Countinue ShoppingCosmetic and pharmaceutical-grade hypochlorous acid held in a stabilised inorganic gel matrix. The same precision-electrolysed HOCl as our Ultra-Pure liquid, formulated to stay where it is applied.
Formulated for stability
Inorganic Gel Matrix • 200–600 ppm • pH 5.0–6.5
No oxidisable polymer backbone to consume the active. Additive-free, HRIPT-passed, supplied in roller, tube and jar formats.*
A liquid runs off the moment it is applied. Holding the same chemistry in place is what turns dose into contact time.
Dwell, Not Drip
A liquid on a vertical or contoured surface runs off in seconds. Antimicrobial contact time depends on how long the active stays in place.
Controlled Placement
Applied to a defined area without aerosol drift or overspray onto surrounding surfaces, materials or people.
Moisture Retention
Hydrogels hold water at the point of application, keeping the treated area moist between applications.
Inorganic Matrix
No oxidisable backbone for the hypochlorous acid to attack, so the chlorine is spent on the application rather than on the gel.
Shelf life is stated as a range because it is set by the combination of pH and free available chlorine within the bands opposite. Store cool, sealed and out of direct light.
Hypochlorous acid is a strong, non-selective oxidant. Most thickeners are organic polymers and HOCl oxidises them, so the chlorine is consumed by the gel itself long before the product reaches the customer. Transition-metal contamination in natural clays catalyses the same decomposition.
Retained activity in storage, by gelling agent — logarithmic scale
Published bars: laboratory measurements at 70 ppm held to a 20 ppm endpoint under refrigeration (Nagamatsu et al., Dental Materials Journal, 2021). EcoloxTech bar: stated unopened shelf life of the finished gel at 200–600 ppm. Not a controlled head-to-head — the chart shows an order of magnitude.
Free chlorine sits in equilibrium between hypochlorous acid and hypochlorite ion, and only the uncharged HOCl passes readily through the bacterial cell wall. The split is set entirely by pH, so two products at an identical ppm can differ by an order of magnitude in effect.
Share of free chlorine present as active HOCl, by pH
Green bars fall inside the EcoloxTech specification window of pH 5.0–6.5, where more than 91% of free chlorine is the active species.
Published comparisons make the point directly: slightly acidic electrolysed water at 0.5 mg/L free chlorine and pH 5.5–5.8 achieved greater than 4.49 log₁₀ reduction of E. coli in one minute, while sodium hypochlorite at the same 0.5 mg/L achieved 1.28 log₁₀ reduction (PeerJ, 2020). Same chlorine dose; the difference is speciation.
Every batch is built from inputs that meet or exceed pharmaceutical standards, using the same precision-controlled electrolysis as our Ultra-Pure liquid.
Double-Filtered RO/DI Water
Ultra-pure water reduces ionic interference and supports product stability.
USP-Grade Sodium Chloride
Heavy-metal-free salt enables clean electrochemical conversion to HOCl.
Pharma-Grade Aqueous HCl
Precisely micro-dosed to hold the cosmetic pH window of 5.0–6.5.
Proprietary Inorganic Matrix
Selected for oxidative stability against hypochlorous acid. Contributes no organic load for the active to consume.
Additive-Free
No fragrances, no surfactants, no chemical stabilisers, no added preservative.
Packaging
Roller, tube and jar formats from 100 ml to 500 ml, with viscosity specified across a 5,000–50,000 cSt range to suit the applicator.
Unopened shelf life is 8 to 12 months. The range is not a hedge — it is set by where a given batch sits within the specification, because both pH and free available chlorine govern how quickly the active decays.
Storage
Cool, sealed, out of direct light. Heat and UV both accelerate loss of available chlorine; refrigeration is not required but extends life.
What Sets the Range
Batches at the upper end of the 200–600 ppm band, and any drift outside pH 5.0–6.5, sit toward the shorter end of the window.
Verification
Where a lot is near end of life, confirm rather than assume. Free available chlorine can be checked with a test paper kit or photometer.
Compatibility
Reducing agents, organic soils and many surfactants consume free chlorine on contact. Confirm compatibility before combining with any other formulation.
Supplied in bulk to formulators and under private label, for uses that sit inside the cosmetic and non-regulated scope set out below.
Cosmetic Formulation
A non-running vehicle for personal-care and post-procedure skin care where a spray is unsuitable.
Contract & Private Label
Bulk supply to formulators, filled to your specification in roller, tube or jar.
Non-Regulated Surfaces
General surface and equipment applications where a gel is preferred to a spray.
Regulatory position
EcoloxTech HOCl Hydrogel is intended for cosmetic and other non-EPA/FDA-regulated uses. It may not be labelled, marketed or sold for pesticidal, sterilisation, or medical purposes.
EPA Reg. No. 101112-1 does not cover this product. That registration is held for HOCL-AS200, a liquid disinfectant for hard, non-porous surfaces. It does not extend to a gel, to a different concentration, or to any topical or personal-care use. No antimicrobial, disinfectant or sanitiser claim may be made for the hydrogel on the strength of it.
Wound care, first aid, and any claim to treat, prevent or mitigate a condition are medical-device or drug claims in the United States and require their own FDA clearance. The published literature referred to on this page describes the behaviour of hypochlorous acid as a chemistry. It is not a claim about this product and must not be presented as one.
*For cosmetic and non-EPA/FDA regulated uses only. Do not market or label for pesticidal, sterilization, or medical claims.
Certificates of analysis, batch data and pricing are issued on request for the fill size and viscosity you need. Evaluation samples are available to formulators.
