Alkoxysilane tannic acid keratin crosslinking: HenkelRecent Research Landscape

Standard keratin dyes wash out easily and damage hair fibers through harsh oxidation. This lever utilizes organosilane polymerization to anchor pigments within the keratin matrix for permanent color without structural degradation.

What technical problems is Henkel addressing in Alkoxysilane tannic acid keratin crosslinking?

Poor hair color washfastness

(16)evidences

Keratin fibers suffer from rapid pigment loss and color leaching during repeated washing cycles. Enhancing pigment retention through chemical anchoring prevents premature fading and maintains aesthetic longevity.

Keratin dye washfastness degradation

(13)evidences

Pigments and dyes applied to keratin fibers suffer from rapid leaching and poor wash fastness. Improving retention ensures long-lasting aesthetic performance and reduces the frequency of chemical re-treatment.

Poor dye wash fastness

(6)evidences

Keratin fibers suffer from rapid pigment loss and color fading during routine washing. Improving pigment retention ensures long-lasting aesthetic results and reduces the frequency of chemical re-treatment.

Keratin treatment reagent instability

(2)evidences

Chemical and environmental stressors cause permanent damage to the hair shaft integrity. Preventing this breakdown maintains fiber strength and surface smoothness.
