About MACADAMIA TERNIFOLIA SEED OIL PEG-8 ESTERS

An emollient ester derived from macadamia seed oil transesterified with PEG-8, delivering skin-conditioning benefits from a rich oleic/palmitoleic acid base.

Detailed Analysis

Macadamia Ternifolia Seed Oil PEG-8 Esters are obtained by transesterification of macadamia seed oil with PEG-8. Macadamia oil is rich in palmitoleic acid (omega-7, up to 23%), which is a natural component of human sebum and decreases with aging. The ethoxylation with PEG-8 improves water dispersibility while maintaining the emollient properties. As with other PEG-derivatized plant oils, residual ethylene oxide and 1,4-dioxane are the primary regulatory concerns under EU cosmetics rules.
