CBD Bath Bombs and Salts Buyer’s Guide

The fizzy and vibrant bath bombs make a relaxing hot bath a luxurious experience. You can add a lot more to this experience with the use of enhanced CBD bath bombs and salts.

Unless you have been living with your head under a rock, you have heard of CBD and its potential health benefits.

This guide will walk you through the basics about CBD, CBD products including CBD bath bombs, and their potential health benefits.

Let’s get to it.

CBD, THC, and Range of CBD Products

Cannabinoids are the main bioactive chemicals found in the hemp plant. The major cannabinoids include CBD and THC.

The ‘high’ feeling associated with the use of cannabis products is due to its THC content. CBD does not exert such effects on your brain (1, 2).

Instead, CBD interacts with a system in your body called the endocannabinoid system. This interaction is responsible for a variety of health benefits. These include neuroprotective effects, cardiovascular benefits, pain relief, and anti-anxiety properties. In addition, CBD improves immune health and has anti-inflammatory and antioxidant properties (1, 2).

CBD is available in a variety of products. These include oral sprays, tablets, capsules, tinctures, oils, balms, vapes, essential oils, and so on.

Essentials About CBD Bath Bombs

You might not know but CBD is also available in the form of bath bombs and salts. These bath bombs and salts are infused with CBD essential oils.

One of the concepts underlying CBD bath bombs and salts is that of aromatherapy.

Aromatherapy techniques include inhaling the fumes and scents given off by essential oils. This practice is associated with improved psychological, and physical well being. These benefits include the alleviation of pain and improvement in depression and anxiety symptoms (3, 4).

Also, since you will soak in a bath infused with CBD, the essential oils will come into contact with your skin. This will give you the benefits associated with the topical application of CBD in a more relaxing way.

CBD is a lipophilic material as it dissolves in oils. This property allows CBD to cross the skin quite easily. When you take CBD orally it is absorbed from your gut and gets metabolized into your liver. This is referred to as first pass effect. When you apply CBD topically, it enters directly into your bloodstream and avoids metabolism inside your liver (12).

When compared to other methods of administration, topical, mucosal, and intranasal administration of cannabinoids have been proven to be superior as these methods lead to greater plasma levels of cannabinoids. The first pass effect is entirely eliminated with topical administration of CBD(13).

All you need to do is to put a CBD bath bomb into a hot water tub and voila! That’s it.

Infuse yourself while engaging in a glittery, fun, and relaxing experience that will make you come back for more.

While buying CBD bath bombs, you might also come across terms such as CBD isolate, full spectrum, and broad spectrum.

What are these terms and how are they relevant to CBD bath bombs?

In a nutshell, the different terms explain the type of processing CBD undergoes before it reaches your shelf.

Here is a quick table comparing all of the different formulations of CBD (5).

CBD Isolate CBD Full Spectrum CBD Broad Spectrum
Preparation Method The oil is processed and this form contains CBD only. This form undergoes minimal processing and contains CBD, natural terpenes, other cannabinoids, and traces of THC. This form uses a blend of full spectrum and CBD isolate. So this form is high in CBD content but contains no THC.
Best for

Does not contain any THC.

Best for people who want to achieve higher CBD blood levels.

Best for people who want to consume CBD in ihs purest and want to have the added benefits of other bioactive compounds as well. Best for people who want to use the purest form of CBD but want to exclude THC.
Pros Delivers a very high dose of CBD. Comes with the added benefits of additional bioactive compounds. Also, CBD prevents the negative effects of THC. This is referred to as entourage effect. Gives the added benefits of using the plant in its most natural form but is free of THC as well.
Cons Does not come with the added benefits of using the whole plant.

Contains THC so it might have some psychoactive effects. The possibility is low as the quantity of THC is less than 0.3%.

May have a strong natural odor.

May have a strong natural odor.

In the context of CBD bath bombs, the bombs using full spectrum or broad- pectrum CBD are better as they deliver the added benefits of other bioactive compounds along with CBD.

Yes, they are.

CBD is legal in most of the states. This follows from the passage of the 2018 Farm Bill that legalized hemp and any form of CBD product not obtained from cannabis (10).

However, products including bath bombs, should not contain more than 0.3 percent THC, as per the U.S. federal law (11).

Are There Any Benefits of Using CBD Bath Bombs?

Why use CBD bath bombs? Why not use topical or other preparations of CBD?

Here are the reasons to utilize CBD bath bombs.

# 1: CBD Bomb Ingredients Give Added Benefits

CBD bath bombs usually contain additional ingredients like Epsom salt, citric acid, and baking soda.

Epsom salt and baking soda have been historically used for drawing toxins out of the body. They also work to relieve muscle aches and might improve mood as well (6).

