Q & A

Usage Instructions

What kind of bathing tablet is HOT TAB?
When you dissolve the HOT TAB tablet in water, it first releases fine carbon dioxide gas.
This carbon dioxide gas, which creates an acidic pH in the water, is immediately neutralized and transforms into bicarbonate ions and hydrogen ions, resulting in water with a neutral pH.
The water is characterized by its gentle, soft texture, without any fragrance or color.
For the best experience, immerse yourself in warm water at or below 106℉ for about 15 minutes to fully experience the effects of Hot Tab.
How do you use HOT TAB?

The Hot Tab series can be used not only for bathing but also for washing your face, hair,
and in the shower (as a bath cosmetic). It is a unique tablet-form bath additive that focuses on the benefits of baking soda and citric acid. For a standard household bath (about 160 liters),
dissolve 3 tablets of the medicinal HOT TAB for your bath. For the premium series of bath cosmetics, use 3 tablets, and for the Sparkling Hot Tab, use 5 tablets. For foot baths or face washing, dissolve 1 tablet in a large basin.
Is there a recommended bathing method?
We recommend soaking in a bath with the dissolved tablet (bicarbonate ions) at a temperature of 106℉ or below for at least 15 minutes. This bathing method is called the "Bicarbonate Bathing Method.“ When the bath is 108℉ or higher, the sympathetic nervous system is stimulated, causing muscle tension and blood vessel constriction. Conversely, at 106℉ or below,
the parasympathetic nervous system is stimulated, which relaxes muscle tension and dilates blood vessels. This gentle warming promotes blood circulation and raises body temperature, helping to condition the body without causing damage. For summer, a temperature of 93-100℉ is recommended, while in winter, 98-106℉ is ideal.
Is the recommended 15-30 minutes of bathing the total time spent in the bath, or can it include breaks?
You can either stay immersed continuously or take breaks; aim for a total soaking time of at least 15 minutes. Whether you choose a full-body bath, a half-body bath, or a foot bath, the goal is to relax and rejuvenate your body.
Is it okay to use soap and body wash while using HOT TAB?
While it's perfectly fine to use soap, it's not necessary. Soaps and detergents can strip away the skin’s natural moisturizing layer (sebum and intercellular lipids), which may cause skin irritation. Many users report that even after bathing in HOT TAB water for more than 15 minutes, their skin feels "non-tight" and "moisturized."
Does dead skin remain even if I wash with soap every day?
Yes. The HOT TAB series effectively removes unnecessary dead skin cells. Skin turnover, also known as cell turnover, typically occurs around every 30 days, though this can vary by individual and body part. If turnover is slow, dead skin can cause dullness, making it important to care for dead skin to maintain normal turnover.
Why does the scalp and hair feel smoother after using HOT TAB?
HOT TAB’s cleansing effect removes stubborn silicone and mineral sebum dirt from hair roots and surface dirt from hair. It gently cleanses without damaging the skin barrier or the scalp and hair, preserving moisture. This results in a smooth texture as the surface tissues are aligned with negative ions.
Does bathing in yesterday's dirty water mean bathing in a "dirty bath"?
When first using HOT TAB, the water will get dirty as old skin cells and mineral sebum dirt are removed. In households with many members, the bath may get quite dirty initially,
but after a few days to a week, this will no longer happen. Assess the water’s cleanliness to decide if it’s suitable for the next day’s bath.
What is mineral sebum dirt?
Hair is known as an excretory organ for minerals. The cause of body and hair odor is that minerals excreted from hair and body hair mix with sebum, which oxidizes and produces an odor.
This mineral sebum dirt is difficult to remove, but HOT TAB cleanses it from the roots.
I usually use bicarbonate baths and feel well-heated, but my atopic dermatitis causes intense itching after bathing in colder weather. Can I use HOT TAB with other moisturizing bath additives for atopic dermatitis?
Generally, avoid using other bath additives, as they are acidic. The HOT TAB series is a unique bath additive focusing on "baking soda" and "citric acid," making the bathwater neutral.
The active ingredient, baking soda, enhances the warming effect and promotes blood circulation while heating the body. Bathing at a low temperature of 98.6°F to 105.8°F is suitable for those with sensitive or dry skin. The bathwater, with dissolved additives,
