The chemistry of soap manufacturing stayed essentially the same until 1916, when the first synthetic detergent was developed in Germany in response to a World War I-related shortage of fats for making soap.
While working for Proctor & Gamble, Dennis W. Weatherby invented a detergent that could be used with other products containing bleach, had a yellow color, a lemon scent and also did not stain dishes or the dishwasher.
In 1987, Weatherby received the first patent for automatic dishwashing detergent. The product was labeled as Cascade and became a household brand quickly.
