Cold Processing Fabric Softeners: Reduce Energy with Rapeseed-Based Esterquat and Simplified Manufacturing

(available in the SOFW media library after the congress)

Lecture Language: English

Consumer expectations in fabric care are evolving toward a dual demand for reduced environmental impact and high sensory performance. But how can formulators deliver on both, without adding complexity or cost? And can manufacturing processes themselves become part of the sustainability solution?
STEPANTEX® RA-80-G is a rapeseed-derived esterquat designed to help address these questions. With its renewable fatty acid origin and high biorenewable carbon index, it supports more sustainable formulations while maintaining competitive softening performance compared to traditional esterquats. In addition, the material is non-flammable and suitable for formulations targeting vegan and Leaping Bunny certifications.
A key benefit lies in its cold-processability. What if fabric softeners could be easily produced at ambient temperature, without heating and cooling steps? This approach simplifies manufacturing, reduces energy consumption, shortens processing time, and can lower associated CO₂ emissions under defined conditions. The product also demonstrates rapid dispersion, stable viscosity, and robustness across temperature variations, supporting more flexible and efficient industrial operations.
Beyond process efficiency, STEPANTEX® RA-80-G enables next-generation formulation concepts. How can formulators transition to concentrated or even waterless formats without compromising performance? And what opportunities exist to reduce transportation footprint while offering more convenient, consumer-friendly dilution solutions? These are key areas where this technology provides new flexibility.
Overall, STEPANTEX® RA-80-G combines high softening performance with reduced process energy requirements and formulation versatility, supporting the development of modern fabric softener systems aligned with evolving market and regulatory expectations.
