Studies of propyl and longer-chain (e.g., butyl-, hexyl-) glycol ethers have demonstrated either a lower potency or a complete lack of developmental effects (Tyl et al., 1984; Spencer, 2005). The reaction always results in a mixture of mono-, di-, and triglycol ethers, which are then distilled to the required purity. Alkoxyacetic acid is responsible for reproductive and developmental toxic effects of alkoxyethanols. Glycol ethers are metabolized to the corresponding aldehyde and alkoxyacetic acid by cytosolic alcohol dehydrogenase (ADH; EC 1.1.1.1) and aldehyde dehydrogenase (ALDH; 1.2.1.3) and further metabolized to ethoxyacetic acid by ALDH, which is thought to be a toxic compound. Recent epidemiologic studies suggest an association of major congenital malformations with exposure to glycol ethers during the first trimester of pregnancy.

Kimber I, Pieters R. (2013) Household chemicals, immune function, and allergy: A commentary. endstream endobj startxref In a British study, glycol ether exposure was, however, related to low motile sperm count (Cherry et al., 2008). This included explorations of the structure–activity relationships, and many studies using the two most potent congeners (ethylene glycol monomethyl ether [EGME] and ethylene glycol monoethyl ether [EGEE]) as tool compounds to visualize various patterns of response. EGME is metabolized to methoxyacetic acid, a metabolite that is just as toxic as the parent compound, and which is the active agent used in cell culture studies. Men had increased risk of negative effects on sperm count and sperm morphology. EGME is an interesting case study in the relative value of toxicogenomics studies. Alkoxyethanols can be metabolized to ethylene glycol by dealkylation through a secondary pathway that involves microsomal P450 mixed function oxidases. The glycol ethers were also used as investigative toxicants in the emerging field of male reproductive toxicology in the early 1980s.

Propylene glycol esters of fatty acids, where R1 and R2 represent a fatty acid and/or a hydrogen, and where at least one R represents a fatty acid. [Ford, p. 776] The three categories of glycol ethers in this database are Glycol Ethers (E Series), Glycol Ethers (P Series), and Glycol Ethers (Glymes). Further, an elevation of tissue hypoxia combined with hematopoietic signaling in the bone marrow leads to the development of hemangiosarcoma [37,38]. Proceedings of the Third International Scientific Symposium on the Health Effects of Glycol Ethers – 2002. Work in the 1980s and 1990s regarding various mechanisms had explored several separate avenues: (1) that MAA could form an MAA–CoA metabolite which could disturb carbohydrate metabolism; (2) that calcium channel blockers and kinase inhibitors could prevent many of the testicular (and other) toxicities observed after EGME treatment; (3) that Sertoli cells were required for the full expression of the cell death program in the spermatocytes; and (4) that kinase activity plays a central role in the spermatocyte death. The preceding section described the clinical features of ethylene glycol poisoning in three stages that are based on the time after ingestion. h�b```f``��������A��2,@����0����i��P�]�U��l�vT�&�%�A$��9����D0 +��p�Hs1Xd?c����6�V̑�p��� ���QH � �N�Ҍ@��p�00ܒ��2F i��3'!�x��4�4�g`x����>@� �%T In laboratory animals, low-level exposure to certain glycol ethers can cause birth … Eight years of research on widely marketed solvents assessed at industry-sponsored conference The glycols (alkyl diols) and glycol ethers are widely used industrial chemicals.

