What INCI is in perfumery and why it appears on the label.

When a customer looks at a perfume label and finds names such as Alcohol Denat., Parfum, Aqua, Limonene, Linalool or Coumarin, it is normal for them to ask what that list means and why it is not written as a simpler commercial description. That information belongs to the INCI system, an international nomenclature for cosmetic ingredients that allows the substances used to be identified consistently across the market.

For a shop, distributor or private label, understanding INCI is not a minor technical detail: it helps explain the product better, avoids confusion with the consumer and allows the communication of a perfume line to be organised more professionally.

What does INCI mean and why is it used in cosmetics?

INCI stands for International Nomenclature Cosmetic Ingredient. It is an international nomenclature used to name cosmetic ingredients in a common way. Its function is to ensure that the ingredient list does not depend on the commercial language of each country or on marketing interpretations, but on names recognised within the cosmetics sector.

This is especially useful in the European Union, where the same product may be sold in markets with different languages and still needs to maintain technical information that can be understood by authorities, professionals and consumers.

To check specific names and ingredients, it is also possible to use the official European Union CosIng search tool, a useful reference for INCI names and cosmetic substances.

In practice, INCI helps separate the commercial description of the product from its regulatory identification. A shop may present a fragrance as fresh, floral, woody or intense, but the label must reflect the composition through the required nomenclature. That list is not intended to tell an olfactory story, but to inform about the ingredients present.

For the end customer it may seem like complex language, but for the sector it is a tool for transparency, traceability and consistency across markets.

Why does a perfume show “Parfum” instead of all the fragrance components?

In perfumery, perfume and aromatic compositions are normally identified in the ingredient list with the term “Parfum” or “Aroma”. This does not mean that there is no formula behind the product, but that the fragrance composition is declared under that term within the cosmetic labelling system.

The detailed formula may be part of the technical documentation and safety assessment, but it is not fully displayed on the commercial label for technical, regulatory and industrial confidentiality reasons.

However, there is a very important exception: certain fragrance substances must be declared individually when they exceed established thresholds. This is where fragrance allergens come in. That is why a perfume may show “Parfum” and also specific names such as Limonene, Linalool, Citral, Geraniol or Coumarin.

These ingredients do not appear because the shop wants to make the label more complicated, but because regulation aims to help sensitised people identify substances they need to avoid.

What should a shop know when a customer asks about the ingredient list?

The best answer is not to turn the sale into a technical class, but to explain that the INCI list identifies the product’s ingredients using a common cosmetics nomenclature. A professional shop can build trust if it can explain that the list informs the consumer, makes relevant substances easier to identify and complies with labelling requirements.

In a market where sensitivity to ingredients is increasing, answering clearly can become a commercial advantage.

It is also advisable to avoid absolute or risky answers. Saying that a perfume “does not cause allergies”, “contains no allergens” or is “completely harmless” can be problematic if there is no technical basis to support it.

A more prudent answer would be to explain that the product is formulated and labelled according to the applicable framework, that the ingredient list allows declared substances to be reviewed and that people with known allergies should always check the components indicated on the label. This way of communicating is more professional and reduces the risk of improper promises.

How are ingredients ordered on a perfume label?

The ingredient list is ordered in descending order according to weight at the time the ingredients are incorporated into the product. This means that ingredients with a greater presence usually appear first. Ingredients with a concentration below 1% may be mentioned after those above that level without having to follow a strict descending order.

In perfumes, it is common to see base ingredients such as alcohol, water where applicable, the perfume composition and then declarable substances according to their concentration and function.

This criterion helps prevent the label from becoming an arbitrary list. For a private label or refilling project, the correct order of ingredients should not be improvised from a generic template. It must come from the product’s technical information, the final formula, the supplier’s documentation and the corresponding regulatory review.

A visually attractive label loses value if the ingredient list is not properly structured.

Can INCI help sell better or is it only for compliance?

INCI is not an emotional sales argument, but it does help build trust. In the B2B market, a shop that works with properly documented products can convey more confidence than one that only talks about equivalences, longevity or price.

The ingredient list shows that the perfume has been prepared with a professional logic and that essential information is not hidden. In international operations, the existence of a common nomenclature also makes it easier to adapt labels and content without changing the technical basis of the product.

It can also help train the sales team. Sellers do not need to memorise every ingredient, but they should understand basic concepts: what “Parfum” means, why allergens appear, what an international nomenclature is and why it is not advisable to promise absence of risk.

In professional perfumery, sales are not based only on the scent; they also rely on the trust generated by a product that is well presented, well documented and well explained.

How can a specialised supplier help prepare labels with INCI?

At VismarEssence, we work with a professional view of perfumery, where fragrance selection, supply, technical documentation and commercial presentation are part of the same project. For a shop, distributor or private label, relying on a specialised supplier helps reduce uncertainty, organise the catalogue better and prepare a stronger proposal before going to market.

That is precisely why the regulatory side should be treated as a phase of business development, not as a last-minute correction when the product has already been designed, labelled or sold.
