Can I use Sensitive Laundry Liquid for both whites and colours?Updated 7 hours ago

TL;DR: Yes. Sensitive Laundry Liquid handles whites, colours, and mixed loads with the same formula. No chlorine bleach to fade colours. Anti-redeposition surfactants stop whites greying. ⚠ Not for wool, silk, or other animal fibres.

Is it safe for whites and colours?

Yes. Koh Sensitive Laundry Liquid is designed to work on both white and coloured laundry, including mixed loads. The formula contains no chlorine bleach (which can weaken fibres and fade colours over repeated washes) and no optical brighteners (chemical agents that make whites look brighter under UV light without actually cleaning). Surfactants in the formula keep wash-water soils suspended so they rinse away rather than redepositing on whites and causing greying. Colours are protected because there's no aggressive oxidiser stripping the dye. Use the same dose (24ml or 6 pumps for a regular load, 40ml or 10 pumps for a large or heavily soiled load) on either type of wash. For best colour retention separate heavily dyed items, especially new dark items, on their first few washes if you're worried about colour transfer. Not for wool, silk, cashmere, alpaca, mohair, or angora, the enzymes can break down protein-based fibres regardless of colour.

✓ One formula for both

Sensitive Laundry Liquid works on whites, colours, and mixed loads with the same dose. Use 24ml (6 pumps) for a regular load, or 40ml (10 pumps) for a large or heavily soiled load.

Whites Colours Mixed loads

✓ How it protects fabric

  Anti-redeposition surfactants stop whites greying

  No chlorine bleach to weaken fibres or fade colours

  No optical brighteners faking it under UV light


⚠ Not for wool, silk, or other animal fibres

The enzymes in Sensitive Laundry Liquid can break down protein-based fibres regardless of colour. Avoid wool, silk, cashmere, alpaca, mohair, and angora. Hand-wash these with a wool-and-silk-specific detergent instead.

✓ Tips for mixed loads

  Always follow the garment care label

  Wash new dark items separately for the first few washes (most dye loss happens early)

  Use cool or warm water for best enzyme performance, hot water can set protein stains and reduce enzyme effectiveness
