Factory Supply Propyl Paraben Sodium with CAS number 35285-69-9 is a widely used chemical compound. The chemical formula of Propyl Paraben Sodium is C₁₀H₁₁NaO₃. It appears as a white crystalline powder. It has good solubility in water, which makes it easy to incorporate into various formulations. The melting point of this compound is around 110 - 112°C. It has a characteristic chemical odor, but it is generally used in concentrations where the odor is not overly noticeable in the final product. The pH value of a 1% aqueous solution of Propyl Paraben Sodium is around 9 - 10.5. This product is typically available in different packaging sizes according to customer requirements, such as 25kg drums or 1kg bags for smaller - scale users.
Propyl Paraben Sodium is mainly used as a preservative in a variety of industries. In the cosmetic industry, it is added to products such as creams, lotions, shampoos, and makeup products. It helps prevent the growth of bacteria, fungi, and yeast, thereby extending the shelf - life of these products. This ensures that cosmetic products remain safe and effective for consumers over a longer period. In the food industry, it can be used as a preservative in some food products, especially those with a high water content, like sauces and dressings. By inhibiting the growth of microorganisms, it helps maintain the quality and safety of the food. In the pharmaceutical industry, it is used in some topical and oral medications. It ensures the sterility of the pharmaceutical formulations and prevents the degradation of active ingredients, which is crucial for the effectiveness of the drugs.
When using Factory Supply Propyl Paraben Sodium, it is important to follow certain guidelines. For cosmetic formulations, first, prepare the base of the product (such as the cream or lotion base). The recommended concentration of Propyl Paraben Sodium in cosmetic products is usually between 0.1% - 0.3%. Weigh the appropriate amount of Propyl Paraben Sodium according to the total weight of the formulation and add it to the base while the base is in a liquid state and under gentle stirring. Make sure it is evenly dispersed throughout the base. In the food industry, it should be added during the processing stage. Calculate the required amount based on the legal limits and the specific requirements of the food product. Dissolve the Propyl Paraben Sodium in a small amount of water before adding it to the food mixture to ensure uniform distribution. In pharmaceutical applications, strict compliance with Good Manufacturing Practices (GMP) is necessary. The concentration used is determined by the specific drug formulation and regulatory requirements. It is often added during the blending process of the active and inactive ingredients.
Case 1: A cosmetic company was facing a problem with the spoilage of their popular moisturizing lotion. After conducting tests, they found that the presence of bacteria and fungi in the product was causing it to go bad quickly. They decided to add Propyl Paraben Sodium to their formulation at a concentration of 0.2%. After the addition, they conducted shelf - life studies. They found that the lotion remained stable and free from microbial growth for over a year, compared to the previous shelf - life of only a few months. This led to a significant reduction in product returns and an increase in customer satisfaction.
Case 2: A food manufacturer that produced a line of salad dressings was experiencing issues with the development of off - flavors and mold growth in their products. They incorporated Propyl Paraben Sodium into their dressing recipes at a concentration within the legal limits. The result was that the dressings maintained their original flavor and texture for a much longer time during storage and transportation. This allowed the company to expand its market reach as the products could be shipped to more distant locations without spoilage concerns.
Case 3: A pharmaceutical company was developing a topical anti - inflammatory cream. To ensure the stability and sterility of the active ingredients, they added Propyl Paraben Sodium to the cream formulation. Through accelerated stability tests, they found that the cream retained its potency and remained free from microbial contamination for the entire shelf - life of the product, which was two years as per regulatory requirements.
