Structure
Material
Prepared Mixture of Potassium Chloride, Magnesium Sulfate and Calcium Lactate is a natural complex material rather than a single molecule, so it has no one structure. FEMA lists it as Prepared Mixture of Potassium Chloride, Magnesium Sulfate and Calcium Lactate.
Identity
Also known as: Potassium, K element, Atomic potassium, Potassium hyperkalemia, MeSH ID: D011188, potassium, kalium, potassium, metal, potassium metal, potassium, elemental, potassium (nos), k.
Can Prepared Mixture of Potassium Chloride, Magnesium Sulfate and Calcium Lactate be labeled natural?
Nature makes Prepared Mixture of Potassium Chloride, Magnesium Sulfate and Calcium Lactate, which is why the US label turns on process. A natural route gives natural flavor; synthesis gives artificial Prepared Mixture of Potassium Chloride, Magnesium Sulfate and Calcium Lactate, same molecule. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic Prepared Mixture of Potassium Chloride, Magnesium Sulfate and Calcium Lactate identical-to-natural.
- United States
- Natural or artificial, by process
- European Union and UK
- Natural only from natural material
- Mercosur and Mexico
- Natural or identical-to-natural
How each market defines the classes: natural vs artificial flavor under 21 CFR 101.22.
Regulatory status, with citations
United States
Prepared Mixture of Potassium Chloride, Magnesium Sulfate and Calcium Lactate is FEMA GRAS under FEMA number 5013. It is cited in the Code of Federal Regulations at 21 CFR 172.515.
European Union and United Kingdom
No EU FL number is on file for Prepared Mixture of Potassium Chloride, Magnesium Sulfate and Calcium Lactate. That is not a finding either way. The Union List covers defined flavouring substances, so natural complex materials are handled as flavouring preparations under Parts B to F and never receive a number, and substances used as additives sit under Regulation 1333/2008 instead. Confirm the position before EU or UK use.
JECFA (WHO / FAO)
Prepared Mixture of Potassium Chloride, Magnesium Sulfate and Calcium Lactate has not been evaluated by JECFA as a flavouring agent, or no evaluation is on file.
Other US flags
Not on the California Proposition 65 list.
