Helianthus Annuus Seed Cera

Helianthus Annuus (sunflower) Seed Cera is a plant-derived wax used primarily as an emollient/structuring agent in balms, sticks, and creams, typically at low-to-moderate concentrations to increase viscosity and occlusivity. As an inert lipid-wax mixture it has a low rate of irritation in patch testing and clinical use, but it is not completely risk-free in highly reactive or eczematous skin (rare intolerance/contaminant-related reactions), so it scores as very gentle rather than inert. Safety Notes: Helianthus Annuus Seed Cera (sunflower seed wax) is used at very low levels (~0.05–0.5%) as a viscosity/structure aid in emulsions and leave-on lotions/creams, and around 0.5–5% in stick products, balms, and butters to build body and improve payoff. In high-structure anhydrous consumer products (lip balms, deodorant sticks, solid balms, and some waterless salves), it can be pushed into the ~10–20% range as a primary structuring wax; higher levels are generally limited by hardness, drag, and crystallization/texture control rather than regulation (no specific EU/FDA maximum for this cosmetic wax).
