What is hypochlorous acid (HOCl)?

Hypochlorous acid is a naturally occurring, broad-spectrum disinfectant produced by white blood cells. It’s effective against bacteria, viruses, and fungi, yet gentle on skin and most surfaces.

Why isn't HOCl more widely known?

HOCl has been used for over 100 years, even in WWI for wounds. However, it hasn't been widely adopted because it is unstable. Other HOCl products and processes can degrade quickly or turn into bleach. They use hypochlorite (bleach), buffers like vinegar, or other additives in their production. This can lead to impure HOCl products that contain bleach or other contaminants. GentleSen hypochlorous acid tablets give you a fresh solution whenever you need it.

How long is the solution effective?

Once dissolved, the solution remains effective when stored in a tightly sealed, opaque container at room temperature, out of direct sunlight. Efficacy decreases after 7 days, so discard, rinse the bottle and replace with a freshly prepared solution.

How do I use the tablets?

Simply use in tablet form or dissolve the tablet into clean water for effective use. Use with spray bottle or soak items. Dissolves in warm water faster (within minutes). For best results, use distilled, filtered, RO or pure water to ensure the highest purity of the solution.

How does GentleSen ensure the safety and effectiveness of its hypochlorous acid products?

At GentleSen, you can be confident that our formulation ensures the ppm and pH levels are carefully controlled. When used as directed, the solutions are well within the optimal range of 60-150 ppm at stable pH. This range is widely regarded for delivering effective antimicrobial benefits without irritating the skin, helping to maintain the skin’s natural barrier and promote healthy skin care. Our products are designed to provide the maximum efficacy of hypochlorous acid while being gentle and safe for everyday use.

Are GentleSen hypochlorous acid tablets laboratory tested?

Yes. Independently tested by authorized third-party labs, each tablet dissolves into an optimal ppm concentration and stable pH level, delivering WHO-highlighted cleaning power that is tough on bacteria yet kind to sensitive skin. Poses minimal risk if accidentally ingested by curious toddlers or pets.

Why does this product feel less drying to my skin than others?

Many products are sold at a single, relatively high ppm (concentration). If you follow our instructions, the resulting formula gives you the optimal ppm and stable pH that you can use in an effective but gentler concentration. That flexibility helps reduce the “tight” or dry feeling some users report with higher-ppm products.

How did you test that Gentlesen tablets work?

We’ve conducted reputable third-party Safety & Effectiveness tests to confirm that each tablet dissolves into an optimal ppm concentration and stable pH level, delivering WHO-highlighted cleaning power that is tough on bacteria yet kind to sensitive skin. Poses minimal risk if accidentally ingested by curious toddlers or pets.

If you have a known chlorine allergy, or autoimmune disease, it is always advisable to test a small area before full application and communicate with your doctor prior to use.

How should I store the tablets?

Keep tablets in a cool, dry place, sealed in their original bottle. Shelf life is 24 months from manufacture.

Are GentleSen tablets safe for food contact?

Yes. Our formula is food-grade safe and pH-balanced, making it safe to rinse fruits, vegetables, and children’s toys.

Does the solution leave any residue or odor?

No. Once dissolved, GentleSen has a mild, chlorine-free scent that dissipates quickly. It breaks down into harmless salt and water, leaving no toxic residues and minimizing environmental impact. Surfaces dry clear and streak-free.

Why Does Hypochlorous Acid Smell Like Bleach?

The smell resembles that of bleach due to the presence of chlorine in both compounds. However, it's crucial to recognize that they are distinct compounds with differing chemical structures. When it comes to cleaning power, hypochlorous acid outshines bleach. It is 80-200 times more effective, without releasing toxic fumes.

Can I travel with them?

Yes. Tablets are non-hazardous solids, TSA-friendly in carry-on baggage. Just declare if questioned.

Can I use hot water?

Yes—up to 40 °C speeds dissolution without degrading HOCl.

Is this safe for use around pets?

We will work quickly to ship your order as soon as possiblYes, when used as directed and allowed to dry completely before pet contact.

e. Once your order has shipped, you will receive an email with further information. Delivery times vary depending on your location.

 Can I store the mixed solution in a spray bottle?

Yes—use an opaque bottle and label with “Use by” date.
