Abstract
The invention belongs to the technical field of cosmetics, and particularly relates to amino acid facial cleanser and a preparation method thereof. The amino acid facial cleanser provided by the invention mainly comprises the following components in parts by weight: 7-20 parts of amino acid surfactant, 3-13 parts of auxiliary surfactant, 2-5 parts of thickening agent, 4-16 parts of humectant, 0.5-2 parts of pearling agent and 38.5-80.5 parts of water. The amino acid facial cleanser provided by the invention is close to the pH value of human skin, is safe and mild, and is skin-friendly and low in stimulation; the foam is rich and fine, and is high-efficiency and clean; moisten and nourish skin, and is fresh and tight.
Description
Technical Field
The invention belongs to the technical field of cosmetics, and particularly relates to amino acid facial cleanser and a preparation method thereof.
Background
The face cleansing cream on the market can be roughly divided into three types, namely a common surfactant type, a fatty acid salt type and an amino acid surfactant type according to the types of the surfactants.
The amino acid facial cleanser is a facial cleanser product which takes amino acid type surface activity as a main cleaning active ingredient, and the weakly acidic amino acid type surfactant is prepared from natural ingredients and is green and natural; the pH value is close to the human skin, and the pH value of the skin cannot be influenced; amino acid is a basic unit for forming protein, so that the product is mild and skin-friendly, has low irritation and proper cleaning capability, and is touted by consumers.
However, the amino acid facial cleanser is difficult to thicken, and the coating property and the foaming property of the facial cleanser are often influenced by adding the high molecular polymer for thickening, so that the amino acid facial cleanser is difficult to coat and melt in the using process, and the foaming time is long. The self-crystallizing thickening type amino acid facial cleanser has the problems of high stability such as alcohol precipitation, water yielding, layering and the like although the foaming is rapid and the foam is rich.
The two types of amino acid facial cleansers have respective defects, and the industrial application development of the amino acid facial cleansers is limited. This phenomenon is urgently to be solved.
Disclosure of Invention
The invention aims to provide an amino acid facial cleanser and a preparation method thereof. The amino acid facial cleanser provided by the invention has good stability; the pH value of the skin of a human body is within a proper range, so that the skin care liquid is safe and mild, is skin-friendly and has low stimulation; the foam is rich and fine, the cleaning is efficient, and the detergent is fresh and not tight after being washed.
The technical scheme of the invention is as follows:
an amino acid facial cleanser mainly comprises the following components in parts by weight: 7-20 parts of amino acid surfactant, 3-13 parts of auxiliary surfactant, 2-5 parts of thickening agent, 4-16 parts of humectant, 0.5-2 parts of pearling agent and 38.5-80.5 parts of water; the pH value of the amino acid facial cleanser is 5.5-7.5; the amino acid surfactant is potassium cocoyl glycinate, the auxiliary surfactant is cocamidopropyl hydroxysulfobetaine and decyl glucoside, the thickening agent is composed of acrylic acid (ester) copolymer and PEG-120 methyl glucose trioleate according to the weight ratio of 5:1, the humectant is glycerin, the pearling agent is ethylene glycol distearate, and the skin conditioner is yeast/rice fermentation product filtrate, dipotassium glycyrrhizinate, pseudo-ginseng, dendrobium officinale stem extract, polygonatum extract, poria cocos extract, radix scrophulariae extract and radix ophiopogonis extract.

As can be seen from the results of the trial skin feel evaluation of the volunteers in Table 5, the amino acid facial cleanser prepared in example 2 is superior in foaming property, cleansing effect and skin feel after use. The cleansing milk of comparative example 4 did not contain the appropriate co-surfactants cocamidopropyl hydroxysultaine and decyl glucoside, resulting in a significant reduction in lather, lather richness, and lather resiliency. The facial cleansers of comparative example 5 and comparative example 6 increase the ratio of acrylic acid (ester) copolymer, PEG-120 methyl glucose trioleate in the thickener, respectively, and the foaming performance, cleansing effect and skin feel in use are all in adverse directions.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can make appropriate modifications or improvements within the technical scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
