How does lecithin emulsify coconut oil?

Lecithin acts as an emulsifier by reducing the surface tension between water and oil, allowing them to mix more effectively. In the case of coconut oil, lecithin's phospholipid molecules have hydrophilic (water-attracting) and hydrophobic (water-repelling) properties, enabling it to interact with both the oil and any aqueous phase. This interaction stabilizes the emulsion, preventing the separation of the oil and water components. As a result, lecithin helps create a smooth, uniform mixture of coconut oil with other ingredients.
