Problems solved by technology

However, the cleansing products with the theme of amino acid surfactants will face the following challenges in the process of technology development: 1) It is difficult to thicken and maintain long-term stability, the appearance of the product is not smooth and delicate, and water separation will occur during the shelf life
2) The high and low temperature stability is not enough, the product will be thinned at high temperature, and in the low temperature environment, the layered surface will become rougher
The high and low temperature stability of the product obtained is better, but it limits the surfactant to sodium lauroyl glutamate, which limits the large-scale production of this product due to its high price

Embodiment 9

[0060] Embodiment nine to embodiment eleven investigate the impact of amino acid compounding on product performance, the kind, content of salt (all are sodium chloride, content is 0.8wt%) and the kind, content of thickener (all are U20, content Both are 0.8wt%) remain unchanged. Using a single sodium cocoyl glycinate in Example 9, the amino acid cleanser tends to reach a higher viscosity, and its viscosity is 8280MPas, but it tends to become thicker under low temperature conditions and cause system instability. Using single potassium cocoyl glycinate in embodiment ten, the viscosity of amino acid type facial cleanser is relatively low, and its viscosity is 1900MPas, causes the high-temperature delamination phenomenon to occur easily in the product.

[0061] And in embodiment 11, under the condition of not changing total amount, adjust the proportioning ratio of sodium cocoyl glycinate and potassium cocoyl glycinate, the viscosity of the amino acid type cleansing milk that obta...

[0065] Add the thickener and deionized water into the emulsification pot, and stir to disperse it evenly, then add potassium myristoyl glycinate and sodium myristoyl glycinate in different proportions into the emulsification pot, heat to 80-85°C, Stir to dissolve for 45 minutes, and let it stand for 30-60 minutes to eliminate bubbles on the liquid surface; cool down to 45-55°C, add the corresponding neutralizer to adjust the pH value of the system; continue to cool down to 45-50°C, and add other components according to the mass ratio , continue to stir for 30 minutes and keep warm at 45-50°C to make it completely dispersed evenly. As shown in Table 5, and investigate the performance of the amino acid type cleanser prepared by different embodiments, the results are shown in Table 6.

[0077] Convert SC200 to Acrylic or Acrylates / C10-30 Alkyl Acrylate Crosspolymer ( Add SC-200Polymer, Lubrizol Additives (Zhuhai) Co., Ltd.) and deionized water into the emulsification pot, and stir to disperse it evenly, then add sodium cocoyl glycinate and potassium cocoyl glycinate into the emulsification pot, heat To 80-85°C, stir to dissolve for 45min, let stand for 30-60min to eliminate liquid surface bubbles; cool down to 45-55°C, add triethanolamine to neutralize; continue to cool down to 45-50°C, add other components according to mass ratio Continue to stir for 30 minutes and keep warm to 45-50°C to make it completely dispersed evenly. After discharging, let it stand for 12 hours to get amino acid type cleanser. The amino acid type cleanser is a milky product. The mass percentage of each component The content is shown in Table 7, and the performance of the amino acid type cleanser prepared by different embodiments is investigated, and the results are shown in Table 8....

Abstract

The invention provides an amino acid type facial cleanser which is prepared from the following raw materials in percentage by weight: 10 to 30 percent of amino acid surfactant, 0.5 to 2 percent of thickener, 0.2 to 2.5 percent of neutralizer, 0.1 to 1 percent of conditioner and deionized water. The invention also provides a preparation method of the amino acid type facial cleanser. The preparation method comprises the steps of firstly, thinning the thickener, adding the amino acid surfactant, stirring, dissolving, adding the conditioner and the like, and standing for one night, so as to obtain the amino acid type facial cleanser. The amino acid type facial cleanser provided by the invention is neutral, mild and skin-friendly, safe and non-irritant without adding burden to skin, capable of deeply cleaning the skin, and suitable for any skin and can be used for a long term, and after the skin is cleaned by using the cleanser, the skin can quickly return to oil-water balance and acid-base balance; the texture of the cleanser is emulsion appearance, and the cleanser has excellent appearance and moisture retention, excellent in high and low temperature stability, has a certain thickness and can provide good user using experience.

Description

technical field [0001] The invention belongs to the technical field of daily cosmetics, and relates to an amino acid-type facial cleanser and a preparation method thereof, in particular to a facial cleanser containing at least two amino acid surfactants and having high high and low temperature stability and a preparation method thereof. Background technique [0002] Cleansing is an extremely important step in facial skin care. If it is not cleaned, the retained oil and dirt will not only easily breed microorganisms and damage the skin, but also form a closed barrier on the skin surface, which will affect the penetration and absorption of subsequent skin care products. [0003] The traditional soap-based cleansing cream uses fatty acid soap saponified by strong alkali as the main cleansing ingredient. It has strong degreasing power. Long-term use will cause excessive loss of facial sebum, damage the stratum corneum, and cause excessive dehydration and dryness of the skin. In...
