Expert Verdict
Tree nut-derived; potential allergen concern for nut-allergic consumers; otherwise well-tolerated; related salts (e.g., SODIUM MACADAMIASEEDATE) are used as surfactants. Characterized by a fatty acid profile rich in oleic acid (~60%), palmitoleic acid (~20%), and palmitic acid; the high palmitoleic acid content is distinctive and mimics human sebum composition
