AI Thread Summary
The discussion centers around the chemical properties and applications of a specific compound, identified by its CAS number 25155-30-0. It is characterized as a sodium sulfonate salt derived from dodecylbenzene sulfonate, which is structurally similar to commercial detergents. The compound features a hydrophilic ionic end and a hydrophobic hydrocarbon tail, enabling it to function as a surfactant that facilitates the mixing of oil and water. It is noted for its physical form, which can be white to light yellow flakes, granules, or powder, and has a solubility of 0.5-1.0 g/100 mL in water at 19°C. The melting point exceeds 300°C, indicating its stability at high temperatures. The discussion also references its presence in personal care products like shampoos.

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.
 
chemfinder don't got it
is not found ne where =(
