Background

The eyes are human visual organs, have complicated structures similar to skin but completely different structures, and are easily damaged under the action of external stimulation, many cosmetics contact the eyes to different degrees in the use process, so that the risk of damage to the eyes is greatly enhanced, and the eye damage of the cosmetics becomes serious harmful events in life, wherein in Zhaokang , the acute eye stimulation damage characteristics of different types of cosmetics are mentioned, various types of cosmetics such as hair cosmetics, eye creams, masks, skin cleaning cosmetics, color cosmetics and the like have different eye stimulation damages, wherein the incidence rate of eye stimulation of the hair cosmetics and the skin cleaning cosmetics is higher, the degree is also higher, and reversible inflammatory changes or irreversible tissue damage can be generated in the long-term stimulation.

Detailed Description

The cleansing cosmetic composition, the method for preparing the same, and the cosmetic of the present invention will be described in further detail in with reference to specific examples.

The embodiment of the invention provides cleaning cosmetic compositions, which are prepared from the following raw materials in percentage by weight:

the N-fatty acyl hydrolyzed protein salt is coconut acyl hydrolyzed oat protein salt, and the polymerization degree of a hydrolyzed oat protein or oat amino acid structural unit in the structure is 300-1000.

The principle and advantages of the above cleaning cosmetic composition are as follows:

the results obtained from relevant in vitro experiments show that the irritation score is directly dependent on the active substance concentration of the tested surfactant, or in other words, dose dependent, whereas in actual use, the surfactant micelles of the composition, structure no are less binding to the surfactant monomer molecules, and the surfactant monomer molecules more readily acquire the available free energy to break loose and bind to proteins on the conjunctiva, cornea or iris.

Based on abundant experience and a great deal of research, the inventor of the invention discovers that a relatively large composite stable micelle can be formed by compounding the cocoyl hydrolyzed oat protein salt with the cocoyl glycinate and the cocoate and reasonably controlling the polymerization degree of a hydrolyzed oat protein or oat amino acid structural unit in the cocoyl hydrolyzed oat protein salt structure to be 300-1000, so that the molecular weight of free surfactant monomers is greatly reduced, and the acute eye irritation of the face cleaning cosmetic is finally reduced, and the principle can be summarized into the following two aspects:

, the formation of micelles reduces the available free energy of surface interaction, the difficulty of obtaining the energy required for surfactant molecules to break out of the micelles and bind to the protein surface is greatly increased, and the curvature of the micelles makes the surface area of the micelles actually available for binding to the conjunctiva, cornea or iris surface smaller due to the constraints of surface tension and curvature radius;

in another aspect, the induction of irritation is thought to be a dynamic process of conjunctival or corneal binding of surfactant monomers followed by transport of these monomers to the excitable living tissue, thus the free molecular weight of the surfactant monomer available for this process is critical.

Meanwhile, the N-fatty acyl hydrolyzed protein salt, the cocoyl glycinate and the coconut oleate are compounded to mutually make up the defects of loose foam and poor stability of the independent components, so that the composition has fine, rich and stable foam, and the washed skin is fresh and natural and has a refreshing feeling.

Specifically, the structure of the cocoyl hydrolyzed oat protein salt may be represented as follows:

wherein the content of the first and second substances,

namely hydrolyzed oat protein or oat amino acid structural units, and the polymerization degree n is 300-1000.

Preferably, the cleaning cosmetic composition is prepared from the following raw materials in percentage by weight:

more preferably, the cleaning cosmetic composition is prepared from the following raw materials in percentage by weight:

in specific examples, the "salt" of the N-fatty acyl hydrolyzed protein salt, cocoyl glycinate, coconut oleate may each independently be a sodium or potassium salt.

The preparation method of the cleaning cosmetic composition comprises the following steps:

mixing the raw materials, heating to 80-90 ℃, purifying, refining and cooling.

In specific examples, the mixture is heated to 80-90 ℃ and then stirred for 25-35 min to mix uniformly.

In specific examples, the purification and refinement method comprises mixing, standing, and filtering with 200 mesh filter cloth.

The embodiment of the invention also provides application of the cleaning cosmetic composition in preparing cleaning cosmetics, in particular cosmetics, and components of the cosmetics comprise the cleaning cosmetic composition.

In specific examples, the cosmetic is prepared from the following raw materials in percentage by weight:

in specific examples, the cosmetic is prepared from the following raw materials in percentage by weight:

in specific examples thereof, the fatty acid is palmitic acid and/or stearic acid.

Preferably, the fatty acids are palmitic acid and stearic acid, and after a small amount of palmitic acid and stearic acid is fully dispersed in the system by the polyhydric alcohol, the palmitic acid and stearic acid have strong interaction (hydrophobic interaction between hydrocarbon chains and hydrogen bond combination between polar heads) with the N-fatty acyl hydrolyzed protein salt and the cocoyl glycinate salt, so that the fatty acids and composition molecules are closely arranged on the surface in an oriented mode, the micelle property of the composition is changed, the thickening effect is further achieved by step , the stability of the formula viscosity is enhanced, and meanwhile, the irritation of the palmitic acid and the stearic acid to eyes is small.

In specific examples thereof, the polyol is glycerol.

In specific examples, the thickener is a modified corn starch and/or acrylate copolymer emulsion.

Preferably, the thickener is a modified corn starch and acrylate copolymer emulsion. The modified corn starch is hydroxypropyl starch phosphate and is synergistically thickened with the acrylate copolymer emulsion, so that the overall thickening efficiency of the formula can be improved, the stability of viscosity is enhanced, and the formula has better shear resistance.
