Executive Summary 

Sodium and calcium hypochlorite, better known as bleach, were first registered for use as 

sanitizers and disinfectants of surfaces, as disinfectants of water, and as chemicals to control 

microorganisms on certain foods and in certain industrial processes in 1957. Sodium and 

calcium hypochlorite are chlorinated inorganic disinfectants used in laundries, swimming pools, 

ponds, drinking water, and other water and wastewater systems; on food and non-food contact 

surfaces; and as a postharvest, seed or soil treatment on various fruit and vegetable crops. Other 

specific use sites are commercial and industrial cooling tower and evaporative condenser water; 

hospital premises and contents; food processing plant equipment and premises; and toilet bowl 

and general household cleaners. The hypochlorites control bacteria, fungi, and slime-forming 

algae. There are four hundred twenty-six products containing sodium hypochlorite and 120 

products containing calcium hypochlorite. The active ingredient declarations range from 

0.0095% to 35% sodium hypochlorite and from 0.542% to 73% calcium hypochlorite. The 

Agency has evaluated the existing product chemistry data base and has determined that no 

additional data are required for reregistration review; all product chemistry data requirements 

have been satisfied for the active ingredients sodium and calcium hypochlorite salts. 

Due to uniqueness of these two chemicals (being inorganic pesticides), conventional fate 

data is neither present nor required. The Agency has evaluated the existing chemical information 

and properties on sodium and calcium hypochlorites, their reaction products and use patterns and 

has determined that no additional data are required for reregistration review. The environmental 

fate of these compounds is complex but is known based on inorganic and oxidation/reduction 

chemistry. Both sodium and calcium hypochlorite are highly reactive and except for commercial 

and industrial cooling tower and swimming pool and pond applications the existing application 

rates and use patterns are expected to be consumed prior to any possible discharge or emission to 

the terrestrial or aquatic environments. Use patterns with potential nontarget exposure to total 

chlorine residue include commercial and industrial cooling towers. 

All ecological effects data requirements for sodium and calcium hypochlorite have been 

satisfied since the Registration Standard was issued in 1986. Upon reevaluating these data, EPA 

has concluded that the currently registered uses of the hypochlorites will not result in 

unreasonable adverse effects to the environment.

Introduction 

Sodium and calcium hypochlorite, better known as bleach, are widely used compounds 

whose chemical and toxicological properties are extensively documented in published literature. 

These chemicals were first registered for use as pesticides in 1957. Four hundred twenty-six 

products containing sodium hypochlorite and 120 products containing calcium hypochlorite are 

currently registered which are listed in Table 1 and 2 in Appendix A, respectively. EPA issued a 

Registration Standard for sodium and calcium hypochlorite in February 1986. The Agency 

concluded that no additional scientific data would be necessary to register or reregister products 

that contain sodium hypochlorite declarations of 5.25% to 12.5%, or calcium hypochlorite of 

65% to 70%, as long as the products contain no other active ingredients, contain no inert 

ingredients other than water, and bear Toxicity Category I labeling. EPA still supports these 

basic findings. A Reregistration Eligibility Decision (RED) was issued by EPA for sodium and 

calcium hypochlorite salts in February 19921

. 

Sodium and calcium hypochlorites are chlorinated inorganic disinfectants. Sodium 

hypochlorite is normally sold only as a liquid while calcium hypochlorite is principally sold as a 

solid, powder, granular, or tablet product. Manufacturing-use sodium hypochlorite and calcium 

hypochlorite products are 12.5% and 65% respectively. Sodium and calcium hypochlorites are 

registered for use as terminal sanitizing rinses of food handling utensils, as sanitizers and 

disinfectants of surfaces, as disinfectants of water, and as chemicals to control microorganisms 

on certain foods and in certain industrial processes. For a detailed listing of the use patterns/use 

sites see Appendix A (Tables 3). 

