Question
What are the required storage conditions (cold storage vs. normal room temperature) for the following product?
Product: Nanocellulose Crystal (500 gram)
- D50: 0.1-1 micron
- Length (L): 100-1000 nm
- Width (W): 1-20 nm
- Concentration: 2-5%
Answer
The Nanocellulose Crystal (2-5% dispersion) is an aqueous product. While it may be stable at normal room temperature for a period, for long-term storage and to best maintain its stability and prevent microbial growth, it is generally recommended to store it in a cool, dry place, away from direct sunlight.
Refrigeration (e.g., 4-8°C) is often preferred for aqueous nanocellulose dispersions to maximize shelf life and stability.
Crucially, avoid freezing the product, as this can damage the nanostructure and lead to irreversible aggregation.
