  • Applications

    2-Methylheptacosane (CAS 69198-91-0) is a long-chain, branched hydrocarbon that is commonly used as a base oil and wax-like component in formulations. Practical applications span: (1) cosmetics and personal care, as a hydrocarbon emollient and wax-thickening agent in creams and balms; (2) lubricants and greases, as basestock or additive to improve lubricity and high-temperature stability; (3) coatings and inks, as a wax additive to enhance slip, water resistance, and gloss of coatings or printed layers; (4) polymers and plastics, as a processing aid or surface-slip additive during compounding and shaping; (5) industrial cleaning and degreasing, as a non-polar constituent in solvent systems. Its use is subject to local regulations and formulation limits.
