Albert Heijn Zwart & Donker liquid detergent

Albert Heijn Zwart & Donker is a specialized liquid laundry detergent specifically formulated for black and dark-colored fabrics. It is a private-label product of the Albert Heijn supermarket chain, the largest grocery retailer in the Netherlands. The product is designed to maintain color intensity and prevent the fading of dark garments over time.

As a store-brand product, it is primarily manufactured within the Netherlands or neighboring European countries to supply the chain's extensive network of stores. The brand has its roots in a small grocery store opened by Albert Heijn in Oostzaan in 1887, which eventually grew into the nationwide powerhouse it is today.

The brand is currently owned by Ahold Delhaize, a major Dutch-Belgian multinational retail and wholesale holding company. Ahold Delhaize was formed through the 2016 merger of the Dutch Ahold and the Belgian Delhaize Group, resulting in one of the world's largest food retail groups with a strong presence in both Europe and the United States.
