Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
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
Triglycerides from plant and animal sources have been used for thousands of years in traditional skincare oils and salves. The C10-18 form is a modern fractionated derivative developed for enhanced absorption and sensory properties in cosmetics.
