Propyl Paraben Sodium

Description

Propylparaben sodium is a preservative used in cosmetics, pharmaceuticals, and foods. It is the sodium salt of propylparaben, a chemical ester of p-hydroxybenzoic acid. It acts as an antimicrobial agent, inhibiting the growth of bacteria, molds, and yeasts. It is often preferred for its water solubility, which simplifies its incorporation into formulations without needing heating.
Key characteristics and uses:
Antimicrobial: Sodium propylparaben is a broad-spectrum preservative effective against a range of microorganisms.
Water Soluble: It readily dissolves in cold water, making it easy to add to formulations without requiring heat.
Preservative: Extends the shelf life of products by preventing microbial spoilage.
Cosmetics, Pharmaceuticals, and Foods: Widely used in these industries.
E Number: In food, it is known as E216.
Synergistic Effects: Can enhance the activity of other preservatives when used in combination.
Potential Concerns: While generally considered safe, there are some concerns about potential endocrine disruption and skin irritation.
Metabolism and Excretion: Propylparaben is metabolized in the body and excreted through urine.
