Kukui Oil

aka aleurites moluccana seed oil · candlenut oil · kukui nut oil

Hawaiian-origin botanical oil used in highlighting and illuminating colour formulas for its lightweight emolliency and skin-identical fatty acid profile. High linoleic and alpha-linolenic acid content.

Benefits
  • Lightweight emollient
  • High linoleic acid (up to 42%) — supports barrier-compatible fatty acid delivery
  • Alpha-linolenic acid anti-inflammatory activity
  • Absorbs quickly — non-greasy
  • High unsaturated fatty acid content
Example uses
  • Highlighting blush formulas
  • Face oils
  • Skin care serums
  • After-sun oils
  • Illuminating primers
Formulation notes

Highly unsaturated — oxidation-prone. Requires antioxidant protection (vitamin E) and UV-protective packaging. Short shelf life without stabilisation.

Watchouts

High polyunsaturated fatty acid content makes it susceptible to oxidative rancidity. Not suitable for high-temperature processing. Shelf life stability requires careful management.

Clean beauty perception

Accepted in clean beauty. Hawaiian provenance narrative. Sustainable sourcing of candlenut should be verified.
