In addition to the general ingredients, drugs and pharmaceutical are often added in cosmetics. Many pharmaceutical not only have medicinal value, but also can add nutrients which are lacking in skin. So these agents are also known as nutritional raw materials.
Vitamin A has the function of absorbing ultraviolet light. The molecular structure of vitamin A contains long conjugated double bond biotin system. In the conjugated system, electron can absorb into the 290 ~ 400nm ultraviolet and produces vitamin A which can prevent epidermal cell keratinization and has a good effect on the freckles.
Bone collagen amino acids susceptible to collagen in the skin absorption, made of paste rub with a very comfortable feeling. And this role of the original soluble glue to protect the skin moisture, have a significant effect of moisturizing the skin, prevent skin aging, and cosmetics can make pigment containing collagen was significantly diminished, reduce facial wrinkles, chapped effect of the treatment of hand and foot.
Aloe preparations can enhance the ability of the skin stratum corneum adsorption and bound water molecules, make the loss of elasticity of dry skin dry stratum corneum hydration, and restore the original skin smooth, soft and good elasticity. Aloe contains a variety of pharmaceutical ingredients, tretinoin, bioactive substances, nutrients, etc., rough skin, and have special effects, facial wrinkles, scars, freckles, acne and other skin and hair has a protective effect, aloe extract for cosmetic additives made sunscreen, in addition to effectively prevent the darkening of the skin caused by sun exposure and skin inflammation and skin, but also to prevent the UV rays.
At present, these natural raw materials of animal and plant extracts, as well as a variety of Chinese herbal medicine have drawn increasing attention. An increasing number of natural raw materials are developed and applied to a variety of cosmetics. In the future, for a long period of time, natural development and utilization of raw materials will be a trend of cosmetic development.Source:http://www.cosprm.com

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.
