It is commonly found in products like 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 to support brain health and liver function.

Additionally, lecithin is utilized in industrial applications, such as a release agent in mold manufacturing and a dispersing agent in paints and coatings. Its versatility makes it a valuable ingredient across various sectors.
