No Clumping

Polifar exports a large quantity of citric acid annually. As a high-quality citric acid supplier, we have long supplied TTCA citric acid, Ensign citric acid, and RZBC citric acid. We have also encountered customer complaints regarding clumping in monohydrate citric acid.

However, this issue has been resolved by the Polifar team. Polifar discovered that the clumping was likely caused by inadequate moisture control during the production process, crystal particle size, and insufficient control over the drying process. After communicating with the citric acid factory, the manufacturer resolved the problem.

To prevent citric acid from absorbing moisture and clumping after production, the manufacturer ensures airtight packaging as soon as possible and further optimizes the packaging. During transportation, staff are repeatedly reminded to avoid direct sunlight on the containers, and insulation and desiccants are used when necessary to reduce the possibility of clumping under the high temperature and humidity conditions during sea transport.
