Shiseido and Spiber Jointly Develop Cosmetic Ingredient Using Protein Fiber and Formulate It into Products

~ Circular material balancing functionality and sustainability ~

Shiseido Company, Limited (“Shiseido”) has jointly developed a cosmetic ingredient by using Brewed Protein™️ fiber, a biodegradable*1 structural protein made from plant-derived biomass, developed by Spiber Inc. (“Spiber”), with the goal of applying them in products. This is the first time that cosmetics containing Spiber’s material have been launched on the market. While taking the environment into consideration, we apply Brewed Protein™️ materials in our products as mascara fiber that creates supple and beautiful eyelashes and will further promote its wider use in our future product development.
Shiseido is promoting the development of circular materials and products that achieve both high functionality and sustainability under the “Premium/Sustainability” approach of its R&D philosophy “DYNAMIC HARMONY” and based on the idea that resonates with the origin of the company name*2.

*1 Biodegradation of raw Brewed Protein™ fiber has been demonstrated in various natural environments including seawater, freshwater, and soil. (Tests in seawater and freshwater were conducted in accordance with ASTM D6691 and ISO 14851, respectively, and seawater tests confirmed more than 70% biodegradation within 30 days.)
*2 A passage from Chinese Yi Jing: “Praise the virtues of the Earth, which nurtures new life and brings forth significant values.”

Joint development of sustainable cosmetic ingredients using Brewed Protein™️ fiber

Brewed Protein™️ fiber*3, developed by Spiber using its proprietary technology, is a structural protein fiber produced via a microbial fermentation process using plant-derived biomass such as sugar cane- and corn-derived sugars as the main raw material. Research has confirmed it to be biodegradable, and it has already been used in numerous clothing and apparel products as a raw material. In this project, we jointly developed a cosmetic ingredient, taking advantage of our strengths in material science, high commitment to quality, and our close attention to users’ preferences. After repeatedly studying the material from various perspectives, such as safety, stability, functionality, and usability as a cosmetic ingredient, we have succeeded in the formulation of Brewed Protein™️ fiber into our mascara while maintaining the properties of the fiber. In December 2021, Spiber announced the registration of Brewed Protein™️ materials as an INCI name, which allows the use of Brewed Protein™️ materials, including fiber, as cosmetic ingredients*4.

Toward compelling circular manufacturing that is friendly to both people and the global environment

In order to realize our corporate mission, “BEAUTY INNOVATIONS FOR A BETTER WORLD”, we have engaged in business activities while showing our respect for people, society, and the global environment, being grounded in ideas that resonate with the origin of the company name. As part of our R&D activities, we actively promote circular manufacturing, including the designing of sustainable containers and packaging with high functionality, the development of naturally-derived, highly-biodegradable raw materials and upcycled raw materials using manufacturing waste, as well as the cultivation of plants that are the source of raw materials.
