How does Sensitive Laundry Liquid help extend the life of clothes?Updated 7 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?
✓ 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. 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?
✓ 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.
⚠ 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, and alpaca, hand-wash these fabrics with a wool-and-silk-specific detergent instead.
Around 60 washes per box. Sensitive Choice approved, Dermatest tested. Septic and greywater safe.
