Protease is being studied for protein-heavy food soils like egg, dairy, and meat. It will only belong in a saleable formula if the supplier paperwork, dust controls, dose, and finished-product testing all check out.

Commercial enzyme washing product precedent.

Identity
Protease is an enzyme that breaks proteins into smaller pieces. Detergent-grade protease means a protease preparation designed for cleaning products, ideally with a granular or low-dust format, known activity units, carrier disclosure, and supplier safety data.
This is different from a food enzyme or supplement powder. A cleaning enzyme has its own questions: pH, wash temperature, stability, dose, dust behavior, carrier material, and compatibility with the rest of the formula.
Formula Role
Protease is a candidate for protein-heavy food soils. Egg, milk, meat residue, and some cooked-on food films can include proteins. A protease may help weaken those soils so the rest of the wash system can remove them.
The useful question is simple: does this specific protease help remove egg, dairy, meat, and cooked-on food films under real dishwasher conditions?
Protease does not replace the mineral base. It is a specialty ingredient that only makes sense if it works at the finished powder dose and can be handled safely.
Why Old Chemistry Uses It
Old Chemistry is interested in detergent grade protease because protein soils are a real dishwashing problem. If the right enzyme works in the finished formula, it may help the rest of the wash system remove egg, dairy, meat, and some cooked on food films.
The honest version is simple: enzyme cleaning has old roots, but modern detergent proteases are modern supplier materials. We can respect the history without pretending this ingredient is unchanged from 1914, and we will not sell the performance story before the testing is done.
Ingredient Age Note
The 1914 date is a commercial enzyme washing product precedent. It is a historical enzyme-washing reference, not a claim that this exact modern protease was invented in 1914.
The human story starts outside the laundry aisle. Otto Rohm worked on leather, where hides had to be softened after liming. Older bating methods could use fermented animal dung because the useful work was partly enzymatic. Rohm's Oropon gave tanners a cleaner technical substitute, and it put enzymes into factory work before they became a detergent talking point.
Rohm was not selling a modern dishwasher enzyme. He was showing that enzymes could be controlled technical tools. The 1914 washing precedent belongs to that older world of enzyme washing products and brands such as BURNUS. Modern detergent proteases are standardized supplier materials with measured activity, carriers, coatings, and safety paperwork.
There is an honest gap between the old date and the modern ingredient. Industry sources place broad introduction of enzymes into detergent washing powders in the mid 1960s. That does not erase the 1914 precedent. It keeps the story clean: early enzyme washing came first, modern household enzyme detergent systems came later.
Supplier Grade Preference
We want a 50 to 100 g dry granular or low-dust sample with SDS, TDS, carrier or coating disclosure, activity units, recommended dose range, particle or dust information, and lot traceability.
The safety history matters too. Enzymes are proteins, and dry enzyme dust can sensitize workers who breathe enough of it often enough. Granulated, coated, or low-dust enzyme is not just a purchasing preference. It is part of making the work humane and repeatable.
Safety Note
Dry enzyme dust can be a respiratory sensitizer. Treat it with respect: containment, P100 respirator setup when handling dry concentrate, careful cleanup, and written handling controls. Small dose does not mean casual handling.
Claim Caveat
This ingredient is not approved for sale until supplier documentation, safe handling, dose testing, label language, and finished-product testing are complete. We will not claim enzyme cleaning performance until the finished dishwasher powder proves it.
