### Values in bold marked <WS indicates that the ECOSAR model calculated value is less than the water solubility

of P1400. **INTRODUCTION** The physical properties, environmental fate and distribution characteristics, and ecotoxicity

of Ferro product Santicizer P1400 (S - P1400, benzyl butylcyclohexane - 1,2 - dicarboxyl ate, CAS RN 1200806 - 67 - 2) are not known. These types of data are needed to conduct an environmental assessment. In order to support the design of the studies needed for an environmental assessment, structure - activity models can be used to estimate many

key properties. A suite of environmental properties models has been developed and assembled by the US Environmental Protection Agency (USEPA, EPI Suite v4.10). These models calculate basic physical properties such as melting point, boiling point, vapor pressure, and water solubility and partitioning properties such as Henry ’s Law constant, octanol -w ater partition coefficient, and sorption to soil/sediment. The suite of models also includes the estimation of hydrol ys is (for certain chemical groups only), atmospheric photo - oxidation, biodegradation, and bioaccumulation. These data are used to estimate the environmental distribution in a simulated environment. Fate in a wastewater treatment plant can be simulated. Acute and chronic toxicity values to aquatic organisms and earthworms can be

calculated. Many of the property and fate characteristics are cal culated using the structural features of the models, while others may rely on other properties such as octanol -water partition coefficient. In addition, EPI Suite v4.10 has a database of physical properties that were obtained from scientific literature, standard references, and other sources. The purpose of this report is to summarize the results that have been generated from EPI Suite v4.10 modeling using the molecular structure of the Ferro product P1400. The molecular formula, molecular structure and SMILES notation that are used to estimate the various properties using the structure - based models are shown in the attached EPISuite v4.10 output file. The formal name of the molecule is benzyl butyl cyclohexane - 1,2 - dicarboxylate, but will be referred to by its trade name (S - P1400) throughout this document. **PHYSICAL PROPERTIES** The key physical properties that are estimated using EPISuite v4.10 are melting point, boiling point, vapor pressure, and water solubility . The results are shown in Table 1 and in the attached modeling output file. Melting Point (MP) Using the submodel MPBPVP v1.43, melting points were calculated using two methods. Melting points of 14.95  C and 105.14  C were calculated using the Adapted Joback Method and the Gold and Ogle Method, respectively . The submodel selected the weighted value, based on the two calculate values, of 29.98  C as the representative melting point for S - P1400. However, the material is known to be liquid at ambient temperatures, so it appears that the model s omewhat overestimates the melting point. Boiling Point (BP) Using the submodel MPBPVP v1.43, a boiling point was calculated using the Adapted Stein and Brown Method. The calculated value of 374.72  C is selected as the representative boiling point for S - P1400. Vapor Pressure (VP) Using the submodel MPBPVP v1.43 vapor pressure was calculated at 25  C by three methods. Each method used melting and boiling points of 29.98 and 374.72  C to calculate vapor pressure. Vapor pressures of 1.34 E - 3 Pa (1.0 E - 5 mm Hg), 4.08 E - 3 Pa (3.06 E - 5 mm Hg), and 8.17 E - 3 Pa (6.13 E - 5 mm Hg) were calculated using the Antoine method, the Modified Grain Method, and the Mackay Method, respectivel y. The submodel selected 4.08 E - 3 Pa (3.06 E - 5 mm Hg) that was calculated using the Modified Grain Method as the representative vapor pressure for S - P1400.

Water Solubility

(WS) Water solubility

can be estimated using two submodels within EPI Suite v4.10. The first submodel (WSKOW v1.42) relies on the octanol - water partition coefficient that is introduced below and the compound’s molecular weight to estimate water solubility . Using this submodel, an estimated Log Kow value of 5.29, and a molecular weight of 318.42 g/mol, a water solubility of 0.29 mg/L is calculated. The second submode l (WATERNT v1.01) calculates a water solubility based on structural features of the molecule. Using this submodel, a water solubility of 0.68 mg/L is calculated. The results from the two submodels agree well. The model selected a water solubility for S - P14 00 of 0.29 mg/L. **PARTITIONING PROPERTIES** The key partitioning properties that are estimated using EPI Suite v4.10 are octanol -water partition coefficient, Henry ’s Law Constant, and soil/sediment partition coefficient. The results are shown in Table 1 and in the attached modeling output file. Octanol - Water Partition Coefficient (Log Kow) Octanol - water partition coefficients are calculated using the submodel KOWWI N v1.68 that calculates Log Kow values based on structural features of the molecule. For S P1400, a Log Kow value of 5.29 is calculated. Henry ’s Law Constant (Hc) Henry ’s Law Constants are calculated using three methods. Two methods rely on structural features of the molecule. The third method calculates an Hc value from the ratio of the va

