Pumice Propanediol ●
TL;DR. This ingredient is used mainly as a physical exfoliant and texture additive, with a humectant-solvent component that helps disperse the particles in rinse-off or scrub formulas.
What does Pumice Propanediol do in a cosmetic formula?
This ingredient is used mainly as a physical exfoliant and texture additive, with a humectant-solvent component that helps disperse the particles in rinse-off or scrub formulas.
Is Pumice Propanediol clean?
From a clean-beauty perspective, it is generally straightforward and not a common restricted-list concern. Tolerance depends mostly on particle size, shape, and use pattern, since aggressive mechanical exfoliation can be too much for sensitive or compromised skin.
Is Pumice Propanediol sustainable?
This material combines a naturally occurring mineral component with a solvent-humectant that is often made by fermentation of plant-derived sugars. The mineral portion is inert rather than biodegradable, while the solvent portion is readily biodegradable and typically has a favorable environmental profile when bio-based.
Is Pumice Propanediol COSMOS-approved?
It is generally compatible with COSMOS-natural style formulas when the mineral source and the solvent production route meet the standard’s requirements. It fits Green Chemistry best when the solvent fraction is bio-based, readily biodegradable, and made through lower-impact fermentation processing.
How does Pumice Propanediol work chemically?
This is a particulate exfoliating material paired with a small, water-miscible diol that can also support hydration and dispersion in aqueous systems. Performance is driven by particle size distribution, particle morphology, and formula viscosity, and it is typically most appropriate in rinse-off products where contact time and mechanical pressure are controlled.
