Shiseido patents oil-cleansing composition.
* U.S. 7,879,779 B2; Shiseido Co., Ltd., has patented an oil-based
cleansing composition. It is comprised of a nonionic surfactant having a
HLB of 8 to 10 and an oil component. The IOB of the oil component is
0.02 to 0.07, and the mass ratio of first component (A) and second
component (B) is 1:4 to 2:1. The oil-based cleansing composition
satisfies the following conditions: the amount of water in the
composition is less than 5% by mass, and a micellar aqueous solution
phase or a bicontinuous microemulsion phase is formed when said
oil-based cleansing composition and water arc mixed in the ratio of 4:6.
The micellar aqueous solution phase is optically isotropic exhibiting a
clear to slightly blue, translucent appearance, and the bicontinuous
microemulsion phase is optically isotropic exhibiting a transparent
