Toxicity

Toxicity Data

• Dermal LD₅₀: believed to be >2 g/kg (rabbit) based on constituents.
• Irritation: causes eye, skin, and respiratory irritation.

Target Organ Data

• Acute: Irritation to the eyes, skin, lungs and mucous membranes. Inhalatin may produce CNS Depression and narcotic effects at high exposure concentrations.
• Chronic: In animals prolonged exposure by oral and inhalation routes of exposure to high concentrations of 5-methyl-2-hexanone has caused kidney and liver effects.
• Carcinogenicity: This product is not known or reported to be carcinogenic. A statistical increase in cancer was observed in workers exposed industrially to isopropyl alcohol manufacture by the strong acid process. The risk of laryngeal cancer may also be elevated. The specific substances responsible are not clear. Isopropyl alcohol manufacture by the strong acid process is listed by IARC as Evidence for carcinogenicity to humans and evidence for carcinogenicity to animals.

Health

Effects:

• Inhalation: Acute: If inhaled, may cause irritation to the throat, mucous membranes, upper respiratory tract, and lungs. Any irritation would be expected to be transient with no permanent damage expected. High concentratons in air may be narcotic and depress the central nervous system with symptoms including headache, breathing difficulty, dizziness, drowsiness, loss of coordination, weakness, nausea, and vomiting.

• Skin:
• 1. Acute: Skin contact would be expected to cause an irritation consisting of transient redness. This irritant effect would not result in permanent damage.
  2. Chronic: Repeated or prolonged contact may cause a defatting action on the skin leading to dermatitis. Repeated exposure may result in allergic skin sensitization in some individuals.

• Eyes: Acute:Contact with the eyes would be expected to cause an irritation consisting of reversible redness, swelling and mucous membrane discharge to the conjunctiva. No corneal involvement or visual impairment would be expected.

• Ingestion: Acute: Ingestion may cause gastrointestinal discomfort with any or all of the following symptoms: nausea, vomiting, lethargy or diarrhea. Ingestion may also cause drowsiness, headache, lowering of blood pressure and narcosis. In extreme situations, ingestion may damage the liver and kidneys.

• Medical Conditions Aggravated by Exposure: Persons with chronic respiratory or skin diseases may be at increased risk from exposure.

• Interactions with other chemicals which enhance toxicity: Pretreatment or preexposure with isopropyl alcohol may increase the hepatoxic potential of chlorinated hydrocarbons such as chloroform, 1,1,2 trichloroethane and carbon tetrachloride.

• Routes of Absorption: Inhalation, ingestion, skin, eye contact.

First Aid:

• Inhalation: If person experiences nausea, headache, or dizziness, person should stop work immediately and move to fresh air until these symptoms disappear. If breathing is difficult, administer oxygen, keep the person warm and at rest. Call a physician. In the event that an individual inhales enough product to lose consciousness, person should be moved to fresh air at once and a physician should be called immediately. If breathing has stopped, artificial respiration should be given immediately. In all cases, ensure adequate ventilation and provide respiratory protection before the person returns to work.

• Eyes: Immediately flush with large amounts of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. If eye irritation develops, call a physician.

• Skin: Immediately flush with water 15 minutes. Wash the contaminated skin with soap and water. If irritation develops, call a physician. If clothing comes in contact with the product, the clothing should be laundered before re-use.

• Ingestion: Immediately drink large quantities of water. Induce vomiting. Call a physician at once. Do not give anything by mouth if the person is unconscious or if having convulsions.
