• The MSDS we shared contain all the information needed for MSDS.• One grease MSDS have detail because it has composition that need to be declared.• The other two grease MSDS, It is mentioned as non-hazardous, with no composition to declare. So, there is nothing mention there.• These 3 greases are different types with different composition. That is why they need different MSDS.• The intention of MSDS is not to list down all the composition, but to make sure the goods is not hazardous. They will only list down the composition that is required to be declared.• I can find many MSDS with the same statement for section 3. I captured some as below.
