THE TECHNOLOGY — Tunable Optical Multilayers

The properties of Opal SHIFT come from its structure of alternating ultra-thin layers that form a Bragg reflector. This reflects a specific wavelength of light determined by layer thickness and spacing.

Responsive polymer layers react and change the spacing when a stimulus is applied — shifting the reflected colour.

APPLICATIONS

Opal SHIFT can be engineered to be compatible with virtually any cosmetic formulation: solvent-based, aqueous, powder, and more.

  • Opal SHIFT pigments formulated in standard nail varnish binders. Dramatic colour shift triggered by water, solvents, and diverse cosmetic liquids. Deep, saturated colour across the spectrum.

  • Opal SHIFT pigments for dynamic hair styling. Responsive colour triggered by sprays and styling products, oils, or ambient humidity.

  • Smart foundations, highlighters, blushes, and lip products. Potential for colour adjustment triggered by natural skin sebum, setting sprays, or lip moisture.
