Health Factors
International Agency for Research on Cancer (IARC) carcinogenic classification: Group 3, not classifiable as to its carcinogenicity to humans
Potential symptoms: Eye, nose, respiratory, skin irritation; INGES ACUTE: Nausea, vomiting, abdominal cramps, diarrhea.
Health Effects: Irritation-Eyes, nose, skin---Mild (HE16).
Affected organs: Eyes, skin, GI tract
Notes: 1) OSHA does not have a PEL for piperonyl butoxide. 2) Piperonyl butoxide is usually mixed with pyrethrins and related insecticides to inhibit their metabolism by cytochrome P-450 mixed-function oxidases, and thus could inhibit the metabolism of many drugs. 3) It is highly toxic to fish and aquatic organisms and bioaccumulates in them, including those consumed as seafood. 4) The half-life for urinary excretion of radioactivity from [14C]-piperonyl butoxide in a commercial head lice treatment formulation applied for 30 minutes on human forearm skin is 32 hours.
