Chemical Profile | Parabens

Parabens are a group of synthetic chemicals used as antimicrobial preservatives to prevent the growth of bacteria, mold, and yeast. Common parabens include methylparaben, propylparaben, ethylparaben, and butylparaben. You can often find parabens on the label by searching for the suffix “-paraben.”

Parabens are found in a wide variety of consumer goods including personal care and beauty products, pharmaceuticals, food packaging, wipes (baby wipes, wet wipes, etc.), cleaning supplies, pet care products, processed foods (though some companies are reformulating), and also some textiles.

The EU has regulations surrounding the use of parabens, including restrictions against the most potent parabens (such as isopropylparaben and isobutylparaben).^[1] Some US states have passed laws banning certain parabens in specific consumer goods. California^[2] and Vermont^[3] have taken measures to ban specific parabens—isopropylparaben and isobutylparaben—from cosmetic products (in Vermont the law also extends to menstrual products). California has additionally banned propylparaben in foods (effective in 2027).^[4]

Parabens are associated with endocrine disrupting activity,^[5][6][7][8] which means that they disturb the fine-tuned functions of the body by mimicking, blocking, or otherwise interfering with hormones. Because the endocrine system plays multiple critical roles in the regulation of the body, its disruption can have wide-ranging impacts, affecting everything from appetite regulation to fertility and more. For example, one 2025 study found a correlation between paraben exposure and altered menopause onset.^[9] In a similar vein, parabens have been associated with precocious puberty, with some parabens increasing the odds of early breast development in girls.^[10] Another 2025 study uncovered a link between parabens and hormone-disruption driven obesity in children.^[11] The reproductive harm caused by parabens was also investigated in a 2023 paper that found that paraben exposure was significantly associated with declining sperm concentration, count, and motility in adult males.^[12] Parabens have even been found to negatively impact metabolic health, with researchers finding that parabens contribute to insulin resistance and drive adverse lipid profiles (e.g., higher triglycerides; lower “good” cholesterol).^[13] Concerns such as these have led The Endocrine Disruption Exchange to flag methylparaben, ethylparaben, and butylparaben as potential endocrine disruptors.^[14]

The repercussions of paraben exposure are broad, and ongoing research continues to investigate their many impacts. Some studies have reported associations between paraben exposure and cancers such as breast cancer^[15][16] and bladder cancer.^[17] Recent studies have explored the emerging patterns between prenatal paraben exposure and neurodevelopmental and behavioral impacts in children. One 2025 study found that exposure to methylparaben during the third trimester of pregnancy is associated with increased behavioral disorders in children,^[18] and a 2026 study found that higher levels of methyl-, ethyl-, and propyl- parabens in pregnant mothers were linked to increased aggression and impulsivity in children by ages 2-4.^[19]

Parabens have also been found in the environment, with one 2026 study finding alarming levels of paraben contamination in groundwater near dumpsites.^[20] Soil contamination from parabens is an ongoing concern, and researchers are seeking to understand the ecotoxicological effects caused as a result. Environmental concerns related to parabens include that they are toxic to fish,^[21] they bioaccumulate in aquatic organisms,^[22] and that their presence in soil can affect the ecological functioning of organisms (such as earthworms) that influence soil quality.^[23]

While parabens, at large, continue to be widespread in the life of the average consumer, a 2025 meta-analysis of 203 publications found that overall global exposure to methylparaben has declined from 2000 to 2024.^[24] Unfortunately, though, the study did conclude that pregnant women and children—two of the most vulnerable populations—were found to have higher levels of exposure compared to non-pregnant adults. It is encouraging to see a decline in the exposure to methylparaben, but questions remain as to the overall decline in parabens as a distinct category. It is likely that much of this shift away from methylparaben is consumer demand and advocacy driven, as awareness has increased regarding the ill effects of parabens. As often happens, manufacturers tend to make what is known as regrettable substitutions where they replace one harmful ingredient with another that is similar and likely has the same or only slightly less toxic effects. Despite the study’s evidence of decline in specific parabens like methylparaben, parabens generally remain nearly ubiquitous in modern-day life, leading to consistent and often high levels of exposure. Considering the frequency of exposure, it will be important to understand the impact of chronic exposure rather than acute exposures alone in order to get a full picture of the health effects going forward.^[25] 

• Shop MADE SAFE and MADE WISE Certified products.
• Read labels to avoid parabens. They can often be identified by the suffix “-paraben” on the label. Examples of common parabens are:
  • Methylparaben
  • Propylparaben
  • Ethylparaben
  • Butylparaben
  • Less common, but still used in some cases: isopropylparaben and isobutylparaben
• Look for “paraben-free” on the product packaging or label. Thanks to consumer demand and state-specific legislation, many companies have started to move away from parabens. In these cases, you might see a product labeled as “paraben-free.” Be careful to maintain your discerning label-reading eye though—just because something is free of parabens does not automatically imply that the rest of the formula is safer. “Paraben-free,” while an important step, can also be a great way to greenwash an otherwise abysmal ingredient list.
• Go fragrance free wherever possible. Many fragrance formulas rely on parabens as antimicrobials and stabilizers. If you do use a fragranced product, use one that discloses all of the fragrance ingredients and/or references a third-party certification program like MADE SAFE or MADE WISE that requires full ingredient disclosure.
• Eat more whole, unprocessed foods. This is the easiest way to eliminate possible exposures to parabens found in processed foods and food packaging.
• Find products that use safer preservatives such as: citric acid, sorbic acid, gluconolactone, potassium sorbate, and caprylhydroxamic acid.
