Squalene vs. Squalane: Understanding the Difference and Benefits

When it comes to skincare ingredients, the devil is often in the details. Two compounds that frequently cause confusion due to their similar names and related properties are squalene and squalane. While they may sound interchangeable, these two molecules have distinct differences that can significantly impact their function and benefits in skincare and other applications. This article will delve into the science behind squalene and squalane, their sources, uses, and why one might be preferred over the other in certain contexts.

What is Squalene?

Squalene is a naturally occurring compound that is a triterpene, which is a type of hydrocarbon. It is produced by all plants and animals, including humans, as a precursor to cholesterol and other steroids. In humans, squalene is found in sebum, the oily substance produced by our skin glands, which helps to keep our skin moisturized and protected.

• Squalene is an unsaturated oil, meaning it has double bonds in its molecular structure.
• It is highly susceptible to oxidation when exposed to air and light, which can lead to the breakdown of the compound and the formation of potentially harmful by-products.
• Squalene is harvested from a variety of sources, including shark liver oil, olives, amaranth seed, rice bran, and wheat germ.

What is Squalane?

Squalane is a saturated hydrocarbon derived from squalene. Through a hydrogenation process, the double bonds in squalene are converted into single bonds, creating a stable and fully saturated compound. This saturation gives squalane a much longer shelf-life and makes it less prone to oxidation.

• Squalane is a stable, non-oxidizing oil that is commonly used in cosmetics and skincare products.
• It is a lightweight, non-greasy emollient that is easily absorbed by the skin.
• Like squalene, squalane can be derived from both animal and plant sources, but ethical and sustainable practices typically favor plant-derived squalane.

Comparing Squalene and Squalane

While squalene and squalane have similar origins and can be derived from the same sources, their differences in stability and skin compatibility make them suitable for different applications.

Stability and Oxidation

The unsaturated nature of squalene makes it highly reactive with oxygen, leading to oxidation and potential skin irritation or allergic reactions. Squalane, on the other hand, is resistant to oxidation, making it a more stable ingredient in formulations that are exposed to air and light.

Moisturizing Properties

Both squalene and squalane are excellent moisturizers. However, squalane’s stability and lighter texture make it a preferred choice for skincare formulations, as it provides long-lasting hydration without leaving a greasy residue.

Sources and Sustainability

The traditional source of squalene has been shark liver oil, which has raised concerns about the impact on shark populations and the ecosystem. As a result, there has been a shift towards using plant-based sources for both squalene and squalane. Plant-derived squalane is considered a more sustainable and ethical option.

Uses of Squalene and Squalane in Skincare

Both compounds are valued in skincare for their emollient properties, but squalane’s stability makes it the preferred choice for formulators.

• Squalene: Due to its oxidative nature, squalene is less commonly found in skincare products. It may still be used in small quantities in certain formulations where its benefits outweigh the risks of oxidation.
• Squalane: Squalane is widely used in a variety of skincare products, including moisturizers, serums, facial oils, and lip balms. Its compatibility with all skin types and non-comedogenic properties make it a versatile ingredient.

Environmental and Ethical Considerations

The shift towards plant-based squalane reflects a broader trend in the cosmetics industry towards sustainability and ethical sourcing. Consumers are increasingly aware of the environmental impact of their purchases, leading to a demand for products that do not contribute to the depletion of wildlife or natural resources.

Conclusion: The Superiority of Squalane

In conclusion, while squalene and squalane share a common origin and similar moisturizing properties, squalane’s stability, non-greasy feel, and suitability for all skin types make it the superior choice for skincare formulations. Its resistance to oxidation ensures that products remain effective and safe over time, while plant-derived squalane aligns with ethical and environmental values.
