Surface-modified aqueous powder dispersions: ShiseidoRecent Research Landscape

Inconsistent particle distribution in high-solids mixtures leads to formulation instability and manufacturing downtime. Precise control of the powder-to-liquid interface ensures batch uniformity and predictable flow characteristics.

What technical problems is Shiseido addressing in Surface-modified aqueous powder dispersions?

Inadequate powder dispersion stability

(12)evidences

Untreated cosmetic powders suffer from agglomeration and uneven distribution in aqueous or oil phases. Resolving these surface inconsistencies ensures uniform application and long-term formulation stability.

Poor powder dispersibility

(3)evidences

Incompatibility between hydrophobic powders and aqueous cosmetic bases leads to sedimentation and poor dispersion stability. Preventing phase separation ensures uniform application and product shelf-life.

Interfacial phase separation instability

(3)evidences

Inconsistent bonding between decorative powders and diverse substrates leads to premature wear and loss of aesthetic integrity. Resolving this ensures long-lasting visual performance and resistance to mechanical abrasion.
