O le 4-Hydroxybenzoic acid e masani ona faʻaaogaina o se mea mata autu mo oloa vailaʻau lelei, ae o parabens, e taʻua foʻi o p-hydroxybenzoic acid esters, ua faʻaaogaina lautele o ni mea faʻasao i meaʻai, vailaʻau, ma mea teuteu. E faʻaaogaina lautele foʻi i le sauniaina o vali eseese, vailaʻau faʻamaʻi fungicides, ata vali, ma isi mea faʻapipiʻi lanu e mafai ona sosolo i le suāuu. O le polymer fou e teteʻe i le vevela maualuga o le p-hydroxybenzoic acid polyester, lea e tele ona faʻaoga, e faʻaaogaina foʻi o se mea mata autu.
E masani ona afifiina i le 25kg/talipalau, ma e mafai foi ona faia se afifi faapitoa.
