CIPAC 36 Chlorhexidine digluconate determination: Analytical approach and significance
Chlorhexidine digluconate (CHX) is a biocide that, due to its strong antimicrobial and antiseptic properties, is widely used in both medical and hygiene products. Due to its effectiveness, particularly against gram-positive and gram-negative bacteria, this active ingredient is used in disinfectant solutions, surgical antiseptics, and oral care products. The correct determination of the active ingredient quantity in such products is, however, crucial for effectiveness and safety.
Determination of chlorhexidine digluconate: Why is this important?
The effectiveness of a biocidal product depends on the correct concentration of the active ingredient. Too low dosages make the product ineffective, while too high dosages can harm human health. For this reason, a determination of chlorhexidine digluconate is carried out as part of product quality control. This analysis:
- confirms the active ingredient content of the product,
- ensures compliance with regulations and standards, and
- guarantees the effectiveness and safety of the product.
IJPSR (2015) Method: Determination of chlorhexidine digluconate by HPLC
The methodology published in 2015 in the International Journal of Pharmaceutical Sciences and Research (IJPSR, Volume 6, Issue 12) describes an analytical determination method based on high-performance liquid chromatography (HPLC). This method was developed to determine the chlorhexidine content in CHX-containing biocidal solutions or products with high accuracy.
Analysis principle and basic properties:
✔️ Use of an HPLC-UV/DAD detector system
✔️ CHX standards are prepared in a certain concentration range
✔️ The content is quantitatively measured with linear calibration curves
✔️ The dissolved samples are separated with a suitable mobile phase
✔️ UV detection at a wavelength of 254 nm
✔️ The data are evaluated during the analysis using software (e.g., Empower)
This type of chromatographic methods ensures high accuracy, repeatability, and precision and is therefore preferred in quality control laboratories for routine analyses.
Application areas of CHX analysis methods
This type of determination methods is not only applied theoretically in the laboratory but also used daily in the quality control of real products. In particular:
- Detection of active ingredients in biocidal solutions
- Quality testing after the production of disinfectants
- Control processes by manufacturers and supervisory authorities
- Use as a reference method in accredited laboratories
Analytical accuracy for quality and safety
Chlorhexidine digluconate is a strong antiseptic, but the application of standardized analytical methods is required to correctly demonstrate this effectiveness in products. The IJPSR-2015 methodology enables the rapid and reliable measurement of CHX in biocidal products by means of HPLC-based SHG determination.
Such analyses are important for both regulatory compliance and human health.
