Primary Pharmaceutical Applications
Application Role & Function
Oral Liquids Acts as a powerful suspending agent for insoluble active ingredients (syrups, suspensions), ensuring uniform dosage.
Topical Formulations Provides excellent spreadability and texture to creams, lotions, and gels without a "sticky" feel.
Controlled Release Used in tablet formulations as a matrix-forming agent to control the release rate of drugs.
Ophthalmic Drops Enhances the contact time of eye drops on the ocular surface by increasing viscosity.

Quality Standards & Compliance
To be classified as Pharma Grade, the product must typically comply with major pharmacopeia standards, including:
• USP/NF (United States Pharmacopeia/National Formulary)
Key Purity Specs:
• Loss on Drying: $\le 15\%$
• Total Ash: $\le 13\%$
• Arsenic: $\le 3$ ppm
• Lead: $\le 2$ ppm
• Microbial Limits: Strict absence of Salmonella and E. coli; low total viable count.

Why Choose Pharma Grade Over Food Grade?
While both grades are safe, Pharma Grade undergoes more rigorous testing and refining processes to ensure:
1. Lower Bioburden: Significantly lower microbial counts for use in sensitive medications.
2. Higher Consistency: Tighter control over viscosity and particle size distribution.
3. Trace Element Control: Stricter limits on heavy metals and impurities.
