Surfactants and Surface Active Agents analysis and testing for Pharmaceuticals and Industrial Products.

Intertek laboratories are able to detection and quantification of low levels of surfactants in solid and liquid products and formulations requires a range of analytical technologies. Intertek offers a wide range of analysis capabilities with package options appropriate to surface active agents in pharmaceutical and industrial applications. In addition to surfactants, Intertek offers specialist know-how in analysis of antifoams and dispersants typically used in these products. Applications include support to manufacture of existing products, FDA submissions for new product introduction and competitor product analysis. Intertek can assist customers determine the presence of surfactants which are restricted in their application or use by the Detergent Directive or upcoming REACH legislation.

Surfactants, antifoams and dispersing agents analysed include:

  • Non-ionic surfactants: alkoxylate based on PEG’s and PPG’s (including nonyl phenol ethoxylates NPE)
  • Anionic surfactants: alkyl sulphates, alkyl benzene sulphonates, phosphate esters
  • Cationic surfactants: quaternary ammonium compounds
  • Amphoteric surfactants: CAPB
  • Antifoams: silicone copolymers and acetylenic diols
  • Disperants with a variety of structures and functionalities
  • Separation and characterisation and quantification of mixed surfactant systems in formulated products

Surfactant analytical techniques available include:

  • Comprehensive classical chemistry analysis, titrations, colorimetry
  • MALDI-TOF MS, Matrix Assisted Laser Desorption Ionization Time-of-flight Mass Spectrometry
  • Other Mass Spectrometry instrumentation e.g. LCMS, HRMS
  • Solution state NMR
  • Chromatography, including HPLC and Gel Permeation Chromatography (GPC) with UV, ELSD, RI detection, GC for chain length distribution
  • Surface Tension measurement
  • Product Identification

Intertek Laboratories have complementary expertise in the detection of surfactants in a wide range of home and personal care products.
