How does Sensitive Laundry Liquid help clothes last longer?Updated 11 days ago

TL;DR: Sensitive Laundry Liquid contains cellulase, an enzyme that gently breaks down loose surface fibres on cotton fabric. That reduces pilling and fuzz, keeps fabric smoother, and helps colours look brighter by clearing the dull surface layer that builds up over time. Clothes look newer for longer.

What is cellulase?

Cellulase is an enzyme commonly used in modern laundry formulas to support fabric care. It targets cellulose, the structural carbohydrate found in cotton and other plant-fibre fabrics. During washing and wear, tiny loose fibres lift from the surface of cotton fabric over time. Those loose fibres trap dirt, create a fuzzy or dull appearance, and eventually form pills, the small fabric balls that build up on heavily worn clothes. Cellulase gently breaks down those loose surface fibres without affecting the structural integrity of the fabric, so cotton clothing stays smoother and brighter. Cellulase is one of several enzymes in Koh Sensitive Laundry Liquid that work together across different stain and fabric types.

Why does it matter for your wardrobe?

Most clothes don't fail because the fabric wears through. They look worn out long before the fabric breaks down. Pilling, fuzz, dullness and faded surface colour are what make clothing look old. By keeping the fabric surface smooth and clear, cellulase helps clothes look newer, fit better and stay wearable for longer. Koh Sensitive Laundry Liquid works through enzymes rather than chlorine bleach, so cotton clothing holds its appearance across more wash cycles. Wool, silk, cashmere and alpaca need a wool-and-silk-specific detergent instead, because the enzymes can break down protein fibres.

✓ Clothes stay wearable for longer

Most cotton clothing doesn't fail because the fabric wears through, it just looks tired. Pilling, fuzz, surface dullness and faded colours are what make clothing look old. By keeping the fabric surface smooth and clear, cellulase helps clothes look newer, fit better and stay wearable for longer.

⚠ Wool, silk and other protein fibres

The enzymes in Sensitive Laundry Liquid can break down protein fibres, so wash wool, silk, cashmere and alpaca by hand with a wool-and-silk-specific detergent instead.
