Classification and Labeling for Boric Acid

Boric acid is classified as a reprotoxic category-2 chemical and is labeled as an R60 and R61 drug, because it can cause damage to human fetuses as well as cause fertility problems when a person is exposed to it over a long period of time. Certain laws govern the handling and packaging of reprotoxic category-2 chemicals, particularly boric acid. When using boric acid, wear protective clothing to prevent any damage that may be caused by exposure.

  1. Sources of Boric Acid

    • Boric acid is a weak acid, which occurs naturally in geysers and in minerals that are found in areas known for frequent and regular volcanic activities. The more recent the volcanic activity, the higher the boric acid content in the area. Boric acid is also found naturally in various kinds of fruits and plants, as well as in seawater, but only in small concentrations. Boric acid is produced artificially through the interaction of hydrochloric acid on borax.

    Uses of Boric Acid

    • Boric acid absorbs low-frequency noises in seawater. When used on fruits and plants, it acts as a growth stimulator and increases the size of the plant and the quality of the fruit. Boric acid doesn't occur naturally in humans, but when used with a lotion or cream, it acts as an antiseptic lotion to treat minor burns, cuts or abrasions. It is also used as an additive in eyewash solutions but needs to be diluted substantially

    Harmful Effects of Boric Acid

    • Boric acid is generally not harmful to humans or animals when used externally. According to Medline Plus, boric acid is a dangerous poison. It can cause serious health complications when a person ingests boric acid in copious amounts. Chronic illnesses, including heart problems, kidney malfunctioning or kidney failure, occur when people are repeatedly exposed to boric acid either through inhalation or ingestion. However, boric acid has no carcinogenic effects, according to American Journal of Applied Science.

    Using Boric Acid for Control of Insects

    • In spite of the issues plaguing the safety of boric acid, it is still considered safe to be used as an insecticide in households. Boric acid affects insects such as lice, ticks and cockroaches by affecting their metabolisms and eating through their exo-skeletons. Even though it is classified as a toxic chemical, boric acid is widely used simply because it is much more poisonous to insects than to humans.

    Industrial Applications of Boric Acid

    • Boric acid is primarily used in higher concentrations and strengths in industrial applications at nuclear power plants. Boric acid rods are used as moderators, which trap subatomic particles to control the rate of fission in the reactor. They are used in the highest concentration to store spent fuel rods to prevent an uncontrolled fission reaction. Boric acid is also used in making fiberglass and glass for LCD TVs, as well as in pyrotechnics.
