Phenethyl acetate Safety Profile

Risk Statements: 36/37/38
R36/37/38:Irritating to eyes, respiratory system and skin.
Safety Statements: 24/25
S24/25:Avoid contact with skin and eyes.
WGK Germany: 1
RTECS: AJ2220000
HS Code: 29153990
Moderately toxic by ingestion. Mildly toxic by skin contact. A skin irritant. Combustible when exposed to heat or flame; can react vigorously with oxidizing materials. To fight fire, use alcohol foam, CO₂, and dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.
