Water-based, High-UVA Titanium Dioxide Dispersion for Natural UV Protection and Added Formulation Benefits
By: Alice Miles, Michael Hilditch, Robert M. Sayer…
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.

While the introduction of fluoride remarkably increased the life expectancy of natural teeth, two oral care problems have since emerged: tooth sensitivity and dental erosion. This article describes approaches to these problems and discusses the challenge of simultaneously maintaining fluoride efficacy in multi-benefit toothpaste formulations.

Recent work indicates that the biomarker progerin, in conjunction with dysfunctioning telomeres, triggers cellular senescence. In response, trifluoroacetyl-tripeptide-2, a synthetic tripeptide, was developed to decrease progerin production, thereby regulating biological mechanisms involved in the aging process and reducing the cosmetic effects of aging, which are explored here.
