Soaps: What are the Differences?

Is there really a difference between dishwasher detergent, laundry detergent, dish soap, hand soap and shampoos? Actually, yes! There are some major differences between these soaps, which means they are NOT interchangeable.

Most soaps have the same, or a very similar, acting ingredient called sodium lauryl sulfate.  This ingredient is the primary cleaning agent that works to get rid of oils and dirt. This does most of the heavy work. The other ingredients do other things, though most are needed. For example, Cocamide DEA makes soap foam, but doesn’t actually help clean (NPR). So if the core of all soaps are the same, they should be interchangeable, right? Actually not.

The difference between all soaps is the environment in which they are meant to be used. Things like temperature and products being cleaned are major factors in the development of soaps. These factors can determine the pH and amount of bleach put into each type of soap. Dishwasher detergents have high pH levels and lots of bleach to clean via brute force. Laundry detergents use small amounts of bleach to help clean without damaging the clothes. Hand soaps and shampoos have no bleach and have almost neutral pH levels so they won’t damage your skin or hair (University of Wisconsin – Madison).

Knowing the differences won’t only save your appliances and skin, but it can help you decide what soaps to use when. Here are some easy do’s and don’ts for soap uses.

  1. Once when I was a teenager I was on a 50 mile wilderness backpacking trip, and wanted to wash at least one of my shirts before re-entering civilization, because all my shirts smelled REALLY BAD by the end of my trip. But of course no one brings laundry detergent on a wilderness backpacking trip. I tried scrubbing the shirt with dish soap, then hanging it on a rope in a fast-running stream all night long. Guess what? The next morning the shirt still smelled really bad. You really do need the right kind of soap for the right job.

  2. I used dish soap instead of dishwasher detergent in the dishwasher once; it resulted in a big foamy mess all over the kitchen floor 🙂
