Abstract

See full text

Microparticles comprising carboxylated, sulfated, or phosphated cellulose nanocrystals (CNCs) and pigment nanoparticles are provided. In these particles, the cellulose nanocrystals and the pigment nanoparticles are agglomerated together thereby forming said microparticle, and wherein the pigment nanoparticles are bound to the surface of the cellulose nanocrystals. Cosmetic preparations comprising these microparticles are also provided. Finally, a method for producing the microparticles is provided. The method comprises the steps of a) producing an aqueous suspension of carboxylated, sulfated, or phosphated CNCs with pigment nanoparticles bound thereto; and b) drying said aqueous suspension to produce the microparticles.
