What it costs to start

Cheap to try and expensive to do properly, with the gap in the packaging and the paperwork.

Equipment is modest

A mixing vessel, an overhead stirrer, two scales, a pH meter, a viscometer or a consistent alternative, and a filling setup.

All of it is a modest outlay and none of it is exotic.

The pH meter is the one to buy properly, because it is the measurement everything else rests on.

Raw materials are cheap and badly sized

The chemistry in a bottle costs very little.

The problem is minimum quantities: chemical distributors sell in drums, and a drum of surfactant is more than a small maker uses in a year.

Specialist repackers solve it at a premium, which is the right trade while a range is settling.

Packaging is the real number

Bottles, triggers, closures, induction liners, labels and cartons, each with a minimum order in the thousands.

The trigger alone frequently costs more than the contents of the bottle.

And this is cash committed before the first sale, against a design you have not yet tested in the market.

Testing and documentation

The line nobody budgets, and in this category it is real.

A challenge test for the preservative system, which a wholesale buyer will eventually ask about.

Container compatibility testing, which is months of shelf time rather than money.

A safety data sheet for each product, if you sell into workplaces.

And a website with ingredient disclosure, which is a compliance requirement rather than a marketing choice.

If the product carries pesticidal claims, add efficacy testing and registration, which is a different order of magnitude entirely.
