CERTIFICATION COSMOS INGREDIENTS

What Does ECOCERT COSMOS Certified Actually Mean?

ECOCERT COSMOS is one of the most rigorous third-party certifications in cosmetics. Here is exactly what it requires — and why it matters for your hair care.

Walk into any beauty aisle and you will see words like natural, botanical, and eco on almost every bottle. Most of them mean nothing. ECOCERT COSMOS certification is different, and understanding why requires knowing what the standard actually demands.

What Is COSMOS?

COSMOS stands for COSMetic Organic and Natural Standard. It was launched in 2011 by five founding certification bodies: BDIH (Germany), Cosmébio (France), ECOCERT (France), ICEA (Italy), and the Soil Association (UK). Today the standard is used in more than 70 countries and is recognised as the benchmark for certified natural and organic cosmetics in Europe.

The standard is independently owned by the COSMOS-standard AISBL, a non-profit association. ECOCERT is one of the bodies that can audit and certify products to the COSMOS standard, which is why you often see the two names together.

What Does It Actually Require?

COSMOS certification is not a logo a brand can apply for by filling out a form. Every product must pass an independent third-party audit conducted by an accredited certification body. The audit covers formulation, ingredient sourcing, manufacturing process, and packaging.

To carry the COSMOS label, a product must meet these requirements:

  • No petroleum-derived ingredients. Mineral oils, petrolatum, paraffins, and PEGs derived from petrochemicals are prohibited.
  • No synthetic fragrances. All scents must come from natural sources.
  • No silicones. Dimethicone and its derivatives are banned.
  • No GMOs. Genetically modified organisms are not permitted at any stage.
  • No parabens, no formaldehyde releasers. Only a restricted list of approved preservatives is allowed.
  • Packaging restrictions. Primary packaging must be recyclable, reusable, or compostable where technically possible.

These are baseline requirements. They apply to every product with a COSMOS label, whether COSMOS Natural or COSMOS Organic.

Two Tiers: Natural and Organic

COSMOS has two certification levels. COSMOS Natural requires that all ingredients come from natural or naturally-derived sources. COSMOS Organic adds strict organic sourcing requirements on top of everything in COSMOS Natural.

For COSMOS Organic rinse-off products (shampoos, conditioners), at least 10% of the total formula by weight must be certified organic ingredients, and at least 95% of the plant-based ingredients in the formula must be organically grown. For leave-on products, the organic threshold rises to 20% of the total formula.

These numbers can sound small until you consider that water, which makes up 60-90% of most rinse-off products, cannot be certified organic. The percentages are calculated on the non-water portion of the formula, making the organic requirements far more demanding than they initially appear.

All NUDA hair care products are certified to the COSMOS Natural standard. Our VIVID Serum is certified to the higher COSMOS Organic standard. You can verify all our certifications on our certifications page.

Who Audits the Products?

This is the part most brands do not talk about. COSMOS certification requires annual third-party audits, carried out by the certifying body, not by the brand itself. Auditors review the full ingredient documentation, supplier certifications, manufacturing records, and finished product formulas. A brand cannot self-declare COSMOS compliance. The badge has to be earned and renewed.

This is precisely why the COSMOS logo on a bottle carries weight that words like natural or clean do not.

Why It Matters for Hair Care Specifically

Hair care products sit on the scalp, skin that is particularly absorbent and in direct contact with the product for the duration of washing. Ingredients that are permitted in conventional formulations, such as certain synthetic preservatives and silicone-based conditioning agents, are excluded from COSMOS formulas. For anyone with a sensitive scalp, colour-treated hair, or a preference for ingredient transparency, this distinction is meaningful.

Frequently Asked Questions

Is ECOCERT the same as COSMOS?

No. ECOCERT is a certification body, an independent organisation that audits products. COSMOS is the standard those products are audited against. ECOCERT was one of the five organisations that created the COSMOS standard in 2011, and ECOCERT is accredited to certify products to the COSMOS standard. When you see "ECOCERT COSMOS Organic" on a product, it means ECOCERT was the body that certified it to the COSMOS Organic standard.

Can a brand use the COSMOS logo without certification?

No. The COSMOS logo is a registered trademark. Using it without a valid, current certification from an accredited body is not permitted. Products are listed on the certifying body's public database, so consumers can verify a brand's certification status directly.

Does COSMOS certification expire?

Yes. Certification requires annual renewal, which means annual audits. A product that passed certification three years ago and has since changed its formula or suppliers must go through the audit process again. There is no permanent or lifetime COSMOS certification.

What is the difference between COSMOS and USDA Organic for cosmetics?

USDA Organic is a United States Department of Agriculture standard primarily designed for food. Some cosmetic brands apply for USDA Organic certification for their products, which requires 95% organically produced agricultural ingredients. COSMOS is a European standard specifically designed for cosmetics, with requirements tailored to cosmetic formulation, restrictions on processing methods, packaging, and cosmetic-specific ingredients. Both are legitimate third-party certifications; COSMOS is more relevant and widely recognised in the UK and EU markets.

Are all NUDA products COSMOS certified?

Yes. Every NUDA product is certified to the COSMOS Natural standard, audited annually by ECOCERT. Our VIVID Serum holds the higher COSMOS Organic certification. Full certification details are available on our certifications page.

What ingredients does COSMOS prohibit that conventional shampoos often contain?

Common ingredients in conventional shampoos that are prohibited under the COSMOS standard include: sodium laureth sulfate (when derived from petrochemicals), dimethicone and other silicones, PEG compounds, synthetic fragrance compounds, petrolatum, and parabens. COSMOS permits only a restricted list of approved preservatives and requires all surfactants to meet defined biodegradability thresholds.
