Study of contaminants in natural cosmetics.
Article in International journal of occupational medicine and environmental health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesCosmetic products placed on the market should be safe for both the consumer and the professional user. Safety monitoring of cosmetics is regulated by law in the European Union. In practice, there are 3 levels of safety assessment: the manufacturer, a qualified safety assessor and the competent authority, which in Poland is the State Sanitary Inspectorate, responsible also for official surveillance and product sampling. To identify the occurrence of threats to human health from selected chemical and biological factors based on cosmetic products distributed in Podkarpackie Province in 2023. MATERIAL AND
methodsThe material was 40 randomly selected samples of cosmetic products for body, face and hair. Formaldehyde was determined by spectrophotometry, silver(I) nitrate (AgNO₃) by spectrophotometric methods, and mercury by atomic absorption spectrometry with an amalgamation technique. In addition, the total number of aerobic mesophilic microorganisms and
resultsFormaldehyde content was <0.005% in all tested cosmetics for skin and hair cleansing. Mercury ranged from 0.0000001±0.00000001% to 0.0000002±0.00000003%. Silver(I) nitrate(V) in eye products was <1.57%. The total count of aerobic microorganisms was <10 CFU/g, and
conclusionsCosmetic products tested in 2023 showed formaldehyde below the detection limit (<0.005%), while mercury, AgNO₃, and microbiological contaminants were within legal limits. Results apply only to the analyzed samples and should be interpreted considering current formaldehyde limits in cosmetics (0.001%, 10 ppm). Int J Occup Med Environ Health. 2026;39(2):138-48.
