Prof Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), said: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive . A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body”.

Macromolecular oxidation was detected in proteins by the colorimetric measurement of Advanced Oxidation Protein Products (AOPP) and in lipids by the colorimetric quantification of malondialdehyde (MDA). Standard curves were run with chloramine-T and 1,1,3,3 tetraethoxypropane (TEP) for AOPP and MDA methods, respectively [29][30][31]. Values were normalized to initial protein content in samples, measured with Bradford reagent [32]. The standard deviation of at least six measures was calculated and p-value < 0.05 were considered significant.

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

Overall, titanium dioxide is an incredibly versatile pigment with a wide range of applications. Whether you are looking for a durable white pigment for outdoor use, a bright and opaque pigment for paper and plastics, or a specialized grade for a specific application, there is likely a type of titanium dioxide that will meet your needs. Its unique properties and flexibility make it an indispensable ingredient in a wide range of products that we use every day.

  • Beyond their visual appeal, hidden grid ceiling tiles also offer numerous functional advantages. One significant benefit is improved acoustics. These tiles can be designed to reduce noise pollution, which is particularly useful in open office environments, conference rooms, and other communal spaces. By selecting acoustic performance tiles, designers can create a quieter, more focused atmosphere that enhances productivity and comfort.

  • Proper installation of cross tees is crucial for the overall performance of the suspended ceiling. When installing, it is vital to ensure that the main tees are level and that the cross tees are evenly spaced. Typically, cross tees are installed perpendicular to the main tees and are secured into the clips or sockets provided. For larger spaces, additional support may be required to maintain the stability of the grid system.


  • Furthermore, a ceiling price can affect the quality of the T runner itself. With price constraints in place, manufacturers may cut costs to maintain profitability, potentially compromising the quality and durability of the product. This dynamic could be particularly concerning in a market that values performance and longevity in athletic gear. If consumers begin to perceive the T runner as inferior due to quality issues arising from the price ceiling, it could damage the brand's reputation and reduce consumer satisfaction.

  • Cut a piece of plywood or drywall to fit inside the frame snugly. If you are using drywall, ensure the edges are painted or sealed to prevent moisture damage. Sand the edges of the panel to ensure a smooth fit and prevent any accidental injury.


  • 2. Space Efficiency Instead of compromising valuable floor space with permanent access points, trap doors offer a discreet solution. They can be strategically placed to maintain the functionality and aesthetics of spaces, particularly in residential and commercial settings.

  • 1. Ease of Access One of the primary advantages of a 600x600 access panel is its ability to grant quick access to the ceiling void. This helps maintenance teams conduct repairs or inspections without causing significant disruptions to the environment below. Instead of cutting into the ceiling or removing tiles, technicians can simply open the access panel and resolve issues efficiently.

  • 2. Measuring and Cutting the Opening After marking the dimensions of the hatch, carefully cut the plasterboard to create an opening that fits the hatch’s frame. Ensure any electrical wiring or plumbing within the ceiling is taken into account to avoid damage.


  • The grid system itself is typically made from lightweight metal or aluminum, which provides durability without adding excessive weight to the ceiling. Most grids are designed for easy installation and maintenance, allowing for access to plumbing, electrical wiring, and HVAC systems above the ceiling.


  • Cost-Effectiveness


  • Additionally, the design of the hatch should match the existing decor. For residential applications, choose hatches that blend seamlessly with the ceiling’s material and paint. For commercial settings, durability might take precedence, so opting for robust materials that can withstand frequent use and wear is advisable.


  • When planning the installation of fire-rated access panels in drywall ceilings, several factors must be considered. Firstly, the panel must be installed in accordance with the manufacturer’s guidelines and local building codes to ensure that it effectively contributes to the building’s fire-resistance rating. The location of the panel is also critical; it should be positioned strategically to allow easy access to the systems it serves while ensuring that it does not create fire hazards.
