![]() A strong gel character gives the impression of a high-quality product to a majority of customers. Gels with a high yield point or a strong gel character are perceived by the customer as having "more volume". The yield point corresponds directly with the elastic properties of the sample at rest. Whereas the viscosity of a hair gel is a particularly important parameter during production and for product evaluation during the development, the yield point is particularly important for the customer's evaluation of the end product. Its consistence is viscoelastic and can be tested with a rheometer.Ĭonstantly checking a product’s viscosity and yield point guarantees a consistently high quality. It is frequently a finely dispersed system consisting of at least a solid and a liquid phase, forming a three-dimensional network. Gel is an abbreviation of “gelatin“ and has the same Latin root as “jelly“ (thickened fruit or meat juice).
