Deodorant Spray (aerosol)

Material Composition Assumptions

A typical aerosol deodorant weighs approximately 120 grams and consists of several distinct components. The aluminum alloy can represents the largest single component at roughly 45 grams, accounting for nearly 38% of total weight. The deodorant formula itself, including active ingredients like aluminum chlorohydrate and zinc compounds along with fragrance materials and siloxanes, comprises approximately 50 grams or 42% of the product weight. Hydrocarbon propellants including propane, butane, and isobutane make up around 20 grams or 17% of total mass. The remaining components include the aerosol valve mechanism at roughly 3 grams and a plastic actuator button weighing approximately 2 grams, together representing the final 3% of product weight.

Manufacturing Geography

Primary manufacturing occurs across three major regions, with Germany serving as the reference location due to its significant role in European aerosol production and well-documented grid intensity data. German facilities benefit from an electricity mix averaging 401 grams of carbon dioxide per kilowatt-hour, reflecting the country’s transition toward renewable energy sources while still maintaining industrial manufacturing capabilities. Additional production centers in the United States and China serve regional markets, with transportation costs and local regulatory requirements influencing facility placement. The choice of Germany as the default region reflects both data availability and the prevalence of major personal care manufacturers operating sophisticated aerosol production lines in this location.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
Germany	401 gCO2/kWh	52	Baseline
United States	386 gCO2/kWh	50	-4%
China	555 gCO2/kWh	58	+12%
Poland	659 gCO2/kWh	62	+19%
France	59 gCO2/kWh	41	-21%

Provenance Override Guidance

1. Submit detailed aluminum sourcing documentation showing percentage of recycled content versus virgin aluminum, as recycled material can reduce emissions by up to 58% compared to primary aluminum production.

2. Provide propellant composition analysis specifying exact hydrocarbon blend ratios and sourcing origins, since different propellant formulations have varying carbon intensities during production.

3. Document manufacturing facility energy consumption data including renewable energy percentage and actual grid intensity values for the specific production location and time period.

4. Supply transportation mode and distance information for major component shipments, particularly aluminum can sourcing and finished product distribution patterns.

5. Furnish end-of-life data showing actual recycling rates and waste management practices in target markets, as regional recycling infrastructure significantly affects total lifecycle emissions.

Methodology Notes

• The CCI score represents cradle-to-gate emissions including raw material extraction, manufacturing, and transportation to retail distribution centers but excludes consumer use phase and final disposal.

• Scope 3 dominance reflects the material intensity of aluminum packaging and the upstream emissions associated with propellant production, while direct manufacturing emissions remain relatively modest.

• The functional unit covers one complete aerosol deodorant container as typically purchased by consumers, including all packaging components and propellant charges.

• Volatile organic compound emissions during consumer use are excluded from the carbon footprint calculation as they primarily contribute to local air quality issues rather than climate forcing.

• Data gaps include variability in recycling rates across different markets and the carbon intensity differences between various aluminum alloy formulations used in aerosol can production.

• Transportation emissions assume average distribution distances but may vary significantly based on specific retail channel requirements and regional logistics networks.
