What Are Enzymes in Cleaning Products?

What enzymes are in cleaning products — the proteases, lipases, and amylases that target specific residues.

In short

Enzymes in cleaning products are biological catalysts that break down specific residues — proteases target proteins, lipases target oils, amylases target starches. Each is matched to a kind of organic soil.

Key takeaway

Enzymes are matched to the residue — proteases for protein, lipases for oil, amylases for starch.

Enzymes are the active ingredient in a growing class of cleaning products — biological catalysts that break down specific residues. Each type targets a different kind of organic soil.

What causes it

Enzymes are proteins that speed up specific chemical reactions. In cleaning, they’re matched to the residue: proteases break down protein-based deposits (like urine and biological soils), lipases break down oils and fats, amylases break down starches. The enzyme acts on its specific substrate, breaking it into smaller compounds.

Why it persists

The reason enzymes are effective is specificity — a protease only acts on protein, so it goes after the urine residue and leaves the surface alone. The residue is broken into smaller compounds that are easier to remove and less odorous.

What actually helps

  • Match the enzyme to the residue
  • Give it contact time
  • Let the area dry fully
  • For mixed residues, a blend covers more

Frequently asked questions

What are enzymes in cleaning products?

Biological catalysts that break down specific residues — proteases for protein, lipases for oil, amylases for starch.

What does a protease enzyme do?

Breaks down protein-based residue — like urine and biological soils.

Why are enzymes effective cleaners?

They are specific — each enzyme acts on its residue, breaking it into smaller, less odorous compounds.
