In the fast-evolving world of washing chemicals and textile enzymes, innovation drives efficiency, sustainability, and quality. Stonezyme SF, developed by KDN Biotech (Shanghai) Co., Ltd., represents a breakthrough in neutral cellulase enzyme technology. Engineered for fast abrasion, high contrast, and low staining, it delivers outstanding results in denim washing—while significantly reducing or even eliminating the need for pumice stones.

Advanced Enzymatic Technology

Stonezyme SF is formulated with a new generation of neutral cellulases, enhanced buffer chemicals, and anti-stain agents. This unique combination ensures balanced performance—providing excellent abrasion, acceptable grain, and minimal back-staining, even under mild washing conditions.

Key Features and Benefits

• Superior abrasion performance with a highly competitive cost-performance ratio.

• Wide temperature range (30–60°C) — performs effectively under various process conditions.

• Neutral pH adaptability (5.5–8.0) — compatible with most washing systems.

• Stone-free or stone-reduced processing — minimizes pumice stone usage, reducing machine wear and environmental impact.

• Optimal operation at 45–55°C — achieves the perfect balance between graining, color contrast, and low staining.

By integrating Stonezyme SF into denim finishing, manufacturers can reduce energy use, simplify processes, and produce high-quality, environmentally friendly garments.

Application Guidelines

Recommended Dosage:

• Denim garments (belly washers/front loaders): 0.5–1.0% owg

Recommended Conditions:

• Temperature: 30–60°C (optimal: 45–55°C)

• pH range: 5.5–8.0 (optimal: 6.0–7.0)

These flexible conditions make Stonezyme SF an ideal choice for laundries aiming to optimize performance and reduce production costs while maintaining consistent wash effects.

Sustainability and Versatility

Unlike conventional washing chemicals, Stonezyme SF relies on biodegradable enzyme technology. Its ability to function efficiently at low to moderate temperatures contributes to energy savings and environmental sustainability.

While primarily designed for denim finishing, its formulation technology is part of KDN Biotech’s broader enzyme portfolio, which also includes food enzymes and detergent enzymes—all engineered for cleaner, greener manufacturing solutions.

Packaging and Storage

• Packaging: 25 kg paper box

• Storage: Keep at or below 25°C in a sealed container to maintain enzyme activity. Avoid exposure to heat for prolonged periods.

Safety and Handling

Stonezyme SF is non-flammable and safe when handled properly. Avoid inhalation of enzyme dust or mist. In case of skin or eye contact, rinse immediately with plenty of water for at least 15 minutes. For detailed handling procedures, consult the Material Safety Data Sheet (MSDS) available from KDN Biotech (Shanghai) Co., Ltd.

Conclusion

Stonezyme SF combines the latest advancements in neutral cellulase enzyme technology with superior process efficiency. Its wide operating range, cost-effectiveness, and eco-friendly formulation make it a preferred choice in modern textile enzyme applications. By using Stonezyme SF, garment processors can achieve premium denim aesthetics—with less energy, less waste, and more value.
