Description

Mild amino acid facial cleanser and preparation method thereof Technical Field The invention belongs to the technical field of daily cosmetics, and particularly relates to a mild amino acid facial cleanser and a preparation method thereof. Background The facial cleanser is one of basic products for skin cleaning and nursing, and is widely applied to daily facial cleaning, cleansing residue and sun protection residue removal, and cleaning of grease, sweat and environmental particulate matters. With the increase of people with sensitive muscles and barrier damaged muscles, the market demand for mild amino acid facial cleanser with low stimulation, low tightness, enough cleaning power and fine foam is remarkably improved. The existing amino acid cleansing system mostly adopts the combination of glutamate, sarcosinate, betaine isothermal and surface activity, but in practical application, the contradiction still occurs frequently that the increase of the surface activity content for improving the cleaning force and the foam quantity can lead to the increase of the tightening and stabbing pain probability after flushing, and the decrease of the surface activity content is milder, but the experience problems of insufficient degreasing, heavy residue and thin foam are easy to occur. In addition, many amino acid systems have significant foam decay under hard water (Ca 2+/Mg2+ containing) conditions, or viscosity drift, delamination, low temperature haze after salt/polyol, thickener addition, resulting in narrow formulation window, poor stability. Along with the improvement of the requirements of consumers on 'sensitive muscle availability and long-term use without hurting a barrier', and the severe requirements of electronic commerce channels on transportation, temperature difference and shelf life stability, a need exists for a mild amino acid cleansing milk which can still have enough cleaning power, fine foam and good flushing feel under the condition of low surface activity, and simultaneously maintain stable viscosity and appearance under the condition of hard water and temperature difference. If the contradiction can not be solved, inconsistent product experience, increased complaint rate and batch stability risk are caused. Disclosure of Invention The invention aims to solve the problem that the conventional amino acid facial cleanser is difficult to take into account between mildness, cleaning power, foam fineness, hard water adaptation and viscosity stability, and particularly has the advantages of (1) insufficient cleaning power under the requirements of low stimulation and low tightness, (2) foam attenuation and decontamination reduction under the hard water condition, and (3) poor thickening stability (salt sensitivity, viscosity drift under the temperature difference and low Wen Hunzhuo/layering). Therefore, the invention provides a mild amino acid facial cleanser and a preparation method thereof. The aim of the invention can be achieved by the following technical scheme: the invention provides a mild amino acid facial cleanser, which is characterized by constructing a difunctional mild cleaning synergistic system, a micro complex foam stabilizing system and a reversible network thickening system, and specifically comprises the following components: (1) Dual function mild cleansing synergy system: Amino acid anionic surfactant is used as main material, amphoteric surfactant and small amount of nonionic surfactant are combined, and 'polar-nonpolar cleaning assistant' is introduced, so that the formula can maintain the removal capability of sebum/sun-proof film under the condition of lower active matter content, and simultaneously, the irritation and tightness are reduced. Disodium cocoyl glutamate (Disodium Cocoyl Glutamate) or sodium lauroyl sarcosinate (Sodium Lauroyl Sarcosinate); cocoamidopropyl betaine (Cocamidopropyl Betaine); Decyl glucoside (Decyl Glucoside) or lauryl glucoside; And D, a polar-nonpolar synergistic cleaning aid formed by polyglycerol-10 laurate (Polyglyceryl-10 Laurate) and isododecane (Isododecane), wherein the polyglycerol ester improves the flushing property of an oil phase, and the isododecane reduces the greasiness and improves the dissolution efficiency of a sun-proof oil film. (2) Microcomplexing foam stabilizing system: The double complexing system (the total amount is extremely low) of sodium gluconate (Sodium Gluconate) +sodium phytate (Sodium Phytate) is introduced into a mild formula and is used for complexing hard water ions, so that the inhibition of Ca 2+/Mg2+ on foam and cleaning efficiency is remarkably reduced. Compared with single EDTA, the system can obviously improve the hard water foam retention at low addition amount, and has lower skin irritation and better formula compatibility. (3) Reversible network thickening system: Adopts a composite thickening mode of sectional neutralization of xanthan gum (Xanthan Gum) +acrylic ester crosslinked polymer (such as A
