Insoluble screening agents and particulate filters frequently undergo phase separation or precipitation in complex formulations. Stabilizing these components prevents formulation collapse and ensures uniform photoprotection.

Poor distribution of particulate filters leads to uneven skin coverage and reduced photoprotection. Achieving a stable, non-agglomerated suspension ensures consistent SPF performance and improved sensory properties.

Skin cell degradation and premature aging caused by solar radiation exposure. Preventing this biological damage is the primary driver for developing stable topical barriers.

Mineral UV filters tend to cluster, reducing surface area and creating uneven coverage on keratin surfaces. Preventing this ensures uniform photoprotection and eliminates white casting.
