Bio-D is a British brand of environmentally friendly cleaning products. The products are not eco-certified, but consist primarily of plant-based cleaning substances. They contain no petrochemicals, phosphates, preservatives, petroleum-based substances, optical brighteners, halogens, or genetically modified organisms. Bio-D product packaging is partially made of recycled materials (paper and plastic). They include large bottles of several liters and paper bags to avoid having to buy large quantities of small packages. Bio-D products include laundry detergent, cleaning and dishwashing detergent, and biodegradable trash bags.
