Kosmetikoetan erabiltzen diren hainbat osagai aldi berean analizatzeko hiru metodo garatu ditu EHUko ikertzaile Josu Lopez-Gazpiok.

Aintzat izanda 10.000 osagai baino gehiago erabiltzen direla gaur egun kosmetikoak egiteko, nahitaezkoa da haiek analizatzea, kontsumitzaileen segurtasuna bermatzeko.
