    pyrotechnics agriculture and recreational

    ►Description

     

        A white or colorless crystalline compound, H3BO3, either naturally

     

    occurring or made from borax. It is used as anantiseptic and preservative,

     

    and in cements, enamels, and cosmetics.

     

        Boric acid, also called hydrogen borate, boracic acid, orthoboric acid and

     

    acidum boricum, is a weak, monobasic Lewis acid of boron, which is often

     

    used as an antiseptic, insecticide, flame retardant, neutron absorber, or

     

    precursor to other chemical compounds. It has the chemical formula H3BO3

     

    (sometimes written B(OH)3), and exists in the form of colorless crystals or a

     

    white powder that dissolves in water. When occurring as a mineral, it is called

     

    sassolite.

       Boric Acid has been used since the ancient Greeks as a method to fireproof cloth.

     

    It is a mild astringent that kills bacteria and is used in eyewash to this day. It is also

     

    used as a Roach Killer. In the late 1800’s and early 1900’s it was still used as a

     

    food preservative until we found it was killing people and was banned from this use.

     

    In the past Boric Acid was used as 3% in ointment for babies diaper rash. Then we

     

    found this Boric Acid diaper rash cream made sick, caused permanent damage,

     

    and killed human infants when applied to babies diaper rash.

     

    In 1964 a researcher named Wong published some studies that Boric Acid was

     

    much more toxic than once thought, but his work was largely ignored.

     

    There are no studies that show Boric Acid is safe in mattresses. The industry

     

    claims it’s safe because we have always done it that way, and don’t know of killing

     

    anyone yet.

     

    The industry claims Boric Acid has been ‘widely’ used in mattresses for over thirty

     

    years. However, a cotton-batting manufacturer told us that none of his innerspring

     

    mattress manufacturer customers use boric acid treated cotton. Since 1973 Boric

     

    Acid treated cotton has been used in some mattresses to pass the cigarette ignition

     

    law. However, simply putting a layer of polyester or foam under the ticking passes

     

    the test without any added chemicals. Most manufacturers simply stopped putting

     

    cotton in mattresses. Those who continued usually put a thin layer polyester or

     

    foam quilted in the ticking and over the cotton batting rather than pay the 7% extra

     

    cost of treated cotton. A very small number of the very cheapest mattresses may

     

    have still used unquilted ticking with Boric Acid treated cotton directly under the

     

    ticking.

      ► Molecular and crystal structure

     

     

      The three oxygen atoms form a trigonal planar geometry around the boron. The B-

     

    O bond length is 136 pm and the O-H is 97 pm. The molecular point group is C3h.

     

    Crystalline boric acid consists of layers of B(OH)3 molecules held together by

     

    hydrogen bonds of length 272 pm. The distance between two adjacent layers is

     

    318 pm.


        Based on mammalian median lethal dose (LD50) rating of 2,660 mg/kg body

     

    mass, boric acid is only poisonous if taken internally or inhaled in large quantities.

     

    The Fourteenth Edition of the Merck Index indicates that the LD50 of boric acid is

     

    5.14 g/kg for oral dosages given to rats, and that 5 to 20 g/kg has produced death

     

    in adult humans. For comparison's sake, the LD50 of salt is reported to be 3.75

     

    g/kg in rats according to the Merck Index. According to the Agency for Toxic

     

    Substances and Disease Registry, "The minimal lethal dose of ingested boron (as

     

    boric acid) was reported to be 2–3 g in infants, 5–6 g in children, and 15–20 g in

     

    adults. However, a review of 784 human poisonings with boric acid (10–88 g)

     

    reported no fatalities, with 88% of cases being asymptomatic."Toxicology

     

    Long-term exposure to boric acid may be of more concern, causing kidney damage

     

    and eventually kidney failure (see links below). Although it does not appear to be

     

    carcinogenic, studies in dogs have reported testicular atrophy after exposure to 32

     

    mg/kg bw/day for 90 days. This level is far lower than the LD50.

     

        According to the boric acid IUCLID Dataset published by the European

     

    Commission, boric acid in high doses shows significant developmental toxicity and

     

    teratogenicity in rabbit, rat, and mouse fetuses as well as cardiovascular defects,

     

    skeletal variations, and mild kidney lesions. As a consequence in the 30th ATP to

     

    EU directive 67/548/EEC of August 2008, the European Commission decided to

     

    amend its classification as reprotoxic category 2, and to apply the risk phrases R60

     

    (may impair fertility) and R61 (may cause harm to the unborn child).

     

          At a 2010 European Diagnostics Manufacturing Association (EDMA) Meeting,

     

    several new additions to the Substance of Very High Concern (SVHC) candidate

     

    list in relation to the Registration, Evaluation, Authorisation and Restriction of

     

    Chemicals Regulations 2007 (REACH) were discussed. Following the registration

     

    and review completed as part of REACH, the classification of Boric Acid CAS

     

    10043-35-3 / 11113-50-1 is listed from 1 December 2010 is H360FD (May damage

     

    fertility. May damage the unborn child.)

     

     

     

     

     ►Application in Industry

     

     

    Pyrotechnics

     

     

    Boron is used in pyrotechnics to prevent the amide-forming reaction between

     

    aluminum and nitrates. A small amount of boric acid is added to the composition to

     

    neutralize alkaline amides that can react with the aluminum.Boric acid can be used

     

    as a colorant to make fire green. For example, when dissolved in methanol it is

     

    popularly used by fire jugglers and fire spinners to create a deep green flame.

     

    Agriculture

     

    Boric acid is used to treat or prevent boron deficiencies in plants. It is also used in

     

    preservation of grains such as rice and wheat.

     

    Recreational

     

    For the game of carrom, boric acid is sprinkled onto the board of play to act as a

     

    dry lubricant to increase the speed of the pieces when struck.
