  • Applications

    Didecyl sebacate is the diester of sebacic acid with decyl alcohol, commonly used as a plasticizer for PVC and other polymers to improve flexibility and processing. It also serves as an emollient and solvent in cosmetics and personal care products, contributing a smooth skin feel. In perfumery and fragrance formulations it can act as a solvent and carrier for fragrance oils and aroma compounds. It is used as a plasticizer and processing aid in coatings, inks, and adhesives, helping film formation and the final film properties. Additionally, it may function as a processing aid in polymer blends and as an ingredient in household product formulations where a relatively high‑molecular‑weight, low‑volatility diester is desired, subject to local regulations and formulation limits.
