Protects skin Imparts a soft, velvety skin feel Easily distributed on skin and hair Soap removal (prevents foaming during wiping off) Adding silicone oil to cosmetics improves moisturizing and protective effects on skin, etc.

Colorless transparent volatile liquid, very stable in nature, smooth to the touch, with a good sense of gloss and softness, used in cosmetics, especially in sunscreen products, can reduce the greasy feeling, clear and natural. It is breathable, does not block pores, forms a protective film, and gives the skin a dry and soft afterfeel, lubricity, dispersibility, and breathability, and is also used in hair care products.

 

 

 

 

 

 

 

 

 

 

According to the experimental situation, the charged condition of the pigment in the paint is summarized: a. The charged solvent of the pigment has less influence than the resin. b. Inorganic pigments are prone to change in charge polarity depending on the conditions of the resin and surfactant, and are positively charged in the acid resin solution. c. Organic pigments do not change the charged polarity due to resins and surfactants.

Disperse organic pigments and inorganic pigments in alkyd resins and amino resins. Phthalocyanine blue does not change the charging polarity due to changes in the resin. TiO 2 changes the charged polarity with the change of the resin. Most organic pigments have a positive charge for the electron donating substitution group and a negative charge for the electron accepting substitution group.

The resin and surfactant in the paint contact with the pigment to adsorb, and the adsorbed molecules and the pigment surface undergo electrons or protons. As a result, part of the adsorbed molecules are separated or dissociated, and the pigment particles are charged. Generally, wax additive mst metal oxides like TiO have amphoteric properties, and when contacted with acidic alkyd resins, they become alkaline and positively charged; when contacted with basic amino resins, they become acidic and negatively charged. Organic pigments are positively or negatively charged according to the strength of the electron donating and accepting substitution groups, and do not change with the polarity of the resin molecule.
