1. What is Boron?
Boron (Element Symbol: B, CAS 7440-42-8) is a critical metalloid element used in nutrition, advanced materials, and industrial processes. Unlike single-source plant extracts, Boron is mined from natural mineral deposits such as Borax, Kernite, and Colemanite, and refined into highly pure compounds. In industrial and health-related applications, Boron plays a role in:
-
Dietary Supplements: supporting bone metabolism and hormonal balance (via calcium, magnesium, and steroid hormone modulation).
-
Cosmetics: acting as a pH adjuster, preservative stabilizer, and emulsifier.
-
Industrial Materials: used in fiberglass, borosilicate glass, ceramics, and aerospace composites.
