Toothpaste (100ml tube)

Material Composition Assumptions

A standard 100ml toothpaste tube consists of a multilayer packaging system combining polyethylene plastic outer layer with aluminum foil barrier layer, totaling approximately 15 grams for the tube itself. The toothpaste formulation contains sorbitol as the primary sweetening agent comprising roughly 70 grams by weight, while glycerin constitutes about 40 grams serving as a humectant. Water content ranges between 20-40 grams depending on formulation, with an assumed 30 grams for this assessment. Abrasive components including calcium carbonate, silica, and dicalcium phosphate make up the remaining 15 grams, providing the cleaning action. The total product weight including packaging reaches approximately 115 grams, with the paste itself accounting for 87% of the mass.

Manufacturing Geography

The majority of global toothpaste production occurs in China, which has emerged as the dominant manufacturing hub for personal care products due to established supply chains for both active ingredients and packaging materials. Chinese manufacturing facilities typically operate on a grid intensity of 555 gCO2e/kWh, reflecting the country’s continued reliance on coal-fired power generation. This relatively high carbon intensity significantly impacts the manufacturing emissions profile, particularly for energy-intensive processes like aluminum foil production and plastic extrusion. The concentration of chemical precursor manufacturing in the same region reduces transportation emissions for raw materials while increasing the overall carbon intensity of production activities.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2e/kWh	38	Baseline
European Union	295 gCO2e/kWh	32	-16%
United States	385 gCO2e/kWh	35	-8%
India	650 gCO2e/kWh	42	+11%
Brazil	245 gCO2e/kWh	30	-21%

Provenance Override Guidance

1. Manufacturing facility energy consumption data with renewable energy certificates or on-site generation documentation to replace grid intensity assumptions.

2. Detailed ingredient sourcing information including transportation distances and production methods for sorbitol, glycerin, and abrasive materials.

3. Packaging material specifications with recycled content percentages and supplier-specific production emissions data for both aluminum and plastic components.

4. Water content optimization data demonstrating reduced formulation percentages that decrease transportation emissions per functional unit.

5. End-of-life program documentation showing participation in specialized recycling initiatives or take-back programs that divert tubes from landfill disposal.

Methodology Notes

• The CCI score represents cradle-to-grave emissions including manufacturing, transportation, use phase, and end-of-life disposal for one 100ml toothpaste tube.

• Scope 3 emissions dominate the profile due to consumer water heating during brushing, which can vary dramatically based on regional energy sources and individual behavior patterns.

• The functional unit assumes standard twice-daily brushing habits with approximately 30 seconds of water running per brushing session.

• Fluoride and other active ingredient production emissions are estimated based on pharmaceutical manufacturing benchmarks due to limited specific data availability.

• Regional variations in waste management infrastructure create significant uncertainty in end-of-life impact calculations, particularly for developing markets.

• Transportation emissions assume average distribution distances but exclude last-mile delivery variations between retail and direct-to-consumer channels.
