Which are the Ariel Tabs?
We've had a few formats here:
P&G Ariel and Daz : Tablets (compressed powder in foil wraps that dissolves in the drawer)
P&G Ariel and Daz Liquitabs (highly concentrated liquid in a dissolvable pouch)
P&G Ariel Pods (3 compartment pod, same as Tide)
Unilever Persil and Surf Capsules (liquid in a dissolvable pouch)
Unilever Persil Gel Tablets which were compressed powder with a hardened gel. These were put in a net bag directly into the drum.
Unilever Persil and Surf Tablets : for use with a net in the drum without the gel section.
Unilever Persil and Surf tablet that dispense in the drawer (compressed powder)
Own brand products (mostly McBride) also produce dissolvable liquid capsules for all the major supermarkets.
Solid powder tablets that dissolve in the drawer are also produced for all the supermarkets by McBride and a few others.
McBride (on its website) claims to be the first to produce liquid capsules back in 2001.
