ULTRATHIX P-100 polymer thickener is a multi-functional rheology modifier. This thickener allows formulators to create quick-break textures due to its shear-thinning rheology and refreshing sensory perception. In skin care formulas, this thickener offers emulsion stabilization, reduces tack, and improves aethetics of hydroalcoholic sprays, and enhances skin feel properites. The unique ability of this thickener to supend pigments, especially titanium dioxide, makes it ideal to use in foundations, mascaras and other color and sunscreen applications to enhance stability and esthtetics.
