Highly translucent pure amino acid self-thickening cleansing soft gel and preparation method thereof

Abstract

The invention discloses a high-light-transmission pure amino-acid self-thickening soft cleansing gel, which is characterized by being composed of the following raw materials: potassium cocoyl glycinate, potassium n-lauroylsarcosinate, sodium lauroyl sarcosine, potassium lauroyl taurine, sodium cocoyl malic amino-acid salts, sodium lauroyl oat amino acids, palmitoyl hydrolyzed wheat proteins, dipotassium glycyrrhizate, trimethylglycine, glycerin, sodium citrate, sodium chloride, plant essential oil and purified water, and high-consistency products are efficiently prepared by using a conventional equipment according to a cooling method. According to the invention, deficiencies in the prior art are overcome, the pure amino-acid self-thickening soft cleansing gel which is provided by the invention is convenient to prepare, good in stability, dense in foam, comfortable in skin feeling and looks shining bright and is free of preservatives; and if products are taken into the human body by accident, because body metabolic intermediate and final products of the cleansing gel are in the range of foods, so that the health is not damaged.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a self-thickening cleansing soft gel of pure amino acid in a highly transparent state. The invention also relates to a preparation method of a high light-transmitting pure amino acid self-thickening cleansing soft gel. Background technique [0002] With the acceleration of the modernization process, the classic three-step concept of skin care (cleaning, clearing the skin and moisturizing) has been popularized from fashionable women to the general public. That is, people pay more attention to air pollution and try to reduce the damage of polluted air to facial skin by using cleansing products. Like this, since skin cleansing plays a vital role for beauty treatment as a basic step, a large number of cleansing series products represented by facial cleanser derived from petrochemical raw materials are on the market. [0003] But the grim fact is that while people are wid...

Problems solved by technology

[0005] ①The thickening of amino acid surfactants is extremely difficult, and there is still no effective special thickener. Although some sodium fatty acyl lactyl lactylate and fatty alcohol lactate can help thicken the amino acid surfactant system, but the effect Limited, it is extremely difficult to make a soft gel; the popular amino acid facial cleanser series on the market still rely on the traditional fatty alcohol polyoxyethylene ether sulfate (or fatty alcohol phosphate) + fatty acid ethanolamide (or amine oxide and betaine) ) system thickening, some even rely on acrylic acid series polymer thickeners, amino acid surfactants are only supporting roles, and the negative effects of many synthetic compounds on the skin cannot be avoided;

However, this technical solution still relies on the acrylic acid (ester) copolymer derived from petrochemical raw materials as the leading role of the thickener, and methyl cocoyl taurate and triethanolamine salt are also related to petrochemical products, which cannot be decomposed or The requirement that the intermediate products of human metabolism belong to the scope of food

In addition, the existence of trihydroxystearin and polyhydroxystearic acid leads to defects such as poor low-temperature transparency and easy layering of the product

[0008] ④Precisely purified cocoyl glycinate or lauroyl glycinate and other amino acid surface activities can be adjusted into a high-viscosity system with electrolytes such as sodium chloride, but the transparency of the high-viscosity system is poor, and fine particles are easily precipitated after long-term storage , the water solubility becomes poor at low temperature and turns turbid, the consistency decreases, and the skin is astringent after washing, so it is difficult to commercialize

[0009] To sum up, so far, the industry has not yet developed a pure amino acid self-thickening cleansing soft gel with good stability, fine foam, comfortable skin feeling, and high light transmission.
