Title: NETWORKED DISPERSION OF BIOCELLULOSE MICROFIBRILS IN WATER
Abstract:
The present invention relates to a networked dispersion of biocellulose microfibrils in water wherein the biocellulose microfibrils have carboxylic groups substituted for alcohol groups, are 30-60 nm in number average diameter with a maximum diameter of 60-100 nm, and are dispersed in an aqueous phase while forming a network. The networked dispersion of biocellulose microfibrils in water according to the present invention exhibits excellent skin compatibility and has the effect of allowing the skin to increase in water absorption, elasticity, and smoothness. In addition, not only does the networked dispersion of biocellulose microfibrils in water form micro-networks on the skin to prevent microdust from being brought into direct contact with the skin, but also negative charges of the networked dispersion repel those microdust to reduce microdust attachment, so that the present invention can be widely utilized in developing a variety of compositions for effectively blocking microdust. Further, the dispersion of the present invention has the effect of forming a strong network on a keratin structure such as hairs and hand and foot nails to protect the ketatin structure and of exerting no damages on the surficial cuticle layer of the keratin structure even during the removal thereof.
