Shampoos
Today's hair care products increasingly require raw materials that are safe and effective while addressing multiple needs. Cellulose polymers are used in shampoos both as a thickener and lather enhancer.
Minimize Surfactant usage/maximize mildness
Small concentrations of Joinway cellulose can replace greater amounts of salt and surfactant while maintaining desired product viscosity - minimizing surfactant amounts of salt and surfactant while maintaining desired product viscosity. The savings in surfactant may offset the cost of the Joinway.
Effect of interfacial gelation on shampoo lather
In most solutions as temperature rises, bulk viscosity drops and the thin liquid between bubbles promotes drainage. Interfacial gelation slows this process . Bulk viscosity still drops as the solution is heated, but at the same time, an interfacial gel forms between and around bubbles. Thickening and reinforcement of bubble walls counteracts the effect of lower viscosity. Liquid can't drain as quickly, and bubbles remain intact longer, stabilizing the foam.
Enhance lather characteristics
Through a unique property-interfacial gelation-Joinway products are polymeric thickeners that actually contribute to increased foam stability at shampooing temperatures. Interfacial gelation is the formation of polymer networks at air/water interfaces when a dilute solution of Joinway is heated. In a shampoo, an interfacial gel of concentrated polymer forms between and around bubbles. This gel structure thickens and reinforces bubble walls and slows the rate at which water can drain away. Bubble walls do not thin out and disintegrate as rapidly.
