Cleaning with Clorox

Disinfecting vs. Cleaning

Cleaning General removal of debris

Dirt Dust

The more cleaning done, the easier it is to disinfectDisinfecting

Removing germs and viruses that live on surfaces and lead to infection

Provides extra margin of safety

Cleaning

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

What’s in these cleaners?

SurfactantsChelating AgentsBuildersSolvents

Surfactants

Wetting agent that lowers surface tension“Surface Active Agent”

Roll-up mechanismEmulsification

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

Most Common Chelating Agent

EDTA Can form 4-6 bonds Useful in cleaning because forms complexes with

calcium and magnesium ions (hard water)

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

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

Disinfecting

Why Disinfect?

List of organisms around the house Bacteria

Staphylococcus aureus (Staph.) Salmonella choleraesuisPseudomonas aeruginosaStreptococcus pyogenes (Strep.)Escherichia coli O157:H7 (E. coli)Shigella dysenteriaeMethicillin Resistant Staphylococcus aureus (MRSA)FungiTrichophyton mentagrophytes (can cause Athlete's Foot)Candida albicans (a yeast)VirusesRhinovirus Type 37 (a type of virus that can cause colds)Influenza A (Flu virus)Hepatitis A virusRotavirusRespiratory Syncytial Virus (RSV)HIV-1 (Human Immunodeficiency Virus)*Herpes simplex Type 2

Rubella virusAdenovirus Type 2Cytomegalovirus

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

BLEACH

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 + H2O ↔ HOCl + Na+ + OH-

Salt + Water

• Sodium Hydroxide

• Hydrogen• Chlorine

Sodium Hypochlorite

Stains + Soils

The Bleach Cycle

Recent News

Environmental groups, mainly Greenpeace, have been encouraging Congress to instate tough chemical plant security legislation

November 2009Clorox 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.”

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!

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

All Cleaning Products

Why can’t we put all these together in one?!

Bleach + other cleaning agents

Ammonia 2NH3 + NaOCl -----> N2H4 + NaCl + H2O Poisonous 3NaOCl + NH3 --> 3NaOH + NCl3 Volatile and

Explosive 2(parts)NaOCl + 2NH3 --> 2NaONH3 + Cl2. Toxic

Acids HOCl + HCl ↔ H2O + Cl2 ↑ Toxic

“Bad News Bears”

New Bleach Technology

What can be done to make it better?

TODAY, AN ESTIMATED EIGHT OUT OF TEN AMERICAN HOUSEHOLDS USE CLOROX® BRAND BLEACH, AND CLOROX® BRAND

LAUNDRY AND HOME CLEANING PRODUCTS ARE SOLD IN MORE THAN 100 COUNTRIES IN NORTH AMERICA, SOUTH AMERICA, EUROPE,

AFRICA AND ASIA.
