Available from January 2021, the coating in the new range removes the acrylate plastic applied to the film.

It has therefore joined the British manufacturer's list of products that are officially certified OK Biodegradable Water by TÜV Austria – the highest level of independent certification for fresh water biodegradability in the world.

Ronald Britton commercial director Stephen Cotton said: “This is a significant step for us. Getting our Bioglitter Sparkle product lines certified to this level of biodegradable performance is something we have been striving to achieve for some time now.

“It goes without saying achieving the highest level of independent certification for fresh water biodegradability in the world is extremely difficult, we are so pleased to achieve this.

Bioglitter Sparkle GC is Ronald Britton's brightest range of glitters and the company said it is indistinguishable from the appearance of metallic effect microplastic glitters.

Earlier this year the manufacturer rolled out what it claimed was the world’s first micro-plastic-free iridescent glitter.
