Saborino to Launch Limited Moisturizing Sheet Mask Featuring Fermented Ethanol Upcycled from Off-Spec Pure Gummy Candy

Fermenstation Co., Ltd., a bio-manufacturing startup aiming to build a society that regenerates and circulates unused resources through proprietary fermentation technology, has collaborated with StylingLife Holdings BCL Company to develop an original ingredient for the sustainable Saborino project “Amasu Kotonaku Itadaki Mask.” As the second product in the series, the company has transformed off-spec Pure Gummy candies from Kanro Inc. into fermented ethanol. The sheet mask containing this original ingredient, “Saborino Morning Sheet High Moisture Type N PG26” (30 sheets / 288 mL, ¥1,540 including tax), will be released in limited quantities on June 2, 2026. The product was commercialized through collaboration among three companies from different industries. Kanro provided off-spec gummies inevitably generated during manufacturing; Fermenstation upcycled them into a cosmetic ingredient using its proprietary fermentation technology; and BCL Company handled the planning, development, manufacturing, and sales of the Saborino cosmetic product using the ingredient. The original ingredient is fermented ethanol made from off-spec Pure Gummy candy. Fermenstation fermented the gummies with yeast under conditions optimized for their characteristics to produce alcohol. Because foaming in the mash affected the efficiency of the distillation process used to increase alcohol concentration, the company improved both the fermentation conditions and production method, ultimately producing fermented ethanol with a purity of over 95%. The ethanol is used as a base ingredient. Fermenstation notes that effectively using unused biomass, including food loss, food manufacturing residues, and surplus agricultural products, is a global challenge for a sustainable future. The company uses advanced fermentation technology involving diverse microorganisms to co-create businesses with partner companies, upcycling byproducts and food residues from food and beverage factories into high-value functional biomaterials. Fermenstation’s purpose is “Fermenting a Renewable Society.” The company develops and manufactures biomaterials derived from food loss, waste, and other unused biomass using its proprietary unused biomass and microorganism database and fermentation upcycling technology. With its own factory in Oshu, Iwate Prefecture, it can handle development through manufacturing in an integrated manner, while using fermentation byproducts as cosmetic ingredients, feed, and fertilizer to build a circular model that minimizes waste. The company is B Corp certified and has been selected by Japan’s Ministry of Economy, Trade and Industry for J-Startup and J-Startup Impact.
