描述：

Oxygen-containing bleach particles are processed from sodium percarbonate, sodium carbonate and other washing ingredients. Usually, soaping agents mix sodium percarbonate with soda ash, sodium sulfate, sodium metasilicate, STPP and other products to form oxygen bleach, but this type of mixed product is usually unevenly distributed in the mixture because of their different densities, some even uniform, powdered products. This not only makes the appearance of the finished product unattractive, but also negatively affects its function.
