Multiple Skin Formulations pH Testing by FDA GLP Laboratory

Project Description

Canada or USA FDA GLP Laboratory needed for pH Testing of multiple skincare formulations. For the Laboratory Report, the following is required:

- pH meter (manufacturer & model) & electrode used (manufacturer & model)
- Is the electrode suitable for the product matrix being tested ?
- methodology for the calibration of the equipment and measurement of the pH of the product
- calibration buffers used (calibration range should encompass the actual pH of the product)
- final pH of the product (as applied onto the skin - undiluted) ? to two decimal places
- Directions for use/application details for each product, as found on product labelling
