What makes it different?

Koh Sensitive Laundry Liquid differs from conventional laundry detergents in five ways. There is no added fragrance, so clothes come out clean rather than scented. It is Dermatest tested. It is Sensitive Choice approved by the National Asthma Council Australia for suitability with asthma and allergy sufferers, and Good Environmental Choice Australia (GECA) certified. It is ultra-concentrated, giving around 60 washes from one bag-in-box, which uses 80 to 90 per cent less plastic than a rigid container of the same volume. And it contains no chlorine bleach and no optical brighteners, because stain removal comes from an enzyme system instead. It is septic compatible when used as directed, made in Australia, and works in front loaders, top loaders, hot and cold cycles, and for hand washing.

How does it clean?

Koh Sensitive Laundry Liquid uses a targeted enzyme system to break stains down at the source rather than bleaching them out with chlorine. Enzymes are biological catalysts, and each one works on a specific stain type: body oils and grease, sweat and protein residues, food and starch matter, and surface fibres on cotton. Because the stain is broken down chemically rather than bleached, the formula works in cold water as well as hot, which saves energy on every wash. The formula contains no optical brighteners and no added fragrance.

✓ Enzyme-based stain breakdown

A targeted enzyme system breaks down body oils, sweat residues, food matter and other organic stains at the source. Because enzymes work chemically rather than by bleaching, the formula is effective in cold water as well as hot, which saves energy on every wash.

Body oils Sweat residues Food matter Cold-water effective

✓ No chlorine bleach, no optical brighteners

Optical brighteners are the whitening agents some detergents use to make fabric look brighter than it is. Sensitive Laundry Liquid leaves them out, and leaves out chlorine bleach too. Stain removal comes from the enzyme system instead, so the wash stays gentle on fabric across repeated cycles.


Who is it for?

Koh Sensitive Laundry Liquid is built for households that want strong cleaning without added fragrance or chlorine bleach. That includes people with sensitive skin who react to perfumed detergents, asthma and allergy households where fragranced products can trigger symptoms, families washing baby and kids' clothes, anyone who prefers a neutral wash, and homes on a septic system. It works in front loaders, top loaders, hot and cold cycles, and for hand washing, and suits most cottons, synthetics and blends. Wool, silk, cashmere and alpaca need a wool-and-silk-specific detergent instead, because the enzymes can break down protein fibres.

✓ Sensitive skin and allergies

For people who react to perfumed detergents, optical brighteners or chlorine-based formulas. Sensitive Choice approved and Dermatest tested.

✓ Families and kids' clothes

For washing baby clothes, kids' uniforms and everyday family laundry where you want effective cleaning without added fragrance.

✓ All machines and methods

Front loaders, top loaders, hot and cold cycles, and hand washing. Suitable for most cottons, synthetics and blends.

⚠ Wool, silk and other protein fibres

The enzymes can break down protein fibres, so wash wool, silk, cashmere and alpaca by hand with a wool-and-silk-specific detergent instead.
