What Are The Uses of Carbon Filters In Cosmetics Industries


Nowadays, cosmetics have become a part of our daily life. From waking up in the morning to go back to bed at night, we use several cosmetics types for various purposes.

The cosmetic industry defines the industry where the cosmetics are produced/manufactured and dealt out as well.

The cosmetic industry is a vast platform of versatility, and it is known for innovative products such as skin care products (toner, serum), bath products, e.g., soap, shower gel, shampoo, beauty products like lipstick, mascara, eyeliner, foundation, and whatnot.

The more innovation in this industry, the more it will become successful. The cosmetic industry always cares for the consumers’ safety and the customers’ perception of beauty.

As safety first, the manufacturer needs to ensure the safety of using their products as they are legally responsible for having faith in the company.

Cosmetics have the major five categories. They are:

  • Skincare products
  • Facecare products
  • Haircare products
  • Personal care products
  • Treatment range

What is Carbon Filter

A carbon filter contains an activated charcoal bed used to remove impurities, gases, toxins, odor, volatile organic molecules, hazardous fumes, sterilization, clarity, and avoid contaminations between substances.

The main principle of this filter is the adsorption process. Toxins and contaminants get adsorbed onto the surface of activated carbon along with them, filtered out of the main product.

How Carbon Filter Works

Activated charcoals are being used for decades and centuries, which are used primarily for detoxification and purification.

The activated carbon is famous for its larger surface area and tiny pore size.

They act as a magnet and attract all the contaminants and toxins from anywhere they contact—the activation method of the activated carbon influences the pore size distribution and the adsorption functionality and efficiency.

The pore size is a fundamental characteristic of the purification method with activated charcoal.

Activated charcoal has a different ratio of its pore size distribution like micro, meso, and macropores that decide which type of impurities you want to adsorbed with the surface.

This pore size distribution is evaluated by some standardized tests done using methylene blue, iodine, or sometimes molasses.

The adsorption takes place within the pores of activated carbon, and the impurities are adsorbed with the surface area.

When the surface area becomes saturated with the pollutants, it reaches equilibrium.

How to Use Carbon Filter Properly

  1. The carbon filter must have an adequate number of carbons for long-lasting filter life and better filtration.
  2. Carbon filters are used in various air containment equipment such as fume hood storage chambers. The manufacturer should ensure these airflow devices operate correctly.
  3. Carbon filters become saturated after some time of use when the whole surface adsorbs the maximum level of contaminants or toxins. In this case, the carbon filter needs to replace with a new one.
  4. Storing of the carbon filter is necessary to extend the filter life up to 3-5 years. The carbon filter should be appropriately kept in its original container and also in an environment which is
  • Away from direct sunlight
  • Away from dust and pests
  • Away from humidity

Carbon Filter in Cosmetic Industry

Filtration of cosmetics is essential as it is used throughout our body and different body parts on a daily basis, and you know how sensitive our skin is!

Again, the manufacturer and the company kinds of staff who deal out products will be responsible for contaminating or degrading products during production.

Impure products might contain toxins, harmful elements, lousy odor, fumes, toxic gases, which can harm the consumer, and ultimately the industry will face a significant loss.

At many stages of the whole production system of cosmetics, from the clarification of the ointments, lotions, or cream to the water used for the preparation, from formulation to the packaging, the various degrees of filtration process are a must.

Why do we do filtration?

Of course, to remove impurities, contaminants, or toxins.

Thus, cosmetics also need to be filtrated by carbon to remove dirt, to avoid contamination, to remove microorganisms, for clarity, for appealing appearance, and for point of filling security.

Microorganisms often can get the required reproducible facilities such as proper humidity, a less acidic environment, and sufficient minerals during cosmetics production.

If the cosmetics are not filtrated well and if contamination occurs during the manufacturing process between the internal and external environment due to humidity and other stuff, the product won’t serve its purpose and can be harmful to customers.

Can the product be sold?

