Description

A kind of scalp care compositions of the solid-state structure containing liquid crystal

Technical field

The present invention relates to daily use chemicals formula technique field, in particular to a kind of scalp care compositions.

Background technique

Most shampoos on the market have different degrees of head by test and itch phenomenon, wash even for antipruritic Shampoo also has such phenomenon, this belongs to the technical field of scalp care, and the nursing of scalp becomes this field now Mainstream technology content.In the prior art, P&G's Head&Shoulders shampoo includes that its mating useful zpt of patent carries out conditioning function to scalp Can, the patented technology that the glycerol of Uniliver's also useful high-content is improved as scalp discloses, so, the technology one that scalp improves Directly paid attention in the industry, and is continued to introduce new.

In two-in-one dandruff control shampoo containing technology at this stage, polysiloxane particle and anti-dandruff particle are especially carried with flocculation Conditioning and anti-dandruff effect are brought to deposit to hair or scalp, is had in a short time obviously two-in-one and anti-dandruff Effect, however, for the silicone oil particle added and the effective particle of solid such as zpt etc. of suspending, need to be added such as pearly-lustre, The suspending agents such as card wave suspend.This technological means itself has no great technological deficiency, but the type of product can be relatively more limited, And not yet illustrate the technical solution of control deposition definitely, and the health of deposition and scalp is closely bound up, it is excessively high Have biggish scalp burden, the actual efficacy of relatively few skin conditioning then without a head.

Similar, it is also known in the field for providing the dandruff control shampoo of conditioning effect.Such as Chinese Patent Application No. 00809131.5 and Chinese Patent Application No. 00808517.X discloses a kind of by anionic surfactant and cationic Guar The flocculate that gum derivative is formed carries silicone oil particle and zpt particle, by for cationic guar derivative parameter The ability for carrying effective particulate matter is preferably realized；Chinese Patent Application No. 201480045888.9 also disclose it is a kind of by yin from Sub- surfactant, amphoteric surfactant and cationic guar derivative carry selenium disulfide, zinc pyrithione and silicon Oxygen alkane realizes the effect of anti-dandruff conditioning, the former uses pearlescent flake and is used as suspending agent, and the latter is using macromolecules such as card waves As suspension stabilizer.

Both suspension systems are the suspension system widely used at present, but both suspension systems respectively have its limitation Property, such as pearly-lustre class suspending agent, it will appearance is generated and is directly changed, and changes its wet hair and drying hair effect, and card wave class Raw material will change the wadding glue state of product, larger change can also be generated to the conditioning effect of product, therefore find other Approach realizes the stable suspersion of product, will be carried out other effect, provides other selection.

Summary of the invention

The purpose of the present invention is to provide another to be different from another liquid crystal suspension that pearly-lustre suspends, card wave suspends Scheme, this liquid crystal suspension scheme can there are this to have longer netted linear liquid crystal in shampoo, while using this liquid crystal skill Art provides a kind of novel scalp care shampoo technical solution in conjunction with the scalp care result of study of our company.The composition is logical Cross composition framework rationally build, the limitation of the synergy between raw material, raw material key parameter, be made that liquid in the product Crystalline state, the effective particulate matter for the product that can suspend, and scalp care scheme are different from existing disclosed technology contents.Group It is mild to close object composition, various people are applicable in, there is significant scalp care effect, low in cost, application is simple and direct.

Technical scheme is as follows:

A kind of scalp care compositions of the solid-state structure containing liquid crystal, the raw material containing following weight percent proportion:

(A) anionic surfactant 5-20%；

(B) fatty acyl both sexes base diacetin 0.1-10%；

(C) hydroxystearin 0.3-10%；

(D) nonionic surfactant 0.05-5%；
