Evaluating container/content material interactions: a problem within the cosmetics sector


Container-content compatibility is usually outlined because the assure that the qualities of a product (organoleptic, security and hygiene, and so on.) and its intrinsic properties (integrity, state of actions and efficiency, and so on.) are current all through the use life. This compatibility is a vital step within the improvement of a brand new product: it’s the solely assure of the protection and efficiency which can be introduced to customers.

For beauty manufacturers, the most important position of the packaging system on this compatibility is to guard the method of the product and to restrict the potential phenomena of absorption, adsorption, permeation, permeability or leaching: the container should not contaminate or switch compounds more likely to alter or modify the contents. Thus, compatibility consists of the truth that the “container should defend the contents till the top of its shelf life” and “not have an unacceptable impression on the packaged product“, underneath regular and foreseeable circumstances of storage and use.

There are 4 sorts of modifications induced by the degradation of the product that may have penalties on:

- its organoleptic traits,

- its chemical composition,

- its microbiological profile,

- its toxicological information.

The European Cosmetics Regulation (1223/2009 of 30 November 2009) lays down a basic rule in response to which beauty merchandise positioned in the marketplace should be secure for human well being so long as they’re used underneath regular or fairly foreseeable circumstances (Article 3). This security requirement applies to the beauty product with its packaging. Nevertheless, the Regulation will not be supposed to manage packaging, which is just referred to in the case of interactions with the content material.

Bodily stability checks

With the intention to be sure that no stability issues are induced by the kind of container and packaging used, the SCCS [1] recommends performing bodily stability checks with inert containers and people supposed to be used in the marketplace. Some producers use pharmaceutical requirements (ICH10). As well as, a information to good stability practices for beauty merchandise is being finalized throughout the ISO (ISO/AWI TR 1881112).

The soundness take a look at ensures that the product meets the anticipated bodily, chemical and microbiological requirements when saved underneath regular and fairly foreseeable circumstances. The product is thus uncovered to completely different circumstances reminiscent of temperature adjustments, humidity, or UV mild. It determines the expiry time of the product (DLU) and the interval of use after opening (PAO). This take a look at may be carried out utilizing an accelerated ageing technique (1 to three months) or in actual time.

Quantitative and qualitative integrity

The method of the product, in touch with the container can generally bear physico-chemical alterations inflicting a change in its beauty properties, the efficiency of the energetic elements or its integrity. It’s crucial on this compatibility evaluation to check, step-by-step, the potential migrations of the parts of the packaging within the method and this underneath completely different circumstances of humidity and temperature mimicking the traditional and actual circumstances of use and the potential evolutions because of the ageing of the product earlier than its expiry date.

After the bibliographic examine of potential contaminations, and earlier than any quantification by subtle analytical strategies, the compatibility of the method with its container first features a visible and sensory examine (commonplace NF-ISO-5492) of the organoleptic traits of the product, its odor, its texture, its shade particularly.

The analyses of the method carried out at completely different contact occasions and underneath numerous storage circumstances make it potential to measure: the soundness of the method and the quantitative and qualitative integrity of the beauty product due to superior analytical applied sciences reminiscent of gasoline chromatography (GC), gasoline chromatography coupled to a Mass Spectrometer (GCMS), mass spectrometry, liquid chromatography coupled to a Mass Spectrometer (UPLC MS / MS)…

These analyses coupled with managed thermal degradation will make it potential to examine if contamination from the packaging to the product takes place and if air pollution whether or not mineral, metallic or plastic damages the method within the type of traces, impurities or by the presence of prohibited substances (components, dyes, plasticizers, solvents, antioxidants).

As well as, this examine of container-content interactions may be accompanied upstream by the evaluation of the packaging itself whether or not it’s cardboard, plastic, aluminum, glass. Confronted with necessary international rules, packaging suppliers typically perform these checks upstream to make sure the conformity of their packaging with beauty use and validate that there are not any oxidation or migration phenomena.

New challenges

In contrast to the agri-food sector, the cosmetics business doesn’t at present provide a reference framework or pointers for the systematic evaluation of container-content interactions. Examine consortium bringing collectively gamers in packaging, formulation and evaluation have emerged in France current years, such because the Cosmetopack working group bringing collectively 17 companions from plastics to cosmetics producers, toxicologists, faculties, {and professional} sectors. As well as, the CosmetBooste consortium goals in partnership with numerous gamers within the sector to supply a digital experience platform to evaluate the dangers to human well being, associated to content-container interactions by way of the event of predictive fashions, and thus to advertise eco-design by way of the combination of recycled materials.

In conclusion, the examine of content-content interactions seems to be a vital step within the improvement of beauty security. In a context the place client eco-responsibility is rising and strong cosmetics (lowering the usage of packaging) have gotten increasingly current, the topic must be taken critically. As well as, the challenges of upcycling and recycling give rise to new wants for verification and validation of those containers with the intention to assure customers security and efficiency all through the usage of any beauty product.
