Understanding the d-limonene supply squeeze
d-Limonene demand continues to grow
8
• Projections show a 70% increase in demand from 2011 to 2021
• Cleaning products account for 77% of d-limonene usage

However, d-limonene is a by-product of
orange juice production…
…and orange juice consumer demand continues to decline.
• Now at a 12-year low
• 50% decline in demand
• New drink alternatives have come into the marketplace
• Higher prices for OJ adds to the reduced consumption
10
Worse yet, disease is systematically damaging orange groves
11
• Florida and Brazil orange production accounts for 75-80% of global supply
• Citrus Greening has devastated both mature trees and nursery stocks in Brazil and Florida—and there is no known cure
• Price of orange juice futures are up 43% since Sept 2015
• 2015 orange harvest will be lowest since 1964
• The impact is global with a focus in North America, South America, Europe, and Asia
The d-Limonene squeeze is a long term and growing problem
Addressing the impacton formulators
The formulator thinks about cleaning as an equilibrium
Specialty chemical providers must understand that the formulator is seeking to reduce the time, temperature and physical effort that their customer needs to use to get a job done.

The decision to formulate a cleaner that contains solvent is driven by the difficulty of the task

Elevance Clean™ 1000+ d-Limonene
Elevance Clean™ 1000:Mitigating price and supply volatility of d-limonene
This high-performing, bio-based ester easily formulates with d-limonene in tar/asphalt removal and degreasing products.
• Protects profitability by insulating from supply shortages and price instability
• Boosts product performance while maintaining citrus aesthetic
• Assimilates well in existing d-limonene formulations; similar HLB requirement

Elevance Clean™ 1000: Protecting profitability
18
Elevance technology has the unique ability to upgrade any commodity feedstock to provide Elevance Clean™ 1000 extender. No citrus. No problems.
• Offers flexibility to reduce dependency on single feedstocks (unlike d-limonene) and to manage volatility
• Provides ability to localize feedstocks, shortening supply chains

Elevance Clean™ 1000: Boosting performance
19
Elevance Clean™ 1000 is more effective in the removal of persistent grease than d-limonene. The higher the proportion blended, the better the performance.

Solving the d-limonene supply squeeze, while improving the safety profile of d-limonene-containing formulations.
• Large, secure supply
• Economical versus d-limonene
• Broad applicability to extend d-limonene usage across industrial cleaning applications for greases, asphalt, tar, crude oil, and fats
• Easy to formulate in existing d-limonene based formulations
• Boosts performance when used with d-limonene
• Improved EHS profile for reducing VOC, flammability, skin sensitization, aspiration toxicity
