A small European test of 53 products found no significant difference in paraben levels between \"green\" and conventional ones [6]. The ingredient list tells you more than the front label.","mediumText":"How it works\n\nThe legal picture\n\nIn the US, the law does not require cosmetic labeling to have FDA approval before products reach the market, and FDA keeps no list of approved claims. Claims must be truthful and not misleading, and the Federal Trade Commission polices advertising [5]. FDA's list of prohibited or restricted cosmetic ingredients had 11 entries at its 2022 update, and apart from color additives, products and ingredients do not need FDA approval [7]. The EU Cosmetics Regulation bans substances listed in its Annex II, which runs to well over a thousand numbered entries [8]. A 2022 US law, the Modernization of Cosmetics Regulation Act (MoCRA), added registration, product listing, safety substantiation, adverse-event reporting and recall authority, and told FDA to set fragrance-allergen labeling rules [9].\n\nWhat testing finds\n\nSmall studies have not found that \"green\" or \"natural\" claims predict fewer questionable ingredients. In 19 \"green\" and 34 conventional products, paraben levels did not differ significantly, and parabens were found in 43 products even though only four named them on the label [6]. Among EU safety alerts for products declared natural, 64% involved unauthorized substances [4]. That is a flagged sample, so it shows what can go wrong, not how often.\n\nNatural is not hypoallergenic\n\nFDA does not define \"hypoallergenic\" either, and warns not to assume such a product will avoid allergic reactions [3]. Botanical extracts are a recognized cause of contact allergy, including tea tree oil, peppermint, lavender and lichens [10]. In 62,354 patch-tested patients, 1.4% reacted to an essential oil but to none of the standard fragrance markers [2].\n\nPreservatives are a trade-off. Products with water can grow microbes, and 12% of flagged \"natural\" products were contaminated [4]. But any preservative can cause problems. Methylisothiazolinone (MI) was allowed as a stand-alone cosmetic preservative in 2005 and caused an allergy epidemic [11].\n\nHow to read a label\n\n1. Ignore the front claims; find the ingredient list.\n2. Look for \"Fragrance (Parfum)\" if you are fragrance-sensitive [1].\n3. Treat seals and \"clean\" retailer lists as private programs with their own rules; FDA has no list of approved claims [5].\n\nFor specific ingredients, see Parabens, Fragrance and Perfume and Hidden Chemicals in Your Daily Routine.","deepText":"The evidence in detail\n\nRules and gaps\n\nFDA states that it has not defined \"natural\" for cosmetics, does not define \"hypoallergenic\", and that the source of an ingredient does not determine its safety [3]. Its page on prohibited and restricted ingredients lists 11 items, including bithionol, chloroform, hexachlorophene, mercury compounds, methylene chloride and vinyl chloride [7]. MoCRA's changes include facility registration, annual product listing, serious adverse-event reports within 15 business days, and mandatory recall authority when a company refuses a voluntary recall in serious cases. A rule to test talc for asbestos was proposed in December 2024 and withdrawn in November 2025. FDA published a report on PFAS in cosmetics on 29 December 2025 [9].\n\nTesting \"green\" and \"natural\"\n\nEuropean researchers analyzed 19 green and 34 conventional personal care products from one store for seven parabens, triclocarban and triclosan. There was no significant difference in concentrations. Parabens turned up in 43 of 53 products, at microgram-per-gram levels in seven, and one mascara exceeded the EU limit for methylparaben. Parabens banned in the EU were detected at low levels in 70% of products. Modeled daily intake was about ten times higher for people using only conventional products, which suggests labels may carry some signal even though measured concentrations did not differ. The sample came from one store and was small [6].\n\nA review of EU Safety Gate reports (2005 to 2023) on cosmetics declared natural found 64% contained unauthorized substances, 14% exceeded authorized limits and 12% had microbial contamination. Butylphenyl methylpropional (lilial) was the dominant ingredient in several product categories. Because Safety Gate lists only products that regulators flagged, the percentages describe flagged products, not natural cosmetics overall [4].\n\nAn analysis of 213 products across 50 product types found 55 compounds, many not on the label. Alternative products chosen by purchasing criteria could avoid some targets, such as synthetic fragrance, but not all [12].