Glycerin is a by-product of soap manufacturing and is a clear, syrupy liquid, usually derived from vegetable oil and obtained by adding alkalies to fats and fixed oils. It is a solvent humectant and emollient in many skin care products, as it absorbs moisture from the air and thereby helps products retain their moisture. It improves the spreadability of products and has definite skin moisturizing benefits.
