Polycarbodiimide crosslinked polymer dispersions: LorealRecent Research Landscape

Dye washout and fiber damage reduce treatment longevity and consumer satisfaction. These innovations utilize polycarbodiimide-mediated covalent bonding to anchor coloring agents and silicones to the keratin matrix.

What technical problems is Loreal addressing in Polycarbodiimide crosslinked polymer dispersions?

Poor hair color durability

(28)evidences

Insufficient pigment retention and wash-fastness on individual hair fibers. Enhancing color longevity prevents premature fading and maintains aesthetic consistency.

Poor hair color washfastness

(23)evidences

Pigment coatings on keratin fibers suffer from low durability and rapid removal during washing. Improving adhesion and film integrity prevents premature color loss.

Poor color fastness

(19)evidences

Keratin fiber treatments suffer from rapid pigment loss and insufficient adhesion to the hair shaft. Enhancing durability prevents premature fading and maintains aesthetic integrity over time.
