    Chemical Engineering Hey! I have an idea for a teeth whitening paste in my mind for many years and now finally I have time to make it come to life. Since I am a mechanical engineer, I am not skilled to develop such tooth paste on my own so I am looking for a freelancer to help me with it. I have more than 1 tooth paste formula in mind. After successfully completing this project, I would be happy to hire you again and pay more. I need a chemist to develop and formulate an all natural teeth whitening toothpaste making sure it is unique (there is nothing similar on the market). I have the idea of which ingredients I want in the paste. After developing the formula, the product needs to be laboratory tested. Testings should include whitening experiments, stability test (shelf life), abrasiveness test, pH testings, flow testing, flavor testing. As an expert, please let me know which other tests you think should be done on the product. After the formula was created and tested, I would need a developed manufacturing process. Have you had experience in developing similar products? Please let me know which ones. What other testings come to your mind for this product? Please describe them. Do you have a proper laboratory to undertake all the testings? How long do you think the development process will take?

    Hello, I'm looking to consult with a chemist/engineer that has specific knowledge in the realm of color pigments. For example, Red 34, Yellow 5, Iron Blue, etc. We're using pre-dispersed pastes produced by 3rd parties but we're having trouble getting uniform color from batch to batch (of our product) even with accurate ratios of the same batch of pigment. I've read about color "development" and how the intensity of a pigment can potentially increase after some aggressive dispersing. For instance, page 4 of the PDF attached shows how pigments develop stronger color after being "Osterized" for a longer period of time. I'm hoping to find someone that can work with us to develop the necessary procedures to maximize / control color development in our application so that we can confidently create new product batches with a consistent color to them. If you can help with this, please leave a message and we can discuss what is required before agreeing to a flat or hourly rate for the project.
