WHAT'S IT DO?
Functions
Fragrance
Added for scent. Can be natural or synthetic. Common irritant and allergen — one of the top reasons people react to products.
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.
Skin Conditioning Emollient
Smooths and softens skin
Dissolves other ingredients
