Hypothesis
The authors hypothesized that the determination of fatty acids in soaps could be automated using a continuous flow system.
Conclusion
The automated method for determining fatty acids in soaps is reliable and can improve the efficiency of quality control.
Supporting Evidence
- The method was tested on both AutoAnalyzer and AutoAnalyzer II systems.
- Calibration curves remained stable over 10 days, indicating reliability.
- Results showed that increasing sample rates on the AutoAnalyzer II improved precision.
Takeaway
This study shows a new way to quickly and accurately measure fatty acids in soap using machines, making it easier for factories to check their products.
Methodology
The study involved developing an automated method based on a titration reaction between soap and a quaternary ammonium salt complexed with bromo-cresol green, measured colorimetrically.
Limitations
The method is only reliable for samples with an average molecular weight of fatty acids between 200 and 300.
