Chlorella vulgaris, like other microalgae, contains a range of fatty acids, including oleic acid. Oleic acid is abundant in various food sources, especially plant-based oils. Olive oil is particularly known for its high oleic acid content. Other sources include canola oil, avocado oil, almond oil, and peanut oil. Animal fats, such as lard and tallow, also contain oleic acid.

Health Benefits: Oleic acid has been associated with several health benefits. It is known to have a positive impact on heart health by helping to lower LDL cholesterol levels while maintaining or increasing HDL cholesterol levels. It also has anti-inflammatory properties and may contribute to improved insulin sensitivity.

Surfactants and Emulsifiers: Oleic acid is widely used in the production of surfactants and emulsifiers. Surfactants are compounds that lower the surface tension between liquids or between a liquid and a solid, enabling them to mix more easily. Emulsifiers help stabilize and blend immiscible substances, such as oil and water, by reducing interfacial tension. Oleic acid’s amphiphilic nature, meaning it has both hydrophilic and hydrophobic properties, makes it an effective ingredient in these formulations.

Soaps and Detergents: Oleic acid is a key component in the production of soaps and detergents. It functions as a surfactant, allowing the removal of dirt and oils from surfaces. In soap production, oleic acid is often used in combination with other fatty acids to achieve the desired cleansing and moisturizing properties.

Lubricants and Greases: Oleic acid is utilized in the manufacturing of lubricants and greases. It can be used as a base oil or as an additive to improve the lubricating properties of the final product. Oleic acid’s low volatility, high oxidative stability, and excellent lubricity make it suitable for a wide range of applications, including automotive lubricants, metalworking fluids, and industrial greases.

Cosmetics and Personal Care Products: Oleic acid is commonly employed in the formulation of cosmetics and personal care products. It acts as an emollient, providing moisturization and enhancing the texture and feel of skincare creams, lotions, and hair care products. Oleic acid’s skin compatibility and softening properties make it beneficial for various cosmetic applications.

Pharmaceuticals: Oleic acid finds application in the pharmaceutical industry as an excipient, which is an inactive ingredient in medications. It is used as a binder, lubricant, and solubilizing agent in tablet formulations. Additionally, oleic acid can be encapsulated or complexed with drugs to enhance their delivery and bioavailability.
