HELSINKI – Scientists in Finland have developed a new, natural wax coating which they say makes an affordable water-resistant and breathable coating for garments without the use of harmful chemicals.

It comes amidst growing concern over the use of potentially harmful fluorine-based chemicals in waterproof clothing and increasing demand for more sustainable alternatives.

Researchers at Aalto University in Helsinki used carnauba wax to develop an ecological and water-repellent finish for wood-based and other cellulose fibres, which they say also retains the breathability and natural feel of the textile.
