Squalane CAS 111-01-3

Squalane is an important component of human sebum, and the sebum secreted by the sebaceous glands of human skin contains approximately 10% squalene and 2.4% squalene. The human body can convert squalene into squalane. Squalene can provide oxygen and nutrients to cells, promote cell metabolism, form a sebum membrane on the outer layer of the skin, prevent water loss, and isolate bacteria, dust, and UV damage. However, the secretion of squalene in women rapidly decreases from around the age of 25, leading to problems such as skin dehydration, sagging, dullness, and aging. So, supplementing the skin with squalane is quite important! 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 generally encapsulated in capsules and suitable for oral administration; And squalane is a stable state of pure oil, suitable for external use.
