Meaning of "Nonyl-phenol 10 mole"
Nonylphenols are a family of closely related organic compounds composed of phenol bearing a 9 carbon-tail (Wikipedia). Following is an example of nonylphenols:

However, &quot;Nonylphenol $n$ mole&quot; is a commercial name for non-ionic surfactants where $n$ stand for the amount of ethelene oxides (EO) in moles in one surfactant molecule. For example, if the non-ionic surfactant is $\ce{R-O-(CH2CH2-O)n-H}$ where $\ce{R}$ is hydrophobic tail of the surfactant, the commercial name &quot;Nonylphenol 10 mole&quot; means $\ce{R-O = 4-C9H17-C6H4-O}$ and $n = 10$ in the structure. An example for a linear chain non-ionic surfactant is pentaethylene glycol monododecyl ether:

where $\ce{R-O = C12H25-O}$ and $n = 5$ (available in Sigma-Aldrich).
