THE STORY OF FC BORIC ACID
FC Boric Acid: The Classic pH Regulator & Antimicrobial Aid
FC Boric Acid (H₃BO₃) is a traditional cosmetic and pharmaceutical raw material used forpH regulation, buffering, odor control, and mild antimicrobial support. It has long been used in eye washes, foot powders, skin lotions, bath products, and cleansing formulations where pH balance and preservative-boosting are required.
Refined from Boron Minerals for High-Purity Cosmetic Use
FC Boric Acid is produced by refining naturally occurring borate minerals(such as borax or kernite), followed by controlled crystallization to achieve cosmetic-grade purity. TRCkem supplies fine, low-impurity boric acid with consistent pH control properties suited for topical and personal-care formulations.
Buffer. Deodorize. Support Stability.
Functional benefits in formulations:
✅ Helps stabilize pH in mildly acidic or neutral products
✅ Acts as a deodorizing and odor-control agent
✅ Provides mild antifungal and antibacterial support in powders and washes
✅ Improves preservative efficacy in water-based systems
Commonly found in: antiseptic powders, bath salts, foot care, eyewash solutions, skin lotions, barrier creams, and medicated cleansers.
