A stability study has been conducted by adding 0.3% Glydant Plus® Liquid in a broad variety of personal care products, and by checking viscosity, pH, color and homogeneity of the end products after one month at room temperature and 50°C. Glydant Plus® Liquid proved to be compatible with all of the tested products. No major change was observed for either criteria.
Water-white to light yellow color of Glydant Plus® Liquid is stable when stored at 23°C.
Glydant Plus® Liquid homogeneous phase is stable when stored at 23°C. After storage of three months at 40°C, one month at 50°C and three months exposure to sunlight, Glydant Plus® Liquid maintains its homogeneity.
