Built on TEATX,
Grown with Farmers
Deosan began in the 1990s with a simple but powerful idea: protect herd health with products that actually work in New Zealand conditions. The first step was TEATX, a post-milking teat spray that quickly became the gold standard for udder health across the country.
That one product built our foundation - and it’s still trusted today. From there, we expanded into detergents and mineral supplements, always guided by the same principle: keep it effective, keep it simple, and keep it science-backed.
Kiwi-Made,
Science-Backed
We’re proud to formulate and manufacture right here in New Zealand. Our products are designed for the way Kiwi farmers work, and tested in the same sheds they’ll be used in.
Behind every drum is years of research, practical trials, and feedback from farmers who know what works. That balance of science and real-world testing is what makes Deosan products reliable - from teat care to shed hygiene and herd nutrition.
A Team on the Ground
What makes us different isn’t just the products, it’s the people.
We’ve built a nationwide team of Territory Managers who are part of the farming community, not just names on a label.
Whether you’re looking to trial a new detergent or troubleshoot an application method, you’ll find someone nearby who can help.
Supporting
New Zealand Farmers
Today, Deosan continues to grow, but our focus hasn’t changed. We’re here to back farmers with the right products, practical advice, and local support. From the original TEATX through to our latest detergent and supplement innovations, we remain committed to a single purpose:
Supporting New Zealand Farmers.
