What are higher alkyl sulphates and how are they used in cleaning products?

[danago]

Hey.
I was looking at the chemicals in a certain cleaning product, and there was one that i am unfamiliar with (and couldn't really find relevant information about). The product has been claimed to contain "Higher alkyl sulphates". What does this refer to? What are alkyl sulphates, and what does the "higher" refer to?

Thanks in advance.
Dan.

PS. I am a first year engineering student and have yet to take any chemistry units, so my chemistry knowledge doesn't go past high school chem.

It is probably in reference to the carbon number.

Higher alkyl sulphates refer to a class of chemical compounds that are commonly used in cleaning products. They are surfactants, which means they have properties that allow them to decrease the surface tension of water and help it spread more easily. This makes them effective in removing dirt, grease, and other substances from surfaces.

The "higher" in higher alkyl sulphates refers to the length of the alkyl chain in the molecule. Alkyl chains are hydrocarbon chains (made up of carbon and hydrogen atoms) that can vary in length. In this case, "higher" means that the alkyl chain is longer, typically consisting of 12 or more carbon atoms.

Alkyl sulphates are typically produced from petroleum or coconut oil and are then chemically modified to create the desired properties for cleaning products. They are commonly found in laundry detergents, dish soaps, and other household cleaners.

It is important to note that while alkyl sulphates are effective in cleaning, they can also be harsh on the skin and the environment. Therefore, it is important to use cleaning products containing these compounds as directed and to dispose of them properly. As a first year engineering student, you will learn more about the properties and uses of these compounds in your chemistry courses.
