How does Sensitive Laundry Liquid help clothes last longer?Updated 5 hours ago

TL;DR: Sensitive Laundry Liquid contains cellulase, an enzyme that gently breaks down loose surface fibres on cotton fabric. This reduces pilling and fuzz, keeps fabric smoother, and helps colours look brighter by clearing the dull surface layer that builds up over time. Result: 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. These loose fibres trap dirt, create a fuzzy or dull appearance, and eventually form pills (those small fabric balls that build up on heavily worn clothes). Cellulase gently breaks down these surface microfibres without affecting the structural integrity of the fabric. The result is smoother, brighter, longer-wearing cotton clothing. Cellulase is one of several enzymes in Koh Sensitive Laundry Liquid that work together for a thorough clean across different stain and fabric types.

✓ An enzyme for fabric care

Cellulase is an enzyme commonly used in modern laundry formulas to support fabric care, especially on cotton and other plant-fibre fabrics. During washing, tiny loose fibres lift from the surface of cotton fabric and create a dull or fuzzy look over time. Cellulase gently breaks down these surface microfibres without affecting the integrity of the fabric.

✓ How it helps your clothes

Reduces pilling (those small fabric balls that build up over time). Minimises fuzz and surface roughness. Maintains a smoother fabric feel. Helps colours look brighter by clearing the dull surface layer that builds up wash after wash.

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 actually breaks down. Pilling, fuzz, dullness, and faded surface colour are what makes clothing look old. By keeping the fabric surface smooth and clear, cellulase helps clothes look newer, fit better, and stay wearable for longer. Combined with the gentler wash environment of an enzyme-based detergent like Koh Sensitive Laundry Liquid (lower mechanical agitation needed, no harsh oxidisers), cotton clothing can hold its appearance through significantly more wash cycles. Note: Koh Sensitive Laundry Liquid is not suitable for wool, silk, cashmere, alpaca, rayon/viscose, or linen — the enzymes can break down these animal-fibre and natural-fibre fabrics.

✓ 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. That's why detergents with harsh formulas or aggressive mechanical action can shorten how long your clothes look good.

⚠ Not for wool, silk, or other animal fibres

The enzymes in Sensitive Laundry Liquid can break down protein-based fibres. Avoid using on wool, silk, cashmere, alpaca, rayon/viscose, and linen, hand-wash these fabrics with a wool-and-silk-specific detergent instead.
