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

Embodiment 1-6

[0079] Table 1 is the formulation of the liquid skin cleansing compositions of Examples 1-6.

[0080] Its preparation method of the liquid cleansing composition of embodiment 1-6 is as follows:

[0081] The raw materials required for each embodiment were weighed in parts by weight shown in Table 1.

[0082] Mix natural oil, fatty acid, part of water, PEG / PPG-80 / 20 copolymer, PEG-32 and PEG-6, heat to 50-65°C, stir until it completely dissolves and becomes a dilute solution, and keep a vacuum of -0.05 ~0.2Mpa;

[0083] Mix potassium hydroxide with some water to form a potassium hydroxide solution with a concentration of 40%, slowly add it dropwise to the mixture in the previous step step by step, and keep the vacuum at 0.2Mpa, the temperature is 60°C, and configure a condensation reflux device At the same time, turn on the fast dispersing device, keep the dispersing speed at 3000rpm, add cocoyl hydrolyzed oat protein potassium, brown sugar, stir until dissolved, until the mat...

Embodiment 1 and comparative example 1-4

[0087] Table 2 is the formula of the liquid cleansing composition of Example 1 and Comparative Examples 1-4.

[0088]

[0089]

[0090] The performance test of embodiment 1-6 and comparative example 1-4

[0091] Test 1 basic physical and chemical performance test.

[0092] Wherein, the testing method of the viscosity is: the composition is kept warm at 25° C. in advance, and the NDJ-5S / NDJ-8S rotational digital viscometer is used for measurement.

[0093] The test results are shown in Table 3.

[0094] table 3

[0095]

[0096]

[0097] It can be seen from Table 3 that the liquid cleansing compositions prepared in Examples 1-6 are clear and low-viscosity transparent aqueous solutions, which are easy to extract when used as basic cleaning materials, and can be applied to transparent and opaque products. Products in various states such as liquid, paste, and emulsion. It is easy to stir evenly during the production process, and it only takes 1 to 2 hours from th...

Embodiment 1＇、 Embodiment 4＇- Embodiment 6＇ and comparative example 1＇- comparative example 4

[0100] The compositions of Examples 1, 4-6 and Comparative Examples 1-4 are prepared into shower gels, corresponding to Example 1', Example 4'-Example 6' and Comparative Example 1'-Comparative Example 4', Its formula is shown in table 4.

[0101] The shower gel is prepared as follows:

[0102] The raw materials required for each embodiment and comparative example were weighed in parts by weight shown in Table 4.

[0103] Add disodium edetate and sodium chloride to water at a temperature of 25°C and stir until dissolved to obtain a transparent solution A;

[0104] Add the corresponding liquid cleansing composition, sodium cocoamphoacetate, 1,2 propylene glycol, ethylene glycol distearate, cocamidopropyl betaine, sodium lauroyl sarcosinate, PEG into the transparent solution A -14M, and methylparaben and propylparaben, heated up to 50-60°C, stirred until dissolved, and obtained solution B;

[0105] Add citric acid aqueous solution to solution B, cool down to 45°C, add cocoyl d...

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...
