Who owns your skincare formula? Ownership, NDAs, exclusivity and switching manufacturers

What you own under each manufacturing model, what an NDA really protects, how to agree exclusivity, what you need in hand to move a product to another factory, and a step-by-step plan to switch without running out of stock.

Not legal adviceThis guide explains common practice and the main legal ideas. Contracts and trade secret law differ by country; have a lawyer review your NDA and manufacturing agreement.

Short answer

Who owns a skincare formula depends on the model and the contract: with OEM you bring your own formula and keep it; with private label from a stock formula the manufacturer owns it and can sell it to others; with ODM (custom development by the manufacturer) ownership is whatever you agree in writing, from exclusive use to a full buy-out. Formulas are protected mainly as trade secrets, so an NDA keeps information confidential but does not by itself give you ownership or exclusivity, and it does not stop someone from developing a similar product independently. If you may switch manufacturers later, agree in advance which of three levels you will receive (the INCI list, the full formula with percentages, or a full technology transfer with process and specifications), and plan 4 to 6 months for the move, including new stability checks and updated regulatory files such as the EU product information file, the US MoCRA listing and the Canadian notification.

Who owns the formula: OEM, ODM, private label

The three manufacturing models are explained in full in OEM vs ODM vs private label. For ownership, the differences are:

Model	Who develops the formula	Who usually owns it	Can others buy the same formula?
OEM (original equipment manufacturing)	You, or your own chemist	You. The manufacturer only produces it.	No, if your contract and NDA say so
ODM (original design manufacturing, custom development)	The manufacturer's chemists, from your brief	Whatever the contract says: exclusive use for you, joint rights, or a buy-out	Depends on the contract
Private label from a ready (stock or library) formula	The manufacturer, before you arrive	The manufacturer. You own your brand, label and packaging design.	Yes, usually
White label	The manufacturer	The manufacturer; often the finished product is identical for every buyer	Yes

Most brands start between the last two: a ready formula adjusted for them (different texture, scent or active level). The adjusted version is new work, so agree whether it stays yours. See also white label vs private label.

What "owning a formula" means

A skincare formula is rarely patented. Most are protected as trade secrets: under the US definition used by the USPTO, information that has value because it is not generally known, and that its owner takes reasonable steps to keep secret. The EU protects trade secrets on similar terms (Directive (EU) 2016/943). As long as the secret is kept, protection has no time limit; once it is public, it is gone.

What is secret and what is not:

Public: the INCI ingredient list, because it is printed on every label. Anyone can read it.
Secret: the exact percentages, the specific raw materials (trade names, grades and suppliers behind each INCI name), the order of addition, temperatures, mixing speeds and times, and the quality specifications. Two products with the same INCI list can feel and perform very differently because of these.
Not covered: your brand name (protected by a trademark; see trademark your brand name), and your label artwork (protected by copyright and your design contract).

Two limits matter. Trade secret laws in the US and the EU treat independent development and reverse engineering (analyzing a product bought on the market) as lawful. So no contract can stop a competitor from making a similar product from your label, and a manufacturer can usually reuse general know-how. What a contract can do is stop the manufacturer from reusing your specific formula.

What an NDA covers, and what it does not

A non-disclosure agreement (NDA) is a contract to keep shared information confidential and to use it only for an agreed purpose. A mutual NDA protects both sides: your brief, plans and prices, and the manufacturer's formulas and processes.

An NDA usually covers	An NDA does not do
Your brief, product plans, target prices, launch dates and customer lists	Transfer ownership of a formula to you
Formula details either side shares (percentages, process)	Give you exclusivity on a formula or a market
Use only for the stated purpose (developing and producing your product)	Stop independent development or analysis of your product once it is on sale
A confidentiality period (often several years, sometimes no end for trade secrets)	Protect information that was already public, such as your INCI list on the label
Return or destruction of documents when the work ends	Replace a manufacturing agreement (price, quality, defects, delivery)

Sign the NDA before you send a detailed brief or ask for formula detail. Read the definitions (what counts as confidential), the purpose, the duration, which law applies and where disputes are heard. The templates page has an NDA explainer, and questions to ask a manufacturer lists what to confirm in writing.

