Question 1

Which products does PureSurf offer?

Accepted Answer

Three families built on the PureSynth platform: NEXOVANT, a bio-based amine oxide surfactant available as F Pro and F Eco; RHEOSYL, an additive-free gelator and rheology modifier; and SYLVAXIS, a bio-based broad-spectrum antimicrobial active.

Question 2

What is the difference between NEXOVANT F Pro and F Eco?

Accepted Answer

Both grades are drop-in amine oxide replacements with the same core chemistry. F Pro is the performance grade with 14× lower aquatic toxicity than the benchmark, F Eco is optimised for the lowest ecotoxicological profile at 57× lower aquatic toxicity (EC50, Aliivibrio fischeri, ISO 11348-3:2007, 30 min, GLP).

Question 3

Which grades are commercially available today?

Accepted Answer

NEXOVANT is the commercial line and ships in sample and pilot quantities. RHEOSYL and SYLVAXIS are at TRL 4, validated in the laboratory and open for joint formulation trials rather than volume supply.

Question 4

Are your surfactants drop-in replacements?

Accepted Answer

Yes. NEXOVANT is designed to replace conventional amine oxides without process changes. We still recommend a short compatibility and stability screen in your own formulation, and our technical team supports that work.

Question 5

What performance data can you show?

Accepted Answer

NEXOVANT reaches a CMC of 80.7 ppm, up to 10× lower than the benchmark, and up to 8× lower interfacial tension. RHEOSYL builds viscosity up to 7.0×10³ mPa·s without conventional thickeners. Every figure on the site names the method behind it.

Question 6

What does a lower CMC mean for my formulation?

Accepted Answer

The critical micelle concentration is the point at which surfactant molecules start forming micelles and doing cleaning work. A lower CMC means the same effect at a lower dose, which reduces active load per litre of finished product.

Question 7

How is the toxicity advantage measured?

Accepted Answer

Aquatic toxicity is measured as EC50 against Aliivibrio fischeri per ISO 11348-3:2007 over 30 minutes under GLP conditions, and compared against a conventional benchmark amine oxide. Algal toxicity is up to 96 % lower under GLP.

Question 8

What is the PureSynth platform?

Accepted Answer

PureSynth is our modular synthesis platform for building surfactant structures from renewable, lignocellulosic building blocks. More than 175 novel compounds have been screened on it, which is how new grades are developed for specific customer requirements.

Question 9

Are PureSurf surfactants biodegradable?

Accepted Answer

NEXOVANT is readily biodegradable under OECD 301F in a GLP study, which is the classification the EU Detergents Regulation builds on for surfactant biodegradability.

Question 10

Are your products palm free?

Accepted Answer

Yes. Our chemistry is built on European lignocellulosic and renewable building blocks, so there is no palm kernel oil or palm oil derivative in the surfactant backbone and no palm supply chain exposure.

Question 11

What safety and classification data exists?

Accepted Answer

GLP studies show NEXOVANT is non-mutagenic (OECD 471) and not corrosive to skin (OECD 431), with an aquatic classification of Category 2. Full safety data sheets are issued per grade.

Question 12

What is the REACH status?

Accepted Answer

The REACH pathway for EU market entry is in progress. We share the current registration status per grade directly with commercial partners, together with the supporting study references.

Question 13

How do I request a sample?

Accepted Answer

Use the sample request form. Research and development evaluation samples are supplied free of charge together with the technical data sheet, safety data sheet and the relevant GLP study references.

Question 14

What quantities can you supply today?

Accepted Answer

Production has been scaled from laboratory grams to 50 kg per batch in under two years. Sample and pilot quantities are available now; larger volumes are planned per customer against a jointly agreed ramp-up.

Question 15

Do you ship internationally?

Accepted Answer

Yes. Shipments follow the applicable regulations for chemical goods, and customs documentation plus certificates of analysis accompany every international shipment.

Question 16

Which documents do I get with a delivery?

Accepted Answer

Technical data sheet, safety data sheet and a batch certificate of analysis. Additional documentation for your own certification or dossier work can be requested through the contact form.

Question 17

Do you run pilot programmes?

Accepted Answer

Yes. We run structured pilots with FMCG and industrial and institutional formulators under NDA. A pilot typically runs three to six months and includes technical support, performance testing and scale-up planning.

Question 18

Can you develop a custom surfactant?

Accepted Answer

Yes. The PureSynth platform is modular, so structures can be tailored to a defined performance target. Custom development starts with a joint specification workshop under NDA.

Question 19

Who is behind PureSurf and how is it funded?

Accepted Answer

PureSurf FlexCo is a TU Graz spin-off backed by an EIC Transition grant of EUR 2.48M under Horizon Europe (grant agreement 101058142) and aws PreSeed funding.

Question 20

What is your IP position?

Accepted Answer

Four patent families across more than eight jurisdictions, with a freedom to operate position that has been reviewed and is clean for the current portfolio.
