Pentaclethra Macroloba Seed Oil

Pentaclethra macroloba seed oil (pracaxi oil) is primarily an emollient/occlusive lipid used in leave-on products (often a few percent up to higher levels in oils/balms) and is generally well-tolerated, similar to other non-volatile plant oils. However, as a natural botanical oil it contains minor constituents that can trigger irritation or allergy in a subset of highly reactive or eczema-prone patients, and oxidized oil can further increase sting/erythema risk. Given these real-world sensitization/irritant possibilities despite an overall soothing profile, it fits best as a “gentle” ingredient rather than very gentle or inert. Safety Notes: In mass-market creams/lotions and multi-oil blends, Pentaclethra macroloba (pracaxi) seed oil is often used as a minor emollient or marketing-active at ~0.05–1%, with many leave-on body lotions and hair products clustering around ~0.5–5% as part of the oil phase. Higher-strength consumer products include facial/body oils, balms, and anhydrous hair/scalp oils where pracaxi is a primary lipid typically ~10–50%, and it is also sold directly as single-ingredient “100% pracaxi oil” for leave-on use, setting the practical OTC maximum at 100% (rinse-off formats rarely go as high due to cost and wash-off, but can still include low single-digit percentages).
