When using hydroxypropyl methylcellulose, it is necessary to pay attention to adding the appropriate amount of water and how to stir the formulated product, and how to obtain the final mixture. Take the required amount of hot water, put it in a container and heat it to more than 85, gradually add this product under slow stirring, the cellulose initially floats on the surface of the water, but is gradually dispersed by the water, forming a uniform slurry, under stirring Cool until transparent. Or heat 1/3-2/3 water above 85, add cellulose to obtain hot water slurry, then add the remaining amount of cold water, keep stirring, and cool to about 20 to obtain the mixture.
