Field Notes • No. 2 • June 2026

A good month for partnerships

June was mostly a good month for our partnerships. Several of the trials we mentioned last month have started turning into real commitments, and at this stage of the business that is what we most want to see.

Here is what happened.

Out in the market

Our first order, from Oh Lief

Oh Lief has moved from trialling our acidic sophorolipid to placing a formal order. It is the first product order we have had.

They have developed a babycare formulation using our biosurfactant, and they want to take around 36kg of it. That is our whole pilot batch. If it all runs to plan, our biosurfactants should be on South African shelves in a finished Oh Lief product by around Christmas this year.

Homecare with Oh Lief and Tosh Detergents

We have also started working with Oh Lief on the homecare side, developing detergent formulations for Tosh Detergents. Homecare uses much larger volumes than personal care, so if this comes together it could become a much bigger order for us.

Oh Lief handles the formulation, Tosh gives us a route to their customers, and our biosurfactant replaces the synthetic surfactants these products normally rely on. It is still early days, but we are happy with how it has started.

In the field

A letter of intent from RegenZ

RegenZ has given us a letter of intent for 500kg of our AgroSurf biosurfactant. The order depends on our material passing soil microbe testing first, which we are now running with SoilScopes.

The trial is a greenhouse pot trial on cabbage and wheat. It uses seven treatments across seventy pots and runs for about ten to twelve weeks. The main comparison is RegenZ's SeaBrix product made with our biosurfactant instead of its current synthetic wetting agent, tested against the existing formulation, the surfactant on its own, and a synthetic and an organic fertiliser benchmark. Through the trial they measure the soil's microbial life, root and plant growth, and how well water soaks into the soil.

This data matters to us well beyond the single order. If we can show that our biosurfactant replaces a synthetic wetting agent without harming soil life, that is the evidence we need to keep moving further into the agrochemical sector.

We should be clear about one thing. 500kg is more than our pilot can produce. This is the kind of order our 10,000L demonstration facility is being built to fill, and it is a good sign of the demand starting to build behind it.

Early results from the woodchip work

One of our earlier agricultural partners has been testing our biosurfactant as a wetting agent in making fertiliser from woodchips, and the early results are promising. In their process they have seen a 90% reduction in the run-off of liquid during production, which means far more of the product stays in the fertiliser rather than being lost.

We are now working with them to design a full pilot on a cubic metre of woodchips, to see whether that result holds at a larger scale. If it does, it could become another sizeable offtake opportunity for us in the agrochemical sector.

That covers June. A first order, a first letter of intent, and some good early results in the field. Each of these moves us a step closer to the offtake agreements we need to build our demonstration facility.

If you want to talk about any of it, just reply.

Until next month,
