💧 A cleaner mouth. Fresher breath. Happier gums. No sting required.
Hypochlorous Acid (HOCl) helps reduce bacteria—including odor-causing bacteria behind bad breath—to support everyday oral hygiene along the gumline and between teeth. Our oral rinse and mouthwash is formulated at 100 ppm and pH 6.5-7.0. No alcohol. No burn. No added flavors, dyes or preservatives.
Designed for customers who already have a River Refresh mixing bottle. Each refill includes two 16 oz Activation Packets™ to make 32 oz of fresh oral rinse.
Freshly activated—not pre-mixed. Our unique, patent-pending Activation Packet™ system lets you activate fresh HOCl yourself, helping ensure it starts at the intended concentration and pH. When you control freshness, you can trust performance.™ Why freshness matters.

Why River Refresh
Fresh hypochlorous acid, made simple. Made in Texas, USA, River Refresh is a small business built around a better way to use hypochlorous acid—freshly activated, purposefully formulated, and without unnecessary additives.
HOCl is a powerful but sensitive antimicrobial. Heat, light and air reduce its strength—the more exposure, the greater the degradation. Our unique, patent-pending Activation Packet™ system lets you activate fresh HOCl yourself, helping ensure it starts at its intended concentration and pH. When you control freshness, you can trust performance.™
Custom formulation is at the core of every River Refresh product. We tailor concentration and pH to how each product is used across skincare, pet care, oral care and surface cleaning. Each formulation is purpose-built for its intended use.
River—our Italian Spinone dog—inspired our company name and our search for something better, safer and cleaner for our pets, our loved ones and the environments we share.
