L'Oreal Research & Innovation, Morishita Jintan Co., Ltd. and L'Oreal's first successful development of cutting-edge "active delivery capsules" made of useful ingredients for plant-derived cosmetics

 The Japan L'Oreal Research & Innovation Center, the research and development division of the world's largest cosmetics company L'Oreal Group in Japan, uses useful ingredients of cosmetics obtained from plants through joint research with pharmaceutical manufacturing company L'Oréal Co., Ltd. We have succeeded in developing "Active Delivery Capsule". This capsule contains useful ingredients in a high concentration in the capsule membrane, and at the same time, by enclosing various other useful ingredients in the capsule, it is possible to protect them from oxidation and alteration, and to maintain long-term performance and stability. Become. Previously, capsules only contained useful ingredients inside the capsule, but this new capsule is L'Oréal's first seamless capsule in which the useful ingredients of cosmetics themselves are the main constituents of the capsule membrane.

Milotamunus flaberifolia is a plant that lives in southern Africa. In the dry season, it loses water and loses its leaves, leaving it withered for a long time. It is also called a "revival plant" because it revives to its original form. In Africa, it has been used in traditional medicine because of the restoring force of this plant. Nowadays, its resistance to harsh environments is attracting attention, and its interest as a raw material for cosmetics is increasing.

The extract from Milotamunus flaberifolia was encapsulated with agar and sodium alginate using the seamless capsule technology of Morishita Jintan Co., Ltd. The active delivery capsule, which contains a plant extract in the outer membrane, can contain fat-soluble vitamin E and vitamin C derivatives, which are useful ingredients for cosmetics, and ferulic acid, which has high antioxidant capacity but is unstable. It can provide useful ingredients that are completely protected by the outer membrane in a fresh state. Such advanced delivery technology is unprecedented.

By repeating numerous prototypes and thinning the film to the limit, this active delivery capsule can be easily destroyed by the discharge pressure of a finger or a pump of a cosmetic container, improving transparency and improving transparency. It does not cause noodles * on the skin, which is common in cosmetics, and is easier to use.

 Kazuhiko Maruyama, a researcher at the Skin Care Development Institute, L'Oreal Research & Innovation Center, Japan, said, "We considered incorporating useful cosmetic ingredients into capsule membranes in order to concentrate them as much as possible. Thanks to this, not only was it possible to concentrate cosmetic useful ingredients in the capsule membrane for the first time, but also as a cosmetic material in terms of functionality and feel when applied to products by encapsulating other useful ingredients and adjusting the film thickness. We were able to develop a satisfactory capsule. We actually asked Asian women to use the formula containing this capsule, and more than 90% of them appreciate the usability. " 

The active delivery capsule developed this time uses a plant-derived extract, agar, which is a natural ingredient, and sodium alginate, which is a naturally-derived ingredient. Process is used. In addition, the factory that manufactures capsules has acquired ISO14001 and adopted a "cogeneration system" that uses natural gas, which is a clean fuel, to reduce CO2 emissions and consider air pollution. .. Active Delivery Capsules are cosmetic materials that meet L'Oréal's commitment to 2030, L'Oréal for the Future, a sustainability program.

The Loreal Group started research and development in Japan in 1983, and is conducting research from all angles, including not only product development, but also Japanese skin and hair, society / culture, and makeup habits. Japan's Research & Innovation Center incorporates Japan's advanced technology through collaboration with Japanese universities, research institutes, and companies with various technologies to create attractive products for the Japanese, Asian, and global markets. I am. This time, through the first joint research with pharmaceutical manufacturer Morishita Jintan Co., Ltd., we applied seamless capsules used in the pharmaceutical and food fields to cosmetics, and a new active delivery in which the useful ingredients of cosmetics themselves are constituents of capsule membranes. We have succeeded in developing a capsule. Mathieu Cassier, who was in charge of this project, said, "We are pleased to be able to apply the latest active delivery capsule technology to L'Oréal's products through joint research with Morishita Jintan Co., Ltd., a leading pharmaceutical manufacturer in Japan.

This partnership is an important milestone in keeping consumers at the cutting edge of performance, "said the collaboration.

L'Oreal will continue to develop using active delivery capsule technology in collaboration with Morishita Jintan Co., Ltd. We will continue to develop products for consumers' healthier and more beautiful skin through sustainable technological development that takes into consideration the global environment promoted by L'Oréal.

The active delivery capsule developed this time is applied to the L'Oreal Group brand Armani Beauty's "Cremanella Levicentaris Metaconcentrate".
