O le Light Stabilizer 622 e aofia i le tupulaga fou o le polymeric Hindered Amine Light Stabilizer, lea e matua mautu lava i le vevela. E matua fetaui lelei ma le resin, e faamalieina ai le faigofie ona fetuutuunai e faasaga i le vai ma e matua maualalo le fesuisuiai ma le femalagaiga. E mafai ona faaaogaina le Light stabilizer 622 i le PE.PP. Polystyrene, ABS, polyurethane ma le polyamide ma isi, e maua ai aafiaga sili ona lelei pe a faaaogaina faatasi ma antioxidants ma UV-absorbers. O le Light stabilizer 622 o se tasi o light stabilizer ua faamaonia e le FDA e faaaoga i afifi meaai. Faasinomaga i le PE film faatoaga: 0.3-0.6%.
