One key advantage of these screws is their ability to provide a clean and professional finish. The countersunk head allows for a flush mount, preventing any protrusions that could catch on clothing or cause injury The countersunk head allows for a flush mount, preventing any protrusions that could catch on clothing or cause injury
One notable advantage of wafer head screws is their drive recess, typically designed for an Allen wrench or a Torx driver
- Barium sulfate, chemically represented as BaSO4, is a naturally occurring mineral known as barite. When processed into a superfine form, it possesses an array of benefits that extend beyond its inexpensive nature. Its fine particle size enhances its dispersibility, leading to improved performance in various applications. This superfine variant, despite its 'cheap' label, does not compromise on quality or functionality.

But this is just the tip of the ice berg so many articles & studies are coming out challenging the safety of Titanium Dioxide in our food supply & personal care products.

The element titanium and the compound TiO2 are found around the world, linked to other elements such as iron, in several kinds of rock and mineral sands (including a component of some beach sands). Titanium most commonly occurs as the mineral ilmenite (a titanium-iron oxide mineral) and sometimes as the mineral rutile, a form of TiO2. These inert molecular compounds must be separated through a chemical process to create pure TiO2.
Titanium dioxide (TiO2) is considered as an inert and safe material and has been used in many applications for decades. However, with the development of nanotechnologies TiO2 nanoparticles, with numerous novel and useful properties, are increasingly manufactured and used. Therefore increased human and environmental exposure can be expected, which has put TiO2 nanoparticles under toxicological scrutiny. Mechanistic toxicological studies show that TiO2 nanoparticles predominantly cause adverse effects via induction of oxidative stress resulting in cell damage, genotoxicity, inflammation, immune response etc. The extent and type of damage strongly depends on physical and chemical characteristics of TiO2 nanoparticles, which govern their bioavailability and reactivity. Based on the experimental evidence from animal inhalation studies TiO2 nanoparticles are classified as “possible carcinogenic to humans” by the International Agency for Research on Cancer and as occupational carcinogen by the National Institute for Occupational Safety and Health. The studies on dermal exposure to TiO2 nanoparticles, which is in humans substantial through the use of sunscreens, generally indicate negligible transdermal penetration; however data are needed on long-term exposure and potential adverse effects of photo-oxidation products. Although TiO2 is permitted as an additive (E171) in food and pharmaceutical products we do not have reliable data on its absorption, distribution, excretion and toxicity on oral exposure. TiO2 may also enter environment, and while it exerts low acute toxicity to aquatic organisms, upon long-term exposure it induces a range of sub-lethal effects.
Titanium dioxide helps protect the skin from both UVA and UVB rays. Plus, it’s generally considered to be safe for sensitive skin types. Not only that, but it might also make for sunscreens that are more suitable for children and infants since it’s much less likely to cause stinging compared to chemical sunscreens. And when used in foundations, titanium dioxide can even provide a little extra sun protection on top of your daily SPF.
From dyes to flavorings, many people are becoming increasingly aware of the ingredients in their food.
In a 2020 study published in the Journal of Trace Elements in Medicine and Biology, researchers conducted an in vitro experiment to analyze the effects of TiO2 nanoparticles on a human neuroblastoma (SH-SY5Y) cell line. The scientists evaluated “reactive oxygen species (ROS) generation, apoptosis, cellular antioxidant response, endoplasmic reticulum stress and autophagy.” The results showed that exposure to the nanoparticles “induced ROS generation in a dose dependent manner, with values reaching up to 10 fold those of controls. Nrf2 nuclear localization and autophagy also increased in a dose dependent manner. Apoptosis increased by 4- to 10-fold compared to the control group, depending on the dose employed.”
