Product Description

Green Stone Swiss supplies high-purity Caffeine manufactured under strict GMP-aligned quality systems, ensuring consistent batch-to-batch performance for professional cosmetic and personal care brands worldwide. Our direct factory supply model delivers reliable bulk quantities with full technical documentation and free sample support.

Caffeine is the xanthine alkaloid used in leave-on eye and body formulas aimed at a puffy look. It is not a stimulant drug in this use and not a fragrance. This grade is a white crystalline powder that dissolves in warm water.

Eye gels and contour serums continue to specify this INCI because the assay and a clear use range are easy to control. Cosmetic-grade Caffeine remains a high-volume bulk active for eye-area systems.
