1 KELSEY KORNAUS CBE 555 MARCH 1, 2010 Cleaning with Clorox

2 Disinfecting vs. Cleaning Cleaning  General removal of debris  Dirt  Dust  The more cleaning done, the easier it is to disinfect Disinfecting  Removing germs and viruses that live on surfaces and lead to infection  Provides extra margin of safety

3 Cleaning

4 Soil Types Organic  Fat, grease, protein, carbohydrate, mold, yeast, bacteria, petroleum soils  Best removed by alkaline cleaners or solvents Inorganic  Rust, scale, hard water deposits and minerals such as sand, silt and clay.  Best removed by acidic cleaners Combination

5 What’s in these cleaners? Surfactants Chelating Agents Builders Solvents

6 Surfactants Wetting agent that lowers surface tension “Surface Active Agent” Roll-up mechanism Emulsification


8 Chelating Agents What are they used for?  Water hardness is a big problem  Presence of calcium, magnesium, iron and manganese metal ions How do they do it?  Chelating agents surround ions and alter electronic charge of metal ions from positive to negative  “Chemicals that form soluble, complex molecules with certain metal ions, inactivating the ions so that they cannot normally react with other elements or ions to produce precipitates or scale.” -ASTM What are some of the problems?  Interfere with cleaning ability of detergents  Environmental factor  Builders used instead

9 Most Common Chelating Agent EDTA  Can form 4-6 bonds  Useful in cleaning because forms complexes with calcium and magnesium ions (hard water)

10 Water May contain as much as 90% to 95% water! Water can be considered an active ingredient that actually adds to the detergency of cleaners. Water acts as a solvent that breaks up soil particles after the surfactants reduce the surface tension and allow the water to penetrate soil Aids in suspension

11 Preservatives Prevents against natural effects of aging such as decay, discoloration, oxidation and bacterial degradation Prevents agains rancidiity and oxidizing  Butylated hydroxdytoluyene (BHT)  Stannic Chloride Prevent bacteria from spoiling product  Methyl paraben  Propyl paraben

12 Disinfecting

13 Why Disinfect? List of organisms around the house  Bacteria Staphylococcus aureus (Staph.) Salmonella choleraesuis Pseudomonas aeruginosa Streptococcus pyogenes (Strep.) Escherichia coli O157:H7 (E. coli) Shigella dysenteriae Methicillin Resistant Staphylococcus aureus (MRSA) Fungi Trichophyton mentagrophytes (can cause Athlete's Foot) Candida albicans (a yeast) Viruses Rhinovirus Type 37 (a type of virus that can cause colds) Influenza A (Flu virus) Hepatitis A virus Rotavirus Respiratory Syncytial Virus (RSV) HIV-1 (Human Immunodeficiency Virus)* Herpes simplex Type 2 Rubella virus Adenovirus Type 2 Cytomegalovirus Laundry  Washing with laundry detergent alone can leave behind invisible dirt embedded deep in fibers, as well as the cause of the yellow stain-body oil which eventually provides a haven for bacteria and dust mites

14 Common Household Bleach Active Ingredient- Sodium hypochlorite at 5.25% strength in water based solution  Manufactured by mixing chlorine with sodium hydroxide and water NaOCl + H 2 O ↔ HOCl + Na + + OH -

15 Salt + Water Sodium HydroxideSodium Hydroxide HydrogenHydrogen ChlorineChlorine Sodium Hypochlorite Stains + Soils The Bleach Cycle

16 Recent News Environmental groups, mainly Greenpeace, have been encouraging Congress to instate tough chemical plant security legislation November 2009 Clorox announces it will stop making bleach as they always have out of chlorine and sodium hydroxide Eliminate risk to more than 13 million Americans who live in range of Clorox facilities According to the Clorox web site: “Except for quality control improvements, Clorox bleach remains unchanged since its introduction to American consumers in 1916.”

17 Good Decision Bad Decision Carbon footprint of shipping 15% 16 trucks vs 1 rail car Someone else is still a target Less of a target Safety increases!

18 How it works? Whiten  Oxygen in bleach breaks up chemical bonds of chromophores making them incapable of absorbing any visible light  Same concept as sunlight fading colors on clothes Germ-Killer (Microbial killer)  Protein coagulation  Same principle in human body which produces hypochlorous acid to kill bacteria in case of any infection  Disruption of cell membrane- allows passage of disinfecting molecules  Removal of free sulphydryl groups- amino acid side groups tied down  Chemical antagonism- Substrate recognition

19 All Cleaning Products Why can’t we put all these together in one?!

20 Bleach + other cleaning agents Ammonia  2NH 3 + NaOCl -----> N 2 H 4 + NaCl + H 2 O Poisonous  3NaOCl + NH3 --> 3NaOH + NCl3 Volatile and Explosive  2(parts)NaOCl + 2NH3 --> 2NaONH3 + Cl2. Toxic Acids  HOCl + HCl ↔ H 2 O + Cl 2 ↑ Toxic “Bad News Bears”

21 New Bleach Technology What can be done to make it better?


23 Business History of Bleach Marketing  Clorox Brand vs. Generic Brand  Building Brand Equity  New Approach Special Events

24 History of Bleach

25 Clorox Today “We had a very good second quarter, especially given the continued challenging economic environment," said Chairman and CEO Don Knauss.

29 What else is there to a business? Blue Sky Project- Clorox will provide half of the purchase price of “The Blue Sky Project: A Clorox Charity Collection” to benefit Music In Schools Today (MuST). “Year of the Frog” Sponsor and collaborated with Animal Planet to produce a documentary titled “The Vanishing Frog” (chytrid (KIT-rid) fungus)
