Which cosmetic labels guarantee the absence of endocrine disruptors? The guide to choosing safely

Parabens, phthalates, chemical UV filters… all endocrine disruptors still found in many cosmetic products, and increasingly causing concern.

For those concerned about their health, one question arises: what reliable markers help avoid these risky ingredients?

While there is no label exclusively dedicated to endocrine disruptors, some organic or natural labels impose very strict specifications that ensure the absence of most, if not all, known or suspected endocrine disruptors.

 

 

4 reliable labels against endocrine disruptors at a glance

Before going into details, here are the four most reliable labels today to avoid endocrine disruptors in cosmetics:

• Cosmébio / COSMOS: Recognized standard, independent controls, exclusion of major endocrine disruptors (parabens, phthalates, chemical UV filters…).
• Nature & Progress Mention: Very strict charter, no synthetic ingredients, artisanal and ethical approach.
• NATRUE: Rigorous international label, broad exclusion of endocrine disruptors and controversial ingredients, independent audits.
• EU Ecolabel: Official label of the European Union, strict exclusion of identified endocrine disruptors, independent certification, high requirements for ecotoxicity and safety.

 

 

How does cosmetic labeling work?

 

Behind the scenes of a cosmetic label

To fully understand what a label guarantees, it is essential to distinguish three complementary roles:

1. The label holder

It is the organization (often associative or private) that defines the charter or specifications. It sets the criteria to be met (composition, ingredient origin, manufacturing process, exclusions…).

Examples: Cosmébio, NATRUE…

2. The technical standard

In some cases (notably at the European level), several label holders come together around a common standard, such as the COSMOS standard. This is a set of harmonized technical rules, recognized internationally.

3. The certification body

It is an independent body accredited to carry out compliance audits. It regularly checks formulas, ingredients, traceability... and issues the official certification. Without it, no label can be applied.

Examples: Ecocert, Cosmécert, Bureau Veritas, ICEA…

 

Certification: a voluntary, paid, and often cumulative choice

Getting a cosmetic product certified is neither mandatory nor free. Brands must join the label (often through an annual fee), and fund audits carried out by an independent certification body.

When a brand wants to display multiple labels (for example COSMOS and NATRUE), it must pay fees for each one, with separate procedures and inspections. Brands choose to certify their products, or even their brand, to:

• Offer concrete and objective guarantees to consumers;
• Stand out in a market saturated with unverified claims;
• Highlight a strong ethical, environmental, or health commitment.

An unlabeled product can still meet the technical criteria of a label, or even exceed them. For editorial, budgetary, or logistical reasons, some brands prefer to formulate "clean" without formal certification, which is why it remains important to learn how to decode the INCI list on labels.

 

Marketing claims: clearly distinguish fact from fiction

Be cautious though: the absence of a label does not necessarily mean a questionable formulation, but it is important not to be misled by packaging claims like "paraben-free," "clean beauty," "natural," "hypoallergenic"... These reassuring words are generally unregulated and can be misleading.

A statement like "free from endocrine disruptors" has no legal value as such. It may only concern a single ingredient, or a single type of endocrine disruptor (for example estrogenic disruptors, but not androgenic or thyroid ones), and leave room for other equally controversial disruptors.

Similarly, the term "clean beauty," very trendy, is not regulated by any independent body: each brand defines for itself what it means by "clean."

 

 

The most demanding cosmetic labels regarding endocrine disruptors

Even though endocrine disruptors are receiving increasing attention from health authorities, regulations remain incomplete. Some substances are banned, others are under evaluation, but many still fall outside the legal framework.

This is notably the case for certain substances used in conventional perfumes, such as phthalates, still allowed despite concerning health signals. To understand how these components affect our hormonal balance and how to avoid them, discover our comprehensive report on endocrine disruptors in perfumes.

This is where labels truly matter. In the absence of a label specifically dedicated to endocrine disruptors, you can rely on the strictest organic or natural certifications: they go beyond regulations by excluding many concerning ingredients suspected of affecting the hormonal system.

The strength of these labels lies in:

• stringent specifications,
• regular independent inspections,
• great transparency.

Here is an overview of the most reliable to minimize — or even eliminate — exposure to endocrine disruptors.

