Abstract

The invention discloses the preparation and application of a cellulose nano-whisker stabilized Pickering emulsion for hair care. The method comprises the following steps: adding a cationic surfactant to the CNC suspension, adding water, and performing ultrasonic treatment under temperature control conditions to obtain a cationic modified CNC suspension; mixing the cationic modified CNC suspension with an organic The silicone oil is mixed and emulsified to obtain a Pickering emulsion stabilized by cellulose nano-whiskers. The present invention uses cationic surfactants to modify cellulose nano whiskers, improves its ability to emulsify silicone oil, prepares stable Pickering emulsions and applies them to hair care products, and can reduce the impact on the environment and human body caused by the use of traditional surfactants. harm, and has greater economic benefits in the development of green daily chemical products.

Description

technical field [0001] The invention belongs to the field of hair care, and in particular relates to a preparation method and application of a cellulose nano-whisker stabilized Pickering emulsion for hair care. Background technique [0002] Hair care products have become the necessities of modern people's life. Under normal circumstances, the surface of the hair has a negative charge, making the hair difficult to comb. Therefore, it is necessary to add cationic surfactants in hair care products. After using hair care products, the cationic surfactant is adsorbed on the hair surface, neutralizes the negative charge on the hair surface, and improves the combability of the hair. Due to the insoluble property of silicone oil in water, silicone oil can form a thin film on the hair surface during rinsing, which improves the combability of hair, and increases the gloss and softness of hair. The shampoo and conditioner lotion products on the market mainly rely on the combination ...
