Chemical in cosmetic goods behind 350,000 heart disease deaths per YEAR
A 'forever chemical' in thousands of cosmetic products could be responsible for over 350,000 heart disease deaths each year, a government-funded study suggests.
Researchers in New York City combed through health and environmental data from 200 countries to measure exposure to di-2-ethylhexyl phthalate (DEHP).
DEHP is a type of phthalate, toxic chemicals used to help scents last longer and in food containers to make them more durable.
Studies have shown they imitate the body's hormones and interfere with the production of - and response to - natural hormones like estrogen and testosterone.
But previous research has also shown that phthalates can cause an immune response that triggers inflammation in the heart's major arteries.
Over time, this inflammation may cause the heart to work harder and increases the risk of heart attack and stroke.
Based on these findings, the researchers estimated exposure to DEHP contributed to over 350,000 deaths worldwide from heart disease every year.
And in the US alone, DEHP was directly linked to one in eight - 10,000 - deaths from cardiovascular disease, America's number one killer that takes more lives than cancer and dementia combined.
The researchers said the study is likely the first to date to calculate the burden of cardiovascular disease directly caused by toxic chemicals.
Sara Hyman, an associate research scientist at NYU Grossman School of Medicine in New York City, said: 'By highlighting the connection between phthalates and a leading cause of death across the world, our findings add to the vast body of evidence that these chemicals present a tremendous danger to human health.'
There are nearly 1million deaths from cardiovascular disease - a group of disorders including coronary artery disease, heart attack and stroke - every year in the US.
The study, published Tuesday in the journal Lancet eBiomedicine, analyzed health data from 200 countries, including the US and UK.
This data included urine samples showing traces of phthalates and mortality data from the US Institute for Health Metrics and Evaluation.
They then used a mathematic model to estimate the likelihood the chemicals played a role.
They found in 2018, the latest data available, 12 percent of all cardiovascular deaths in the US were related to DEHP exposure. This added up to 10,237 deaths.
Additionally, these chemicals were responsible for 316,916 years of 'lost human life' from cardiovascular disease.
Worldwide, India had the highest amount of deaths from DEHP exposure at 103,587. China and Indonesia followed closely behind with 60,937 and 19,761, respectively.
In the UK, DEHP was linked to 947 cardiovascular-related deaths, or just under one in 10.
The researchers believe long-term exposure to phthalates triggers inflammation in arteries in the heart.
Over time, this leads to conditions like atherosclerosis, where plaque builds up in the arteries and restricts blood flow. Eventually, the heart needs to worker harder, leaving it prone to heart attacks and strokes.
Dr Leonardo Trasande, senior study author and professor in the Department of Population Health at NYU Grossman School of Medicine, said: 'Our results underscore the urgent need for global regulations to reduce exposure to these toxins, especially in areas most affected by rapid industrialization and plastic consumption.'
Phthalates are most common in plastics, as they make them pliable and soft and are used in thousands of products, from plastic food wrap to vinyl flooring, garden hoses and shower curtains.
They are also estimated to be in around three-quarters of scented personal care products like deodorants, nail polish, hair gels, shampoos, soaps and lotions.
The fact they are so abundant in beauty goods may partly explain why women consistently have higher levels in their bodies than men.
The chemicals have been associated with fertility issues in both men and women.
One study in the journal Toxicological Sciences, for example, found that female mice exposed in the womb to the same phthalate mixtures detected in pregnant women were born with fertility issues, which they then passed on to their female offspring.
And researchers at the National Institutes of Health (NIH) found that exposure to the fragrance musk ambrette - which contains phthalates - could increase the risk of early puberty in girls, as children and teens have started wearing makeup and perfume at earlier ages.
Earlier puberty in girls has been linked to a complications like increased risk for obesity, heart disease, breast cancer, and psychological problems.
At least nine commercially used phthalates - including DEHP - are still authorized to be in cosmetic products in the US - compared to just one in Europe.
However, some states have tried to crack down on these. California's Prop 65 legislation lists six phthalates - including DEHP - as substances known to cause cancer, birth defects, and reproductive harm.
Phthalates are included in the FDA's list of chemicals the agency is currently reviewing to determine how safe they are to the food supply.
The legislation requires businesses to determine if they need to provide warning labels about safe chemical levels and has established 'safe harbor levels' for some listed chemicals. However, this only applies to one-third of them.
The new study was partly funded by the National Institutes of Health.

