Background information on use in cosmetics

TRIS-BIPHENYL TRIAZINE (NANO), abbreviation TBPT, is a colourless organic solid. Nano-TBPT is commercially available in the form of a colourless aqueous dispersion. TBPT is practically insoluble in water and only slightly soluble in cosmetic oils. The maximum concentration of TBPT is 10 %. Nano-TBPT is deposited as a protecting film on the upper skin layer and scatters, reflects and absorbs the UV radiation of the sun. In this way the skin is protected against UV radiation and its health damaging effects (sunburn, DNA damage, skin ageing etc). Nano-TBPT is a so-called broadband UV filter with a clear filter effect including in the long-wave UV-A(2) range. Nanoscale TBPT in sunscreens is invisible for the human eye and hence does not leave any whitish film on the skin which motivates consumers to make a more generous application. Nano-TBPT is, moreover, characterised by a particularly effective UV light filtration in a broad spectrum. UV filters minimise the undesired effects of UV radiation on the skin and are, therefore, an important component of sunscreens. By protecting the skin against the dangerous sun radiation, they contribute towards preventing premature light-caused skin ageing and skin cancer. In this connection a distinction is made between soluble organic UV filters and those based on mineral and / or organic pigments. Whereas soluble organic UV filters absorb the UV radiation, transform it into heat and form an invisible protection shield in the upper skin layer, UV filters on the basis of pigments reflect, scatter and absorb the sun radiation already on the skin surface.


Information on safe use

In accordance with the EU Cosmetics Regulation [Regulation (EC) No. 1223/2009], which applies to the entire EU market, UV filters are defined as substances which are exclusively or mainly intended to protect the skin against certain UV radiation by absorbing, reflecting or scattering UV radiation. Annex VI of the Regulation defines the substances which may be used in cosmetic products as UV filters. In this so-called positive list of the UV filters maximum concentrations are prescribed for the use of these substances in cosmetic products and, if necessary, additional conditions for use are defined. Prior to their approval in Annex VI, UV filters are examined selectively for their toxicological safety and subjected to comprehensive tests. The manufacturers must prove the health safety in extensive scientific studies. Moreover, the approved filters are re-assessed, if necessary on the basis of new scientific findings and in the event of possible conspicuous findings in market observation and the list is updated accordingly.

Regulating cosmetics

Cosmetics Ingredients are subject to regulation. Please note, different regulations may apply to cosmetic ingredients outside the EU.

Understanding your cosmetics

How are cosmetics kept safe in Europe?

Strict laws make sure that cosmetics and personal care products sold in the European Union are safe for people to use. Companies, national and European regulatory authorities share the responsibility of keeping cosmetic products safe.

What should I know about endocrine disruptors?

Some ingredients used in cosmetic products have been claimed to be ‘endocrine disruptors’ because they have the potential to mimic some of the properties of our hormones. Just because something has the potential to mimic a hormone does not mean it will disrupt our endocrine system. Many substances, including natural ones, mimic hormones but very few, and these are mostly potent medicines, have ever been shown to cause disruption of the endocrine system. The rigorous product safety assessments by qualified, scientific experts that companies are legally obliged to carry out cover all potential risks, including potential endocrine disruption.

Are cosmetics tested on animals? No!

In the European Union, testing cosmetics on animals has been fully banned since 2013. Over the last 30 years, long before a ban was in place, the cosmetics and personal care industry has invested in research and development to pioneer alternatives to animal testing tools to assess the safety of cosmetics ingredients and products.

What about allergens in cosmetics?

Many substances, natural or man-made, have the potential to cause an allergic reaction. An allergic reaction occurs when a person’s immune system reacts to substances that are harmless to most people. A substance that causes an allergic reaction is called an allergen. Cosmetics and personal care products may contain ingredients that can be allergenic for some people. This does not mean that the product is not safe for others to use.

Database

Cosmetics matter to people and play an important role in our everyday life. On average European consumers use over seven different cosmetics daily. You too? It’s only natural that you want to know more about the ingredients in those products.

In the digital world we live in, there’s a deluge of information on cosmetics. However, it can be difficult to know which sources are reliable. COSMILE Europe is a European cosmetic ingredient database that offers reliable, verified and scientifically supported information on almost 30,000 ingredients used in cosmetics.

This database will help you understand why certain ingredients are in your cosmetic products; which properties they have and much more. The database is currently available in fourteen languages with more to come.
