Enzymes are useful cleaning ingredients, but they are easy to talk about badly.
Some detergent labels make them sound like magic. Some natural-cleaning conversations make them sound scary. Neither version is good enough for Old Chemistry.
An enzyme is not fairy dust. It is not a vague promise that dishes will come out perfect. It is also not something we treat casually just because the amount is small.
If an enzyme belongs in our dishwasher powder, it has to earn its place.
First, we test the powder without enzymes
The base of a dishwasher powder still matters most.
Washing soda, baking soda, citric acid, and the rest of the mineral formula do the broad cleaning work. They help shift water conditions, loosen food soil, and support the wash cycle.
Before we give an enzyme credit for anything, we need to know what the base powder does on its own. That is why a no-enzyme control matters.
A no-enzyme batch answers a simple question:
What can the old mineral chemistry do by itself?
If the base formula cannot stand up on its own, enzymes should not be used to hide that. If the base formula performs well, enzymes can be evaluated more honestly as a small, targeted improvement.
Then we test protease
Protease is usually the first enzyme worth testing in a dishwasher powder.
Its job is protein soil. Think egg, milk, cheese, yogurt, meat residue, and some of the films that dry hard on plates and utensils.
That does not mean protease removes every protein stain in every dishwasher. Real dishwashing depends on water, cycle, dose, temperature, loading, storage, and the rest of the formula.
But protease has a clear job, and that is what we like about it. It is not a vague “enzyme blend” claim. It is a specific tool for a specific kind of mess.
For Old Chemistry, protease is the first enzyme question:
Does a small amount of documented, low-dust protease make the powder meaningfully better than the no-enzyme control?
If yes, it may deserve a place. If no, it does not.
Then we test amylase
Amylase is the second enzyme worth testing.
Its job is starch soil. Think rice, pasta, oatmeal, potato, and starchy sauces.
Starch can be sneaky in a dishwasher. It can leave haze, film, or a pasty residue when the wash is not handling it well. Amylase may help with that kind of residue.
But again, the question is not whether amylase sounds useful. The question is whether it improves the actual formula.
That means testing it against the base powder and against protease-only batches. If amylase helps, good. If it does not, we do not need to add it for the sake of a longer ingredient story.
Why we are cautious with blends
A broad enzyme blend can be tempting. It may include protease, amylase, lipase, cellulase, or other enzymes in one ingredient.
That can be useful in some detergents, but it also makes the product harder to explain and harder to document.
Old Chemistry does not want a mystery enzyme cocktail. We want to know what each ingredient does and why it is there.
A blend only makes sense if three things are true:
- It performs better than the simpler protease or protease-plus-amylase route.
- The supplier documentation is clear enough to support responsible use.
- The carrier, coating, stabilizer, dust guidance, and label implications fit the product.
If those things are not true, a simpler enzyme system is better.
The form matters too
The word “enzyme” is not enough.
A loose fine enzyme powder and a low-dust detergent granule are not the same practical ingredient.
Fine enzyme dust can be a respiratory sensitization concern if inhaled. That is why we care about physical form, not just the enzyme name. A granulated or coated enzyme may sound more modern, but it can be the more responsible choice if it reduces dust and improves handling.
That does not make the risk disappear. It means the ingredient has been designed for detergent handling instead of treated like a casual kitchen powder.
This is one reason we ask suppliers for more than a sales page. We want SDS and technical data sheets. We want activity units. We want recommended use levels. We want storage guidance. We want to know the carrier, coating, and dust precautions.
A small ingredient can still deserve serious paperwork.
What we will not claim
We will not say enzymes are magic.
We will not say enzyme-containing powder is harmless.
We will not call a modern coated enzyme granule ancient kitchen chemistry.
We will not claim “non-toxic,” “hypoallergenic,” “safe for sensitive lungs,” or “safe for kids and pets.” Dishwasher detergent is a concentrated cleaning product. It should be kept away from children and pets, kept out of the eyes, and handled without breathing dust.
We will not make performance claims until we have testing to support them.
What we are trying to build
The goal is not the longest ingredient list. The goal is a dishwasher powder that is understandable, effective, and honest.
That means starting with the mineral base.
Then testing protease for protein soils.
Then testing amylase for starch soils.
Then comparing any blend against the simpler route.
And before anything goes into a sellable batch, checking the documentation, handling requirements, dose, label language, and batch records.
That is slower than fairy dust marketing.
Good.
Old Chemistry should be plain enough to explain.
