Introduction to the seven application areas of ultrafine talcum powder-5
Talc is a white fine crystalline powder with a layered structure, smooth touch, soft texture, moderate adhesion, high whiteness and certain covering power. These characteristics make talc the most commonly used filler in powder products, and it is widely used in the manufacture of scented powder, pressed powder, talcum powder and other products.
Because Talc for the cosmetics industry has a high polarity, when dispersed in a solvent with a lower polarity, its compatibility is poor and lacks affinity, which easily leads to uneven mixing, thereby affecting the adhesion of the product and causing the problem of easy brittleness of the pressed powder. At present, most commercially available Talc for the cosmetics industry is surface treated, and the most commonly used one is triethoxyoctylsilane treatment. This treatment method can improve the waterproof performance of talc, reduce the surface activity of the powder, and thus enhance its compatibility. In addition, different surface treatment methods can also improve the suspension, dispersibility and adhesion of Talc for the cosmetics industry to the skin.
Talc for the cosmetics industry used in cosmetics has the following characteristics: it is rich in silicon and can block infrared rays, thereby improving the sun protection and anti-infrared performance of cosmetics. At the same time, the slippery properties and pearl-like luster of Talc for the cosmetics industry make it have a certain protective and beautifying effect on the skin. Talc powder is easy to clean, non-toxic and harmless, and has high safety for the human body.
