Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate Prunus Amygdalus Dulcis (Sweet Almond) Oil
Appears to be a non-standard, concatenated ingredient entry combining the antioxidant pentaerythrityl tetra-di-t-butyl hydroxyhydrocinnamate with sweet almond oil. The antioxidant is used to protect formulas from oxidation and help improve product stability; CIR describes it as used in cosmetics as an antioxidant and safe in the present practices of use and concentration.

Risks & Warnings
Low expected skin risk at cosmetic use levels. Main concerns are potential sensitivity to sweet almond oil in people with tree-nut allergy, and the usual rare possibility of irritation from botanical oil-based ingredients. The antioxidant itself is assessed as safe in cosmetics by CIR. ([journals.sagepub.com](https://journals.sagepub.com/doi/10.1177/1091581818803326?utm_source=openai))
