As will be recognized by those of skill in the pertinent art, the described embodiments may be modified in various different ways without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.

The purpose of this application is overcome the not enough of prior art at hair care function, use non-silicone oil, high content grease and surfactant, it is suitable to realize normal atmospheric temperature viscosity, stability is outstanding, have good foaming and cleaning ability, and have excellent liquid crystal gel composition of hair care effect, the problem that has good product stability and good foaming ability under the high grease that contains is mainly solved to the composition of this application, the problem of keeping its outstanding hair care and soft hair's effect under the high surfactant that contains has been solved simultaneously, also accomplish the controllability of high solid content composition viscosity for its simple manufacturing process and repeatability are strong, the composition of preparation has sufficient shelf life stability effect, be fit for depositing simultaneously, filling and use are convenient, be fit for industrial production.

Unlike the simple emulsifying or compatibilizing system of the conventional art, the applicant found through experiments that when a suitable oil (fatty acid glyceride) and a suitable surfactant are selected and constructed through a specific parameter ratio, an amphiphilic colloidal gel structure cream composition can be obtained, which shows excellent foaming performance and simultaneously has excellent hair care and softening effects, but at present, although the phenomenon cannot be well explained, the liquid crystal structure is a special hydrophilic or lipophilic structure, so that the dispersing foaming of the surfactant in water is not affected, the adhesion and deposition of the oil-based compound on the hair are not affected, and thus the unexpected effect is obtained.

component C: polyols having IOB values (inorganic-organic balance) below 3.5;

component D: bezoar acid and/or taurine salts;

component E: a pH value adjusting buffer pair combination;

and (3) a component F: pure water.

Through the mixing of above-mentioned raw materials, can form the liquid crystal structure that has "maltese" cross, product outward appearance breaks through traditional emulsion and is white outward appearance simultaneously, presents a semi-permeable gel, has fine and pushes away the experience sense, stores, fills and use simply. Unlike the traditional simple use of basic mixture of surfactant, grease and wax, the hair care composition of the application firstly has good stability, and can not generate layering and demulsification phenomenon after being stored at 48 ℃ for 6 months, but the traditional mixture of surfactant and grease can not be stabilized, and the demulsification and layering phenomenon of the solution can be generated.

In one embodiment, the hair care composition of the present application comprises, in weight percent:

polyols having IOB values below 3.5, totaling 0.5-2%;

bezoar acid and/or taurine salts accounting for 0.14-0.54%;

and the balance of pure water.

In one embodiment, the mass ratio of the fatty acid glyceride in the vegetable oil and/or the wax containing the fatty acid glyceride is more than or equal to 60%. In a compound molecule, covalent bonds formed by different kinds of atoms have different electron-attracting abilities, and thus, a common electron pair is necessarily biased toward an atom having a higher electron-attracting ability, and thus, an atom having a lower electron-attracting ability exhibits positive polarity. Such covalent bonds are called polar covalent bonds, abbreviated as polar bonds. The fatty glyceride has medium polarity and even very high polarity, the mass ratio of the fatty glyceride is more than or equal to 60 percent, the fatty glyceride is more easily influenced by a polar emulsifier, and certain solubilization and emulsification coordination effects are generated, so that the prepared composition has stronger stability.

In one embodiment, in component A, the fatty acid glyceride compound, or the vegetable fat or wax containing a fatty acid glyceride, has a carbon number of 30 or more, preferably between 30 and 60. The melting point of the compound can be far higher than the room temperature by more than 30 ℃ only when the carbon number is more than 30, the compound has good crystallinity, and can be easily worth liquid crystal products. Meanwhile, if the number of carbon atoms is too high and exceeds 60, the crystallinity of the product is too strong, and the formed crystals are easy to generate irregular phenomenon, so that the generation of the cross liquid crystals of Maranta is not facilitated.

In one embodiment, the mass ratio of component a to component B is 50% to 80%. The applicant finds through experiments that when the mass ratio of the component A to the component B is 50% -80% by combining the following components of the anionic surfactant, the semi-permeable liquid viscous gel can be formed, and the liquid crystal structure of the cross of the Maranta appears when the semi-permeable liquid viscous gel is observed under a polarized light microscope, and meanwhile, the liquid crystal structure has good softening and hair care effects. When the component A is too low, the component A/component B is less than 50%, good hair care and softening effects cannot be achieved, and meaning is lost. When the ratio of the component A to the component B is out of the range of 50-80%, solid white thin emulsion is formed, and no liquid crystal structure exists under polarized light.

In one embodiment, the mass ratio of component B to component D is 45% -55%.

The applicant found through experiments that component D is a key ingredient of the hair care composition of the present application, and component B/component D strictly follows the proportion of 45% -55%, if component D is lost, the cleaning power of the hair care composition will be greatly improved, and the effects of hair care and softening are lost. The general knowledge in this field does not temporarily explain the occurrence of this phenomenon, and according to a further theoretical knowledge of the surfactant, the applicant believes that acids or salts, possibly of the same anionic structure, have a composition which reduces the presence of the surfactant in the form of a salt and increases the presence in the form of an acid, in order to obtain a lower cleaning power and a better hair care effect.

waxes containing fatty acid glycerides include lacquer fruit waxes. It should be understood that the above components are only listed as common raw materials, and not only the above components can be used, but other raw materials capable of achieving similar functions, if used instead of the above components, constitute direct replacement of the fatty acid glyceride compounds or the vegetable oil or wax containing the fatty acid glyceride in the present application.

The applicant finds through experiments that the anionic surfactant containing the sulfonic acid group can well wet the component A, properly decompose and aggregate the component A to form semi-permeable liquid viscous gel, and the semi-permeable liquid viscous gel has a liquid crystal structure of a cross of Maranta when observed under a polarized light microscope and has good softening and hair care effects. Meanwhile, the sulfonate surfactant is replaced, or the ratio of the component A/component B is out of 50% -80%, so that a solid white thin emulsion is formed, no liquid crystal structure exists under polarized light, the phenomenon cannot be explained temporarily by common knowledge in the field at present, and the applicant considers that the hydrophilic group contains the anionic surfactant with the specific structure of the sulfonic acid and has specific affinity compatibility with the fatty glyceride compound, and the gel structure can be formed by dispersion and swelling in the aqueous solution.

The application reasonably regulates and controls the anionic surfactant and the acid and salt (component D) corresponding to the surface active hydrophilic group structure, and constructs the optimal ratio of the anionic surfactant containing the sulfonic acid group in the presence of the acid and the salt, so that the composition breaks through the specific composition in the related field at present, has good fatting effect, cleans hair, and simultaneously has excellent hair care and softening effects.
