Natural and Organic Cosmetic Certification: COSMOS, Ecocert and NATRUE
Natural and organic claims sell, and they are also the claims most tightly controlled by third-party schemes. A brand cannot simply describe a product as natural in several markets without substantiation, and the certification schemes define precisely what is and is not permitted. The practical point is that certification is a design constraint that touches formulation, sourcing, packaging and manufacturing, and it is far cheaper to build in from the start than to retrofit.
The Main Schemes
Three names account for most of the market, and they differ in what they require.
- COSMOS. A harmonised standard created by several certification bodies working together. It defines which ingredients are permitted, how they must be produced, minimum natural and organic content thresholds, and rules on packaging and manufacturing. Two levels exist: COSMOS Natural, which requires natural origin but no organic content, and COSMOS Organic, which sets minimum organic percentages that depend on the product type.
- Ecocert. One of the longest-established bodies, and an accredited certifier of the COSMOS standard. Ecocert also operates its own earlier natural and organic specifications, though most new certifications are under COSMOS.
- NATRUE. A label administered by an industry association, with two tiers: Natural Cosmetic and Natural Cosmetic with Organic Portion. NATRUE is stricter than COSMOS on some synthetic ingredients and prohibits some that COSMOS permits.
Other national and private labels exist, and some markets have their own expectations. The choice of scheme should be driven by where the product will be sold and which label the target retailers recognise.
What Certification Changes in the Formula
The permitted ingredient list is the first constraint. Certain preservatives, solvents, chelating agents and processing aids that are routine in conventional cosmetics are restricted or prohibited, and the substitutes often perform differently. This is a formulation consequence, not a paperwork one: a certified formula usually requires a different preservative system, and the sensory profile of a certified product can differ from its conventional equivalent.
Second, the organic percentage thresholds are calculated by a defined method that counts certain ingredients and excludes others. Water and ingredients that are mostly water are typically excluded from the organic calculation, which is why a product that is ninety-five percent water cannot be certified organic simply because it contains an organic extract. The arithmetic decides the label, and it should be modelled before the formula is finalised rather than after.
What It Changes in the Supply Chain
Every ingredient must be sourced from a supplier who can provide certification for that specific material. Not all suppliers offer certified grades, and where they do, the certified grade is usually more expensive and sometimes performs differently. Traceability runs from the finished product back through each ingredient to its origin, and the documentation has to be maintained for the life of the certification.
- Raw material certificates must match the material actually supplied, not a similar grade from the same supplier.
- Any change of supplier for a certified ingredient has to be notified and approved.
- Fragrance is a particular constraint, since certified products require fragrance that complies with the scheme.
What It Changes in Manufacturing
The factory must be certified to produce certified goods, which involves an audit of the site, its cleaning procedures, its documentation and its traceability. The practical consequences are real: cleaning between a conventional and a certified production run must be controlled, and there are rules about which products can share equipment and in what order. This is why not every manufacturer can produce certified goods, and why a brand planning a certified range should confirm the factory's certification status before development begins rather than after the formula is approved.
Packaging and Claims
Certification schemes also set rules on packaging, including recyclability expectations and restrictions on certain materials. The label must carry the certification mark in the prescribed form and comply with the scheme's rules on claims. A brand cannot mix a certified claim on one product with a conventional claim on the same label, and marketing language has to stay within what the certification supports.
Cost and Timeline
The direct costs are certification fees and audit costs, which recur. The indirect costs are higher ingredient prices, a more limited palette, additional documentation and, often, a slightly higher unit cost. The timeline is the part brands underestimate most: sourcing certified materials, reformulating, and completing stability and compatibility work on the new formula takes longer than a conventional development, and the certification audit has to be scheduled.
Deciding Whether to Certify
Certification makes sense where the target market and the retailers reward it and where the brand's position depends on it. It does not make sense as a badge added for its own sake, because the constraints are permanent. A practical first step is to model the formula against the chosen scheme's rules and check the availability and price of certified grades for every ingredient, before committing to the project. OEM COSMETICS ODM manufactures under ISO 22716 and GMP systems and works with certified raw material suppliers, advising brands on scheme requirements and on which formulations are achievable within them.
