2 Introduction EKA CHEMICALS HAS MAINTAINED ITS POSITION AS A WORLD LEADER IN INNOVATIVE TECHNOLOGY BY TEAMING UP WITH OTHER AKZO NOBEL CHEMICAL GROUPS TO PROVIDE A VARIETY OF PRODUCTS FOR OXIDATIVE CLEANING AND BLEACHING APPLICATIONS. PEROXY-BLEND IS A UNIQUELY STABILIZED SPECIALTY OXIDANT, SPECIFICALLY DESIGNED TO BE MORE ROBUST WHEN USED FOR BUILDING OXIDATIVE CLEANING FORMULATIONS. ITS STABLE OXYGENATED CLEANING COMPONENT PROVIDES A CHLORINE- FREE ALTERNATIVE FOR CLEANING AND STAIN REMOVAL. WHEN COMBINED WITH AKZO NOBEL SPECIALTY SURFACTANTS, THE ACTION OF OXYGEN MICRO-BUBBLES CAN BE PARTICULARLY EFFECTIVE AT LIFTING AND REMOVING DIFFICULT SOILS FROM A VARIETY OF FABRICS AND HARD SURFACES. But why should you use? Because it gives you an advantage The Advantage. The Advantage Enhanced Cleaning Stable Oxygen Bleaching Alternative, Even at Alkaline ph Odor Elimination Soil Dispersion, Inhibiting Re-deposition Robust Nature for Formulation and Compounding Corrosion Inhibition of Metal Parts Stability in Thickened Formulations Chlorine-Free, Environmentally Friendly brings Many Benefits to All These Products Deck Wash Carpet Cleaners Liquid Laundry Table of Contents All Purpose Cleaner Sanitizers Introduction/Background The Advantage Formulation Stability Why Use? Technical Data/Safety & Handling..7 Vehicle Wash Thickened Formulations Kitchen & Bath Cleaner...To Mention Just a Few.

3 The Advantage in Soil Breaking Chemical oxidation increases hydrophilicity of soils and reduces adhesion at the surface The Result... Enhanced water solubility Better cleaning! in Soil Dispersion Encapsulates soil particles, forcing them apart... Soil The Result... Does not allow particle agglomeration Reduced re-deposition Better cleaning! in Odor Elimination Chemical oxidation of odor generating compounds... H 2 S + Rotten egg smell 2 H 2 O + S Water Sulfur The Bleaching Effect Chemical oxidation of color bodies or chromophores can provide a bleaching effect The Result... A cleaner, fresher experience Better cleaning! Color body Bleached Body The Result... Spot and stain removal on fabrics and hard surfaces Brightening effect in laundry applications No fabric degradation 3

4 Formulation Stability "STABILITY" It means different things to different people. Basically, it can be defined as a "lack of change." To a consumer, it means that the cleaner works the same whether fresh out of the bottle or months old. To a formulator, it can mean having a successful product or an endless stream of headaches. It can mean having just one recipe that always produces the same product with the same performance. It means knowing that the product described on your batch sheets really is the same one that will end up in the customers hands. Nowhere has there been more of a challenge in this respect than with oxidizers in formulations and, in particular, hydrogen peroxide. Hydrogen peroxide, because of its chemical nature, will break down in the presence of organic/metallic compounds and/or heat. Peroxide decomposes into oxygen and water. Conventional hydrogen peroxide tends to undergo this transformation almost immediately upon blending into a formulation. The result is a significant loss of oxidizing and, hence, cleaning power. % Decomposition Formulation Elevated Temperature Technical Grade Peroxy-Blend Elapsed Time (days) Metals Doping Level (mg metal per gram HP) 0.20 to to 80 Remaining Oxidant after 18 to 24 Hours Tech Grade Hydrogen Peroxide Remaining (%) The figure above shows a dramatic gain in temperature stability with. These formulations are Low-Foaming type cleaners utilizing Akzo Nobel surfactants. The unique stabilizing technology devised by Akzo Nobel gives significant performance advantages over standard grades of hydrogen peroxide. These additives also give other useful properties that bring added capability to any formulation incorporating it. 4

5 Alkaline Formulations with Oxidizer Content (gm/liter) Alkaline Formulations with The chart to the left illustrates how is superior to technical grade hydrogen peroxide at elevated ph. While carbonate is not recommended, caustic soda provides a simple and effective means of raising ph. Initial 48 Hours The Advantage vs. Other Oxidizers High ph Low ph Metals Chlorine Free Effect on Surfactants Hypo (chlorine bleach) (+) (-) (-) (-) (-) Peracetic Acid (-) (+) (-) (+) (+) Persalts (Percarbonate, etc.) (+) (-) (-) (+) (+) Hydrogen Peroxide (-) (+) (-) (+) (+/-) (+) (+) (+) (+) (+) Rheology of Formulations with and Elfacos T-212 Viscosity (cps) y=0.3273e 3.744x 1400 R 2 = Berol 226SA is at 5%wt. Peroxide from is at 5%wt. The balance is water T-212 Concentration (wt%) Thickening with The graph to the left shows how predictable thickening of Peroxy- Blend formulations can be when Berol products are used. The correlation coefficient of indicates a very strong exponential relationship. This illustrates a system with very reliable thickening performance. 5

6 Metal Cleaning With The photo to the right shows the result of common copper wire exposed to a standard peroxide/sulfuric micro-etch for 30 seconds. The rapid oxidation of the newly exposed copper is to be expected. The Peroxy- Blend /sulfuric acid combination shows a protected surface free of oxidation. This condition has been documented to be in place 6 weeks after treatment. Why Use? allows the incorporation of a powerful oxidizing agent into commercial products, even when a separate facility to handle hydrogen peroxide/bleach is not available. is opening new opportunities for formulators to offer: Soil Breaking Color Stain Removal Odor Elimination Improved Soil Dispersion Environmentally Friendly Products 6

Approximate ph of this formulation is 10.5 Add the Berol 226SA last.
