Ethyl butylacetylaminopropionate, yomwe ndi mankhwala ophera udzudzu, imagwiritsidwa ntchito kwambiri m'madzi a chimbudzi, madzi ophera udzudzu komanso mankhwala ophera udzudzu. Kwa anthu ndi nyama, imatha kuthamangitsa udzudzu, nkhupakupa, ntchentche, utitiri ndi nsabwe. Mfundo yake yophera udzudzu ndi kupanga chotchinga cha nthunzi kuzungulira khungu kudzera mu kuzizira. Chotchinga ichi chimasokoneza sensa ya tinyanga ta udzudzu kuti tizindikire kuzizira pa thupi la munthu, kuti anthu apewe kulumidwa ndi udzudzu.

Madzi ochotsa udzudzu m'chimbudzi amagwiritsidwa ntchito kwambiri chifukwa ndi osavuta kunyamula, amatha kuthamangitsa udzudzu nthawi iliyonse, ali ndi fungo lonunkhira bwino, amamveka ozizira komanso omasuka, ndipo amatha kuchepetsa kutupa, kuyabwa komanso kuchepetsa kutentha. Komabe, pogula madzi ochotsa udzudzu m'chimbudzi, tiyenera kusamala za chitetezo cha zosakaniza zochotsa udzudzu.
Pakati pa zinthu zopangidwa ndi madzi ochotsa udzudzu, zinthu zomwe zimagwiritsidwa ntchito kwambiri pochotsa udzudzu ndi “Ethyl butylacetaminopropionate” ndi “DEET”. DEET idagwiritsidwa ntchito kwambiri ngati mankhwala ochotsera udzudzu pambuyo poti idagwiritsidwa ntchito ndi anthu wamba mu 1957. Komabe, asayansi akukayikira kwambiri za chitetezo cha mankhwala ochotsera udzudzu awa. Mu zinthu za ana m'maiko ambiri, pali zoletsa pakuwonjezera DEET. Bungwe la US Food and Drug Administration likunena kuti ana osakwana miyezi iwiri sayenera kugwiritsa ntchito zinthu zomwe zili ndi DEET; Canada ikunena kuti ana osakwana miyezi 6 sayenera kugwiritsa ntchito zinthu zomwe zili ndi DEET.

KwaEthyl butylacetaminopropionateKafukufuku wa bungwe la World Health Organization akusonyeza kuti alibe zotsatirapo zoyipa pa thanzi la anthu. Nthawi yomweyo, lipoti la kafukufuku wa bungwe la United States Environmental Administration linanena kuti ngakhale kuti mankhwala ophera tizilombo ndi chinthu chopangidwa ndi anthu, chitetezo chake ndi chofanana ndi cha zinthu zachilengedwe, ndipo ndi otetezeka kwa anthu onse, kuphatikizapo makanda ndi ana, omwe ali ndi kukwiya kochepa. Amawola ndipo amatha kuwonongeka kwathunthu m'chilengedwe nthawi yochepa kwambiri.
Kaya ndi madzi ochotsa udzudzu kapena madzi ena ogwira ntchito m'chimbudzi, ayenera kugwiritsidwa ntchito moyenera malinga ndi malangizo a mankhwala kapena upangiri wachipatala kwa magulu apadera monga amayi apakati, makanda, anthu omwe ali ndi dermatitis kapena kuwonongeka kwa khungu. Kwa ana, sikoyenera kugwiritsa ntchito madzi a chimbudzi cha akuluakulu mwachindunji. Ayenera kuchepetsedwa kapena kugwiritsidwa ntchito kwa ana.
Posankha mankhwala ophera udzudzu, ogula omwe kale ankaona kuti mitundu ndi zonunkhira ndi zofunika kwambiri akhala akuganizira kwambiri za kuchuluka kwa mankhwala ophera udzudzu m'zaka zaposachedwa. Pazochitika zosiyanasiyana zogwiritsidwa ntchito komanso anthu osiyanasiyana, kuchuluka kwa mankhwala ophera udzudzu nakonso n'kosiyana. Kuchuluka kwa mankhwala ophera udzudzu oyenera ana ndi 0.31%, pomwe kwa akuluakulu ndi 1.35%.
