Problems solved by technology

The usual water-in-oil system liquid foundation has a greasy skin feel, poor air permeability, oily appearance, unnatural makeup, and long-term use can easily cause pore clogging
Oil-in-water products can solve these problems to a certain extent, but they often have problems such as poor stability, easy delamination, and sedimentation; general oil-in-water system liquid foundations solve these problems by adding emulsifiers or surfactants, but Emulsifiers and commonly used surfactants are likely to irritate sensitive skin and make liquid foundation products feel thicker

Embodiment 1-3

[0057] Adopt the formula listed in Table 1 to prepare the dispersion type liquid foundation provided by Example 1, Example 2 and Example 3.

[0058] Table 1 Recipe table

[0059]

[0060]

[0061] The preparation method is as follows:

[0062] Preparation of the aqueous phase:

[0063] (1) Polyacrylate cross-linked polymer-6 is pre-dispersed evenly with cold water and set aside;

[0064] (2) p-Hydroxyacetophenone is dissolved by heating with a small amount of propylene glycol, for subsequent use:

[0065] (3) Put deionized water, propylene glycol and (1) into the emulsification pot, stir and heat up to 90-95°C, moderately homogenize, dissolve evenly, keep warm for 10 minutes, and vacuum defoam; add (2) and stir evenly, then add methyl Gluceth-20 and phenoxyethanol are stirred evenly; the pH and viscosity are measured, and after passing the test, keep warm at 90-95°C and set aside;

[0066] Oil phase preparation:

Abstract

The invention provides dispersible liquid foundation and a preparation method thereof. The liquid foundation is prepared from 4-6 parts of a moisturizer, 0.2-0.5 part of a water-phase thickener, 1-4 parts of a skin conditioner, 4-8 parts of an emollient and 0.9-2.5 parts of an oil-phase thickener, wherein the water-phase thickener comprises a polyacrylate cross-linked polymer-6, the oil-phase thickener comprises magnesium stearate, C30-45 alkyl polymethylsiloxane / C30-45 olefin and cyclopentasiloxane / disteardimonium hectorite / propylene carbonate. The preparation method of the liquid foundation comprises steps as follows: the moisturizer, the water-phase thickener, the skin conditioner, the emollient and the oil-phase thickener are mixed with water uniformly. The provided liquid foundationmakes skin refreshing and has good lasting property and special appearance state.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a dispersed liquid foundation and a preparation method thereof. Background technique [0002] In terms of its microscopic state, cosmetics are generally divided into two types: oil-in-water and water-in-oil. The usual water-in-oil system liquid foundation feels greasy on the skin, has poor air permeability, is prone to oil production, has an unnatural makeup feel, and long-term use can easily cause pore clogging. Oil-in-water products can solve these problems to a certain extent, but they often have problems such as poor stability, easy delamination, and sedimentation; general oil-in-water system liquid foundations solve these problems by adding emulsifiers or surfactants, but Emulsifiers and commonly used surfactants are likely to irritate sensitive skin and make liquid foundation products feel heavy on the skin. [0003] In view of this, this application is proposed. Contents of th...
