NEODOL alcohols for surfactant applicationsC9 and C91 alcohols from ShellProduced by the exclusive Shell Hydroformylation Process - selectively methyl-branchedhydrophobes, 85% linear.Addition of NEODOL 9 to our portfolio supports customer innovation in cleaning products.Increasing our light alcohol supply capabilityWe are producing NEODOL 9 at our Stanlow, UK plant for customers worldwide.We are modifying our Geismar, LA plant to produce NEODOL 9, increasing our global C9-11alcohol capacity by 50% (30 kilotons/year).Ethoxylate performance in major applicationsOur light alcohols can be derivatized to anionic or nonionic surfactants. Applications include:Hard surface cleanersRapid delivery of desired cleaning resultsCo-surfactant for compact detergents Improved handling, equivalent cleaning performance2

Co-surfactants for compact laundry formulationsCompact liquids have grown rapidly in North America and EuropeDelivering on sustainability - cut packaging and transport costs2X-3X formulas, with typical maximum ~50% active surfactant concentrationHigh active matter (HAM) blends enable super-concentrated liquidsEthoxylates of NEODOL 9 and 91 can be used with ionic surfactants, either AES or LAS, toproduce HAM blends of ~90% active matter (10% water).Key HAM requirements: acceptable physical properties for transport/handling; no gel formationwhen water-extended; no need for expensive/volatile solvents.Equivalent cleaning performanceThe detergency of formulations using light alcohol ethoxylates as non-ionic co-surfactant matchesformulations using traditional midcut ethoxlate co-surfactants.Blends of light alcohol AEs with either AES or LAS provide effective cleaning.6

Focus on NEODOL 9, our new alcoholNEODOL 9 AlcoholWe have completed successful plant trials at our Stanlow, UK facility and we planon-going manufacture.We have initiated sales of commercial (bulk) quantities.A project is planned at our Geismar, LA facility to provide manufacturing capabilityin N America in 2013.NEODOL 9-7 EthoxylateWe have produced sample quantities for customer testing. Initial customerfeedback indicates useful properties, as anticipated.We are initiating test work to more thoroughly define surfactant properties andcleaning performance of N9-7 and related high/mid-mol ethoxylates of NEODOL 9.Commercial manufacture of N9-7 and bulk supply to customers will commence inearly 2012.June 2010 9

NEODOL 9-7: an effective combination of propertiesNEODOL 9-7 matches the surfactant properties of NEODOL 91-8 (HLB and cloudpoint), but significantly lower pour point and viscosity facilitate handling.- Surfactant Properties of N9/N91 Hi-Mol Ethoxylates -N91-8 N9-7 N91-6HLB 13.7 13.7 12.5Cloud Point 81 C 77 C 54 CPour Point 15 C 7 C 6 CViscositycSt, 40 CDensity40 CFlash PointASTM D9327 22 210.996 0.992 0.976160 C 146 C 150 CHLB: Hydrophilic - Lipophilic Balance10
