Other Reactions from Gloves

Several other depigmenting chemicals have now been identified, including alkylphenol p-tertiary butylphenol (PTBP), pyrethroid insecticides, hexamethylenetetramine, mercurial, arsenics, and sulfhydryls. When present in excess in Neoprene rubber glue containing p-tertiary butylphenol formaldehyde resins, PTBP has been associated with depigmentation in industrial workers and consumers when present in wristwatch adhesive and plastic shoes.1,19 To our knowledge, PTBP has not been found in gloves.

S. brasiliensis leaves contain tannins and polyphenols, such as methyl gallate, gallic acid, and ellagic acid. It contains alkylphenol methyl 6-eicosanoyl-2-hydroxy-4-methoxybenzoate isolates and 5α, 8α-epidioxy ergosta-6,22-dien-3β-ol. In the essential oil, a good amount of mircene and low amounts of other compounds such as β-caryophyllene, eucalyptol and guaiol are present (Fernandes et al. 2015). The major substances include hydrolysable tannins and flavonoids (Dos Reis Luz et al. 2018).

Hormone disruptors, such as anabolic steroids, polychlorinated biphenyls, dioxins, polycyclic aromatic hydrocarbons, phthalates, bisphenol A, pesticides, and alkylphenols have been studied for their impact on male fertility in several species of animals and in humans. Growing evidence suggests that xenoestrogen bisphenol A (BPA) (a widespread environmental contaminant, employed in the production of certain plastics and epoxy resins) can bind to receptors on sperm and, thus, alter sperm function. It has been reported that high concentrations of BPA alter sperm function, fertilization, and embryonic development via regulation and/or phosphorylation of fertility-related proteins in sperm collected from experimental mice.75
“The influence of female body mass index, menstrual cycle phase and age on propofol injection pain”

All phenols irritate skin and mucous membrane. Thus, propofol being an alkylphenol is expected to cause pain [1]. Propofol injection pain (PIP) and its severity may differ among patient populations with an incidence of 28%–90% in adult patients, in the absence of other pretreatments [1]. PIP usually is percepted as tingling, cold, or numbing or, at its worst, a severe burning pain. Despite this discomfort, the incidence of venous sequel, such as phlebitis, is less than 1% [2] PIP may be immediate or delayed after 10–20 seconds. The immediate pain is due to irritation of vein endothelium by free propofol present in the aqueous phase [3], whereas delayed pain is due plasma kallikrein-kinin system activation after propofol contacting with free nerve endings of vessels, thus locally liberating pain mediators [4].

EDC have been shown to have a widespread distribution in the natural environment and negative effects on living organisms (Colborn et al. 1996). Chemicals that alter the endocrine system may mimic, block, or change the activities of chemicals synthesized by the system itself. They particularly affect the thyroid gland, urinary system, and many other organs (Metzler and Pfeiffer 2001). Alkylphenols, a type of nonionic surface-active molecule, are the most important chemicals that impair the endocrine system. The break-up products of alkylphenols are nonylphenol and octylphenol with a wide range of use. These molecules have been demonstrated to reach dangerous environmental concentrations in recent studies (Colborn et al. 1996, Kelce and Wilson 2001, Metzler and Pfeiffer 2001). In a study conducted on wastewaters in the United States, the NP to OP proportion was 2–6 µg/L. The total APE level was within the 1350 to 11.00 µg/L range (Ruthann et al. 1998). Likewise, in Portugal, the APE levels in winter, spring, summer, and autumn were found to be 1968 ng/L, 605 ng/L, 522 ng/L, and 1105 ng/L in the Mira River, respectively (Rocha et al. 2016).
A review of the evidence for endocrine disrupting effects of current-use chemicals on wildlife populations
Published in Critical Reviews in Toxicology, 2018
Peter Matthiessen, James R. Wheeler, Lennart Weltje
Kortenkamp et al. (2012) also concluded that some wildlife populations had been harmed by ED, and they provide a list of so-called chemicals of concern, some of which are not POPs as listed by the Stockholm Convention, but which have been the subject of other regulatory action [e.g. tri-organotins; alkylphenols (APs)]. None of these substances were restricted specifically because they present an unacceptable risk from ED properties, as such, but simply because their fate and adverse effects (which may or may not have been caused by an endocrine mechanism) in the environment were deemed unacceptable. All can be described as legacy chemicals, which have been subject to regulatory action resulting in withdrawals from use or sale, but in some cases they are still widespread in the environment due to their persistence (e.g. Rasmussen et al. 2015), and may cause harm in some sensitive species.
