I often see Skidmore's Leather Cream mentioned as THE stuff to use on leather so got curious about it. They advertise it as all-natural ingredients, but when I went looking for the MSDS it came up with this - beeswax and Heavy paraffinic distillate 64742-54-7, which is obviously the solvent. This is made from oil and is used in many motor oils so calling it natural is, to my way of thinking, stretching things just a bit.
Many leatherworkers are fussy about not using petroleum-based products on their leather but I wonder how many realise what is in Skidmore's.
Food for thought.
