Oryza Sativa Bran Cera

Oryza Sativa (Rice) Bran Cera is a wax used mainly as an emollient/thickener and film-former, typically at low percentages in creams and balms. Waxes of this type are generally well-tolerated with low rates of irritant reactions in patch testing, though very reactive or eczema-prone skin can occasionally experience intolerance from occlusion or contact sensitivity to minor impurities. Given its non-active role and low inherent reactivity but acknowledging rare sensitivity in compromised skin, it fits a very gentle score. Safety Notes: Oryza Sativa Bran Cera (rice bran wax) appears at low concentrations (0.1-0.5%) in lightweight lotions and serums as a minor texture modifier and emollient. At the high end, specialized lip balms, solid balms, and anhydrous stick formulations utilize concentrations up to 10-15% where it functions as a primary structuring agent and occlusive barrier. Leave-on products across the full range are common, with higher concentrations typically found in targeted treatment balms and waterless formulations where its waxy texture and film-forming properties are desirable.
