After more than a quarter of a century, Citrefine International are proudly remaining true to the vision of it’s founders, serving the repellent market by providing a highly effective product combining nature’s wisdom with robust scientific testing for the benefit of our communities and the planet.

Citrefine International Limited is a family-run British company founded in Leeds, England over 25 years ago. One of Citrefine’s founders, a specialist in tropical medicine, recognised the need for an effective and naturally sourced option to protect against the increasing threat of vector borne disease. His primary concern was finding a low-toxicity alternative to DEET, with efficacy rigorous enough to protect against Malaria and other diseases. Through a multitude of clinical laboratory tests and field trials, it was proven that Citriodiol® readily met this need, and it is now used in well-known insect repellents the world over. Leading authorities worldwide now recognise Citriodiol’s® first-rate efficacy making it the only plant-based repellent with this level of accreditation.

Alongside our UK headquarters, Citrefine established an office in the USA to support our expanding customer base, and now export products globally. We offer a tailored approach to our customers encompassing regulatory, technical, commercial and operational expertise. Our in-house regulatory team and scientific laboratory can offer help and support throughout the process of bringing an insect repellent to market.

“Unlike many of our competitors, our sole focus is the naturally sourced insect repellent market.  We are experts at the forefront of development in this field”
