Laundry Detergent (1L liquid)

Material Composition Assumptions

A typical one-liter bottle of liquid laundry detergent weighs approximately 1,120 grams including packaging. The formulation consists of builders comprising the largest portion at 560 grams or 50% by weight, primarily zeolites, sodium silicate, sodium citrate, and sodium carbonate for water softening and soil suspension. Surfactants make up 168 grams or 15% of the product weight, predominantly linear alkylbenzene sulfonates or fatty alcohol sulfates that provide cleaning action through dirt removal and foam generation.

Bleaching agents contribute 78 grams or 7% of the total weight, typically sodium percarbonate or chlorine-based compounds for stain removal and whitening. Enzymes represent a smaller but critical component at 22 grams or 2%, including proteases for protein-based stains, lipases for grease removal, and amylases for carbohydrate-based soils. The remaining 292 grams consist of fragrances derived from synthetic petroleum compounds, preservatives, colorants, and water as a carrier medium.

The packaging consists of either polyethylene terephthalate or high-density polyethylene plastic weighing approximately 45-60 grams for the bottle and closure system.

Manufacturing Geography

Liquid laundry detergent production occurs primarily in China, India, and the United States, which collectively account for over 60% of global manufacturing capacity. China serves as the dominant manufacturing hub due to established petrochemical supply chains for surfactant production and lower labor costs, operating with a grid intensity of 555 gCO2/kWh that significantly influences the carbon footprint of energy-intensive chemical processing.

Indian facilities benefit from proximity to palm oil feedstocks used in surfactant manufacturing and growing domestic demand, though grid intensity remains relatively high. United States production focuses on domestic market supply and benefits from natural gas availability for chemical processing, though regional grid intensities vary substantially between manufacturing states.

The concentration of surfactant precursor production in Asia, particularly fatty alcohol and ethylene oxide manufacturing, drives the geographic distribution of final detergent assembly operations to minimize transportation costs of bulk chemical intermediates.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2/kWh	38	Baseline
India	709 gCO2/kWh	41	+8%
United States	386 gCO2/kWh	35	-8%
European Union	253 gCO2/kWh	32	-16%
Brazil	91 gCO2/kWh	28	-26%

Provenance Override Guidance

1. Primary surfactant supplier carbon footprint data with breakdown by surfactant type (anionic vs nonionic) and feedstock source (palm kernel vs petroleum-derived fatty alcohols).

2. Packaging material specifications including recycled content percentage, material type selection between PET and HDPE options, and supplier-specific production emissions data.

3. Manufacturing facility energy consumption profile including electricity grid source verification, natural gas usage for heating processes, and facility-specific efficiency metrics.

4. Transportation logistics documentation covering raw material inbound shipping distances and modes, finished product distribution patterns, and packaging density optimization measures.

5. Product concentration factor validation showing actual grams per wash load and number of wash cycles per bottle to confirm functional unit calculations.

Methodology Notes

• The CCI score represents cradle-to-gate emissions including raw material extraction, chemical processing, packaging production, and manufacturing through distribution center delivery, but excludes consumer use phase and end-of-life disposal.

• Scope 3 emissions dominate at 91% primarily due to energy-intensive surfactant manufacturing from petrochemical feedstocks, while direct manufacturing emissions remain relatively minor compared to upstream chemical production impacts.

• Functional unit assumes standard concentration formula providing 20 wash loads per liter bottle, with each wash using approximately 50 grams of product under typical European washing machine conditions.

• Water consumption during manufacturing and raw material production stages are excluded from carbon accounting but represent significant environmental impacts estimated at 5.4 liters per liter of finished product.

• Use phase emissions from water heating during washing cycles contribute substantially to total product lifecycle impact but fall outside the cradle-to-gate CCI scope, varying significantly by regional energy sources and consumer washing temperature preferences.
