Potassium permanganate replacement: PPR is used for partial replacement of potassium permanganate for local treatment of denim garments.

1. Potassium permanganate replacement:PPR
Brief information
A highly effective decolorizing agent based on a metal complex-like enzyme catalyst oxidation system,
which does not contain heavy metals, halogens, formaldehyde and banned surfactants, and is used for partial
replacement of potassium permanganate for local treatment of denim garments.
Properties and fields of application
1. PPR contains no toxic substances such as manganese compounds, chlorine, bromine, iodine,
formaldehyde, APEO, etc., which makes the products have lower risk and minimal environmental impact.
2. PPR is a ready-to-use product, which can be used to obtain a partial decolorization effect on denim
garments. The decolorization effect is more natural and has a perfect nostalgic effect.
3. PPR is suitable for all kinds of fabrics, whether it contains elastic yarn, whether it is indigo or
vulcanized, it has excellent decolorization effect.
4. PPR is simple to use and safe to operate, and can be used as potassium permanganate without
additional steps and baking.
General properties
Appearance yellow translucent liquid
pH (10% aqueous solution) 0.8-3.0
Solubility soluble in water
Compatibility
Avoid contact with any reducing agent,
ammonia, chlorine compound or alkali
Environmentally friendly
free of heavy metals, halogens,
formaldehyde, APEO AOX, etc.
Application
1. PPR is mainly used for desizing a clean denim fabric, which must be rubbed before spraying. It is not
recommended for raw spray. If you want to spray, please test it first, and you must first wipe the fabric and

2. then spray it.
2. PPR is usually sprayed locally with a spray gun. Depending on the desired effect and factory
conditions, tools such as sponges, brushes and gloves, or soaking methods can be used to achieve different
treatment goals.
3. After the PPR is applied to the garment, place the garment at room temperature for at least 15
minutes to allow the product to react gently and completely without drying to accelerate the reaction.
4. Before the subsequent washing, please strictly and correctly neutralize according to the following
process:
a) Treat with 2~3 g/L sodium metabisulfite at 50 °C for 10 minutes.
b) over water
c) Treat with 2~3 g/L sodium carbonate + 3~5 g/L hydrogen peroxide at 50 °C for 10 minutes.
This guarantees excellent whiteness and long-lasting uniformity. When the fabric is heavily colored, it
is recommended to add a suitable anti-staining agent in the above 2 steps and in the process.
Dosage
PPR can be used directly, using the same method as traditional potassium permanganate.
It is easy to see the effect with a spray gun. The specific amount varies depending on the desired effect
and the fabric. Normally, a piece of clothing is 30~80 g.
If you need a heavier effect, you can use microfiber gloves for local treatment.
Notes
1. Considering the type of fabric and the process used, it is always advisable to conduct a small test
before the bulk application to verify the possibility of achieving the final desired result in advance.
Excessive exposure or exposure to high temperatures can affect the discoloration of the product or accelerate
its reaction, and may also cause damage to the strength and elasticity of the fabric.
2. After the fabric is sprayed with the working fluid, keep the clothes at room temperature and let it dry
naturally. Do not dry the fabric at high temperature. Neutralization can only be carried out after the fabric
has been dried to a degree of 7 to 80%. Please pay special attention to the fact that after spraying the
working fluid, the fabric should not be placed for more than 4 hours before neutralization. We always
recommend considering the type and application of the fabric and assessing the most suitable conditions in
advance.
3. PPR is not as permeable to fabric as potassium permanganate. After spraying the working fluid, it is
recommended to apply the working fluid evenly with a brush.
4. Some plastic box metal containers (or aids) are sensitive to the product. If possible, use only high
density polyethylene or stainless steel containers, or check stability at least in advance.
Packaging and storage
60 kg or 125 kg plastic drum. Store at room temperature, avoid direct sunlight, and avoid any reductive
contact and remain stable for at least 6 months.