Exclusivity: formula, market and time

Exclusivity is a separate promise from confidentiality. It can be cut three ways, and you can combine them:

Formula exclusivity
The manufacturer will not sell your specific formula, or one made from your brief, to anyone else. This is the most common and the most useful for a brand. Define "your formula" carefully: the exact formula, or anything within a set range of it?
Market or channel exclusivity
The manufacturer will not sell a similar product to another brand in your country or channel (for example Amazon US). Manufacturers agree to this less readily, because it limits their business. Expect minimum purchase commitments in return.
Time
Exclusivity for a set number of years, often renewed if you keep ordering. Time-limited exclusivity is easier to obtain than permanent exclusivity for a stock formula.

What manufacturers usually ask in return: that you place orders regularly, that you pay development fees, and sometimes minimum annual volumes. If you stop ordering for a long time, the exclusivity may lapse. Write all of it down: what is exclusive, where, for how long, under what conditions it ends, and what happens to the formula if it ends.

ExampleA brand selling a 30 mL PDRN serum on Amazon US asks for exclusivity. The contract says: the adjusted formula (same actives, same texture) will not be sold to other brands; the manufacturer may still sell its base library PDRN serum to others; the brand receives the full INCI list after the NDA; and if the brand later moves production, a formula transfer is quoted separately. Everyone knows where the lines are.

Formula transfer and buy-out

A formula transfer (or buy-out) is when the manufacturer hands over enough information for another factory to make the product, usually for a fee. Agree on it before development starts, because it is much harder to negotiate after you depend on one supplier. A full transfer package can include:

The formula with exact percentages of each raw material.
The raw material list with trade names, grades, suppliers and specifications.
The manufacturing process: phases, order of addition, temperatures, mixing and homogenizing conditions, cooling, and in-process checks.
The finished product specification (appearance, pH, viscosity, microbiology limits) and test methods.
Stability and compatibility data, challenge test reports and other test results.
Regulatory documents the manufacturer prepared, if they belong to you under the contract.

Prices for transfers vary widely and depend on how much development work went into the formula; ask for the price in writing. Even a perfect transfer is not plug-and-play: the new factory has different equipment, so the first batches need a side-by-side comparison and a stability check.

What you get when you switch

When you move a product to a new manufacturer, what you can hand over decides how close the new product will be:

What you have	What the new manufacturer can do	Result
INCI list only (and the product itself)	Develop a new formula to match the texture, look and performance, using the INCI list and lab analysis as a guide	A close match, not an identical product. New stability data and a new safety assessment are needed.
Full formula with percentages	Rebuild the formula, choosing equivalent raw materials where the exact ones differ	Very close. Differences come from raw material grades and process. Stability and compatibility should be checked again.
Full technology transfer (formula, raw materials, process, specifications)	Reproduce the product on its own equipment and confirm it against the specification	The closest result. Still run side-by-side samples and a stability check on the first batch.

Most brands that switch only have the INCI list and the product. That is enough to start: a good lab matches a product from a sample and its label, which is a normal service at many Korean manufacturers. See custom skincare formulation.

Regulatory files that follow the formula

Moving a product to a new factory changes some regulatory records, even when the formula stays the same. As of October 2026:

Market	File	What changes when you switch
EU	Product information file (PIF) and cosmetic product safety report (CPSR), kept by the Responsible Person for 10 years after the last batch	The PIF includes a description of the manufacturing method and a statement of GMP compliance, so it must be updated for the new manufacturer. The safety assessor reviews whether the CPSR still holds (new raw material grades bring new impurity profiles).
EU	CPNP notification	Update the notification if its information changes, for example a new formula or a new country of origin.
UK	SCPN notification and UK product information file	Same logic as the EU; your UK Responsible Person updates them. See UK cosmetics regulation.
US	MoCRA product listing and safety substantiation	The listing records the registration number of the facility that makes the product and is updated annually. Change the facility in the listing, and keep safety substantiation for the product as now made. See MoCRA compliance.
Canada	Cosmetic Notification Form	Health Canada requires an amended notification within 10 days after information becomes inaccurate, such as manufacturing details or formulation. See Canada cosmetics regulation.
All markets	Label, barcodes, origin	If the country of manufacture changes, "Made in" changes. A formula change that alters label information may need a new GTIN (see barcodes).

Who holds these files matters. If the manufacturer or its partner prepared and filed them in your company's name, make sure your contract says you receive copies and can transfer them. Regulatory work for each market is covered in FDA, MoCRA and CPNP for Korean skincare.

