About this ingredient

SD Alcohol 39-C is ethyl alcohol denatured under formula 39-C (additives that make it undrinkable). INCI: Alcohol Denat. / SD Alcohol 39-C. In a formula it works as a solvent and fast-evaporating carrier: it dissolves oils and actives, speeds drying, gives a light matte feel, and supports antisepsis. It is used in toners, sprays, fragranced and sun-care products that need a non-greasy, quick-drying base. Concentration sets the character: small amounts make a neutral processing solvent, high amounts an active degreaser. Tolerance. High alcohol levels dry the skin, raise transepidermal water loss, and irritate dry, sensitive, and rosacea-prone skin. If alcohol sits near the top of the list the product is likely drying; near the end it is a low-dose solvent. Pregnancy safety. At cosmetic concentrations topical use is systemically negligible. The component has no skincare effects of its own.
