Prunus Amygdalus Dulcis Oil

Prunus Amygdalus Dulcis (sweet almond) oil is primarily an emollient used at high concentrations (often 5–100%) and is generally well-tolerated, but it is not inert. Clinical experience and patch testing show a low-to-moderate risk of irritation or allergic contact dermatitis in reactive individuals, particularly those with eczema or nut-protein sensitivity due to potential trace protein contaminants. Given frequent use in leave-on products and the high-stakes population of compromised skin, a mild irritancy score is warranted. Safety Notes: In mass-market leave-on creams/lotions/serums, Prunus Amygdalus Dulcis (Sweet Almond) Oil is often used at very low levels (~0.05–0.5%) as an emollient/skin-feel modifier within larger oil phases, with many formulas clustering around 1–10%. At the high end, it is widely sold to consumers as a single-ingredient “sweet almond oil” body/hair oil, where it can be 100%, and it is also commonly the dominant carrier oil in anhydrous balms and cleansing oils (often 30–90%+). No specific EU/FDA concentration cap applies for this cosmetic ingredient; practical limits are driven by product format (rinse-off vs leave-on) and desired texture/occlusivity.
