Phthalates in Coconut Oil
A Hidden Toxin in Your Kitchen

Coconut oil has been widely embraced as a healthy alternative to seed oils, a staple in many kitchens for cooking, baking, and even skincare. It is praised for its stable saturated fat content, high smoke point, and ability to provide quick, clean-burning energy. However, recent testing has raised serious concerns about toxic contaminants in coconut oil.
A recent investigation by Mamavation found that all seven coconut oil brands tested contained phthalates, with some brands reaching contamination levels as high as 1,300 parts per billion (ppb). Phthalates, a class of endocrine-disrupting chemicals, have been linked to hormone imbalances, infertility, metabolic disorders, and developmental issues. This discovery forces consumers to reconsider which brands of coconut oil are truly safe and what steps can be taken to reduce exposure to these hidden toxins.[1]
What Are Phthalates and Why Are They Harmful
Phthalates are a group of industrial chemicals used to make plastics more flexible and durable. They are found in countless consumer products, from food packaging to cosmetics and even medical devices. These chemicals leach into food and beverages when stored in plastic containers, especially when exposed to heat.[2]
The most concerning aspect of phthalates is their ability to disrupt the endocrine system. These chemicals mimic hormones in the body, leading to a range of long-term health effects. Studies have linked phthalate exposure to:
- Reduced testosterone levels in men, which can affect sperm quality and reproductive health
- Increased infertility rates in women due to hormone disruption
- Impaired thyroid function, leading to metabolic and energy imbalances
- Developmental issues in infants and children exposed in utero
- Higher risks of obesity, insulin resistance, and metabolic disorders
Phthalates are not easily broken down by the body, meaning they accumulate over time. Chronic exposure increases the risk of serious health issues, making it crucial to avoid these chemicals whenever possible.
How Do Phthalates Contaminate Coconut Oil
Coconut oil, in its natural state, does not contain phthalates. The contamination occurs at several points during manufacturing, processing, and storage. The most common sources of phthalate contamination include:
- Processing Equipment – Many industrial food processing facilities use plastic tubing, plastic-lined storage tanks, or plastic-coated machinery. When coconut oil is heated and passes through these systems, it can absorb phthalates from the plastic materials.
- Storage Containers – Before being packaged for sale, coconut oil is often stored in large plastic containers, where it can leach phthalates over time, especially in high temperatures.
- Plastic Packaging – Many brands sell coconut oil in plastic jars or bottles. Over time, chemicals from the plastic can migrate into the oil, particularly when stored in warm environments or exposed to sunlight.
- Transportation and Warehousing – Coconut oil is often transported in bulk containers that may be lined with plastic. If these containers are exposed to fluctuating temperatures, it increases the likelihood of chemical leaching.
Which Coconut Oil Brands Are the Most and Least Contaminated
Mamavation’s independent testing of coconut oils revealed significant variations in contamination levels between brands. The brand with the lowest levels of phthalates was Dr. Bronner’s coconut oil, which showed significantly lower contamination than others. Meanwhile, several brands contained levels as high as 1,300 ppb, raising concerns about the safety of even high-quality organic coconut oils.
While a full list of brands has not been disclosed in detail, the findings highlight the importance of choosing coconut oil that has undergone rigorous testing and is packaged in safe materials.
How to Choose a Non-Toxic Coconut Oil
To minimize phthalate exposure while still enjoying the benefits of coconut oil, consumers should follow these guidelines when selecting a brand:
- Opt for organic, cold-pressed coconut oil – Cold-pressed oils are extracted without high heat, reducing the likelihood of phthalate contamination from processing equipment. Expeller-pressed oils are more likely to be exposed to heat, increasing the risk.
- Choose glass packaging over plastic – Coconut oil stored in glass is far less likely to contain phthalates, as glass is non-porous and does not leach chemicals into food.
- Look for brands that provide transparency – Some companies conduct third-party testing for contaminants and share their results. Choosing brands that disclose their safety testing can help ensure a cleaner product.
- Store coconut oil properly – Even if your coconut oil comes in plastic packaging, transferring it to a glass container immediately after purchase can reduce prolonged exposure to plastic. Keeping it in a cool, dark place will further limit potential chemical leaching.
Is Coconut Oil Still a Healthy Choice
Despite concerns about phthalate contamination, coconut oil remains a beneficial fat when sourced properly. It contains medium-chain triglycerides (MCTs), which provide fast-absorbing energy and support brain function. It is also highly stable when heated, making it one of the safest cooking oils available.
However, the presence of phthalates in certain brands means consumers must be more selective. Switching to brands with lower contamination levels and prioritizing glass-packaged, cold-pressed coconut oil can help ensure you get the cleanest version of this popular cooking fat.
Final Thoughts
Coconut oil has earned a reputation as a health food, but recent testing shows that phthalates have contaminated nearly every brand on the market. These chemicals disrupt hormone balance, impair reproductive health, and contribute to metabolic disorders. While avoiding phthalates entirely may be impossible, consumers can minimize exposure by choosing cold-pressed, glass-packaged coconut oils from brands that prioritize purity.
Making informed choices about the products in your kitchen is one of the best ways to reduce toxic exposure and protect long-term health. Before you reach for that jar of coconut oil, check the label, packaging, and brand transparency. These small choices can make a big difference in lowering your toxic load and ensuring that the foods you rely on for health are truly safe.
