“Turnkey” is a word that has been worn smooth by overuse. In private-label manufacturing it is supposed to mean that one supplier takes a brand owner from an idea to pallets on a loading dock, and that the brand owner is not left holding the parts nobody else wanted to own. In practice it often means the filling is handled and everything difficult — the specification, the stability work, the regulatory decision, the documentation an auditor or a retailer will ask for — lands back on the customer at the worst possible moment.
This page is an attempt to be specific instead. It sets out what actually has to happen for a hypochlorous acid product to exist under somebody else’s brand name, who does which part, and the order the decisions have to be taken in. Some of it is unglamorous. All of it is the difference between a product that ships and a project that stalls eighteen months in because nobody decided early enough what the bottle was allowed to say.
About claims on this page
EcoloxTech generators produce a hypochlorous acid solution on site. They are regulated by the EPA as devices, are not registered disinfectants, and we make no efficacy claims for them or for the solution they produce. The only EcoloxTech product that carries disinfection claims is HOCl-AS200 (EPA Reg. No. 101112-1), used according to its accepted label. Research referenced here describes published studies of hypochlorous acid and electrolysed water under their own test conditions; it is not a claim for any product, and it is not a substitute for the testing your own product will need.
The first decision, and it is not the bottle
Almost every white-label conversation starts with the format. What size, what sprayer, what the label looks like. That is the wrong end. The first decision is which regulatory lane the product sits in, because everything downstream — formula, container, testing, artwork, records, what your marketing team may write — is determined by it.
There are three lanes a hypochlorous acid product commonly sits in, and they are not interchangeable.
| Lane | What it is | What it lets you say |
|---|---|---|
| Registered antimicrobial pesticide | A product registered with the EPA under FIFRA. In our case that is HOCl-AS200, EPA Reg. No. 101112-1, which can be distributed under another brand name through supplemental distributor registration. | Exactly the claims on the accepted label, and nothing beyond them. Named organisms, named contact time, named surfaces. |
| Cosmetic / non-regulated topical | A cosmetic under the US Federal Food, Drug, and Cosmetic Act as amended by MoCRA, or a cosmetic product under EU Regulation 1223/2009. Facial mists, toners, lid hygiene, aftercare, pet grooming. | Cosmetic claims: cleansing, soothing, refreshing, conditioning. No antimicrobial claims, no disease claims, no pesticidal claims. |
| Food contact and process water | Use in or on food, or on food-contact surfaces, under the relevant food-additive and food-contact authorities rather than under a disinfectant label. | What the authorisation covers, at the concentration it covers, with any required rinse or drain step. |
The reason this has to come first is that the lanes have different failure modes. In the registered lane, the constraint is that your marketing may not substantially differ from the accepted label — a rule that catches far more brands than the label itself ever does. In the cosmetic lane, the constraint is that the moment you claim the product kills anything, you have stepped out of cosmetics and into either pesticide or drug territory, depending on what you claimed it kills and where. In the food lane, the constraint is concentration and the presence or absence of a rinse.
A brand that decides the lane in month one designs a coherent product. A brand that decides it in month nine has already tooled a bottle, printed artwork and briefed an agency, and discovers that the front panel has to be rewritten.
Why we start at the water and not at the drum
Most private-label chemical manufacturing is a blending operation: buy the actives, buy the base, combine them to a specification, fill. Hypochlorous acid does not work that way, because it is not a stable purchased ingredient in the ordinary sense. It is generated, and what you generate from determines what you end up with.
EcoloxTech builds the generation equipment. That is not a marketing detail — it is the reason the specification conversation can happen at all. When the cell, the control system, the input chemistry and the fill line are in one chain, a change to a set point is a change you can make and verify. When they are spread across three suppliers, a drift in output is a conversation in which everyone points at someone else.
| Input | What we specify | Why it matters downstream |
|---|---|---|
| Water | Double-filtered reverse osmosis and deionised water | Dissolved minerals and organics consume available chlorine before the product ever reaches a customer. Feed water quality is the single largest determinant of how a batch ages. |
| Salt | USP-grade sodium chloride, free of heavy metals | Trace metals catalyse decomposition. Food-grade salt is not the same specification and does not behave the same way over twenty-four months. |
| Acid | Pharmaceutical-grade hydrochloric acid | Used to set pH. Industrial grade carries impurities you do not want in a product that will be sprayed near someone’s eyes. |
| Additives | None by default | No buffers, surfactants, fragrances, preservatives or stabiliser packages unless a specification requires one and it has been tested with the oxidiser rather than alongside it. |
Published work on how these solutions hold their strength over time — the stability of electrolysed oxidising water and stability at low concentrations — is worth reading before you finalise a format, because it explains why two products with the same number on the front panel can behave very differently a year later. It is research, not a product claim, but it is the research your formulation decisions are arguing with.