becomes neutral and gentle on the skin.
Why shouldn't I use commercial bath additives with HOT TAB? Is it okay to use handmade bath additives with 100% natural essential oils and natural salts?
Generally, avoid using other bath additives as they are acidic. Colors and scents can impact immunity,
so limit aromatics to natural ones. While handmade bath additives with 100% natural essential oils and natural salts might seem beneficial and potentially provide relaxation benefits, it's essential to ensure they are compatible with the neutral pH and ingredients of HOT TAB to avoid adverse reactions.
Should I use a shower instead if I usually bathe in 109.4°F water for less than 5 minutes?
Bathing at temperatures above 107.6°F (42°C) can stress the body and does not provide adequate warming or relaxation in a short time. Instead of a shower, it is recommended to enjoy a "bicarbonate bath" by soaking in lukewarm water below 105.8°F (41°C) with dissolved bicarbonate ions for more than 15 minutes for a gentle and relaxing experience.
If someone feels too hot to sleep after bathing, will a shorter bath still be effective?
Instead of shortening the bath time, it is recommended to try soaking in lukewarm water around 98.6°F (37°C) for over 15 minutes, known as a tepid bath or "sensory-neutral bath." Additionally, it is more effective to finish bathing about an hour before going to bed.
How to use HOT TAB in the shower?
To use HOT TAB in the shower, you can use our dedicated showerheads (Bicarbonate Ion Shower or Sparkling Shower). Place one tablet in the tablet holder and use it with a water flow of about 8 liters per minute. Pour the water over your head until the tablet is fully dissolved. The recommended water temperature is between 100.4°F and 105.8°F (38°C and 41°C). Use one tablet per shower session, as it continues todissolve even when the water is turned off. If you have a screw-type commercial showerhead, you can place one tablet inside, though it may dissolve faster than in the dedicated showerhead.
What is the weight of the dedicated showerheads (specifically for cosmetics)?
The weight provided is for the showerhead itself; the actual weight will be heavier when filled with water. The "Bicarbonate Bio Sparkling Shower" weighs approximately 165 grams, and the "Crystal Ion Shower" weighs about 164 grams. When used with the tablet, it neutralizes chlorine and gently cares for your skin and hair.
What to do if the dedicated showerhead becomes difficult to open?
The black rubber in the opening and closing section might be causing resistance. Applying conditioner to the rubber can improve its lubrication, making it easier to open and close. Avoid forcing it open when it is still stiff to prevent damage. Regular application of conditioner should help maintain smooth operation.
Is it necessary to rinse off with a regular shower after bathing or using the dedicated HOT TAB shower?
No, it is not necessary to rinse off. Leaving the HOT TAB solution on your skin and hair will help keep them moisturized. You will experience shiny and firm hair and moisturized skin even without using soap.
The recommendation is to bathe for more than 15 minutes. Does this refer to total immersion time if I get in and out, or continuous bathing time?
Either is fine. The recommendation is for a total immersion time of 15 minutes or more, whether you stay in continuously or get in and out. This applies to both full-body and half-body baths.
Do I need to add a tablet each time I use the reheating function?
If you have a reheating function, the effectiveness will remain the same the next day, so you do not need to add a tablet each time. When first using HOT TAB, or in households with many members, the water may become quite dirty initially. However, after a few days to a week, the water will no longer get dirty. Assess the water's cleanliness to decide if it’s suitable for the next day's bath.
Can leftover tablets from the shower be dried and used the next day?
No, each tablet is intended for single use.
How long does one tablet last in the dedicated showerhead?
Depending on the product, your household water pressure, and temperature, it lasts approximately 6 to 10 minutes. This may vary slightly based on usage. (Note: This is for bath cosmetics.)
you can use the HOT TAB at cooler temperatures, closer to room temperature. However, it may take a bit longer to dissolve completely.
How should I rinse my hair after dyeing it at home?
After coloring, you should rinse out the dye with shampoo. Before and after this process, it is recommended to take a shower with the bicarbonate bath solution.

