How to distinguish between soap based facial cleanser and amino acid facial cleanser?

2023-09-27 13:44

currently on the market cleanser composition can be divided into two categories.
 
The first category is a saponification formula containing facial soap ingredients; the second category is a formula that does not contain soap at all and uses synthetic surfactants as the main ingredient.
Our skin is weakly acidic, with a PH value of about 5.5. The saponification formula of facial cleansing products is made by reacting various fatty acids with strong alkalinity. The PH value is about 9~10, which has strong cleaning power, but it is quite irritating to the skin. Long-term use will wash away too much sebum, make the skin lose its protective barrier, cause great damage, and make your skin too sensitive, very prone to redness and dark spots.
The amino acid facial cleanser uses a weakly acidic amino acid surfactant, the PH value is close to the human skin, and the amino acid is the basic substance that constitutes the protein, so it is gentle and skin-friendly. Low stimulation, pregnant women, children and sensitive skin can be used.


 


 
How to judge whether the facial cleanser is saponified or amino acid? Understand the ingredients, it is no longer difficult.
1. if in the composition table, if the "fatty acid and alkali agent" at the same time, is the saponification formula. The list is as follows:
Fatty acid (Fatty acid)
1. Tetradecanoic acid/myristic acid (Myristicacid)
2. Dodecanoic acid/lauric acid (Lauricacid)
3. Hexadecanoic acid/palmitic acid (Palmiticacid)
4. Octadecanoic acid/stearic acid (Stearicacid)
alkali agent
1. Sodium hydroxide (Sodiumhydroxide)
2. Potassium hydroxide (Potassiumhydroxide)
3. Triethanolamine (Triethanolamine)
4.AMP(2‐Amino‐2‐methylpropanol)
 
2. typical amino acid table active ingredients: the general name is preceded by an acyl group, the middle is the name of an amino acid, and the last is sodium or potassium. For example, the most common amino acid surfactants are:
1.Sodium cocoyl glutamate: sodium cocoyl glutamate
2.Disodium cocoyl glutamate: cocoyl glutamate disodium
3.Sodiumlauroyl glutamate: sodium lauroyl glutamate
4. Tea‐cocoyl glutamate: cocoylglutamic acid TEA salt
5.Potassium cocoyl glutamate: potassium cocoyl glutamate
6.Sodium cocoyl glycinate: sodium cocoyl glycinate
7.Potassiumcocoyl glycinate: potassium cocoyl glycinate
In short, anyone who sees a long list of ingredients in the ingredient list that contain glutamate (glutamic acid) and glycinate (glycine) can look at them carefully. If there is no soap base and other stimulating surfactants, then this facial cleansing is very OK.
The main ingredients of Langxi amino acid foam facial cleanser are: potassium cocoyl glycinate, sodium lauroyl glutamate, cocamidopropyl betaine, etc., which can effectively remove pore dirt residue, moisturize and repair at the same time, solve the problems of large pores and rough skin, and make the skin more smooth and clear, tender and moist, and radiant.
