Cetane Improvers
Cetane improvers are diesel fuel additives that raise the cetane number to improve ignition quality, cold starting, combustion smoothness and emissions in compression-ignition engines. The dominant chemistry is 2-ethylhexyl nitrate (2-EHN), with di-tert-butyl peroxide used in some formulations. For EU and GCC buyers, these are bought as additive-grade products defined by active-ingredient content and cetane-boosting response.
Grades are defined by chemistry and purity. 2-EHN is specified by assay (commonly 95%+), nitrogen content, density and thermal stability; peroxide-based improvers are specified by active-oxygen content. Treat rates are typically expressed in parts per million or percentage by volume to achieve a target cetane gain, and the response varies with the base fuel. Key parameters include assay, density, nitrogen content and flash point. HS codes are provided on documentation; precise CAS framing is given per product on the SDS.
Cetane improvers ship in drums (200-210 L), IBCs and ISO tanks. 2-EHN and peroxide products carry flammability and, for peroxides, organic-peroxide hazard classifications, shipped under assigned UN numbers per ADR/IMDG with temperature-control requirements for some peroxides.
Compliance typically includes SDS provision, CLP/GHS labelling, REACH registration or Only Representative routing for EU entry, and SABER/SASO registration for Saudi Arabia, coordinated where required. Temperature-control and segregation requirements for peroxide grades are flagged at inquiry as documentation.
Himalay's verified manufacturer and exporter partners supply cetane improvers with CoA per batch, SDS, REACH/CLP compliance coordinated for EU, GHS labelling, and SABER for Saudi Arabia handled as part of the standard order flow.
