Squalene: What is Squalene?

Definition and Properties of Squalene

Squalene is a naturally occurring organic compound that belongs to the family of hydrocarbons known as terpenes. It is commonly found in plants, animals, and even humans. Chemically, squalene is classified as a polyunsaturated hydrocarbon because it contains six double bonds. This unique chemical structure gives squalene its liquid form at room temperature. It is odorless, colorless, and highly stable, making it an ideal ingredient for various applications in the nutrition and supplements industry.

Squalene is primarily found in shark liver oil, though it can also be sourced from plants, such as olives and wheat germ. Its extraction process entails several steps, including centrifugation, filtration, and purification. Once obtained, squalene undergoes further refinement to remove impurities and improve its quality. The final product is a highly pure and concentrated form of squalene, which can be used in different dietary supplements, skincare products, and pharmaceutical applications.

Extraction and Production Methods of Squalene

The extraction of squalene from shark liver oil involves a meticulous process. After the liver is harvested, it is carefully cleaned and sliced to expose the squalene-rich oil. The oil is then separated from the rest of the liver tissue through centrifugation, which uses rotational force to separate the different components based on their densities. The resulting oil is subjected to filtration to remove any remaining impurities. Finally, the squalene is purified through a series of distillation and molecular separation techniques to obtain a highly concentrated form.

In recent years, due to environmental concerns and the desire to preserve shark populations, alternative sources of squalene have gained popularity. One such source is plant-derived squalene. Extraction methods for plant-based squalene vary depending on the source, but they generally involve mechanical pressing or solvent extraction. Olives, for example, are mechanically pressed to release the squalene-rich oil, which is then further refined. Wheat germ, on the other hand, undergoes solvent extraction using food-grade solvents to extract the squalene. These plant-based extraction methods offer a sustainable and cruelty-free alternative to shark-derived squalene.

Applications and Benefits of Squalene

Squalene has gained recognition for its numerous applications and benefits in the nutrition and supplements industry. One of its primary uses is as a dietary supplement. Squalene is believed to possess antioxidant properties, which help protect the body against harmful free radicals. Additionally, it is thought to improve overall cardiovascular health by maintaining healthy cholesterol levels. Some studies suggest that squalene may also have anti-inflammatory properties, making it potentially beneficial in managing certain inflammatory conditions.

In the skincare industry, squalene is highly regarded for its moisturizing properties. It is easily absorbed by the skin, helping to prevent moisture loss and maintain skin hydration. Squalene is also believed to have anti-aging effects, as it may help reduce the appearance of wrinkles and fine lines. Furthermore, its antioxidant properties contribute to protecting the skin from environmental damage.

In conclusion, squalene is a versatile compound with various applications and benefits. Whether sourced from shark liver oil or plants, squalene offers antioxidant, anti-inflammatory, and moisturizing properties, making it a valuable ingredient in the nutrition and supplements industry. As the demand for sustainable alternatives grows, plant-derived squalene provides an ethical option without compromising its quality and effectiveness.
