SYNTHALEN W600 is an anionic acrylic copolymer supplied as a low viscosity o/w emulsion. Its water dispersions, when neutralized, are characterized by medium viscosity, high yield value and clarity in a large range of pH and show typical pseudoplastic behaviour. In water the polymer starts to swell at pH 6. In the presence of other components such as surfactants, the viscosity builds up at lower pH. Fig.3 shows the viscosity and yield value behaviour vs. pH of a composition containing 10% of Sodium Laureth Sulfate and 2% of Cocoamidopropyl Betaine thickened with 6% of SYNTHALEN W600. ts immediate dispersion, clarity and good compatibility with surfactants make SYNTHALEN W600 the ideal polymer for the formulation of surfactant systems, especially when high suspending ability is required. Many types of insoluble ingredients are easily suspended and stabilized including: • Beads and capsules • Polyethylene • Walnut shell • Luffa • Pumice • Pearlizing and opacifying agents • Pigments • Zinc pyrithione SYNTHALEN W600 also aids in the stabilization of insoluble silicones and other insoluble liquids, such as oils, vitamins, fragrances, in surfactant systems. For example, milky and creamy shower gels, characterized by a high degree of whiteness and good emolliency, can be prepared using this polymer together with a variety of oils (dimethicone, cyclomethicone, avocado oil, macadamia oil, sunflower oil, vitamin E, etc.). Therefore it is suitable for formulating clear fluid gels as well as for stabilizing oil-in-water emulsions. Thanks to its resistance to alkali, SYNTHALEN W600 can be used in hair styling products and in any formulation where a high pH is required. Normal percentage of use is between 1 and 10 % depending on type of formulation and final desired viscosity. Synthalen W600 is a product of 3V Sigma
