Cast iron skillets traditionally do not have a synthetic coating. Instead, they are seasoned, which involves coating them in oil and baking them. This process creates a natural, non-stick surface and protects the skillet from rust. Over time, with proper care, this seasoning layer improves, making the skillet naturally non-stick. Some modern cast iron skillets might come pre-seasoned from the manufacturer, saving you the initial seasoning steps. However, it's crucial to maintain this seasoning by avoiding harsh detergents and not over-scrubbing, which can remove this protective layer.
Titanium dioxide (TiO2) was classified as a substance of very high concern (SVHC) by the European Chemicals Agency (ECHA) primarily due to its inhalation risk in powder form causing respiratory tract cancer. This decision, officially effective from February 2020, specifically targets titanium dioxide in powder form containing 1% or more of particles with aerodynamic diameter ≤ 10 μm. The classification underscores the importance of handling precautions and regulatory compliance, especially in industries that manufacture or use this substance in its powder form, such as paints, coatings, and sunscreens. The inclusion in the SVHC list means that titanium dioxide in these specific conditions requires proper risk management measures and communication within the supply chain. However, it's important to note that products containing titanium dioxide are generally considered safe for consumers under normal use conditions.
The Substances of Very High Concern SVHC list of the European Chemicals Agency does not include titanium dioxide. However. titanium dioxide is considered a probable human carcinogen if inhaled in large quantities and is also classified as a second such carcinogen under EU regulations. Although this is not consistent with the SVHCC. However. it emphasizes the importance of safe handling and use.
Arginine is classified as a conditionally essential amino acid, meaning it is generally not indispensable because the body can synthesize it. However, during periods of rapid growth, illness, or stress, endogenous synthesis may not meet the body's demands, making dietary intake necessary. In adults, arginine synthesis is typically sufficient, but in infants or those with certain health conditions, it becomes more essential. The body produces arginine from citrulline, another amino acid, via the urea cycle. Factors like inadequate growth hormone production can also affect arginine synthesis, highlighting its conditional nature depending on physiological states.
