Problems solved by technology

[0005](1) The foaming power is poor, which is quite different from the requirements of consumers for facial cleansing soap. The foaming power is poor, so that manufacturers need Dispenses lathering net to create friction and increase lather
[0006](2) The chain length is single, and the hardness of the soap is low, which makes the soap easy to soften during use and not durable
[0007](3) Long production time: the preparation process of general transparent soap is to mix glycerin and water, heat to dissolve lauroyl glutamic acid, and then drop triethanolamine to neutralize , add other ingredients and mix evenly, cool down to 70°C and discharge, and then pour into molding
The hardening speed of amino acid soap is very slow, and it takes the next day to be demoulded, which is not conducive to continuous operation and is not suitable for large-scale industrial production

Abstract

The invention discloses a weakly-acidic high transparent soap which is mainly prepared from amino acid surfactant, humectant, neutralizer and deionized water, wherein the amino acid surfactant comprises glutamic acid surfactant, glycine surfactant and sarcosine surfactant; and based on the total mass of the weakly-acidic high transparent soap, the mass percent of the glutamic acid surfactant is 25-30%, the mass percent of the glycine surfactant is 8-10%, and the mass percent of the sarcosine surfactant is 5-8%. The invention also discloses a preparation method of the transparent soap. The pH value of the weakly-acidic high transparent soap is close to that of the skin; and the weakly-acidic high transparent soap has moderate degreasing power, does not hurt the skin, is easy to foam and can produce abundant foam.

Description

technical field [0001] The invention relates to a weakly acidic high-transparency soap. At the same time, the invention also relates to a preparation method of the highly transparent soap. Background technique [0002] Traditional soap cleansing products use fatty acid as the main ingredient, and alkali is added to neutralize the fatty acid until pH=9.0 to obtain transparent fatty acid soap. Fatty acid soap has the advantages of easy cleaning, non-greasy, and refreshing skin feeling after washing, and is favored by young consumer groups. Amid the calls for returning to nature, the sales of soaps derived from natural fatty acids are growing by leaps and bounds. However, fatty acid soap is strongly alkaline, with a pH value of about 9.0, which is quite different from the weakly acidic pH value of the skin at about 5.3. The degreasing power is very strong. After washing, the skin becomes dry and the pores become thicker, which is easy to cause skin itching especially in autumn...
