About MACADAMIA SEED OIL POLYGLYCERYL-4 ESTERS

A transesterification product of macadamia nut oil with polyglycerin-4, functioning as a gentle skin-conditioning emollient and emulsifier. The esterification process reduces the allergenic potential of whole macadamia protein, making it suitable for sensitive skin.

Detailed Analysis

Macadamia Seed Oil Polyglyceryl-4 Esters is produced by transesterifying Macadamia ternifolia (integrifolia) seed oil with polyglycerin-4, yielding a hydrophilic ester suitable for O/W emulsions and surfactant systems. The starting macadamia oil is rich in oleic acid (C18:1) and palmitoleic acid (C16:1), both beneficial for skin barrier function. Crucially, the esterification process removes macadamia protein allergens, substantially reducing sensitization risk compared to whole nut material. No EU restrictions apply under Regulation 1223/2009, and it is considered a safe, mild ingredient appropriate for sensitive-skin formulations.
