced through use of a UV protectant. A bead control agent may be included to eliminate unsightly bead formation on walls of the container. Sorbitan derivatives are useful for this purpose.
