Toxcitv Both MIPB and DIPB are of a low order of toxicity and, therefore, require no special handling. Available toxicity data may be summarized as follows:
Oral Toxicity (rats) The Oral Lethal Dose in rats of 3. 38 grams per kilogram classifies the material as "slightly toxic" from the standpoint of ingestion of single oral doses. Skin Absorption (rabbits) The material is not readily absorbed through the unbroken skin. Skin and Eve Irritation (rabbital The sample produced no measurable irritation when applied to the skin for a period of 24 hours, nor did it cause any damage to eye tissues when instilled in the conjunctival sac. Vapor Inhalation (ratal Exposure to a high concentration of vapors for six hours failed to kill the rats.
Suggested Uses Chemical Intermediate; Heat Exchanger Fluid where a pure hydrocarbon with excellent radiation resistance, thermal stability, and/or electric characteristics are required; Plasticizer and High Temperature Dielectric.
