Linoleic acid is used in various industries, particularly in health and beauty. In the food industry, linoleic acid is a key component in vegetable oils such as sunflower oil and soybean oil, which supports heart and vascular health. It is also used as an ingredient in dietary supplements to help reduce cholesterol and balance body fats.

In beauty care, linoleic acid is a component in skin care products such as creams, serums, lotions, and moisturizers due to its properties that enhance moisture, strengthen the skin barrier, and reduce skin inflammation. It also stimulates collagen production, making the skin appear youthful and healthier.

Additionally, linoleic acid is used in the pharmaceutical industry to produce treatments for skin conditions such as acne, eczema, and psoriasis, owing to its anti-inflammatory properties and ability to repair skin.

Linoleic acid also serves as a precursor in the production of biofuels and biodegradable lubricants, supporting sustainable industrial applications. Furthermore, adding linoleic acid to animal feed enhances growth and improves the quality of meat and dairy products.
