Environmental Health Perspectives Publishes Research Finding Pervasive Leaching of Chemicals with EA from Plastic Products That Can Be Averted

MARCH 2, 2011 – (Austin, TX) – Environmental Health Perspectives (EHP), a peer-reviewed journal published by the National Institute of Environmental Health Sciences, today published a major scientific article from researchers at PlastiPure, CertiChem, and Georgetown University, focused on quantifying and addressing the potential health issue of estrogenic activity (EA) in plastic products. The results of this study indicate that the large majority of commercially available BPA-free plastic materials and products readily leach chemicals having EA. Leaching increases when products are subjected to common-use stresses such as dishwashing, microwaving and sunlight.

There is currently great scientific concern about the effects of endocrine disrupting chemicals (EDCs). Chemicals with EA are believed to constitute the largest group of EDCs and have been linked to adverse health effects such as birth defects, reproductive cancers, and behavioral and learning disorders. While the estrogenic chemical BPA is widely known by the public, it is less well known that thousands of other chemicals are suspected to have EA. The EHP paper is groundbreaking in its quantification of levels of EA across multiple BPA-free materials and consumer plastic products, which until PlastiPure’s research have been suspected, but largely unmeasured.

“Almost all commercially available plastic products we sampled, independent of the type of base material, product, or retail source, leached chemicals having reliably detectable EA, including those advertised as BPA-free,” said Mike Usey, CEO of PlastiPure. “In some cases, BPA-free products released chemicals having more EA than BPA-containing products.”

In this study, all types of plastic materials often tested positive for leaching of chemicals having EA, including those manufactured from polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET). Bio-resins, such as several polylactic acid (PLA) resins and products, also showed easily detectable EA. In addition, materials specifically targeted and used as replacements for BPA-containing polycarbonate (PC), such as polyethylene terephthalate glycol (PETG) and polyethersulfone (PES), often leached chemicals having EA levels equivalent to or above those found leaching from BPA-containing PC.

The issue of chemicals with EA leaching from plastics is made worse by methods used to process or decorate plastics with a large variety of additives, colorants, processing aids, and inks. Data from the EHP paper show that all categories of plastic products tested positive for EA, including baby bottles, water bottles, rigid food packaging, bags, deli containers and flexible wrap. In total, 92 percent of individual plastic product samples tested positive for EA even when not exposed to common-use stresses.

Plastics have many ecological advantages—they are light weight and recyclable, and have low energy consumption for manufacture and transport—and they enable innovations that improve life for most people. Plastics should and will continue to be used widely, but should also immediately be made safer with technologies PlastiPure has developed and licensed for formulating, processing and certifying plastics to be EA-Free. Plastic products made using PlastiPure-Safe™ EA-Free technologies can be made for equivalent costs compared to conventional products that leach chemicals with EA.

“Our research and patents provide methods to quickly design, manufacture and certify safe plastic materials for applications in a wide range of industries including food and beverage, infant feeding, personal care, cosmetics, medical supply, pharmaceutical, toys, animal feed, and more,” said Usey.

Company Will Accelerate Development of EA-Free Materials and Products

(Austin, TX) – PlastiPure, a safe plastics technology company, announced today that it has received two grants from the National Institute of Environmental Health and Safety (NIEHS), a division of the NIH, and an additional grant from the National Science Foundation (NSF). Collectively the grants fund formulation of a replacement for polycarbonate that is free of estrogenic activity (EA-Free), creating flexible food packaging that contains no EA, and developing a verifiably EA-Free baby bottle.

“These NIEHS and NSF funds continue to validate our innovative technology and will allow us to expand our development of PlastiPure-Safe™ EA-Free materials and products,” said Mike Usey, PlastiPure CEO. “Consumers want the safest, most sustainable, and most versatile goods possible. PlastiPure’s certified EA-Free products are vastly superior to current market solutions that use BPA-free plastics, glass, or metal materials, providing families with healthy, green, and convenient solutions.”

In addition to the estrogenic chemicals BPA and phthalates, hundreds of other chemicals having EA are used in plastics manufacturing.  Health issues associated with EA include birth defects, reproductive cancers, and behavioral and learning disorders.

In recent testing of 15 premium brand BPA-free baby bottles, PlastiPure findings show that all tested positive for significant levels of EA with 8 at levels comparable to BPA-containing polycarbonate. Clearly BPA-free does not mean EA-Free.

Recently, PlastiPure has successfully introduced PlastiPure-Safe™ resins (TOPAS® COC PlastiPure-Safe™ grades) and certified EA-Free products (Water Geeks and Hydrapak Purebot™ water bottles). With new product partner ReliaBrand, PlastiPure soon will be launching additional EA-Free™ products such as baby bottles, medical devices, food storage containers and multilayered bags under the Adiri, ReliaDose, ReliaWare, and ReliaWrap brands .

“Our extensive research has enabled us to identify and replace hundreds of chemicals that contain EA without significantly impacting material properties, processing methods, or tooling,” said Usey. “This allows PlastiPure to produce unique EA-Free products at competitive costs.”

PlastiPure in Agreement to Develop and License EA-Free Products
for Adiri, Water Geeks, ReliaDose, ReliaWrap, and ReliaWare

(Austin, TX) – PlastiPure, a safer-plastics technology company, has announced a partnership with ReliaBrand to license infant feeding, sports bottle, food packaging, and medical products free of harmful chemicals that cause estrogenic activity (EA).  Chemicals with EA have been strongly linked to adverse health effects such as birth defects, reproductive cancers, and behavioral and learning disorders. The widely known chemicals BPA and phthalates are only a few of thousands of chemicals suspected to have EA.

Under the agreement, PlastiPure will develop, test, and certify PlastiPure-Safe™ EA-Free products for ReliaBrand release in late 2010 and 2011. This broad suite of products should retain the key benefits that originally attracted consumers to these brands, with the additional benefit of improved safety from avoiding the chemicals with EA that leach from most plastics, silicones, colorants, and other materials.

“We are pleased to partner with the innovative companies under the ReliaBrand umbrella who share our mission of providing the highest-quality, safest plastic products.  The Adiri, ReliaDose, and WaterGeeks brands encompass several industries concerned about the safety of plastics, which will greatly benefit from using our PlastiPure-Safe™ EA-Free technology,” said PlastiPure CEO Mike Usey. “These and other ReliaBrand companies will be able to leverage PlastiPure’s long experience in addressing endocrine disruption caused by plastics that leach chemicals having EA.”

Increasing consumer concern over the safety of plastics has led to the introduction of BPA- and phthalate-free plastic products. However, these solutions are flawed because BPA and phthalates are only a few of thousands of estrogenic chemicals, many hundreds of which are used in plastics and many more which are unintentional side products of plastics manufacturing. These synthetic estrogenic chemicals can leach into food and beverages, and eventually into the environment.

In fact, tests of BPA-free products have indicated that the large majority released other chemicals having very high levels of EA. For example, PlastiPure’s testing of fifteen premium-brand BPA-free baby bottles found that all tested positive for EA, with eight leaching chemicals with EA measuring at or above the EA of BPA-containing polycarbonate.

PlastiPure technology can be easily implemented to make most materials and products free of leachable estrogenic chemicals. The partnership between PlastiPure and ReliaBrand is a key step to wider availability of EA-Free consumer products. “When consumers see the PlastiPure-Safe™ EA-Free certification seal on their products, they know the products are as safe as they can be,” Usey said.
