Most people associate borax cleaner with mule teams and mining operations in Death Valley, California, where the mineral has formed white crystals over time through concentration of run-off from surrounding hills. Borax is also mined from deep in the earth in Turkey and Tibet. It was a mainstay of laundry rooms in the 1950s, prized for it's buffering and bleaching action when combined with water. Borax kills fungus and mold. Boraxo, a Dial Corporation product, is an abrasive hand cleaner.
Borax is Versatile but has Valid Consumer Concerns
Borax is slightly alkaline, so it lends itself well to natural skin cleansers and toners. Combined with soap, it makes an effective exfoliator to remove dead skin cells and bacteria and oil that hide under them and cause acne. Mixed with beeswax, borax is an emulsifier in many creams and lotions.The FDA currently lists borax as generally considered safe, but one of the agency's committees recommended restricting the use of borax in consumer products.
Differences Between Borax and Boric Acid
Borax is known as sodium tetraborate decahydrate. Boric acid’s scientific name is boron trihydroxide. Although boric acid and borax both contain boron, they are different molecular compounds. Both compounds are toxic if ingested.
Boric acid is marketed for its insecticidal properties. It kills roaches, ants and fleas. Although boric acid naturally occurs in soil and is needed as a trace mineral by plants, excessive use of the mineral kills them, making this product a good herbicide. Boric acid solution was once a popular eyewash, but is not recommended for any medical use now. According to the U.S. National Institute of Health, "Chronic poisoning occurs in those who are repeatedly exposed to boric acid. For example, in the past, boric acid was used to disinfect and treat wounds. Patients who received such treatments over and over again got sick, and some died." One safe use of boric acid is as a homeopathic remedy, for acne and anti-fungal preparations, including vaginal suppositories for yeast infection treatment. Homeopathic remedies are so dilute they do not contain active pharmacological molecules of boric acid.
Sodium borate is an ingredient in the HPV vaccine Gardisil, which is marketed to young women as a preventative against one type of cervical cancer caused by the human papillomavirus. Sodium borate is also marketed as rat poison, although in much higher doses. Gardisil manufacturer Merck says the amount of sodium borate used to preserve the vaccine is safe.
Washington Times reporter Gregory Lopes, however, noted that some possible vaccine reactions that have prompted authorities in Spain to stop distributing the shots are eerily similar to symptoms of sodium borate poisoning: headaches, blurred vision, possible seizures and paralysis. Most of the reactions were mild and temporary but two young women were hospitalized after taking the vaccine.
Dangers of Exposure
The following information is listed under Hazard Identification of the Material Safety Data Sheet for 20 Mule Team Borax:
“Ingestion: May be harmful if swallowed. Products containing Borax are not intended for ingestion. Borax has a low acute toxicity. Small amounts (e.g., a teaspoon) swallowed accidentally are not likely to cause effects; swallowing amounts larger than that may cause gastrointestinal symptoms.
Reproductive/developmental: Suspected of damaging fertility or the unborn child. Animal ingestion studies in several species, at high doses, indicate that borates cause reproductive and developmental effects. A human study of occupational exposure to borate dust showed no adverse effect on reproduction. Target organs: No target organ has been identified in humans. High dose, animal ingestion studies indicate the testes are the target organs in male animals. Signs and symptoms of exposure: Symptoms of accidental over-exposure to Borax might include nausea, vomiting and diarrhea, with delayed effects of skin redness and peeling. These symptoms have been associated with the accidental overexposure to the chemically related substance boric acid.”
Boric Acid is a Neurotoxin
Birth defects that can be caused by boric acid include brain and skeletal abnormalities and infertility of male offspring. According to the U.S. Environmental Protection Agency, animal studies have shown that boric acid has an affinity for male testicles: "It appears that males are most sensitive to boric acid/boric salts. A major target... is the testes." Poisoning produces inflammation and atrophy of tubules and lowers sperm count.
Repeated low dose exposure to boric salts used as a food preservative in imported noodles, steamed rice, caviar and meatballs, has been implicated in cases of liver cancer over five to ten years. Boric salts have been banned as a preservative for food in the United States and many other countries, but they are still used illegally.
Take Precautions
Follow label directions when using boric acid as an herbicide or insecticide. Do not use any form of borax near food or water and keep it out of the reach of children and pets. Thorough rinsing from skin and laundry is important, and borax should not be used around eyes or mucus membranes. Pregnant women should limit exposure.
