Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of daily cosmetic production, in particular to a dispersion emulsification composition, a preparation method and a cleansing composition. BACKGROUND

[0002] The main components in the current mainstream cleansing product formula on the market are fatty acid salts or amino acid salts and other surfactants. During the dispersion and dissolution of such surfactants in water, if the dispersion is not timely, the surfactants will aggregate, the hydrophobic groups will closely aggregate and arrange inward, which will easily cause soap glue during the dissolution process. Therefore, dispersion can only be achieved under the conditions of high temperature, high-speed stirring and long time, and the production efficiency is low. Moreover, if the reaction is not uniform during the production process of a high-activity formula, the final stability of the product will be affected, and in addition, there will be more foam during the production process, which will cause the final product to have problems such as density reduction and unstable tank quality. On the other hand, the dispersants currently used in the dispersion emulsification composition, the preparation method and the cleansing composition are polyols such as glycerol, propylene glycol, butylene glycol and polyethylene glycol. When such polyols are used as dispersants, they account for a large proportion in the formula, which limits the overall active material concentration of the formula. At the same time, propylene glycol and butylene glycol have high dispersion efficiency, but when they are added to the formula, they will make the crystal loose, the surface rough and discontinuous, and will reduce the viscosity of the foam film, causing the foam to be unstable and easy to disappear.

Comparative Examples 1', 3', 5', 8', 9', 10' are placed at 45°C, the cream body has a delamination phenomenon, and the bottom or local part has a liquefied transparent state. When placed at low temperature, the material body becomes hard, and the application has a roughening phenomenon. Therefore, the emulsified and dispersed composition with different proportions will affect the stability of the final product when applied.

[0098] The specific method is as follows: the samples are given to 20 test personnel for comparison. The test personnel use the samples using the same method for cleaning, and each sample is used for two weeks, and the testers score according to their own feelings. The scoring adopts a 7-point system, 1 point being the worst, 4 points being general, and 7 points being the best.
