Problems solved by technology

[0004] Emulsified silicone oil has been used in shampoo systems for more than ten years, but the emulsifiers used in the emulsified silicone oil currently on the market are all small molecule emulsifiers, such as isomeric tridecyl ether and lauryl ether sulfate Sodium salt, cetyl trimethyl ammonium chloride, octadecyl trimethyl ammonium chloride, lauryl polyoxyethylene ether, etc., these small molecule emulsifiers are firm to the emulsified coating of polydimethylsiloxane The emulsification effect is very good, and the emulsification effect is quite stable. However, these emulsified silicone oils are not easy to break during the shampooing process. They need to be diluted with a large amount of water to break the emulsion. If the dilution factor is not enough, most of the emulsified silicone oils have not had time to break the emulsion. and deposition, it is directly washed away by clean water, and only a small part of the silicone oil can be deposited on the hair surface to play a nursing effect. On the one hand, the effectiveness of the silicone oil cannot be fully utilized, and the cost of the shampoo is high. On the other hand, it also causes waste of emulsified silicone oil or clear water

Abstract

The invention provides cation silicone emulsion capable of rapidly breaking emulsion during the usage process to improve the silicone oil usage efficiency. The cation silicone emulsion includes by weight 25-70% of poly-dimethyl siloxane, 2-20% of poly- quaternary ammonium salt, 2-15% of macromolecule emulgator and remaining deionized water, and the cation silicone emulsion is formed by emulsification. The macromolecule emulgator is a macromolecule cationic opsonizing emulgator H305. The cation silicone emulsion can exist in a liquid shampoo system; achieve the effect of rapid breaking emulsion when the cation silicone emulsion is used. When the cation silicone emulsion is added into the liquid shampoo system to be used as an opsonizing component, the cation silicone emulsion can break the emulsion rapidly under the dilution of a little water, on one hand, the poly-dimethyl siloxane can be deposited on the surface of the hair to the uttermost so that the effects of smoothness in wet hair, brightness and no greasiness in dry hair can be achieved. On the other hand, the addition quantity of the silicone emulsion is reduced; the cost of the liquid shampoo is saved. The invention further provides the preparing method of the cation silicone emulsion and the application for the opsonizing component in the liquid shampoo system.

Description

technical field [0001] The present invention relates to a silicone oil, in particular to an emulsified silicone oil, and more particularly to a cationic emulsified silicone oil which can rapidly demulsify during use so as to improve the use efficiency of the silicone oil. The present invention also relates to the preparation method of the cationic emulsified silicone oil and its application in the shampoo system. Background technique [0002] Silicone oil is a common name for linear polysiloxane products. The commonly used silicone oil has all organic groups as methyl groups, so it is called methyl silicone oil or dimethylsiloxane or polydimethylsiloxane; according to methyl The degree of polymerization of silicone oil or the state at room temperature is different, and it can also be divided into low-viscosity silicone oil (general viscosity within 10,000 centistokes, which is also a low degree of polymerization), high-viscosity silicone oil (general viscosity of 10,000 cent...
