Polycarbodiimide silicone acrylic crosslinking: LorealRecent Research Landscape

Pigment washout and mechanical degradation reduce the longevity of hair color treatments, which is mitigated by engineering a durable polymer matrix using carbodiimide-carboxylic acid reactive chemistry. This covalent anchoring of silicone copolymers ensures color retention and structural integrity against repeated washing.

What technical problems is Loreal addressing in Polycarbodiimide silicone acrylic crosslinking?

Poor hair color washfastness

(33)evidences

Chemical treatments and pigments fail to remain fixed to the hair fiber after washing or styling. Improving adhesion and resistance to environmental degradation ensures long-lasting aesthetic results.

Poor color fastness

(18)evidences

Insufficient pigment retention on keratin fibers during repeated washing. Enhancing durability prevents premature fading and maintains aesthetic consistency.
