MiraChlor-W™ Wound Cleanser Solution FDA 510(k) CLEARED · K252023
MiraChlor™ by LETUS
Pharmaceutical-grade HOCl · Made in USA

Unleash the body's innate defense against infection.

MiraChlor-W™ delivers hypochlorous acid (HOCl) — the same molecule your neutrophils release to fight infection — in its purest, single-species form. It cleanses, supports debridement, and disrupts biofilm without harming the tissue you need to heal.

01 / Mechanism of action

Not a foreign chemical — the same molecule your body makes to heal.

HOCl is endogenous. White blood cells produce it during the first wave of the immune response. MiraChlor-W delivers it pharmaceutical-grade and pH-tuned, so it works with your healing chemistry instead of against it.

i.

Selective oxidative kill

HOCl oxidizes proteins in microbial cell walls. Human cells — with thicker membranes and antioxidant defenses — are spared at the working concentration.

ii.

Biofilm disruption

Penetrates and physically disrupts the extracellular matrix where bacteria shelter — a key barrier to closure in chronic and infected wounds.

iii.

Cleanses & debrides

Loosens slough, necrotic debris, and microorganisms from the wound bed during irrigation and dressing changes, preparing tissue for granulation.

iv.

Preserves healing tissue

At a skin-friendly pH, fibroblasts keep migrating and granulation tissue keeps forming — moisture balance is maintained, odor is reduced.

02 / The competitive edge

Most "HOCl" is a cocktail. Ours is a single molecule.

Many hypochlorous solutions carry a mix of chlorine species left over from manufacturing — hypochlorite, free chlorine, chlorate, chloramines. MiraChlor-W is made with LETUS's patented electrolytic process to yield pharmaceutical-grade HOCl, the active species, essentially on its own.

Typical HOCl solution

A mixture of chlorine species

HOCl OCl⁻ hypochlorite Cl₂ free chlorine ClO₃⁻ chlorate chloramines

Off-target species add cytotoxic load, drift in pH, and shorten potency — without adding antimicrobial benefit.

MiraChlor-W

Single-species, pharmaceutical-grade HOCl

HOCl — the active molecule

No residual sodium hypochlorite, chlorate, or chloramines. Purity is what lets the same molecule be both maximally biocidal and gentle on tissue.

US 11,225,723 B2

Patented production process. MiraChlor-W's HOCl is produced by the LETUS electrolytic method — saltwater electrolysis buffered with sodium bicarbonate — granted by the USPTO. The patent is the engine behind the purity.

03 / Biocompatibility

Tested the way medical devices are —
and it passed clean.

MiraChlor-W's safety profile is backed by a full panel of GLP biocompatibility studies conducted to ISO 10993 and US FDA standards. Across cells, skin, and whole-body endpoints, the findings were favorable.

ISO 10993-5

Cytotoxicity

✓ Non-cytotoxic

At working dilutions on L929 fibroblasts, cell viability stayed above the 70% acceptance threshold — no cytotoxic effect.

ISO 10993-11

Acute systemic toxicity

✓ No toxicity

No mortality, abnormal clinical signs, body-weight changes, or gross pathology following intravenous administration.

ISO 10993-23

Irritation

✓ Non-irritant

Intracutaneous reactivity testing showed no erythema or oedema at injection sites and no adverse clinical signs.

ISO 10993-10

Skin sensitization

✓ Non-sensitizing

Guinea-pig maximization testing produced no delayed (Type IV) hypersensitivity response to the undiluted solution.

ISO 10993-11

Material-mediated pyrogenicity

✓ Non-pyrogenic

Temperature rise stayed below 0.5 °C after intravenous administration — classified non-pyrogenic.

510(k) · K252023

FDA cleared

Reviewed by the FDA General & Plastic Surgery panel and found substantially equivalent for its labeled wound-management indications.

GLP studies conducted by an OECD-GLP / ISO 9001 accredited laboratory to ISO 10993 and US FDA guidelines, 2024. Reports on file with LETUS Corporation.

05 / Two formulations

One molecule. Two ways to put it to work.

The same pure HOCl, formulated and labeled for two settings — everyday care at home, and professional wound management in the clinic.
