1,4-Butanediol glycidyl ether, e taʻua foi o le 1,4-butanediol dialkyl ether poʻo le BDG, o se faʻalapotopotoga faʻapitoa. O se lanu e leai se lanu samasama lanu samasama ma le maualalo o le volatility. E soluble i le tele o solvents organic e pei o le ethanol, methanol ma le dimethylformamide. E masani ona faʻaaogaina e pei o vailaʻau mataʻutia ma solvents. E faʻaaogaina foʻi e fai ma faʻamautu mo vali ma pigments. E mafai ona gaosia e ala i le esterification o le 1,4-butanediol ma le methanol poʻo le methanol solution. O tulaga faʻaalia e masani lava ona faia i lalo o le mamafa maualuga ma i le i ai o se faʻamalosi.

A faʻaaogaina le 1,4-butanediol glycidyl eter, e tatau ona faʻaeteete e puipuia le faʻafesoʻotaʻi ma le paʻu ma mata. I le taimi o le faʻaaogaina ma le teuina, e tatau ona aloese mai le maualuga o le vevela ma puna o afi. Fa'alogo lelei i le fa'amauina o atigipusa e teu ai ina ia puipuia ai le fa'asao ma le tafe.
