Eco-Friendly Catalase Solution for Post-Bleaching and Dyeing Preparation

Catazyme 800L, developed by KDN Biotech (Shanghai) Co., Ltd., is a highly concentrated industrial-grade liquid catalase enzyme produced by submerged fermentation of a genetically modified Bacillus subtilis strain. It is specially designed to decompose residual hydrogen peroxide left after the bleaching of cotton knits and yarns — ensuring clean, safe, and dye-ready fabrics.

By breaking down hydrogen peroxide into oxygen and water (2H₂O₂ → 2H₂O + O₂), Catazyme 800L provides an eco-friendly and efficient solution that minimizes water use, reduces processing time, and protects fabric quality before dyeing.

Typical Characteristics

Activity Definition:
1 Ctun = the amount of enzyme that decomposes 1 μmol of hydrogen peroxide per minute under standard test conditions (pH 7.0, 30°C).

Key Advantages

• Efficient Hydrogen Peroxide Removal – Ensures complete peroxide breakdown before dyeing.
• Reduced Water Consumption – Allows processing in the same bath, saving rinse water.
• Short Process Time – Rapid peroxide elimination for faster production cycles.
• Safe and Reliable – Prevents dyeing defects caused by peroxide residues.
• Eco-Friendly – Converts peroxide into harmless oxygen and water, reducing wastewater load.

Application Guidelines

1. Drain the bleaching liquor bath.
2. Refill with fresh water at the temperature and liquor ratio required for dyeing.
3. Adjust bath pH to 6–8 and ensure temperature is below 55°C.
4. Add 0.002–0.005 g/L Catazyme 800L and begin circulation.
5. After 10 minutes, test for residual hydrogen peroxide. If present, continue for another 5–10 minutes.
6. Once peroxide elimination is confirmed, proceed directly to the dyeing process in the same bath.

Dosage Recommendations

• Typical range: 0.001–0.01 g/L (depending on fabric type and residual peroxide level)

• Best results: Maintain optimal temperature below 55°C and neutral pH.

Packaging & Storage

• Packaging: 30 kg plastic drum

• Storage: Keep sealed at or below 25°C

• Shelf life: 12 months under good storage conditions

Safety & Handling

Avoid inhaling enzyme mist or dust. In case of skin or eye contact, rinse thoroughly with water for at least 15 minutes.
Refer to the Material Safety Data Sheet (MSDS) available from KDN Biotech (Shanghai) Co., Ltd.

Sustainable Processing with Catazyme 800L

Hydrogen peroxide is a key agent in textile bleaching, but its residues can interfere with dye uptake and fabric quality. Catazyme 800L offers a green, high-performance alternative to chemical neutralizers, ensuring peroxide-free fabrics ready for dyeing.

Its enzymatic process not only safeguards fiber integrity but also enhances process safety, reduces water use, and minimizes environmental impact, making it an ideal choice for modern textile mills and garment laundries committed to sustainability and operational excellence.
