Pumice

Pumice (CAS 1332-09-8), also known as pumicite in its fine powdered form, is a naturally occurring volcanic mineral processed for abrasive, filtration, and surface treatment applications.

Where is Pumice used?

• Personal care and cleaning: mechanical exfoliation in hand soaps, foot scrubs, and scouring pastes
• Textile and denim: pumice stones for stonewashed effects and surface distressing on fabric
• Construction: lightweight aggregate in concrete, plaster, and insulating blocks where reduced density is a target
• Leather processing: buffing and surface preparation to achieve consistent texture before finishing
• It also serves as a functional filler and abrasive agent in industrial and consumer product manufacturing.

Good to know: Cosmetic grades are subject to tighter particle size and purity controls than technical grades.

Commercial specifications

• Particle size is the primary specification variable across grades
• Bulk supply is common for industrial buyers, with finer mesh grades available for personal care and cleaning product formulators
