White stains are divided into 2 types. Type 1 is caused by the action of Active ingredients that create a change in the formation of white stains. But it will be a stain that looks liquid, not viscous. Type 2 is stains caused by incompatibility of
สารสร้างเนื้อเจล , which may be due to Spinning too fast and taking too little time Which the stains will look viscous, white, tight from the mixture, if the white stains are so large Probably from mixing HEC more. Probably caused by too much viscosity. or the temperature does not reach the melting point or spinning in a cycle that is too fast and too strong or spinning in too little time or spinning in too much time This amount of other active ingredients does not contribute to the formation of a large white cast.
