Best Answer

DAWN was introduced as a new dishwashing liquid by the Procter & Gamble Co. in 1973. It was better for grease removal because it contained more detergent than other brands. In 1974, James A. Hellyer, a 31- year old chemical engineer and two co-workers discovered how to significantly improve the "grease handling" ability of DAWN. This invention received strong patent protection under U. S. Patent No 4,133,779, allowing DAWN to be unmatched for decades in satisfying the "grease handling" needs of consumers for washing dishes. Over the years, a wide range of other remarkable uses have been found for DAWN.
