Nowadays, gold has made its way into various skincare products such as lotion and cream, as well as skincare treatments such as facial masks. Gold in skincare products are usually in the form of colloidal gold, or more commonly called nanogold. [17] These nanoparticles ranges in size from 5 nm to 400 nm. [18]
Ultrafine TiO 2 is believed to be one of the three most produced nanomaterials, along with silicon dioxide nanoparticles and zinc oxide nanoparticles. [9] [11] [12] It is the second most advertised nanomaterial in consumer products, behind silver nanoparticles. [13] Due to its long use as a commodity chemical, TiO 2 can be considered a "legacy ...
Andrew Maynard, director of Risk Science Center at the University of Michigan, rejected the supposed danger from use of titanium dioxide in food. He says that the titanium dioxide used by Dunkin' Brands and many other food producers is not a new material, and it is not a nanomaterial either. Nanoparticles are typically smaller than 100 ...

In the study, rats that ingested titanium dioxide every day showed signs of a flared-up immune systems and pre-cancerous lesions. (Don’t miss these other 8 cancer-causing foods you should stop ...
Schematic representation of the different stages and routes of the sol–gel technology. In this chemical procedure, a "sol" (a colloidal solution) is formed that then gradually evolves towards the formation of a gel-like diphasic system containing both a liquid phase and solid phase whose morphologies range from discrete particles to continuous polymer networks.
Most applications are "first generation" passive nanomaterials that includes titanium dioxide in sunscreen, cosmetics, surface coatings, [59] and some food products; Carbon allotropes used to produce gecko tape; silver in food packaging, clothing, disinfectants, and household appliances; zinc oxide in sunscreens and cosmetics, surface coatings ...
Titanium dioxide nanoparticles imparts what is known as the self-cleaning effect, which lend useful water-repellant and antibacterial properties to paints and other products. Zinc oxide nanoparticles have been found to have superior UV blocking properties and are widely used in the preparation of sunscreen lotions, [ 171 ] being completely ...
