Sodium Propoxyhydroxypropyl Thiosulfate Silica
What is Sodium Propoxyhydroxypropyl Thiosulfate Silica?
Sodium Propoxyhydroxypropyl Thiosulfate Silica is a synthetic derivative of silica, a common mineral compound abundant in the earth's crust. It undergoes chemical modification where propoxyhydroxypropyl thiosulfate groups are linked via sodium, creating fine particles tailored for cosmetics. This ingredient falls into the category of texturizers and fillers, mainly serving as a bulking agent in products like creams, powders, and serums. It functions by expanding the overall mass of the formula, which helps achieve desired consistency, enhances spreadability, and stabilizes emulsions without adding weight or greasiness. The modification improves dispersibility in water- or oil-based systems, contributing to a silky, non-tacky finish. Commonly found in skincare for its inert nature, it supports formulation design by adjusting sensory attributes and economics.
