Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.
In the US, the alternative name for parfum is 'fragrance'.
The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.

One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.

Parfum can also be used to mask or cover an unpleasant scent.
