Koh

Koh is an Australian brand of household cleaning products founded in 2016, born from a simple yet radical question: why do household cleaners need to contain harsh chemicals? The answer was a reimagined cleaning system from the ground up, developed in collaboration with researchers from UNSW Sydney. The key active ingredient — scientifically purified water and a trace of potassium hydroxide, the same compound that forms the basis of traditional liquid soap — allows for effective results on multiple surfaces without resorting to VOCs, phthalates, or other problematic synthetic substances. All products are eco-certified, cruelty-free, and designed with a waste reduction logic: refillable and reusable containers, made to last over time rather than being continuously replaced. Today, Koh is present in over two million homes and has established itself as a leading brand for sustainable cleaning on the international stage.

The Koh selection on OneBioShop

The 14 Koh items available in the catalog cover the entire cycle of household cleaning: from universal surface care to bathroom and kitchen cleaners, from laundry products to dishwashing, and even reusable accessories like technical cloths, brushes, and spray bottles. The recommended starting point is the universal cleaner, designed to replace over twenty conventional products on floors, glass, fabrics, and countertops. Those facing specific situations — stubborn stains, intense degreasing, care for delicate fabrics — will find dedicated formulations that follow the same philosophy: absence of harsh fragrances, compatibility with environments frequented by children and pets, and refillable formats to reduce single-use plastic. The entire range carries the same eco-certifications, making the choice simple regardless of the initial need.
