If you belong in the latter category, this guide can help you understand how bar soaps and body washes score on different fronts. Once you’re aware of this, you may find it easier to choose. So, read on to find out all about what bar soaps and body washes are, and how they compare.

In the bar soap vs body wash contest, the former is the one that a vast majority of the people are more familiar with. Still, let us try to define this product we know so well and love so much. Soaps have been around for ages. In fact, the bar soap is so ancient that nobody really knows its exact origins.

The earliest available records indicating the existence and the use of soap date back to 2800 BC, in ancient Babylon. A formula for soap used by the people of Babylon has even been found on a clay Babylonian tablet dated 2200 BC. The formula consisted of water, alkali, and cassia oil, which is similar to soap as we know it today. Other records of the use of soap in ancient civilizations suggest that the ancient Egyptians, the Romans, and the people of ancient China and medieval Europe all used variations of this formula as cleansing solutions.

Essentially, soap is a long chain salt of a fatty acid and an alkali, with a pH that is usually between 9 and 10. The word "soap" is also used to describe a variety of products that used for cleansing and lubricating purposes. A bar soap can also be used around the house for performing regular chores like bathing, washing clothes, dishwashing, and other routine kinds of cleaning. Soaps in their chemical form are used in industries as thickeners, as components of lubricants, and as precursors to catalysts.

Today, bar soaps come in many forms, including the following:

  • Personal soaps—These soaps are made specifically to meet the needs of personal hygiene and are also called bath soaps.
  • Antibacterial soaps—These bars have specific formulations that help prevent viruses and bacteria from spreading.
  • Body and hair soaps—They are ideal for washing the grime off both body and hair, eliminating the need to shampoos.
  • Novelty soaps—They’re soaps that come in various shapes like ducks, lions, elephants, or other animals and things made to amuse children and encourage them to bathe.
  • Perfume soaps—These are soaps that contain additional ingredients that give them distinct fragrances like roses, lavender, or citrus.
  • Guest soaps—They’re tinier versions of bath soaps, and they often come in attractive shapes like flowers or seashells. They’re typically used in the guest bathrooms.
  • Glycerin soaps—As the name suggests, these soaps contain glycerin, which makes them translucent and infuses a moisturizing property in them.
  • Medicated soaps—This variety includes ingredients like antiseptics and disinfectants that give it a medical edge.
  • Kitchen soaps—These soaps can either have mild abrasives or tougher dish detergents for deep cleaning.

And then, aside from these kinds of soaps, there’s also another variety–liquid soap. This brings us to the next contender in the bar soap vs body wash dispute.

What Is Body Wash?

Body wash may be new to the scene compared to soap, but body wash has its own edge in the whole bar soap vs body wash debate. But first, it's important to understand exactly what a body wash is. Body wash is a liquid cleanser that use mild surfactants to cleanse the skin and wash off the dust of everyday life from the pores.

A related product in this conversation is shower gel as it can be easily confused with body wash. Shower gels and body washed use similar chemical formulations, but the difference between them lies in their consistency. Shower gels are thinner, making them better suited for warmer climates, which body wash is generally thicker and more moisturizing, making them better for cool climates.

Another subcategory in the body wash family is the body scrub. These products are body washes that come with tiny granules in their mix, making them slightly coarse to touch. They are typically thicker than body washes, and they work better at scrubbing away dead skin cells on the body, thus allowing moisture to settle in and replenish your skin’s vitality.
