Color-treatment processes, such as oxidative dyeing tend to remove the hydrophobic layer from the hair surface. Without a hydrophobic surface, dye molecules may leach out faster from hair fibers during typical washing and conditioning practices with surfactant-containing products. ChromoHance™ 113 polymer restores a hydrophobic shield, aiding in the preservation of color vibrancy and significantly reducing leakage of color molecules.
Consumer-perceivable hair color maintenance
In panel studies, consumers perceive color maintenance, conditioning and shine across a range of color shades when following a shampoo and conditioning regimen with formulations containing ChromoHance™ 113 polymer. When compared with control formulations containing no polymer, consumers observe a very significant improvement in maintenance of color vibrancy.
Color conservation of red hair
Red hair dye is by far the most difficult color to guard against wash-out and color-fade. Using a commercial permanent red hair color as a test case, the anti-fade performance of this oxidative dye is tested during a shampoo and conditioner regimen containing 1% active level ChromoHance™ 113 polymer.
Proven in rinse-out and leave-in systems
An easy-to-use clear aqueous solution, the polymer is proven useful in both rinse-out and leave-in systems at low-use levels. ChromoHance™ 113 polymer is compatible with most hair care formulations and ingredients at levels that range from 1 to 5% (as sold).
