What makes it different?

Koh Sensitive Laundry Liquid is differentiated from conventional laundry detergents in five key ways. First, no added fragrance, so clothes come out clean rather than scented. Second, Dermatest tested with an excellent skin tolerability rating (renewed September 2025). Third, Sensitive Choice approved by the National Asthma Council Australia (renewed September 2025) for suitability with asthma and allergy sufferers. Fourth, ultra-concentrated at 60 washes per 1.5L bag-in-box, which uses around 80 percent less plastic than equivalent bottle packaging. Fifth, no chlorine bleach and no optical brighteners, the formula relies on enzyme-based stain breakdown rather than harsh oxidisers. The product is septic and grey water safe, made in Victoria, 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 down stains at the source rather than relying on harsh oxidisers like chlorine bleach. Enzymes are biological catalysts that target specific stain types, body oils and grease, sweat and protein residues, food and starch matter, and surface fibres on cotton fabrics. Because the formula breaks the stain down chemically rather than bleaching it out, it works effectively in cold water as well as hot, which saves energy on every wash. The enzyme-based approach is also gentler on fabric over time compared to chlorine-bleach-based formulas, which can weaken fibres with repeated washing. The formula contains no optical brighteners (the chemical whitening agents used by some detergents to make clothes appear brighter, which can build up on fabric over time and irritate skin), and no added fragrance.

✓ No harsh oxidisers

No chlorine bleach. No optical brighteners (the chemical whitening agents used by some detergents to make clothes appear brighter; they can build up on fabric over time and irritate sensitive skin). The enzyme approach is gentler on fabric across repeated washes than chlorine-bleach-based formulas, which can weaken fibres over time.


Who is it for?

Koh Sensitive Laundry Liquid is designed for households that want strong cleaning performance without added fragrance or harsh oxidisers. Specific audiences include 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 with septic or grey-water systems where formula choice affects waste-water safety. The product works in front loaders, top loaders, hot and cold cycles, and can be used for hand washing. Compatible with most cottons, synthetics, and blends. Not suitable for wool, silk, cashmere, alpaca, rayon/viscose, or linen, the enzymes can break down these animal-fibre and natural-fibre fabrics, hand-wash these with a wool-and-silk-specific detergent instead.
