- Cosmetic Ingredient Review Conclusion: The Expert Panel concludes that Sodium Borate and Boric Acid, in concentrations less than or equal to 5 percent, are safe as cosmetic ingredients when used as currently recommended; however, cosmetic formulations containing free Sodium Borate or Boric Acid at this concentration should not be used on infant skin or injured skin. Note: In 2003, the CIR Expert Panel considered available new data on these ingredients and reaffirmed the above conclusion. Source: Cosmetic Ingredient Review (CIR)
- Cosmetic Ingredient Review Finding(s): Safe for use in cosmetics, with qualifications Source: Cosmetic Ingredient Review (CIR)
- Environmental Bioconcentration: In a greenhouse experiment with sandy loam soil treated with 0-8.0 ppm boron as borax, boron toxicity symptoms appeared earliest in lentil plants and barley seedlings exposed to 8.0 ppm boron. In barley the severity of boron toxicity decreased with the decrease in boron levels, whereas in lentil the severity of the symptoms eventually reached the same level in 2 and 4 ppm boron treatments as with the highest concentration. Dry matter yield decreased 38.6% in lentil and 23.4% in barley exposed to 8.0 ppm boron in comparison with controls. Boron contents of lentil and barley plants on soil treated with 8 ppm boron were approximately 7- and approximately 8-fold those of control plants, respectively.

- Environmental Fate: TERRESTRIAL FATE: Boron is naturally occurring and ubiquitous in the environment. No microbial degradation. Disappearance from soil is by washing out. Persistence in soil is about 2 years, depending on rainfall and soil structure. Source: Hazardous Substances Data Bank (HSDB)

- Sources/Uses: Used as a preservative, antiseptic and fungicide; also used to manufacture glazes, enamels, soldering fluxes and cleaning compounds and to fireproof textiles and wood; [ACGIH] Boric acid and borates as tablets or powder are used to kill larvae in barns and other insects in houses. Rarely, they are sprayed as herbicides. [EPA: Recognition of Pesticide Poisonings] Used in photo developing bath; [www.ci.tucson.az.us/arthazards/medium.html] Borax (borax decahydrate) is found naturally in some salt lakes and alkaline soils.
