Propiedades y Efectos Sobre la Salud

Summary
Exposure to Stoddard solvent occurs mainly in the workplace. People who breathe Stoddard solvent can experience headaches; dizziness; and eye, skin, or throat irritation.

What is Stoddard solvent?
Stoddard solvent is a colorless, flammable liquid that smells and tastes like kerosene. It will turn into a vapor at
temperatures of 150–200 °C. Stoddard solvent is a petroleum mixture that is also known as dry cleaning safety solvent, petroleum solvent, and varnoline; its registered trade names are Texsolve S® and Varsol 1®. It is a chemical mixture that is similar to white spirits. Stoddard solvent is used as a paint thinner; in some types
of photocopier toners, printing inks, and adhesives; as a dry cleaning solvent; and as a general cleaner and degreaser.

What happens to Stoddard solvent when it enters the environment?
Because Stoddard solvent is a mixture of many chemicals, these chemicals may react differently in the environment. Some of these chemicals can: Be broken down by sunlight or other chemicals in the air; Attach to particles in soil or water; Sink down to the sediment in water; and be broken down by microorganisms in water, soil, or sediment. It is not known whether Stoddard solvent will build up in plants or animals living in contaminated soil or water, but some of the chemicals that make up Stoddard solvent might build up in these situations.

How might I be exposed to Stoddard solvent?
Using products containing Stoddard solvent such as a paint or paint thinner, and breathing the vapors, or getting
the vapors in your eyes. Breathing contaminated air where Stoddard solvent is manufactured, used, or spilled. Breathing contaminated air at or near hazardous waste sites. Drinking or bathing in contaminated water. Ingesting contaminated soil or water near waste sites containing Stoddard solvent. Touching contaminated soil or water.

How can Stoddard solvent affect my health?
Most of the information on the health effects of Stoddard solvent comes from studies in which it is breathed; there are fewer studies of exposure to the eyes or skin. Exposure to Stoddard solvent in the air can affect your nervous system and cause dizziness, headaches, or a prolonged reaction time. It can also cause eye, skin, or throat irritation. Rats, cats, and dogs that breathed in large amounts of Stoddard solvent for several hours suffered seizures. Breathing Stoddard solvent has caused bronchitis in guinea pigs, but neither seizures nor bronchitis have been reported when humans breathed it. The effects of swallowing Stoddard solvent are not known. It is not known whether Stoddard solvent can cause birth defects or affect reproduction.

How likely is Stoddard solvent to cause cancer?
The International Agency for Research on Cancer (IARC) has determined that Stoddard solvent is not classifiable as to its carcinogenicity to humans. Very few studies have been located that study the carcinogenic effects of Stoddard solvent in humans or animals.

Is there a medical test to show whether I've been exposed to Stoddard solvent?
There is no routinely used test to show whether you have been exposed to Stoddard solvent. Because Stoddard solvent is a mixture of many chemicals, some of these chemicals can be detected in your breath, blood, urine, and fat. However, the tests cannot tell you if you have been exposed to the specific mixture of chemicals found in Stoddard solvent. They also cannot tell whether you will suffer any health effects.

Has the federal government made recommendations to protect human health?
The Occupational Safety and Health Administration (OSHA) has set a maximum exposure limit of 500 parts of Stoddard solvent per 1 million parts of air (500 ppm) for an 8­hour workday, 40-hour workweek. The National Institute for Occupational Safety and Health (NIOSH) recommends that the average workplace air levels not be more than 60 ppm in workplace air for a 10-hour workday, 40-hour workweek.