Nadri, in Encyclopedia of Toxicology (Third Edition), 2014. This elasticity provides clinical advantages because it allows substantial swelling without cutting into tissue and maintains tissue approximation throughout healing. Glycol ethers (Ge) are a family of substances with a growing use in industrial and domestic products for the two last decades. Starek, A., Szymczak, W. and Zapór, L. (2008) Hematological effects of four ethylene glycol monoalkyl ethers in short-term repeated exposure in rats. By continuing you agree to the use of cookies. The data in these assessments will be used to inform the health effects characterization for the Ethylene Glycol Ethers Group. Fatty acid polyglycol esters are good o/w emulsifiers. MENU. Extensive tables present information on the synonyms of the various compounds concerned, on their physical properties and on a large number of animal tests performed. Reports from 200 individuals from 17 countries illustrated the worldwide interest in glycol-ether toxicity. Glycol Ethers Causes reproductive effects . For example, propylene glycol ethyl ether (PGEE) and its acetate do not cause the critical toxicities of testicular, thymic, or blood injury and do not produce birth defects. Health Hazard Information Acute Effects: Acute exposure to high levels of the glycol ethers in humans results in narcosis, pulmonary edema, and severe liver and kidney damage. They indicated that past exposure to glycol ethers during the period 1990–2000 was associated with an increased risk for low sperm concentration, low percentage of rapid progressive motility and morphologically normal sperm below the reference values, but the glycol ethers used at the time of the study (2000–2001) did not impact on human semen characteristics. Dart, in Comprehensive Biomaterials II, 2017. Cohen, R. (1984) Reversible subacute ethylene glycol monomethyl ether toxicity associated with microfilm production, a … T. Kinyanjui, ... S. Mahungu, in Encyclopedia of Food Sciences and Nutrition (Second Edition), 2003. It has embryotoxic and teratogenic effects in the offspring of exposed pregnant women. It has a high degree of elastic stretch under low loads offering distinct advantages over other non-absorbable sutures (Rodheaver et al., 1986). Subsequent work on this and another short-chain fatty acid (valproic acid) found early and specific dysregulation of multiple nuclear receptors through activating the mitogen-activated protein kinase (MAPK) and inhibiting histone deacetylase, although neither were sufficient to account for all the receptor-potentiating effects reported for MAA. Depending on the chemical structure and the size of the molecule, these compounds may be able to damage the unborn child and are suspected of damaging fertility. Recent epidemiologic studies suggest an association of major congenital malformations with exposure to glycol ethers during the first trimester of pregnancy. Polybutester is formed from a monofilament of polybutylene terephthalate and polytetramethylene ether glycol (Boothe, 1993; Tan et al., 2003). In a study of topical exposure of mice to 2-BE, Singh et al. The other thing this calls into question is the current common practice of linking gene response data from affected cells to the lesions in those cells. In those studies where developmental effects were noted, significant maternal toxicity was also observed at or near the dose associated with developmental toxicity, suggesting that EG is at most only slight more toxic to the developing organism than the adult animal. Glycol ethers are colorless and flammable polar liquids that can be readily miscible with alcohol, liquid esters, ether, acetone, and water. The association appeared particularly strong in neural tube defects, multiple anomalies and cleft lip. endstream endobj 238 0 obj <>/Metadata 21 0 R/Names 254 0 R/Outlines 282 0 R/PageMode/UseOutlines/Pages 219 0 R/SpiderInfo 231 0 R/StructTreeRoot 43 0 R/Type/Catalog/ViewerPreferences<>>> endobj 239 0 obj <>/Font<>/ProcSet[/PDF/Text/ImageC/ImageI]/XObject<>>>/Rotate 0/StructParents 6/Tabs/S/Type/Page>> endobj 240 0 obj <>stream It is able to stretch to 50% of its original length at a load of 25% of its known breaking point (Rodheaver et al., 1986; Moy et al., 1992).

Methoxyethanol is an E-series glycol ether derived from methanol and ethylene oxide. Dianne M. Creasy, Robert E. Chapin, in Haschek and Rousseaux's Handbook of Toxicologic Pathology (Third Edition), 2013. Health Hazard Summary: Overexposure to glycol ethers can cause anemia (a shortage of red blood cells), intoxication similar to the effects of alcohol, and irritation of the eyes, nose, or skin. (2005) Toxicology letters, 153(1): 1-226. Volume 156, Issue 1, Pages 1-226 (28 March 2005) Download full issue. Many compounds in this group have properties that may cause severe health effects. 