Liquid cleansing composition and its preparation method and application

Abstract

The invention relates to a liquid skin-cleansing composition. The liquid skin-cleansing composition is prepared from the following raw materials in parts by weight: 3.0-15.0 parts of natural grease, 18.0-27.0 parts of fatty acid, 6.0-8.0 parts of potassium hydroxide, 0.2-3.0 parts of a non-ionic surfactant, 0.1-3.0 parts of brown sugar, 1.0-5.0 parts of potassium cocoyl hydrolyzed avenin, and 50.0-60.0 parts of water; and the non-ionic surfactant is a composition of PEG / PPG-80 / 20 copolymers, PEG-32 and PEG-6. The liquid skin-cleansing composition is low in viscosity and is conveniently taken for use, and the liquid skin-cleansing composition is added into cleaning products and is easy to rinse, the dry and tight body feeling is avoided, rich foam can be formed, and the foam amount of the liquid skin-cleansing composition is not affected even if the liquid skin-cleansing composition is used in hard water.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to a liquid cleansing composition and its preparation method and application. Background technique [0002] Traditional soap is prepared by the reaction of oil and sodium hydroxide. The main raw materials of oil are tallow, lard and other animal fats, which are boiled and then neutralized. The traditional soap making method is called "soap boiling", that is, the reaction time is very short. Long, and difficult to industrialized mass production. The lye used in traditional soap making is sodium hydroxide, and the amount must be excessive to ensure that the oil is converted into soap. Therefore, its pH is 11-12, which is strong in alkalinity, and the skin is relatively dry after washing, which is very irritating to the skin. [0003] With the change of social needs, consumers are eager for mild and healthy products. In order to solve the problem of irritating traditio...

AI Technical Summary

Problems solved by technology

However, the saponification reaction time is slow, the purification time is long, and it is difficult to mass-produce completely, because the use of oil saponification into handmade soap can only exist in the form of solid, and the current cleaning products are in various forms, such as: cleansing Mousse, bubbles, facial cleanser, facial cleanser, etc., handmade soaps are single in form and easily polluted after repeated use, which cannot meet the diverse needs of washing products

[0004] In order to increase the speed of saponification and obtain liquid soaps that are easier to use, soaps are currently prepared in daily cosmetics factories mainly through the saponification of fatty acids and lye. Only the fatty acids that have been refined from oils are used to react with lye, and the natural ingredients in oils cannot be retained. Therefore, most products can only be used to clean clothes, tableware, etc.; it is very difficult to directly use oil to participate in the reaction to produce soap, and the viscosity of the soap reaction is too high. Large, difficult to stir, the final viscosity of the product is unstable, crystallization is easy to precipitate at low temperature, the transparency is not enough and easy to be turbid, and free alkali is difficult to control, resulting in increased irritation

At the same time, its preparation time is relatively long, energy consumption is relatively large, and the process is complicated, and the stability of product batches is difficult to guarantee.
