The products is white granule or fluffy powder with high purity and excellent fluidity. It is characterized as absorb moisture and promote flow. The product is used in various powdery foods to imporve fluidity of powder so as to prevent caking or to improve the diffusion ability of dry powder in liquid. Therefore, it can play a good role in anti-mildew.
