DESCRIPTION
E343 Magnesium Phosphates are a group of magnesium salts of phosphoric acid, and E343 Magnesium Phosphates are used for anticaking, mineral fortification, and acidity regulation depending on the specific form selected.
E343 Magnesium Phosphates differ in solubility and acidity, and monomagnesium phosphate is more soluble and more acidic, while trimagnesium phosphate is less soluble and more neutral.
E343 Magnesium Phosphates can improve powder flow by reducing moisture-driven clumping, and this is why E343 Magnesium Phosphates are used in dry mixes and powdered foods.
E343 Magnesium Phosphates provide magnesium, and magnesium salts can influence taste and processing behavior, so formulation testing is important to avoid bitterness or chalky mouthfeel at higher dosages.
E343 Magnesium Phosphates can affect clarity and texture in beverages, so selection and dosage must be matched to the product type and desired sensory profile.
E343 Magnesium Phosphates should be used according to applicable food additive regulations and good manufacturing practices for the target market.
E343 Magnesium Phosphates are typically supplied as white powders, and particle size and surface area influence flow properties and reactivity.
E343 Magnesium Phosphates should be stored in tightly closed containers in a cool, dry place to prevent moisture pickup and contamination.
E343 Magnesium Phosphates should be handled with good hygiene and dust control practices during bulk powder processing.
E343 Magnesium phosphates are magnesium salts of phosphoric acid and can exist in different phosphate forms depending on specification and hydration state.

FIRST AID
Inhalation:

Avoid breathing dust during powder handling.
Skin Contact:
Wash with soap and water after contact.
Remove contaminated clothing and wash before reuse.
Seek medical advice if irritation develops or persists.

Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists.
Ingestion:
Rinse mouth with water.
Seek medical attention if discomfort occurs or if a large amount is swallowed.
Never give anything by mouth to an unconscious person.
Note to Physicians:
Treat symptomatically.
No specific antidote is required.
Provide supportive care as needed.
HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid generating dust and avoid inhalation of fine powder.
Maintain good hygiene and clean-up practices in handling areas.
Ventilation:
Use general ventilation for normal handling.
Use local exhaust where dust may be generated during powder transfer.
Minimize airborne particulate accumulation in enclosed areas.
Storage:
Store in tightly closed containers in a cool, dry place.
Protect from moisture to prevent caking and maintain free-flowing behavior.
Keep containers properly labeled and protected from contamination.
Spill and Leak Procedures:
Sweep up spilled powder and avoid dust generation.
Collect into suitable containers for reuse or disposal according to local regulations.
Clean residues with water if needed and dry the area to prevent slip hazards.
Handling Precautions:
Select the correct phosphate type because E343 Magnesium Phosphates range from more soluble acidic salts to low-solubility anticaking and fortification salts.
Evaluate sensory and stability impact because magnesium phosphate choice affects solubility, turbidity, and mouthfeel in beverages and powders.
Confirm regulatory permission and maximum use levels because phosphate limits vary by market and product category.
