Raphanus Sativus Seed Oil

Raphanus Sativus (radish) seed oil is a lipid emollient used typically at a few percent up to full-oil phases in moisturizers, and as a class, cosmetic plant seed oils have low irritancy in standard patch testing when properly refined. The primary risk is idiosyncratic allergy or irritation in highly reactive eczema patients (less common than with fragranced/essential oils), so I score it as very gentle but not fully inert. Safety Notes: In commercial skincare and haircare, Raphanus Sativus (Radish) Seed Oil is commonly used as a lightweight emollient/slip agent and can appear at low levels (~0.1–1%) in lotions, creams, and cleansers where it functions as part of the oil phase. It is also sold directly to consumers as a single-ingredient facial/body oil or as a primary carrier oil in blends, where it can reach 50–100% in leave-on products. There are no specific EU/FDA maximum concentration limits for this cosmetic ingredient; practical upper use is governed by sensory profile, oxidation management, and formula type (leave-on vs rinse-off).
