Nanostructured Surface Treatment Enables the Combination of Nano-particulate ZnO and TiO2 with Acrylate-based Polymers in Cosmetic Formulations

Andre V., Brotzman Jr. R.W., Nanophase Technologies, US

Modern skin care formulations must meet high standards of efficacy, skin compatibility and aesthetic appeal. The performance of a cosmetic product is related to the entire formulation and an optimal galenic formulation that incorporates a [...]

The Impact of Nano-Materials on UV-Protective Coatings

Cayton R.H., Sawitowski T., Nanophase Technologies Corporation, US

UV-protective, nanocomposite coatings are made by embedding nanocrystalline zinc oxide particles in a polymer matrix. The benefits accrued by incorporating nanoparticles into a polymer matrix become economically driven when several advantageous properties are obtained simultaneously, [...]

Physicochemical Characterization of Nanosize Zinc Oxide and Titanium Dioxide used as UVR Sunscreen Agents in Cosmetic Formulations

Morfesis A., Fairhurst D., Malvern Instruments, Inc., US

The physical (particulate) sunscreen agents, ZnO and TiO2, are increasingly used to provide UV protection in a wide variety of cosmetic and personal care products. The particle size distribution (PSD) of the ZnO and TiO2 [...]
