Functions
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
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, the traditional emollient from sheep's wool used for centuries in creams and ointments, combined with PEG polymers in the 20th century. Developed to improve the spreadability and water-solubility of this natural wax.
