Sources[edit | edit source]
Squalane is primarily derived from shark liver oil. However, due to environmental concerns, plant-derived squalane is becoming more common. Plant sources of squalane include olive oil, rice bran oil, wheat germ, and yeast.
Uses[edit | edit source]
Squalane is commonly used in cosmetics and skin care products. It is a powerful moisturizer and has emollient properties. It is also used in the production of vaccines as an adjuvant.
Benefits[edit | edit source]
Squalane has several benefits for the skin. It helps to moisturize the skin, reduce wrinkles, and improve skin elasticity. It also has anti-inflammatory properties and can help to soothe skin conditions such as eczema and dermatitis.
Safety[edit | edit source]
Squalane is considered safe for use in cosmetics and skin care products. It is non-toxic and non-irritating to the skin. However, it should be used with caution by individuals with oily skin or acne-prone skin, as it may clog pores and contribute to acne.
Environmental Impact[edit | edit source]
The extraction of squalane from shark liver oil has raised environmental concerns. Sharks are often killed solely for their liver oil, leading to a decline in shark populations. As a result, many companies are now using plant-derived squalane.
