ActiveEnzyme: The Formula's Working Mechanism

PawFresh's ActiveEnzyme formula works by digesting organic residue — the enzyme blend, delivery, and what it treats. The product mechanism explained.

In short

ActiveEnzyme is PawFresh's enzyme-blend formula — protease, lipase, and supporting enzymes that digest the organic residue carrying pet odor. It removes the source material rather than masking it, delivered via spray or the NanoMist fogger.

Key takeaway

ActiveEnzyme digests the residue — a protease-lipase blend breaking down the organic material that holds pet odor.

PawFresh’s ActiveEnzyme is the formula behind the products — an enzyme blend designed to digest the organic residue that carries pet odor. Understanding what it is and how it works clarifies what the products can and cannot do.

What ActiveEnzyme is

ActiveEnzyme is PawFresh’s proprietary enzyme-blend formulation — a combination of enzyme classes selected for pet-residue substrates. The blend is designed to address the mixed organic deposits pet odor lives in: proteins, lipids, and associated compounds.

It is a formula, not a single enzyme — a blend tuned for the pet-odor substrate.

The enzyme coverage

The blend centers on protease (for the protein fraction — urine proteins, saliva, skin residue) and lipase (for the lipid fraction — sebum, oils, greasy deposits), with supporting enzymes for the associated organic material.

The coverage maps to the pet-residue composition — protein and lipid are the dominant fractions.

The blend mirrors the mess — protease for the protein, lipase for the oils, supporting enzymes for the rest.

How it removes odor

The mechanism is digestion — the enzymes cleave the residue’s organic molecules into smaller, soluble fragments that are removed rather than left to emit. The odor compounds’ substrate is consumed; the emission source is eliminated.

This is removal, not masking — the smelly material is broken down, not covered.

What it treats

  • Urine residue — the protein and organic fraction
  • Skin-oil deposits — the sebum film
  • Saliva and dander residue — the protein coating
  • Fecal residue — organic material
  • General pet organic deposits

The delivery formats

ActiveEnzyme is delivered two ways — the spray format for concentrated deposits (saturation treatment) and the NanoMist fogger for distributed environmental coverage. The same formula, different delivery for different jobs.

The safety profile

Enzyme-based treatment is pet-safe in the relevant sense — the enzymes digest organic residue; they are not oxidizers or harsh solvents. Normal precautions apply (keep pets off treated areas until dry, avoid direct contact), but the mechanism is the gentler one.

What it does not do

ActiveEnzyme does not mask — there is no heavy fragrance cover-up. It does not oxidize — no bleaching chemistry. And it needs the standard enzymatic conditions — dwell time, moisture, reaching the deposit.

Where PawFresh fits

ActiveEnzyme is the formula in every PawFresh treatment product — the enzyme blend doing the digestion.

Frequently asked questions

What is ActiveEnzyme?

PawFresh's enzyme-blend formula — protease, lipase, and supporting enzymes that digest pet-odor residue.

How does ActiveEnzyme remove odor?

By digestion — the enzymes break the residue's organic molecules into removable fragments, eliminating the emission source.

Is it a masking product?

No — it removes residue rather than covering it. There is no heavy fragrance masking.

What does it work on?

Pet organic residue — urine, skin oils, saliva, dander, fecal deposits. The protein and lipid fractions.
