Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
For chemists and product formulators, understanding the precise chemical and physical properties of raw materials is fundamental to successful product development. Potassium 4-aminobenzoate (CAS 138-84-1), a compound vital to both the cosmetic and pharmaceutical industries, possesses a distinct set of characteristics that dictate its application and handling. NINGBO INNO PHARMCHEM CO.,LTD., a reputable manufacturer and supplier, provides essential insights into these properties.
Potassium 4-aminobenzoate, chemically known as Potassium 4-aminobenzoate, presents as a white to off-white crystalline powder. This specific appearance is a key visual indicator of its purity. The compound is highly valued for its solubility, demonstrating good solubility in water (approximately 500 mg/mL) and moderate solubility in ethanol (50 mg/mL). This water solubility is particularly advantageous for formulators, enabling its easy integration into aqueous-based systems commonly found in skincare and pharmaceutical preparations.
The purity of Potassium 4-aminobenzoate is typically specified as ≥98% as determined by High-Performance Liquid Chromatography (HPLC). This high level of purity is crucial for its function as a UV absorber in sunscreens and as a reliable intermediate in pharmaceutical synthesis. Its pH in a 5% aqueous solution typically ranges from 7.5 to 9.0, indicating a mildly alkaline nature. The UV absorption spectrum, with a λmax at 290 nm, confirms its efficacy in the UVB range, a critical factor for sunscreen performance. Furthermore, the compound is stable under recommended storage conditions of 2-8°C in amber glass, desiccated, and boasts a shelf life of 36 months, ensuring its quality over time.