57, pp. A robust toxicity database exists for the propylene glycol ethers that provide strong product safety support. Cellosolve was a solvent product containing glycol ethers and registered in the 1920s by Carbide and Carbon Chemicals Corp. Glycol ethers are derived from either ethylene oxide (E-series) or propylene oxide (p-series) combined with an alcohol. Wang, in Encyclopedia of Toxicology (Third Edition), 2014. Propylene glycol ethers are a class of solvents used in a wide array of industrial, commercial and consumer applications, such as in paints, cleaners and inks. In 1981, NIOSH began investigating the potential reproductive health effects resulting from exposures to a class of organic solvents known generically as glycol ethers (GE). In order to increase their volatility, the free hydroxyl group of the ether can be esterified, usually with acetic acid. 1 A new study in Environmental Health Perspectives provides some of the first evidence of associations between prenatal exposures to glycol ethers and cognitive impairments in children. Copyright © 2021 Elsevier B.V. or its licensors or contributors. The Glycol Ethers, with Particular Reference to 2-Methoxyethanol and 2-Ethoxyethanol: Evidence of Adverse Reproductive Effects The National Institute for Occupational Safety and Health (NIOSH) recommends that 2-methoxyethanol (2ME) and 2-ethoxyethanol (2EE) be regarded in the workplace as having the potential to cause adverse reproductive effects in male and female workers. Fatty acids can be esterified directly to polyethylene glycol ethers or by enzymatic preparation, which allows better control of the reaction. Proceedings of the Third Internation Scientific Symposium on the Health Effects of Glycol Ethers - 2002 (3rd ISSHEGE) 17-18 October 2002 • Paris, France. Health effects of glycol ethers reviewed. That begins to be found in humans. This research was begun as a result of the NIOSH criteria document development program which revealed little data available on the health effects of glycol ether exposure. They are absorbed as volatile fumes from the air by the skin as well as inhalation. Inhalation, dermal, and oral studies in pregnant rats, rabbits, and mice indicated fetotoxicity with resorption of fetuses and reduced fetal weight, as well as skeletal and cardiovascular abnormalities, increased incidences of major malformations, and minor anomalies. Environmental Health Perspectives Vol. Studies of exposed male workers show that glycol ethers can reduce sperm counts and pregnant women exposed to glycol ethers in their work environments are significantly more likely to have children with birth defects such as neural tube defects and cleft lip.157,158, Helena Taskinen, ... Markku Sallmén, in Reproductive and Developmental Toxicology, 2011. It is encouraging to think that multiple cell types would give the same response, but daunting to consider how much more we have to learn in order to predict a real in vivo response. G.S. Tyler and J. Kelsey. Similar findings were reported in a rodent teratology study involving diethylene glycol and triethylene glycol but studies of propylene glycol have not observed any developmental effects at doses ranging from 1000 to 10 000 mg kg−1 day−1 (Driscoll et al., 1993; Enright et al., 2010). Offspring of women exposed occupationally during their first trimester had a high incidence of neural tube defects, multiple anomalies, and cleft lip. Numerous pathogenesis studies identified the early and late pachytene spermatocytes (but not mid pachytene spermatocytes) and the dividing spermatocyte as the most sensitive germ cell for this family of toxicants, with cell death being stage-specific and occurring within 12 hours of a single dose. Glycol ethers may be used in any food-related application (such as coatings or printing inks) without regard to specific FDA regulations if subsequent processing steps, such as washing, drying, vaporizing, heating, purging, etc., are adequate to completely remove all traces of the solvent. Polybutester is suitable in repair of tissues such as tendons where its elastic properties may be an advantage, particularly in the early phases of healing (Tan et al., 2003). In a multicenter case–control study, maternal glycol ether exposure was associated with congenital malformations (Cordier et al., 1997). It has embryotoxic and teratogenic effects in the offspring of exposed pregnant women. Numerous follow-on studies have used this compound as a tool, based on that observation and on the assumption of the spermatocyte being the specific target. Use of methoxyethanol has declined in recent years due to risk management procedures and replacement by other substances. For example, diethylene glycol dimethylether exposure in pregnant mice produced reduction in fetal body weights and skeletal malformations at 125 mg kg−1 day−1, a dose that did not have systemic effects in the maternal animals (Price et al., 1987). The biological effects of glycol ethers were reviewed in the proceedings of a 1996 meeting. Maureen Paul, Sabrina Kurtz, Analysis of reproductive health hazard information on material safety data sheets for lead and the ethylene glycol ethers, American Journal of Industrial Medicine, 10.1002/ajim.4700250308, 25, 3, (403-415), (2007). Ethoxyacetic acid can be further metabolized to carbon dioxide by O-deethylation or glycine conjugated analogs. Oral and inhalation exposure studies in male rabbits, mice, and rats resulted in testicular atrophy and altered sperm count. Archives of Toxicology, 82(2), 125-136. An update on toxicity studies of glycol ethers to Apr. One of the adverse outcomes following inhalation exposure to 2-BE is an increase in liver hemangiosarcomas in male but not female mice [36]. Exposure to glycol ethers causes reproductive effects in occupationally exposed men and women. The entire class of