Elevance Clean™ 1000The Advantage of d-Limonene Independence
9
Elevance Clean™ 1000 is a high-performing, bio-based ester that easily formulates with d-limonene to mitigate price stability and security of supply problems in tar/asphalt removal and degreasing products.
Protects profitability by insulating from supply shortages
Protects profitability by insulating from d-limonene price instability
Boosts product performance while maintaining citrus aesthetic
Assimilates well in existing dL formulations; similar HLB requirement.
