Titanium Dioxide in Sunscreen
نویسندگان
چکیده
Titanium dioxide has been used in various industrial and cosmetic applications due to its unique elemental properties. This substance has a refractive index higher than most other compounds (n = 2.6142, in comparison to water at 20°C n = 1.33). This allows titanium dioxide to have an iridescent and bright quality. It has been used in the cosmetics industry for “whitening” and “thickening” in multiple make-up brands. As titanium dioxide has the ability to greatly absorb UV light, it has been used as a physical sunscreen for many years. Over time, newer formulations, including “nanoparticle” formulations, have been marketed for ease of consumer use. We aim to discuss the evolution of titanium dioxide in sunscreens over time, discuss its mechanisms of actions, and comment on the efficacy and safety of these products.

The use of sunscreens should also be recommended in order to work against all kind of ultarviolet (UV)-induced skin damage such as photoallergies, skin wrinkles, sunburn or even skin cancer. Sunscreens contain chemical filters (organic absorb regularly UVB radiation) and physical filters (e.g., TiO2 and ZnO). The second group has been said to reflect and scatter UVB and UVA radiation. TiO2 is ...

Formulation and characterization of sunscreen creams with synergistic efficacy on SPF by combination of UV filters
Article history: Received on: 06/07/2013 Accepted on: 19/07/2013 Available online: 30/08/2013 The objective of this study was to develop sunscreen cream formulations with high sun protection factor (SPF) and satisfied characteristics. The actives were anisotriazine (an organic UV filter) and titanium dioxide (an inorganic UV filter). Two optimal cream bases selected from several preliminary for...
متن کاملMeasurement of Titanium Dioxide Nanoparticles in Sunscreen using Single Particle ICP-MS
Titanium dioxide (TiO2) nanoparticles are commonly used in sunscreens as part of the formulation to block the sun’s harmful UV rays. As the use of nanoparticles in consumer products has increased, concern has risen as to the health and environmental effects of nanoparticles. Since sunscreens contact skin and wash off in water, the TiO2 nanoparticles can find their way into biological and enviro...
متن کاملThe influences of nanoscale titanium dioxide particle size and crystal structure on light absorbance
Nanoscale titanium dioxide is an important physical sun-block material and is widely used in sunscreen. In our test, the influences of the particle size and crystal structure on light absorbance were examined. The experiment shows that the absorbance (Abs) of nanoscale titanium dioxide in UV-ray district is much higher than it in visible light district under the same concentration (0.04 g/L). T...
