Bio­ba­sed biode­gra­da­ble fib­re and bone adhe­si­ve mate­ri­als – Migra­ti­on of oli­go­mers from pla­s­tic mate­ri­als – new food simu­lants for non-pla­s­tic mate­ri­als – deter­mi­na­ti­on of dif­fu­si­on and par­ti­ti­on coef­fi­ci­ents of seve­ral mate­ri­als in cont­act with drin­king water and simu­lants – The rese­arch acti­vi­ties of FABES cover a wide ran­ge of issues, ran­ging from con­su­mer expo­sures to the phy­si­cal and che­mi­cal inter­ac­tions bet­ween poly­me­ric mate­ri­als and their cont­act media. You can find some examp­les of rese­arch pro­jects alre­a­dy car­ri­ed out under the hea­ding “Exper­ti­se”. The­se are car­ri­ed out for the For­schungs­ge­mein­schaft für Ver­pa­ckungs- und Lebens­mit­tel­tech­nik e.V. (FoGe) or with various insti­tu­tes, asso­cia­ti­ons, net­works and indus­try within the frame­work of EU and other projects.

Typi­cal­ly, the pro­jects are based on dif­fu­si­on pro­ces­ses of ingre­di­ents from pla­s­tic mate­ri­als, paper or card­board, prin­ting inks, var­nis­hes, adhe­si­ves and other mate­ri­als. Pack­a­gings made of the­se mate­ri­als or parts the­reof, such as bevera­ge tubes, con­tai­ners, flo­or cove­rings or other con­su­mer goods, can release ingre­di­ents into food, phar­maceu­ti­cals, cos­me­tics, water or indoor air by dif­fu­si­on, i.e. migra­ti­on or permeation.

In addi­ti­on to the addi­ti­ves used, the ingre­di­ents (“migrants”) can also be their degra­da­ti­on pro­ducts and impu­ri­ties, pro­duc­tion aids or resi­du­al mono­mers and oli­go­mers from the matrix itself.

Depen­ding on the ques­ti­on, dif­fe­rent tech­ni­ques are used or com­bi­ned. Below you will find a small selection:

  • Is it a gene­ral ques­ti­on of esti­mat­ing con­su­mer exposure?
    FABES can car­ry out cor­re­spon­ding ana­ly­ses or resort to model­ling. A wide ran­ge of ana­ly­ti­cal equip­ment and soft­ware pro­grams are available for this purpose.
  • Does the ques­ti­on ari­se as to which simu­lant is the most appro­ria­te for non-pla­s­tic materials?
    FABES can make com­pa­ri­sons bet­ween migra­ti­on into simu­lants and foodstuffs.
  • Do you want to assess the ext­ent to which the envi­ron­ment is con­ta­mi­na­ted with sub­s­tances from mate­ri­als that come into cont­act with pro­duc­tion water or coo­ling water, for exam­p­le? Or the ques­ti­on ari­ses to what ext­ent REACH sub­s­tances from mate­ri­als that come into cont­act with rain­wa­ter, for exam­p­le, con­ta­mi­na­te the envi­ron­ment? Or: Can pro­blems ari­se when mate­ri­als are stored in landfills?
    FABES can also car­ry out appro­pria­te ana­ly­ses or use model­ling to pro­vi­de you with a result based on sci­en­ti­fic data.
  • You want to use a new addi­ti­ve in a con­su­mer pro­duct and esti­ma­te how high the expo­sure via the skin is?
    FABES can car­ry out cor­re­spon­ding ana­ly­ses using sweat and fat simu­lants and resort to model­ling. The tran­si­ti­on via the skin can be deter­mi­ned more pre­cis­e­ly by using arti­fi­ci­al skin sys­tems, so-cal­led “PAMPA’s”.
  • You want to deter­mi­ne basic migrant- and mate­ri­al-spe­ci­fic para­me­ters (dif­fu­si­on coef­fi­ci­ent DP, dis­tri­bu­ti­on coef­fi­ci­ent KP/F, poly­mer-spe­ci­fic para­me­ter AP)?
    It is pos­si­ble to deter­mi­ne such para­me­ters by means of kine­tic stu­dies. Here, the time-depen­dent mass trans­fer is mea­su­red at seve­ral tem­pe­ra­tures and then “fit­ted” by model­ling. With the help of the­se para­me­ters, the migra­ti­on of sub­s­tances from the mate­ri­al can then be esti­ma­ted for a varie­ty of cont­act scenarios.
