Description

Propyl Paraben Sulfate is a specialized organic sulfate ester derivative of propyl paraben, a widely used preservative. This compound is valued for its enhanced water solubility and modified antimicrobial properties compared to its parent ester, making it a versatile intermediate for advanced formulation chemistry. It is primarily utilized by manufacturers in the pharmaceutical, personal care, and cosmetic industries for developing novel preservative systems and functional ingredients.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs requiring sulfate ester functionalities.
• Personal Care Preservative Booster: Acts as a synergistic component in preservative blends for shampoos, conditioners, and liquid soaps to enhance efficacy against microbes.
• Cosmetic Formulation: Employed in the development of water-based cosmetic products like lotions and creams where improved solubility of paraben derivatives is needed.
• Chemical Synthesis: Serves as a key building block or protecting group reagent in organic synthesis for research and fine chemical production.
• Industrial Biocide Component: Incorporated into formulations for industrial fluids and coatings that require controlled-release antimicrobial action.

Quality Control

Our Propyl Paraben Sulfate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification, assay, and impurity profiling, to ensure it meets precise specifications. A Certificate of Analysis (COA) documenting purity, related substances, and other critical parameters is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and stability.
