The present application relates to a hydrophobic polysaccharide microsphere, its preparation method and cosmetics, the method includes the following steps: providing a polysaccharide microsphere made of natural polysaccharide material; the hydrophobic modification step includes mixing a lauroyl lysine solution with the prepared polysaccharide microsphere. The polysaccharide microspheres are contacted so that lauroyl lysine is bound to at least part of the surface of the polysaccharide microspheres to obtain hydrophobic polysaccharide microspheres. After the polysaccharide microspheres are hydrophobically modified by using lauroyl lysine as a hydrophobic modification reagent, the polysaccharide microspheres have hydrophobicity, which can solve the hydrophilic problem of common cellulose, and can be applied to an oil-soluble system. The natural polysaccharide microspheres after hydrophobically modified by lauroyl lysine are not only endowed with good hydrophobicity, but also maintain their smooth skin feel, which has great potential in the field of cosmetics. |
