[Problem] To provide an oil thickener which has high viscosity increasing effect on an oily ingredient such as silicone oil, a non-polar organic compound, a low-polarity organic compound or the like and which has good handlability

[Means to Solve the Problem] Surface-hydrophobized cellulose nanofibers for an oil thickener which are cellulose nanofibers having an average thickness of 3 to 200 nm and an average length of 0.1 μm or larger, and a 1 wt. % aqueous dispersion of which has a viscosity of 700 to 2100 mPa.Math.s, and hydroxyl groups in cellobiose units of which are substituted by vinyl esters and/or organic acid vinyl esters in a substitution degree of 0.2 to 0.8.

A process for producing dried, vinyl carboxylate surface-modified microfibrillated cellulose having improved mechanical properties and a microfibril structure and a process for producing a vinyl carboxylate, surface-modified microfibrillated cellulose—thermoplastic polyester or thermoplastic polyolefin composite material having improved mechanical strength properties utilizing dried, vinyl carboxylate surface-modified microfibrillated cellulose.

Disclosed are a sorbent produced by recycling waste paper, which is an eco-friendly recycling paper resource, to adsorb and remove a marine spilled oil and other types of oil and a method of producing the same. The oil sorbent is produced by hydrophobizing a biomass material such as waste paper using a gas-grafting method. Compared to the oil sorbent of the prior art formed of synthetic resin, it is possible to provide excellent oil adsorption selectivity, a high oil adsorption rate, and a low water absorption rate. Therefore, an incineration process for processing the waste oil sorbent after use is easy advantageously. The oil sorbent generates less harmful substances during combustion because the eco-friendly material is used. Since a biomass material is hydrophobized using vegetable fatty acids, decomposition is performed fast within a short time in a landfill process, and there is no risk of environmental pollution.
