Brassica Alcohol (Brassica Oil Derived) and Cetyl Alcohol (Vegetable Derived) are fatty alcohols found in plant cells that do not behave like other alcohols, such as ethanol or propanol. These alcohols are not drying; they condition & soften the hair and increases manageability. Alcohol Denat. (grain derived) is a natural alcohol that is used in our Blossom & Bloom Ginseng + Biotin Volumizing Spray to absorb excess oil in the hair to give the roots lift and volume. Benzyl Alcohol is an ECOCERT preservative used to maintain the shelf life and integrity of our products.
