Sodium Tripolyphosphate (STPP) Life Science

STPP’s sequestering and chelating properties make it a highly effective water softener for cleaning and detergency applications.

Overview

STPP acts as a builder in cleaning product formulations by sequestering calcium and magnesium ions, preventing interference with surfactant performance.

This improves cleaning efficiency by enhancing soil removal, dispersing dirt and preventing soils from reattaching to cleaned surfaces.
