Precipitated silica’s high oil absorption, mattifying effect, and rheological control make it a key ingredient in cosmetics. As a thickener, it stabilizes emulsions in sunscreens and lotions, while its porous structure enables controlled release of active ingredients. In powder formulations, it prevents caking and improves skin feel. Fumed silica, with its smaller particle size, is used in antiperspirants for its flow-aiding properties. Regulatory approvals (e.g., FDA GRAS status) and nanoscale safety assessments ensure its continued use in sensitive applications. The rise of mineral-based cosmetics further boosts demand for high-purity silica.
