How nanomaterials are used in cosmetics


Nanomaterials or nanoparticles are used in various fields, in the medical field, beauty and even in the food industry. For example, in the production of cosmetics, the use of nanomaterials can lead to the production of higher quality cosmetic products compared to traditional means. Different parts of the cosmetics and personal care industries have unique methods of applying nanotechnology in their production process. Some of the most common cosmetic products containing nanomaterials are listed below:

Sunscreen: coat the skin

The beauty of sunscreens is that they allow you to soak up the sun without suffering the damaging effects of ultraviolet rays. However, without nanomaterials such as those found in zinc oxide in sunscreens, this feat is nearly impossible. When zinc oxide nanoparticles are used in the production of sunscreens, they act as a coating on the skin that protects against the sun’s ultraviolet rays.

Lotions and face masks: increased absorption

While not all lotion production involves the use of nanomaterials, some companies do add them for efficiency. However, the presence of nanoparticles helps to influence the effects of lotions on the skin. This is because nanomaterials are used to transport proteins and nutrients from the skin’s surface to even deeper layers of the skin. Considering the tiny size of these nanomaterials, it is easy for them to make their way through multiple layers of skin cells and allow the skin to efficiently absorb the proteins they carry.

Makers of cosmetic masks follow the same principle, except that gold nanoparticles are the most commonly used nanomaterials. Gold has powerful antimicrobial and anti-aging properties and is known to maintain skin glow. The use of gold-based nanomaterials in face masks has, for these reasons, proven to be very beneficial for the skin.

Shampoos and conditioners: keep hair hydrated

Compared to conventionally produced shampoos and conditioners, shampoos and conditioners made from nanomaterials are much superior. This advantage is because nanomaterials are better suited to transport proteins, active ingredients, and other supplements through the hair and scalp.

Liposomes are the most commonly used nanomaterials in this field, and they have sealing qualities. These liposomes (and other nanomaterials) form a protein cover on the scalp,

trapping moisture if necessary. Liposomes are a form of protein that the body needs, so shampoos made from nanomaterials in liposomes are generally harmless.

Toothpaste: keep bacteria at bay

Nanosilver is one of the active ingredients used in making toothpaste. Silver contains antimicrobial properties. Thus, even in small quantities, it is ideal for fighting bacteria in the mouth.

The use of nanosilver in toothpaste would have unwanted effects. When absorbed, bodily fluids can transport them to other organs, where they begin to act on local microorganisms in the organ and cells within the organ. The absorption rate, however, is relatively low. Either way, you need to be careful when using toothpaste with nanosilver.

Fragrances: Long lasting effects

Perfumes and other sprays include solid lipid nanoparticles (SLN), which are known to increase absorbency. After a perfume spray, the reason why the scent lasts much longer on the skin and in the clothes than in the air, it is these SLNs. These SLNs also ensure that your perfumes do not evaporate from their containers when stored for a long time.

Other hair care products: prevent breakage

In different types of hair care products, nanomaterials make a relatively solid appearance. By using nanomaterials that target specific sites in the body, cosmetologists have been able to produce hair care products that are highly effective in maintaining and even improving the quality and appearance of hair.

Phosphatidylcholine is a natural, biodegradable nanomaterial used in the manufacture of hair care products. It effectively treats hair loss and ensures the overall maintenance of smooth, shiny and healthy hair. One of the benefits of using biodegradable nanomaterials is that they will reduce the harmful effects of nanoparticles and ensure that the carriers and whatever they carry is absorbed. completely.

Nanomaterials: to use or not to use?

The debate on the safety of nanomaterials for cosmetic use has been going on for a long time. After weighing the pros and cons of nanomaterials, on both sides of the dividing line, solid points support their convictions. Despite the few drawbacks, the opportunities arising from the use of nanomaterials in cosmetic production are significant. If you want to start using nanomaterials, make sure the products are developed by a reliable and trustworthy company that puts customer safety first.
