Problems solved by technology

[0003] Traditional soap, whether it is transparent or white soap, is basically made of oil or fatty acid as raw material through saponification and high-temperature reaction processing. This kind of ordinary soap has good cleaning power, but the pH value is generally high (pH= 9-11), more irritating, not resistant to hard water, easy to form soap scum and other shortcomings

Abstract

The invention discloses weakly acidic transparent soap and a preparation method thereof. The acidic transparent soap comprises: 30 to 50wt% of N-cocoyl-L-glutamic acid, 10 to 30wt% of one or more polyalcohols, 0 to 10wt% of ethanol, 0 to 10wt% of cane sugar, 0 to 10wt% of one or more plant additives, an alkali liquor for adjusting a pH value to 5.0-6.5, and the balance water. A cleaning component of the weakly acidic transparent soap mainly comprises an amino acid surfactant having weak acidity similar to the acid-base property of the human skin and thus the acidic transparent soap is mild, safe and no irritation, can produce rich foam in washing, and has good detergency and good hard water resistance. Through utilization of the one or more plant additives, the weakly acidic transparent soap has functions of preserving moisture, tendering and whitening skin, eliminating wrinkles, diminishing inflammation, and promoting skin regeneration. The weakly acidic transparent soap obtained by the preparation method has good transparency and hardness satisfying transparent soap industry standards.

Description

technical field [0001] The present invention relates to a kind of weakly acidic transparent soap and its preparation method, especially to a kind of weakly acidic transparent soap with amino acid surfactant N-cocoyl-L-glutamic acid as the main raw material and its preparation method. Soaps fall into the category of personal skin cleansers. Background technique [0002] At present, most of the personal skin cleansers such as shampoos, facial cleansers, and shower gels on the market use traditional surfactants, such as AES, SLS, and 6501. This kind of raw material has the characteristics of perfect formula, strong cleaning power and low price, so it is adopted by most daily chemical companies. However, in recent years, safety issues in the cosmetics industry have also become increasingly severe. The "dioxane" incident exposed in shampoos in recent years and the problem of formaldehyde in preservatives are related to the raw materials used. The daily chemical industry has bro...
