Zeiss is arguably a leader in optics, but I am surprised by how abrasive their wet wipe paper is. It is definitely not a soft cloth, nor does it have fibers to trap small particles. Thus, anything caught in between the cloth and the object you are wiping may scratch the object.
For your phone back, it should be fine. For fine and delicate lenses, I am not so sure. Although I have never noticed any scratches by using them, it doesn't make me feel comfortable about it.
Also, if you look at the ingredients, you'll see it is just a mix of ethyl alcohol (rubbing alcohol) and probably deionized water. You should be fine. I personally just use a douse of 70% ethyl alcohol on my MBP (keys, trackpad, case, and even the screen if there are spots on it) and it has been fine for 3 years. However, I use it with a microfiber cloth.
