Problems solved by technology

However, due to their good hydrophobicity, such cosmetics are difficult to clean and easy to remain. Long-term use can easily cause adverse effects such as clogged skin pores and poor skin breathing.
Not only that, due to the limitations of its production process, the existing mica powder for cosmetics often has defects such as rough hand feeling, poor gloss, low transparency, and inconspicuous ultraviolet shielding effect.

Abstract

The invention discloses an organic matter coating method of mica powder used for cosmetics. The organic matter coating method of mica powder used for cosmetics comprises the following steps: mixing dimethicone, a silane coupling agent and a suspension prepared from the mica powder, carrying out wet grinding, carrying out hydrophobic treatment on the mica powder, adding a cationic surfactant under a weak acidic condition, treating the mica powder, carrying out alcohol precipitation to remove impurities and adding nanometer titanium dioxide to effectively enhance the ultraviolet shielding effect of the mica powder. The obtained mica powder has the advantages of smooth hand feeling, good gloss, high transparence and obvious pearlescent effect, effectively avoids the defects of difficult cleaning and easy residual in the prior art, has the characteristics of waterproofing, lasting property, easiness in cleaning and no residual, has good bacterium preventing and ultraviolet shielding effects, has extremely good endophilicity and skin friendly property, is safe without irritation, can be widely applied to the field of cosmetics, and is worth promoting.

Description

technical field [0001] The invention relates to the technical field of mica powder, in particular to a method for compounding organic matter with mica powder for cosmetics. Background technique [0002] Mica powder is a non-metallic mineral containing various components, mainly SiO 2 , the content is generally around 49%, Al 2 o 3 The content is about 30%; mica powder has good elasticity, toughness, insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, strong adhesion and other characteristics. Mica powder is an excellent additive, which is widely used in electrical appliances, welding electrodes, rubber, plastics, papermaking, paints, coatings, pigments, ceramics, cosmetics, new building materials and other industries. It has a wide range of uses. Due to its unique pearlescent effect, crystal transparency, silky luster and smooth texture, mica powder has excellent affinity and skin-adhesiveness with the skin. Mica powder is widely use...
