Pumice powder is quite a versatile substance and has many uses in both consumer and industrial applications.
Scrubs & Cosmetics
Fine grain pumice powder has been added to cosmetics, soaps, and scrubs for many years. A very popular recipe is known as mechanic’s soap, and was used by mechanics and engineers to scrub away the oil and grease from a day’s work.
Nowadays it is quite common in shower gels, cleansers, facial scrubs, and foot scrubs. Pumice is growing in popularity due to being a common replacement to plastic micro-beads, which are known to harm our environment and drinking water.

Abrasive & Polishing Applications

In addition, because pumice powder has a neutral pH and is generally inert, it is often suitable in cases where other materials may not be used due to acidity, rust, or other issues.
