Soap and the effect it has on the Surface Tension of Water

Watch how the surface tension of water completely changes when soap is introduced.

This video was made to assist in explaining our blog post on how our organic soap bars lather without SLS.

In the video, one can notice how the water droplets that are placed on waxed paper bead up into tiny dome-like balls due to surface tension.

Then see what happens to the surface tension of the water when soap is introduced. Soap is a natural surfactant, which is short for "surface active agent." Surfactants reduce the surface tension of water.

Water will normally hold to itself because each water molecule is surrounded by and attracted to other water molecules. The property of surface tension causes water to bead-up on surfaces, like my wax paper. For the water to spread and wet a surface (like your skin) – you need surfactants.
