About MACADAMIA TERNIFOLIA SEED OIL PHYTOSTEROL ESTERS

A premium skin conditioning agent combining macadamia nut oil with phytosterols, offering exceptional skin compatibility and barrier-supporting properties.

Detailed Analysis

Macadamia ternifolia (macadamia) seed oil is unique among plant oils for its high oleic acid content (~60%) and exceptionally high level of palmitoleic acid (~20%), a fatty acid also present in human sebum (∼10%). Phytosterols (primarily beta-sitosterol, campesterol, and stigmasterol) are steroid-derived compounds that integrate into the skin's lipid layers, helping to reinforce the stratum corneum barrier and reduce transepidermal water loss (TEWL). Esterification of macadamia oil with phytosterols creates a lipophilic ingredient with enhanced skin affinity and superior emollient performance. No EU Annex II or III restrictions apply.
