I need a color-changing paper test (similar to a litmus test) for testing sugar-alcohol. Something small in size, like a small strip of paper. When breath containing 0.17g any of these sugar alcohols (Xylitol, Mannitol, Sorbitol, Glycerol, Erythritol) is blown on strip of paper, it should change color.

Hello: Seeking a chemist in the Chicago area to formulate a new nail polish. Does anyone have experience with this? I am new and am seeking to learn and understand everything involved with this process. Currently there are suspension base formulas that you can buy on the market to mix with your own pigments and glitters to form different colors but I am interested in forming my own base formula. Typical formulas involve solvents, resins, thickeners, plasticizers. If you are interested please send me your bid! Thanks.

I am looking to purchase a specific ink from an ink manufacturer in China. I'm looking for Hydrochromic Textile ink. Ideally I would like for it to cost $80 [USD] for a 4 kg supply. That would include all costs (shipping...etc...). I'm looking for a company that would allow me to order a minimum of 4 kg. If you can't find a company that would satisfy these terms, I will entertain close offers. I would like the name of the company, email, website and other relevant contact information. Thank-you.

We are looking for a chemist that has significant experience in formulating cosmetics such as creams, serums, lotions and gels. However, what we need the most right now is someone with experience formulating teeth whitening gels. We make hydrogen peroxide and carbamide peroxide teeth whitening gels as non-peroxide teeth whitening gels. If you have experience formulating and manufacturing teeth whitening products, we definitely want to talk to you. We are also formulating some lotions and serums for anti-aging, anti-acne and a few other purposes, but that will come after we have resolved some of the technical issues we have with the peroxide gels. We have sophisticated production equipment and all the lab equipment we could possibly need. We need someone that has experience formulating these kinds of products AND experience in manufacturing them.

Is it possible for an indicator to show an electrode pH change in dilute NaOH or in a mix of NaOH and citric acid? (yes or no, then talk me through your logic) I have done significant research into this, but it is above my chemistry understanding. I do not want a review of the internet; as I have already exhausted this source. I need someone with high level chemistry thinking to answer this question with minimal research. I am in need of a chemist to ask similar questions for my engineering design work in the future. If it is a positive experience I will definitely be a reoccurring client.
