Cellulosic particle

A cellulosic particle contains cellulose as its base constituent, and the percentage water absorption of the cellulosic particle measured by method B in ISO 15512:1999 is 11% or more and 20% or less.

A cellulosic particle contains 90 parts by mass or more and 99.5 parts by mass or less of cellulose; and 0.5 parts by mass or more and 10 parts by mass or less of a cellulose derivative.

A cellulosic particle includes: a cellulose-based core particle; a first coating layer covering the core particle and containing a polyamine compound; and a second coating layer covering the first coating layer and containing at least one selected from the group consisting of a wax, a linear-chain saturated fatty acid, a hydroxy fatty acid, and an amino acid compound.
