Arachis Hypogaea Oil

Arachis Hypogaea (peanut) oil is primarily an emollient used at relatively high concentrations in creams and ointments, and while it is often well-tolerated, it is not reliably “non-irritating” in sensitive populations. Patch-test and clinical experience show low-to-moderate rates of irritation/sensitization concerns, with particular safety relevance in atopic dermatitis where reactivity and allergy risk are higher. Given its frequent leave-on use and the potential for clinically meaningful reactions in eczema-prone patients, a mild irritancy score is warranted. Safety Notes: In commercial skincare, Arachis Hypogaea (Peanut) Oil is often used at very low levels (~0.05–1%) as an emollient/lipid component within creams, lotions, cleansers, and balms where it functions as part of the oil phase. Mid-range usage (~2–20%) is common in richer body creams, massage products, and cleansing oils, while the highest strengths occur in consumer-available body oils and carrier-oil products marketed as pure peanut oil, which can be 100% (leave-on); rinse-off soaps/body washes may also include it but typically at lower percentages due to surfactant systems. There is no specific EU/FDA cosmetic concentration cap for peanut oil itself, but allergen sensitization risk drives labeling/market choices and tends to limit use in many facial products.
