Is this safe for adults to use Hypochlorous Acid?

YES - Generally Safe
Danger Score: 1 (Lower is safer)
Quick Answer: Hypochlorous Acid is generally considered safe for adults when used in topical products. Adults generally have higher tolerance.

ℹ️General Overview

For adults, hypochlorous acid in properly made skin products is usually safe. Most people can use it on normal skin without problems, but there are some reports that it can irritate the eyes, nose, or lungs if breathed in or that poorly made products can contain unwanted chlorine by-products.

What to Do

Use products as directed and from a reputable brand. Avoid spraying directly toward your face or breathing in sprays. Do not apply to large open deep wounds unless a health professional tells you to. Store products tightly closed and away from heat and children.

⚠️Warnings

Stop use and see a doctor if you get stinging, redness, blistering, trouble breathing, or other strong reactions. Some studies and regulatory reviews have flagged contamination with chlorine-related by-products (for example sodium hypochlorite, chlorine, chloroform) and limited evidence of irritation or effects on the lungs or heart at higher exposures (sources: Environment Canada, U.S. National Library of Medicine, U.S. FDA). If you have a history of respiratory problems or chemical sensitivities, be extra cautious with sprays and mists.

Safety Risk Labels

This ingredient has the following documented risks:

Organ Risk: A government review lists this chemical as likely to be toxic or harmful to organs and a medium human-health priority. Health literature also notes limited evidence of effects on the heart, blood and lungs, so repeated or high exposures could harm internal organs.
Immune system: Animal studies show breathing and allergy effects at low doses, indicating it can affect immune or allergic responses in the airways.
Asthma: A published animal study reported irritant-induced asthma from hypochlorite, showing it can damage the airway barrier and make breathing problems worse.
Long-Term Risk: Laboratory research found this chemical produces excess reactive oxygen species that can disturb cell signals, cause mutations, and lead to cell death — changes that raise concern for longer-term health effects like cardiovascular disease.
Environmental: A government assessment flags this as a suspected environmental toxin and there are contamination concerns because it can be linked with harmful byproducts such as chlorine, chloroform and carbon tetrachloride.
