For any procurement professional or R&D scientist in the pharmaceutical sector, understanding the precise specifications of raw materials is fundamental to ensuring product quality and regulatory compliance. Pharmaceutical Grade Liquid Paraffin (CAS 8042-47-5) is no exception. As a leading manufacturer and supplier, we aim to provide clarity on the critical parameters that define this essential excipient, helping you make informed purchasing decisions. Our commitment is to supply a product that meets the highest industry benchmarks.

Key Specifications for Pharmaceutical Grade Liquid Paraffin

The primary defining characteristic of pharmaceutical grade liquid paraffin is its exceptional purity, typically exceeding 99%. This high level of purity is verified through rigorous testing, ensuring the absence of harmful contaminants. Regulatory bodies such as the USP (United States Pharmacopeia), NF (National Formulary), BP (British Pharmacopoeia), and Ph. Eur. (European Pharmacopoeia) set stringent standards that manufacturers must adhere to. When you buy liquid paraffin, always look for confirmation of compliance with these pharmacopoeias. Beyond purity, other crucial specifications include:

  • Appearance: A clear, colorless, and odorless oily liquid.
  • Viscosity: While varying grades exist, viscosity is a key parameter for formulation performance, influencing spreadability and texture. Manufacturers often provide kinematic viscosity at 40°C.
  • Relative Density: Typically around 0.8617, this indicates the oil's density compared to water.
  • pH Value: A measure of acidity or alkalinity, which should be neutral for pharmaceutical use.
  • Polycyclic Aromatic Hydrocarbon (PAH) Content: This should be extremely low, often specified at ≤0.02%, to ensure safety.
