TiO2-embedded mesoporous silica with lower porosity is beneficial to adsorb the pollutants and retard UV filter absorption: A possible application for outdoor skin protection

The purpose of the this investigation was to develop multifunctional TiO2-embedded mesoporous silica incorporating avobenzone to protect against environmental stress through pollutant adsorption and UVA protection in order to explore the effect of the mesoporous porosity on the capability of contaminant capture and the suppression of avobenzone skin penetration. The results showed that the mesoporous formulation with low porosity and a specific surface area showed effective adsorbability and UVA protection, with reduced UVA filter absorption. Hence, it proved the versatility of the developed mesoporous system showcasing its promising potential for outdoor skin protection.