\n\nNatural ingredients and allergy\n\nIn a retrospective analysis of 62,354 patients in North America and Central Europe, 11,568 (18.6%) reacted to at least one fragrance marker or essential oil, and 857 (1.4%) reacted to an essential oil but no marker. In Central Europe, ylang-ylang was positive in 2.4% of patients, sandalwood in 1.4% and jasmine in 1.4%; in North America, peppermint in 0.9%. Oxidized tea tree oil was positive in only 0.3% of North American patients but accounted for 45% of those who reacted to an oil and no marker. Because essential oils used as fragrance need not be labeled, finding the cause can be hard [2]. A review lists Compositae plants, tea tree oil, peppermint, lavender, lichens and henna as sensitizers. The culprit may be the botanical or another ingredient in the same product [10].\n\nPreservatives and unintended consequences\n\nA Danish clinic tested 12,494 consecutive patients from 2005 to 2019, and 3.0% were sensitized to MI. The EU banned MI in leave-on cosmetics in 2017. The share of MI-allergic patients whose exposure came from leave-on cosmetics then fell from 24.8% in 2010 to 2013 to 6.2% in 2017 to 2019, though overall prevalence had not returned to pre-epidemic levels [11].\n\nWhere the evidence is thin\n\nThese studies are small, European, and often drawn from flagged or clinic populations. They show that \"natural\" and \"green\" claims do not guarantee fewer problem ingredients. They do not show that natural products are more dangerous. Many are fine, and some conventional products are well made.\n\nBottom line\n\nConfidence 3 of 5. The regulatory facts are clear: these words are marketing, not standards. Product testing supports skepticism but is limited. A label with a short, readable ingredient list and no ingredients you react to is a better guide than any front-of-pack claim.","deepTruncated":false,"references":[{"id":"1","title":"Cosmetic Ingredient Names","authors":"U.S. Food and Drug Administration","year":2022,"journal":"FDA","url":"https://www.fda.gov/cosmetics/cosmetics-labeling/cosmetic-ingredient-names"},{"id":"2","title":"Positive Patch-Test Reactions to Essential Oils in Consecutive Patients From North America and Central Europe","authors":"Warshaw EM, Zug KA, Belsito DV, et al.","year":2017,"journal":"Dermatitis","pmid":"28614106","url":"https://pubmed.ncbi.nlm.nih.gov/28614106/"},{"id":"3","title":"Using Cosmetics Safely","authors":"U.S. Food and Drug Administration","year":2024,"journal":"FDA","url":"https://www.fda.gov/cosmetics/resources-consumers-cosmetics/using-cosmetics-safely"},{"id":"4","title":"Potential side effects of toxic and restricted substances found in cosmetics declared to be of natural origin","authors":"Koncz D, Nemeth MA, Pallagi E, et al.","year":2026,"journal":"Front Public Health","pmid":"42245339","url":"https://pubmed.ncbi.nlm.nih.gov/42245339/"},{"id":"5","title":"Cosmetics Labeling Claims","authors":"U.S. Food and Drug Administration","year":2022,"journal":"FDA","url":"https://www.fda.gov/cosmetics/cosmetics-labeling/cosmetics-labeling-claims"},{"id":"6","title":"Parabens and antimicrobial compounds in conventional and \"green\" personal care products","authors":"van der Schyff V, Suchánková L, Kademoglou K, et al.","year":2022,"journal":"Chemosphere","pmid":"35183580","url":"https://pubmed.ncbi.nlm.nih.gov/35183580/"},{"id":"7","title":"Prohibited & Restricted Ingredients in Cosmetics","authors":"U.S. Food and Drug Administration","year":2022,"journal":"FDA","url":"https://www.fda.gov/cosmetics/cosmetics-laws-regulations/prohibited-restricted-ingredients-cosmetics"},{"id":"8","title":"Regulation (EC) No 1223/2009 of the European Parliament and of the Council on cosmetic products","authors":"European Parliament and Council of the European Union","year":2009,"journal":"Official Journal of the European Union","url":"https://eur-lex.europa.eu/eli/reg/2009/1223/2025-09-01/eng"},{"id":"9","title":"Modernization of Cosmetics Regulation Act of 2022 (MoCRA)","authors":"U.S. Food and Drug Administration","year":2026,"journal":"FDA","url":"https://www.fda.gov/cosmetics/cosmetics-laws-regulations/modernization-cosmetics-regulation-act-2022-mocra"},{"id":"10","title":"Allergic contact dermatitis to plant extracts in cosmetics","authors":"Jack AR, Norris PL, Storrs FJ","year":2013,"journal":"Semin Cutan Med Surg","pmid":"24175401","url":"https://pubmed.ncbi.nlm.nih.gov/24175401/"},{"id":"11","title":"The epidemic of contact allergy to methylisothiazolinone-An analysis of Danish consecutive patients patch tested between 2005 and 2019","authors":"Havmose M, Thyssen JP, Zachariae C, et al.","year":2021,"journal":"Contact Dermatitis","pmid":"33043989","url":"https://pubmed.ncbi.nlm.nih.gov/33043989/"},{"id":"12","title":"Endocrine disruptors and asthma-associated chemicals in consumer products","authors":"Dodson RE, Nishioka M, Standley LJ, et al.","year":2012,"journal":"Environ Health Perspect","pmid":"22398195","url":"https://pubmed.ncbi.nlm.nih.gov/22398195/"}],"wordCount":1054,"source":{"path":"src/content/topics/clean-beauty-and-greenwashing/what-clean-natural-and-non-toxic-labels-mean.md"},"citeAs":"“What do 'clean,' 'natural,' and 'non-toxic' on a label actually mean?.” What's Healthy and Why. https://whatshealthyandwhy.com/clean-beauty-and-greenwashing/what-clean-natural-and-non-toxic-labels-mean","notice":"General information backed by peer-reviewed research, not medical advice."}
