Functions
Solvent
Dissolves other ingredients so they distribute evenly in the formula. Often the invisible "base" everything else is mixed into.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Humectant Carrier
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
Provides scent
Dissolves other ingredients
Traditional Use
A synthetic ester solvent developed for industrial and cosmetic applications in the 20th century. It was designed to improve formula stability and product texture in makeup and skincare products.
