About

A long-chain hydrocarbon emollient that gives a silky, silicone-like slip. Inert and well tolerated topically; quality grading matters because the source can be petroleum or plant.

  • Silicone-style slip without silicones
  • Inert and well tolerated
  • Often plant-derived (synthesized) grade

Known concerns

  • Variable purity by source
  • Petroleum-derived grades flagged for impurity controls
  • Not biodegradable (typical mineral hydrocarbon)
