WechselwirkungenAgricultural workers are encouraged to use sunscreen to decrease the risk of UV-related skin cancer. Our previous studies have shown certain commercial sunscreens to be penetration enhancers. The focus of this project is to determine whether active ingredients in sunscreen formulations (i.e., the UV absorbing components and insect repellants for the sunscreen/bug repellant combinations) also act as dermal penetration enhancers for herbicides in vitro. The total percentages of 2,4-dichlorophenoxyacetic acid (2,4-D) penetrating through hairless mouse skin in 24 h ranged from 54.9 +/- 4.7 for the no sunscreen control to 86.9 +/- 2.5 for padimate-o. Of the active ingredients tested (7.5% octyl methoxycinnamate, 7% octocrylene, 0.6% oxybenzone, 5% homosalate, 5% octyl salicylate, 8% padimate-o, 10% sulisobenzone, and 9.5% and 19% N,N-diethyl-m-toluamide [DEET]), all but octocrylene led to a significant increase in total 2,4-D penetration as compared to the control (P < 0.05), and only octocrylene and oxybenzone did not significantly decrease the corresponding lag time. Octyl salicylate (P < 0.01) and octyl methoxycinnimate (P < 0.05) significantly increased the 3H2O penetration across mouse skin, indicating physical damage to the stratum corneum. Additional studies demonstrated that the penetration enhancement seen across hairless mouse skin also occurred with human skin. Thus, the active ingredients of sunscreen formulations enhance dermal penetration of the moderately lipophilic herbicide 2,4-D.Diminish the penetration of ultraviolet (UV) light through the epidermis by absorbing UV radiation within a specific wavelength range. The amount and wavelength of UV radiation absorbed are affected by the molecular structure of the sunscreen agent. /Sunscreen agents, topical/
UmweltverhaltenTERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 67(SRC), determined from a structure estimation method(2), indicates that sulisobenzone is expected to have high mobility in soil(SRC). The estimated pKa values of sulisobenzone are -2.4 and 7.6(3), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization from moist soil is not expected because the compound exists as an anion and anions do not volatilize. Sulisobenzone is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.3X10-11 mm Hg at 25 °C(SRC), determined from a fragment constant method(2). No relevant data were available to assess the importance of biodegradation in the environment(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 67(SRC), determined from a structure estimation method(2), indicates that sulisobenzone is not expected to adsorb to suspended solids and sediment(SRC). Estimated pKa values of -2.4 and 7.6(3) indicate sulisobenzone will exist almost entirely in the anion form at pH values of 5 to 9 and, therefore, volatilization from water surfaces is not expected to be an important fate process(SRC). According to a classification scheme(4), an estimated BCF of 3(SRC), from an estimated log Kow of 0.37(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Sulisobenzone is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(5). Sulisobenzone absorbs at wavelengths >290(6) nm and therefore may be susceptible to direct photolysis by sunlight(SRC). Phenols are susceptible to sensitized photolysis in natural waters exposed to sunlight through reaction with hydroxy and peroxy radicals(7)therefore sensitized photolysis may have some importance in the environment(SRC). No relevant data were available to assess the importance of biodegradation in the environment(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), sulisobenzone, which has an estimated vapor pressure of 1.3X10-11 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase sulisobenzone may be removed from the air by wet and dry deposition(SRC). Sulisobenzone absorbs at wavelengths >290 nm(3) and therefore may be susceptible to direct photolysis by sunlight(SRC).

