At Interlac, we divide project management into 6 key stages:
Interlac supports you from concept development through to the delivery of the finished product, with close monitoring at every stage to ensure the success of your projects.
Every project is unique. If you choose our full-service option, we take care of the entire process. We can also adapt to your specific needs and support you with just one or two stages of the project.
Interlac is focused on creating new products, improving performance and finding new applications and formulations. The techniques used are constantly optimized, as are the formulas, which are systematically validated by independent expert laboratories and certified: evaluation for human health, skin tests, tolerance studies and verification of protection indices.
We also take care of the regulatory part; Is your formula found? We take care of the tests and the registration on the dedicated platforms.
Together we will put together your specifications to develop a tailor-made formula that best meets your expectations. The techniques used in our laboratory allow us to offer you a final product that meets your requirements. In order to guarantee you a high-quality formulation, tests are systematically carried out on the stability and compatibility of container and contents.
Our custom contract manufacturing options:
At Interlac, we offer three custom contract manufacturing solutions, combining R&D expertise and regulatory compliance
Choose a formula from our catalogue, ready to use, compliant with quality standards and ideal for a quick product launch.
Customize an existing formula by adjusting elements such as fragrance, active ingredients, colour or texture, to create a product that reflects your brand.
Create a unique product from A to Z. Our R&D team supports you every step of the way: formulation, testing and regulatory compliance.
Does the formula we developed meet your expectations? Or do you simply need regulatory support for one of your projects?
Interlac provides you with its full expertise in preparing the regulatory documentation required to place your product on the market. We also manage the mandatory regulatory tests for tolerance, safety and efficacy, all carried out by independent, certified laboratories.