Switching without a stockout, step by step

The biggest risk in switching is running out of stock while the new product is being developed and approved. Plan backwards from your stock.

Count your runway
Divide units in stock (including stock at your 3PL or Amazon) by average monthly sales. If you have less than about 6 months, order one more batch from the current manufacturer first, or slow promotions. See cash flow, inventory and reorders.
Collect everything you own
INCI list, product specification, COAs, SDS, stability and test reports, safety reports, notifications and listings, label and box artwork files, dielines, barcodes and any formula or process documents in your contract. Ask for missing copies politely and in writing.
Choose the new manufacturer and sign an NDA
Share the brief, the product and the documents under a mutual NDA. Ask how they will match or transfer the product, what it costs, and whether the new version will be exclusive to you.
Match or transfer the formula
With only the INCI list, expect lab samples in a few weeks and one or more revision rounds. With a full transfer, expect a confirmation batch.
Compare side by side
Test the new sample against the current product: texture, scent, color, pH, absorption, skin feel over a week, and how it behaves in your container. Ask a few loyal customers or staff to test blind.
Run stability and compatibility checks
At least an accelerated stability and a compatibility check in the final pack before you commit to a full batch; real-time data continues after launch.
Update regulatory files and labels
PIF and CPSR review in the EU and UK, MoCRA listing in the US, the Canadian notification, and label changes such as country of origin. Have the new label checked before print.
Produce the first batch with overlap
Time the first production so it lands while you still have 1 to 2 months of old stock. Sell old stock first (first in, first out).
Tell your channels
Retailers and marketplaces may need new documents (COA, SDS, listings). If the product changed noticeably, update the listing and tell customers honestly.

2 to 4 weeksFirst lab samples at KoreanOEM, then 10 to 14 days per revision round

4 to 6 weeksProduction after sample approval at KoreanOEM (4 to 5 for a library formula)

4 to 6 monthsA realistic switch from first brief to stock in your warehouse by sea

Common mistakes

Assuming that signing an NDA means you own the formula or have exclusivity.
Paying for custom development without a written line on who owns the result and whether it can be sold to others.
Not asking, before development, what you will receive if you move production later.
Expecting a new factory to make an identical product from the INCI list alone.
Switching manufacturers without updating the EU PIF, the MoCRA listing or the Canadian notification.
Starting the switch with 2 months of stock left, then running out during sample revisions.
Letting the manufacturer file registrations in its own name with no right for you to receive or transfer them.
Asking for exclusivity on a stock formula without offering volume or time commitments, then being refused.

Frequently asked questions

Who owns a private label skincare formula?

With a ready (stock) formula, the manufacturer owns it and can usually sell it to other brands, while you own your brand name, label and packaging design. With a custom formula, ownership is whatever your contract says, so put it in writing before development starts.

Does an NDA mean I own the formula?

No. An NDA keeps shared information confidential and limits how it is used, but it does not transfer ownership or give exclusivity. Ownership and exclusivity need their own clauses in the manufacturing or development agreement.

Can a skincare formula be patented?

Sometimes, if it is truly new and inventive, but most skincare formulas are protected as trade secrets instead. A trade secret lasts as long as it stays secret, while the INCI list printed on the label is always public.

Can my manufacturer sell my formula to another brand?

If it is a stock or library formula, usually yes. If it was developed for you, it should not, but only a written clause makes that certain; at KoreanOEM a custom formula developed for a brand is not offered to other brands.

What do I need to move my product to a new manufacturer?

At minimum the product and its INCI list, plus your specifications, COAs, test reports and artwork files. With only the INCI list the new lab makes a close match rather than an identical copy, so plan for new samples, stability checks and updated regulatory files.

Do I need new registrations if I change manufacturers?

You usually update rather than restart: in the EU the PIF must describe the new manufacturing and GMP status and the safety assessor reviews the CPSR, in the US the MoCRA listing names the new facility, and in Canada the notification must be amended within 10 days of information becoming inaccurate.

How long does it take to switch skincare manufacturers?

Plan about 4 to 6 months from first brief to new stock in your warehouse by sea, covering samples and revisions, stability checks, production, QC and shipping. Start with at least 6 months of stock or place a bridging order with your current supplier.

When do I get the full ingredient list from KoreanOEM?

After the NDA is signed. You can sign a mutual NDA online in your My page, and the full INCI list is then shared for your labels and registrations.
