A clear, light, dry-touch oil used in moisturisers, makeup and sunscreens as a silicone alternative. Generally well tolerated, with sustainability and minor environmental persistence as the main flags.

Skin benefits

  • Stable to oxidation, with a long shelf life
  • Listed on EU CosIng as an acceptable cosmetic ingredient

Known concerns

  • Petroleum-derived feedstock raises sustainability questions

  • Possible mild skin irritation in occlusive applications on damaged skin
  • Quality grade and purity depend on supplier hydrogenation