Ökotoxizitätsauszüge/AQUATIC SPECIES/ In this work, /the authors/ evaluate whether in vitro systems are good predictors for in vivo estrogenic activity in fish. /Investigators/ focus on UV filters being used in sunscreens and in UV stabilization of materials. First, /investigators/ determined the estrogenic activity of 23 UV filters and one UV filter metabolite employing a recombinant yeast carrying the estrogen receptor of rainbow trout (rtERalpha) and made comparisons with yeast carrying the human hERalpha for receptor specificity. Benzophenone-1 (BP1), benzophenone-2 (BP2), 4,4-dihydroxybenzophenone, 4-hydroxybenzophenone, 2,4,4-trihydroxy-benzophenone, and phenylsalicylate showed full dose-response curves with maximal responses of 81-115%, whereas 3-benzylidene camphor (3BC), octylsalicylate, benzylsalicylate, benzophenone-3, and benzophenone-4 displayed lower maximal responses of 15-74%. Whereas the activity of 17beta-estradiol was lower in the rtERalpha than the hERalpha assay, the activities of UV filters were similar or relatively higher in rtERalpha, indicating different relative binding activities of both ER. Subsequently, /investigators/ analyzed whether the in vitro estrogenicity of eight UV filters is also displayed in vivo in fathead minnows by the induction potential of vitellogenin after 14 days of aqueous exposure. Of the three active compounds in vivo, 3BC induced vitellogenin at lower concentrations (435 ug/L) than BP1 (4919 ug/L) and BP2 (8783 ug/L). The study shows, for the first time, estrogenic activities of UV filters in fish both in vitro and in vivo. Thus /investigators/ propose that receptor-based assays should be used for in vitro screening prior to in vivo testing, leading to environmental risk assessments based on combined, complementary, and appropriate species-related assays for hormonal activity./AQUATIC SPECIES/ ... Here /the authors/ report on acute and chronic effects of UV-filters 3-(4-methylbenzylidene-camphor) (4MBC), 2-ethyl-hexyl-4-trimethoxycinnamate (EHMC), benzophenone-3 (BP3) and benzophenone-4 (BP4) on Daphnia magna. The acute toxicity increased with log Pow of the compound. The LC50 values (48 hr) of 4MBC, EHMC, BP3 and BP4 were 0.56, 0.29, 1.9 and 50 mg/L, respectively. A tentative preliminary environmental risk assessment (ERA) based on a limited set of data indicates that individual UV-filters should undergo further ecotoxicological analysis, as an environmental risk cannot be ruled out. Consequently new data on the environmental occurrence and the effects of UV-filters are needed for a more accurate ERA. When regarded as a mixture occurring in surface waters they may pose a risk for sensitive aquatic organisms./AQUATIC SPECIES/ ...In this study, /investigators/ evaluate the effects of benzophenone-4 (BP-4) in eleuthero-embryos and in the liver, testis and brain of adult male fish on the transcriptional level by focusing on target genes involved in hormonal pathways to provide a more complete toxicological profile of this important UV-absorber. Eleuthero-embryos and males of zebrafish were exposed up to 3 days after hatching and for 14 days, respectively, to BP-4 concentrations between 30 and 3000 ug/L. In eleuthero-embryos transcripts of vtg1, vtg3, esr1, esr2b, hsd17beta3, cyp19b cyp19a, hhex and pax8 were induced at 3000 ug/L BP-4, which points to a low estrogenic activity and interference with early thyroid development, respectively. In adult males BP-4 displayed multiple effects on gene expression in different tissues. In the liver vtg1, vtg3, esr1 and esr2b were down-regulated, while in the brain, vtg1, vtg3 and cyp19b transcripts were up-regulated. In conclusion, the transcription profile revealed that BP-4 interferes with the expression of genes involved in hormonal pathways and steroidogenesis. The effects of BP-4 differ in life stages and adult tissues and point to an estrogenic activity in eleuthero-embryos and adult brain, and an antiestrogenic activity in the liver. The results indicate that BP-4 interferes with the sex hormone system of fish, which is important for the risk assessment of this UV-absorber.
Soil Adsorption/MobilityUsing a structure estimation method based on molecular connectivity indices(1), the Koc of sulisobenzone can be estimated to be 67(SRC). According to a classification scheme(2), this estimated Koc value suggests that sulisobenzone is expected to have high mobility in soil. The estimated pKa values of sulisobenzone are -2.4 and 7.6(3), indicating that this compound will exist in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
Human Toxicity Excerpts/HUMAN EXPOSURE STUDIES/ ...To determine the frequency of irritant reactions to 19 organic sunscreen filters in current use. Ninety-four healthy volunteers were photopatch tested using the European consensus methodology to three different concentrations (2%, 5%, and 10%) of 19 organic sunscreen filters at the Photobiology Unit in Dundee, UK. Of the 94 subjects recruited, 80 were analyzed after withdrawals and exclusions. Of the 19 organic sunscreen filters studied, only 2 compounds led to irritant reactions in > or =5% subjects. Five per cent and 10% benzophenone-4 led to irritant reactions in four and six subjects, respectively. Five per cent methylene bis-benzotriazolyl tetramethylbutylphenol led to irritant reactions in six subjects, but unlike benzophenone-4, this was not in a dose-dependent fashion. When performing photopatch testing according to the European consensus methodology with these 19 organic sunscreen filters, a 10% concentration is suitable for all filters, except benzophenone-4, which should be tested at a concentration of 2%./HUMAN EXPOSURE STUDIES/ Cosmetic products containing Benzophenones-2, -3, or -4 (0.l%-3.5%) were tested for phototoxicity in humans. In each study, the test material was applied under occlusion to the subject's skin for 24 hours. Sites were then scored, exposed to UV radiation, and then scored daily for up to seven days. Nonirradiated/treated and nontreated/irradiated controls were frequently used. Products containing Benzophenones-2, -3, and -4 were nonphototoxic in all studieshowever, a number of subjects experienced slight irritation (usually a 1+ response) to the test material./HUMAN EXPOSURE STUDIES/ /Investigators/ tested the potential irritancy of Benzophenone-4 on six adult white humans. Patches containing 1% or 10% Benzophenone-4 in alcohol were applied to the subjects for 24 hours, after which time the patches were removed, the sites scored, and fresh patches applied. This procedure was repeated every other day, three days per week for seven weeks, until a total of 21 patches had been made. The mean cumulative irritation scores for 1% and 10% solutions were 8.6 and 53.1, respectively (maximum score = 84). The latter value is indicative of a primary irritant./HUMAN EXPOSURE STUDIES/ Benzophenones-4 and -11 were tested for potential skin irritation in separate single insult patch tests. Each ingredient was applied at concentrations of 16, 8, and 4% in DMP /dimethyl phthalate/ and in petrolatum to the skin of each of 14 subjects. At a concentration of 16% in either base, Benzophenones-4 and -11 were irritating to four and two subjects, respectively. Neither ingredient was irritating at concentrations of 4% or 8% in either vehicle.For more Human Toxicity Excerpts (Complete) data for SULISOBENZONE (8 total), please visit the HSDB record page.
