Problems solved by technology

[0009] However, the thickening composition in Patent Document 1 has no description about thickening silicone oil, etc.
In addition, in Patent Document 2, although it is described that it has a thickening effect on the oily component of silicone oil, there is no description on the thickening effect on unsaturated free fatty acids, etc.
Furthermore, in Patent Document 3, although composite particles mixed with cosmetics are provided to prevent makeup from coming off, the composite particles themselves do not have a thickening effect on oily ingredients.
[0010] In addition, when long-term stability and storage stability are generally considered, it is also necessary to consider the separation properties of preparations such as cosmetics, but there is no description in these patent documents about the separation properties of the resulting thickening composition.

Embodiment 1～12

[0123] (Evaluation of dispersibility of surface hydrophobized CNF 1)

[0124] Each oil was prepared so that the base material (Hex-CNF DS: 0.73, Lau-CNF DS: 0.64) became 0.1% (w / w) concentration, each oil was stirred and subjected to ultrasonic treatment for 30 minutes, and the following Visual dispersibility evaluation was carried out according to the above evaluation criteria.

[0134] (Dispersibility evaluation of surface hydrophobized CNF 2)

[0135] For each oil, the base material (Hex-CNF BB-C DS: 0.73, Lau-CNF BB-C DS: 0.64) was prepared so that the concentration was 0.1% (w / w), and each oil was stirred for 30 minutes. Sonication was performed, and a visual dispersibility evaluation was performed using the above evaluation criteria. Except for using AEROSILR R972 (registered trademark, Nippon Aerosil Co., Ltd.) as the base material, it was treated in the same manner as a comparative example.

[0140] The results are shown in Table 2. It can be seen from Table 2 that for KF96L-1CS and KF96-10cs, Hex-CNF cannot be dispersed ...

Embodiment 19～27

[0143] (Evaluation of dispersibility of surface hydrophobized CNF 3)

[0144] For each oil, base materials with different degrees of Lau-CNF substitution and fibrillation were prepared so as to have a concentration of 0.1% (w / w), each oil was stirred and subjected to ultrasonic treatment for 30 minutes, and the above evaluation was used A visual dispersibility evaluation was performed based on the benchmark. In addition, the oil used is the same as that used in Table 2.

[0146]

[0147] The results are shown in Table 3. It can be seen from Table 3 that for KF96L-1CS, in Example 19 with a low degree of substitution, there is almost no sedimentation, and the dispersibility is high. On the other hand, Example 20 and Example 21 will settle after standing overnight. Compared with Example 20 and Example 21 with high substitution degree, Example 19 with low substitution degree has higher dispersibility.

Abstract

The issue of the invention is to provide an oily thickener which has a high thickening effect on oily components, such as silicone oil, nonpolar organic compounds, and low-polar organic compounds, andis easy to handle. As a solution, surface-hydrophobicized cellulose nanofibers for an oily thickener according to the present invention have an average thickness of 3-200 nm, and an average length of0.1 [mu]m or more, wherein an aqueous dispersion containing 1 wt% of the cellulose nanofibers has a viscosity value of 700-2100 mPa.s, hydroxy groups in cellobiose units thereof are substituted witha vinyl ester and / or an organic acid vinyl ester, and the degree of the substitution is 0.2-0.8.

Description

technical field [0001] The present invention relates to an oily thickener, which uses cellulose fibers to have a high thickening effect on oily thickeners, especially oily ingredients, and can form an oily thickener with a good feeling of use; an oily thickener; An oily thickener, an oily thickener capable of selectively adsorbing free fatty acids in sebum; and a cosmetic product in which the oily thickener is mixed. Background technique [0002] In the past, products in the form of paste, gel, emulsion or liquid were prepared by using a composition mixed with a polymer material and the like in a dispersion medium such as water, alcohol, or oil. As the polymer material, various synthetic polymers or natural polymer polysaccharides are used in order to impart thickening properties to products. [0003] In recent years, as the polymer material, cellulose nanofibers (hereinafter referred to as CNF) obtained by chemically treating cellulose that has been reduced to a nanometer ...
