  • Applications

    Rosacetol (CAS 90-17-5) is a chemical used across multiple industrial and consumer formulations. In the fragrance sector, it is typically employed as a fragrance ingredient and may function as a fixative to slow evaporation. In cosmetics and personal care, it can act as a solvent and scent component. In household cleaning products, it is used as a fragrance additive and solvent for formulation. In the polymers/plastics and coatings/inks sectors, it can act as a processing aid or intermediate and may be used as a solvent or additive in formulations. In adhesives, it may be used as a solvent or fragrance-like additive, subject to local regulations and formulation limits.
