Borax alone does not have a high affinity for the hardness cations, although it has been used for water-softening. Since people are already exposed to boric acid naturally through their diets and water, Health Canada advised that exposure from other sources should be reduced as much as possible, especially for children and pregnant women. [56][clarification needed], Overexposure to borax dust can cause respiratory irritation, while no skin irritation is known to exist due to external borax exposure. Borax as a source of borate has been used to take advantage of the co-complexing ability of borate with other agents in water to form complex ions with various substances. Borax is a component of many detergents, cosmetics, and enamel glazes.

[11], Borax was first discovered in dry lake beds in Tibet and was imported via the Silk Road to the Arabian Peninsula in the 8th century AD. [12] Borax first came into common use in the late 19th century when Francis Marion Smith's Pacific Coast Borax Company began to market and popularize a large variety of applications under the 20 Mule Team Borax trademark, named for the method by which borax was originally hauled out of the California and Nevada deserts.[13][14]. It is a white, odorless crystalline granular or powder … Naturally occurring borax is refined by a process of recrystallization.[22]. The name may refer to any of a number of closely related boron-containing mineral or chemical compounds that differ in their water of crystallization content. [59] If this recommendation is approved, all imports and uses of borax in the EU will have to be authorized by the ECHA. Sodium Tetraborate, Decahydrate Safety Data Sheet according to Federal Register / Vol. "[55] In the reevaluation, a study of toxicity due to overexposure was checked and the findings were that "The residential handler inhalation risks due to boric acid and its sodium salts as active ingredients are not a risk concern and do not exceed the level of concern..." but that there could be some risk of irritation to children inhaling it if used as a powder for cleaning rugs. 37, No.10 & 11 (1976), early history of food regulation in the United States, Registration, Evaluation, Authorisation and Restriction of Chemicals, Journal of Toxicology and Environmental Health, "Crystal structures of sodium sulfate decahydrate (Glauber's salt) and sodium tetraborate decahydrate (borax). Substances and mixtures imported into the EU which contain borax are now required to be labelled with the warnings "May damage fertility" and "May damage the unborn child". With this in mind, the department also announced that registrations for certain pesticides that contain boric acid, which are commonly used in homes, will have their registrations cancelled and be phased out of the marketplace. Ingestion may cause gastrointestinal distress including nausea, persistent vomiting, abdominal pain, and diarrhea. PubMed:Sensory and associated reactions to mineral dusts: sodium borate… Individual Protection Measures, Such as Personal Protective Equipment As well, new, more protective label directions are being introduced for other boric acid pesticides that continue to be registered in Canada (for example, enclosed bait stations and spot treatments using gel formulations).[61]. Its reaction with hydrochloric acid to form boric acid is: The "decahydrate" is sufficiently stable to find use as a primary standard for acid base titrimetry.[15]. [9] It is a colorless crystalline solid that dissolves in water. Boric acid is used to color methanol flames a transparent green. [58] It was proposed for addition to REACH Annex XIV by the ECHA on July 1, 2015. These all appear to be related to the Sanskrit टांकण ṭānkaṇa. That may have been from medieval Latin baurach (another English spelling), borac(-/um/em), borax, along with Spanish borrax (> borraj) and Italian borrace, in the 9th century. The term borax is often used for a number of closely related minerals or chemical compounds that differ in their crystal water content: From the chemical perspective, borax contains the [B4O5(OH)4]2− ion. Borax, sodium tetraborate decahydrate, according to one study, is not acutely toxic.

Borax alone does not have a high affinity for the hardness cations, although it has been used for water-softening. Since people are already exposed to boric acid naturally through their diets and water, Health Canada advised that exposure from other sources should be reduced as much as possible, especially for children and pregnant women. [56][clarification needed], Overexposure to borax dust can cause respiratory irritation, while no skin irritation is known to exist due to external borax exposure. Borax as a source of borate has been used to take advantage of the co-complexing ability of borate with other agents in water to form complex ions with various substances.
