Zeiss has multiple divisions offering lens cleaning stuff, and they do not always have ingredients that the other division endorses.  This issue first came to light in 2009.
The MSDS for 
Zeiss Lens Cleaner containg nothing but
- isopropyl alcohol and
- water
The MSDS for 
Zeiss Lens Cleaning Sheets contain
- AQUA Water
- Propan-2-ol Propanol
- Ethanol Ethanol
- 5-CHLORO-2-METHYL-2H-ISOTHIAZOL-3-ON
- Methylchoroisothiazolinon 2-METHYL-2H-ISOTHIAZOL-3-ON  Methylthiazolinon
The MSDS for 
Zeiss Lens Wipes contain
- Glataral
- Magnesium Nitrate
- 3-iodo-2-propynyl butylcarbamate
- reaction mass of: 5-chloro-2- methyl-4-isothiazolin-3-one [EC no. 247-500-7]and 2-methyl-2H -isothiazol-3- one [EC no. 220-239-6] (3:1)
The MSDS for 
Zeiss Lens Cleaner Towelettes contain
- Isopropyl alcohol
This is the list of ingredients on the Zeiss website for its current (Jan 2023) lens cleaning solution MSDS, and Lens Cleaning Spray MSDS
- AQUA
- BUTOXYDIGLYCOL
- DIMETHYLOL GLYCOL
- GLUTARAL
- METHYLCHLOROISOTHIAZOLINONE
- METHYLISOTHIAZOLINONE
WHICH ONE is anyone buying?!  I would only use the first product and the fourth product listed above, as they meet Zeiss Photographic and Zeiss Microscope divisions' recommendation:
Here is what the Ziess microscope division currently (Jan 2023) says
"First use distilled water or breath on the front lens and clean with a cotton swab to remove water-soluble dirt.
...Repeat using a solvent such as 70% ethanol to remove oily or greasy dirt"
Does anyone see mention of any other chemical apart from plain ethyl alcohol and water?!