# 2: You Might Get the Health Benefits of CBD

Our understanding of CBD is evolving and we are still learning new things about it.

We don’t have a lot of clinical trials to support the use of CBD as an agent for aromatherapy .

We can only speculate based upon existing research. The use of CBD based products trans-dermally or by inhalation may have led to health benefits.

These benefits might include (7, 8):

  • Reduction in pain
  • Decrease in inflammation
  • Alleviation of depression and anxiety
  • Control of neurological symptoms like tremors and seizures
  • Better overall well-being
  • Improvement of skin and hair health

# 3: Other Benefits and Some Warning Points

Since you would be adding a bath bomb to a hot bath, you would get the added benefits of a hot bath massage. It can help you relax tense muscles and relieve your stress and anxiety.

Before you step into a hot bath, make sure you understand what goes into the product you are using.

Make sure your product is free of:

  • Mold
  • Talc
  • Chemicals (Tip: if your product lists an ingredient that you are not sure about, it is highly likely it is an unwanted chemical)

Are CBD Bath Bombs Better Alternatives to CBD Topical Products?

One reason to choose CBD bath bombs over simple topical application is based upon the chance of better penetration of the bioactive substances through the skin when using a bath bomb formulation.

Here is what that means.

Your skin hoards a lot of allergens, dry and dead skin, wastes, and unwanted oils. A warm and soothing bath helps clear all of that off (9). This improves your skin’s ability to absorb the bioactive compounds.

There is a downside to that too.

When you use CBD topical gel or cream, they deliver a high concentration of CBD and other bioactive compounds to a targeted area. When using a CBD bath bomb, the ingredients will get diluted and might not reach the target area in the required amounts.

We have been through the basics. Now, let’s explore a little more about CBD bath bombs.

Working Out the Dosage

You can get CBD bath bombs in a variety of dosages. The dose ranges between 50mg and 250 mg per bomb. You might also find products with higher or lower quantities of CBD per bomb.

What that means is that your hot bath will be infused with 50 to 250 mg of CBD through the use of a single bath bomb.

Now, which concentration to select?

As a rule of thumb, it is always a good idea to start with a lower dosage and then ascend the ladder.

You can start with 50 or 100 mg CBD bath bombs. If you don’t observe an obvious relief in your symptoms, whether that be anxiety, irritated skin or generalized body aches, you can then increase the dose.

You should observe caution when using CBD bath bombs with higher dosages, especially those containing full or broad spectrum CBD as it might lead to irritation of your skin.

Also, please make sure you consult with your healthcare provider before using any CBD based products. Be more vigilant about using CBD bath bombs if you are suffering from a skin allergy.

Smells – Do You Have Any Options?

It depends.

You can use products without added scent. In that case, you should expect a light and soothing herbal aroma.

If you want to spark things a bit more, you can use CBD products with added scents.

That’s where you have a whole range of options to choose from. You can choose lavender, rosemary, jasmine, and so forth.

Are There THC Bath Bombs As well?

It is not legal to sell pure THC based products, including bath bombs.

The U.S Federal law prohibits the use of products in any form that contain more than 0.3 percent THC (11).

Pricing – Comparing CBD Bath Bombs to Other CBD Products of Similar Dose

For all of the CBD based products, pricing depends on factors like:

  • Strength– The cost increases with the quantity of CBD.
  • Extraction Method– Products produced with CBD obtained using the CO2 extraction method cost more.
  • Hemp Source – Hemp sourced from organic, non-GMO, non-pesticide and authorized vendors is used in formulating higher end products.
  • Third Party Testing– Brands that are third party tested will cost more.

Here is a table comparing the cost of different CBD products.

CBD Oil On average, a quality CBD oil costs between $0.10 and $0.17 per mg on an average. An average for a 300 mg tincture/oil bottle may $30 to $120.
CBD Capsules/Tablets It costs an average $0.09 to $0.13 per mg. A 30 tablet pack (15 mg per capsule/tablet) costs between $45 and $60.
Vape Oil Vape oils usually contain higher CBD concentrations and are generally more expensive. A 300mg e-liquid might cost $60.
Topical These generally cost less between $0.07 and $0.10 per mg of CBD.
Bath Bombs Bath bombs are generally more expensive compared to topical alternatives. They cost $0.10 to $0.60 per mg. Each bomb can cost between $10 and $30.

Bath bombs are generally more expensive than topical creams and gels. This is another downside of choosing them over topical alternatives.

However, CBD bath bombs are not just about delivering CBD. It is about the whole experience. If you fancy a hot, relaxing bath over simply applying a cream, then CBD bath bombs are worth a try.

