Nonylphenol salts of Barium as well as calcium have application as heat stabilizers in plastic. Nonylphenol phosphate esters are used to retard flame. Nonylphenol is raw material for Nonlyphenol ethoxylate which is used in Surfactants.

Nonylphenol Ethoxylates have various molecular weights and properties. The properties of a particular Nonylphenol Ethoxylate depend upon the number of ethoxylate groups that are attached (the number of ether linkages along the chain), which can vary from just a few up to about one hundred.

NPE accounts for approximately 85% of alkylphenol eth-oxylate production (Anonymous 1997). 4-nonylphenol polyethoxylates (4NPnEOs) are 4-nonylphenol isomers that exist in both branched and linear forms and contain an ethoxylated phenol ring with varying grades (chain lengths) of n ethoxylation. Technical 4NPnEO products are sold with varying grades of ethoxylation including up to a grade of 70 .
