Hydration innovation: Scientists unveil groundbreaking dry mouth remedy
Source: scitechdaily.com Author: University of Leeds Proof of concept of new material for long-lasting relief from dry mouth conditions. A novel aqueous lubricant technology designed to help people who suffer from a dry mouth is between four and five times more effective than existing commercially available products, according to laboratory tests. Developed by scientists at the University of Leeds, the saliva substitute is described as comparable to natural saliva in the way it hydrates the mouth and acts as a lubricant when food is chewed. Microgel Technology Explained Under a powerful microscope, the molecules in the substance — known as a microgel — appear as a lattice-like network or sponge which bind onto the surface of the mouth. Surrounding the microgel is a polysaccharide-based hydrogel that traps water. This dual function will keep the mouth feeling hydrated for longer. Professor Anwesha Sarkar, who has led the development of the saliva substitute, said: “Our laboratory benchmarking reveals that this substance will have a longer-lasting effect. “The problem with many of the existing commercial products is they are only effective for short periods because they do not bind to the surface of the mouth, with people having to frequently reapply the substance, sometimes while they are talking or as they eat. “That affects people’s quality of life.” Study Findings and Benchmark Results Results from the laboratory evaluation, “Benchmarking of a microgel-reinforced hydrogel-based aqueous lubricant against commercial saliva substitutes,” are reported today (November 20) in the journal Scientific Reports. The performance of the [...]
