If the word squalene [or squalane] seems familiar to you, it probably is. Squalene is a very common emollient used in beauty products such as lotions, creams and glosses and is used by big name companies such as L’Oréal Paris. However, squalene is being phased out of cosmetic products as of late due to the vast decline in numbers of deep-sea sharks.

Squalene, which has been an in demand ingredient for beauty products is found in large quantities in the livers of deep-sea sharks and due to the sharks being caught and killed purely for this ingredient, cosmetic companies are seeking the aid of olive extracts to replace the deep-sea shark liver oil. However, if all companies switch to olive extracts, simple supply and demand may be in trouble, as there are only so many olives to go around to big companies.

In 2006, L’Oréal eliminated squalene from their skin care products replacing it with a plant-based substitute and plan to eliminate the ingredient from 12 other lipsticks that they produce. Asian-based cosmetic companies may not be going the same route, though, as shark squalene still remains in very high demand.

So the next time you’re picking up your favorite skin care item, lipstick or gloss and you see squalene listed in the ingredients you can now say you not only know what it means, but know that the company has decided to continue to use deep-sea shark oil in their product and have not opted for either olive extracts or plant-based substitutes. Help eliminate the cause for concern over the dwindling numbers of deep-sea sharks.
