Lecithin is widely used as an emulsifier in the food industry, helping to mix 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, lecithin enhances dough elasticity and extends shelf life.

In the pharmaceutical and cosmetic industries, lecithin acts as a moisturizer and emulsifier in lotions, creams, and lip balms, improving skin hydration and product consistency. It is also used in dietary supplements to support brain health and liver function due to its high choline content.

In industrial applications, lecithin serves as a release agent in non-stick cooking sprays and as a dispersing agent in paints and coatings. Its versatility and natural origin make it a valuable ingredient across various sectors.
