Three things we actually do.

A brief starts with a market position and a sensory expectation, not a protection number. Who is the user, how do they apply, what do they hate about sunscreen, what does the pack cost. Those answers determine the emulsion type, the emollient system, and the filter loading long before the first trial.

Development then runs as iterations against that brief. Mineral systems are unforgiving: the point where the filter concentration reaches the protection target is often the point where the texture collapses. Finding the intersection where both hold is the work.

We do not own a factory, and we are not going to claim one. Production runs through contracted manufacturing partners under our process specification, our quality standards and our accountability to you.

What that means practically: we specify the dispersion procedure, the in-process controls and the release criteria, and we hold the production partner to them. The brand relationship, the specification and the responsibility all sit with us, not with a third party you have never met.

A formulation that cannot be filed is a formulation that cannot be sold. Regulatory requirements differ sharply by market — OTC drug classification in the United States, cosmetic registration in China, nano-specific labelling obligations in the European Union — and each has its own documentation chain.

We prepare the material and safety documentation behind your filing, and we work with your regulatory team or consultant on country-specific submissions. We support the filing; the marketing authorisation is held in your name, as it should be.
