Dear Sirs,
I'm a PhD in Chemistry, my specialization is surface and organic chemistry. I have huge general experience in chemistry (20 years +) and very broad knowledge in this area. Last 4 years I worked at the University of Warsaw as a PostDoc.
I have a big experience in surface active agents which are common ingredients of shampoos, cosmetics etc. I worked on several projects related to such mixtures.
I would like to help you with the task that you need. Please contact me via messanger at freelancer.com to discuss your requirements and expectations.
best regards
