Low molecular weight silk fibroin: UnileverRecent Research Landscape

Standard synthetic polymers in hair care cause environmental buildup and inconsistent fiber adhesion. This lever utilizes silk fibroin structural proteins to engineer a biocompatible protective film that enhances tensile strength.

What technical problems is Unilever addressing in Low molecular weight silk fibroin?

Internal hair protein degradation

(6)evidences

Structural weakening and surface porosity of hair fibers lead to breakage and poor texture. Preventing this degradation restores mechanical integrity and aesthetic quality.

Damaged hair fiber structural degradation

(1)evidences

Chemical and environmental stressors compromise the structural integrity of hair keratin. Restoring low molecular weight proteins prevents brittleness and loss of tensile strength.
