ACCELATOR POWDER 1. Chemistry: In chemical processes, an accelerator powder could refer to a substance used to speed up the rate of a chemical reaction. For example, in certain types of chemical reactions like polymerization or curing of resins, accelerator powders are added to increase the reaction rate. These powders typically contain compounds that act as catalysts or promoters for the reaction. 2. Cosmetics (Hair Products): In the context of hair treatments, particularly hair color or bleaching, an accelerator powder might be used to hasten the development or processing time of the product. For instance, in hair bleach, an accelerator powder could be added to the bleach mixture to speed up the lightening process of the hair.
