Dir Sirs,
Surface chemistry is my specialisation, I took my PhD in the area of surface chemistry from the best swedish university of technology. I worked on many similar projects related to surfactans, for example I designed washing liquids for biochemistry analyzers for big biotech company, designed windshield washer liquids, designed several different washing solutions.
I'm very familiar with different formulations related to cleaners, washing liquieds, dish washing liquids etc. I'm also a chemical technologist and can help you with manufacturing process. I can provide you my diplomas if necessary.
I'm confident that I'm able to provide a professional expertise and help in terms of formulation and manufacturing process for a very high quality car wash liquid.
Should you have any questions, I will be happy to help you.
