Technical Field

The invention belongs to the field of cosmetic base materials, and particularly relates to silver ion and infrared combined membrane material base cloth and a preparation process thereof.

Background

Titanium dioxide (TiO)₂) The cosmetic has the advantages of high stability, low cost and the like, is widely used in the field of cosmetics in the twentieth century, becomes one of main raw materials for cosmetic production, mainly plays a role in physical covering, and is often used for foundation, sunscreen cream, blusher, facial mask and the like. With the intensive research on skin cancer in medicine and the wide use of sunscreen products, TiO₂Is more reputed as the most environment-friendly sun-screening material in modern times. With the development and progress of science and technology, TiO₂Nanometer-level and nanometer-level TiO has been made from micron-level₂Because the particle size is small and the activity is high, the ultraviolet light can be reflected and scattered and absorbed, and the ultraviolet light has stronger barrier capability; TiO 2₂The smaller the particle size, the stronger the covering power, the existing nano TiO₂Light waves capable of absorbing infrared rays have been made; at present, the cosmetics with various famous brands are used as the marks of modern product science and technology.

The nano-sized powder can penetrate into every corner of the skin, but simultaneously can penetrate into the subcutaneous tissue layer through the absorption of the skin, and the nano-sized TiO powder can penetrate into the subcutaneous tissue layer through the absorption of the skin₂After entering the skin, the water-absorbing agent has strong water absorption, and after water absorption and expansion, the water-absorbing agent is retained in the skin and even attached to pore walls, and is difficult to be excreted by skin metabolism. Lead consumers to use foundations, blushes, sun screens or concealers, etc. containing nano TiO₂The cosmetic has the problems of skin acne, pore blockage, even cell blockage of various biological channels, poor skin air permeability, even black spots on the surface and the like after a period of time, and the skin slowly has no sensitivity to the change of the external environment, even the epidermis is hardened, thus affecting the absorption of moisture and nutrition.

The existing cosmetic cleaning products are mainly produced by using raw materials of acid, alkali and alcohol, and the products have side effects on skin in different degrees; and nano TiO₂It is resistant to acid and alkali, has no excessive reaction to acid and alkali, and is difficult to be cleaned from deep skin layer by using various facial cleansers or other cleaning agents. Therefore, there is an urgent need for a new composition that can help remove residual TiO from the skin₂And other impurities.