por pressure and water solubility in molar units. Hc values of 1.45 E - 2 Pam3/mol (1.43 E - 7 atm m3/mol and 2.48 E - 4 Pa m3/mol (2.45 E - 9 atm m3/mol) were calculated using Bond Estimation and Group Estimation methods, respectively . Using the vapor pressure o f 4.08 E - 3 Pa (3.06 E - 5 mm Hg) and water solubility of 0.29 mg/L, an Hc value of 4.48 Pa m3/mol (4.42 E - 5 atm m3/mol) was calculated for S - P1400. Soil/Sediment Partition Coefficient (Koc) Soil/sediment partition coefficients are calculated using the submodel KOCWIN v 2.00. The submodel calculated Koc values using structural features of the molecule. A Koc value of 7155 L/kg was estimated for S - P1400. **ENVIRONMENTAL FATE** The key environmental fate characteristics that are estimated using EPISuite v4.1 0 include both abiotic and biological processes. Abiotic processes include atmospheric

### 5

photo - degradation and hydrolysis. Biological processes include biodegradation and bioaccumulation. The results are shown in Table 1 and in the attached modeling output f ile. Atmospheric Photodegradation Vapor-phase photo - oxidation is mediated by reaction with hydroxylradicals (HO) using submodel AOP v1.92. An overall HO - mediated rate constant of 18.3786 E - 12 cm3/molecule sec was calculated. Using an assumed HO concentration of 1.5 E6 HO molecules/cm3 and 12 hours daylight per day, an atmospheric photo - oxidation half - life of 7 hours was calculated for S - P1400. Note that a fraction of this compound (3.69 to 39.6% by two estimation methods) may become adsorbed to airborne particulates including aerosols and be resistant to atmospheric photo - oxidation. Hydrolysis The stability

of S - P1400 in water as controlled by hydrol ys is is calculated using the submodel HYDROWI

N v2.00. The submodel calculates hydrol ys is rates using str uctural features of the molecule. Using the submodel, a second- order rate constant at 25  C for pH >8 of 4.804 E - 2 L/mol sec is calculated. Half - lives at pH 7 and pH 8 of 4.6 years and 167 days, respectively, were also calculated for S - P1400. Biodegradati on EPI Suite v4.0 contains a submodel BIOWIN v4.10 that is composed of seven calculation methods. Each of the methods relies on structural features of the molecule to make its calculation. Five of the models predict generalized rates of biodegradation (e.g ., “biodegrades fast” or “does not biodegrade fast”). Two models give results for primary or ultimate biodegradation in a timeframe (e.g., “weeks” or “days”). One model estimates biodegradability

under anaerobic conditions. All four models that estimate aerobic degradation as a relative rate conclude that S - P1400 “biodegrades fast”. Primary and ultimate biodegradation half - lives are predicted to be “days” and “weeks”, respectivel y. Under anaerobic conditions, the prediction for S P1400 is that it “does no t biodegrade fast”. BIOW IN v4.10 then gives an overall concluding estimate of ready biodegradability . If the BIOWIN3 model (ultimate survey model) gives a timeline of “weeks” or faster and if the BIOWIN5 model (MITI linear model) gives a probability ≥0.5 , then the prediction is “yes” the compound is readily biodegradable. Based on this approach, the concluding prediction regarding the ready biodegradability of SP1400 is “yes”, it should pass the ready biodegradation test.

Bioaccumulation The BCFBAF Program v3.01 is used to estimate bioconcentration factors (BCF) and bioaccumulation factors (BAF). BCFBAF v3.01 uses the Arnot- Gobas BCF and BAF Method that include calculation of biotransformation rates for various aquatic trophic levels (lower, mid, upp er). The model relies on structural features of the molecule to make the calculations. BCF are calculated for aquatic organisms assuming exposure is via the surrounding water only . BAF are calculated for aquatic organisms assuming exposure is via the surro unding water and food. For S - P1400, BCF of 13, 18, and 20 L/kg were calculated for organisms inhabiting lower, mid, and upper trophic levels, respectivel y. BAF of 13, 18, and 21.5 L/kg were calculated for organisms inhabiting lower, mid, and upper trophi c levels, respectivel y. Wastewater Treatability The sewage treatment plant fugacity model (STP Fugacity Model) is used to predict the fate of substances in wastewater treatment facilities. The STP Fugacity Model estimates the fate of a substance in a generic defined facility . The calculated overall removal rate for S - P1400 was 85%, with the remaining 15% discharged. Nearly all of the removal was via adsorption to primary and secondary sludges. Level III Distribution Modeling The Level III fugacity-base d distribution model that is part of EPI Suite v4.10 relies on the physical properties that are calculated by the various submodels described above. The model calculates the distribution of a substance among all compartments of a hy pothetical environmental region. Also calculated are the relative masses that are lost through degradation processes and the masses that are removed due to advection from the modeled system. An overall persistence (Pov) is calculated that accounts for all degradation, transport, diffusive, and partitioning processes together and is expressed as an overall half

