Organic and inorganic UV filters often suffer from rapid degradation or insufficient coverage across the full UV spectrum. Enhancing stability and breadth of protection prevents formulation breakdown and skin damage.

Inconsistent dispersion and large particle size reduce formulation stability and optical transparency. Achieving uniform sub-micron distribution prevents sedimentation and enhances photoprotective efficacy.

Current methods fail to precisely quantify UV protection levels during formulation and manufacturing. Reliable performance forecasting reduces the risk of sub-standard product safety and regulatory non-compliance.