Are There Any Side Effects of Using CBD Bath Bombs?

The general side effects of consuming CBD include nausea, vomiting, headache, dizziness, and gastrointestinal symptoms like diarrhea.

As you are not consuming CBD when you are using a CBD bath bomb, it is unlikely that you’d experience any of these side effects.

The only side effect you may experience is skin irritation due to CBD or any other ingredients used in the bath bomb formulation. These side effects can include itching, skin redness, and swelling.

Also, you should observe caution if you are pregnant or breastfeeding. CBD products, including CBD bombs, have not been tested for their safety in these conditions. You should also observe caution using CBD bath bombs on children.

How to Use CBD Bath Bombs?

Here is a step by step guide on how to use CBD bath bombs.

Step # 1: Read the Instructions Carefully

Each manufacturer has its own set of instructions. Make sure you read those instructions carefully. The instructions will also tell about the recommended dose per bath and how long to soak the bath bomb in water.

Step # 2: Soak the Bomb in Warm Water

The exact dosage depends on several factors like your weight and whether you want to try a higher or a lower dosage.

As a rule of thumb, you need a higher dose for higher body weight. Still, you should consult with your healthcare professional or the product literature if you are unsure of what dose to use.

Soak the bomb in the water. Generally, it takes only a few minutes for the bomb to completely dissolve. Again, some manufacturers recommend soaking the bomb for an extended duration to let all the oils dissolve and disperse equally into the water. Follow the product literature in that case.

Step # 3: Enjoy!

Step into the bath and enjoy!

You should immerse your body for a good 20 to 30 minutes to let the CBD interact with the endocannabinoid system of your body through your skin.

General Storage Instructions

The product should come with specific storage instructions as well. Here are some general recommendations:

  • You should keep the product in a dry and cold place. Keep it away from all sources of moisture.
  • Use the product within its expiry date.
  • Most importantly, keep all products away from the reach of children.

How to Find High Quality CBD Bath Bombs and Salts?

Are you using the right product? How do you tell if the product you are using is made of quality ingredients and is not harmful?

Whenever you are buying CBD bath bombs,-or any other CBD based products for that matter, you can tell if the product you are investing in is the right match.

There are four main factors to consider.

Factor # 1: Extraction Methods

There are two main methods of CBD extraction: ethanol (or any other organic solvent) based extraction and the CO2 extraction.

Here is a comparison.

Ethanol Based Extraction CO2 Extraction
Extraction Method Ethanol based extraction uses ethanol to draw CBD and other organic compounds from the hemp plant. Ethanol then evaporates leaving behind CBD and other organic compounds. This method uses CO2 as the main solvent. CO2 as a liquid dissolves the materials from the hemp plant. CO2 is then exposed to heat. As a result, it turns to gas and is eliminated.

It is a quick process.

Does not require a lot of fancy equipment.

Cost effective.

Product prepared in this manner is of superior quality as it is free of any solvent contamination.
Cons The process is not 100% efficient. You may be left with residues of the solvent in the CBD. This compromises the quality of the product.

The process is lengthy.

Requires fancy and costly equipment.

The process and products are expensive.

CO2 extraction is a superior process. As mentioned before, the products prepared through this process might be a little more expensive. If you are ready to pay a little extra and don’t want to compromise on the quality, then CO2 based bath bombs are the right choice.

Factor # 2: Hemp Source

The hemp source is perhaps the most crucial thing. You should look for the following qualities in the hemp source of any company you buy from.

  • The company should be able to tell you in detail about their hemp source. If they give a generic answer, perhaps they are hiding something.
  • Make sure the hemp source (the grower) is legal and authorized to cultivate and distribute hemp. Only such sources maintain the quality of their products.
  • Make sure hemp is grown in a natural environment. The hemp should be free of fertilizers, chemicals, sprays, and should be non-GMO.

Factor # 3: THC Levels

The company should clearly state the quantity of THC in its products.

Ideally, you would want a bath bomb with zero percent THC levels. Still, levels less than 0.1 percent are acceptable.

Factor # 4: Third Party Testing

Third party testing means that the company has hired an expert, independent, and neutral third party to test and evaluate their products.

During third party testing, an independent assessor tests the product to make sure:

  • The product uses the correct ingredients formulated in the right dose as advertised.
  • The product is free of additives, chemicals, solvents, bacteria, and fungi.
  • The product complies with international standards and does not contain excess THC.

If a product is third party tested, it means the company values transparency and it is confident that its products will perform according to international standards.

Final Thoughts

CBD bath bombs are a fun way to make your warm baths more relaxing and fun.

We are not completely sure if CBD bath bombs work or if they are safe to use, but considering the current state of information and the individual experience of users, they are worth a shot.
