About P-ISOPROPYLPHENOL
A phenolic compound that causes severe skin burns and eye damage — a significant irritant that's harmful through multiple exposure routes. Not commonly used in cosmetics for good reason.
Detailed Analysis
p-Isopropylphenol (4-isopropylphenol, CAS 99-89-8, CID 7465) is an alkylphenol with multiple serious GHS hazard classifications: H302 (harmful if swallowed), H312 (harmful in contact with skin), H314 (causes severe skin burns and eye damage), and H332 (harmful if inhaled). Signal word is 'Danger.' As a substituted phenol, it has corrosive properties that damage the stratum corneum. While listed in CosIng as a perfuming agent, the severe hazard profile makes it unsuitable for most cosmetic applications without extreme dilution.