Doctor says three toxic household items 'must be thrown away immediately'
A gastroenterologist, Dr Saurabh Sethi, has highlighted the three home items that he claims are the most noxious and insists they should be immediately discarded for health concerns. Topping his list are scented candles. He remarked: "These contain phthalates, which are known to disrupt hormone levels,and cause respiratory issues." Choosing unscented or natural options is better, according to Dr Sethi, who recommends: "Opt for unscented or natural candles made from soy or beeswax." His warning extends to plastic cutting boards too; he asserts: "These can degrade over time, releasing microplastics into your food, which can accumulate in the body. Switch to a wooden one to minimise risk." Lastly, Dr Sethi warns against scratched or damaged non-stick pans, stating: "These contain PFAs, which have been linked to high blood pressure, cholesterol and reproductive issues", reports the Mirror. He advises: "Damaged pans can release these particles into your food. So make sure to either replace these pans as soon as they are scratched or chipped. Or replace those with safer alternatives, such as stainless steel or cast iron." For context, phthalates (pronounced thal-ates) are chemical compounds often added to plastics like polyvinyl chloride (PVC) to enhance their flexibility, strength, and longevity. Frequently called plasticizers, they are common not only in plastics but also in personal care products, household goods, medical instruments, and food packaging. Phthalates, known as endocrine disruptors, can meddle with the body's hormone systems. They have the potential to mimic or block hormones such as estrogen and testosterone, leading to: Inhaling them (like from scented products) may result in: Animal studies suggest some phthalates may encourage tumour development. Some health agencies classify DEHP as possibly carcinogenic to humans. Microplastics are minuscule plastic particles often invisible to the naked eye - and they are considered harmful for both environmental and human health reasons. Microplastics can transport toxic chemicals, either from the plastic itself or absorbed from the environment. These include: These chemicals may interfere with: PFAS stands for Per- and Polyfluoroalkyl Substances - a large group of human-made chemicals (over 10,000 types) used since the 1940s to make products resistant to water, oil, heat, and stains. PFAS, often dubbed "forever chemicals" due to their persistent nature in the environment and human body, are commonly found in a plethora of household items and materials. These forever chemicals make their way into numerous products we encounter daily, such as: Research has highlighted worrying health implications associated with PFAs exposure:

Doctor says toxic household items 'must be thrown away', and you have all three
The common household objects are used every day by millions of people but are packed with dangerous chemicals A doctor has named what he says are the three most toxic household items that 'must be thrown away immediately'. Dr Saurabh Sethi, a gastroenterologist, has urged people to take action as soon as possible. First on the list from Dr Sethi is scented candles. He said: 'These contain phthalates, which are known to disrupt hormone levels,and cause respiratory issues. 'Opt for unscented or natural candles made from soy or beeswax.' Dr Sethi lists plastic cutting boards as being a danger. He says: 'These can degrade over time, releasing microplastics into your food, which can accumulate in the body. Switch to a wooden one to minimise risk.' And last on the list? Scratched or chipped non-stick pans. Dr Sethi explains: 'These contain PFAs, which have been linked to high blood pressure, cholesterol and reproductive issues. 'Damaged pans can release these particles into your food. So make sure to either replace these pans as soon as they are scratched or chipped. Or replace those with safer alternatives, such as stainless steel or cast iron.' Phthalates (pronounced thal-ates) are a group of chemical compounds commonly used to make plastics — especially polyvinyl chloride (PVC) — more flexible, durable, and harder to break. They are often referred to as plasticizers. In addition to plastics, phthalates are also found in personal care products, household items, medical devices, and even food packaging. Phthalates are endocrine disruptors, meaning they can interfere with hormone systems in the body. They can mimic or block hormones like estrogen and testosterone, leading to: Altered reproductive development Reduced sperm count and quality Early puberty in girls Hormone-related cancers (potentially) Some phthalates, like DEHP and DBP, have been linked to: Birth defects Miscarriages Developmental delays in children Testicular toxicity in animals Exposure through inhalation (like from scented products) may cause: Asthma and allergy symptoms Potential immune system effects in children Animal studies suggest some phthalates may promote tumour development. DEHP is classified as possibly carcinogenic to humans by some health agencies. Microplastics are tiny plastic particles often invisible to the naked eye — and they are considered unhealthy for both environmental and human health reasons. Microplastics can carry toxic chemicals, either from the plastic itself or absorbed from the environment. These include: Phthalates and Bisphenol A (BPA) – endocrine disruptors Heavy metals – like lead or cadmium Persistent Organic Pollutants (POPs) – like PCBs or DDT These chemicals may interfere with: Hormonal balance Reproductive health Neurological development Immune function PFAS stands for Per- and Polyfluoroalkyl Substances — a large group of human-made chemicals (over 10,000 types) used since the 1940s to make products resistant to water, oil, heat, and stains. They're sometimes called "forever chemicals" because they don't break down easily in the environment or the human body. PFAS are used in a wide variety of products, including: Non-stick cookware (e.g., Teflon) Waterproof and stain-resistant fabrics (e.g., Gore-Tex, Scotchgard) Fast food wrappers, microwave popcorn bags Cosmetics (especially long-wear or waterproof types) Firefighting foams Carpets, upholstery, and paints PFAs have been linked to: Interference with thyroid function Developmental delays in infants and children Disruption of reproductive hormones Increased risk of kidney and testicular cancer Elevated cholesterol levels Liver damage Suppressed immune function Reduced response to vaccinations (especially in children) Low birth weight Pre-eclampsia Fertility issues

