Abstract
There are provided: water-repellent cellulose beads that are excellent in water repellency, easily spreadable on the skin without leaving a white residue, and unlikely to cause squeaky impression, and exhibit a smooth tactile impression; and a method for producing the same. The water-repellent cellulose is obtained by surface-treating cellulose beads having, for example, a cumulative 50% particle size on a volume basis of 3 to 15 μm and a degree of sphericity of 0.6 to 1.0 with hydrogenated lecithin containing 40 to 85% by mass of phosphatidylcholine. The method for producing water-repellent cellulose beads includes: mixing cellulose beads, hydrogenated lecithin, and water to obtain a mixed liquid; and subjecting the mixed liquid to filtration.
