Butoxyethanol

Butoxyethanol, also known as 2-Butoxyethanol, is a widely used solvent. A colorless liquid with a sweet scent, butoxyethanol is primarily used in paints and coatings, and also is an ingredient some household cleaning products, cosmetics and personal care products.

Uses & Benefits

Household Cleaning Products

Common household cleaning products like glass cleaners, liquid soaps and all-purpose spray-cleaners contain butoxyethanol, for its ability to help dissolve substances such as grease and dirt.

Personal Care Products

Cosmetic products such as hair dyes, nail polishes, nail polish removers and skin cleansers contain butoxyethanol, which can help prevent the other product ingredients from separating within the formulation. Butoxyethanol also can help keep a substance clear—even after a product is exposed to extreme temperatures during shipping or storage.

Solvents and Adhesives

One of the main industrial uses of butoxyethanol is as a solvent in protective surface coatings, such as spray lacquers, quick-dry lacquers and enamels, as well as water-based varnishes and latex paints. Butoxyethanol helps decrease the overall thickness of a varnish or paint to help enable smoother application. Butoxyethanol is also an ingredient in adhesives and inks used on food packaging.

Safety Information

For using cleaning products containing butoxyethanol in the home, follow safe handling instructions included on the label to minimize potential exposure.

The Cosmetic Ingredient Review (CIR), an expert scientific panel sponsored by the Personal Care Products Council has assessed the safety of butoxyethanol in personal care products, concluding that butoxyethanol is safe in hair and nail products at concentrations at low levels (<10%) – per CIR’s recommendation. The CIR found that even at the maximum concentration of 10 percent, water-based butoxyethanol did not cause skin irritation in a patch test involving 201 subjects.

Exposures to butoxyethanol are more likely to occur in the workplace, for example in spray-painting operations or automobile repair shops, rather than in the environment or at home. To help protect workers who use butoxyethanol in occupational settings, the U.S. Occupational Safety and Health Administration (OSHA) has set an exposure limit of 50 parts of 2-butoxyethanol per million parts of air (50 ppm) for an 8-hour workday, 40-hour workweek.

Butoxyethanol is also regulated under the Clean Air Act, including the National Emission Standards for Hazardous Air Pollutants.

According to the U.S. Agency for Toxic Substances & Disease Registry (ATSDR), inappropriately or accidentally swallowing large amounts of cleaning agents containing butoxyethanol can cause harmful effects for people. Those could include breathing problems, low blood pressure, lowered levels of hemoglobin, blood in the urine, and metabolic acidosis (high levels of acid in the body).

Answering Questions

What are the uses of butoxyethanol?

Butoxyethanol is a solvent in spray lacquers, enamels, varnishes, and latex paints due to its ability to clean grease and dirt. It is also a common ingredient in in liquid soaps and cosmetics, as well as industrial and household cleaning products.

Is butoxyethanol harmful or dangerous to people?

According to ATSDR, inappropriately or accidentally swallowing large amounts of cleaning agents containing butoxyethanol can cause harmful effects. These could include breathing problems, low blood pressure, lowered levels of hemoglobin, blood in the urine, and metabolic acidosis (high levels of acid in the body).

There are no data on whether butoxyethanol causes reproductive effects, birth defects, or cancer in people, according to ATSDR. Some harmful effects of 2-butoxyethanol have been seen in animals such as rats and rabbits. No studies have been found that tested butoxyethanol for causing cancer in animals, according to ATSDR.

Cleaning products with butoxyethanol can be effective in cleaning grease and dirt, and can be used safely by following instructions on a product’s label. As with other cleaning products, keep household products containing 2-butoxyethaol out of the reach of children to avoid accidental ingestion.
