EXILVA IMPROVES SPRAYABILITY AND NONDRIPPING EFFECT IN COSMETIC FORMULATIONS
Exilva is a completely natural and infinitely sustainable cellulose-based performance enhancer
that performs as a multifunctional additive in cosmetic systems, as well as increasing your
formulation efficiency, reducing your CO2 footprint and creating exciting opportunities
for innovation.
