Polycarbodiimide non-carboxylic anionic network: LorealRecent Research Landscape

Inconsistent pigment retention and fiber damage occur when hair dyes fail to bond permanently to keratin. These innovations utilize polycarbodiimide chemistry to crosslink anionic thickeners and hydroxyl-functional compounds into a durable protective matrix.

What technical problems is Loreal addressing in Polycarbodiimide non-carboxylic anionic network?

Inconsistent hair color results

(28)evidences

Inadequate pigment retention and washfastness on hair fibers. Improving color longevity ensures consistent aesthetic results and reduces the frequency of chemical re-treatment.

Poor colorant wash fastness

(19)evidences

Keratin fiber treatments often suffer from rapid fading and insufficient wash fastness. Improving the structural integrity of the coloring layer prevents premature pigment loss.

Poor hair color washfastness

(13)evidences

Keratin fiber treatments suffer from rapid pigment loss and low durability against washing. Improving adhesion and structural integrity prevents premature fading and mechanical degradation.
