Today in Europe there are only a few brands that have compact powders: Persil megaperls by Henkel, Ariel compact by P&G and supermarket own brands by Dalli Werke, Thurn and McBride/Chemolux (Formil, Tandil, Bravil, Ja, Denkmit etc.). They are sold in virtually 2-3 countries. All of them have great bleaching system, but are granulated with zeolites so they contain huge amounts of them. For whites they are OK, but for colous - not al all. In fact I wouldn't use powder with such high zeolite content all the time even for whites. Yes, the bleaching system is fantastic, but zeilites are insoluble plus they increase the friction between the fabrics which leads to rapid wear. That's why compact powders usually contain very active cellulase enzyme - to cover the negative effects from the zeolites. The manufacturers must reformulate soon.
Maybe you've noticed that most of the powders shank. For example Dixan's dose was 80 g/135 ml and now it's 65 g/115 ml (in Bulgaria Persil's dose was 100 g/142 ml, now it's 70 g/108 ml), Skip's was 80 g/135 ml, now 70 g/110 ml. This is not true compacting, because they don't change the bulk density, just reduce the dose by removing part of the heavy inactive ingredients.
