There are always friends around me who ask me to analyze the ingredients of various facial cleansers. I carefully read its formula list and reviewed all the surfactants used in it from the chemical structure to formula performance ( In addition to the main detergent, it also includes all moisturizing builders), which are now treasured by everyone, and their irritating properties are specially arranged in order - soaps>I-level anions>II-level anions>III-level anions>zwitterionics ≥Non-ionic. There are roughly three types:
Class I anionic surfactant - the poor thing that has been demonized by marketing
Ingredient list: sodium lauryl sulfate (actually the one you hate the most) SLS (sometimes also called sodium cocoyl sulfate), sodium cetearyl sulfate, sodium trideceth sulfate, sodium laureth sulfate (also criticized SLES).
Level II anionic surfactants - the amino acid surfactants you are crying for every day: sodium cocoyl glutamate, potassium cocoyl glutamate, sodium myristoyl glutamate, Sodium methyl cocoyl taurate, sodium cocoyl glycinate, sodium cocoyl sarcosinate, cocoyl glutamic acid TEA salt, potassium cocoyl glycinate, sodium lauroyl glutamate, lauroyl sarcosine Sodium cocoyl taurate, sodium cocoyl methyl taurate, sodium stearoyl glutamate, sodium lauroyl aspartate, sodium palmitoleoyl glutamate?
Class III anion Surface activity - anions that have always been soy sauce in the eyes of the public but have excellent actual performance
Disodium laureth sulfosuccinate, sodium cocoyl isethionate, lauryl alcohol Disodium sulfosuccinate, sodium lauryl glucose carboxylate, sodium C14-16 olefin sulfonate, sodium isostearyl lactyllactate, sodium lauryl glycol carboxylate.
