Brief & feasibility
We listen to your idea, frame the concept and confirm technical and regulatory feasibility.

We turn your idea into a complete range: formulation, testing, regulatory work, production and packaging, carried by a single team that knows your project inside out. You keep control of your brand; we bring the laboratory, natural or organic, made in France.

Launching a brand often means juggling providers who never talk to each other: the formulator ignores the regulations, the factory ignores the packaging. We prefer to hold the thread with you, from the first conversation to the delivered products, taking the time to explain every decision.




We take care of the whole chain, or only the steps you need, at your pace and within your budget.




We clarify your concept, your audience, your price positioning and your regulatory constraints.
Our formulators develop exclusive formulas, natural or organic, tested and stabilised.
Mandatory testing, the Product Information File and CPNP notification: your compliance is secured.
Contract manufacturing in France, from small runs to volume, packaging included.
An exclusive formula, created for you.
White labelProven formulas, in your colours.
Either way: compliance, production and delivery by the same team.
We started Costomise to be the laboratory we wish we had found when launching a brand: a single point of contact that tells the truth about lead times and regulations.
We listen to your idea, frame the concept and confirm technical and regulatory feasibility.

We develop the formulas and iterate on samples until you approve the texture.

Stability, packaging compatibility, safety assessment and the Product Information File.

We manufacture your run, fill and pack, control quality and deliver your finished products.


What is the minimum order quantity?
Matched to your stage: we know how to start with small runs.
How long from idea to production?
It depends on the complexity of the range - we tell you at the scoping stage.
What budget should I plan?
Quoted precisely, once your specifications are scoped.
These answers depend on your project: send us your specifications and we will give you a precise quote.
We adapt volumes to your stage of development and are used to supporting small launch runs. The minimum depends on the type of product; we discuss it together during scoping.
It depends on the complexity of the formula and the mandatory regulatory testing. We give you a realistic schedule from the brief onwards, with no promises we cannot keep.
