About P-CRESYL ISOBUTYRATE
P-Cresyl Isobutyrate is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
Detailed Analysis
p-Cresyl isobutyrate is the esterification product of p-cresol with isobutyric acid, used as a fragrance compound with a sweet-floral odor profile. The EU's SCCS has assessed this cresyl derivative and identified skin sensitization as the primary toxicological concern, consistent with the broader class of cresol and phenolic fragrance materials. IFRA guidelines impose concentration restrictions, and the ingredient must be declared as a fragrance allergen under EU cosmetic labeling requirements. It is not banned in Annex II but requires careful formulation control.
