Block copolymer inorganic particle dispersion: ShiseidoRecent Research Landscape

Surface accumulation of airborne pollutants degrades skin health and aesthetic finish, which is mitigated through steric stabilization of inorganic particles using block copolymers. This engineering approach ensures a uniform protective barrier that prevents particulate adhesion.

What technical problems is Shiseido addressing in Block copolymer inorganic particle dispersion?

Unstable pigment particle suspension

(2)evidences

Inorganic particles in liquid cosmetic formulations tend to clump or settle over time. Preventing this degradation ensures consistent product efficacy and shelf-life.

Harmful particle skin contact

(1)evidences

Uncontrolled accumulation of fine particulate matter on surfaces leads to contamination and degradation. Preventing this interaction maintains surface integrity and functional cleanliness.
