To Be or Not To Be—‘Natural’. What’s in a Name?
A naturally-occurring chemical is one of the following: Either, an unprocessed chemical occurring in a natural environment — chemicals obtained from plants, microorganisms, the earth, sea or animals without any processing at all, for example blood and milk from animals, minerals, ores, crude oil, coal and natural gas obtained without any processing; OR, a chemical occurring in a natural environment that is extracted using a process that does not cause a chemical change in the substance — this refers to chemicals that occur in nature but which have been extracted using certain processes without changing their chemical composition. If introducers and suppliers extract a chemical by some other means, such as steam distillation or solvent extraction, it will not be a naturally-occurring chemical.