- life. The model used an Hc value of 2.45 E - 9 atm m3/mol, a VP of 3.06 E - 5 mm Hg, a supercooled liquid VP of 3.43 E - 5 mm Hg, an MP of 30  C, a Log Kow of 5.29, and a soil Ko c of 7160 L/kg. Calculated half - lives for S - P1400 that were used in the modeling were 14, 360, 720, and 3240 hours in air, water, soil, and sediment, respectively . The model was run assuming that missions to air, water, and soil are equal. The resulting distribution was <1% in air, 15.6% in water, 81% in soil, and 3.34% in sediment. The overall percent that was reacted was 87.3%, with the remaining 12.7% advected from the system. The Pov half

- life of S - P1400 was calculated to be 789 hours or 33 days. **E COTOXICITY** 

### 7

The submodel ECOSAR Program v1.00 is used to calculate the potential toxicity of substances using the log Kow value and structure activity relationships developed for various taxa of aquatic organisms. For the class of compounds “esters”, SARs are available for acute and chronic freshwater and marine fish, invertebrates, and green algae (freshwater onl y). For compounds like P1400 with a Log Kow greater than 5.0 (Log Kow is calculated to be 5.29 for S - P1400), no effects at saturation are predicted for acute fish and invertebrates. A freshwater fish chronic value of 0.023 mg/L, a daphnid chronic value of 0.207 mg/L, a green algae chronic value of 0.168 mg/L, and mys id shrimp acute and chronic values of 0.145 and 0.011 mg/L, respectively, were cal culated and are below the predicted water solubility of 0.29 mg/L. **PBT ASSESSMENT** Internationall y recognized criteria have been developed to assess a compound’s potential to be a persistent, bioaccumulation, and toxic compound (PBT). Persistence is defined b y either comparing environmental compartment specific criteria to measured or modeled data or to an overall persistence value. For persistence, cutoff values of 2 days in air, 60 days in water or soil, and 180 days in sediment are often used. The overall persistence cutoff is 180 days. For bioaccumulation, a BCF or BAF of 5000 L/kg are used. Toxicity cutoff values vary

depending on the data availability (i.e., acute or chronic). A chronic toxicity cutoff value of 0.1 mg/L is often used. Half - lives in air, water, soil, and sediment were calculated for S - P1400 to be 0.58, 15, 30, and 135 days, respectively . The Pov was calculated to be 33 days, indicating that S P1400 would not meet the persistence criteria. The BAF for the upper trophic level aquati c organisms was calculated to be 13 L/kg for P1400 and would not meet the threshold for bioaccumulation potential. The modeled ecotoxicity values showed no toxicity at saturation with most of the SAR. However, four chronic SAR predicted toxicity values (fi sh, daphnids, green algae, mys ids) were below the aqueous solubility of 0.29 mg/L. The uncertainty in the calculated ecotoxicity results do not enable comparison to toxicity

thresholds. However, since S - P1400 does not meet either the internationall y recognized persistence or bioaccumulation cutoff values, it cannot be considered a PBT. **REFERENCE** US EPA. (2011).

---------------------------------------------- Criteria for the YES or NO prediction: If the Biowin3 (ultimate survey model) result is "weeks" or faster (i.e. "day s", "days to weeks", or "weeks" AND the Biowin5 (MITI linear model) probability is >= 0.5, then the prediction is YES (readily biodegradable). If this condition is not satisfied, the prediction is NO (not readily biodegradable). This method is based on a pplication of Bayesian analysis to ready biodegradation data (see Help). Biowin5 and 6 also predict ready biodegradability, but for degradation in the OECD301C test only; using data from the Chemicals Evaluation and Research Institute Japan (CERIJ) databa se.
