Catalase, Liquid


Terminox® is a family of bleach clean-up solutions available in a range of concentrations. Terminox® products contain a unique catalase that removes even the smallest traces of bleach. That leaves textiles ready for consistent, even batch-to-batch dyeing reproducibility.

Key Benefits Description Safe handling
  • Safe dyeing

    Cleaning up bleach with water alone leads to a risk of residual hydrogen peroxide affecting the color shade. With sodium thiosulphate, there's a risk of residual reducing agent affecting shade and evenness. This product helps your mill avoid these risks and achieve the desired shade and even dyeing.  

  • Batch-to-batch reproducibility

    Terminox® products prepare textiles for consistent dyeing results. That helps you avoid patches/uneven color. The result is final products with better overall color, as well as batch-to-batch reproducibility.

  • Saves water, energy and time

    Traditional bleach clean-up processes with water or reducing agent use large amounts of water for rinsing. They also use lots of energy for heating and pumping the water. Depending on your process, Terminox® products could save you up to 30 minutes and between one and three water baths. That leads to energy savings.

  • Higher production throughput

    Terminox® products eliminate the need for further rinses before dyeing. That can allow you to more than halve your process time. With process times as low as 20-30 minutes, you can achieve higher production throughput.

  • Flexible implementation

    Enzymatic bleach clean-up with Terminox® products can be a stand-alone process. Using our patented CombiPolish® process, it can also take place together with biopolishing in the dye bath. Terminox® products are robust enough to work across a variety of temperature and pH ranges, so they can be implemented in most processes.

  • Reduces effluent output or load

    A conventional approach to bleach clean up is rinsing with vast amounts of water. Terminox® products ensure consistent bleach clean-up with far less water. The result is savings of 20,000 liters of water per ton of textile and reduced effluent output for your mill. Another approach to bleach clean up is reducing agents. These increase Total Dissolvable Solids (TDS) loads in your effluent. With Terminox® products, you can reduce these loads. 

  • A more sustainable solution

    This product is both biodegradable and renewable. In many processes it saves water and energy. That makes it a more sustainable solution.

Terminox® products ensure consistent bleach clean-up. They also use far less water and energy than conventional methods. These include reducing agents, or rinsing with vast amounts of water. 

This product contains enzymes. While enzymes are safe to use in consumer applications, they need correct handling in working environments to ensure workers’ safety.

Indeed, repeated inhalation of enzyme dust or aerosols resulting from improper handling may induce sensitization and may cause allergic type 1 reactions in sensitized individuals.


Please follow the precautionary handling recommendations below:

  • Avoid breathing dust/fume/gas/mist/vapors/spray
  • Avoid contact with eyes, skin, or clothing
  • In case of inadequate ventilation wear respiratory protection
  • IF INHALED: Remove person to fresh air and keep comfortable for breathing
  • If experiencing respiratory symptoms: Call a POISON CENTER or a doctor
  • Store in a dry place. Store in a closed container
  • Dispose of contents/containers in accordance with local regulations

How catalases work in bleach clean-up

Residual bleach in fabric can prevent dyeing reproducibility. Catalases split hydrogen peroxide into water and oxygen. That makes them a fast, cost-effective alternative to water or reducing agents.  

For consistent batch-to-batch dyeing reproducibility, each batch needs the same starting point. Textile mills achieve this by bleaching the fabric with hydrogen peroxide (H2O2) in advance. But any residual bleach will impact dyeing reproducibility. So it's just as important to 'clean up' all residual hydrogen peroxide in a bleach clean-up process.

Conventional methods of bleach clean-up include reducing agents or rinsing with vast amounts of water. Both methods can leave residual bleach or reducing agents such as sodium thiosulphate in the fabric. These will affect dyeing consistency.

Catalases simply split H2O2 into water (H2O) and oxygen (O2). That means there's no need for reducing agents or further rinses. Enzymes are also highly specific in their action, so any residual catalase won't affect the dyeing process or fabric.
