Akzo Nobel Polymer Chemicals LLCMATERIAL SAFETY DATA SHEETCadox M-50The neurotoxic effects of this product are not known.Other toxicological informationOverexposure to this product may affect the skin, eyesand respiratory system.Exposure to DIMETHYL PHTHALATE has shown avery low order of toxicity in animals by the oral,inhalation or dermal routes. It is not irritating to theskin but is absorbed through the skin. Dimethylphthalate can cause respiratory irritation, eye pain andstomach irritation. Inhalation has been reported tocause cough, irritation and/or paralysis.While the toxicity of dimethyl phthalate has beenminimized by most reviewers, there have beenpoisonings from ingestion of a product where dimethylphthalate has been mixed with methyl ethyl ketoneperoxide. These cases have resulted in a burningsensation of the mouth, vomiting, diarrhea, and comafollowed by liver and kidney failure and pneumonitis. Itis probable that these effects were primarily from themethyl ethyl ketone peroxide and not the dimethylphthalate.12.
