What Is Bentonite?

What Is Bentonite?

What is the purpose of Bentonite in personal care products? It is used for its absorbent, bulking, emulsion stabilizing, and viscosity-controlling characteristics. Bentonite absorbs liquid, increases volume or weight, helps mix ingredients and improve shelf life, and adjusts the thickness of a product.

What Are Absorbent Ingredients?

Bentonite has absorbent characteristics.

Absorbent ingredients are substances added to products to help them absorb moisture or oil. For example, in a face powder, absorbent ingredients like talc or silica help to absorb excess oil on the skin and give a matte finish. In deodorants, absorbent ingredients like baking soda or cornstarch helps to absorb sweat and moisture.

Besides cosmetic items, absorbent ingredients are found in other products like diapers. Super-absorbent polymers (SAPs) help keep babies dry by quickly absorbing and locking away moisture.

Here are some of the most common types of absorbent ingredients in cosmetics:

• Powders: Cosmetics may contain a variety of powders, such as talc, cornstarch, or silica, which can help to absorb excess oil or moisture from the skin.

• Clays: Natural clays, such as kaolin or bentonite, are often used in cosmetics as they can absorb excess oil and unwanted substances from the skin.

• Charcoal: Activated charcoal is sometimes used in cosmetics as it can absorb impurities and toxins from the skin.

• Gels: Some gels, such as aloe vera gel, can have absorbent properties and may be used in cosmetics to help soothe and moisturize the skin.

• Polymers: Certain polymers, such as polyacrylates or cross-linked polyethylene, can be used in cosmetics to absorb excess moisture from the skin or to create a smooth, matte finish.

What Are Bulking Ingredients?

Bentonite has bulking characteristics.

Bulking ingredients are substances used in products to increase their volume or weight. They are usually added to products like lotions, creams, and shampoos to make them thicker and more substantial.

Bulking ingredients can also help to stabilize the product and prevent it from separating. They may be natural, like plant-based gums, or synthetic, like polyethylene glycols (PEGs) or microcrystalline cellulose.

Bulking ingredients can sometimes dilute active ingredients, making them easier to apply to the skin. It can be instrumental in skincare products like serums or spot treatments, where high concentrations of active ingredients can be too strong for the skin.

Bulking agents are also used in other products besides cosmetics. In the food industry, bulking agents increase the volume of products like bread, cakes, and sauces. They often substitute for high-calorie ingredients like sugar or fat, lowering the products' calories while maintaining their texture and taste.

In the pharmaceutical industry, bulking agents produce tablets and capsules. They help increase the final product's volume and make it easier to handle during the manufacturing process. Bulking agents can also adjust the release rate of active ingredients in the body, providing a sustained or controlled release effect.

Here are some of the most common types of bulking ingredients in cosmetics:

• Powders: Cosmetic powders such as talc, mica, and silica are often used as bulking agents to add volume to a product.

• Polymers: Polymers such as polyethylene and polypropylene are often used as bulking agents because of their ability to absorb water and swell in size.

• Fatty acids: Fatty acids such as stearic and palmitic acids are used as bulking agents in cosmetic formulations to add texture and viscosity.

• Glycerin: Glycerin can act as a bulking agent by adding volume and texture to cosmetic products.

• Waxes: Waxes such as beeswax, carnauba wax, and candelilla wax are used as bulking agents in cosmetics to add thickness and texture.

• Emollients: Emollients such as mineral oil, petrolatum, and lanolin can also act as bulking agents by adding volume and texture to a product.

What Are Emulsion Stabilizing Ingredients?

Bentonite has emulsion stabilizing characteristics.

Emulsion stabilizing ingredients help to mix two or more ingredients that generally don't mix well, such as oil and water, to create a stable mixture. They work by coating the oil droplets in the mixture, preventing them from sticking together and separating over time.

Emulsion stabilizing ingredients make the product last longer and more effectively and ensure it doesn't look strange or separate on the shelf. By helping emulsify, these ingredients help make the product more effective and stable over time.

What Are Viscosity-Controlling Ingredients?

Bentonite has viscosity-controlling characteristics.

Viscosity-controlling ingredients increase or decrease the thickness of a product. These ingredients are essential in creating the desired texture and consistency for cosmetic products such as lotions, creams, and serums.

Increasing the viscosity of a cosmetic product can provide a thicker and more substantial texture, making it easier to apply and providing better coverage. On the other hand, decreasing the viscosity can create a lighter, more fluid consistency, allowing for quicker absorption into the skin.

Safety

Remember, always read and follow the instructions provided on product labels carefully. If you have any questions or concerns about using a product containing various ingredients, consult with your doctor or healthcare provider before use.
