Imagine: you have an idea for the perfect cream. You know how it should smell, how it should feel on the skin, and which active ingredients should be at work. But between "I know what I want" and "here is a finished, stable formula" lies a chasm months wide, filled with laboratory iterations, stability tests, pH adjustments, and unexpected ingredient incompatibilities. This is precisely why the cosmetic contract formulation market is growing faster than new indie brands can open. According to Grand View Research, the global cosmetic contract manufacturing market exceeded $28 billion in 2023 — and continues to grow by 6.5% annually.
But "outsourcing a formulation" is not the same as ordering a logo design. There is a chemistry to these relationships, both literally and metaphorically. Let's break down how this industry works, what to look for when choosing a partner, and why even experienced formulators sometimes prefer to work with professional laboratories.
What is contract formulation and how does it differ from contract manufacturing
These two concepts are often confused, although the difference is fundamental. A contract formulator is, in essence, an outsourced cosmetic chemist. They take your concept (or problem) and develop a formula from scratch: selecting emulsifiers, active ingredients, preservatives, and texture enhancers, balancing the pH, and conducting compatibility tests. A contract manufacturer is someone who reproduces an existing formula on an industrial scale.
Many companies combine both functions, which is convenient: development and scaling happen in one place, reducing the risk of "losing" nuances when transferring a formula to a large volume. But this is not always the case — and it is important to understand exactly who you are talking to.
Three models of cooperation
- Full-service formulation — you arrive with a concept and leave with a finished, documented formula. The chemist does everything: from selecting raw materials to the final stability test.
- Formula consultation / troubleshooting — you already have a formula, but something is going wrong. The cream is separating, the preservative isn't working, or the texture is "pilling." The formulator identifies the problem and proposes a solution.
- Scale-up support — your home formula works for 200g, but when moving to 50kg, the emulsion behaves differently. The laboratory helps adapt the process for industrial equipment.

What happens inside: stages of formula development
Behind the fancy word "formulation" lies a rather rigorous iterative process. Here is what it looks like in a real laboratory — without the romance.
Brief and concept
Everything starts with a brief. A good formulator will ask you questions that might seem strange at first: what is the climate of your target audience? What type of packaging is planned — a pump, a tube, or a jar? Will the product be certified as organic? These details directly influence the choice of ingredients. For example, a tube with a narrow neck requires different rheology than a wide-mouth jar. And tribology and gelling agents are a separate science about how a product feels upon application.
Prototype development and testing
The first prototype is almost never the final one. Usually, the cycle looks like this: the formulator makes 3–5 versions with different ratios of key components, you test them and provide feedback, and then the next round of adjustments follows. In parallel, stability tests are launched — at least 4 weeks at 40°C and 75% humidity (accelerated test), plus a freeze-thaw cycling test (usually 3–5 cycles).
This is exactly where surprises emerge. Cocoa butter can show unwanted polymorphism during storage. A peptide can react with metal ions from the water. A preservative can lose activity due to pH. Read more about why stability is not just "it sat there and didn't spoil" in our article on preserving clay masks — the principles are the same as for emulsions.
Documentation and formula handover
The final stage is documentation. A professional formulator provides you not just with a list of ingredients and percentages, but with a complete technological protocol: the order of adding components, temperature regimes, mixing speeds, and critical control points. Without this, reproducing a formula on different equipment is a lottery.
How to choose a formulator: what to look for
The contract formulation market is quite opaque. There is no single registry, no mandatory "cosmetic chemist" certification, and behind a beautiful website, there could be someone with only a single soap-making course. Here are the real selection criteria.
Specialization matters
A formulator who makes shampoos and cleansers based on surfactants is not the same as a specialist in anhydrous systems or sunscreen filters. The chemistry is fundamentally different. Ask directly: what product categories have they developed in the last two years? Is there experience working with the actives that are important for your concept — for example, retinol, acids, or peptides?
Process transparency
A good partner will explain to you why they choose certain ingredients. Not "because that's how it's done," but because Glyceryl Stearate SE at a 3% concentration provides the necessary viscosity for this ratio of oil and water phases. If a formulator cannot or will not explain their decisions, that is a red flag.
An important point: before starting work, an NDA (non-disclosure agreement) must be signed. Serious laboratories treat this as a standard procedure—the confidentiality of your concepts and data is protected just as carefully as any corporate privacy policy. Clarify in advance who owns the rights to the developed cream formula—you or the laboratory.
