Citrefine International Limited is a British company founded over 25 years ago. Committed to producing a naturally sourced active substance that is effective and safe for both consumers and the planet, Citrefine has been at the forefront of developments in this market for many years.
More than a quarter of a century ago a tropical disease specialist in the British Navy, Dr Paul Clarke, travelled to south-east Asia and saw first-hand the devastation caused by mosquito-borne diseases. On this same trip he learned about an age-old use of Eucalyptus citriodora oil as an insect repellent and wondered if this locally sourced remedy, involving a simple conversion of the essential oil, could be brought to the aid of other regions.
Working with his friend and business partner, Ian Hughes-Guy, the pair undertook a series of foundational tests to determine if the belief behind the oil’s repellency could withstand the rigour of scientific testing. The results were remarkable – matching those of the strongest synthetic alternatives. They called their product Citriodiol®, which recognised the citrus smell of the lemon eucalyptus oil and the high p-menthane-3,8-diol content resulting from its conversion.
