From Pathfinder Wiki
The chemistry of soap manufacturing stayed essentially the same until 1916. During World War I and again in World War II, there was a shortage of animal and vegetable fats and oils that were used in making soap. Chemists had to use other raw materials instead, which were “synthesized” into chemicals with similar properties. These are what are known today as “detergents.” [1]
