Functions
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks In Moisture
Traditional Use
Lanolin from sheep's wool has been used for centuries as a moisturizer and skin protectant. The PEG-75 version was developed in the 20th century to create a more water-soluble form suitable for modern cosmetic formulations.