What you actually specify
A white-label specification for a hypochlorous acid product is shorter than people expect, and every line of it has a consequence.
- Free available chlorine, in ppm. The headline number. It sets what the product can be used for and, in the registered lane, it is fixed by the label rather than by preference.
- pH. Determines the proportion of the available chlorine present as hypochlorous acid rather than hypochlorite ion, and in topical products it also determines how the product feels. Our cosmetic-grade range is 5.0 to 6.5.
- Oxidation-reduction potential. A second, independent measurement of the same solution, which is why it is worth recording. Cosmetic-grade is specified above 800 mV.
- Format and fill volume. Not a packaging question. A trigger spray, a bag-on-valve continuous spray and a single-use sachet are three different stability problems.
- Container and closure materials. Part of the formula, not part of the branding. See below.
- Declared shelf life. Which has to be supported by data on your configuration, because it is going on the artwork.
Formats
These are the formats shown at Cosmoprof 2026 and the ones most often specified. Each has a different filling route and a different stability profile.
| Format | Typical use | The thing to watch |
|---|---|---|
| Box spray / trigger spray | General topical and surface products, retail and professional | Headspace grows as the bottle empties, so late-life performance is a real consideration. |
| Continuous spray (bag-on-valve) | Facial mists, aftercare, anywhere an even fine mist matters | Best barrier against headspace, highest tooling commitment. Decide early. |
| Gel spray | Where dwell on a vertical or awkward surface is wanted | Thickening system has to be compatible with an oxidiser, which rules most of the obvious ones out. |
| Wipes | Travel, professional bags, point of care | Substrate choice dominates everything. Nonwovens vary enormously in how much available chlorine they absorb. |
| Single-use sachets | Sampling, travel retail, clinical kits | Excellent stability, highest per-unit packaging cost, strong sampling economics. |
| Hydrogel | Aftercare, occlusive applications, veterinary | Needs a matrix with no oxidisable polymer backbone. Ours is a stabilised inorganic matrix for exactly that reason. |
| Hand cleanser | Retail and professional personal care | Sits closest to the claims boundary. Be certain what lane you are in before artwork. |
Stability is a packaging decision
The most common misunderstanding in this category is that shelf life is a property of the solution. It is a property of the solution, the container, the closure, the headspace, the fill temperature and the storage conditions, considered together. A specification that is stable in an amber HDPE bottle with a foil induction seal may not be stable in the clear PET the brand team preferred for shelf appeal.
So the sequence is: specify the solution, choose candidate packaging, then test the combination. We hold chlorine retention data out to twenty-four months for the sealed configurations we supply, and offer optional nitrogen-blanket sealing where a format warrants it. If you arrive with tooling already committed, we will test it — but you have removed your own room to manoeuvre, and occasionally the answer is that the component does not work.
The documentation that ships with the product
The paperwork is where turnkey is won or lost, because it is what your customers, your retailers and your auditors will ask for, usually at short notice and usually after the product is already selling.
- Certificate of analysis per batch, with the measured values against the specification.
- Batch and lot traceability back through the fill to the generation run and its inputs.
- Safety data sheet in the format the destination market expects.
- Stability data for the configuration you are actually selling.
- Safety testing appropriate to the lane — for cosmetic-grade solution, human repeat insult patch testing and a formulation developed to be non-cytotoxic.
- Artwork review against the constraints of the lane, before print rather than after.
None of this is optional in the sense that you can skip it. It is only optional in the sense that you can choose to assemble it yourself afterwards, at a worse moment, without the underlying records.
