    OTTO FUEL II AND ITS COMPONENTS 1 1. PUBLIC HEALTH STATEMENT This statement was prepared to give you information about Otto Fuel II and its components, and to emphasize the human health effects that may result from exposure to them. The Environmental Protection Agency (EPA) has identified 1,397 hazardous waste sites as the most serious in the nation. These sites make up the National Priorities List (NPL) and are the sites targeted for long-term federal clean-up activities. Otto Fuel II has been found at two of the sites on the NPL. However, the number of NPL sites evaluated for Otto Fuel II and its components is not known. As EPA evaluates more sites, the number of sites at which Otto Fuel II and its components are found may increase. This information is important for you to know because Otto Fuel II and its components may cause harmful health effects and because these sites are potential or actual sources of human exposure to Otto Fuel II and its components. When a chemical is released from a large area, such as an industrial plant, or from a container, such as a drum or bottle, it enters the environment as a chemical emission. This emission, which is also called a release, does not always lead to exposure. You can be exposed to a chemical only when you come into contact with the chemical. You may be exposed to it in the environment by breathing, eating or drinking substances containing the chemical, or from skin contact with it. If you are exposed to a hazardous chemical such as Otto Fuel II and its components, several factors will determine whether harmful health effects will occur, and what the type and severity of those health effects will be.

    PINK BOOK 3 Sebacic Acid/Dicarboxylic Acids CIR EXPERT PANEL MEETING AUGUST 30-31, 2010 Memorandum To: CIR Expert Panel Members and Liaisons From: Monice M. Fiume MMF Senior Scientific Analyst/Writer Bart A. Heldreth, Ph.D. BAH Chemist Date: July 30, 2010 Subject: Draft Report on Dicarboxylic Acids (previously called Diisopropyl Sebacate) The draft report on dicarboxylic acids was last reviewed in December 2009, under the title Diisopropyl Sebacate. At that time, the report was tabled for reorganization. Also at that time, it was determined that oxalic acid would not be part of the safety assessment. The entire report has been reorganized and rewritten. It will be obvious that the Chemistry section is now prepared in a way that allows you to view the dicarboxylic acids in order of increasing chain length. Also included are charts demonstrating the relationship between molecular weight and the log octanol – water partitioning coefficient. Additionally, the report, from the General Biology section on, is now divided into two sections, as was suggested by the Panel in December. The first section addresses dicarboxylic acids and their salts, while the second part addresses esters of dicarboxylic acids. These two subsets of ingredients have different functions in cosmetics, and this will allow the Panel to view the data on each subset separately. In addition to the reorganization, the report has change greatly in the extent of data included. A complete new search of the literature has been performed, and a substantial amount of new data has been added. A great deal of the information included in this report has come from summary documents, such as HPV robust summaries, that cite unpublished sources.

Report Title: Rapid Screening and Confirmation of Organic GSR using Electrospray Mass Spectrometry Award Number: 2009-DN-BX-K251 Author(s): Dr. Bruce McCord; Jennifer (Greaux) Thomas, BS Abstract The primary goal of this project was to develop a rapid separation and detection method for identifying common smokeless powder additives and their decomposition products using ultra performance liquid chromatography/ mass spectrometry. Smokeless powders can be used as the explosive component in pipe bombs as well as the propellant in modern ammunition. When used in ammunition, the powder is ignited by the primer and burns rapidly to produce a large volume of gas at high pressures and temperatures. It is this buildup of pressure that forces the projectile out of the firearm. In addition to the bullet, there is a release of primer chemicals and unburned/partially burned powder that may get deposited onto the shooter’s skin, hair, clothing, and in the nearby environment.

  • Toxicity Review for Diisononyl Adipate (DINA)”1 June 2019
    CPSC Staff Statement on University of Cincinnati Report “Toxicity Review for Diisononyl Adipate (DINA)”1 June 2019 The U.S. Consumer Product Safety Commission (CPSC) contracted with the University of Cincinnati to conduct toxicology assessments for nine dialkyl o-phthalate (o-DAP) substitutes: phenyl esters of C10-C18 alkylsulfonic acid esters (ASE); glycerides, castor-oil-mono-, hydrogenated, acetates (COMGHA); dibutyl adipate (DBA) and di-isobutyl adipate (DiBA); di (2-ethylhexyl) sebacate (DEHS)/dioctyl sebacate (DOS); a mixture of 98% di-2-ethylhexyl terephthalate (DEHT) and 2% 2-ethylhexyl methyl terephthalate (2-EHMT); dibutyl sebacate (DBS); diisononyl adipate (DINA); epoxidized soybean oil (ESBO); and tributyl citrate (TBC). The reports will be used to inform staff’s assessment of products that may contain these compounds and is the first step in the risk assessment process. CPSC staff assesses a product’s potential health effects to consumers under the Federal Hazardous Substances Act (FHSA). The FHSA is risk-based. To be considered a “hazardous substance” under the FHSA, a consumer product must satisfy a two-part definition. First, it must be “toxic” under the FHSA, or present one of the other hazards enumerated in the statute. Second, it must have the potential to cause “substantial personal injury or substantial illness during or as a proximate result of any customary or reasonably foreseeable handling or use.” Therefore, exposure and risk must be considered in addition to toxicity when assessing potential hazards of products under the FHSA. The first step in the risk assessment process is hazard identification, which consists of a review of the available toxicity data for the chemical.
