Functions
Emulsion Stabilising
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Solvent
Dissolves other ingredients so they distribute evenly in the formula. Often the invisible "base" everything else is mixed into.
Moisturizing
Locks in moisture to keep skin soft and supple throughout the day
Antimicrobial
Strengthens Barrier
Keeps product blended
Traditional Use
A synthetic emollient and solubilizer developed for modern cosmetics with no traditional predecessor. Created to provide light texture and improved product stability in contemporary skincare formulations.