Use Patterns 

Current sodium and calcium hypochlorite end-use products are labeled for use as: 

 sanitizers of surfaces (e.g., wooden butcher blocks, stainless steel tops, concrete floors, 

tile walls); or 

 sanitizers of commercial and household laundry; or 

 agents to wash or assist in lye peeling of fruits and vegetables (sodium hypochlorite 

only); or 

 agents to help control microorganisms on mushrooms (pins), potatoes, sweet potatoes 

(postharvest), pimento and tomato seeds, pecans, fish fillets, refining sugar (calcium 

hypochlorite only); or 

 agents to help control microorganisms on eggs for human consumption; or 

 disinfectants of poultry drinking water; or 

 disinfectants of human drinking water (emergency/public/individual), swimming pool 

water, hubbard/ immersion tank water, spas/hot tub, hydrotherapy pools, human drinking 

water systems (e.g., water mains); or 

 disinfectants of nonporous hard surfaces (e.g., tile, glass, stainless steel, fiberglass); or 

 agents to help control microorganisms in sewage, wastewater, industrial and pulp and 

paper process water systems; or 

 algicides/slimicides in cooling towers or 

 evaporative condensers; or

The Agency has conducted a review of the available product chemistry, environmental 

fate, and ecotoxicity data for sodium and calcium hypochlorite salts. The primary source of 

information for this assessment was the 1986 Registration Standard and 1992 sodium and 

calcium hypochlorite salts RED. The findings are summarized below.

B. Environmental Fate Summary 

In order to understand the fate of sodium and calcium hypochlorites in environmental 

media, a few general aspects of their behavior in aqueous medium is helpful. Critical to this is 

an understanding about chlorine and its interaction with water and compounds in water. 

 Chlorine is one of the most versatile elements, particularly in regards to its reaction with 

oxygen. Chlorine can take on numerous oxidation states (+7, +5, +4, +3, +1, 0, and -1)2

. 

The following diagrams illustrate a number of facts regarding the oxidation state and 

reaction products with chlorine under acidic and basic conditions: 

o a) From the highest oxidation state of chlorine in the perchlorate ion (ClO4

-

) of +7 

to -1 in the chloride ion (Cl-

) the reduction potentials3 are such that the reactions 

take place spontaneously in acidic or basic aquatic medium; and 

o b) The reverse reactions such as Cl- (oxidation -1 state) to ClO4

-

 (chlorine 

oxidation state +7) are not spontaneous.

 Sodium hypochlorite (NaOCl) and calcium hypochlorite (Ca(OCl)2) both react with water 

to form hypochlorous acid (HClO) as shown in the two reaction equations below; the 

reaction is irreversible. It is HClO which is the active disinfection moiety for all 

hypochlorites in aqueous medium and is the most effective form of what is called free 

chlorine residual, which is chlorine available to kill microorganisms.

 HClO is a weak acid and depending upon pH can further breakdown or disassociate into 

a proton or hydrogen ion and a hypochlorite ion (ClO-

), the reaction is reversible. The 

antimicrobial activity of chlorine compounds depends primarily on HClO which can

 Oxidation state is a measure of the degree of oxidation of an atom which in turn represents the tendency to lose 

electrons present in the valence orbitals 

3

 Reduction potential is a measure of the tendency to acquire electrons. The more positive the redox potential is the 

greater the affinity the atom or chemical entity has for accepting electrons and to be reduced and in turn oxidizes the 

other chemical entity involved in the redox reaction. The large, positive oxidations states indicated stored chemical 

potential energy. In a chemical reaction the increase in oxidation state is known as oxidation; a decrease in 

oxidation state is known as reduction.

o The acid dissociation constant (Kdiss or Ka) of HClO is 3.4 x 10-8 (or pKa

4

 = 7.7). 

Hence at any given time, the concentration of HClO is not very high, however, as 

it gets used up—more HClO is formed and so on. It also means that at pH 7.7, the 

ratio of HClO to ClO-

 is 50:50, while at pH 7.2, 70% is HClO and 30% is ClO-. 

o A literature report (Connell, 1996) estimated the changes due to protolysis 

(hydrolysis) of a solution containing ClO-. The graphical data is converted into 

the numerical data on the percent of HClO and ClO-

 from pH 4 to 11 as shown in 

the table below. In dilute aqueous solutions these reactions occurs in seconds or 

even in less time. This is typical of inorganic reactions.

o Disinfection is more efficient at lower pH than at higher pH because HClO is a 

more efficient disinfectant than ClO-

, and as indicated above there is a higher 

proportion of HClO at lower pH than at higher pH values. 

