WHAT FLAME RETARDANT DO YOU USE TO TREAT THE MATTRESSES?

  • Mattresses not wrapped in wool are treated with Boric Powder.
  • About Boric Powder:  A study done by Intertox, Inc. of Seattle, WA, presents conclusive evidence that boric acid, under the specific trade name Boron#10(TM), which is sodium polyborate, is not toxic. The report states, "Four of the six studies reviewed indicate no observed adverse health effects from exposure of the test animals to the Boron#10 added to cotton batting." Richard Pleus, the author of the report also stated that in an oral toxicity study a benchmark toxicity measure, LD50, for the product Boron#10 was successfully established.
    The LD50, defined as the dose of a compound that would be lethal for 50% of a group of test animals, was extrapolated to be 3,339 mg/kg, a number similar to the toxicity of table salt.
