Ed. note: This thread received two generous answers early-on. But since then, we've posted 20 questions in a row. C'mon now, folks, you probably know enough to give a hint on one of those unanswered questions. Thanks!
Q. Dear sir,
I am a master research student in chemistry. Currently I'm working on a project of nano-emulsion water emulsified diesel-biodiesel (palm methyl ester) in diesel engine application. The characteristics of desired novel surfactant is from plant base such as palm oil, which means it does no harm to the environment but yet it is able to form water in oil emulsion and in nano size and also easy to combust. In order to get those characteristics I have tried fatty alcohol ethoxylate. Raw material that rich in oxygen group can enhance the combustion efficiency process; besides biodiesel contains a water addition in the system. This emulsification method based on low energy by using titration method. However in most of my findings in reading materials, they are using blending emulsification methods such as high homogenizer pressure which means use of high energy. For this moment, I'm still in screening process to figure out the best non-ionic surfactant that is able to form water in oil emulsion in nano size. Would you kindly give me some suggestion and a list of non-ionic surfactants that can help me to figure out the solution? I thank you in advance for your attention and co-operation.

Q. Hi Drs., Hope you will be happy and good. I want to know that I am doing work with ZnO and getting different morphologies for gas sensing using hydrothermal method. I want to know which surfactant can be good that I can use getting better results? And suggest some methods to prepare it also, thanks. I'm doing Ph.D in material Science in China.

Q. Sir, we have read so many research papers for determination of surfactant through dye in visible range. But, is it possible to determine presence of surfactant (SdS and CTAB) through U-V range? because we wish to work on this method.

A. As I have gone through above question, you all are mostly looking for Nonionic Surfactant; I will suggest as per my work on same research (NONYLPHENOXYPOLYETHOXYETHANOL) NONIONIC SURFACTANT
This is the best one to use for the same and it is biodegradable.

Q. I am working on using a kind of nonionic surfactants as antifoam.
Therefore I would like to get your help to have a list of nonionic surfactant as defoamer.
Thanks.

A. It is my understanding that some low HLB non-ionic surfactants behave as antifoams because they are partially insoluble - in other words the solution/suspension is above the cloud point of the surfactant. This is a dangerous road to travel in metal finishing. Been there, done that.

A. I know enough about surfactants to know that any and all of them would be good enough for a lot of general cleaning conditions.
I don't know enough about surfactants to say how the cleaning properties are affected by the large number of variations that can be found in the physical structure of surfactant molecules across the industry. I suspect that is largely true for everyone who isn't a chemical engineer at a surfactant manufacturer.
I would suggest to folks here with questions on surfactants to actually go directly to the surfactant manufacturers. The product literature on their websites usually gives at least a vague sense of how their different products are expected to behave, and you can always contact them directly, describe your problem, and ask which product they recommend.

But every once in a while we get a thread where dozens of posters aren't helping each other. Then we remind folks that this is not some sort of free consulting service, but a place of camaraderie, aloha, & mutual assistance. And if the list of unanswered questions grows relentlessly anyway, it can become time to close the thread and stop being silly :-) Regards,  Ted Mooney, P.E. RET Striving to live Aloha finishing.com - Pine Beach, New Jersey January 2016 January 16, 2016 Good day Ted.
Regards, Ted Mooney, P.E. RET Striving to live Aloha finishing.com - Pine Beach, New Jersey January 2016 ! Wow, just wow. I stumbled across this while looking for some info on a cosmetic emulsifier and (though not really relevant to my search) kept reading with a kind of fascinated horror at the number of people who ask for the world, with no word of thanks or acknowledgement of how much they are asking. You guys/mods here are polite, I would have sent some of these folks packing and closed the thread. - Los Angeles, California April 4, 2016

PI - Bhagalpur INDIA February 20, 2017 Hi cousin Ravi. This site has 50,000 topics, and I've tried to help on thousands of them. But I know absolutely nothing of surfactants; so all I can do as site administrator is urge people to try to answer. I appreciate when people look kindly on the site; and when they don't like it, I try to improve things -- so thanks for the suggestion. But ad hominem comments aren't a good reason for readers to spend their limited time here ... so please offer a question or answer. Thanks again. Regards, Ted Mooney, P.E.

OK I ACCEPT THAT THOSE WHO KNOW THE ANSWERS OF THE QUESTIONS ASKED IN THIS THREAD MUST GIVE REPLY TO THOSE QUESTIONS. BUT IT IS BAD MR. TED THAT YOU BEHAVE LIKE THE BOSS OR ADMINISTRATOR OF THE THREAD AND TEACH OTHERS WITH YOUR IDIOTIC COMMENTS. HAVE YOU EVER TRY TO GIVE ANY REPLY OF ANY QUESTION ASKED IN THIS FORUM OR YOU ARE HERE TO CRITICIZE OTHERS?A? : hopefully...
Okay, although both questions are long past, others still might be seeking answers. I can only say the following information is from my actual experience & may NOT be something one would find in a chemistry or engineering text and possibly not relevant to metal finishing?, But still, to my best knowledge, true:
RE:the Q. of Swapan Ghosh, posted: 06/10/13, RE: the suitable emulsifier to get homogeneity & stability for combining a hydrated silica solution & essential oil(s);
If he had succeeded in incorporating the silica (dissolution as vs. dispersion), I'd recommend polysorbate 20 for the volatiles..however, instead of using a 1:1 ratio of the solubilizer & the ess. oils, I'd begin there, but be willing to increase by a factor of @ least 3x as much poly20 as ess. oils..the objective being an attempt @ a clear solution(if this is even possible w/the silica present-although it should be a simple matter depending on the initial method used to solvate the hydrated silica).
RE:the Q. of Fatima Tariq, posted: 11/22/15, RE: which surfactants are suitable for use w/ polymers for functionalization; if working w/the polymer, carbomer, one can sometimes successfully neutralize & open up the coils, in order to create an elegant rheological structure, using the high pH surfactant, Decyl Glucoside, in place of the conventional sodium hydroxide, or TEA (although, I'm unsure how long a formula like this will retain its shape & thickness; one would have to experiment).
That's all I have. I hope its of some assistance, even if just for joke-fodder...
best regards to you all, truly an enlightening thread & forum, thank you for your time and attention, much love, suki

A. Hi Neethu,
You can look for Dr. Saha's answer up in this very page, he lists very thoroughly a very large number of substances used as non-ionic surfactants.
They are esters, alcohols, amides and polyethers of fatty acids, and have a very long alyphatic "tail" and a polar "head" in its molecular structure. One part of the structure is hydrophilic and the other part is hydrophobic. This basic construction is the base for surface active substances, or "surfactants" :)
Best regards,