Portfolio and references
- Ask for examples of completed projects (anonymized, if necessary)
- Check if they have worked with brands of your scale—startups require a different approach than large manufacturers
- Ask about timelines: a realistic development cycle for a basic emulsion is 6–12 weeks, not 2
- Find out what equipment is used for stability testing
- Check if the laboratory has experience with the regulatory requirements of your target market (EU, US, UK—they are all different)
When to formulate yourself and when to outsource
This is a question every formulator asks themselves at a certain stage. And the honest answer is: it depends on your goal.
If you are making cosmetics for yourself, experimenting, and studying chemistry—independent formulation is invaluable. You understand every ingredient, you feel how the texture changes when adding 0.5% xanthan gum versus 1%. This knowledge is impossible to gain just by reading other people's formulas. By the way, we have a separate detailed analysis on how xanthan behaves in comparison to guar gum.
However, if you are building a brand and want to launch a product on the market, outsourcing makes sense under several conditions:
- You do not have time for iterations (every week of development is a delayed launch)
- The formula requires specific expertise that you do not have (for example, working with UV filters or complex peptide complexes)
- You need documentation that complies with the regulatory requirements of a specific market
- Scaling is planned, and you need technical regulations for production
It is important to understand: by outsourcing a formula, you do not lose control over the product—provided the relationship with the partner is properly structured. You remain the author of the concept, you approve every prototype, and you make the final decision on the composition. The formulator is your technical partner, not a replacement for your vision.
How much does it cost: an honest conversation about budget
Pricing in contract formulation is a topic that is usually avoided. But without understanding the order of magnitude of the figures, it is difficult to plan a business.
Cost structure
Formulators usually work according to one of two models — either a fixed fee per project (flat fee) or an hourly rate plus the cost of materials. A flat fee for developing a basic emulsion (moisturizing cream, serum) in small European or American laboratories starts from €1500–3000. Complex systems — sunscreens, products with a high concentration of actives, niche certifications — can cost €5000–15000 and more.
Stability tests, microbiological tests (challenge test for preservatives), dermatological testing, and regulatory documentation are paid for separately. These items can easily double the total development budget — factor them in from the very beginning.
What influences the price
- Complexity of the formula and the number of active ingredients
- The need to work with rare or expensive raw materials
- Speed: rush projects cost more
- Volume of documentation and regulatory support
- Geographical location of the laboratory (the UK and Scandinavia are traditionally more expensive than Eastern Europe or Asia)
Why understanding chemistry is important even when you are not formulating yourself
Here is a paradox that any experienced brand founder will confirm: the better you understand cosmetic chemistry, the more effectively you work with a contract formulator. You ask the right questions. You understand why the proposed preservative — Phenoxyethanol + Ethylhexylglycerin in a 0.9%/0.1% ratio — is a justified choice, and not just a line in a table. You can assess whether the stated concentration of an active peptide is realistic or if it is a marketing "trace amount".
Knowing the basics of pH in cosmetics allows you to immediately specify in your brief that your AHA acid product must work at a pH of 3.5–4.0 — and the formulator will not waste time explaining basic things. Understanding how active ingredients in natural deodorants work helps you set the task competently if you are developing a product in this category.
That is precisely why education in cosmetic chemistry is not an alternative to outsourcing, but a way to enhance it. If you want to understand the basics of formulation and learn to speak the same language as professional chemists, take a look at what the Walker Formulation Academy Club offers: it contains practical materials specifically for those who want to understand, not just do.
Can I protect my formulation when working with a contract laboratory?
Yes, and this is standard practice. Before starting any collaboration, an NDA (non-disclosure agreement) is signed. The issue of intellectual property rights—who owns the developed formula—is specified separately in the contract. In most cases, during commercial development, rights are transferred to the client, but this must be explicitly recorded in the contract rather than left as a verbal agreement. Reputable laboratories also adhere to corporate privacy policies regarding all client data and concepts.
How long does it actually take to develop a formula from scratch?
For a basic emulsion (moisturizing cream, light serum), it takes a minimum of 8–12 weeks at a normal iteration pace. This includes 2–3 rounds of prototyping and an accelerated stability test (4 weeks at 40°C). Complex products—SPF, products with unstable actives, two-phase systems—can take 4–6 months. If you are promised a finished formula in 2 weeks, this is a reason to ask clarifying questions about exactly what is included in that timeframe.
What should I do if my homemade formula doesn't scale up?
This is a very common situation. An emulsion that works perfectly at 200 g in a home mixer may separate during production at 10 kg due to the different shear forces of the equipment, as well as heating and cooling rates. In this case, you need a scale-up consultation, not a complete reformulation. A formulator will adapt the manufacturing process—sometimes it is enough to adjust the order of emulsifier addition or the temperature regime. Our material on stabilizing anhydrous emulsions provides a good understanding of where problems most often arise during scaling.
