Characteristics
Appearance: Pale yellow, transparent liquid
pH (10% aqueous solution): 7–9
Solubility: Miscible with water in any proportion.
Compatibility: Avoid contact with or simultaneous use of any reducing agents, ammonia solution, bleach, acids, or alkalis.


Reference Process
Use in combination with the high-manganese substitute R-PP.


Precautions

Considering fabric type and processing techniques, it is always recommended to conduct small-scale trials before full-scale production to verify in advance the likelihood of achieving the desired final results.
The bleaching working solution should be prepared fresh and used immediately; once prepared, it must be used within 12 hours. After 12 hours, the bleaching performance of the solution will gradually decline, compromising the bleaching effect and leading to variations in color removal across different production batches.
Given that the working solution does not penetrate the fabric as deeply as potassium permanganate, it is recommended to use a brush to apply the solution evenly after spraying.
Certain plastic boxes and metal containers (or their accessories) are sensitive to the product or processing temperature. Whenever possible, use only high-density polyethylene or stainless steel containers, or at least verify their stability in advance.
