Is Borax Safe in a Bath?

No, adding borax to a detox bath is not recommended because it can irritate skin and cause poisoning if the bathwater is swallowed.

Is borax safe in a detox bath?

Do not add household borax to a detox bath. There is no established evidence that doing so removes toxins or improves health, and there is no recommended amount that can be relied on as safe for bathing.

An accidental exposure does not necessarily mean serious harm has occurred. The response depends on what happened, including whether someone swallowed the water or got borax in their eyes. Rinse exposed skin and contact poison control for advice if you are unsure about the exposure.

How would borax work in bathwater?

Borax is a boron-containing salt also known as sodium borate. It dissolves in water, but dissolving does not make it harmless or turn bathwater into a detox treatment. Borax can irritate skin and eyes, and swallowing it can cause poisoning.

Exposure is not the same in every situation. The amount involved, length of contact, condition of the skin and whether the water is swallowed all matter. Broken or irritated skin, for example, deserves particular caution; so does any situation in which a child might drink bathwater.

The liver and kidneys do most of the body's detoxification, while the lungs and gut also help eliminate waste. Sweat removes only trace amounts. A bath may be relaxing, but it does not replace these processes or draw toxins out of the body.

What does the evidence say about borax baths?

There is no established clinical evidence that adding borax to bathwater detoxifies the body or provides a health benefit. Claims about a borax bath should not be treated as proof that it is effective or safe.

Information about boron as a nutrient, or about borate compounds used in other settings, does not establish the safety of adding household borax to a bath. A bath product containing an ingredient related to borax is also not the same as adding household borax yourself: products and their formulations differ.

There is no evidence-based bathing dose to recommend. Diluting borax in a large amount of water does not prove that the resulting bath is safe, especially when exposure conditions vary or bathwater could be swallowed.

How can you bathe more safely instead?

Use plain, comfortably warm water rather than adding borax. If you want to use a bath product, choose one intended for bathing and follow its label; stop using it if it causes stinging, itching or a rash. People with sensitive skin may prefer plain water because even products intended for bathing can cause irritation.

For a simple bath:

Fill the tub with comfortably warm water, avoiding water hot enough to make you feel overheated.
Bathe without adding household borax. Keep the water out of your mouth and eyes.
Get out if you feel dizzy, too hot or uncomfortable, and rinse your skin if a product has caused irritation.

Use care getting in and out of the tub, particularly if you have balance problems or feel lightheaded. A bath can be part of a comfortable routine, but it should not be used in place of medical care for symptoms or a diagnosed condition.

Who should be careful, and when should you get help?

Do not use borax in a child's bath, and supervise children around bathwater. People who are pregnant should avoid overheating in a bath and ask their pregnancy care clinician about any bath product they are unsure about. People with eczema, broken skin or other skin irritation should be especially cautious with additives and seek medical advice about persistent symptoms.

If borax or borax bathwater gets on skin, leave the bath, remove contaminated clothing and rinse the skin with running water. If it gets in an eye, begin rinsing the eye with gently running water and contact poison control for instructions. Seek medical advice if irritation is severe or continues after rinsing.

If anyone swallows borax or bathwater containing it, contact poison control promptly rather than waiting for symptoms. Do not make the person vomit; ask poison control before giving anything by mouth. Keep the product container or label available so you can identify what was involved.

In the United States, call Poison Control at 1-800-222-1222. Outside the United States, contact your local poison information service or emergency services. Call emergency services immediately for trouble breathing, a seizure, collapse or difficulty waking the person.
