There is a potential that during the coldest climates and coldest months of the year certain products may freeze during shipment. As it warms the product returns to its original state. Performance and function is not affected. This is an expected and planned for phenomenon. As a result it is generally standard operating procedure to conduct freeze/thaw tests as part of a product stability analyses before it is brought to market. You may at times see particles which are generally oils, waxes, flavors etc. that have solidified which are the last to reacclimatize themselves into the formula. Please allow product to warm at room temperature and shake vigorously to help the small solids liquify back into the formula. If you experience any issues in this phenomenon, please feel free to reach out to customer service for replacement and/or resolution options.
