Difference Between Soap & Synthetic Detergent

by Owen Rogers ; Updated September 28, 2017

Soap and synthetic detergents are generally thought of in the same light. They are both used for cleaning, but are produced in different ways and have different advantages and disadvantages.

Ingredients

The most basic difference between soap and detergents is the ingredients. Soap is made primarily from some type of natural fat and lye. Detergents, on the other hand, are made from petroleum products and generally contain preservatives and antibacterial agents.

Hard Water

Soap and detergents react differently to hard water, which is water that has high concentrations of minerals. Soap reacts with these minerals by forming a residue that may remain on fabrics, dishes or whatever is being cleaned. Detergents do not have this undesirable reaction.

Considerations

Detergents for dishwashers and laundry often have chemically induced, high pH values. These detergents would irritate skin. Synthetic detergents can also cause allergic reactions in some people. However these detergents have greater cleaning power than soap.

Byproducts

According to Clearwater Soap Works, soap can be produced without any industrial byproducts. Natural soap is also completely biodegradable. The same cannot be said of synthetic detergents.
