Problems solved by technology

Generally, powders are rarely added to oil-in-water cosmetics (including but not limited to colorants, sunscreens, fillers, pearlescent agents, etc.), because the powders are relatively small in size, large in specific surface area, and have active surface electrons. It has high surface activity, and it is easy to agglomerate, condense polymers, and destroy the emulsified interface, resulting in product quality problems such as uneven dispersion, rough paste, and even layering.
[0004] In oil-in-water cosmetics, due to the active electrons on the surface of the untreated powder, it has high surface activity and tends to gather in the water-oil interface, making the powder not well dispersed.
Although the use of treated powder can reduce its surface activity, due to the different processing technology levels of various suppliers, it is difficult for the hydrophobic / oleophobic treated powder to be completely covered by the treatment agent, and the exposed parts of the powder surface are still Dispersion is prone to problems such as agglomeration, coagulation of polymers, and damage to the emulsified interface
[0005] CN109069354A discloses an oil-in-water type solid cosmetic in the prior patent technology, including hydrophobically modified polyether urethane, hydrophilic plate-shaped powder, hydrophobic powder, oil and water; Wetting effect, but poor in system stability
It is not conducive to consumer use and affects its performance
[0006] Therefore, in summary, the oil-in-water cosmetics of the prior art mainly have the problem of system stability, and the use effect is affected at the same time due to the state of the system during use.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a powder-containing oil-in-water cosmetic composition and a preparation method thereof. Background technique [0002] Cosmetics refer to smearing, spraying or other similar methods that are spread on any part of the human body surface, such as skin, hair, nails, lips and teeth, etc., to achieve cleaning, maintenance, beauty, modification and change of appearance, or to correct human body odor, maintain Chemical industrial products or fine chemical products for the purpose of good condition. In recent years, consumers have paid more and more attention to the skin feel of cosmetics, and cosmetics that are moisturizing, cool and easy to apply are welcomed by the market. Oil-in-water cosmetics are emulsification systems in which oil is dispersed in water, with oil as the inner phase and water as the continuous outer phase. When coating, the outer phase is the water phase compon...
