It can be difficult for customers to make completely informed choices.
According to
Edward Bulmer
, an interior designer and the founder of his own brand focusing on plant-based products,
eco paint
A brand ensures transparency by comprehensively detailing each individual ingredient utilized.
Paint manufacturers aren’t required to disclose their formulations, so typically we only learn about the water content or some trendy eco-friendly component such as crushed olive pits,” he says. “A straightforward listing of all components would benefit consumers, although this may not seem as attractive. For example, why reveal the inclusion of plastics— which eventually degrade into microplastics —when one can simply claim ‘no intentional addition of microplastics’?
Legislation and transparency will be crucial elements in shaping the future of eco-friendly paints for interior designers.
