Most people choose skincare products by scent, texture, or packaging. As a brand founder, you cannot afford to. The ingredient list ? called an INCI list ? is a standardised, legally required declaration of every substance in a product. It is the same system used in Malaysia, the EU, the US, and most markets worldwide. Learning to read it takes about ten minutes. What you gain is the ability to evaluate any formulation, anywhere, with confidence.
What Is an INCI List?
INCI stands for International Nomenclature of Cosmetic Ingredients. It is a global system of standardised names for cosmetic and personal care ingredients, first developed in the 1970s by what is now the Personal Care Products Council in the United States. The goal was simple: one ingredient, one name, understood by regulators and consumers everywhere.
When you see "green tea extract" printed on the front of a bottle, the INCI list will call it Camellia Sinensis Leaf Extract ? the Latin botanical name for green tea. When a product claims to contain "Vitamin C," the INCI list will tell you exactly which form: Ascorbic Acid, Ascorbyl Glucoside, or Sodium Ascorbyl Phosphate ? each with different stability and penetration properties.
In Malaysia, the National Pharmaceutical Regulatory Agency (NPRA) requires all cosmetic products to display the full INCI ingredient list on the label, as set out in the Guidelines for Control of Cosmetic Products in Malaysia. There are no exceptions. If a product is sold in Malaysia, the INCI list must be there.
Why does this matter for brand founders? Because the INCI list is one of the documents you will need to submit as part of your cosmetic notification to the NPRA. Your OEM manufacturer should provide it as standard ? if they hesitate to share it, that is a red flag.
The Order Is Not Random
Here is the single most important rule about INCI lists: ingredients are listed in descending order of concentration. The ingredient at the top is present in the greatest amount. The ingredient at the bottom is present in the smallest amount.
This is where marketing claims and reality can diverge. If a product is sold as a "Vitamin C Brightening Serum" but Ascorbic Acid appears near the very end of the list ? after the preservative and the fragrance ? the concentration is almost certainly too low to have any clinical effect. The positioning of an ingredient tells you more than the name on the front of the box.
There is one legal exception worth knowing. Ingredients present at 1% or less may be listed in any order, as long as they all appear after the ingredients present above 1%. This is a regulatory allowance that gives formulators some flexibility with minor additives ? but it also means the bottom third of most INCI lists may not be in strict descending order. Do not over-interpret the exact ranking of ingredients that appear late in a long list.
Strong formulation (niacinamide at effective dose):
Aqua, Niacinamide, Glycerin, Butylene Glycol, Sodium Hyaluronate?
Weak formulation (niacinamide as an afterthought):
Aqua, Glycerin, Butylene Glycol, Cetyl Alcohol, Dimethicone, Carbomer, Phenoxyethanol, Niacinamide?
In the second example, niacinamide appears after the preservative ? likely at under 1%. It is probably not doing much.
Learning the Language: Three Naming Conventions
INCI names look intimidating because they mix three different naming systems. Once you recognise each type, the list becomes far less overwhelming.
Latin botanical names are used for plant-derived ingredients. They follow standard binomial nomenclature ? the same system used in biology textbooks. Camellia Sinensis Leaf Extract is green tea. Centella Asiatica Extract is cica (tiger grass). Rosa Canina Fruit Oil is rosehip oil. The Latin name removes any language ambiguity ? every cosmetic chemist and regulator worldwide knows exactly what plant is being referenced.
Chemical or INN names are used for synthetic and isolated compounds. Niacinamide is vitamin B3. Retinyl Palmitate is a form of vitamin A. Tocopheryl Acetate is vitamin E acetate. These often follow IUPAC (International Union of Pure and Applied Chemistry) naming conventions, though internationally accepted common names are also used where established.
Accepted common names are used for certain standardised substances. The most familiar example: Aqua ? Latin for water ? will appear near the top of virtually every water-based skincare product. Colourants are listed using Colour Index numbers, such as CI 77891 for titanium dioxide. Fragrances appear as Parfum or Fragrance as a collective term, with individual allergens disclosed separately where required.
What to Look for as a Brand Founder
When reviewing a formulation from an OEM manufacturer, the INCI list is your quality-control document. Here is a practical checklist.
Position of your hero active. If you are launching a niacinamide serum, niacinamide should appear in the first half of the list ? ideally within the first five to eight ingredients. Effective concentrations for niacinamide sit between 2% and 10%. If it appears after the preservative system, the dose is likely too low to deliver the result you are promising customers.
Form of key ingredients. Not all Vitamin C is equal. Pure Ascorbic Acid is effective but unstable in water. Ascorbyl Glucoside and Sodium Ascorbyl Phosphate are more stable, gentler, and suitable for tropical climates like Malaysia's. Ask your formulator which form they are using and why ? the INCI name will confirm this.
Preservative system. Look for preservatives such as Phenoxyethanol, Benzyl Alcohol, Ethylhexylglycerin, or Caprylyl Glycol. A product with no visible preservative system should be questioned ? unless it is anhydrous (water-free, like a facial oil or a wax-based balm), it needs a preservative to remain safe on shelf.
Fragrance and colourants. By convention, fragrances and colourants always appear at the very end of the INCI list, regardless of concentration. This is a regulatory norm, not an indication of low percentage. If you are developing a fragrance-free product for sensitive skin, confirm with your manufacturer that Parfum does not appear at all ? all even at trace levels.
What This Means for Your Brand
If you are planning to launch a skincare product in Malaysia, your INCI list is not just a regulatory checkbox ? it is a trust signal. Educated consumers, pharmacy buyers, and export distributors now read ingredient lists. A product with a strong, transparent, well-positioned ingredient deck communicates formulation integrity. A product where the hero ingredient appears twelfth in a list of fourteen reads as a marketing exercise rather than a serious formulation.
Before you commit to any production run, request the full INCI list from your manufacturer and review it against your intended product claim. A good OEM partner will share this without hesitation and walk you through the rationale for each ingredient. If the claimed active is not well-positioned, ask for a reformulation. You are the brand owner ? you have every right to understand what is in your product.
At SKCC Laboratories, every formulation comes with a complete, accurate INCI list as part of the Product Information File ? a document required for NPRA cosmetic notification. Our formulation team is happy to explain every ingredient on the list and advise on ingredient positioning for your specific product claim.
Key Takeaways
- INCI stands for International Nomenclature of Cosmetic Ingredients ? a global standardised system for naming cosmetic ingredients, mandatory on all labels in Malaysia.
- Ingredients are listed in descending order of concentration. The first ingredient is present in the highest amount.
- Ingredients at 1% or below can be listed in any order after those above 1% ? so the exact ranking at the end of a list is not always meaningful.
- Plant ingredients use Latin binomial names; synthetics use chemical or INN names; water appears as Aqua.
- The position of your hero active ingredient in the INCI list is a direct indicator of whether the concentration is likely to be effective ? always check it before approving a formulation.
