Functions

Film Forming

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

Hair Conditioning

A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.

Plasticiser

Emollient

Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.

Solvent

Dissolves other ingredients so they distribute evenly in the formula. Often the invisible "base" everything else is mixed into.

Locks In Moisture

Traditional Use

Synthetic ester developed for cosmetic and polymer applications in the mid-20th century. Used as a plasticizer and conditioning agent to improve product feel and spreadability.
