Bathroom & Shower Cleaner is Sensitive Choice approved by the National Asthma Council Australia, Dermatest tested for skin compatibility, and recognised by the Eczema Association of Australasia. It is fragrance-free, pH 8, and contains no aerosol propellants, no chlorine bleach and no phosphates. Those three are the approvals it holds.

Is Bathroom & Shower Cleaner allergy, asthma and sensitive skin friendly?

For most sensitive households, yes. Bathroom and Shower Cleaner holds three relevant approvals. It is Sensitive Choice approved by the National Asthma Council Australia, a programme that reviews household products against criteria designed to reduce respiratory triggers. It is Dermatest tested for skin compatibility. And it is recognised by the Eczema Association of Australasia. The formula is fragrance-free, pH 8, and contains no aerosol propellants, no chlorine bleach and no phosphates. Those are the approvals it holds and the only ones Koh claims for it. It is not Allergy UK accredited. It is not a medical product and it is not a treatment for any condition, so if someone in the home has severe asthma, a diagnosed chemical sensitivity or a known ingredient allergy, check the full ingredient list against their triggers before first use and speak to a GP or specialist if you are unsure.

✓ Sensitive Choice approved

Approved by Sensitive Choice, the programme run by the National Asthma Council Australia, which reviews household products against criteria designed to reduce respiratory triggers. Approved products avoid aerosol propellants and strong fragrances.

Sensitive Choice No aerosol propellants

✓ Dermatest tested

Independently tested by Dermatest for skin compatibility. The pH 8 formula is milder than conventional bathroom cleaners, which are often strongly acidic or strongly alkaline. Vitamin E (tocopheryl acetate) is included as a skin-friendly ingredient.

Dermatest pH 8

✓ Eczema Association recognised

Recognised by the Eczema Association of Australasia. A considered pick for households managing eczema, dermatitis or ongoing skin sensitivities. Wear gloves for prolonged cleaning sessions and rinse any accidental skin contact with water.

⚠ What we don't claim

Sensitive Choice, Dermatest and the Eczema Association of Australasia are the approvals this product holds, and the only ones we claim for it. Bathroom & Shower Cleaner is not Allergy UK accredited. It is not a medical product and it is not a treatment for asthma, allergy or any skin condition. No cleaning product suits every person, so check the ingredient list against known triggers before first use.

Not Allergy UK accredited Not a medical product

What is in it, and what is left out?

Bathroom and Shower Cleaner is a twelve ingredient formula at pH 8, which is close to neutral and much milder than the strongly acidic or strongly alkaline bathroom cleaners it replaces. It is fragrance-free, so there is no added perfume to trigger a reaction, and any scent you want can be added yourself. It contains no aerosol propellants, no chlorine bleach, no phosphates and no benzalkonium chloride. Vitamin E, listed as tocopheryl acetate, is included as a skin-friendly ingredient. The full INCI list is published so you can check it against personal sensitivities before you buy.

How should I clean if someone in the home is sensitive?

A few simple habits reduce trigger exposure even when the product itself is a gentle one. Ventilate the bathroom during and after cleaning by opening a window or running the extractor fan. Wear rubber or nitrile gloves to limit skin contact during prolonged cleaning. Clean while the affected person is out of the room. Rinse surfaces thoroughly and let them dry fully before anyone showers. For severe asthma or multiple chemical sensitivities, discuss specific products with a GP or allergy specialist before introducing them to the home.

✓ Habits that reduce exposure

1

Ventilate during and after. Open a window or run the extractor fan. Moving air keeps airborne droplets from lingering.

2

Wear gloves. Rubber or nitrile for prolonged cleaning. Rinse any accidental skin contact with water.

3

Clean while they are out of the room. Even with a gentle product, removing the person from the environment is the safest step.

4

Rinse and dry. Rinse thoroughly and let surfaces dry fully before anyone showers.
