Potential health effects

This product is a physical mixture. The health effects information about this product is based on the individual ingredients: >>>n-Methylpyrrolidone INHALATION may cause irritation of the nose and throat with sneezing, sore throat or runny nose; or non-specific effects such as headache, nausea and weakness. SKIN CONTACT may cause skin irritation with itching, burning, redness, swelling or rash. Human experience or case reports have identified the following POTENTIAL EFFECTS FROM OVEREXPOSURE: Prolonged contact may cause severe skin irritation with burning, redness, swelling, pain, blisters, cracking, or rash. There are inconclusive or unverified reports of human sensitization. Skin permeation may occur in amounts capable of producing the effects of systemic toxicity. EYE CONTACT may cause eye irritation with tearing, pain or blurred vision. Low vapor concentrations did cause eye irritation in some individuals. >>>Aromatic Hydrocarbon ****Toxic effects described in animals include: BY SKIN OR EYE CONTACT: Skin photosensitization; Moderate skin irritation; Slight eye irritation; BY INHALATION: Respiration rate changes; Tremors; Incoordination; Salivation; Hyperactivity; Nonspecific effects, e.g., weight loss and irritation. ****Human health effects of overexposure may include BY SKIN OR EYE CONTACT Skin irritation with discomfort or rash; Eye irritation with discomfort, tearing, or blurring of vision; BY INHALATION: Irritation of the upper respiratory passages with coughing and discomfort; BY INGESTION: Nonspecific discomfort, e.g., nausea, headache or weakness; Temporary nervous system depression with anaesthetic effects, e.g., dizziness, headache, confusion, incoordination, and loss of consciousness. ***In addition: Skin contact may cause photosensitization in susceptible individuals. >>>Polyamic acid of Benzophenone Tetracarboxylic Dianhydride/4,4-Oxydianiline/m-Phenylenediamine (Polymer) ****Toxic effects described in animals include: BY SKIN OR EYE CONTACT: Skin irritation; Skin sensitization; Eye irritation. >>>1-Methoxy-2-Propanol ****Toxic effects described in animals include: BY SKIN OR EYE CONTACT: Slight skin irritation; Eye irritation; Central nervous system effects; BY INHALATION: Central nervous system effects; Liver effects; Lung effects. Toxic effects of repeated or prolonged animal exposures include: BY SKIN OR EYE CONTACT: Kidney effects; Death; BY INHALATION: Continued) Central nervous system effects; Lower weight gain; Liver effects; Kidney effects; BY INGESTION: Weight loss; Central nervous system effects; Kidney effects; Liver effects; ****Additional animal tests have shown: Developmental toxicity at dosage levels showing maternal toxicity; No reproductive toxicity. ****Human health effects of overexposure may include BY SKIN OR EYE CONTACT Skin irritation with discomfort or rash; Eye irritation with discomfort, tearing, or blurring of vision; BY INHALATION: Irritation of the upper respiratory passages with coughing and discomfort; BY INGESTION: Temporary nervous system depression with anaesthetic effects, e.g., dizziness, headache, confusion, incoordination, and loss of consciousness. ***In addition BY SKIN OR EYE CONTACT Skin permeation can occur in amounts capable of producing effects of systemic toxicity. >>>1,2,4-Trimethylbenzene of overexposure may include BY SKIN CONTACT: Skin irritation with discomfort or rash; BY EYE CONTACT: Eye irritation with discomfort, tearing, or blurring of vision; BY INHALATION: Temporary nervous system depression with anaesthetic effects, e.g., dizziness, headache, confusion, incoordination, and loss of consciousness; Temporary lung irritation effects with cough, discomfort, difficulty breathing or shortness of breath; Asthma-like reactions with shortness of breath, wheezing, or cough, and possibly occurring on subsequent re-exposure to concentrations below established exposure limits. In addition BY SKIN CONTACT There are no reports on human sensitization. Individuals may have increased susceptibility to the hazards of overexposure to ingredient(s) of this product if they have pre- existing diseases of the: Central nervous system; Liver. Carcinogenicity Information None of the components present in this material at concentrations equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH as a carcinogen. ----------------------------------------------------------------------
