It will produce crystal clear gel products and thicken the aqueous phase of cosmetic emulsions. It can be also be used to efficiently thicken shampoos, body washes and shower gels.\u003c\/p\u003e\n\u003cp\u003eOne of the problems normally associated with this and other water-soluble thickeners is the tendency of the particles to agglomerate or lump when first wetted with water. The high-purity cosmetic grade of \u003cstrong\u003eHydroxyethylcellulose\u003c\/strong\u003e we offer is an R-grade, designed to be added to water without lumping, and thus greatly facilitating solution preparation. It is also the most efficient grade of non-ionic thickener available from the manufacturer.\u003c\/p\u003e\n\u003cp\u003eHydration of the R-grade particles has been inhibited. When the particles are added to water, they disperse without lumping, and following a predetermined delay, begin to dissolve. This process permits the preparation of clear, smooth, viscous solutions in a short period of time by simply adding the R-grade to water and stirring until the polymer is completely dissolved to prevent settling of the particles.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eINCI:\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eHydroxyethylcellulose\u003c\/p\u003e\n\u003cp\u003e** 50 lb bag is boxed and shipped separately from the balance of an order.

Hydration time is markedly affected by two factors: pH and temperature of the water. A higher temperature and a higher pH decrease the hydration time, but a too high temperature or pH can result in lumping. So, it is recommended that it be added to room temperature water with a neutral pH. Once hydrated, it can be heated and the pH can be adjusted as may be needed.\u003c\/p\u003e\n\u003cp\u003eThe technical data provided by the manufacturer advises HEC will quickly hydrate and form a clear gel even in cold water; however, this has not been our experience with the material. Even at cooler ambient temperature the polymer may require stirring for hours to completely hydrate and swell.
