What wash temperature works with Sensitive Laundry Liquid?

Koh Sensitive Laundry Liquid works from cold through to 90 degrees. The enzymes do their best work between 10 and 40 degrees, which covers cold, eco and warm cycles on most machines. Above about 50 degrees they stop working and the surfactants do the cleaning instead. Follow the garment care label first, especially for delicates.

✓ Cold, 10 to 25 degrees

Good for everyday loads and for the power bill. The enzymes work well in cold water, just a little slower than in warm.

Everyday loads Energy saving

✓ Warm, 30 to 40 degrees

The best of the enzyme system. Suits mixed loads and marked clothing, so sweat, food and body oils.

Mixed loads Marked items

✓ Hot, 60 to 90 degrees

Works, though the enzymes stop above about 50 degrees. Keep hot cycles for hygiene loads like towels and bedding, where the heat is doing the work.

Why does temperature matter for the enzymes?

Enzymes are biological catalysts that break down specific kinds of mark, and they have a working temperature range of roughly 10 to 40 degrees. Above about 50 degrees they stop working, so on a hot cycle the surfactants in Koh Sensitive Laundry Liquid do the cleaning instead. Hot water can also set protein marks like sweat, blood and food, so use cool or warm for those.

Enzymes are biological catalysts that break down specific kinds of mark, and they have a working temperature range of roughly 10 to 40 degrees. Above about 50 degrees they stop working, so on a hot cycle the surfactants in Sensitive Laundry Liquid do the cleaning instead. That is why a warm wash often gets more out of the box than a hot one.
