À propos de cet ingrédient
Deep ocean water sourced 300–600 m below the surface off Cape Muroto in Kōchi. Stable temperature, mineral balance (Mg-rich), and low bacterial load make it a high-grade ingredient for cosmetic moisturisers, mineral beverage, and salt production. Kōchi Prefecture's Muroto and Aki facilities are the largest commercial deep-sea-water sources in Japan; Toyama Bay and Okinawa Kume Island also produce. Branded retail mineral waters and cosmetic moisturising lines have built a multi-decade premium category around the Muroto label specifically.
