Functions

Humectant

A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.

Plasticiser

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.

Occlusive

Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.

Locks In Moisture

Traditional Use

A hybrid synthetic ingredient combining PEG with silicone (dimethicone), developed in the late 20th century. Silicones were first used in cosmetics in the 1950s; this PEG modification improved water solubility for modern formulations.
