The Deosan Story
Deosan has been helping New Zealand dairy farmers since the 1990s - starting with TEATX, a post-milking teat spray that set the benchmark for teat care. Since then, we’ve expanded into detergents and animal health while keeping our focus the same: make it simple, effective, and backed by science.
Today, we’re still family-owned, proudly New Zealand made, and committed to helping farmers protect their herds and produce quality milk.
