Monosodium Phosphate (MSP) CAS No.7558-80-7

Monosodium Phosphate (MSP) CAS No.7558-80-7

Monosodium Phosphate (MSP) CAS No. 7558-80-7, is an inorganic compound commonly available as a white crystalline powder. It is highly soluble in water and widely used in the food, pharmaceutical, and industrial sectors due to its buffering, sequestrant, and emulsifying properties.

Key Applications of Monosodium Phosphate (MSP) CAS No.7558-80-7

1. Food Industry

In the food industry, MSP is widely applied as a food additive (E339a). It serves as a pH regulator, emulsifier, and nutritional supplement. MSP is often used in dairy products, beverages, baked goods, and processed meats to stabilize quality and extend shelf life.

2. Pharmaceutical Applications

In the pharmaceutical field, Monosodium Phosphate is used as a buffering agent in formulations and laboratory research. It also serves as a component in laxatives and saline solutions, contributing to medical and healthcare applications.

3. Water Treatment

MSP is applied in water treatment systems as a scale inhibitor and corrosion control agent. It helps maintain water quality by preventing scale formation and metal corrosion in pipelines and boilers.

4. Industrial Uses

Beyond food and pharma, Monosodium Phosphate is used in detergents, ceramics, and textile processing. Its dispersing and buffering properties improve industrial processes and product performance.

Frequently Asked Questions (FAQs)

What is Monosodium Phosphate (MSP)?

Monosodium Phosphate (MSP) is a sodium salt of phosphoric acid with the formula NaH₂PO₄ and CAS 7558-80-7, acting as a pH buffer and sequestrant. It’s a white, water-soluble powder used to regulate acidity and stabilize formulations in food and industrial products.

How is MSP used in food processing?

Incorporate MSP at 0.2-0.5% during mixing to adjust pH and emulsify fats; for baking, add to dry ingredients for controlled acidification. Conduct stability tests to optimize dosage for specific recipes.

Is MSP safe for consumption?

Yes, MSP is FDA GRAS and approved by JECFA up to 70 mg/kg phosphorus equivalent in foods, with rapid absorption and no established toxicity at typical usage levels.

What is the shelf life of MSP?

Stored in airtight containers in a cool, dry environment, MSP maintains full activity for 2-3 years, though hygroscopic—monitor for clumping in humid conditions.

Can MSP be blended with other phosphates?

MSP synergizes with disodium phosphate for pH gradients in buffers but may precipitate with excess calcium; it’s compatible in most blends after pilot testing.

Does MSP alter the flavor of products?

MSP’s mild acidity imparts no off-flavors at standard doses, preserving natural tastes in beverages and dairy while enhancing freshness through preservation.

What packaging options are available for MSP?

Options include 25kg polyethylene-lined bags, 50kg fiber drums, and 1000kg supersacks, all designed for moisture protection and compliant with food-grade shipping.
