any stage, so the by-products 1-4 dioxane and nitrosamine, both of carcinogenic concern, cannot form. 7 In addition, a third-party conducted a lifecycle assessment( cradle-togate) estimated greenhouse gas emissions 45 – 75 % below conventional petrochemical equivalents across the current product range.
Feedstock optionality matters commercially as well as environmentally. Since the fatty acid furan platform runs interchangeable oil feeds and multiple residue streams can be sourced regionally, Sironix can move away from less-favoured raw ingredients without reformulating and therefore does not depend on a single crop.
Major supply chain restrictions have historic precedent, for example, Indonesia’ s 2022 palm export restriction. They are now commonplace with the volatility in global trade, so flexibility in oil feeds can help alleviate concerns about feedstock availability and price points.
Validation on commercial equipment
Following Sironix’ s strategy of confirming scalable production first, manufacturing capabilities for the process steps outlined in Figure 1 are tied to demonstration at pilot scale on equipment available and currently in use for manufacturing at commercial scale. Two pilot campaigns validated the platform’ s chemistry on installed assets available for commercial-scale manufacturing.
In May 2025, an acylation demonstration with Pressure Chemical generated approximately half a

tonne of fatty acid furan product. This confirmed that the process was scalable and could yield marketquality ingredients.
In November 2025, a sulfonated fatty acid furan was produced on a Ballestra Sulphonext multi-tube falling-film
air-SO 3 reactor( pictured on previous page), the same class of equipment used for conventional anionic surfactant production worldwide. The campaign confirmed reactor compatibility and safe operation, yielding material that hits personal care specifications.
The sulfonated fatty acid furan properties survived the transition to production equipment and the material showed performance comparable to SLES, along with mildness and hardand cold-water tolerance, reproducing the laboratory profile at scale while improving purity and yield.
The path to commercial volumes will inherently provide challenges. However, understanding the supply chain flexibility, equipment compatibility and ingredient quality achievable from scaled manufacturing significantly reduces the odds that fatty acid furans and their derivatives will fall into the same pitfalls suffered by many biobased hero molecules. In addition, aligning with veteran manufacturers proficient with these unit operations allows for a smoother transition to scale.
Letting structure guide application
Scalability guided Sironix’ s initial chemistry selection; the properties of the resulting compounds then determined which applications to pursue. The properties of Furasoft- LFS( Table 1) were measured against commercial benchmarks for anionic surfactants commonly used in personal care and cleaning products. These are properties of the molecules, not the formulated product, so they do not have to be re-established for each application.
These data point to applications beyond personal care. For example, high calcium tolerance may be useful in hard-water cleaning and agricultural systems, while the low Krafft point supports cold-water applications. However, low irritation and surfactant performance strengthened the case for personal care as a beachhead market, where regulatory pressures and commercial economics also proved favourable.
Regulation in personal care continues to evolve as more is learned about environmental and health impacts of common ingredients as well as byproducts in personal care. Of particular note are 1,4-dioxane, a by-product that can be present in ethoxylated ingredients, and nitrosamines, byproducts that can form in alkanolamide ingredients used to boost foam and viscosity in cleansers. Both are listed under California ' s Proposition 65.8, 9
New York’ s limit of 1 ppm on 1,4-dioxane placed more than 1,000 products in scope for reformulation, with further state and federal action signalled. 10 Some formulators are willing to work with ingredients containing 1,4-dioxane as manufacturing improvements in sulfonation and dioxane removal have reduced its concentration, while others are seeing this pressure as an opportunity to adjust ingredient selection. From the perspective of ingredient platform design, the fatty acid furan manufacturing route does not involve the ethoxyation or amine chemistry that forms 1,4-dioxane and nitrosamines.
