Prof. Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), wrote of the decision: “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.”
Properties of Lithopone 28B301 and 30B311

The invention relates to a production process of an inorganic pigment lithopone, in particular to a method for producing nanometer lithopone by using electrolytic zinc acid leaching residue. Background technique
Analyst Insight
When E171 isn’t combined with other ingredients and administered in water, some studies suggest that under these artificial conditions, E171 may be processed differently in the body resulting in some biological changes in experimental animals that are poorly understood.
The report also covers a detailed analysis of the project economics for setting up a lithopone manufacturing plant. This includes the analysis and detailed understanding of capital expenditure (CapEx), operating expenditure (OpEx), income projections, taxation, depreciation, liquidity analysis, profitability analysis, payback period, NPV, uncertainty analysis, and sensitivity analysis. Furthermore, the report also provides a detailed analysis of the regulatory procedures and approvals, information related to financial assistance, along with a comprehensive list of certifications required for setting up a lithopone manufacturing plant.
