Abstract

The invention relates to plant-derived cellulose-containing particles useful as rheology modifiers and to a process for preparing cellulose-containing particles from plant material, which process involves treating said plant material with a peroxide reagent. The process can be controlled to produce cellulose-containing particle having a viscosity up to about 7500 or 8000 cps.

Claims

1. A cosmetic composition comprising a binder, and less than 10 wt % plant-derived cellulose particulate material, wherein the plant-derived cellulose particulate material comprises less than 30 wt % extractable glucose;

and extractable xylose in an amount of at least 5% of the amount of extractable xylose in the starting plant material.
