MSP – Monosodium Phosphate

Product Introduction

MSP – Monosodium Phosphate is a versatile inorganic phosphate compound widely used in food processing, animal nutrition, fermentation technology, and industrial applications. As the most acidic member of the sodium phosphate series, it provides effective acidity adjustment and pH buffering, making it suitable for manufacturing processes that require controlled acidity and stable formulation performance.

Available in anhydrous, monohydrate, and dihydrate forms, Monosodium Phosphate offers high water solubility and flexible application options. In food manufacturing, it functions as an acidity regulator, emulsifier, and moisture-retaining agent. It is also used in dairy processing, beverage production, and fermentation media to support consistent processing conditions.

For feed applications, feed-grade MSP serves as a phosphorus source for poultry and aquatic animal nutrition. Industrial-grade material is used in boiler water treatment, metal surface cleaning, leather processing, electroplating, and other chemical applications.

Wuhan Waking Lion Chemicals Co., Ltd. supplies Monosodium Phosphate in food, feed, and industrial grades, providing different hydrate forms, packaging options, and technical documentation to meet diverse purchasing and production requirements.