Artificial Pollution SourcesSulisobenzone's production and use as an ultraviolet absorber in cosmetics, sunscreens and shampoos and in leather and textile fabrics(1,2) may result in its release to the environment through various waste streams(SRC).
Environmental BioconcentrationAn estimated BCF of 3 was calculated for sulisobenzone(SRC), using an estimated log Kow of 0.37(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Volatilization from Water/SoilThe estimated pKa values of -2.4 and 7.6(1) indicate sulisobenzone will exist almost entirely in the anion form at pH values of 5 to 9 and, therefore, volatilization from water and moist soil surfaces is not expected to be an important fate process. Sulisobenzone is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.3X10-11 mm Hg(SRC), determined from a fragment constant method(2).
Non-Human Toxicity Excerpts/LABORATORY ANIMALS: Acute Exposure/ A number of studies have determined the potential irritancy of Benzophenones to the eyes of rabbits. The test material (0.1 mL or 0.1 g) was instilled into one eye of each rabbitthe other eye served as an untreated control. Eyes were examined and scored for irritation daily for a period of three to ten days. Some test procedures included washing of the treated eyes with water four seconds after instillation of the test material. Results of eye irritation tests revealed that most Benzophenones at concentrations of 5%-100% were nonirritating when instilled into the eyes of rabbits. Benzophenones-1, -2, and -4 were slightly to moderately irritating at 100% concentrationhowever, ... Benzophenone-4 was irritating at concentrations of 8 and 16% in DMP /dimethyl phthalate/ or petrolatum, it was nonirritating when tested as a 5% solution in water./LABORATORY ANIMALS: Acute Exposure/ An occlusive patch containing 0.5 mL or 0.5 mg of the test ingredient was applied to the intact and abraded skin of albino rabbits. Patches remained in place for 24 hours and were then removed and scored for irritation according to the Draize method. Sites were again scored 24 hours after patch removal. ... Benzophenones-1, -4, and -6 were minimally irritating (PII = 0.25-0.50) when applied as 16% solutions in dimethyl phthalate (DMP). However, these ingredients were nonirritating at 8% in DMP and at 16% in petrolatum./LABORATORY ANIMALS: Subchronic or Prechronic Exposure/ ...A 16-day cumulative test in rabbits /was used/ to study the irritation potential of Benzophenone-4. An alcohol solution containing either 10% or 1% Benzophenone-4 was applied uncovered to the depilated backs of six New Zealand albino rabbits. Twenty-four hours later the sites were scored for irritation, and the solution was reapplied. This procedure was repeated every other day for five weeks, until a total of 16 applications of Benzophenone-4 had been made. The average cumulative irritation score was then calculated (maximum score = 64)applications of Benzophenone-4 (10%) and Benzophenone-4(1%) produced scores of 3.6 and 0.3, respectively./GENOTOXICITY/ The Ames Salmonella/Mammalian-Microsomal Assay was used to test Benzophenones-1, -2, -3, -4, -6, -8, -9, and -11 for mutagenicity. Salmonella typhimurium strains TA98, TAl00, TA1535, TA1537, and TA1538 were usedall tests were performed in the presence and absence of Aroclor-induced rat liver microsomal S-9 cell fraction to observe the mutagenic effect of each compound following metabolic activation. Preliminary cytotoxicity studies determined the dose range of each compound to be used. All Benzophenones were nonmutagenic when assayed directly. All but three Benzophenones (-2, -6, and -8) were nonmutagenic with metabolic activation.
Populations at Special RiskBecause the absorptive characteristics of skin of children younger than 6 months of age may differ from those of adults and because the immaturity of metabolic and excretory pathways of these children may limit their ability to eliminate any percutaneously absorbed sunscreen agent, sunscreen products should be used in children younger than 6 months of age only as directed by a clinician. It is possible that the characteristics of geriatric skin also differ from those of skin in younger adults, but these characteristics and the need for special considerations regarding use of sunscreen preparations in this age group are poorly understood. /Sunscreens/
