gravimetric titanium dioxide determination

The prices of lithopone are influenced by several factors, including raw material costs, production capacity, supply and demand dynamics, regional economic conditions, and environmental regulations. Zinc and sulfur, the primary components of lithopone, are subject to fluctuations in their global market prices, which directly impacts the cost of lithopone production. Additionally, stricter environmental norms often lead to increased production costs for manufacturers, affecting the final pricing.

It should also be considered that due to the low pH in the stomach, the increased dissolution of the TiO2 particles may increase its bioavailability and may facilitate the entry of titanium ions into the blood circulation. Despite the relatively large consumption of TiO2 as a food additive, no studies on the effect of pH on its absorption and bioavailability have been found in the literature. This can be attributed to a general belief that TiO2is completely insoluble. However, this is not completely true, as TiO2 particles show a certain degree of solubility.

CSPI’s Chemical Cuisine is the web’s definitive rating of the chemicals used to preserve foods and affect their taste, texture, or appearance. Besides titanium dioxide, the group recommends avoiding artificial sweeteners like aspartame, acesulfame potassium, and sucralose, as well as synthetic food dyes like Yellow 5 and Red 3. CSPI and others have recently asked the Food and Drug Administration to ban the latter dye in foods and ingested drugs because the FDA has already determined that it is a carcinogen unsafe for use in cosmetics.
