Abstract
Official abstract text for this publication.
A cellulose particle includes a mother particle containing cellulose as a main component, a first coating layer containing at least one polysaccharide selected from the group consisting of a basic polysaccharide and a salt of the basic polysaccharide, the first coating layer being provided on a surface of the mother particle, and a second coating layer containing at least one hydrophobic compound selected from a fatty acid, a fatty acid metal salt, an acylated amino acid, or an acylated amino acid salt, the second coating layer being provided on the first coating layer.
First claim
Opening claim text (preview).
What is claimed is: 1 . A cellulose particle comprising: a mother particle containing cellulose as a main component; a first coating layer containing at least one polysaccharide selected from the group consisting of a basic polysaccharide and a salt of the basic polysaccharide, the first coating layer being provided on a surface of the mother particle; and a second coating layer containing at least one hydrophobic compound selected from a fatty acid, a fatty acid metal salt, an acylated amino acid, or an acylated amino acid salt, the second coating layer being provided on the first coating layer. 2 . The cellulose particle according to claim 1 , wherein the polysaccharide is chitosan. 3 . The cellulose particle according to claim 1 , wherein the hydrophobic compound is at least one selected from a fatty acid metal salt or an acylated amino acid salt. 4 . The cellulose particle according to claim 3 , wherein the hydrophobic compound is a fatty acid metal salt. 5 . The cellulose particle according to claim 3 , wherein the fatty acid metal salt is calcium stearate. 6 . The cellulose particle according to claim 4 , wherein the fatty acid metal salt is calcium stearate. 7 . The cellulose particle according to claim 3 , wherein the acylated amino acid salt is at least one selected from aluminum stearoyl glutamate or aluminum myristoyl glutamate. 8 . The cellulose particle according to claim 1 , wherein the polysaccharide is chitosan, and the hydrophobic compound is calcium stearate. 9 . The cellulose particle according to claim 1 , wherein a coating amount of the first coating layer with respect to the mother particle is 0.2% by mass or more and 10% by mass or less. 10 . The cellulose particle according to claim 9 , wherein the coating amount of the first coating layer with respect to the mother particle is 0.25% by mass or more and 3% by mass or less. 11 . The cellulose particle according to claim 1 , wherein a coating amount of the second coating layer with respect to the mother particle is 0.5% by mass or more and 25% by mass or less. 12 . The cellulose particle according to claim 11 , wherein the coating amount of the second coating layer with respect to the mother particle is 3% by mass or more and 12% by mass or less. 13 . The cellulose particle according to claim 1 , wherein a ratio of a coating amount of the first coating layer to a coating amount of the second coating layer is 0.04 or more and 2 or less. 14 . The cellulose particle according to claim 1 , wherein a volume average particle diameter of the cellulose particles is 3 μm or more and 10 μm or less.
