    摘要： The present invention provides resin beads that can provide various types of products, such as a cosmetic having excellent tactile impression, spreadability on the skin, and transparency, that can be substituted for resin particles composed of a synthetic material derived from petroleum, and that have favorable biodegradability, and the present invention also provides various types of products, such as a cosmetic using the resin beads. The resin beads are formed with a resin containing cellulose as a main component. The resin beads have a cumulative 50% particle size on a volume basis of 50 μm or smaller, a degree of sphericity of 0.7 to 1.0, a degree of surface smoothness of 70 to 100%, a degree of solidity of 50 to 100%, and a biodegradation rate for 5 days, as measured in accordance with JIS K6950:2000 (ISO 14851:1999), of 20% or more, and the content of the cellulose in the resin is 90 to 100% by mass. In addition, the present invention provides a product of any one of a cosmetic, a dermatological preparation, a paint, a shaped article, a film, a coating agent, and a resin composition which contain the resin beads.

    摘要： A fine cellulose fiber in which when the fine cellulose fiber is formed into a dispersion, the dispersion has very high light transmittance and viscosity, and a method for producing the fine cellulose fiber. The fine cellulose fiber has a fiber width of 1 to 200 nm. A part of hydroxy groups of the cellulose fiber are substituted with a predetermine functional group to introduce an ester of phosphorus-oxo acid, and the introduction amount of the functional group is more than 2.0 mmol per 1 g of the cellulose fiber. For producing the fine cellulose fiber, to cellulose fiber is added a solution having a pH of less than 3.0 and including an additive (A) containing at least one of a phosphorus-oxo acid and a phosphorus-oxo acid metal salt and an additive (B) containing at least one of urea and a urea derivative, and the mixture is heated to perform fibrillation.

    摘要： A method and composition is provided for positioning a polymeric material having particulate matter disposed therein in a subterranean formation penetrated by a wellbore. The composition consists essentially of a hydrocarbon oil, a quaternary salt of an essentially undegraded, cellulose sulfate, solid particulate matter in an amount equal to from about 0.25 to about 22 pounds of particulate matter per gallon of hydrocarbon oil and an acid-settable thermosetting resin in an amount equal to from about 0.1 to about 5.0 gallons per cubic foot of particulate material. The composition is placed in contact with a subterranean formation in a wellbore by a method comprising injecting a first mixture consisting essentially of said quaternary salt of an essentially undegraded cellulose sulfate mixed with hydrocarbon oil followed by the injection of the composition with a post injection of an additional quantity of the quaternary salt in oil.
