Persea Gratissima Oil

Persea Gratissima (avocado) oil is primarily an emollient/occlusive lipid used at low to high concentrations (often 1–100%) to support barrier function, and it is generally well tolerated in leave-on products. However, clinical experience and patch testing show that a minority of sensitive or eczema-prone patients can experience irritation or allergic contact dermatitis to avocado-derived components (including protein residues), so it cannot be considered "very gentle" for all compromised skin. Given the low overall irritancy rate but non-zero sensitization risk, a gentle score is the safest fit. Safety Notes: In commercial skincare, Persea Gratissima (Avocado) Oil is frequently used at very low levels (~0.05–0.5%) as an emollient/label claim component in lotions, cleansers, and serums (both leave-on and rinse-off). Mid-range use (1–20%) is common in creams, balms, cleansing oils, and hair/scalp treatments where it functions as a primary emollient and lipid phase contributor. The upper end includes single-ingredient avocado oil products marketed for face/body/hair and multipurpose oils, which are effectively 100% (or ~99–100%) avocado oil and are broadly available OTC; there is no specific FDA/EU maximum concentration limit for the oil itself beyond general cosmetic safety requirements.
