1. General introduction to Boric Acid

Boric acid is a high-purity inorganic compound widely recognized for its bacteriostatic properties (inhibiting microbial growth) and its broad applications across pharmaceutical, agricultural, and industrial sectors. In modern formulation science, boric acid is not only considered a chemical raw material but also a functional active ingredient that helps stabilize microbial environments, regulate pH, and maintain overall formulation integrity.

2. Active substance of Boric Acid

• Chemical formula: H₃BO₃
• Molecular weight: 61.83 g/mol
• Purity: ≥ 99% – 99.5% depending on grade
• Appearance: White crystalline powder
• Solubility: Soluble in water, ethanol and glycerol
• Characteristic: Weak Lewis acid with bacteriostatic activity

Its molecular structure allows boric acid to interact with microbial environments, supporting the inhibition of bacterial growth under controlled formulation conditions.

3. Key advantages of Boric Acid

• Bacteriostatic activity: Boric acid inhibits the growth of microorganisms under controlled formulation conditions, helping maintain microbial stability in pharmaceutical and industrial systems.
• High chemical stability: Its stable inorganic structure ensures consistent performance across production batches, reducing variability in large-scale manufacturing.
• Ophthalmic solutions and contact lens care solutions: Boric acid functions as a buffering agent, helping to maintain formulation pH, enhance active ingredient stability, and support the sterility of high-quality ophthalmic products.
• Broad formulation compatibility: It is highly compatible with active pharmaceutical ingredients and agricultural nutrient systems, enabling flexible formulation design.
• GMP-compliant suitability: It meets the requirements of controlled manufacturing systems with strict quality assurance and high reproducibility standards.

4. Applications of Boric Acid

In pharmaceuticals

• Topical antiseptic products: Boric acid is used in mild antiseptic formulations to help control microbial activity on skin and external surfaces.
• Ophthalmic solutions: It is applied in eye wash and ocular formulations to maintain stability and biocompatibility.
• Dermatological products: Boric acid acts as a pH-stabilizing agent, supporting formulation stability in topical creams, gels, and skincare products.
• Vaginal solutions and pessaries: Boric acid is used as an active pharmaceutical ingredient (API) for the treatment of Candida infections, owing to its potent antifungal activity while preserving the normal vaginal microbiota.

In agriculture

• Essential micronutrient source: Provides boron, a key element for cell wall development and plant reproductive growth.
• Crop yield improvement: Supports flowering and fruit set processes, improving crop quality and productivity.
• Foliar fertilizer applications: Used in foliar spray systems to enhance rapid boron uptake by plants.
• Micronutrient deficiency correction: Helps prevent and correct boron deficiency in sensitive crop species.
