Silicone oil-containing hair conditioner and preparation method thereof

Abstract

The invention provides a silicone oil-containing hair conditioner good in stability, comprising silicone oil, an emulsifier, a conditioning agent, a thickener, additives and deionized water. The emulsifier is a polymer having a molecular weight of 1000 to 5000 thousands and obtained by inverse emulsion polymerization of methacryloyloxyethyl trimethyl ammonium chloride and docosyl acrylate; the conditioning agent comprises polyquaternium and a small-molecular cationic surfactant; the thickener is a fatty alcohol; the additives include a preservative and a pH regulator; the components in percent weight in the conditioner are: the silicone oil 0.1-30.0%, the high-molecular emulsifier 0.5-4.0%, the polyquaternium 0.5-10%, the small-molecular cationic surfactant 0.1-8.0%, the fatty alcohol 0.5-10.0%, the preservative 0.1-0.3%, and the pH regulator 0.1-0.25%. The silicone oil-containing hair conditioner has a reasonable formula, a paste of the conditioner never thickens or bleeds during low-temperature storage, the conditioner can neutralize negative charge of shampoo remaining in hair, can smoothen the tangly hair and enable the hair to be easily combed, can impart gloss and smoothness to the air. The invention also provides a preparation method of the silicone oil-containing hair conditioner.

Description

technical field [0001] The invention relates to washing and care products for hair, in particular to a conditioner capable of conditioning, repairing and nourishing hair, and more particularly to a conditioner containing silicone oil with good stability. The present invention also relates to a preparation method of the above-mentioned silicone oil-containing conditioner. Background technique [0002] Hair is very important to a person's appearance, and having smooth, shiny hair is the pursuit of every beauty lover. At present, there are many hair care products on the market, including conditioners, ointments and hair masks. Conditioners are generally used in pairs with shampoo, which is provided with anionic and nonionic surfactants as the main raw materials. Decontamination and foaming effect, while the main raw material of conditioner is cationic surfactant, after shampoo wash hair, then use conditioner, it can neutralize the anionic surfactant and hair surface remaining ...

AI Technical Summary

Problems solved by technology

At present, hair conditioners containing silicone oil on the market generally use small molecule emulsifiers such as fatty alcohol polyoxyethylene ether (Pingpingjia), fatty acid monoglyceride, and self-emulsifying monoglyceride as emulsifiers. It is still relatively delicate and bright under the skin, but after freezing and returning to room temperature, the paste will become rough, and serious water separation and layering will appear. The reason for this phenomenon is that the small molecule emulsifier forms a layer in the system. The liquid crystal layer wraps the oil phase droplets. After a long period of freezing and returning to room temperature, the liquid crystal layer is destroyed, which causes a lot of problems for the storage of hair conditioner, especially in the cold north. To ensure that the product paste after winter is not rough, does not separate water, and does not delaminate is the subject of research by those skilled in the art.
