Nexdot gives the cosmetics and fragrance industries the means to move towards “Clean Beauty” thanks to a major innovation in UV filtering
23 October 2024
Nexdot, a company specializing in Quantum-dots applications (Nobel Prize in Chemistry 2023), continues to innovate for the perfume and cosmetics industry. Faced with the challenge of reducing the use of additives in the world of perfumery and cosmetics, Nexdot has focused on the development of a new varnish to treat bottles for perfect protection of containers against UV rays. In this context, Nexdot is proud to announce the successful industrial implementation test of its Uvltimate varnish on an industrial production line. The test was carried out on September 19, 2024 at a major glassmaker, which manufactures bottles for the world’s leading perfume and luxury goods companies.
A world first: a transparent varnish to filter UV rays and reduce the use of additives in formulations
Capitalizing on over 10 years’ research into quantum dots, Nexdot designs innovative varnishes incorporating nano-crystals that absorb ultra-violet rays (A, B and C), without any impact on the visible light spectrum. Treated bottles therefore remain perfectly transparent, with no dominant color. The most important molecules used by perfumers and cosmetics manufacturers, especially those of natural origin, are rapidly degraded when exposed to ultraviolet radiation. Without protection, a perfume, for example, would lose its color following prolonged exposure to sunlight, and its olfactory signature would be altered. Formulators are therefore obliged to incorporate additives into their product formulas to protect and stabilize fragile active molecules.
Although organic anti-UV varnishes are already applied to certain bottles to reduce exposure to ultra-violet rays, their effectiveness is not sufficient to enable a significant reduction in the use of additives in formulations.
Nexdot varnishes, which filter UV rays using mineral particles, represent a major advance in this field. Their absorbency can be custom-tuned to be total over the entire UV spectrum, with a very steep cut-off slope that avoids overflow into blue light.
Applied to the outside of perfume bottles, for example, without contact with the contents, they are non-toxic, environmentally friendly, and their perfect transparency means that bottles can be recycled without any impact on the industrial chain.
A major step towards “Clean Beauty”
With over 1,500 vials processed by the production line, the test demonstrated Nexdot’s ability to offer this revolutionary solution for protecting formulations against UV radiation on a very large scale.
The effectiveness of Nexdot varnishes, far superior to all existing solutions, will enable formulators to reduce or eliminate the use of additives designed to protect UV-sensitive molecules (odor, color, active ingredients) in their products, and thus take an important step towards “clean beauty”.
About Nexdot
Nexdot was founded in 2010 on the initiative of Maurice Guillou (ex DGA of Spie batignolles) and Benoit Dubertret (Director of Research at CNRS), to develop industrial applications in France based on the results of Dubertret’s fundamental research into Quantum-dots, or quantum-boxes. In 14 years, Nexdot, whose laboratory and pilot lines are based in Romainville, has filed over 40 patent families, and successfully explored several fields of application for these nanocrystals.