 It is ClO- and/or HClO moieties that are the actives for sodium and calcium hypochlorites 

under environmental conditions between pH 4 and 11. 

 Available chlorine (AC) is a measure of the equivalent weights of oxidizing agents, with 

chlorine gas as a basis—i.e., normalizes chlorine-containing compounds to allow 

comparison of oxidizing potential. The concentration of hypochlorite (or any other 

oxidizing disinfectant) may be expressed as available chlorine by determining the 

electrochemical equivalent amount of elemental chlorine (Cl2) to that compound (USEPA 

1986). 

o A mole of chlorine gas reacts with water to form a mole of HClO and a mole of 

protons (or hydrogen ions) and a mole of chloride ions. The oxidation state of 

chlorine is 0 in chlorine gas, +1 in HClO and -1 in Cl-

, therefore chlorine is both 

oxidized and reduced in this reaction.

o Elemental Cl2 oxidizing potential: one mole of elemental chlorine is capable of 

reacting with two electrons to from inert chloride, as shown in the reaction

o ClO-

 oxidizing potential: one mole of ClO- may react with two electrons to form

hypochlorite is equivalent (electrochemically) to one mole of elemental chlorine, 

and may be said to contain 70.91 grams of AC (identical to the molecular weight 

of Cl2) (USEPA, 1986).

o Since NaOCl and Ca(OCl)2 contain one and two moles of ClO-

 per mole of 

chemical, respectively, they also contain 70.91 grams and 141.8 grams of AC per 

mole (USEPA, 1986) (see the equations in the following bullet). Given that the 

molecular weight of these two compounds is respectively 74.5 and 143, pure 

preparations of the two compounds contain 95.8% and 99.2% AC—the AC per 

mole of the chemical divided by the molecular weight of the chemical (USEPA, 

1986) (see the equations provided in the following bullet). 

o The weight percent of AC (%AC) from a given weight percent of a NaClO or 

Ca(OCl)2 solution or mass can be calculated by multiplying the weight percent of 

the chemical by the fractions 0.958 and 0.992, respectively.

 Because each mole of Ca(OCl)2 can form two moles of ClO-

 rather than one mole like 

NaOCl, a mole of Ca(OCl)2 will be twice as strong as a mole of NaOCl. 

 The term “free available chlorine” is used to refer to the total of concentrations of Cl2, 

HOCl, and OCl-

, each expressed as AC. 
 Page 9 of 31

 Prolonged storage of NaOCl in storage tanks (reduces pressure) can result in the 

formation of a more hazardous chemical—sodium chlorate (NaClO3). This is one 

concern about sodium hypochlorite kept over a long period of time in storage.

 Under direct sunlight, hypochlorite decomposes into hydrogen chloride and oxygen. 

Under prolonged sunlight exposure there is a likelihood of the formation of chlorate ion 

(ClO3

-

) in small quantities. 

 Chlorine in addition to providing disinfection or oxidation of microorganisms can be 

consumed by oxidation or substitution reactions with inorganic substances such as 

ammonia, iron, manganese, sulfides and some other organic substances (e.g., phenols). 

 In the surface water and wastewater streams possible transformation products like 

chlorine, HOCl, ClO3

-

 may be present, but the determination of exact amounts of these 

moieties cannot be calculated as these will depend on the environmental conditions like 

pH of the medium, temperature, ionic strength, etc. 

 Chlorine in addition to providing disinfection or oxidation of microorganisms can be 

consumed by oxidation or substitution reactions with inorganic substances such as 

ammonia, iron, manganese, sulfides and some other organic substances (e.g., phenols). 

Environmental Fate and Transport of Sodium Hypochlorite and Calcium Hypochlorite 

Sodium hypochlorite is a very active substance and dissociates immediately in water to 

produce OCl-

. Depending on the pH of the medium, it has the capability to go through chemical 

transformation to ClO2

-

 , Cl2, Cl- and under highly acidic and basic conditions it can chemically 

transform into ClO3

-

 and ClO4

-

, depending under the oxidizing or reducing conditions of the 

medium. Thus a conventional way of looking at the environmental data (hydrolysis, aquatic 

photolysis, aerobic/anaerobic aquatic metabolism) is not possible and therefore such data is not 

required. 

