The advantages of infrared and Raman spectroscopy are that they are non-destructive, requires no sample extraction or purification, and directly provide structural information of lipids, fatty acids, proteins etc. In particular, by using attenuated total reflection (ATR)-FT/IR, which is suitable to for surface characterization, oil- and protein-based soil components attached to the same surface of a wet-type artificially soiled fabric can be directly and separately quantified at the same time. In this article, a novel spectroscopic method for quantitative evaluation of detergency using the ATR-FT/IR method is reviewed with introducing some characterization results.
