Only the Conventional Cotton Mattresses and Hemp Mattress use Borate powder (boric acid) as a flame retardant. Is this toxic?
Boric treated cotton (with 10 to 14 percent boric acid by weight) passes FR 1647, the Federal Flammability Standard also called the cigarette smolder test. The study, done by Intertox, Inc. of Seattle, WA, presents conclusive proof that boric acid, under the specific trade name Boron#10TM, which is sodium polyborate, is not toxic. The studies tested to look for adverse health effects on the The test showed that it has a toxicity level similar to table salt. The report states, “Four of the six studies reviewed indicate no observed adverse health effects from exposure of the test animals to the Boron#10TM 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#10TM was successfully established. Many boron compounds exists naturally throughout our environment, including fruits, vegetables, and water which are digested daily in small amounts by humans. This report, A Review of Gen
