In today’s ever-evolving home care industry, it is imperative to develop a broad selection of fabric care formulations to accommodate unique consumer demands. Consumers desire increasingly eco-friendly products with equal, if not improved, performance capabilities compared to traditional fabric care cleaners, which challenges ingredient producers and formulators to deliver innovative alternatives. Additionally, both liquid and powder detergents provide distinct experiences, and home care formulators must meet and exceed these expectations to remain competitive.

Effective soil release technology requires careful and intentional formulation, and our Repel-O-Tex® Range of detergency boosting polymers contributes to some of the most advanced solutions on the market today.

Solvay’s Repel-O-Tex® Range of specialty performance polymers for laundry facilitate today’s most advanced fabric care formulations. As the market trends toward more sustainable materials, these specialty polymers facilitate several benefits, including an appealing cost-performance balance, innovative performance mechanisms and an assortment of soil release technologies to contribute to a versatile range of detergent solutions. 



Below is a closer look at the most important considerations when choosing from industry-leading soil release polymers.


The Generalist: Repel-O-Tex® SRP6

Repel-O-Tex® SRP6 is a versatile detergent polymer, compatible with all powder formulations. This nonionic polyester is the workhorse of our Repel-O-Tex® Range, as it powerfully boosts soil release technology in the most advanced cleaning formulations, even when used in very small amounts. Compatible with EU Ecolabel for laundry detergents, Repel-O-Tex® SRP 6 is optimal for both synthetics and mixed fabrics and works to effectively release a variety of tough-to-remove stains. This detergency booster polymer provides powder formulations with anti-graying, whitening, soil protection and easy-handling properties, which make it an excellent soil release polymer for a general selection of fabric care solutions. 


The Specialist: Repel-O-Tex® SF2

Repel-O-Tex® SF2 is a premium-grade, high performance polymer for powder detergents that offers best-in-class soil release technology for polyester fabrics, as well as enhanced anti-soil redeposition properties. This anionic polyester is specially formulated for exceptional detergents made to fight the toughest stains from greasy soils, such as dirty motor oil. Additionally, Repel-O-Tex® SF2 continues to combat soils between wash cycles on polyester fabrics and other tough-to-wash, high-quality clothes. Even in very low amounts, Repel-O-Tex® SF2 imparts extremely effective soil release properties, whitening maintenance, anti-graying and soil adhesion protection for easier subsequent washes. 


The Liquid: Repel-O-Tex® Crystal

Repel-O-Tex® Crystal is a high performance soil release polymer for liquid detergents, specially designed to shield garments against daily soils and deep fabric penetration. This nonionic polyester supports the current market shift toward liquid and concentrated fabric care formats, such as pods detergents, as today’s consumers demand easy-to-use solutions that save water and mitigate the possibility of accidental overuse. Repel-O-Tex® Crystal is cold-wash compatible, as it maintains the same high level of performance in temperatures as cold as 20℃. Additionally, this liquid detergent polymer facilitates eco-friendly formulations and washes with less chemicals, as it requires up to 20% less surfactants without sacrificing performance. Repel-O-Tex® Crystal is an anti-graying agent that offers long-lasting protection, moisture management, whiteness maintenance and effective soil release properties for today’s most advanced liquid laundry detergents.
