Storage & Shelf-life
This enzyme has been formulated for optimal stability. Typical shelf-life is six months provided it is stored below 25°C (77°F) in its original packaging, sealed and unopened, protected from the sunlight. Its shelf-life will be eighteen months if it is stored properly at 0~10°C(32~50°F). Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement.
Safe Handling of Enzymes
Inhalation of enzyme dust and mists should be avoided. In case of contact with skins or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the Safety Data Sheet.
