PureScent Suspected Ingredient List

Which fragrance ingredients are classified as suspected carcinogens, mutagens or reproductive toxins (CMRs), and how we flag them on our oils.

Some fragrance ingredients are classified as suspected carcinogens, mutagens, or reproductive toxins (CMRs): early research has raised a possible concern that still needs further study. A suspected ingredient is different from a known CMR, which no PureScent oil contains at all.

PureScent oils may contain a suspected ingredient. When one does, we name it on that oil's product page in a line that reads “This fragrance contains…” so you can decide for yourself. PureScent+ oils contain none of the ingredients below.

How an ingredient makes this list

An ingredient is listed if any of these classify it as a suspected CMR (GHS Category 2: H341, H351, or H361):

  • Supplier SDS: the ingredient classification our fragrance supplier prints in Section 3 of its safety data sheets.
  • EU notifiers (ECHA): the classification most companies notify to the European Chemicals Agency.
  • Industry clean-fragrance list: ingredients named as suspected by other clean-fragrance programs, based on the fragrance industry's RIFM safety reviews.

Some suspected ingredients occur naturally in essential oils. gamma-Terpinene and p-cymene, for example, are natural parts of citrus and herb oils, and we name them whether they were added or came from a natural oil.

The list

May appear in PureScent (15)

When a PureScent oil contains one of these, we name it on that oil's product page.
