Unleashing Potential: Assuring Quality with Superior Powder Cellulose Analysis

CD BioGlyco offers a wide range of Pharmaceutical and Biological Analysis Services. With our advanced technology and experienced experts, we conduct a comprehensive evaluation of the properties and functionality of powdered cellulose. Powdered cellulose is a form of cellulose, which is made from cellulose. It is a substance with the same properties as cellulose and microcrystalline cellulose. It has wide applications in the pharmaceutical field as a pharmaceutical excipient. Powdered cellulose is a white or nearly white, odorless, tasteless powder that is non-toxic and non-irritating. Its molecular weight varies as the length of the molecular chain varies. The following is a detailed introduction to our analysis services for powdered cellulose.

• Identification

We use a variety of identification methods to ensure the authenticity and accuracy of powdered cellulose.

• Appearance identification: We observe the color, shape, and texture of powdered cellulose with the naked eye to initially determine whether it meets the standards.
• Chemical color reactions: We verify the chemical properties of powdered cellulose through specific chemical color reactions.
• Relative viscosity analysis: We use a viscometer to test the kinematic viscosity and calculate the relative viscosity. Then, it is judged whether the quality of powdered cellulose meets the standard by comparing it with the intrinsic viscosity table.
• Instrumental analysis: We use infrared spectroscopy (IR), nuclear magnetic resonance (NMR), and mass spectrometry (MS) to analyze the molecular structure of powdered cellulose.

• Analysis of important indicators

We strictly control and analyze multiple important indicators of powdered cellulose to ensure its quality is stable and reliable.

• pH: We use a pH meter to measure the pH of powdered cellulose to ensure it meets the specified pH range.
• Solubility: We tested the solubility of powdered cellulose in different solvents to evaluate its suitability for use in pharmaceutical formulations.
• Soluble content in ether and water: When it comes to ether and water-soluble matter content, we measure the soluble content of powdered cellulose in ether and water through a specific extraction method.
• Weight loss on drying: We use the drying method to measure the weight loss of powdered cellulose under specific conditions to determine its degree of dryness.
• Heavy metals: We use atomic absorption spectrometry or inductively coupled plasma-MS to determine the heavy metal content in powdered cellulose.

• Purity analysis

Purity is one of the important quality indicators of powdered cellulose as a pharmaceutical excipient. We use multiple methods to analyze its purity comprehensively.

• Ignition residue: We ignite powdered cellulose at high temperatures and measure its residue content to evaluate its purity.
• High-performance liquid chromatography (HPLC): We use HPLC to separate and detect powdered cellulose and analyze its purity and impurity content.
• Gas chromatography: We use gas chromatography to separate and measure the volatile components in powdered cellulose to assess its purity.

• Other analysis

In addition to the above analysis services, we also provide the following other analysis services to meet the different needs of our clients:

• Particle size analysis: We use a laser particle size analyzer to analyze the particle size distribution of powdered cellulose to evaluate its particle size and uniformity.
• Microbial limit inspection: We conduct microbial limit inspection on powdered cellulose to ensure that it meets the microbial limit standards.
• Stability analysis: We conduct long-term stability studies on powdered cellulose under different conditions to evaluate its stability and shelf life.

Frequently Asked Questions

• What are the functions of powdered cellulose as a pharmaceutical excipient?

Powdered cellulose is primarily used as a diluent in tablets and hard capsules to increase the volume of formulations that contain too little drug. In addition, it is used to reduce the settling rate of oily suspension-filling liquids in soft capsules. At the same time, powdered cellulose is also used as an excipient for powders, a suspending agent for oral aqueous suspensions, and to reduce drug sedimentation in the preparation of suppositories.

It is worth noting that, unlike the properties of general powdered cellulose, powdered cellulose with low crystallinity can be used as an excipient for direct compression.

• What impact does the weight loss on drying of powdered cellulose have on pharmaceutical formulations?

The weight loss on drying of powdered cellulose is one of the important indicators to evaluate its drying degree. Excessive weight loss on drying may cause problems such as moisture absorption and agglomeration in pharmaceutical preparations during storage and use, affecting the stability and effectiveness of the drug. Therefore, by measuring the drying weight loss of powdered cellulose, we judge whether its drying degree meets the requirements, thereby ensuring the quality and stability of pharmaceutical preparations. At the same time, the results of weight loss on drying can also provide an important reference for the preparation process of pharmaceutical preparations.
