  • Applications

    Carnosic acid (CAS 3650-09-7) is a natural phenolic compound primarily sourced from rosemary, used as an antioxidant and stabilizer in multiple product formulations. In cosmetics and personal care, it acts as an antioxidant and stabilizer to protect oxidizable ingredients and extend product shelf life. In food processing, it is evaluated as a natural antioxidant to slow lipid oxidation and preserve fats and processed foods. In the plastics and coatings industry, it is studied as a natural antioxidant/stabilizer for polymers and coatings to reduce oxidative degradation. It is also considered for potential applications in inks and adhesives as a stabilizing antioxidant additive, subject to regulatory and formulation constraints.
