Desired outcome

We are searching for different mechanisms and/or technologies by which colour indication could be possible. During the process of application, the formulation is transferred to skin. The formulation itself may be:

1. Coloured, in which case the colour gradually fades (turns to a lighter shade of the original colour) prompting re-application, due to abrasion or sweat/water, or
2. Coloured formulations turn colourless with time.

Organization from Germany


  • The technology should be incorporated into a cosmetic formulation and therefore should be considered safe for leave-on skin applications.

Discarted solutions

  • The material shouldn´t contain azo dyes, microplastics and/or nanoparticles.
