Abstract

Official abstract text for this publication.

An object of the present invention is to provide a microspherical particle having an excellent massage effect. Another object of the present invention is to provide a microspherical particle that provides an excellent massage effect and cleaning effect when formulated in a cleaning composition and the like. A microspherical particle is formed of powdered cellulose so that the microspherical particle has an average particle diameter of 50 to 2,000 μm, a sphericity of 0.7 to 1.0, and a dry hardness of 1 to 5,000. A soft type thereof has a dry hardness of 1 to less than 210, and a hard type thereof has a dry hardness of 210 to 5,000. Such microspherical particle is formulated to make a massage composition or a cleaning composition.

First claim

Opening claim text (preview).

A microspherical particle comprising powdered cellulose, the microspherical particle having an average particle diameter of 50 to 2,000 μm, a sphericity of 0.7 to 1.0, and a dry hardness of 1 to 5,000. 2 . The microspherical particle according to claim 1 , wherein the microspherical particle is a granulated product without a binder for binding the powdered cellulose to each other. 3 . The microspherical particle according to claim 1 , wherein the microspherical particle consists substantially of the powdered cellulose. 4 . The microspherical particle according to claim 1 , wherein the dry hardness is 210 to 5,000. 5 . The microspherical particle according to claim 4 , wherein the powdered cellulose has an average particle diameter of 10 to 50 μm and an average polymerization degree of 50 to 750. 6 . The microspherical particle according to claim 1 , wherein the dry hardness is 1 to less than 210. 7 . The microspherical particle according to claim 6 , wherein the powdered cellulose has an average particle diameter of 10 to 50 μm and an average polymerization degree of 50 to 2,000. 8 . A composition comprising: the microspherical particle according to claim 1 ; and a base applicable to skin, wherein the composition is used for massage on skin. 9 . A composition comprising: the microspherical particle according to claim 1 ; and a surface active substance, wherein the composition is used for cleaning. 10 . The microspherical particle according to claim 5 , wherein the microspherical particle is a granulated product without a binder for binding the powdered cellulose to each other. 11 . The microspherical particle according to claim 5 , wherein the microspherical particle consists substantially of the powdered cellulose. 12 . The microspherical particle according to claim 7 , wherein the microspherical particle is a granulated product without a binder for binding the powdered cellulose to each other. 13 . The microspherical particle according to claim 7 , wherein the microspherical particle consists substantially of the powdered cellulose. 14 . The microspherical particle according to claim 8 , wherein the microspherical particle is a granulated product without a binder for binding the powdered cellulose to each other. 15 . The microspherical particle according to claim 8 , wherein the microspherical particle consists substantially of the powdered cellulose. 16 . The microspherical particle according to claim 9 , wherein the microspherical particle is a granulated product without a binder for binding the powdered cellulose to each other. 17 .
