Discussing the safety of a fragrance requires distinguishing between several concepts that are often confused: hazard, risk, dose, and exposure. A material may have an intrinsic property requiring risk management without this meaning that a finished product used as intended presents the same level of risk.
Hazard and risk: two different concepts
Hazard describes an intrinsic property of a substance or mixture: for example, its potential ability to cause an adverse effect under certain conditions.
Risk then depends on how that substance is used and on the actual exposure. In perfumery, the quantity, type of product, frequency of use, and route of exposure are therefore important.
Why dose matters
The same substance does not necessarily lead to the same level of risk depending on the quantity to which a person is exposed. Safety approaches in perfumery therefore incorporate hazard data and exposure scenarios.
IFRA describes its Standards as a risk management system that may prohibit, restrict, or regulate certain ingredients according to the available scientific data. The limits are expressed for the finished product and depend in particular on the category of use. See IFRA’s explanations of its Standards.
Exposure: fragrance on skin, soap, or home fragrance
A fragrance applied to the skin is not used in the same way as a product that is quickly rinsed off or a product intended to scent the air. The exposure scenarios differ.
| Concept | Question |
|---|---|
| Hazard | What potentially harmful property does the substance have? |
| Dose | What quantity is involved? |
| Exposure | How, for how long, and how frequently is the person exposed to it? |
| Risk | What does the assessment of these factors show in a given scenario? |
Allergen does not automatically mean “dangerous fragrance”
The presence of a substance identified as an allergen deserves careful consideration. European regulations require consumers to be informed about certain fragrance allergens, while safety assessments take exposure and use levels into account.
IFRA explains that its approach to skin sensitization is based in particular on a quantitative risk assessment, comparing estimated exposure with a level considered acceptable in the scenario under study. IFRA documentation on risk assessment.
What about natural ingredients?
Natural does not automatically mean safer. A natural material is also made up of chemical substances, sometimes many of them, and some may require restrictions or exposure management. Conversely, “synthetic” alone is not an indication of hazardousness.
The relevant question is therefore: which substance, at what concentration, in which product, and with what exposure?
Why essential oils deserve particular consideration
An essential oil is a complex natural material. Its profile depends in particular on the plant, the part used, and the extraction process. Some of its constituents may be considered individually in the applicable assessments and restrictions.
This explains why “natural,” “essential oil,” and “risk-free” are not synonyms.
IFRA and European regulations: do not confuse them
IFRA Standards constitute a voluntary industry risk management system, mandatory for IFRA members under its Code of Practice. They do not replace the applicable national or European regulations.
IFRA also specifies that it does not itself certify products or their individual compliance. Final responsibility for a product placed on the market remains with the company concerned. Understand what IFRA compliance really means.
A simple method for assessing a safety claim
- Identify the substance or material being discussed.
- Identify the hazard being cited: irritation, sensitization, another toxicological effect, etc.
- Consider the exposure: product, area, quantity, duration, and frequency.
- Distinguish a regulatory obligation from a voluntary recommendation.
- Do not draw conclusions from the word “natural” or “synthetic” alone.
Key points
Hazard ≠ risk. Natural ≠ risk-free. Allergen ≠ automatically dangerous product. A serious assessment of fragrance safety must place the material in its context of use and consider dose and exposure.