 

Comparison chart of the most demanding labels regarding EDCs

Label / Mention	Type	Range	Prohibited EDC ingredients	Control & certification	Geographical scope	To remember
COSMOS / Cosmébio	Standard + Association label	Product	Excludes all recognized and suspected EDCs (parabens, phthalates, chemical UV filters…)	Regular audits by accredited bodies (Ecocert, Cosmécert…)	International	Solid and internationally recognized standard; Cosmébio adds an ethical association commitment
Nature & Progrès	Association mention (Participatory Guarantee System)	Entire brand (products + overall approach)	Excludes all recognized and suspected EDCs, ultra-precautionary approach	Participatory control (SPG) by peers and local consumers (no external audit)	France	Very strict and activist association mention, artisanal, ethical, and local approach
NATRUE	International certification label	Product and brand (minimum 75% of the range)	Excludes all recognized or suspected EDCs (REACH, SIN lists)	External audits by approved independent bodies	International (mainly Europe)	Demanding international label, comprehensive "clean" vision, excellent credibility
EU Ecolabel	Official European public label	Product	Excludes all recognized endocrine disruptors (according to REACH, BPR, PPPR) and many suspected ones (parabens, phthalates, chemical UV filters…)	Certification by approved independent bodies, audits and INCI control	European Union	Regulated label, strict on endocrine disruptors and ecotoxicity, overseen by the European Commission

 

Cosmébio & COSMOS standard

Created in 2002, Cosmébio is a pioneering French association. Originally with its own standard, it adopted the European COSMOS standard in 2017, co-founded by several European labels including Cosmébio (with Ecocert, BDIH, ICEA, and the Soil Association).

COSMOS has two certification levels:

• COSMOS Natural: natural formulation, no organic requirement.
• COSMOS Organic: minimum 20% organic in the finished product (10% for rinse-off products).

Both prohibit parabens, phthalates, silicones, PEGs, chemical UV filters, nanoparticles, etc.

To display the Cosmébio logo, a brand must:

• Be COSMOS certified (for one of its two certification levels, Natural or Organic) by an independent certification body (Ecocert, Cosmécert...);
• Join the Cosmébio association.

This dual commitment strengthens the credibility of the products, both technically (COSMOS) and ethically (Cosmébio).

 

Nature & Progrès

Created in 1964, Nature & Progrès is not a label but an associative certification, based on a Participatory Guarantee System (PGS). This evaluation is carried out directly by member producers and consumers, without a third-party certification body.

It requires the exclusive use of ingredients from organic farming or controlled wild harvesting, and completely excludes GMOs, petrochemical derivatives, and all recognized or suspected endocrine disruptors (parabens, phthalates, silicones, chemical UV filters…).

It is one of the strictest certifications in the cosmetics sector, especially appreciated by artisanal brands committed to ethical and local practices.

 

NATRUE

European label founded in 2007, NATRUE prohibits any petrochemical substances or those suspected of endocrine effects.

Like COSMOS, this label has two levels of certification:

• Natural cosmetics (natural formulas, with very low tolerance for nature-identical ingredients).
• Organic cosmetics (95% organic in the natural portion).

It requires certification of at least 75% of a brand’s products. Audits are conducted by accredited organizations.

 

EU Ecolabel

An official European Union label, the EU Ecolabel has applied to cosmetics since 2021. It bans all identified endocrine disruptors according to REACH and other European regulations, as well as many suspected substances (parabens, phthalates, chemical UV filters…). Certification is provided by independent bodies with regular audits.

The label also imposes strict criteria for biodegradability, aquatic toxicity, and proven efficacy. Public, transparent, and recognized throughout the EU, it offers a reliable guarantee of safety and eco-responsibility for cosmetic products.

 

 

There is no label dedicated to guaranteeing the total absence of endocrine disruptors in cosmetics; however, some guidelines allow you to act consciously. As we have just seen, labels, as well as certain particularly strict claims, certify greater protection compared to current regulations. They exclude not only recognized substances but also those that are concerning or controversial.

Vigilance is all the more necessary for sensitive groups. For example, limiting exposure to endocrine disruptors during pregnancy is crucial to protect fetal development.

Beyond the composition aspect, labels cover various aspects of cosmetic production: local sourcing, working conditions, special efforts for the environment… and they also save you a lot of time by easily identifying products that align with your values.
