Does Sensitive Laundry Liquid contain fabric softener?Updated 8 hours ago

TL;DR: There's no traditional fabric softener in Sensitive Laundry Liquid. It's formulated with cellulase, an enzyme that helps natural fibres keep their as-new feel and stay softer for longer, so plenty of people find they don't need a separate softener. You can still add one if you'd like to.

Does Sensitive Laundry Liquid contain fabric softener?

There is no traditional fabric softener in Koh Sensitive Laundry Liquid. It is formulated with cellulase, an enzyme that helps natural fibres keep their as-new feel and stay softer for longer, so plenty of people find they do not need a separate softener. You can still add one if you would like to.

✓ What's in there instead

A conventional softener works by leaving a conditioning agent sitting on the fibres. Sensitive Laundry Liquid takes a different route. Cellulase, one of the enzymes in the formula, works on the tiny loose fibres that build up on natural fibres wash after wash, which is what helps cotton keep its as-new feel and stay softer for longer.

✓ No added fragrance either

A lot of what people associate with softener is the scent rather than the feel. There's no added fragrance in Sensitive Laundry Liquid, and no dyes or optical brighteners. It's Sensitive Choice approved and Dermatest tested, which is why sensitive households tend to land on it.

Do I still need a separate fabric softener?

It comes down to preference. Plenty of people find Koh Sensitive Laundry Liquid is enough on its own for everyday cottons and synthetics. If you prefer the feel or scent of a dedicated softener, add one in your machine's softener compartment so it releases at the rinse, and follow the softener maker's dose.

✓ It's optional, and here's how to add one

1

Dose Sensitive Laundry Liquid into the main detergent drawer, or straight into the drum before you load. A normal load of 3 to 6 kg takes 24 mL, which is 6 full pumps of the Laundry Pump or the 24 mL marker on the Laundry Dosing Cup.

2

Put the softener in the softener compartment, usually marked with a flower or a star. Your machine holds it back and releases it during the rinse, which is where softener is meant to act.

3

Follow the softener manufacturer's dose. It's their product, so their instructions apply.

Keeping the two in separate compartments is just how the machine is designed to run. It's the same advice you'd get for any detergent.


Are there loads where softener is a bad idea?

Fabric softener is not recommended on some loads whatever detergent you use. Softener residue reduces towel absorbency over time, it clogs the wicking structure in activewear, and it can interfere with the treatment on fire-retardant children's sleepwear. Always follow the garment care label.

⚠ Three loads to leave softener out of

1

Towels. Softener residue builds up on the loops and reduces how much water a towel takes up. Skip it and towels stay thirsty.

2

Activewear and moisture-wicking fabrics. Softener sits in the wicking structure that moves sweat away from the skin, which is the one thing those fabrics are built to do.

3

Fire-retardant children's sleepwear. Softener can interfere with the flame-retardant treatment, so leave it out entirely on those items.

This applies to any detergent, not just ours. The garment care label has the final say, so follow it where it differs.
