This product loves water and when exposed to humidity will start to clump quickly. We pack in sealed plastic containers but you may see clumping has occurred when you open the container. This is normal and should not cause a problem. We assume that most end uses will include a water component of one sort or another. If this does not suit your needs then please do not buy this product.
