A gas chromatography, using water-vapor as a carrier gas, was investigated for the determination of water-soluble solvents in liquid detergents.
These solvents were separated and determined on porous polymer beads columns, Porapak Q or Tenax GC, and quantitatively recovered from standard detergent in the range of useful formulation.
The recoveries of these solvents were as follows ;
Methyl alcohol : 102.3% Butyl carbitol : 103.3%
Ethyl alcohol : 101.7% Monoethanolamine : 101.3%
Isopropyl alcohol : 100.2% Diethanolamine : 100.9%
Propylene glycol : 100.6% Triethanolamine : 102.4%
Butyl cellosolve : 98.3%
These results were obtained with good accuracy.
This method is applicable to a rapid determination of water-soluble solvent in liquid detergent.
