Fragrance Fact: Perfume vs Fragrance

The words "perfume" and "fragrance" are often used interchangeably. However, these words have different meanings. Fragrance is the term for all substance regardless of its concentration - Parfum extract, Eau de parfum, Eau de toilette or Eau de cologne, while perfume should only be used for those with highest concentration. While it is acceptable for a typical person to talk about fragrances using the term perfume, one should be aware of the difference and be careful when using the term technically.
