Surfactants
Reinventing how the world takes care of itself
Surfactants are the working molecules behind cleansing, conditioning and foaming. Sironix reimagines them from the ground up—using renewable biomass and furan-based chemistry to create ingredients that outperform conventional options while reducing environmental impact.
- 100% plant-based from agricultural waste
- 52% CO2 reduction vs conventional surfactants
- 500x hard water performance improvement
- Dioxane and sulfate-free
- Superior foaming and mildness
What are surfactants?
Surfactants, short for surface-active ingredients, are the platform molecules used to make valuable consumer products that penetrate surfaces and lift stains and debris. Consisting of a water-soluble head and a water-repellent tail, they act as detergents, wetting agents, emulsifiers and more
What kinds of surfactants does Sironix make?
Sironix makes surfactants from 100% plant-based materials. Our molecules are plant-based furans—unique bio-based monomers that formulators incorporate into their products to replace petroleum-based (and potentially carcinogenic) materials.
What feedstock does Sironix use?
We preferably use plant sources that are non-competitive with the food supply chain and don’t contribute to environmental damage such as deforestation. Examples are soy and algal oil.
Are Sironix's surfactants safe?
Our surfactants do not result in toxic byproducts such as 1,4-dioxane, nor do they require the use of ethylene oxide. This makes it a safe alternative to other commonly used surfactants.

Our process, your success
At Sironix, everything starts with plant-based furans—versatile, non-toxic molecules that undergo a metamorphosis from agricultural waste into core components of high-performing products. By attaching different functional add-ons to these furan building blocks, we create environmentally sustainable surfactants with exceptional properties.
Our process transforms underutilized biomass into ingredients that help formulators deliver cleaner, gentler and more efficient products without compromise.
Harvest & Decomposition
We collect 100% plant-based materials and break them down into usable raw components.
Furan Engineering
Our patented manufacturing process converts those components into furan surfactants with distinct performance profiles.
Product Validation & Launch
We make sure every surfactant performs at its best before powering eco-friendly personal care and cleaning products.
Furasoft for personal care
Furasoft is a next-gen ingredient made from renewable biowaste that integrates seamlessly into personal care products like shampoos, body washes and cleansers. We’ve eliminated the trade-off between performance and sustainability in consumer product formulation!
| Performance Benefits | Sustainability Benefits |
|---|---|
| 40–90% milder on skin | 100% plant-based |
| 30% more foam | Sulfate-free |
| Hard water tolerant | Dioxane-free |
| Excellent rinse off | 65% fewer greenhouse gases |
Eosix for cleaning
Eosix is a plant-based, eco-friendly cleaning ingredient offering attractive performance gains for detergents and similar products without using costly and caustic chemicals. Its uniquely stable properties eliminate the need for additives otherwise used to boost hard water performance. It’s better for the environment and cheaper, all at once!
| Performance Benefits | Sustainability Benefits |
|---|---|
| 500x more stable in hard water | 100% plant-based |
| X% improved stain removal* | Sulfate-free |
| X% longer lasting foam* | Dioxane-free |
Custom engineering
When off-the-shelf ingredients don’t suffice, Sironix collaborates with formulators to design custom furan-derived surfactants and functional compounds. Need a novel emulsifier? A softer-on-skin cleanser? A polymer with targeted stability and true sustainability? We co-create the chemistry that unlocks the performance your product demands.
