A skin cream has a formulation containing oil, water, and soy lecithin. The cream cannot achieve the desired consistency without soy lecithin. Why is soy lecithin important in this formulation?

Soy lecithin acts as a colorant, giving the cream its appearance.

Soy lecithin serves as an emulsifier, ensuring the cream's consistency.

Soy lecithin functions as a fragrance, enhancing the cream's scent.

Soy lecithin works as a coolant, reducing skin irritation.
