What wash temperature works with Sensitive Laundry Liquid?Updated 20 hours ago

TL;DR: Sensitive Laundry Liquid works across all common wash temperatures. Cold and warm cycles (10-40°C) get the best enzyme performance. Hot cycles up to 90°C still clean (surfactants do most of the work at high heat) but enzymes become less effective above 50°C. Always follow garment care labels.

Which wash temperatures work?

Koh Sensitive Laundry Liquid is compatible with all common wash temperatures from cold through to 90°C. The formula combines enzymes (biological catalysts that break down specific stain types) and surfactants (cleaning agents that lift dirt and oils). Enzymes work best in cool to warm water (10-40°C), which covers cold, eco, and warm cycles on most machines. Above about 50°C they progressively denature and stop working, so on hot cycles the surfactants do most of the cleaning. Cold cycles are great for everyday loads and energy savings. Warm cycles (30-40°C) get the best enzyme performance on protein and oil stains like sweat, food, and body oils. Hot cycles (60-90°C) are best reserved for hygiene loads like towels, bedding, or items that genuinely need sanitising, where the heat itself is doing the work. Always follow the garment care label first, especially for delicates that may need cool water regardless of the detergent.

✓ Cold (10-25°C)

Great for everyday loads and saving energy. Enzymes work well in cold water, just slightly slower than warm.

Everyday loads Energy saving

✓ Warm (30-40°C)

Best enzyme performance. Ideal for mixed loads and stained clothing, sweat, food, body oils.

Mixed loads Stained items

✓ Hot (60-90°C)

Compatible but enzymes denature above 50°C. Best reserved for hygiene loads where heat is doing the work, towels, bedding, sanitising.

Towels and bedding Hygiene loads

✓ Good to know

  Always follow your garment care label for temperature guidance

  Hot water can set protein stains (sweat, blood, food), use cool or warm for those

  For delicates, use the lowest safe temperature on the care label

  Warm cycles get the most out of the enzyme system for everyday wash loads
