In summary, the conversation is about a chemical compound that is likely a detergent. It has a structure similar to benzene sulfonate with a dodecyl group substituted, and can form a sodium sulfonate salt. It acts as a surfactant, allowing oil and water to mix. The specific compound being discussed is tetraethylammonium-dodecylbenzenesulfonate, which is found in some shampoos. It can be searched using its CAS number 25155-30-0 on chemfinder.com and has a molecular weight of 348.47507. Its melting point is above 300 degrees Celsius and it has a solubility of 0.5-1.0

can some tell me what exactly it is?

like pesticide or something?

a littleabout the properties would be nice


thanks :D

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.

Related to Sodium dodecylbenzene sulfonate

1. What is Sodium dodecylbenzene sulfonate?

Sodium dodecylbenzene sulfonate, also known as SDBS or sodium linear alkylbenzene sulfonate (LAS), is a synthetic anionic surfactant with the molecular formula C18H29NaO3S. It is commonly used in household and industrial cleaning products as a foaming and emulsifying agent.

2. What are the uses of Sodium dodecylbenzene sulfonate?

Sodium dodecylbenzene sulfonate is primarily used as an ingredient in detergents, dish soaps, and laundry detergents. It is also used in various industrial applications such as in textile processing, oil recovery, and as a wetting agent in agriculture.

3. Is Sodium dodecylbenzene sulfonate safe to use?

Sodium dodecylbenzene sulfonate is generally considered safe for use in household and industrial products. However, it may cause skin and eye irritation in high concentrations. It is important to always follow the recommended usage instructions and wear protective gear when handling concentrated solutions.

4. How does Sodium dodecylbenzene sulfonate work?

Sodium dodecylbenzene sulfonate works by lowering the surface tension of water, making it easier for water to spread and penetrate surfaces. It also acts as a foaming and emulsifying agent, helping to lift dirt and oil from surfaces and keep them suspended in the water.

5. Can Sodium dodecylbenzene sulfonate harm the environment?

Sodium dodecylbenzene sulfonate is biodegradable and breaks down into harmless byproducts in the environment. However, it can be toxic to aquatic organisms in high concentrations. It is important to properly dispose of products containing SDBS and avoid releasing them into waterways.
