The INCI list (International Nomenclature of Cosmetic Ingredients) is mandatory on every cosmetic product sold in Europe. It enumerates all ingredients in descending order of concentration. It is the sole standardized and regulated source of information about what a product really contains—far more reliable than any marketing claim presented on the front of the packaging.
The problem is that it is written in Latin and English, with names that look more like chemical formulas than a straightforward ingredient list. As a result, most consumers ignore it. And that’s precisely where brands can exploit ambiguity.
What the INCI List Really Reveals About an Organic Skincare Product
The fundamental rule to remember: the order in which ingredients appear is information in itself. The ingredients present in the highest amounts appear first. Those listed at the very end of the list (after the 1% concentration threshold) can be listed in any order, and their actual impact on the formulation is often marginal.
Concretely, that means a product that loudly touts “rose oil” on its packaging, but where that oil only appears at the 28th position in the INCI list, probably contains only an anecdotal amount of that ingredient. It isn’t prohibited. But it isn’t what the consumer imagines.
Ingredients to Look for at the Top of the List
In a serious organic skincare product, the first positions are typically occupied by:
- Aqua (water): the base of most formulations
- Vegetable oils (e.g., Helianthus Annuus Seed Oil for sunflower, Simmondsia Chinensis Seed Oil for jojoba)
- Plant extracts or floral waters (Rosa Damascena Flower Water, Aloe Barbadensis Leaf Juice)
- Certified organic actives, identifiable by an asterisk (*) at the foot of the list
For example, a well-formulated organic facial serum will display its primary actives (biotechnologically derived hyaluronic acid, concentrated plant extracts) in the first third of its INCI list. If the flagship ingredient only appears near the bottom, the product’s promise should be questioned.
The Ingredients That Should Trigger Alarms
Even on products marketed as “natural,” certain compounds are incompatible with a serious organic certification:
- PEGs (polyethylene glycols) and their derivatives: synthetic emulsifiers
- Parabens (Methylparaben, Propylparaben): controversial preservatives
- Silicones (Dimethicone, Cyclopentasiloxane): synthetic texture agents
- Synthetic fragrances (Parfum or Fragrance): potential allergens with no details
- Phenoxyethanol: synthetic preservative, tolerated in small amounts but absent from Cosmos Organic formulations
Organic Certification and the INCI Label: How to Connect the Dots
Seeing the word “bio” on a package isn’t enough. You need to know what certification lies behind it and what it actually guarantees.
The two most reliable benchmarks on the European market are Cosmos Organic (administered by Ecocert, among other bodies) and Nature & Progrès. Their requirements are specific: 95% of ingredients must be of natural origin, a minimum percentage of ingredients must come from organic farming (for example, 20% for non-rinsed products like facial care), and they provide a list of disallowed ingredients. A certified Cosmos Organic product cannot rely on a trivial sprinkling of organic actives—the certification applies to the entire formulation.
For example, a face cream labeled Cosmos Organic has undergone independent verification of its composition, something no marketing claim, however persuasive, can guarantee.
In practice, when you read a label on a certified product, you’ll often see little asterisks next to certain ingredients, with a note such as “ingredient sourced from organic farming.” This marking indicates that the ingredient in question is organic: a concrete transparency element that serious brands highlight, making it easy for consumers to identify certified ingredients amid the entire formulation.
4 Concrete Habits to Read an INCI Label Without Getting It Wrong
You don’t need to become a chemist. A few simple habits are enough to distinguish a genuinely organic product from one that merely uses the lingo without meeting the standards.
To Go Further
Reading an INCI label means reclaiming control over what you apply to your skin. It isn’t reserved for experts: it’s a skill you can learn quickly, and it will permanently change how you shop for skincare.
