Hypochlorous acid (HOCl) is a powerful yet gentle compound that has been relied upon for over a century for its ability to kill bacteria and promote healing. While it's primarily known for its medical uses and sanitation properties, it's also become a hero ingredient in skincare, especially for those with sensitive skin. Here’s a brief look at the history of HOCl and how it became a staple in both healthcare and skincare.
Early Discoveries: The Birth of Hypochlorous Acid
Hypochlorous acid’s journey begins with the discovery of chlorine in the 18th century. While Swedish chemist Carl Wilhelm Scheele isolated chlorine gas in 1774, HOCl is formed when chlorine dissolves in water. It wasn’t until the 19th century that its powerful disinfecting properties were recognised, especially in medicine.
19th Century: Revolutionising Wound Care
In the 1850s, British surgeon Joseph Lister introduced antiseptics to reduce infections during surgeries, and hypochlorous acid quickly became a trusted tool for sterilising wounds and medical equipment. Its ability to kill harmful pathogens without causing irritation made it an invaluable asset in medical treatments.
20th Century: Sanitation and Industrial Use
By the early 1900s, hypochlorous acid was widely used in water treatment plants and cleaning products. It became essential for sanitising drinking water and preventing waterborne diseases. It also gained a place in hospitals, where it was used to disinfect surgical instruments and hospital environments, ensuring the safety of patients and healthcare workers alike.
Modern Day: A Key Ingredient in Skincare
Today, hypochlorous acid is a star ingredient in skincare, particularly for sensitive skin. Its antimicrobial properties make it ideal for cleansing the skin, while its ability to soothe inflammation and promote healing has made it a go-to for conditions like acne, irritation, and post-procedure care. HOCl cleanses without stripping the skin’s natural oils or disrupting its protective barrier, making it perfect for those with sensitive or reactive skin.
Products like Touchy Skin’s Zero-Touch Cleanse & Soothe Mist harness the power of hypochlorous acid to refresh, hydrate, and calm the skin, offering a gentle yet effective solution for daily skincare routines.
The Future of Hypochlorous Acid
With advancements in production methods, such as electrolysed water technology, hypochlorous acid is becoming more sustainable and accessible. It remains a versatile and eco-friendly option in both medical and skincare applications. Whether used in hospitals, at home, or in skincare products, HOCl continues to be an essential ingredient for clean, calm, and healthy skin.
Hypochlorous acid has evolved from its early medical uses to become a trusted ingredient in modern skincare. With its ability to cleanse, soothe, and heal without causing irritation, HOCl is a gentle but powerful ally in maintaining skin health. Whether you’re dealing with acne, irritation, or just looking for a refreshing mist, HOCl remains a top choice for sensitive skin.
