Surfactant for stripper?

[Andy Hinson 14]

What is a surfactant to use with caustic soda or oxalic acid?

[RPetry 564]

Andy,

Tergitol NP-9, otherwise known as Polyoxyethylene Nonylphenol. Since the Dow Chemical patent has expired, it is available from numerous sources. The Chemistry Store carries it, go to: NP-9 by The Chemistry Store.com Inc

2-butoxyethanol 2-Butoxyethanol - Wikipedia, the free encyclopedia may be what your after.. aka butyl cellosolve. Is a solvent found in most major cleaners, degreasers, floor stripper etc.. Since it breaks down fairly quik in environment some market the products containing it as biodegradable. For use in wood restoration/stripping mixes some forego buying it in bulk form and just buy Purple Power or a floor stripper. Pour some in that finicky fiver of undisolved heat and watch it disolve in about a blink of an eye. Far as surfacting or wetting goes such werks fine.. :)

If your looking to get an acid to wet better I know that 2 butoxy is used with many acids such as phosphoric, citric, and glycolic as metal cleaners or rust removers. Use this Dow formula tool to see how the various chems can be utilized:

Here is Dow's info on 2-butoxy

Remeber there is more concern for enviroment with the NP stuff:

http://en.wikipedia.org/wiki/Nonylphenol

"Nonylphenol has been detected widely in waste water streams across the globe, which is a concern since it is toxic to many aquatic organisms. For example, nonylphenol has been detected both in the Great Lakes and in the region of New York City.[6] In 1984, the formation of 4-nonylphenols from nonylphenol ethoxylates in wastewater treatment plants was first discovered.[7] Nonylphenol is persistent in the environment,[8] therefore lingers around to potentially negatively effect organisms it comes in contact with. Nonylphenol also bioaccumulates, which is dangerous to animals and humans who eat meat.

Nonylphenol and nonyphenol ethoxylates have been banned in the European Union as a hazard to human and environmental safety.[9]

For freshwater ecosystems, the Environmental Protection Agency has set two types of standards: the first which is considered acute criteria is one-hour average concentration of nonylphenol does not exceed 28 μg/L more than once every three years on the average.[10]

For saltwater ecosystems, the standard is considered to be chronic criteria and is set to four-day average concentration of nonylphenol that does not exceed 6.6 μg/l more than once every three years on the average."

If wanting to stick with tergitol surfactant for sake of pure surfactance properties try this: http://www.dow.com/surfactants/products/second.htm

Is safer more common version of their Tergitol.

Again you can try the formula tool linked above to get ideas or their surfactant tool below. Note that the Tergitol15 is usually mentioned.