glycol ethers is well documented for their effects on the male reproductive system and ability to cause birth defects. Due to the formation of highly explosive peroxides in the air (not in the solution), they should be protected from heat and other ignition sources. Previous article in issue: Effects of exposure to ethylene glycol ethers on shipyard painters: II. Previous vol/issue. This screening assessment includes consideration of information on chemical properties, environmental fate, hazards, uses and exposure, including additional information submitted by … Jane Lyttleton BSc (Hons) (NZ) MPhil (UK) Dip TCM (Aus) Cert Acup (China) Cert Herbal Med (China), in Treatment of Infertility with Chinese Medicine (Second Edition), 2013, Glycol ethers are a large group of organic solvents used in industry and the home as glass cleaners, carpet cleaners, floor cleaners and oven cleaners. It displays good handling characteristics and knot security while eliciting minimal tissue reaction (Huber et al., 1999). Being a monofilament it is less likely to harbor bacteria. (1) The Leydig cells never appeared abnormal, although prostate weights were occasionally reduced in some studies. Ethylene Glycol Ethers Group - information sheet - Canada.ca The use of the most toxic glycol ethers has decreased from the mid-1990s and has gradually been replaced with less toxic long chain glycol ethers and propylene glycol ethers. / Institut National de Recherche et de Securite / National Institute for Occupational Safety and Health / Sweden; National Institute of Occupational Health | 1996 On the other hand, for these to be changed in an unaffected cell type calls into question our ability to predict what the response would be in an animal (human or rodent) after such an exposure. Although confusing, a possible way to view these data is that they may imply a future where pathway testing is done in any available cell type (or perhaps multiple cell types), and then a yet-to-be-discovered method is applied to identify which cell types will be the ones responding. 252 0 obj <>/Filter/FlateDecode/ID[<450DC4F8A4C42841A0305B32EECF0183>]/Index[237 218]/Info 236 0 R/Length 98/Prev 60580/Root 238 0 R/Size 455/Type/XRef/W[1 2 1]>>stream In 1981, NIOSH began investigating the potential reproductive health effects resulting from exposures to a class of organic solvents known generically as glycol ethers (GE). A.J. Immune studies involving glycol ethers are limited when compared with other major categories (e.g., heavy metals and dioxins) of EDCs. Propylene glycol fatty acid (C12, C14, C16, C18, and C18:1) monoesters (Figure 6) have been produced by lipase-catalyzed reactions. Animal studies have reported testicular damage, reduced fertility, early embryonic death, birth defects, and delayed development from inhalation and oral exposure to the glycol ethers.156 Occupational exposure to glycol ethers has also been shown to result in reproductive and developmental impacts in humans. How would we be able to predict that spermatocytes would be the responding cell based on these data from a Leydig cell line? Glycol ethers and their acetates are used in a variety of industries and products. h��[�n�r����/�*�0 ���|?��1$QI&)k��Zp���I�=3W��{��� ���'����bu�-����,.�����GDfĉ�̢�S���*!���i茼��E�4uѰ^�rȝ ���8dt�]B�`:,I��1�}@���t����jER�Rd�! Glycol ethers are a large group of organic solvents used in industry and the home as glass cleaners, carpet cleaners, floor cleaners and oven cleaners. A current model of 2-BE effects seen in mice suggests that 2-BE induces macrophage activation and inflammation in the liver involving Kupffer cells (liver macrophages). In 1981, NIOSH began investigating the potential reproductive health effects resulting from exposures to a class of organic solvents known generically as glycol ethers (GE). They are extensively used as solvents in industrial processes and manufacturing and as thinner and viscosity improving agents in coating processes. The main pathway of ethylene glycol ethers is associated with significant clinical or experimental health effects and the minor pathway is also interesting because formation of urinary stones depends principally upon the urinary concentration of oxalate and calcium. 454 0 obj <>stream The initial materials for the preparation of glycol ethers are ethane oxide (giving ethylene glycol ethers), propane oxide (giving propylene glycol ethers), and alcohols of the desired carbon chain length. Authors; Librarians; Editors; Societies Investigators could differentiate gene responses into different classes based on how MAA interacted with applied testosterone. Methoxyethanol is a glycol ether that has been known since the 1920s, but its use significantly increased in the 1970s. Dart, C.M. Alkoxyethanols are mainly eliminated as alkoxyacetic acid via urine. Glycol ethers do not generally have properties that pose a risk for the environment. Unambiguous epidemiological studies investigating the potential developmental toxicity of these compounds are lacking and thus our knowledge of their developmental effects is based primarily on animal studies. Several epidemiology studies have been conducted after occupational exposure that indicates impaired reproductive capability in men and women. 273-275, 1984 Summaryand Overview: NIOSH Symposium onToxic Effects of Glycol Ethers by Bryan D.
