Uses and applications

What the substance is used for, by industry and function

Monomer for polyalpha-olefin synthetic lubricants, in linear alpha-olefin mixt for prodn of primary alcohols, chemical intermediate for oxo-process n-undecyl alcohol.

Organic synthesis of flavors, perfumes, pharmaceuticals, dyes, oils, resins.

Industrial uses: Viscosity modifiers, Intermediate, Lubricating agent.

Consumer uses: Intermediate, Viscosity modifiers.

Cosmetic ingredient, INCI name DECENE(solvent, viscosity controlling)

Roles

  • metabolite

Functional uses

  • Deodorizer
  • Fragrance
  • Softener and conditioner
  • Solvent

Cosmetic functions

  • Fragrance
  • Hair conditioning
  • Perfuming
  • Skin conditioning
  • Skin conditioning - emollient
  • Solvent
  • Viscosity controlling

How it is made

Oligomerization of ethylene using triethylaluminum catalyst and fractional distillation of the resulting alpha-olefin mixture

High purity ethylene contacts a nickel catalyst in a butanediol reaction medium. The alpha-olefins produced separate from the solvent because they are insoluble in the polar medium.
