Toxicological Safety, Antimicrobial Efficacy, and Sensory Evaluation of River Sand-Derived Mica From Bangladesh: A Comprehensive Assessment for Cosmetic Applications.

ABSTRACT:

Background

Mica is widely applied in cosmetics, construction, automotive, electronics, defense, and medical industries, particularly important in cosmetics as an ingredient in foundations, eyeshadows, lipsticks, and nail polishes for its pearlescent and shimmering effects.

Aims

To evaluate the suitability of mica minerals from Bangladeshi river sands for cosmetic applications by investigating their chemical composition, heavy metal content, potential for skin irritation, and antimicrobial activity.

Methods

The chemical composition, crystallographic structure, and heavy metal content of mica samples were analyzed using X-ray fluorescence, X-ray diffraction, and Atomic Absorption Spectroscopy. Non-carcinogenic and carcinogenic risks were evaluated using USEPA models (AD
