Propyl Paraben Sodium: Essential Preservative for Global Industries

Introduction to Propyl Paraben Sodium


Propyl Paraben Sodium, also known by its chemical name Sodium Propyl P-Hydroxybenzoate, is a highly effective and widely utilized preservative. Identified by its CAS number 35285-69-9, this compound is the sodium salt of Propyl Paraben. It presents as a white crystalline powder, making it a convenient ingredient for various formulations. Its primary functions are rooted in its potent antiseptic and preservative properties, crucial for inhibiting microbial growth and extending the shelf life of products across multiple sectors.

The paraben family of preservatives has a long history of safe and effective use. The sodium salt form, such as Propyl Paraben Sodium, offers enhanced water solubility compared to its acid counterpart, which is a significant advantage when incorporating it into aqueous systems common in many consumer and industrial products. This improved solubility ensures easier dispersion and homogeneous distribution within the final product, contributing to consistent and reliable preservation.

Functions and Applications


Propyl Paraben Sodium functions primarily by disrupting the cell membranes of microorganisms, particularly molds, yeasts, and bacteria, thereby preventing their proliferation. This broad-spectrum antimicrobial activity makes it an invaluable additive in environments susceptible to microbial contamination.

Its applications span several critical industries:


  • Foodstuff: In the food industry, Propyl Paraben Sodium is employed to protect a wide range of products from spoilage caused by microbial action. This includes preventing the growth of harmful pathogens and spoilage organisms in items such as sauces, dressings, baked goods, and beverages. Its use helps maintain the quality, safety, and appearance of food products over time, reducing waste and ensuring consumer safety.

  • Medicine and Pharmaceuticals: Pharmaceutical formulations, particularly liquid and semi-solid preparations like syrups, suspensions, creams, and ointments, require stringent protection against microbial contamination during manufacturing, storage, and use. Propyl Paraben Sodium provides reliable preservation, maintaining the efficacy and safety of medicinal products throughout their stated shelf life.

  • Cosmetics: The cosmetic industry relies heavily on effective preservatives to protect formulations such as lotions, creams, shampoos, conditioners, makeup, and toiletries from microbial spoilage. These products often contain water and organic ingredients that are ideal breeding grounds for bacteria and fungi. Propyl Paraben Sodium helps ensure the hygienic integrity of cosmetic products, preventing degradation, changes in texture or odor, and potential health risks to users from microbial contaminants.

  • Animal Feed: Microbial spoilage can also affect animal feed, leading to reduced nutritional value, palatability issues, and the potential production of mycotoxins. Propyl Paraben Sodium serves as an effective preservative in animal feed formulations, safeguarding the quality and safety of feed and, by extension, the health of livestock.

The versatility of Propyl Paraben Sodium across these diverse applications underscores its importance as a foundational ingredient in modern preservation strategies. Its efficacy at relatively low concentrations, combined with its stability under typical storage conditions, contributes to its widespread adoption.

Quality and Standards


Ensuring the quality and purity of Propyl Paraben Sodium is paramount, especially given its use in sensitive applications like food, pharmaceuticals, and cosmetics. High-quality Propyl Paraben Sodium conforms to rigorous international pharmacopoeial standards, such as BP (British Pharmacopoeia), USP (United States Pharmacopeia), and EP (European Pharmacopoeia). Adherence to these standards guarantees that the product meets specific criteria for purity, identity, and performance.

Typical quality specifications include:
Appearance: White Crystalline Powder
Identification: Meets the requirements
Clarity and color of solution: Clear and transparent
pH: 9.5 ~ 10.5
Sulfate: ≤ 0.03%
Related Substances: Meets the requirements
Moisture: ≤ 5.0%
Chloride: ≤ 350ppm
Content of Arsenic: ≤ 3ppm
Content of Lead: ≤ 5ppm
Content of Mercury: ≤ 1ppm
Assay (on dry base): 99.0 ~ 104.0%
Standard: BP2008/USP32/EP6

These specifications are vital for confirming the product's suitability for demanding applications and ensuring batch-to-batch consistency. Robust quality control testing is performed on each lot to verify compliance with these strict parameters, providing customers with confidence in the material they receive.
