Learn about phthalates and if they're safe. In Europe the current figures is 72 %. SP Swedish National Testing and Research Institute and the International Centre for Indoor Environment and Energy, Technical University of Denmark Karlstad University, Sweden. However, Dioctyl terephthalate (a terephthalate isomeric with DEHP) and 1,2-Cyclohexane dicarboxylic acid diisononyl ester (a hydrogenated version of DINP) are available at cost-competitive pricing and with good plasticization properties. [5] This transition to phthalate-free plasticizers has prevented manufacturers from using post-consumer recycled plastic as that recycled content would likely contain phthalates. A 2011 study of residents in Albany, NY calculated that house dust could contribute 10-58% of total DEHP exposure. Building materials such as vinyl flooring and other consumer products containing phthalates can result in human exposure through direct contact and use, indirectly through leaching into other products, or general environmental contamination. Women are exposed to higher levels of phthalates than men, and children are more greatly exposed to phthalates than adults. The alkyl chains of the phthalate then screen the PVC chains from each other as well. Several studies have shown associations between phthalate exposures and human health, although no causal link has been established. Some regulations include: Several authoritative evaluations have examined alternatives to phthalates in a variety of flexible vinyl products,[xv] including vinyl flooring,[xvi] wall coverings,[xvii] medical devices,[xviii] and wire and cable. 2006. http://www.cdc.gov/exposurereport/pdf/fourthreport_updatedtables_aug2014.pdf, http://www.nap.edu/catalog.php?record_id=12528, http://www.sustainableproduction.org/downloads/PhthalateAlternatives-January2011.pdf, http://healthybuilding.net/uploads/files/phthalate-free-plasticizers-in-pvc.pdf, http://www.turi.org/TURI_Publications/TURI_Methods_Policy_Reports/Five_Chemicals_Alternatives_Assessment_Study._2006, http://www.sustainableproduction.org/downloads/DEHP%20Full%20Text.pdf, http://www.greenchemistryandcommerce.org/assets/media/images/Publications/Pilot%20Project%20Full%20Report%20Oct%202%20-%20final.pdf, http://www.epa.gov/dfe/pubs/projects/phthalates/index.html. Too many beauty or self-care products contain phthalates that go directly... 3. Generally the high molecular weight phthalates DINP, DIDP and DPHP have been registered under REACH and have demonstrated their safety for use in current applications. Plasticizers contribute 10-60% of total weight of plasticized products. A study published in 2013 found vinyl flooring linked to asthma in children. House dust can be inhaled or ingested. Because of these additive effects, NAS strongly recommended the use of cumulative risk assessment that considers the effects of all phthalates (and other anti-androgens) together. Some of the common phthalates found in consumer products include: Many phthalates are hormone-disrupting chemicals that interfere with the production of the male sex hormone, testosterone, which is necessary for proper development and function of the male reproductive organs. Health Effects of Phthalates. [19] Another study, conducted between 2003 and 2010 analysing data from 9,000 individuals, found that those who reported that they had eaten at a fast food restaurant had much higher levels of two separate phthalates—DEHP and DiNP—in their urine samples. [i] The CHAP applied conventional assumptions from regulatory toxicology to suggest “safe” levels of exposure to each phthalate. Four phthalates are scheduled for a complete phase-out in Europe under REACH, the European Union’s comprehensive chemical policy, in 2015, except for any uses that are temporarily exempted (i.e. The presence of PVC flooring in the child’s bedroom was the strongest predictor of respiratory ailments. [31] Finally, particularly low levels of exposure may still have significant effects, and exposure to multiple endocrine disruptors across a variety of compounds (not just phthalates) may synergistically combine to cause a greater effect. [viii] Jaakkola, J.J.K., Ieromnimon, A. and M.S. (DBH-STEP 1). [57], In February 2009, the Joint Research Centre (JRC) of the European Commission published a review of methods to measure phthalates in food. The report stated: “Some phthalates- such as DBP, BBP, DEHP and DINP- are able to disrupt male sexual differentiation by interfering with androgen biosynthesis;” (p.106). "[44] Phthalates belong to this class of metabolic disruptors. An endocrine disruptor is a substance that interferes with the normal hormonal mechanisms that allow a biological organism to interact with its environment. [26] Thus, the effect of phthalates should be examined together with other antiandrogens, which otherwise may have been excluded because their mechanisms or structure are different. Phthalates are used in some but not all PVC formulations, and there are no specific labeling requirements for phthalates. ", "Sperm counts are falling. ‘Comparative assessment of human exposure to phthalate esters from house dust in China and the United States’. In summary, infants’ and children’s physiology, developmental stages, and age-appropriate behaviors all may increase exposure to phthalates. For example, they can be removed by heating or by extraction with organic solvents. For this to be established, the polymer must be heated in the presence of the plasticizer, first above the Tg of the polymer and then into a melt state. A study of adults working in rooms with plastic wall covering materials were more than twice as likely to develop asthma. Healthy Stuff A more recent cumulative