[Problem] To provide low-substituted hydroxypropyl cellulose having good binding properties, anti-capping performance and disintegration properties. [Solution means] When the content of the hydroxypropoxy group is 5 to 16% by mass, and all particles are classified into fine particles, spherical particles, long fiber particles, and short fiber particles by dynamic image analysis, the total particles To provide a low-substituted hydroxypropyl cellulose in which the volume fraction of the long fibrous particles is greater than 50.0%, and a solid preparation containing at least the low-substituted hydroxypropyl cellulose is provided. |