Who does what
| EcoloxTech | You |
|---|---|
| Generation, formulation to specification, filling, sealing, batch records and certificates of analysis | Brand, positioning, the claim you want to make, and the decision on which lane that claim puts you in |
| Compatibility and stability testing on the packaging you propose | Packaging selection, artwork and print, and the commercial relationship with your printer |
| Safety data sheets and the technical file behind the specification | Registrations, listings and notifications in your own name, in the markets you sell into |
| Flagging where a proposed claim falls outside the lane | Your own regulatory counsel. We will tell you what we see; we are not your regulatory adviser and cannot sign off your file |
| Not competing with you in your category, and not reselling your specification | Forecasting, so a generation run is scheduled rather than improvised |
Where these projects actually go wrong
- The claim is written before the lane is chosen. An agency delivers a front panel that says the product kills things, for a product that was scoped as a cosmetic. Everything after that is rework.
- Packaging is tooled before compatibility is tested. Expensive, and the failure is silent — the product looks fine and the available chlorine has quietly gone.
- The declared shelf life is aspirational. Somebody writes twenty-four months on the artwork because a competitor does, without data on their own configuration.
- Research is treated as substantiation. A published study on a hypochlorous acid solution under laboratory conditions is not evidence for your product at your concentration in your bottle. It is context. It is genuinely useful context — and it is not a substitute for testing your product.
- Nobody owns the registrations. In the registered lane, state-level registrations are the brand owner’s obligation, and they take longer than people plan for.
- The first order is the forecast. Generation is scheduled. A brand that treats the first purchase order as both a trial and a peak-season commitment will be disappointed by the lead time.
A realistic sequence
Stated as a sequence rather than a timeline, because the durations depend on the lane and on how quickly decisions come back from your side.
- Lane decision, driven by the claim you want on the front panel.
- Specification agreed: ppm, pH, ORP, format, fill volume, target shelf life.
- Candidate packaging identified and sent for compatibility testing.
- Bench samples, and an honest conversation about how they feel and smell in use.
- Stability programme started on the actual configuration. This is the long pole, and it cannot be compressed by wanting it to be.
- Artwork drafted and reviewed against the lane’s constraints, before print.
- Registrations, listings or notifications in your name, depending on the lane and market.
- First production run, with certificate of analysis and full batch traceability.
Steps five and seven run in parallel with everything else, and they are almost always what sets the date. Brands that start them early ship on time; brands that treat them as the last step do not.
Numbers we deliberately have not put on this page
Minimum order quantities, fill sizes, unit pricing, lead times and tooling costs depend on the format, the regulatory lane and the volume, and quoting a single figure here would be misleading for most of the people reading it. Those come back in writing with the specification. Ask on the quote form and say which lane you are in — registered disinfectant, cosmetic, or not yet decided.
Questions we get asked
Do we have to decide the regulatory lane before you can quote?
Not before we talk, but before anything is made. The lane determines the formula, the container, the artwork, the testing and what you are allowed to say, so a quote written before that decision is a guess. If you are unsure, describe the claim you want to make on the front of the bottle and the lane usually becomes obvious.
Can one product serve both lanes?
No. A registered disinfectant and a cosmetic are different products with different labels, even where the solution inside is chemically similar. Brands that try to run one SKU across both end up with a label that satisfies neither regulator. Two SKUs is the honest answer, and it is usually the cheaper one.
Do you make the generation equipment yourselves?
Yes. That is the reason the specification conversation is possible at all — the cell, the control system and the fill are in the same chain rather than split across three suppliers who each blame the other when a batch drifts.
Will you also sell our formulation to a competitor?
No. We do not compete with conteact customers in their own categories, and we do not take a specification developed with one brand and offer it to the next one through the door.
What shelf life should we plan for?
Plan the artwork around the stability data for your actual format and container, not around a number from a brochure. We have chlorine retention data out to twenty-four months for the sealed configurations we supply, and there is an optional nitrogen blanket at sealing where a format needs it. A spray that is opened daily and a sealed sachet are not the same product from a stability point of view.
Can you fill a container we have already tooled?
Often, but it has to be tested rather than assumed. Hypochlorous acid is sensitive to what it is stored in and to what the closure is made of, and a container that is perfect for a surfactant can quietly consume available chlorine. Send us the component and we will put it through compatibility and stability before anyone commits to tooling.
Where to go next
If your product needs a registered disinfectant claim, the detail is in white-labelling an EPA-registered disinfectant. If it is a cosmetic or personal care product, see white-label HOCl for cosmetics and personal care. The specification behind both is on the white-label page, and the published literature we draw on is indexed in the research library.
