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.

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.

Micron-sized Zinc Oxide Dispersion for Transparent High SPF Formula

Regulatory bodies require quantifiable, photostable UVA protection for sunscreens and while zinc oxide provides an effective option, historically, its white appearance on skin has limited its acceptance. Therefore, in the present article the authors explore a micron-sized zinc oxide dispersion technology to enable the formulation of transparent yet full spectrum sunscreen formulas.

Singlet Quenching Proves Faster is Better for Photostability

The faster a photostabilizer works, the fewer opportunities for destructive chemical reactions. Here, the author describes a new photostabilizer, ethylhexyl methoxycrylene, which acts by quenching the singlet excited state of UV filters. The data shows how this material sets a new standard for the photostabilization of avobenzone, even in the presence of octyl methoxycinnamate.

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.
