Which Fortune 500 company introduced Tide laundry detergent in 1946?

Procter & Gamble introduced Tide laundry detergent in 1946.

Tide was developed as a heavy-duty synthetic laundry detergent for washing machines. Its launch followed earlier advances in synthetic detergents, which could clean effectively in hard water and did not form soap scum as traditional soaps did.

The brand became one of Procter & Gamble’s best-known consumer products and helped establish the company as a major household-goods manufacturer. Tide’s orange-and-yellow packaging became particularly recognizable in the United States.

Tide is sometimes confused with Cheer or Gain, other laundry brands associated with Procter & Gamble. Tide’s original significance was its positioning as a powerful machine-washing detergent, not simply a scented soap. The product has since expanded into liquid detergents, pods, stain removers, and other laundry-care products.
