Polyoxyethylene Stearate, designated by its CAS number 9004-99-3, is a chemical compound whose significance in various industrial applications stems directly from its well-defined chemical and physical properties. A deep understanding of these attributes is crucial for chemists and product developers aiming to leverage its full potential. The chemical formula for Polyoxyethylene Stearate is C34H70O9, indicating its composition derived from stearic acid and ethylene oxide.

Physically, Polyoxyethylene Stearate typically presents as a white waxy solid. This characteristic appearance is a key identifier for quality control. Its solubility profile is also noteworthy; it readily dissolves in various organic solvents such as isopropyl alcohol, mineral oil, and butyl stearate, while also being effectively dispersed in water. This dual capability is what makes it an excellent emulsifier, bridging the gap between immiscible liquids. Exploring the precise solubility and dispersion characteristics is vital when incorporating Polyoxyethylene Stearate into complex formulations.

The purity standard of Polyoxyethylene Stearate, often specified as 99% minimum, is a critical factor for its performance in sensitive applications like pharmaceuticals and high-performance lubricants. Impurities can affect emulsification efficiency, stability, and safety profiles. Manufacturers seeking to buy Polyoxyethylene Stearate must ensure their suppliers meet these stringent purity requirements. NINGBO INNO PHARMCHEM CO.,LTD. places a strong emphasis on maintaining high purity levels for their Polyoxyethylene Stearate products.

The melting point of Polyoxyethylene Stearate typically falls around 47°C, and its flash point is around 39°C. These properties influence its handling, storage, and processing conditions. For instance, understanding the flash point is important for safety protocols during manufacturing and transportation. The pH of Polyoxyethylene Stearate formulations usually ranges between 5.0 and 7.0, indicating a near-neutral characteristic that is often desirable in cosmetic and pharmaceutical applications.

The industrial significance of Polyoxyethylene Stearate is vast. Its role as an emulsifier in lubricants enhances the stability and performance of these essential industrial fluids. In cosmetics, it contributes to the texture and stability of creams and lotions, while in pharmaceuticals, it acts as a reliable excipient. The consistent quality and reliable supply of Polyoxyethylene Stearate are therefore critical for businesses operating in these sectors. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-quality Polyoxyethylene Stearate that meets these demanding industry needs, ensuring that its chemical properties translate into superior product performance for their clients.
