Novel skin-cleansing soap and preparation method thereof

Abstract

The invention provides a novel skin-cleansing soap and a preparation method thereof. The novel skin-cleansing soap comprises, in parts by weight, 60-85 parts of alpha-hydrogenated tallow fatty acyl amide pentyl-N,N-dimethyl betaine, 3-9 parts of glycerol monooleate, 1-5 parts of stearic acid diethanolamide, 2-7 parts of lauryl diethanolamide, 2-6 parts of hexadecanol, 4-10 parts of sodium olefin sulfonate, 1-4 parts of imidazolidine, 2-9 parts of dodecay diethanol amine sulfate, 3-7 parts of sodium chloride, and 5-12 parts of deionized water. The preparation method of the soap comprises: firstly mixing alpha-hydrogenated tallow fatty acyl amide pentyl-N,N-dimethyl betaine, glycerol monooleate and stearic acid diethanolamide, stirring and then adding the other compositions, uniformly mixing and heating for fusing, and then pouring into a mold, naturally reacting and demolding, so as to obtain a finished product. The obtained skin-cleansing soap is relatively small in influence to sebum membrane, moderate in hardness, and fine and abundant in foam. After the soap is applied to skin, original acnes and pimples are obviously mitigated.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to a novel cleansing soap and a preparation method thereof. Background technique [0002] Cleansing soap is a daily washing product. Its main ingredient is sodium fatty acid, and its main function is to remove dirt, skin secretions, excretions, chemicals or bacteria on the surface of the skin. Because fatty acid sodium has a hydrophilic end (carboxyl end) and a lipophilic end (hydrocarbon end), the lipophilic end can be dissolved in fat-soluble dirt, and the hydrophilic end can be dissolved in water, so that the dirt can be wrapped into small groups for cleaning in the water. [0003] Cleaning ability is an important indicator to measure the quality of cleansing soap. However, since the pH value of healthy skin should be maintained at 4.5-6.5 in a weakly acidic state, sodium fatty acid itself is a weakly alkaline substance with a pH value of around 10. Many...
