Safety

CIR Status
Not reviewed
Sensitization risk High

Ethyl Methylbutyl Ketoxime is associated with a risk of slight skin irritation and severe eye irritation, potentially causing serious eye damage. It can be absorbed through the skin, leading to possible harmful effects on the blood and nervous system. Limited evidence suggests a potential carcinogenic effect, and it may interfere with alcohol metabolism, resulting in adverse reactions like acetaldehyde formation, facial flushing, red eyes, and fatigue. Its primary safety assessments and applications are predominantly industrial, not cosmetic.
