t-Butyl Alcohol is generally suitable within the cosmetic uses reviewed. The newer assessment retains that conclusion for the described exposures, while identifying an evidence gap for airbrush application.

The final amended report also corrects an older patch-test concentration and updates the exposure assessment. High-dose oral animal findings and undiluted eye exposure should keep their route and concentration limits. No independent human seb derm or applicable Malassezia benefit was established. Consider the product’s intended format and seek advice about irritation or uncertain suitability.
