Problems solved by technology

However, because fatty acid sodium has a certain degree of alkalinity, after washing with soap, the pH of the skin surface will increase greatly, which will cause certain allergies to highly allergic skin, and will also wash away the lipid layer on the skin surface, making the skin Dry

Embodiment Construction

[0007] Mix sodium hydroxide and water into the reactor, stir and heat to 68 degrees, add lauric acid and oleic acid while stirring, and gradually add the mixture of ethylene glycol stearic acid monoester and lauroyl diethanolamine after stirring well, fully After stirring, after the reaction is complete, add ethylenediaminetetraacetic acid and methyl p-hydroxybenzoate when the temperature drops to 50 degrees, and finally add an appropriate amount of glycerin and an appropriate amount of essence. The mass ratio of the above raw materials is: sodium hydroxide: lauric acid: Oleic acid: Ethylene glycol monostearate: Diethanolamine lauroyl: EDTA: Methylparaben = 1:8:1.5:6:1.5:5:0.5.

[0008] The invention has the advantages of bringing the used raw materials to the best state, simple process operation, reduced production cost, simple process, non-toxic, harmless, pollution-free, and waste water, and achieving the purpose of environmental protection.

Abstract

The invention relates to the field of articles for daily use and particularly relates to liquid soap. The liquid soap is prepared by the following steps of: mixing sodium hydroxide and water, adding the mixture into a reactor, stirring and heating to 68 DEG C, adding lauric acid and oleic acid while stirring, gradually adding mixture of ethylene-glycol monoester stearate and lauroyl diethanolamide after stirring uniformly, after fully stirring and complete reaction, adding ethylenediamine tetraacetic acid and methyl parahydroxybenzoats when the temperature is reduced to 50 DEG C, and finally adding a proper amount of glycerinum and a proper amount of essence. The mass ratio of the materials such as sodium hydroxide, lauric acid, oleic acid, ethylene-glycol monoester stearate, lauroyl diethanolamide, ethylenediamine tetraacetic acid and methyl parahydroxybenzoats is 1:8:1.5:6:1.5:5:0.5.

Description

[0001] technical field [0002] The invention relates to the field of daily necessities, in particular to a liquid soap. Background technique [0003] The main component of soap is sodium fatty acid, which is basically saponified from oil, has no toxic side effects on the human body, and is easily degraded by the environment; therefore, it can be said that soap is a "natural" green product. However, because fatty acid sodium has a certain degree of alkalinity, after washing with soap, the pH of the skin surface will increase greatly, which will cause certain allergies to highly allergic skin, and will also wash away the lipid layer on the skin surface, making the skin Dry. Existing scented soap is all solid scented soap. Contents of the invention [0004] In view of the above technical problems, the object of the present invention is to provide a liquid soap. [0005] The technical solution to be solved by the present invention is as follows: mix sodium hydroxide and wa...
