A new thin layer chromatographic system for the analysis of some commercially available mosquito repellents.

Use of mosquito repellents is a popular way of avoiding mosquito bites. These repellents are quite effective, but can be toxic when misused. These substances are periodically involved in accidental, homicidal and suicidal poisoning cases. The study being presented deals with thin layer chromatographic (TLC) analysis of six samples of different brands of liquid mosquito repellents available in the local markets of India. The results reveal a discernible separation of the components of the selected samples. This could help forensic toxicologists in the quick and economical analysis of samples of mosquito repellents.
