While both Avicel pH 101 and Avicel pH 112 are MCC products, there are some key differences between them:
1. pH Value:
- Avicel pH 101 has a pH value of approximately 10, indicating that it is slightly alkaline.
- Avicel pH 112 has a pH value of approximately 11, making it more alkaline compared to Avicel pH 101.
2. Surface Properties:
- Avicel pH 101 has a neutral surface charge, which makes it suitable for applications where minimal interaction with charged molecules or surfaces is desired.
- Avicel pH 112 has a slightly anionic surface charge, meaning it carries a negative charge. This charge can be advantageous in certain applications where specific interactions with positively charged molecules or surfaces are required.
3. Functionality:
- Avicel pH 101 is generally used as a suspending agent, binder, or filler in pharmaceutical formulations due to its neutral surface charge and inert properties.
- Avicel pH 112, with its anionic surface charge, is often preferred in applications such as chromatography, where the charged surface enhances the separation and purification of molecules based on their charge interactions.
4. Applications:
- Avicel pH 101:
- Pharmaceutical formulations (suspending agent, binder, filler)
- Tabletting
- Food thickener
- Cosmetics
- Avicel pH 112:
- Chromatography
- Ion exchange resins
- Drug delivery systems
- Water purification
The choice between Avicel pH 101 and Avicel pH 112 depends on the specific requirements of the intended application. The pH value, surface properties, and functionality of these MCC products make them suitable for a variety of industries, including pharmaceuticals, food, and cosmetics, among others.
