However, the powder’s integrity depends on the prevalent storage conditions. It is highly recommended to store in temperatures between 4°C to 49°C/35°F to 120°F (ideal storing temperature is 20°C +/- 2°C/64.4°F to 71.6°F), dry places (60% +/- 5% relative humidity), avoid sudden weather conditions changes, do not stack the pallets, handle the packages with care and maintain the product in its original, tight sealed packaging until use.
