Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide:
On November 23, 2022, the General Court of the European Union reversed the conclusion that titanium dioxide was carcinogenic and released a statement (1,2):
“First, the Commission made a manifest error in its assessment of the reliability and acceptability of the study on which the classification was based and, second, it infringed the criterion according to which that classification can relate only to a substance that has the intrinsic property to cause cancer.”
As part of our mission at CRIS we base our safety assessments on the currently available scientific evidence and consider many variables (e.g., study quality, journal of publication, etc.), even if it goes against previous conclusions. Evidence-informed decisions making is critical to ensure that the laws and regulations put into place are for the benefit of the population.
The EU General Court maintains that the scientific evidence presented wasn’t the complete picture for the ingredient, “in the present case, the requirement to base the classification of a carcinogenic substance on reliable and acceptable studies was not satisfied.”
In 2019, EFSA published a statement on the review of the risk related to the exposure to food additive titanium dioxide (E171) performed by the French Agency for Food, Environment and Occupational Health Safety (ANSES). In its statement, EFSA highlighted that the ANSES opinion reiterated the uncertainties and data gaps previously identified by EFSA and did not present findings that invalidated the Authority’s previous conclusions on the safety of titanium dioxide.
- Fire Resistance Many access panels are designed to withstand fire, providing an additional layer of safety in commercial and residential buildings. This is particularly important in compliance with building regulations and codes.

What is PVC Gypsum?
One of the primary reasons for the increasing popularity of exposed ceiling grids is their aesthetic appeal. They contribute to a sense of openness and spaciousness, making rooms feel larger and more airy. The raw, industrial look of the exposed materials can add character and uniqueness to a space, appealing to those who favor contemporary and minimalist designs. Additionally, the visual contrast created by juxtaposing the structural elements with softer furnishings and décor can create an engaging environment that captures attention and encourages interaction.
3. Grid System Quality
Choosing the Right Ceiling Hatch
The primary purpose of ceiling tie wire is to provide stability to suspended ceiling systems. In commercial construction, where ceilings may be loaded with lighting fixtures, air conditioning units, and other installations, ensuring that these elements are securely anchored is crucial. Improperly suspended ceilings can lead to catastrophic failures, posing safety risks to occupants.
In conclusion, the hatch in the ceiling transcends its physical form, encapsulating a world of possibilities. It invites both children and adults to ponder their imaginations, reflect on their lives, and explore the delicate balance between practicality and creativity.