It’s a no. Therefore, carbon filtration should be done during the steps of manufacturing cosmetics in the cosmetic industry.

Lately, people have used carbon powder for the products’ purification, but now the carbon filter tanks are vastly used in the industry.

The cosmetic products which are convenient for growing microorganisms are:

  • Shampoo
  • Toothpaste
  • Toothbrush
  • Facewash
  • Nail polish
  • Eyeliner
  • Mascara
  • Eye/lip pencils
  • Face powders
  • Shaving cream
  • Lotions and creams
  • Eye shadow
  • Soap

How the Microorganisms Get Inside of Cosmetic Products

The cosmetics industry should keep in mind that they are legally responsible for ensuring their product quality and safety.

The manufacturer should provide the consumers to serve the best products.

But sometimes cosmetics get contaminated with bacteria, fungi, and other microorganisms by irresponsibility, improper sterilization, poor handling.

  • While preparing the products by mixing raw materials with additives, they can come in contact with the microorganisms.
  • If the manufacturing conditions are not enough to make the product sterile from humidity, it can get contaminated.
  • A flawed preservation system can be a reason for contamination as the microorganisms are provided adequate humidity, minerals, temperature for growth.
  • Insufficient packaging is also a reason for contamination. The products should be kept in a sterile room or cabinet, not directly under sunlight, away from humidity, and at the required temperature.
  • The storage conditions are essential as they consider the product’s longevity. Most of the time, products become contaminated during this storing stage.

Here, we can see, at various degrees of production, the cosmetics might get affected by microorganisms, humidity, sunlight, dust, pests, the putrid smell of the additives, and so on.

To avoid the problems mentioned above, carbon filtration is highly recommended for cosmetics production in the industry.

Carbon Filter for Microorganisms

Water is a vital ingredient for producing any products in the industry. Of course, this water should be sterile before use.

For this, a Granulated Activated Carbon Filter is used to remove any bacteria and fungi.

Bacteria tend to accumulate over the carbons’ surface in the filter, and the carbon particles then drained out of the products along with the microorganisms and made the product sterile.

Carbon Filter for Removing Bad Odor

Cosmetics products need various additives and ingredients to manufacture; some can have a pleasant odor, some of them produce a terrible and unpleasant odor. We can use carbon filters to adsorb this foul odor during the manufacturing process and some pleasant aroma, which can not be applied directly to the body. It makes the product more appealing to the consumer.

Carbon Filter for Control the Color

During production, different ingredients are used, which have different colors. When they are mixed up with the raw materials, they produce an unappealing look because of the combination of different colors. When this mixture is poured into the carbon filter, the unwanted coloring materials adsorb on the carbon’s surface and wash through.

Carbon Filter for Removing Humidity and Toxic Gas

The carbon filter is not generally used for dehumidifying because it slightly adsorbs the humidity, and if a carbon filter adsorbs a considerable level of moisture, it’ll stop working to remove foul odor.

Carbon filters are often used in various air containment equipment such as fume hood, where it ensures removing toxic gases and fumes produced by chemicals during production.

Carbon Filter for Formaldehyde

Formaldehyde is a complex chemical compound with skin-irritating properties with a pungent odor, and it’s a gas at an average temperature.

Various industries use formaldehyde, and the cosmetic industry is not an exception. Formaldehyde is used in the manufacturing of shampoo, deodorant, soap, and other cosmetics.

As formaldehyde has an unpleasant odor, it has to be removed from the products. The carbon filter is used in this case and follows the adsorption principle.

The formaldehyde adsorbs onto the surface of activated carbon and gets fixed. Thus, they are filtered out of the product and make the product free from unpleasant odor.

Carbon Filter for Removing Allergens

Sometimes additives might have allergens in their property which can introduce allergic reactions to consumers.

This type of product can cause moderate to severe problems. We can use a carbon filter to remove those allergens from the product during manufacturing.

This process will also follow the adsorption principle, where the allergens will retain onto the surface of the carbon filter and come out of the product and make the product free from allergens.
