Can I use Dishwashing Liquid as hand soap?Updated a day ago

No. Koh Dishwashing Liquid is formulated to lift food residue and grease off plates and to rinse away cleanly, and a hand wash is formulated for repeated contact with skin. Those are two different jobs and each product is built for its own. Skin contact while you are washing up is expected and accounted for in the formula, which is pH 6.5, carries glycerin as a humectant for hand-feel, and is Dermatest tested for skin tolerance. For washing hands, use Koh Hand Wash, which is made in Australia and formulated for that job.

That is expected and accounted for. Koh Dishwashing Liquid is Dermatest tested for skin tolerance, Eczema Association of Australasia recognised and Sensitive Choice approved by the National Asthma Council Australia. The formula sits at pH 6.5 and carries glycerin as a humectant, which is there specifically because washing up is a bare-handed job. People vary, though, and Koh does not claim a wholesale 100 per cent for every pair of hands. In general it is a gentler choice than a perfumed detergent, and the substantiation is the testing above plus a fragrance-free, dye-free, 11-ingredient formula. If your hands are already broken or irritated, wear gloves and speak to a pharmacist or GP.

Most of the drying at a kitchen sink comes from hot water and time in it rather than from the detergent. Use comfortably warm water rather than the hottest you can stand, let the 5 to 10 minute soak do the work instead of scrubbing, and dry your hands properly afterwards. Koh Dishwashing Liquid carries glycerin as a humectant for exactly this reason. If you wash up several times a day, gloves and a hand cream afterwards make more difference than changing detergent.
