We often get asked by potential customers to make their own recipe. We can look at doing this, but we find that in general most of the formulations require some modifications to make them suitable for scaling up.
We can give an assessment of your formulation and whether we think it is feasible to run on our plant. If not, we can suggest changes that we feel have the best chance of working. We would then need to agree a development plan and we can advise you of costs and timescales to run trials.
We are always happy to work with brand owners on development projects, but at the same time if we really think there will be issues with your ideas and the products are not viable we prefer to tell you before you invest time and effort in development costs.
