M-TERT-BUTYLPHENYL ISOBUTYRALDEHYDE.

Questionable CAS 62518-65-4 / PERFUMING

M-TERT-BUTYLPHENYL ISOBUTYRALDEHYDE is a synthetic compound predominantly valued for its fragrant attributes in cosmetic formulations and perfumery. Although its use is permitted under specific regulatory restrictions, it has been identified as a critical dermal sensitizer. Due to its potential to elicit allergic reactions in susceptible individuals, its inclusion in precision skincare requires careful consideration.

While no direct CIR or FDA status was found, the International Fragrance Association (IFRA) has imposed strict usage restrictions due to critical effects including dermal sensitization and potential systemic toxicity. For instance, its maximum allowed concentration in face moisturizer products (Category 5B) is 0.28%, but this limit varies significantly depending on the specific product category. The identified dermal sensitization risk suggests a potential for allergic reactions.
