The Japanese materials company is putting its solvent research into a moisturising serum sold through its own online shop.
Green Science Alliance has developed a beauty serum based on natural deep eutectic solvents, or NADES. The Kawanishi, Japan-based company announced the product on 28 October 2026 and sells it through its Nano Sakura online shop.
What the solvent does in the serum
A solvent helps ingredients blend into a single formula. Natural deep eutectic solvents are made by combining naturally occurring compounds in a mixture that melts at a lower temperature than its individual components. This can yield a liquid at room temperature.
In this serum, the solvent is part of the finished formula. Green Science Alliance says it selected the mixture to help the serum retain moisture and leave a non-sticky finish.
Why it matters
The choice of solvent can affect how a serum feels on the skin as well as which ingredients can be dissolved in it. Green Science Alliance says it plans to build on the approach with future serums containing active ingredients derived from plants and other biomass.
