Phthalates are plasticizers in consumer products that raise health concerns due to endocrine-disrupting properties.
Phthalates are a group of synthetic chemicals primarily used as plasticizers to enhance the flexibility, transparency, and durability of plastics. They are also found in solvents and fragrances in numerous consumer products. Exposure occurs mainly through ingestion, inhalation, and dermal absorption. Due to their endocrine-disrupting properties, phthalates pose significant health risks, including reproductive and developmental toxicity, respiratory problems, and potential links to certain cancers. Therefore, avoiding phthalate-containing products is crucial, especially for pregnant women, infants, and young children.
Key Information
Outside Body Harmful Score
Common Dosage
N/A - Phthalates are not intentionally ingested or used therapeutically.
Source Type
synthetic
Production Process
Phthalates are produced through the esterification of phthalic anhydride with various alcohols. The specific alcohol used determines the type of phthalate produced (e.g., di(2-ethylhexyl) phthalate (DEHP) uses 2-ethylhexanol). This reaction is typically catalyzed by an acid.

Outside BodyPossible Side Effects
Respiratory issues include a range of symptoms such as shortness of breath, wheezing, and coughing, potentially exacerbating pre-existing conditions. The severity varies and may require medical intervention.
Potential Carcinogenic Effects indicate an increased risk of cancer development due to a substance or treatment. This risk depends on various factors like dosage, duration, and individual predisposition, requiring careful assessment and monitoring.
Endocrine disruption involves interference with the endocrine system by chemicals, leading to hormonal imbalances and a variety of adverse health effects, including developmental abnormalities, reproductive problems, and increased risk of certain cancers.
Reproductive toxicity encompasses a range of adverse effects on reproductive health and development, including impaired fertility, adverse pregnancy outcomes, and developmental abnormalities in offspring. The severity and manifestation vary depending on the causative agent, exposure parameters, and individual susceptibility.
Phthalate exposure during prenatal and early childhood can disrupt brain development, potentially leading to neurodevelopmental disorders and behavioral problems like ADHD and autism. The interference arises through disruptions to hormone signaling and altered brain structure.
Some studies suggest a potential link between phthalate exposure and an increased risk of certain cancers, possibly through endocrine disruption or other mechanisms. However, more research is needed to confirm this association.
Scientific Evidence
Key scientific sources and studies include research from organizations such as the National Institute of Environmental Health Sciences (NIEHS), the Environmental Protection Agency (EPA), and various peer-reviewed scientific journals focusing on toxicology and environmental health. Specific studies have investigated the effects of phthalates on reproductive health, respiratory function, and cancer risk.
