I would think twice about using this product. It contains a naptha solvent for cleaning and will compromise your leather over time. The solvent will attack the protective coating on the leather. Over time, the coating will come off with repeated use which causes loss of color and flexibility. Solvents are not good for leather. My father first introduced me to Collinite L&V T.
Collinite is a small, unique company that is old school and noted for their high quality waxes that are discussed on detailing forums. They do not come out with new products and do not change existing stuff. They are updating some products only due to VOC regs that many are aware of. It leads me to believe IMHO that they have a couple of All-Stars in their line-up that they are riding; unlike others who are constantly refining and upgrading. Don't get me wrong. I have used their wax for five years. My guess is that the leather formula has been around for quite some time.
It's like poker. Keep your best and throw out the rest. Keep the wax and get dealt some new choices for your leather. Also, why not go with both a cleaner and a protectant for the leather? One step products often compromise protection to meet the cleaning need. Good Luck!
