Enzyme Oxygen Laundry Booster

Your gym clothes still smell after washing. Your towels stopped absorbing. Your whites are yellowing. Your detergent handles surface soil. This booster handles everything it misses: seven enzyme classes break down stains and odor-causing deposits, oxygen bleach deoderizes and brightens & whitens through real stain oxidation, and a zinc compound neutralizes the odor molecules themselves. One scoop, any detergent, any machine.


  • 7 Enzyme Classes
  • DNase for Persistent Odor
  • Fragrance Free
  • No Optical Brigtheners

THREE SYSTEMS, ONE SCOOP

Your detergent has surfactants that lift surface soil. That’s one cleaning mechanism. This booster adds three more that work simultaneously. 

SYSTEM 1: 7-ENZYME PANEL

Enzymes are biological catalysts. They break specific molecular bonds and keep working throughout the wash cycle rather than being consumed on contact. Most detergents include 1 to 3 enzyme classes, if any. This booster includes seven, each matched to a specific type of soil to fill in cleaning gaps your detergent doesn't cover:

Protease: breaks down protein: blood, grass, body soil, collar grime.

Lipase: dissolves fats: cooking oil, sebum, body oils, pit stains.

Amylase: breaks down starch: food stains, pasta sauce, baby formula.

Cellulase: manages fabric fibers: trims broken microfibrils that make colors look faded, reduces pilling.

Mannanase: dissolves gum-based residues: cosmetics, ice cream, certain food thickeners.

Pectate Lyase: handles fruit and wine pigments: berry stains, red wine, fruit juice.

DNase: breaks down embedded organic deposits: nucleic acid residue trapped deep in fabric fibers that produces persistent odor. This is why gym clothes keep smelling even after multiple washes. Your detergent washes the surface. DNase reaches what surfactants can’t.

You don’t need to diagnose the stain. One scoop covers all seven types of soil. 

SYSTEM 2: OXYGEN BLEACH

Sodium percarbonate dissolves in water and releases hydrogen peroxide gradually throughout the wash. This provides color-safe oxidative bleaching: it breaks down the molecular structures that make stains visible, brightens whites, and revives colors. Unlike chlorine bleach, it doesn’t damage fibers or strip dye.

SYSTEM 3: ZINC-BASED ODOR NEUTRALIZER

Sodium Zinc Polyitaconate is a bio-based zinc compound that chemically captures and neutralizes volatile odor compounds: the ammonia, sulfur, and other molecules you smell. This isn’t fragrance covering up odor. It’s chemistry eliminating the compounds that produce it.

Three independent odor systems in every wash: the enzymes break down the deposits that produce odor, the oxygen bleach destroys odor-causing residue, and the zinc neutralizer captures the smell itself so it rinses away instead of lingering.

WHY IT WORKS ALONGSIDE ANY DETERGENT

Surfactants lift surface soils. But they can’t break down embedded organic matter at the molecular level. That requires enzymes. Most detergents have no enzymes, or only 2 to 3 classes at low concentrations. The booster fills three gaps your detergent almost certainly has: enzyme breadth, oxygen bleach, and targeted odor neutralization.

DETERGENT BOOST
Stained, heavily soiled, or high body-oil loads: kids' clothes, kitchen towels, workout gear.

Add to drum with detergent:

  • 1 scoop standard load
  • 2 scoops large or heavily soiled
  • Any water temperature, normal cycle. Warm or hot improves bleaching performance. Cold recommended for colors and darks.

Enzymes break down body oils, protein soils, and embedded grime that regular washing leaves behind. Light loads with normal soil don't need a booster. Your detergent handles those.

ODOR RESET
Gym clothes, towels, or anything with set-in odors that survive washing.

Soak before washing:

  • 1 scoop per gallon warm water
  • Soak 1 to 3 hours before washing
  • Overnight is fine

Extended soaking gives the enzymes time to break down the embedded residue that causes odors to return after washing.

WHITES RESTORATION
Dingy whites, yellowed collars, grayed towels and linens.

Machine wash:

  • 2 scoops standard load
  • 3 scoops large load
  • Hot water (120 to 140 F)

Deep whitening soak:

  • 2 scoops per gallon hot water
  • 30 minutes to overnight for severe dinginess

Hot water activates sodium percarbonate's full whitening and brightening power. Use with detergent in the washing machine.

DOSING
1 scoop = 10g (2 tsp). Dosing above is for HE machines. Standard top-loaders: add 1 extra scoop per use case.

DO NOT USE ON
Silk, wool, cashmere, or other protein-based fibers. The protease enzyme that breaks down protein stains will also break down protein fibers.

Every ingredient listed. Every one has a job.

Sodium Carbonate (washing soda) Softens water and boosts cleaning power by raising wash water alkalinity. Helps grease and oil-based soils release from fabric. A mineral compound, not a petrochemical. 

Sodium Percarbonate (oxygen bleach) Releases hydrogen peroxide in water for color-safe brightening and whitening. Breaks down stain color at the molecular level without the fiber damage of chlorine bleach. Also deodorizes.  

Sodium Citrate (chelant and pH buffer) Prevents hard water minerals from interfering with cleaning. If you have hard water, this is the ingredient that makes the difference between mediocre and effective.

Sodium Zinc Polyitaconate (zinc-based odor neutralizer) A bio-based
polymeric zinc compound that chemically captures and eliminates volatile odor compounds. Not fragrance. Not masking. The zinc binds to the molecules that cause odor and neutralizes them.

7-Enzyme Blend (Protease, Lipase, Amylase, Cellulase, Mannanase, Pectate Lyase, DNase) Seven enzyme classes, each targeting a different category of soil. Enzymes are biological catalysts produced through fermentation. They break specific molecular bonds and keep working throughout the wash cycle. See How It Works for what each enzyme targets.

Sodium Silicate (machine protection) Forms a thin protective layer on metal and enamel surfaces inside your washing machine, preventing mineral deposits from bonding during the wash cycle. A small amount that does a specific job.

No fillers, no fragrance, no dyes, no optical brighteners, no undisclosed "proprietary blend."

No optical brighteners. Whiteness comes from actual stain oxidation, not UV-reactive dyes that fake it.

No fragrance. When odor is eliminated at the source, there's nothing to mask.

No chlorine bleach. Sodium percarbonate provides color-safe oxidation without fiber damage.

No dyes. The blue speckles in other boosters are cosmetic. They don't clean anything.

No fillers. No sodium chloride, no excess soda ash added for weight. Every ingredient is functional.

No undisclosed ingredients. No "proprietary blend." All ingredients named, all explained in the Ingredients section.

Each targets a different type: proteins, fats, starches, gums, fruit pigments, and embedded odor-causing deposits. That stain that survived three washes? Your detergent didn't have the right enzyme. One scoop covers all of them.

Oxygen bleach handles what enzymes can't

Enzymes break the molecular bonds. Sodium percarbonate oxidizes the color structures that remain. This is why your whites get whiter over time instead of yellowing.

Zinc neutralizer catches what's released

As deposits break down, volatile odor molecules enter the wash water. The zinc compound captures them so they rinse away. Gym clothes stop smelling after one wash instead of three.