risk assessment by the Chronic Hazard Advisory Panel (CHAP) of the Consumer Product Safety Commission concluded that 10% of pregnant women and 5% of infants are exposed to unsafe levels of phthalates in U.S. [i]  Based on available data, which are incomplete, the CHAP experts concluded that cumulative exposure to five phthalates creates an unacceptable risk of male reproductive toxicity among those pregnant women and babies exposed to the highest levels of phthalates. (Several of these listed phthalates are actually commercial mixtures, each of which contains multiple phthalate compounds). Phthalates are a group of chemicals used in plastics to soften and increase flexibility. [45] The carcinogen classification was subsequently withdrawn. Break your addiction to flexible plastic food wrap in favor of non-toxic plastic wrap alternatives. The phthalates have a clear syrupy liquid consistency and show low water solubility, high oil solubility, and low volatility. Asthma symptoms in relation to measured building dampness in upper concrete floor construction, and 2-ethyl-1-hexanol in indoor air. Phthalate plasticizers are not chemically bound to vinyl, they can leach, migrate or evaporate into indoor air and concentrate in household dust. This enables an intimate mix of polymer and plasticizer to be formed, and for these interactions to occur. Phthalates (US: /ˈθæleɪts/,[1] UK: /ˈθɑːleɪts/[2]), or phthalate esters, are esters of phthalic anhydride. Fatty foods such as milk, butter, and meats are a major source. [xiii] A 2014 study using biomonitoring data and modeling estimated that 39% of DEHP levels were attributable to indoor dust ingestion and 14% to inhalation.[xiv]. The author of the study stated "The roles of PPARs in lipid and carbohydrate metabolism raise the question of their activation by a sub-class of pollutants, tentatively named metabolic disrupters. In another development in 1986, California voters approved an initiative to address their growing concerns about exposure to toxic chemicals. ‘Attributing population-scale human exposure to various source categories: merging exposure models and biomonitoring data’. 5 Ways to Avoid Phthalate Exposure 1. Regulatory pressure – including bans and reporting – continues to mount against phthalates based on the growing body of credible scientific evidence. The Food and Drug Administration did an extensive risk assessment of phthalates in the medical setting and found that neonates may be exposed to five times greater than the allowed daily tolerable intake. Dampness at home as a risk factor for symptoms among 10,851 Swedish children. For example, most Americans tested by the Centers for Disease Control and Prevention have metabolites of multiple phthalates in their urine. According to a report published by the US National Academy of Sciences, “Indoor air is another source of exposure to phthalates from a variety of sources, including aerosols generated from polyvinyl chloride household products, such as vinyl flooring…Infants and young children have higher specific respiratory rates than adults (Etzel and Balk 2003; EPA 2006) and thus have potentially higher specific exposures via inhalation. PVC-flooring at home and development of asthma among young children in Sweden, a 10-year follow-up. In general, they do not persist due to rapid biodegradation, photodegradation, and anaerobic degradation. Data on flooring materials was collected, but there was not a significant difference in concentrations between homes where no polish was used that have balatum (PVC or linoleum) flooring and homes with wood. [xix] Green Chemistry & Commerce Council, Chemical Hazard Assessments of Alternative Plasticizers for Wire & Cable Applications, June 2013. In 1870, camphor became the more favored plasticizer for cellulose nitrate. The Task Ahead. The timing of exposure is critical to the severity of effects. This isn't the reproductive apocalypse — yet", "Sperm Count in Western Men Has Dropped Over 50 Percent Since 1973, Paper Finds", "Exposure to phthalates: Reproductive outcome and children health. [xxi] Sarah Lott, Healthy Building Network, Phthalate-free Plasticizers in PVC, September 2014. [xiv] Shin, H, McKone, T, and Bennett, D, (2014). Although the report gave preference to two biobased alternatives cited above, all six alternatives profiled had a safer environmental health profile than the phthalate DINP. At least 41 phthalates are now under regulation by authoritative government agencies in North America and Europe. In 2008, Congress directed the Consumer Product Safety Commission to permanently ban in children’s toys the use of three phthalates (BBP, DBP and DEHP) and provisionally ban DiDP, DiNP, and DnOP pending further review by the CPSC. A study of 10,851 children found the presence of floor moisture and PVC significantly increased the risk of asthma. The fetus is the most sensitive life stage for male reproductive effects, and pubertal animals show effects at lower doses than those showing effects in adult animals.”. [57] One hypothesis is that these may have been introduced during plastics recycling. A recent Nature Reviews Endocrinology review paper[30] gives some advice for avoiding exposure to phthalates for concerned people; while they make pains to state that there is no evidence that shows this advice will positively affect one’s health, they suggest (1) eating a balanced diet to avoid ingesting too many endocrine disruptors from a single source, (2) eliminating canned or packaged food in order to limit ingestion of DEHP phthalates leached from plastics, and (3) eliminating use of any personal product such as moisturizer, perfume, cosmetics that contain phthalates.
