Procter & Gamble (P&G)

P&G practically invented modern detergent with Tide in 1946. In North America, they dominate the laundry aisle with heavyweight Tide and its mid-tier counterpart Gain.
In the UK, they market Ariel, Bold, Daz, and Fairy Non Bio.
P&G doesn’t routinely sell detergent in Australia or New Zealand, although Ariel and Tide are increasingly available as detergent pods.
