Foaming Soap vs Regular Hand Soap
Regular hand soap is usually a gel-type substance that is either clear or creamy. This is used with a gel soap pump top that allows the liquid to easily flow up the tube and into your hand. Regular hand soap is not meant to be diluted with water. Foaming hand soap is made from a concentrate such as pure castile soap that is meant to be diluted with water. You use a foaming pump top to use this soap which adds air to the mixture when pumping into your hand. They both work equally well if used correctly!
