Embodiment 1

[0100] Preparation of octenyl succinate corn starch aluminum myristate

[0101] Add 100 g of cornstarch (cornstarch Y manufactured by Sanwa Starch Co., Ltd.) (converted to anhydrous value) (converted to 0.62 moles in terms of anhydrous monosaccharide units) into 200 g of water, and stir with a stirrer (スリーワンmotor) and a propeller. It is uniformly dispersed, while adding an appropriate amount of 1N aqueous sodium hydroxide solution to maintain pH 7.9-8.2, and 5.0 g of octenyl succinic anhydride (Rikasid OSA manufactured by Nippon Chemical Co., Ltd.) (0.04 times the mole relative to starch) A small amount of addition was continued over 1 hour to make it react. The reaction was carried out at 35°C for 5 hours (dropwise addition was started until the reaction was complete). A part of the reactant was taken out, washed with a small amount of water and dried, and the degree of substitution (DS) was measured. As a result of the degree of substitution (DS) measurement, the degree of...

Embodiment 2

[0103] Preparation of octenyl succinate mung bean starch aluminum lauroyl glutamate

[0104] Except that the cornstarch in Example 1 is replaced by mung bean starch, and potassium myristate is replaced by sodium lauroyl glutamate 2.32g (2.3% by mass relative to the starch), the same operation is carried out to obtain 92.3g Mung bean starch octenyl succinate aluminum lauroyl glutamate.

Embodiment 3

[0106] Preparation of hemp cellulose zinc palmitate octenyl succinate

[0107] In addition to replacing the cornstarch in Example 1 with hemp cellulose powder, the reaction with octenyl succinic anhydride was carried out at 50° C. for 5 hours, and potassium myristate was replaced with 4.00 g of sodium palmitate (relative to cellulose: 4.0 mass %), and replace aluminum chloride with zinc chloride 4.0g (relative to sodium palmitate is 2.04 times mole), carry out the same operation, obtain 90.4g of octenyl succinic acid hemp cellulose palmitic acid zinc.

Abstract

The present invention provides a surface-treatment starch or surface-treatment cellulose with excellent properties preferred by cosmetics, such as moist, extensiveness and the like. According to the surface-treatment starch or surface-treatment cellulose provided by the invention, the surface of starch or cellulose particles is represented by the following formula (1) or (2).

Description

technical field [0001] The present invention relates to surface-treated starch or surface-treated cellulose, cosmetics and a method for producing surface-treated starch or surface-treated cellulose. Background technique [0002] So far, powders used in cosmetics have been surface-treated in many cases to improve their properties (dispersibility, optical resistance, surface activity suppression, water repellency (water repellency), oil repellency, adhesion to skin, etc.) . Surface treatment includes treatment by physical adsorption and treatment by chemical reaction with surface functional groups. As the treatment by physical adsorption, there is a method of dissolving the substance to be treated in a solvent, mixing the powder, and distilling off the solvent; or dissolving the substance to be treated in ethanol, mixing the powder, Adding water reduces the solubility of the substance to be treated, precipitates and adsorbs on the powder. As an example of a chemical reactio...
