Hakki SS, Bozkurt SB, Hakki EE, Nielsen FH. Boron as Boric Acid Induces mRNA Expression of the Differentiation Factor Tuftelin in Pre-Osteoblastic MC3T3-E1 Cells. Biol Trace Elem Res. 2021 Apr;199(4):1534-1543. doi: 10.1007/s12011-020-02257-x.
Abstract. The effects of boron on the formation and maintenance of mineralized structures at the molecular level are still not clearly defined. Thus, a study was conducted using MC3T3-E1 cells to determine whether boron affected mRNA expressions of genes associated with bone/alveolar bone formation around the teethMC3T3-E1 (clone 4) cells were cultured in media treated with boric acid at concentrations of 0, 0.1, 10, 100, or 1000 ng/ml.
Princz J, Becker L, Scheffczyk A, Stephenson G, Scroggins R, Moser T, Römbke J. Ecotoxicity of boric acid in standard laboratory tests with plants and soil organisms. Ecotoxicology. 2017 May;26(4):471-481. doi: 10.1007/s10646-017-1789-0.
Abstract. To verify the continuous sensitivity of ecotoxicological tests (mainly the test organisms), reference substances with known toxicity are regularly tested. Ideally, this substance(s) would lack specificity in its mode action, be bioavailable and readily attainable with cost-effective means of chemical characterization. Boric acid has satisfied these criteria, but has most recently been characterized as a substance of very high concern, due to reproductive effects in humans, thus limiting its recommendation as an ideal reference toxicant.
Powell A, Ghanem KG, Rogers L, Zinalabedini A, Brotman RM, Zenilman J, Tuddenham S. Clinicians' Use of Intravaginal Boric Acid Maintenance Therapy for Recurrent Vulvovaginal Candidiasis and Bacterial Vaginosis. Sex Transm Dis. 2019 Dec;46(12):810-812. doi: 10.1097/OLQ.0000000000001063.
Abstract. A retrospective chart review characterized clinicians' use of maintenance intravaginal boric acid for women with recurrent vulvovaginal candidiasis or bacterial vaginosis. Average length of use was 13 months with high patient satisfaction and few adverse events. Prospective studies are needed to evaluate the efficacy of maintenance boric acid for these conditions.
Martinko K, Ivanković S, Đermić E, Đermić D. In vitro antifungal effect of phenylboronic and boric acid on Alternaria alternata. Arh Hig Rada Toksikol. 2022 Apr 7;73(1):83-87. doi: 10.2478/aiht-2022-73-3620.
Abstract. Due to frequent use of fungicides, A. alternata has developed resistance with negative economic and environmental consequences. Research of new ways to control fungal pathogens has turned its eye to environmentally friendly chemicals with low toxicity such as boronic acids. The aim of our study was therefore to test the antifungal effects of phenylboronic and boric acid in vitro on A. alternata.

Abstract. Epidural fibrosis is a major problem after spine surgery, with some patients having recurrent symptoms secondary to excessive formation of scar tissue resulting in neurologic compression. We used a rat laminectomy model to determine if topical application of boric acid could be helpful in the prevention of epidural fibrosis.
Ushio K, Watanabe E, Kamiya T, Nagashima A, Furuta T, Imaizumi G, Fujiwara T, Romero MF, Kato A. Boric acid transport activity of human aquaporins expressed in Xenopus oocytes. Physiol Rep. 2022 Jan;10(1):e15164. doi: 10.14814/phy2.15164.
Abstract. Boric acid transport activities of human aquaporins (AQPs) were analyzed by Xenopus oocyte swelling assay, elemental quantification, and electrophysiological analysis using a pH microelectrode. The results indicate that human AQP3, 7, 8, 9 and 10 act as boric acid channels. This is the first demonstration of identification of boric acid channels in mammals.
Sierras A, Wada-Katsumata A, Schal C. Effectiveness of Boric Acid by Ingestion, But Not by Contact, Against the Common Bed Bug (Hemiptera: Cimicidae). J Econ Entomol. 2018 Dec 14;111(6):2772-2781. doi: 10.1093/jee/toy260.
Abstract. Boric acid products, formulated as dusts, sprays, granular baits, pastes, gels, and liquids, are widely available to consumers and pest management professionals, especially to control pest infestations within homes. Boric acid dust is commonly used against bed bugs (Cimex lectularius L. [Hemiptera: Cimicidae]), but its efficacy has not been demonstrated. We evaluated the efficacy of boric acid as an ingestible and residual contact insecticide on bed bugs, and compared its efficacy on the German cockroach (Blattella germanica L. [Blattodea: Ectobiidae]) which is known to be susceptible to boric acid by both routes.

Boric acid is a naturally occurring inorganic acid that plays a direct role in calcium metabolism in mammals and is considered a vital micronutrient, however toxic at high concentrations in animals. It is hydrogen borate, a weak boron acid.
The name describes the structure of the molecule:.
Raw Materials and Their Functions
Borate Minerals. Natural sources of boron, such as boracite, sassolite, and kernite, from which boric acid can be extracted.
Water. Used as a solvent in the process of extracting and purifying boric acid from borate minerals.
Industrial Chemical Synthesis of Boric Acid
It appears in the form of a white powder consisting of colourless water-soluble crystals or an odourless white amorphous powder.
What it is used for and where
Boric Acid is commonly used as an antiseptic in pharmaceutical products, as a preservative in some ophthalmic solutions, and as an ingredient in insecticides and plant care products. It is also used in some industrial applications, such as in the manufacture of glass and ceramics.
It was originally registered in the USA as a household insecticide and is still an effective and commonly used product to control a wide range of pests in public health, agricultural, and structural settings.
Medical
It has anti-inflammatory and antioxidant properties that have made it useful in various therapies.
It has been used for decades to treat yeast vaginitis, bacterial vaginosis, recurrent vulvovaginal candidiasis, and the additional use of boric acid in non-surgical periodontal therapy has been shown to be effective in treatment at 3 and 6 months (1).
Other studies have demonstrated the efficacy of boric acid against drug-resistant Candida albicans and Candida glabrata (2).
In ophthalmology it is used as an excipient in eye drops and as a multipurpose solution for tamponaded contact lenses as a disinfectant and without cytotoxic effects (3).
Food
Ingredient listed in the European food additives list as E284, preservative.
Food safety
The Panel on Food Additives evaluated the safety of boric acid (E 284) and sodium tetraborate (borax) (E 285) as food additives in the EU. These additives are authorised in the EU for use as preservatives in sturgeon eggs (caviar) up to a maximum concentration of 4 g boric acid/kg. An ADI of 0.16 mg boron/kg body weight/day was established. The Panel concluded that boric acid and sodium tetraborate are not of concern in terms of genotoxicity (4)
Cosmetics
It is a restricted ingredient II/1395 as Relevant Item in the Annexes of the European Cosmetics Regulation No. 2019/831 (5).
Antimicrobial agent. This ingredient is able to suppress or inhibit the growth and replication of a broad spectrum of microorganisms such as bacteria, fungi and viruses by making the stratum corneum temporarily bactericidal and fungicidal.
Buffering agent. It is an iingredient that can bring an alkaline or acid solution to a certain pH level and prevent it from changing, in practice a pH stabiliser that can effectively resist instability and pH change.
Denaturant. The ionic or polar molecules of this ingredient included in formulations that interact with protein groups, modulate the properties of the solution to suit specific needs.
Other uses
Boric acid is widely used by the glass industry, particularly for glass fibres, in ceramics to improve strength and lustre. It is also used in metal welding, electronics, precious stones and scientific research.
