Which? report : Detergents | 01 December 2005
Biological detergents
We tested biological detergents to see how the big brand names compare to supermarket own-brands.
We tested the leading powders and tablets on 15 stains – from fats such as butter, to proteins such as egg yolk, and vegetable stains such as blueberry. And we checked how they affect clothes’ colour and whiteness, too.
We tested biological powder, non-biological powder, biological tablets and colour powder.
Biological powder
The big-name brands’ biggest lead over supermarkets is in biological powders. They knocked spots off the own brands at removing stains. Ariel has the edge over Persil because it gives the fabled ‘whitest whites’.
Biological tablets
Tablets are easy to use, but our tests show that popping a couple in with the wash gives worse results than a biological powder. They’re pretty hopeless at removing fatty stains.
We haven’t named any Best Buys because none of the tablets is that much better than the others.
Non-bio and colour
Non-biological detergents performed well in our tests but the results of the colour detergents were disappointing.
Non-biological powder
Non-bio detergents are best for people who have eczema and dermatitis. They don’t contain enzymes, the part of ordinary detergents that break down food stains. But the Ariel, Persil and Fairy non-bios are still almost as good as the best bio powders.
Colour powder
Colour powders don’t have bleaching agents, which break down the coloured dyes in the fabric. This means they can be poor at tackling vegetable stains, such as tea, wine and tomato ketchup. Our Best Buy is Persil because it’s excellent at coping with protein stains, such as bolognese sauce and baby food.
