Which Is Better, Foam Soap or Liquid Soap?

Sep. 01, 2020

Because solid soap is not easy to dry and preserve and is easy to contaminate, solid soap is rarely used to wash hands in medical institutions. Due to the convenience of storage and use, more and more liquid soaps and foam soaps enter medical institutions or homes. So, which one is better, liquid soap or foam soap?

Liquid soap is actually a liquefied "soap". Like soap, liquid soap is mainly composed of sodium fatty acid and is essentially saponified from animal or vegetable oils.

A recent study stated that foam soap may not be as effective as liquid soap in removing bacteria, and the use of foam soap may cause infection, so it is recommended to use liquid soap when choosing soap.

Liquid Soap

According to the study, after washing hands with foam soap, the number of bacterial colonies on each hand dropped from 3.6 to 2.6, and the number of bacterial colonies with liquid soap dropped from 3.8 to 1.2. The difference was statistically significant. Because foam soap comes out directly in the form of soap bubbles, and liquid soap produces soap bubbles during rubbing and pressing once at the same time, foam soap contains less soap than liquid soap. Liquid soap has the advantages of good solubility, strong detergency, easy to rinse, easy to quantitative control, and less irritation to the skin.

Researchers have found that foam soap may give people a false sense of security and cause the spread of bacteria. However, due to the small number of experimental samples and the lack of rigorous methods, more experiments are needed to verify this conclusion.

"Illness comes from the mouth" is the truth that we have been told since we were young. In many cases, the disease is caused by unclean hands. Washing hands with running water and soap have become the simplest and most effective way for us to prevent diseases. A dazzling array of handwashing products, how do we choose, perhaps you have already drawn a conclusion from this research.
