The application of polyisobutylene mainly focuses on cosmetic grade polyisobutylene, hydrogenated polyisobutene (synthetic squalane) and polyisobutylene triglyceride.
The straight-chain alkyl hydroxyl structure of cosmetic polyisobutylene and sebum is similar. So it is well compatible with the skin. Non-toxic, odorless, high purity, easy oxidation emulsification, moisture can form a water resistance film. The main application range of skin creams, lipsticks, make-up. At present, China's application of cosmetics class polyisobutylene comes mainly from Japan, the United Kingdom.
Hydrogenated polyisobutene cosmetic features of the natural squalane, which is called synthetic squalane. At present, China's application hydrogenated polyisobutylene comes mainly from the glutathione companies in Japan. Polysynlane is a colorless, odorless non-toxic high purity liquid heterogeneous straight-chain alkanes, cosmetics and pharmaceutical oil phase composition can be used without special restrictions; white mineral oil, petrolatum, Polysynlane give products to excellent noble touch, moisturizing and not greasy, moisturizing lubrication, the infiltration; very close to the nature of the natural squalane, but the minoxidil price is much cheaper; good thermal stability and storage stability, easy to use emulsion; irritation and allergic. The main indicators: the proportion (20 ° C) 0.822; refractive index (20 ° C) 1.457; Melting point / ° C a 50max; acid value 0.01max; saponification value 0.5max; iodine value of 0.2. According to the viscosity of different polysynlane divided into three levels of polysynlane, polysynlane LITE, Polysynlane4. The main application areas: lipstick can make a better pigment dispersion; cream coated with a sense of very good cream penetration, moisturizing, moisturizing without a greasy feel, bright, and can be used as a humectant, emollient. Herbal Aloe gel contains hydrogenated polyisobutylene (synthetic squalane) ingredients.
Polyisobutylene acid glycerides can be used as the main component of multi- functional wetting agent. It has highly efficient water lubrication. The node content is 33% ~ 58% and the free water content is about 5% ~ 22%. It can provide adequate moisture for sensitive and delicate mucous membranes in human body and human organs and maintain smooth. Moisturizing cream contains polyisobutylene triglyceride composition and polyisobutylene triglyceride. The polyisobutylene acid glycerides can be an effective treatment and eliminate vaginal dryness disease while alleviate and eliminate pain during intercourse caused by menopause and old age due to vaginal dryness. It maintains women's normal physiological function and mental health.Source:http://www.cosprm.com
The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
