As mentioned, TiO2 is perhaps the most common white pigment and is used in all kinds of things from candy to toothpaste to cosmetics. We eat a lot of it, and it's generally recognized as safe in the US (but not the EU!).
Si02 is just silica/quartz, and is the most common type of sand. It's usually an anti-caking agent but... it's sand. You are almost certainly getting some SiO2 any time you eat a vegetable. It is also generally recognized as safe.
- dunham 4y agoThe title says nano-particles. Is this nano-sand any different from the sand you find on a carrot?
- hammock 4y agoAbsolutely it is different. They mill the silica very finely and then filter out only the nanoparticles for use
- kevin_thibedeau 4y agoSilt is basically naturally milled sand. There isn't anything exotic about it.
- hammock 4y agoDo you eat or breathe a lot of silt? If you did, you'd probably get sick. Silicosis is a terrible and terribly common occupational ailment. It's the size of the particle that matters more than what it's made of
- zdragnar 4y agoThe sickness is due to how the particles interact with the lining of your lungs, and breathing in enough to get ill effects will be much more than you consume through food over a short period. There may be longer term effects, but I'd imagine we would have identified more of them by now, considering how severely dangerous silicosis is.