EPA completed a RED on Sodium and Calcium Hypochlorites in 1991 (USEPA, 1991) 

and did not require any environmental fate data. EPA concluded that the fate requirements for 

these chemicals can be considered satisfied based on the information provided in the1981 

Ambient Water Quality Criteria for Chlorine (J. Tobler, EPA; June 1981); the last revision to the 

Ambient Water Quality Criteria for Chlorine occurred in 1984 (USEPA, 1985). These 

documents discuss reaction equations of chlorine, total chlorine residual (TCR), effects of TRC 

on aquatic organisms, and ambient water quality criteria for TRC. Dissipation and 

transformation chemistry of chlorine and the hypochlorites, in water and with inorganics and 

organic molecules is also discussed in the EPA Municipal Wastewater Disinfection Design 

Manual (USEPA, 1986). 

In 2007, the OECD published a Screening Information Data Set (SIDS) on calcium 

hypochlorite (OECD, 2007) which also reviews chlorine reactions; the document concludes that 

additional assessment on chlorinated by-products should be pursued. European Commission’s

and Environmental Risks (SCHER) completed its Risk Assessment Report (RAR) on Sodium 

Hypochlorite in 2008 (EU, 2008). This report concluded generally sodium hypochlorite is a very 

reactive moiety and transforms into so many other substances fast, so an actual environmental 

risk assessment cannot be conducted; however for certain use scenarios there is the potential for 

formation of such substances like organic halogens (AOX), haloacetic acids (HAA), and 

trihalomethanes (THM), for which effects on aquatic organisms can be assessed. These 

inorganic moieties like OCl-

, ClO2, and ClO3

- etc. in aqueous systems undergo changes by 

themselves, through pH changes, and hence Agency guidelines for environmental fate and 

transport cannot be used to evaluate their fate characteristics in media like water and 

soils/sediments. 

All environmental fate information requirements for sodium and calcium hypochlorite 

and reaction products have been satisfied. 

Water Quality 

Sodium and Calcium Hypochlorites are not identified as a cause of impairment for any 

water bodies listed as impaired under section 303(d) of the Clean Water Act, based on 

information provided at the Agency’s National Pesticides Cause of Impairment of Waters 

website (searched November 11, 2011)5

. In addition, no Total Maximum Daily Loads (TMDL) 

have been developed for sodium and calcium hypochlorites, based on information provided at 

the Agency’s National Pesticide TMDL web site (searched November 11, 2011)6. More 

information on impaired water bodies and TMDLs can be found at 

http://www.epa.gov/owow/tmdl/. The Agency invites submission of water quality data for this 

pesticide. To the extent possible, data should conform to the quality standards in Appendix A of 

the OPP Standard Operating Procedure: Inclusion of Impaired Water Body and Other Water 

Quality Data in OPP’s Registration Review Risk Assessment and Management Process (see: 

http://www.epa.gov/oppfead1/cb/ppdc/2006/november06/session1-sop.pdf ), in order to ensure 

they can be used quantitatively or qualitatively in pesticide risk assessments.

C. Ecological Effects Summary 

A summary of ecological effects data that is available in-house is summarized in Table 8. 

The Ambient Water Quality Criteria for Chlorine – 1984 document contains a review of public 

literature on effects of chlorine (total residual chlorine) and based on the data derives freshwater 

and saltwater organism acute and chronic water quality criteria. Current ambient water quality 

criteria for chlorine are based on the data in the 1984 document and the method for deriving 

water quality standards discussed in a 1986 Water Quality Document (USEPA, 1986). 

 Freshwater Criterion Maximum Concentration = 19 μg/L; 

 Freshwater Criterion Continuous Concentration = 11 μg/L; 

 Saltwater Criterion Maximum Concentration = 13 μg/L; and 

 Saltwater Criterion Continuous Concentration = 7.5 μg/L
