CHT’s organIQ BLEACH, a smart alternative to potassium permanganate (KMnO4) for denim fabric bleaching

organIQ BLEACH is an outstanding innovation of the CHT Group, that perfectly combines economic effectiveness, product safety, and environmental friendliness.

Bleaching jeans in an environmentally friendly way is always a challenge for denim manufacturers. The CHT Group has developed the organIQ BLEACH System as an alternative to potassium permanganate (KMnO4). organIQ BLEACH is the first patented purely organic bleaching agent for denim materials by which jeans bleaching becomes innovative. It is an effective and reproducible jeans treatment with advantages for the environment.


Why organIQ BLEACH

The organIQ BLEACH system is a completely biodegradable bleaching agent for denim. Potassium permanganate can be completely replaced in the spraying procedure. In case of an application with fog system, stonewash, and chlorine bleaches, all can be replaced with cold treatments, extremely low water consumption, and least wastewater pollution.

Advantages of organIQ BLEACH

A big ecological advantage of the organIQ BLEACH system is the good biodegradability of the bleaching agent in comparison to potassium permanganate (KMnO4).

  • The pure organic bleaching agent
  • Free from heavy metal, chlorine, and AOX
  • Completely biodegradable (> 99% in compliance with OECD 301B)
  • Without persistent components
  • No risk for the environment
  • No soiling of wastewater with heavy metals
  • No necessity of a where-used list according to valid legal requirements
  • No need of neutralization

Threats of potassium permanganate

The spray application with potassium permanganate (KMnO4) is the most used bleaching procedure worldwide, most reliable and proven bleaching procedures for denim fabrics but still, it is not that environment-friendly in many ways like-

  • Manganese is a heavy metal and non-biodegradable.
  • Potassium permanganate (KMnO4) belongs to the hazardous substances, which pose a great risk for the environment due to the high fish toxicity.
  • In many countries, there are strict regulations or even obligatory to take into account that any misuse of KMnO4 is avoided.
  • CMR classification for KMnO4 under evaluation at ECHA (European Chemical Agency). Reference: CLP Annex VI, No. 025:-022-00:-9

organIQ BLEACH spray application

The organIQ BLEACH system has three parts, main part is BLEACH T, BUFFER AO works as activator and organIQ ASSIST works as spray amount indicator.


organIQ BLEACH T alone in solution is water-clear, which is why organIQ ASSIST is added in spray application to make it visible. organIQ ASSIST has no affinity to fibers, so it can be easily rinsed out and also completely biodegradable (according to OECD 301B).

organIQ BLEACH + fog application

The combination of modern technologies such as organIQ + fog application leads to ecological washing results with maximum efficiency means protection of resources.

CHT organIQ BLEACH + fog application

These technologies are based on an extremely fine distribution of the product in the form of fog in the washing machine. A very homogeneous distribution and a very low liquor pick-up are obtained. This provides water and product saving process.

With the ecological and economical organIQ product range, CHT has developed the whole intelligent finishing system for denim and non-denim that is based on organic acids and does without heavy metals or chlorine.

The organIQ FAMILY includes organIQ BLEACH (patented), organIQ BIOPOWER (special enzyme for fog system) and organIQ NEUTRAL (applied for a patent).
