What's squalene?


Squalene (2,6,10,15,19,23-hexamethyl-2,6,10,14,18,22-tetracosahexaene), is a lipid found in large quantities in shark liver oil and in smaller amounts (0.1 to 0.7 %) in olive oil, wheat germ oil, rice bran oil and yeast.
It is a key intermediate in the biosynthesis of cholesterol.
Having 6 double bonds, Squalene is very unstable versus oxidation and this is why it's often hydrogenated.
Once Hydrogenated, Squalane, is a stable emollient for cosmetics.
