j MSM Document Vicwel� age 0f 8 HAZARDOUS POLYMERIZATION: Will not occur. 11.0 TOXICOLOGICAL INFORMATION ACUTE TOXICITY DATA: EYE IRRITATION: Primary eye irritation score for similar materials have ranged from 0.0 to 3.31110(rabbits). SKIN IRRITATION: Similar products have produced skin irritation scores ranging from 1.96 to 63018.0 (rabbits). Dermal LD50 for similar products was greater than 2 g/kg (rabbits). DERMAL LD50; Testing not conducted. See Other Toxicity Data. ORAL LD50: Ozal LD50 for similar products was greater than 10 g/kg(rats). INHALATION LC50: Inhalation LC50 for a similar material was greater than 6.4 g/m3 (rats). OTHER TOXICITY DATA: From skin-painting studies of petroleum distillates of similar composition and distillate range,it has been shown that these types of materials often possess weals carcinogenic activity in laboratory animals. In these tests, the material is painted on the shaved backs of nvice twice a week for their Iifetime.The material is not washed off between applications. Therefore, there may be a potential risk of skin cancer from prolonged or repeated skin contact with this product in the absence of good personal hygiene.This particular product has not been tested for carcinogenic activity,but we have chosen to be cautious in light of the findings with other distillate streams. Occasional skin contact with this product is not expected to have serious effects, but good personal hygiene should be practiced and repeated skin contact avoided.This product can also be expected to produce skin irritation upon prolonged or repeated skin contact. Personal hygiene measures taken to prevent skin irritation are expected to be adequate to prevent risk of skin cancer. This product has a sufficiently low vapor pressure to prevent a hazardous buildup of vapors unless the product is heated, used in a confined space with inadequate ventilation or misted_Inhalation of mist or high concentrations of vapors can produce dizziness, headache,and nausea and possibly imitation of the eye, nose and throat. Aspiration of this product into the lungs can cause chemical pneumonia and can be fatal. Aspiration into the lungs can occur while vomiting after ingestion of this product. Do not siphon by mouth. Materials of this type have been shown to produce kidney damage in male rats following prolonged inhalation exposures. Following extensive research, this effect appears to be unique to the male rat and is considered to be of little or no relevance in terms of human health risk. No component of this product piesent at levels greater than 0.1% is identified as a carcinogen by NTP,IARC or OSHA.
