Shiseido presents Washable Lock Technology, a solution that combines curvature retention and ease of hot-water make-up removal, thus meeting a major technical challenge in the cosmetics sector.
Shiseido has developed an innovative mascara technology, called Washable Lock Technology, which offers good curl retention while allowing easy make-up removal with warm water. This breakthrough is a response to a long-standing technical challenge in the mascara field, challenging the traditional concept of water resistance.
Unique film technology
This technology is based on a new film that combines functions often considered as opposites. « Our aim is to create a film that combines dispersibility in oil-based formulations with washability in hot water. »explains Toshihiko Matsukura of Shiseido's Brand Value R&D Institute. The film consists of an optimized polymer, polyacrylate-51, and has been developed using carefully scrutinized ratios of monomers to achieve physical properties that were previously difficult to balance.
Performance assessment
Experiments have shown that formulations equipped with this technology maintain lash curl equivalent to that of conventional waterproof mascaras. In make-up removal tests with warm water, the film expands and softens, making it easy to remove with just a light rub. These results are promising for the application of this technology to other make-up products.
