Description
Squalane is an important component of human sebum. The sebum secreted by the sebaceous glands of human skin contains approximately 10% squalene and 2.4% squalane. The body can convert squalene into squalane. Squalene can provide oxygen and nutrients to cells, promote cell metabolism, form a sebum film on the outer layer of the skin, prevent water loss, and isolate bacteria, dust and ultraviolet damage. However, from around 2Chemicalbook 5 years old, the secretion of squalene will decrease rapidly, which will lead to skin dehydration, sagging, dullness, aging and other problems. Therefore, it is very important to replenish squalane to the skin! The cosmetic effects of squalene and squalane are almost the same, but the molecular structure of squalene is unstable and easily oxidized, so it is usually packaged in capsules and suitable for oral administration; while squalane is a stable pure oil. Suitable for external use.
1. Squalane is widely used as a base material for cosmetics, finishing cosmetics, precision machinery lubricants, medical ointments, and fat-reducing agents for high-grade soaps. 2. Squalane is a natural product, inert, non-toxic, has very good affinity for human skin, and will not irritate the skin or cause allergies. It accelerates the penetration of other active substances into the skin. Squalane is an oily raw material for high-end cosmetics, such as various creams and lotions, eyeliners, eyeshadows and hair conditioners. Cosmetics mostly use natural products extracted directly from cod liver oil. Synthetic products are irritating to the human body and are only used as lubricants and UV protection agents. 3. Squalane is the most commonly used standard non-polar fixative, and its polarity is set to zero. The interaction between this type of stationary fluid and component molecules is dispersion force, and it is mainly used to separate general hydrocarbons and non-polar compounds.
