Boric Acid Powder (99%) is extracted from borax, which is a naturally occurring mineral and is also termed as the weak acid of boron. At room temperature, it appears as colorless or white granules. Lab grade chemicals possess reasonable purity but do not comply with any official standard for quality or purity. Our laboratory-grade Boric Acid Powder is mostly suitable for educational and research purposes. Due to its impurities, it is not recommended for food, drug, or medicinal applications.  

You can buy boric acid in a powder form or a liquid form (aqueous solution) at LabAlley.com/collections/boric-acid. Purchase boric acid liquid here.

Boric Acid For Cosmetics And Skincare

Sodium Borate and Boric Acid prevent or retard bacterial growth, and thus protect cosmetics and personal care products from spoilage. They are also used to control pH and to minimize the change in the pH of a solution when an acid or a base is added. 

Boric acid is a weak, water-soluble acid that is mined from the mineral sassolite. It exists in the form of white crystals or powder, and possesses astringent properties that allow it to function as a cosmetic preservative. By implementing boric acid into skincare formulas, personal care products can deter bacteria formation and hinder contamination, thereby prolonging the longevity of products.

Other ways in which boric acid also works as a product stabilizer include pH adjusters, emulsifiers, buffers, and viscosifiers. With its prominent role in skincare formulations, studies show boric acid to possess very low skin absorption, which makes it safe for topical application. In skincare, boric acid’s stabilizing properties are frequently paired with glycerin’s moisturizing capabilities to ensure longer lasting product quality. For these reasons, boric acid can most commonly be found in lotions and creams.

Medical Uses Of Boric Acid

Boric acid can be used as an antiseptic for minor burns or cuts and is sometimes used in salves and dressings, such as boracic lint. Boric acid is applied in a very dilute solution as an eye wash. Dilute boric acid can be used as a vaginal douche to treat bacterial vaginosis due to excessive alkalinity, as well as candidiasis due to non-albicans candida.

Boric acid medications are affordable to most Americans. Medicines, such as vaginal suppositories made with boric acid can be purchased at CVS. 

As an antibacterial compound, boric acid can also be used as an acne treatment. It is also used as prevention of athlete's foot, by inserting powder in the socks or stockings. Various preparations can be used to treat some kinds of otitis externa (ear infection) in both humans and animals. The preservative in urine sample bottles in the UK is boric acid.

Treating Trichomoniasis With Boric Acid

Trichomoniasis (or “trich”) is a very common sexually transmitted disease (STD). It is caused by infection with a protozoan parasite called Trichomonas vaginalis. Although symptoms of the disease vary, most people who have the parasite cannot tell they are infected. The microbicidal effect of boric acid on T. vaginalis, coupled with its previous clinical use in treating vaginal candidiasis, supports the continued inclusion of boric acid in the therapeutic arsenal for treating trichomoniasis.

Boric Acid For Cleaning And Making Soap

Borate use in the world of cleaning can be traced back to Death Valley Days and the emergence of 20 Mule Team Borax brand in the late 1880s and 90s.  This came about when Francis Marion Smith who owned Pacific Coast Borax Company distributed this borax brand across the country and abroad.  This brand found use in laundry care items and as a supplement for soap and later synthetic detergents.  From there the benefits of borates grew to numerous applications including personal care products.

Pure borax can be sprinkled on clothes in the laundry machine to get them whiter. It can also be mixed with washing soda and a bar of soap to make homemade laundry detergent. Borax also makes a natural household cleaner when mixed with water in a spray bottle. As a laundry additive, borax provides moderate alkalinity buffering and aids in loosening soils and stains.

Insecticidal Used Of Boric Acid

Boric acid was first registered in the US as an insecticide in 1948 for control of cockroaches, termites, fire ants, fleas, silverfish, and many other insects. The product is generally considered to be safe to use in household kitchens to control cockroaches and ants. It acts as a stomach poison affecting the insects' metabolism, and the dry powder is abrasive to the insects' exoskeletons. Boric acid also has the reputation as "the gift that keeps on killing" in that cockroaches that cross over lightly dusted areas do not die immediately, but that the effect is like shards of glass cutting them apart. This often allows a roach to go back to the nest where it soon dies. Cockroaches, being cannibalistic, eat others killed by contact or consumption of boric acid, consuming the powder trapped in the dead roach and killing them, too.

Overview Of Boric Acid

Millions of people have washed their hands with borax soap, washed their clothes in borax, and used boron compounds to kill ants.

Boric acid, also called hydrogen borate, boracic acid, and orthoboric acid is a weak, monobasic Lewis acid of boron. Boric acid 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 is a member of boric acids. It has a role as an astringent. It is a conjugate acid of a dihydrogenborate. Boric acid is an odorless white solid.  Boric acid, also known as hydrogen borate, is a weak monobasic Lewis acid of boron with the chemical formula H3BO3.

Boric acid is typically utilized in industrial processing and manufacturing, but is also used as an additive in pharmaceutical products, cosmetics, lotions, soaps, mouthwash, toothpaste, astringents, and eyewashes. It is known to exhibit some antibacterial activity against yeast infections such as bacterial vaginosis and candidiasis.

Safety and Handling

Boric Acid Toxicology

Boric acid is only poisonous if taken internally or inhaled in large quantities. Long-term exposure to boric acid may be of more concern, causing kidney damage and eventually kidney failure.Although it does not appear to be carcinogenic, studies in dogs have reported testicular atrophy after exposure. 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.

Boric Acid Safety And Hazards

Boric acid is typically safe for humans when used as intended. Boric acid should not be ingested. 

Boric acid is low in toxicity if eaten or if it contacts skin. However, in the form of borax, it can be corrosive to the eye. Borax can also be irritating to the skin. People who have eaten boric acid have had nausea, vomiting, stomach aches, and diarrhea.

Boric Acid (Orthoboric Acid) is an "EPA Safer Chemical". Biric Acid has met the Safer Choice Criteria for its functional ingredient-class, but has some hazard profile issues. Specifically, a chemical with this code is not associated with a low level of hazard concern for all human health and environmental endpoints. While it is a best-in-class chemical and among the safest available for a particular function, the function fulfilled by the chemical should be considered an area for safer chemistry innovation. Although no adverse effects have been reported from inhaling boric acid dust, it is absorbed through mucous membranes. Ingestion of 5 grams or more may irritate gastrointestinal tract and affect central nervous system. Contact with dust or aqueous solutions may irritate eyes; no chronic effects have been recognized, but continued contact should be avoided. Dust and solutions are absorbed through burns and open wounds but not through unbroken skin. Boric acid solutions used as an eye wash or on abraded skin are known to be toxic, particularly to infants, especially after repeated use; this is because of its slow elimination rate. Boric Acid is not combustible although it does give off irritating or toxic fumes (or gases) in a fire. Boric Acid is an irritant to skin in dry form.

Exactly what I needed!

Came in a large screw on lid plastic jar and is more the consistency of sand than powder. I have used actual powder boric acid before abs definitely prefer this one with the larger grains. It isn’t messy, doesn’t float into the air and 100x easier to put into capsules that the finer powder. I used it to make suppositories and it has work wonders for chronic bv. I also sprinkled a bit around the yard because it is winter and ants tend to make there way inside and I have seen a significant reduction in critters. Love that I can get the 5lb size.
