These surfactants can lower the surface tension of water, reducing the amount of work needed to create the foam and increasing the stability of the bubbles that are within it. Whatever your choice we can guide and assist you with the supply of speciality soap bases. That means it is also a chemical substance that reduces the surface tension in water. Though a preservative is always a good idea with skincare products that contain water, this liquid soap is fine to use without one, permitting that it's used within a month.

This is especially true when it comes to cleansers. There are two main types of blowing agents: gases at the temperature that the foam is formed, and gases generated by chemical reaction.
