Boro-glycerine is a transparent yellow, tasteless, [1] compound of boric acid and glycerine. [2] It is a powerful antiseptic and is used primarily in oral and dental applications. Historically, it was also used in the preservation of food. [2]
Boric acid is a weak acid, with pK a (the pH at which buffering is strongest because the free acid and borate ion are in equal concentrations) of 9.24 in pure water at 25 °C. But apparent p K a is substantially lower in swimming pool or ocean waters because of interactions with various other molecules in solution.
Boracic lint (/ b ɒ ˈ r æ s ɪ k /) is a type of medical dressing made from surgical lint that is soaked in a hot, saturated solution of boracic acid and glycerine and then left to dry. Medical dressing
Vaginal boric acid can be used against recurrent infections, both with C. albicans and with other species, although with C. albicans azoles are generally used instead. [ 34 ] Alternative medicine
27.5 g of boric acid (CAS# 10043-35-3) 20 ml of 0.5 M EDTA (CAS# 60-00-4) (pH 8.0) Adjust pH to 8.3 by HCl. [2] TBE can be diluted to 1X prior to use in electrophoresis, 0.5x is acceptable as well. Higher concentrations will result in poor results due to excessive heat generation.
Early work in the 1950s made use of widely available non-toxic boron compounds such as sodium borate (also known as borax) and boric acid. Sodium borate was used to treat nearly a dozen patients with BNCT through a collaboration between Massachusetts General Hospital and Brookhaven National Laboratory. [5]

Other formulations have been developed over time. In 1916, Marcel Daufresne substituted sodium bicarbonate for Dakin's boric acid as buffering agent. [7] [17] This formulation is the basis of current commercial products. [18] The concentration chosen by Dakin (0.5%) was the maximum highest concentration found tolerable to the skin.