Chemicals used in cosmetics and household goods linked to 350,000 deaths every year, warn experts
Everything you need to know about the chemical - from items it's commonly found in to other possible health effects 'TREMENDOUS DANGER' Chemicals used in cosmetics and household goods linked to 350,000 deaths every year, warn experts CHEMICALS added to household goods and cosmetics could be linked to more than 356,000 global deaths each year, scientists warn. Called phthalates, the chemicals are often added to plastic items like food containers, as well as makeup, shampoo, nail varnish, hair spray and perfume. Advertisement 1 Phthalates are added to some cosmetics as well as household goods Credit: Getty They also crop up in detergents, solvents, plastic toys and bug repellents. These chemicals break down into microscopic particles and are ingested, with studies suggesting that frequent exposure to them could cause health problems. Research has previously linked phthalate exposure to an increased risk of such as obesity, diabetes, fertility issues and even cancer. Now, researchers from NYU Langone Health say hundreds of thousands of global deaths from heart disease could be linked to phthalates. Advertisement They suggested that 356,000 people may have died from phthalate-related heart disease in 2018 alone. Their study focused on a kind of phthalate called di-2-ethylhexyl phthalate (DEHP), which is used to make food containers, medical equipment, and other plastic items softer and more flexible. "The past decade has presented a new and previously unrecognised risk for cardiovascular disease: exposure to plastic polymers and their chemical additives," they wrote in the journal eBiomedicine. "Of particular concern are phthalates, particularly one class of DEHP, which are used to soften polyvinylchloride (PVC) plastics." Advertisement Previous research has suggested that frequent DEHP exposure may trigger an overactive immune response or inflammation in the heart's arteries, which over time is associated with increased risk of heart attack or stroke. They examined the impact of DEHP on global deaths across 200 countries and territories, using health and environmental data, as well as urine samples containing chemical breakdown products left by the plastic additive. The 6 everyday items 'poisoning' you with toxic plastics linked to cancer The authors estimated that DEHP exposure contributed to 356,238 deaths in 2018 among men and women aged 55 to 64. They said this accounted for more than 13 percent of all global deaths from heart disease. Advertisement Lead author Sara Hyman, an associate research scientist at NYU Grossman School of Medicine, said: 'By highlighting the connection between phthalates and a leading cause of death across the world, our findings add to the vast body of evidence that these chemicals present a tremendous danger to human health." While phthalates are widely used across the world, they found people in the Middle East, South Asia, East Asia, and the Pacific were more vulnerable to health effects. Three fourths of the 356,238 deaths occurred in these regions. "Our study provides, to the best of our knowledge, a previously unknown global estimation of the burden of cardiovascular mortality attributable to DEHP exposure," researchers said. Advertisement "The present disease burden model not only quantifies DEHP-related cardiovascular deaths but also highlights significant geographic disparities, showing that regions such as Africa, the Middle East, and South Asia bear the highest burden of DEHP-attributable deaths. "By focusing on plastic production, consumption, and disposal our findings demonstrate the wide-reaching public health implications of DEHP exposure and how plastic-related chemicals disproportionately impact countries on the Asian continent." What you need to know about phthalates Phthalates are chemical compounds mainly used as plasticisers - additives that make plastic flexible. There has been increased focus on phthalates due to their widespread use in our everyday products, and because there are more and more studies that suggest that phthalates may cause long-term adverse health effects. Here are some of the product categories that may contain phthalates: Plastic toys Coatings Cosmetics and personal care Wood finishes Detergents Adhesives Plastic FCMs and other plastic materials Lubricants Solvents Insecticides Building materials India had the highest death count, at 103,587 deaths, followed by China and Indonesia. Researchers said a possible explanation for this could be that these countries face higher rates of exposure to the chemicals, possibly because they are undergoing a boom in plastic production but with fewer manufacturing restrictions than other regions. Advertisement Senior author Dr Leonardo Trasande said: 'There is a clear disparity in which parts of the world bear the brunt of heightened heart risks from phthalates. "Our results underscore the urgent need for global regulations to reduce exposure to these toxins, especially in areas most affected by rapid industrialisation and plastic consumption." Dr Trasande noted that the study doesn't show that that DEHP is the lone or direct cause of heart disease, nor did researchers take into account the possible health risks of other types of phthalates. The researchers also didn't examine other age groups except 55 to 64-year-olds. Advertisement As a result, the overall death toll from heart disease connected to these chemicals is likely much higher, Dr Trasande claimed. Researchers next plan to track how reductions in phthalate exposure may, over time, affect global mortality rates, as well as to expand the study to other health concerns posed by the chemicals, such as premature birth.
