About

A dimerized ester emollient created by capping dimer dilinoleyl dilinoleate with isostearyl alcohol — a very hydrophobic, high-molecular-weight emollient that provides a rich, cushioned skin feel.

Bis-Isostearyl Dimer Dilinoleyl Dimer Dilinoleate is a complex multi-dimer ester. The base molecule (dimer dilinoleyl dilinoleate) is formed from the oligomerization/polymerization of linoleic acid into dimer structures, then esterified with the same acid — creating a highly dimerized, branched molecule. The bis-isostearyl capping adds two isostearyl terminal groups, further increasing the lipophilicity and molecular weight. This type of ultra-hydrophobic emollient is prized in heavy moisturizers, body butters, and lip products for its rich, non-tacky feel and excellent occlusion properties. It is chemically inert and not restricted in cosmetics.

Skin benefits

  • Rich, luxurious emollient for dry skin formulations
  • Excellent occlusive — reduces transepidermal water loss
  • Improves product substantivity on skin

Known concerns

  • Very high molecular weight — no skin penetration concerns
  • May contribute to clogged pores and comedogenicity in acne-prone skin due to extreme occlusivity
