Modern cosmetics contain a huge assortment of a wide variety of beauty products, care and decorative that perform the necessary functions: moisturizing, cleansing, nourishing the skin and hair, etc. However, many customers have reasonable questions about the compositions of these cosmetics: one or another ingredient? Will it have a negative impact? So, one of the most exciting questions for buyers is this: is benzophenone in cosmetics a harm or a benefit? Let’s figure it out!
Benzophenone is included in the composition of sunscreen products as an auxiliary UV filter. In fact, this is a whole class of ingredients, and some of its derivatives raise doubts about the safety of use. However, it remains a very common component of sunscreen cosmetics. So that you could differentiate it on the bottles of cosmetic means it can have some synonyms: Benzophenone, 2-Hydroxy-4-methoxy benzophenone, Benzophenone cryst., Benzophenone 1, Benzophenone 2, Benzophenone 3, 2.2 ‘, 4,4’-tetrahydroxy benzophenone, 2-hydroxy-4-methoxy Benzophenone-5- Sulphonic Acid. Patented formulas are:Artec Chemical Benzophenone-1, GalSORB Benzophenone-3, Haisorb 9, AgiSyn ™ 1801, Jeescreen B-3, SunCat DE, Misorb BPS9, BP-4, Sunsafe® BP1, AakoSun BP4, Escalol ™ 577 UV filter, Cromollient ™ SCE, Oxybenzone USP, LanCos UVB, Mfsorb 101, Uvinul® MS 40, Neo Heliopan® BB, CRYSPAN® BP3, EMULZOME SOLAIRE (OMC 30 / BENZO 10), Vida-Care USB-25, Olesun ™ B-4.

Action of benzophenone in cosmetics
Benzophenone is a chemical sunscreen filter that is used in sunscreens in conjunction with physical ultraviolet filters – as an auxiliary sanblock. Benzophenone cannot be used in cosmetics alone, since it does not effectively block ultraviolet, and does so selectively. At the same time, benzophenone mainly protects the skin – it helps to protect dyes, other active ingredients and fragrances contained in cosmetic preparations from degradation.The main problem with the targeted use of benzophenone is that this chemical acts as a selective UV filter: it is a secondary UVB absorber, but with activity in the UVA spectrum.
Thus, benzophenone acts as an absorber of ultraviolet radiation over a very narrow range of wavelengths and provides additional protection against solar radiation and increases the activity of SPF products. Today, as a cosmetic component, it is most often used to protect the color of cosmetic products in transparent packages.Benzophenone is used more rarely as a thermoprotector: it prevents chemical degradation of other components when exposed to high temperatures.

Indications
This component has no indications, since it is an auxiliary substance (UV filter to protect other cosmetic components).

Contraindications
Benzophenone is a non-carcinogenic and non-comedogenic component. It is non-toxic, does not provoke sensitivity or teratogenic effects. However, it can be dangerous: paradoxically, but this component often increases skin sensitivity to ultraviolet radiation when applied topically. A strict contraindication is the individual hypersensitivity reaction.

Harm of ultraviolet radiation
As you know, ultraviolet radiation to a certain extent becomes undesirable or even very dangerous for the skin and hair, because it can lead to:

  • skin dryness;
  • fragility and loss of hair shine;
  • burns and redness of the skin;
  • allergies, dermatitis;
  • premature aging, the appearance of wrinkles and age spots;
  • formation of malignant tumors, melanoma and skin cancer.

That is why the protection of hair and skin from direct sunlight is the daily task of all those who want to always be young and healthy. And no matter how much we want to get a stronger tan, we should never forget about health.

UV PROTECTION

The most effective means of protection against UV radiation are:

  • clothes;
  • hats and sunglasses;
  • special means with SPF-factor (Sun Protection Factor – “sun protection factor”).

With clothes, glasses and hats everything is very clear. And yet, how can cosmetics be protected from the insidious sun? Of course, using sunscreens based on benzophenone – benzophenone-1, benzophenone-2, that benzophenone-3, benzophenone-4, etc.

Benefit of benzophenone
Oxybenzone has a high sorption capacity, that is, the ability to absorb and reflect ultraviolet radiation, including medium-wave ultraviolet B (UVB) and near-UV-A rays (UVA). And radiation reaching the Earth’s surface contains more UV-A and, to some extent, UV-B.

Where you can meet benzophenone
T
oday, oxybenzone is one of the most commonly used organic filters in modern cosmetics. Oxybenzonecan be found in the following beauty products:

  • sunscreens and sprays;
  • decorative cosmetics (foundation creams, BB, CC, DD-creams, lipsticks, etc.);
  • nail polish;
  • lip balms;
  • oils for skin and hair;
  • perfumery;
  • hairspray, etc.

Cosmetics with benzophenone
Benzophenoneis used as an auxiliary sunscreen substance in a variety of sunscreen products. It is also used in gels and shampoos, dyes, lotions, aerosols (hair sprays), lip care products and day creams. According to the Regulations of the European Union, the maximum permissible concentration of this component in finished cosmetic products is 5% (however, in cosmetics manufactured in the USA, the content of benzophenone can reach as much as 10.0%).

Sources of benzophenone
This component is obtained exclusively synthetically, by phototransformation of other related molecules (methoxyphenylsalicylate or methoxysalicylate). Raw material is a dirty white powder. Benzophenone is very susceptible to oxidation.

Tips for selection of UVcosmetics
You should always pay attention to the composition of cosmetic and sunscreen products. Give preference to products that contain more mechanical UV filters (for example, zinc oxide or titanium dioxide) and fewer chemical filters, to which oxybenzone can be counted.Diligent manufacturers, including the Korean company Deoproce, always take care of their customers and the quality of their products, observing all the declared standards and preferring components that are harmless to the skin and the environment.In any case, you should not entirely rely solely on sunscreens and sprays. Even products with a sufficiently high protection factor (35 and above) are not quite effective in filtering the insidious rays. And for kids younger than six months and do not use sunscreen at all. Hats and clothing, as well as reducing the time spent in the open sun at the moment remain the best ways to prevent melanoma and skin aging.
