Answer:
- The discovery of the French Nicolas Leblanc and Michel Chevreul on how to make soaps.
- The end of the luxury products tax on soap.
Explanation:
In 1800 the soap became a popular product widely used in practically all purposes. In addition to the concepts of hygiene and cleanliness having increased at that time, the discovery of the French Nicholas Leblanc and Michael Chevreul about the manufacture of soap, allowed this product to be seen in the markets in a more recurrent way. This is because the soap was laboriously manufactured, with difficult ingredients, however these two Frenchmen managed to develop an alternative manufacture that was fast and effective, allowing the soap to be made available to everyone.
In addition, it was during this period that the soap stopped being taxed as a luxury item, which left it with affordable prices for all families.

This was done because the Salem authorities wanted to show that no one was free from the supremacy and control that they had in the city, showing that any citizen was passive to face the terrible yoke established by them.
