IKEA has banned the use of chlorine bleaching agents in the production of textiles and paper products due to the negative impact on the environment. Renewable material (cotton). All the cotton in our products comes from more sustainable sources. This means that the cotton is either recycled, or grown with less water, less fertilizers and less pesticides, while increasing profit margins for the farmers. IKEA has strict requirements for the use of phthalates in all our products, and we have totally banned them in children’s and food-contact products. Since 1996 IKEA has banned harmful dyes, e.g. azo dyes, in textile and leather production. No optical brightener has been used.
