Titanium dioxide (TiO2) is widely used in a variety of products including cosmetics. TiO2 in its nanoparticle form (nano‐TiO2) is now the only form used as an ultraviolet (UV) filter in sunscreens, but also in some day creams, foundations and lip balms. While its efficacy as a UV filter is proven in the prevention of skin cancers and sunburns, some concerns have been raised about its safety. Indeed, considering its small size, nano‐TiO2 is suspected to penetrate dermal, respiratory or… 

Toxicity Evaluation of TiO2 Nanoparticles on the 3D Skin Model: A Systematic Review

The 3D skin model has shown to be promising to evaluate the toxicity of TiO2 NPs, and the possible efforts that should be done in order to avoid interference of NPs with biological assays applied in 3D in vitro culture are focused on.

Due to nanotechnology's advancement, the application of nanomaterials in commercial products, including in sunscreens, has been increased rapidly. Physical sunscreens employ Titanium dioxide (TiO2)

Morphology-dependent titanium dioxide nanoparticle-induced keratinocyte toxicity and exacerbation of allergic contact dermatitis.

After a 24-hour exposure, there were no differences in keratinocyte cytotoxicity; however, Mn-doped TiO2 nanoparticles induced significant in vitro ROS generation and in vivo skin swelling responses in a model of allergic contact dermatitis.

Evaluation of potential eye or skin irritation/corrosion in rabbit exposed to TiO2 photocatalyst (GST)

New TiO2 powder, GST was considered to be no potential effects (irritation/corrosion), penetration or distribution in the local lesions (eye, skin) and the treatment-related effect was not observed in histopathology.

Nanosystems in Cosmetic Products: A Brief Overview of Functional, Market, Regulatory and Safety Concerns

The poor dermal permeation of nanomaterials generally limits their potential toxic effects, which should be mainly ascribed to unwanted or accidental exposure routes, and the main safety concerns arise from the European context.

Behaviour of Titanium Dioxide Particles in Artificial Body Fluids and Human Blood Plasma

This work exposed TiO2 particles of rutile, anatase, and their commercial mixture to various environments, including simulated gastric fluids and human blood plasma, and media used in in vitro experiments, and observed the impact of the absence or presence of chosen enzymes.

Nanoparticles: Excellent Materials Yet Dangerous When They Become Airborne

Since the rise and rapid development of nanoscale science and technology in the late 1980s, nanomaterials have been widely used in many areas including medicine, electronic products, crafts,

Rethinking Nano-TiO2 Safety: Overview of Toxic Effects in Humans and Aquatic Animals.

Bibliometric analysis reveals two major research hot spots including the molecular mechanisms of toxicity of nano-TiO2 and the combined effects of nano’s use in consumer products and other environmental factors such as light and pH.

Application of Selected Nanomaterials and Ozone in Modern Clinical Dentistry

This review is an attempt to summarize current research on ozone, titanium dioxide (TiO2), silver (Ag), copper oxide CuO and platinum (Pt) nanoparticles (NPs) and their applications in dentistry.

Titanium dioxide nanoparticles in sunscreen penetrate the skin into viable layers of the epidermis: a clinical approach

Investigating whether TiO2 nanoparticles in a commercial sunscreen could penetrate intact or sunburned skin in a real-life scenario with UVB exposure and standardized sunscreen applications on human volunteers found no evidence of skin penetration.

Lack of significant dermal penetration of titanium dioxide from sunscreen formulations containing nano- and submicron-size TiO2 particles.

Findings indicate that there is no significant penetration of TiO(2) nanoparticles through the intact normal epidermis of minipigs treated with sunscreens containing TiO (2).

Effects of titanium dioxide nanoparticles on human keratinocytes

Overall, an increase in apoptosis is reported, which may be caspase 8/Fas-dependent, and that the H2TiO7 nanoparticles, despite their smaller particle size, had no significant enhanced effect on HaCaT cells as compared to Fine and Ultrafine forms of TiO2.

Assessment of the in vitro dermal irritation potential of cerium, silver, and titanium nanoparticles in a human skin equivalent model

The stratum corneum of the HSEM may limit penetration of metal nanoparticles to induce toxicity, and these particles were not dermal irritants under the conditions used in this study.

Subchronic exposure of titanium dioxide nanoparticles to hairless rat skin

The influence of subchronic exposure of TiO2 is not significant and titanium contents in several organs were determined using inductively coupled plasma mass spectroscopy and transmission electron microscopy with energy‐dispersive X‐ray spectrometry (EDX).

Penetration of Titanium Dioxide Nanoparticles through Slightly Damaged Skin in Vitro and in vivo

The skin penetration rates of TiO2-NPs through slightly damaged skin and intact skin in vitro and vivo were lower than the rate of free 125I in the TiO3NPs solution, which suggested that the Ti O2- NPs should be safe when it was applied and contacted with skin.

Lack of promoting effect of titanium dioxide particles on chemically-induced skin carcinogenesis in rats and mice.

Treatment with sTiO(2) or ncTiO (2) did not promote skin carcinogenesis in mice or rats, probably due to lack of penetration through the epidermis.

Sunscreens with Titanium Dioxide (TiO2) Nano-Particles: A Societal Experiment

It is argued that the marketing of this nano-sized TiO2 nanomaterial in UV protective cosmetics is ethically undesirable, since it violates four reasonable moral conditions for societal experimentation.

Route-dependent systemic and local immune effects following exposure to solutions prepared from titanium dioxide nanoparticles

The results demonstrate that immune effects of nano-TiO2 exposure are route-of-exposure dependent, and suggest that irritancy and/or potential hypersensitivity responses may occur following parenteral exposure or dermal administration of nanoparticle titanium dioxide to compromised skin.

Stratum Corneum Is an Effective Barrier to TiO2 and ZnO Nanoparticle Percutaneous Absorption

TiO2 or ZnO nanoparticles are absent or their levels are too low to be tested under the stratum corneum in human viable epidermal layers, therefore, significant penetration towards the underlying keratinocytes is unlikely.
