Do you test on animals?Updated 11 hours ago
TL;DR: No. Neither our finished products nor their ingredients are tested on animals by Koh at any stage of development. We work only with suppliers who give assurance that the raw materials we buy are not tested on animals for Koh's use. Our formulations are developed using well-established non-animal testing methods and existing safety data for each ingredient.
✓ Finished products and ingredients
The policy covers both. It is not limited to the finished bottle, and it applies at every stage of development.
✓ Suppliers too
We work only with suppliers who give assurance that the raw materials we buy are not tested on animals for Koh's use.
Do you test on animals?
✓ No, we do not test on animals
Neither our finished products nor their ingredients are tested on animals by Koh at any stage of development. We work only with suppliers who provide assurance that the raw materials we purchase are not tested on animals for Koh's use.
This applies across the products we sell in the UK, not to one item in the range.
How do you know the products are safe, then?
✓ Non-animal test methods
Formulations are developed using well-established, non-animal testing methods and existing safety data for each ingredient.
✓ Short ingredient lists
Fewer ingredients means fewer unknowns. Universal Cleaner, for example, is a highly diluted inorganic ingredient and purified water.
Some products are also independently assessed by third parties for skin tolerability or allergy suitability. Those are separate schemes with their own criteria, and they are held product by product rather than across the range.
Does not tested on animals mean the products are vegan?
⚠ Two different claims, often confused
Not tested on animals is about testing and applies across the products we sell. Vegan is about ingredients and has to be confirmed for each product individually.
Universal Cleaner contains no animal-derived ingredients and is suitable for vegans. We will not stretch that statement across the range, so ask us if you need the position on a specific product.
Testing is not the same as ingredients
The ingredients side of the question, and why we keep vegan and cruelty-free as separate claims.
