1. PERCHLOROETHYLENE Alternatives Identification Jason Marshall Heidi Wilcox 11/09/05

3. Dry Cleaning – Garment Alternatives Hydrocarbons Exxon DF 2000 Fluid, Chevron EcoSolv and Shell SHELLSOL Isoparaffins, synthetic hydrotreated aliphatic hydrocarbons without an odor, flash pt >140 F Hydrofluoroether, Perfluorocarbon, Hydrocarbon Pure Dry Uses DF 2000 as the hydrocarbon Volatile methyl siloxane Green Earth GE Cyclopentasiloxane (decamethylcyclopentasiloxane) Glycol Ether Rynex Substituted aliphatic glycol ethers Dipropylene glycol tertiary-butyl ether DPTB n-propyl bromide (nPB) Comexsol - limited plans to market

4. Dry Cleaning – Garment Alternatives Traditional Wet Cleaning Water, conditioners, degreasers and detergent Icy Water DWX 44 Water, detergent, conditioners and degreasers Equipment designed to minimize temperature and agitation Green Jet DWX 44 Mist of water and detergent to clean the garments Carbon Dioxide Liquid carbon dioxide under a pressure of 700 psi

5. Dry Cleaning – Spot Cleaning Alternatives Adhesive Remover Beverage Stains Food Stains General Stains Ink Stains Nail Polish Oil Stains Protein Stains Rust Silk Spotter Tannins Waxes

6. Metal Cleaning / Degreasing – Vapor Degreasing Alternatives Hydrofluoroether (HFE) 3M HFE 7100, 7200, 71DE Volatile methylsiloxane (VMS) Dow OS 10, 20, 30 Propylbromide (nPB) Tech Spray Solvon, EnviroTech Ensolv, Petroferm Lenium Hydrochlorofluorocarbon (HCFC) Asahi AK 225 Hydrofluorcarbon (HFC) Dupont Vertrel XF

7. Metal Cleaning / Degreasing – Other Cleaning Alternatives Solvents Hydrocarbons, petroleum distillates Semi-Aqueous Terpenes, Soy, Corn, Dibasic Esters, Alcohols Aqueous Acidic, Neutral, Alkaline, enzymatic/microbial Hundreds of alternatives evaluated by TURI with results available on-line

8. Aerosols – Auto Alternatives Auto – Tire/wheel cleaners Poly-alphaolefin Silicone emulsion, propylene glycol, propane, isobutane, dimethyl ether D-limonene, propane, non-ionic mix Orange Oil, water 2-butoxyethanol, water Aqueous emulsifier, nonionic surfactant, propane, isobutane Steam Auto – Brake cleaners Natpha, xylene, propane, toluene, benzene, methanol, ethyl benzene C9-C12 hydrocarbon, acetone, propanol Acetone, amyl acetate, CO2 Orange Oil Steam Auto – Carburetor & fuel injection Xylene, toluene, methyl ethyl ketone, acetone, methanol, 2 -butoxyethanol, isopropanol, CO2 Terpene/orange oils AQUEOUS ALTERNATIVES SHOULD NOT BE USED

9. Aerosols Auto – Engine degreasing Xylene, toluene, heptane, hexane, MEK, acetone, methanol poly-alphaolefin, synthetic oil, esters, 2-hexyl acetate, dibasic ester, CO2 2-butoxy Ethanol, Methyl Esters of C16-c18 And C18 Unsaturated Fatty Acids, Petroleum Sulfonate, Kerosene, Orange Peel Oil Sweet Cold Pressed, Nonyl Phenol Ethoxylate, CO2 D-limonene, propane, non-ionic mix Orange Oil 2-butoxyethanol, water Aqueous emulsifier, nonionic surfactant, propane, isobutane Steam

10. Aerosols Auto – Wire dry 3,3-Dichloro-1,1,1,2,2-Pentafluoropropane, 1,3-Dichloro-1,1,2,2,3-Pentafluoropropane, Acetone, CO2 Aliphatic petroleum distillate, light & heavy naptha, 2-butoxyethanol, CO2 Stoddard solvent, naptha petroleum oil mix, 2-butoxyethanol, CO2 Auto – Anti Seize Aliphatic petroleum naptha, CO2 Naptha, polydimethyl siloxane, heptane, propane, butane Stoddard solvent, paraffin petroleum distillate, CO2

11. Aerosol Summary Solvents – hydrocarbons, silicones Semi-aqueous – terpenes, esters Aqueous based Process system changes Spray to immersion Spray to ultrasonics Spray to manual
