Lecithin is widely used as an emulsifier in the food industry, helping to blend ingredients like oil and water that would otherwise separate. It is commonly found in products such as chocolate, margarine, and salad dressings to improve texture and stability. In baking, it enhances dough elasticity and extends shelf life.

In the pharmaceutical and cosmetic industries, lecithin acts as a moisturizer and emulsifier in creams, lotions, and ointments, improving skin hydration and product consistency. It is also used in dietary supplements for its potential to support brain health, liver function, and cholesterol management.

Additionally, lecithin is utilized in industrial applications, such as a release agent in non-stick cooking sprays and as a dispersing agent in paints and coatings. Its versatile properties make it a valuable ingredient across various sectors.
