IFRA Critical Effect:
Carcinogenicity
IFRA fragrance material specification:
 Safrole as such should not be used as a fragrance ingredient; essential oils containing safrole should not be used at a level such that the total concentration of safrole exceeds 0.01% in consumer products. Examples of essential oils with a high safrole content are Sassafras oil (Sassafras officinale Nees& Eberm.), Ocotea Cymbarum oil (Ocotea pretiosa Metz) and certain qualities of Camphor oils. The total concentration of safrole, isosafrole and dihydrosafrole should not exceed 0.01% in consumer products. These recommendations are based on the conclusions of the Scientific Committee on Cosmetology of the EEC on safrole and on the similarity of the biological activity of these substances (Scientific Committee of Cosmetology of the EEC, opinion reached on September 2, 1980; Communication to the EEC Commission ENV/521/79 and IARC Monograph Vol. 10, 1976, 231-244).

 Notes:
IFRA FLAVOR REQUIREMENTS:

Due to the possible ingestion of small amounts of fragrance ingredients from their use in products in Categories 1 and 6, materials must not only comply with IFRA Standards but must also be recognized as safe as a flavoring ingredient as defined by the IOFI Code of Practice (www.iofi.org). For more details see chapter 1 of the Guidance for the use of IFRA Standards.

Fragrance ingredient restriction - Note box
On the basis of established maximum concentration levels of this substance in commercially available natural sources (like essential oils, extracts and absolutes), exposure to this substance from the use of these oils and extracts is regarded acceptable as long as the total concentration of Safrole, Isosafrole and Dihydrosafrole in the finished consumer product does not exceed 0.01%.
 
Recommendation for safrole flavor usage levels up to:
 not for flavor use.

Notes:
constituent of several essential oils, notably sassafras. it has been used as a topical antiseptic and it is carcinogenic to the liver so it is no longer used as a flavoring agent in foods. Occurs in nutmeg. Banned by FDA for use in food. Formerly used as a food flavour It is a precursor in the synthesis of the insecticide synergist piperonyl butoxide and the recreational drug MDMA ("Ecstacy."); Safrole is a natural plant constituent, found in oil of sassafras and certain other essential oils. It is a member of the methylenedioxybenzene group of compounds, many of which (e.g. piperonyl butoxide) are extensively used as insecticide synergists. A major source of human exposure to safrole is through consumption of spices, such as nutmeg, cinnamon and black pepper, in which safrole is a constituent. Safrole is also present in root beer, and has been used as an additive in chewing gum, toothpaste, soaps and certain pharmaceutical preparations. Safrole is a weak hepatocarcinogen and it is a matter of considerable interest whether the ally1 moiety or the methylenedioxy group, or both, are involved in the mechanism of its carcinogenesis. Safrole is extensively metabolized, giving rise to a large number of metabolites. Metabolism involves essentially two major routes, oxidation of the ally1 side chain, and oxidation of the methylenedioxy group with subsequent cleavage to form the catechol. Safrole undergoes oxidation of the allylic group to yield the 2, 3-epoxide (safrole epoxide). The dihydrodiol is one of the metabolites of safrole, and presumably arises from the hydration of the 2, 3-epoxide. The principal route of metabolism of safrole is through cleavage of the methylenedioxy group, the major metabolites being allylcatechol and its isomer, propenylcatechol. Eugenol and its isomer I-methoxy- 2-hydroxy-4-allylbenzene have been detected as minor metabolites in the rat, mouse and man. (PMID: 6719936); Safrole, also known as shikimol, is a colorless or slightly yellow oily liquid. It is typically extracted from the root-bark or the fruit of sassafras plants in the form of sassafras oil, or synthesized from other related methylenedioxy compounds. It is the principal component of brown camphor oil, and is found in small amounts in a wide variety of plants, where it functions as a natural pesticide. The Ocotea cymbarum[verification needed] oil made of the Ocotea pretiosa[verification needed], a plant growing in Brazil, and sassafras oil made of Sassafras albidum, a tree growing in eastern North America, are the main natural sources for safrole. It has a characteristic "candy-shop" aroma.
