In the world of natural health remedies, two substances frequently come up in conversations for their health benefits and uses—bentonite clay and diatomaceous earth. Both are known for detoxifying properties, skincare applications, and even benefits for digestive health. But despite some overlap in their uses, they are distinct in their composition, benefits, and applications. This blog post will explore the key differences between diatomaceous earth and bentonite clay, so you can make an informed decision on which is right for your needs.
What is Diatomaceous Earth?
Diatomaceous earth DE is a naturally occurring, soft, siliceous sedimentary rock that easily crumbles into a fine white or off-white powder. It's made up primarily of fossilized remains of diatoms—tiny aquatic organisms whose skeletons are made of silica. Over millions of years, these diatom deposits have formed layers in the earth, creating diatomaceous earth DE.
There are two types of diatomaceous earth: food grade and industrial grade. Food-grade diatomaceous earth is safe for human consumption, while industrial-grade DE is used in filtration and other non-food applications.
Key Properties of Diatomaceous Earth
Main component: Silica (about 80-90%), other minerals including calcium, magnesium, and iron.
Texture: Fine, powdery
Color: White to off-white
Polarity: Negative
pH: Neutral to slightly alkaline
Uses:
Detoxifying agent for internal use
Skincare exfoliant
Natural pest control
Soil amendment for gardening
Health and Wellness Uses of Diatomaceous Earth
Detoxification: DE’s absorbent properties can help draw out toxins from the digestive tract when consumed in small, food-grade quantities.
Skincare: DE can be used as a natural exfoliant due to its fine, abrasive texture, helping to remove dead skin cells and promote a smoother complexion.
Digestive Health: Some people use DE as a supplement to improve digestive health, as it may help with cleansing the gut.
Natural Pest Control: DE can be sprinkled around homes and gardens to deter insects. Its fine, sharp particles damage the exoskeletons of insects, causing them to dehydrate and die.
What is Bentonite Clay?
Bentonite clay, on the other hand, is composed primarily of aged volcanic ash. It is named after Fort Benton in Wyoming, where large deposits are found. The clay forms from volcanic material over long periods and is primarily composed of montmorillonite, a soft phyllosilicate mineral. Bentonite clay is well known for its swelling capacity when mixed with water, creating a thick, smooth paste.
Key Properties of Bentonite Clay
Main component: Montmorillonite (hydrated aluminum silicate)
Texture: Smooth, creamy when hydrated
Color: Usually gray, green, or cream-colored
Polarity: Negative
pH: Slightly alkaline (7-8.5)
Uses:
Detoxification (internal and external)
Skin and hair care treatments
Relief for skin conditions (e.g., acne, eczema)
Digestive health support
Health and Wellness Uses of Bentonite Clay
Detoxification: Bentonite clay works by binding to positive charge toxins and heavy metals in the body, helping to remove them through the digestive tract.
Skincare: Bentonite clay is a common ingredient in face masks due to its ability to absorb excess oil and unclog pores. It’s also soothing for skin irritation, sunburns, and insect bites.
Digestive Health: Like diatomaceous earth, bentonite clay is used for its detoxifying properties. It can soothe the digestive tract and may help relieve conditions like acid reflux or constipation.
Oral Health: Some people use bentonite clay in homemade toothpaste due to its ability to bind to toxins and harmful bacteria in the mouth.
Key Differences Between Diatomaceous Earth and Bentonite Clay
While both substances share some similarities, they have several key differences that set them apart.
Composition
Food grade DE is primarily made of silica (fossilized diatoms), while calcium bentonite clay is mostly composed of montmorillonite, a type of volcanic ash mineral.
This difference in composition gives each substance unique properties. DE’s high silica content is beneficial for hair, skin, and nails, while bentonite clay’s montmorillonite content gives it a strong negative charge, which helps in attracting and binding toxins.
Texture and Application
Diatomaceous earth is dry and powdery, with a slightly abrasive texture, making it useful as a scrub or exfoliant. Bentonite clay, when mixed with water, becomes smooth and creamy, which is ideal for topical applications like face masks and poultices.
Bentonite clay swells when hydrated, while DE remains powdery and doesn't expand.
Absorption vs. Adsorption
Diatomaceous earth works primarily through adsorption, meaning it binds toxins to its surface and removes them from the body.
Bentonite clay, on the other hand, operates by absorption, meaning it draws toxins into its structure like a sponge, particularly due to its negative ionic charge.
Detoxification Power
Both substances are used for detox, but their mechanisms are slightly different. Diatomaceous Earth DE is excellent at binding toxins in the digestive system but can also provide a gentle scrub for skin and other surfaces.
Bentonite clay’s strong negative charge makes it more effective at pulling heavy metals and toxins from the body, which is why it’s often preferred for internal detox protocols and face masks.
Insect Control
Diatomaceous earth is widely used in natural pest control, as it dehydrates insects when they come into contact with it. Bentonite clay does not have these properties and is not typically used for insect control.
Nutrient Content
Bentonite clay contains trace minerals such as magnesium, calcium, and potassium, which can benefit health when consumed in moderation. Diatomaceous earth is rich in silica, which supports healthy hair, skin, and nails.
Which one Should you Use?
For Detoxification: Both diatomaceous earth and bentonite clay can be used for detoxifying the body. If you are looking for a gentle cleanse or need help with digestive issues, food-grade diatomaceous earth is a good choice. However, if you want a stronger detox that targets heavy metals, bentonite clay may be the better option.
For Skin Care: If you’re looking for an exfoliant, DE’s fine, abrasive texture makes it ideal for scrubbing and deep-cleaning pores. Bentonite clay, however, is perfect for face masks and calming irritated skin, particularly for those with oily or acne-prone skin.
For Digestive Health: Both can aid in digestive issues, but bentonite clay is often the go-to for relief from conditions like acid reflux or bloating, as it has a calming effect on the gut.
For Pest Control: If you’re dealing with an insect problem, diatomaceous earth is the clear winner.
Conclusion
Diatomaceous earth and bentonite clay are both powerful natural substances with a wide range of uses in health, beauty, and even home care. While they share some similarities, their unique properties make them suitable for different applications. Whether you're looking to detox, improve your skincare routine, or enhance your digestive health, understanding the differences between these two can help you choose the one that best suits your needs.
Always remember to use food-grade products when ingesting or applying these substances to your skin, and consult with a healthcare professional before starting any new detox or health regimen!
