Silane-coated Titanium Dioxide Dispersion for Protection and Skin Feel

Croda combines UV protection with a desirable skin feel in its latest launch.

Inorganic, Broad-spectrum UV Filter

BASF has introduced an inorganic, broad-spectrum UV filter based on zinc oxide.

Water-based, High-UVA Titanium Dioxide Dispersion for Natural UV Protection and Added Formulation Benefits

A novel titanium dioxide (TiO2) showing enhanced UVA protection was previously found to be effective as the sole active ingredient in sun care formulations, achieving levels of UVA protection recommended by the European Commission. Here, a water-based dispersion of the same TiO2 particles is described that offers a high level of UVA protection in sun care products with excellent formulation flexibility.

Ingredient Profile—Ethylhexyl Methoxycinnamate

Ethylhexyl methoxycinnamate (EHMC) is among the most frequently used organic ultraviolet (UV) filters, known primarily for its role as an active ingredient in sunscreen products.

Micronized Inorganic UV Filters

TRI-K Industries Inc. has introduced a line of micronized titanium dioxide and zinc oxide inorganic UV filters.

Researchers Investigate Bacteria Pigment as a UV Filter Without Allergens

Scientists at the University of Gothenburg and Chalmers University of Technology have found a bacterial component that serves as a UV filter without causing contact allergies.

Water-based, Broad Spectrum, Titanium Dioxide Dispersion

Croda has added a water-based titanium dioxide dispersion to its Solaveil range.

Ingredient Profile: Titanium Dioxide

While TiO2 is often incorporated as a colorant and an opacifier in cosmetics and personal care products, its most important applications are as a sunscreen active and as a component of specialty pigments for color cosmetics.

A Melanin Derivative to Shield the Skin from High Energy Visible Light

High energy visible (HEV) light recently has been suspected of causing as much damage as UVA and UVB combined. Thus, the present paper describes a fractionated melanin tailored to absorb light in the visibile 400–500 nm range. In addition, because the material exhibits color, the authors focus on formulation techniques to incorporate it into semi-solid formulations.

Au Naturale Nanoparticle Sun Protection

In 1876, Charles Darwin observed the secretion of yellow matter from the rootlets of ivy. Little was known about the material until 2008, when Mingjun Zhang, PhD, an associate professor of biomedical engineering at the University of Tennessee, and his research team found nanoparticles in the yellow matter.

Silicon Microspheres as UV, Visible and Infrared Filters for Cosmetics

Silicon microspheres are described as UV, visible and infrared (IR) radiation filters. Parameters of these spheres including shape, smoothness, refractive index and size are examined for their potential benefits in cosmetic formulations. Finally, the ability of the spheres to block IR radiation is evaluated for thermo-regulatory effects.

Meeting the UVA Challenge: Inorganic-only Sun Protection

The production of a range of titanium dioxide-based dispersions is explored to provide enhanced UVA protection, in comparison with ultrafine titanium dioxide. Formulations containing these dispersions as the only active are shown to achieve a UVA protection factor that is 1/3 of the labeled SPF value, thus meeting European Commission recommendations.
