Household Bleach (1L)

Material Composition Assumptions

The assessment assumes a standard household bleach solution containing sodium hypochlorite as the primary active ingredient at typical commercial concentrations. The product consists of sodium hypochlorite representing approximately 53 grams of the total solution weight, with sodium hydroxide stabilizer contributing roughly 8 grams for pH balance. Water forms the bulk composition at approximately 1,020 grams, while trace amounts of hydrogen peroxide and calcium hypochlorite provide additional stabilization totaling about 2 grams. The high-density polyethylene packaging container adds approximately 85 grams to the total product weight, bringing the complete packaged product to roughly 1,085 grams.

Manufacturing Geography

Production centers primarily in China due to the country’s dominant position in chlor-alkali chemical manufacturing and cost-effective industrial infrastructure. Chinese facilities benefit from integrated chemical production complexes that efficiently produce both chlorine and sodium hydroxide through electrolytic processes. The electricity grid intensity of 555 gCO2e/kWh significantly influences the carbon footprint of the energy-intensive chlorine production process. Manufacturing concentration in this region also reflects proximity to major plastic resin production facilities for packaging materials and established supply chains for global distribution.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2e/kWh	52	Baseline
European Union	275 gCO2e/kWh	38	-27%
United States	386 gCO2e/kWh	44	-15%
India	708 gCO2e/kWh	61	+17%
Brazil	87 gCO2e/kWh	28	-46%

Provenance Override Guidance

1. Electricity source documentation for chlor-alkali production facilities including renewable energy certificates or on-site generation data to adjust grid intensity assumptions.

2. Packaging material specifications including recycled content percentages, alternative container materials, or lightweighting initiatives that reduce plastic consumption per unit.

3. Transportation and logistics data covering shipping distances, modal splits between truck and rail transport, and distribution center locations for accurate freight emissions.

4. Chemical production efficiency metrics such as energy consumption per kilogram of sodium hypochlorite produced and process technology specifications for chlorine generation.

5. Waste management protocols including treatment methods for production wastewater, packaging material recovery programs, and end-of-life disposal pathways.

Methodology Notes

• The CCI score represents cradle-to-gate emissions for one liter of household bleach including packaging but excluding consumer use phase and disposal impacts.

• Scope 1 emissions dominate due to direct chemical synthesis processes, while Scope 3 captures significant packaging and transportation contributions reflecting the product’s high water content and weight.

• The functional unit assumes standard 5.25% sodium hypochlorite concentration typical of consumer bleach products sold in retail markets.

• Exclusions include consumer storage, dilution during use, wastewater treatment of discharged bleach solution, and recycling of plastic containers due to variable regional practices.

• Data gaps exist around specific production facility efficiency variations, alternative stabilizer formulations, and regional differences in packaging design standards.