About storage, and other uses

Can I use the bathwater for washing pets?
Yes, you can use the leftover bathwater to wash pets. If using fresh water for pet washing, fill a container like a basin with about 40 liters of lukewarm water (slightly cooler than what humans would use) and dissolve one HOT TAB tablet in it. This will result in a great condition for your pet’s coat. For daily care, soak a towel in HOT TAB water, wring it out, and use it to wipe down your pet. This helps maintain a shiny and well-kept coat. There is also a "Grooming Tab" specifically for dogs.
Is it safe if my dog drinks water with HOT TAB dissolved in it?
It is not a problem if your dog drinks water with HOT TAB dissolved in it. However, ensure that the dog does not accidentally ingest an undissolved tablet. Please store the tablets in a safe place.
Are there any special storage instructions after opening the package?
HOT TAB tablets should be kept away from high temperatures and humidity. After opening the package, make sure to close the zip tightly and store the tablets in a cool, dry place.

Questions about Bicarbonate

What is the difference between regular hot water and carbonated baths?
A carbonated bath refers to water that has dissolved carbon dioxide gas (CO2).
What is the difference between carbon dioxide gas and bicarbonate ions? Does HOT TAB have a sufficient concentration of carbon dioxide gas?
HOT TAB contains very little carbon dioxide gas. The carbon dioxide gas that is generated quickly transforms into bicarbonate ions in the water. Unlike carbonated baths, HOT TAB is not acidic but has a neutral pH, similar to blood. More important than the concentration of carbon dioxide gas is the presence of bicarbonate ions, which dissolve easily in water.
Doesn't the carbon dioxide gas escape into the air like in carbonated drinks?
Carbon dioxide gas can dissolve in water at a rate of 1.05 grams per liter (1050 ppm). However, even if it dissolves, it escapes into the air within about 10 minutes, similar to carbonated beverages. Commercial acidic carbonated bath additives lose their effectiveness once the bubbles disappear.

Impact on Equipment

Will it damage the bathtub?
There is no effect that will damage the bathtub. This product does not contain sulfur that could harm the bathtub or the hot water system. However, please check the instruction manual of your bathtub and hot water system before use.
Surface of the Bathtub
For use in marble or artificial marble bathtubs, please consult with the bathtub manufacturer.
Can it be used with fully automatic water heaters, EcoCute, 24-hour baths, etc.?
This product is neutral and does not contain sulfur that could damage the bathtub or hot water system. Since its release, there have been no complaints or accidents. However, we cannot verify the condition of individual household equipment, so we do not guarantee the safety of hot water systems. Please use it at your own risk and consult the manufacturer if necessary.
The bathtub manufacturer said salt is not allowed. Does this product contain salt?
This product does not contain common salt (NaCl, sodium chloride) used daily.
The water seems to turn blue on the second day.
This phenomenon occurs when copper ions from the pipes chemically react with fatty acids found in soap or body oils, causing the water to turn blue. It is harmless to the body, but if it concerns you, please change the water daily.
Can HOT TAB be used in a hinoki (cypress) bath? The hinoki bath manufacturer’s website advises against using bath additives with fragrance.
We recommend following the instructions of the bathtub manufacturer for hinoki baths. However, our product can be used without any issues. One feature of hinoki baths is their unique scent. Bath additives with fragrance are not recommended by hinoki bathtub manufacturers because they can affect the natural aroma of the wood. Our bath additives do not contain fragrances, so this does not apply.

About Ingredients

What is polyethylene glycol? Is it a surfactant?
Polyethylene glycol (PEG) can be used in the production of surfactants, but it is not a surfactant itself. Polyethylene glycol 6000 (PEG6000) is a necessary minor ingredient for forming tablets. It is a neutral polymer compound with a long history of use in many commercial bath additives.
Many bath additives sting if they get in your eyes and require thorough rinsing. Is HOT TAB safe in this regard?
HOT TAB makes the bathwater neutral pH, so it is safe even if poured over your head. It has passed ocular irritation tests (alternative methods), so there is no problem.
Many bath additives have scents and colors for relaxation. Why does HOT TAB remain colorless and odorless?
Scents preferred by adults can be overstimulating for babies and young children, and synthetic coloring agents can irritate the skin. HOT TAB is free from such additives, making it a safe choice for bathing with babies, which is why it is well-received by users.
What is the expiration date for HOT TAB?
Although some products may have a specified expiration date, HOT TAB remains stable for five years if unopened, so it does not have an expiration date listed. However, once opened, please use it as soon as possible.

Other Concerns

Are there any individuals who should not use HOT TAB, especially considering many of our elderly customers have health issues?
Individuals who have been advised by a physician not to bathe should not use HOT TAB. For elderly individuals, it is essential to consult their physician to ensure that using HOT TAB will not pose any health risks. Additionally, it is recommended for everyone, including healthy individuals, to avoid high-temperature baths. Always use HOT TAB in water temperatures below 105.8°F (41°C).
Does crushing HOT TAB into smaller pieces affect its effectiveness?
Crushing HOT TAB tablets will reduce their effectiveness. The tablets are designed to be very hard, which allows for the gradual release of micro-carbon dioxide gas bubbles that convert into bicarbonate ions, ensuring the active ingredients dissolve properly in the water.
Can HOT TAB be used for dogs and cats?
Yes, the "Grooming Tab" is specifically designed for dogs and cats, which have more delicate skin with a weak alkaline pH and about one-third the thickness of human skin. Use it at a slightly lower temperature, between 95°F and 100.4°F (35°C to 38°C). You can use it for a pour-over bath for about 10 minutes or for wiping with a lightly wrung-out towel. Using a showerhead can help cleanse the dirt from pores that cause odors and maintain a shiny coat.
Is it safe if my dog drinks water with HOT TAB dissolved in it?
Yes, it is safe if your dog drinks water with HOT TAB dissolved in it. However, ensure that they do not accidentally ingest an undissolved tablet. Store the tablets in a safe place to prevent this.
