    Sounds like a detergent. Structually it's bezene sulfonate (-SOOOH) with a dodecyl group (12-C hydrocarbon) substitued somewhere. React it with a sodium base NaB, it forms a sodium sulfonate salt which looks very much like a commercial detergent. The Na+SOOO- end is ionic in character and interacts with water; the hydrocarbon end is very nonpolar and can mix with oils. It acts as kind of intermediate between the oil and water, allowing them to mix (surfactant).

    I found a similar "TEA-dodecylbenzenesulfonate" in my shampoo, it's the same thing substituting TEA=tetraethylammonium (Et4N+) (I think?) for sodium.
