Ethyl butylacetylaminopropionate, chinthu chothamangitsa udzudzu, chimagwiritsidwa ntchito kwambiri m'madzi akuchimbudzi, madzi othamangitsa udzudzu komanso utsi wothamangitsa udzudzu. Kwa anthu ndi nyama, imatha kuthamangitsa udzudzu, nkhupakupa, ntchentche, utitiri ndi nsabwe. Mfundo yake yothamangitsira udzudzu ndi kupanga chotchinga cha nthunzi kuzungulira khungu kupyolera mu kutentha. Chotchinga ichi chimasokoneza sensa ya tinyanga ta udzudzu kuti tizindikire kugwedezeka kwa thupi la munthu, kuti anthu apewe kulumidwa ndi udzudzu.

Madzi a m’chimbudzi othamangitsira udzudzu amagwiritsidwa ntchito kwambiri chifukwa ndi osavuta kunyamula, amatha kuthamangitsa udzudzu nthawi iliyonse, amakhala ndi fungo lonunkhira bwino, amamva ozizira komanso omasuka, ndipo amakhala ndi zotsatirapo zochotsa kutentha, kuyabwa ndi kuchepetsa kutentha. Komabe, pogula madzi akuchimbudzi othamangitsira udzudzu, tiyenera kusamala za chitetezo cha zinthu zothamangitsira udzudzu.
Zina mwa zinthu zamadzimadzi othamangitsa udzudzu, zomwe zimagwiritsidwa ntchito kwambiri poletsa udzudzu ndi "Ethyl butylacetaminopropionate" ndi "DEET". DEET idagwiritsidwa ntchito kwambiri ngati mankhwala oletsa udzudzu pambuyo pogwiritsidwa ntchito kwa anthu wamba mu 1957. Komabe, gulu lasayansi limakayikira kwambiri za chitetezo cha mankhwala oletsa udzudzu. M'zinthu za ana m'mayiko ambiri, pali zoletsa zowonjezera za DEET. Bungwe la US Food and Drug Administration limati ana osakwana miyezi iwiri sayenera kugwiritsa ntchito mankhwala omwe ali ndi DEET; Canada imanena kuti ana osakwana miyezi 6 sangagwiritse ntchito mankhwala omwe ali ndi DEET.

ZaEthyl butylacetaminopropionate, kafukufuku wa World Health Organization amasonyeza kuti alibe zotsatirapo pa thanzi la munthu. Panthaŵi imodzimodziyo, lipoti lofufuza la United States Environmental Administration linanena kuti ngakhale kuti mankhwala ophera tizilombo ndi chinthu chopangidwa, chitetezo chake n’chofanana ndi cha zinthu zachilengedwe, ndipo n’chotetezeka kwa anthu onse, kuphatikizapo makanda ndi ana, amene sapsa mtima kwambiri. . Ndi biodegradable ndipo akhoza kuonongeka kotheratu mu chilengedwe mu nthawi yochepa kwambiri.
Kaya ndi madzi akuchimbudzi othamangitsira udzudzu kapena madzi ena achimbudzi ogwira mtima, ayenera kugwiritsidwa ntchito moyenera molingana ndi kusamala kwa mankhwala kapena malangizo achipatala kwa magulu apadera monga amayi apakati, makanda, anthu omwe ali ndi dermatitis kapena kuwonongeka kwa khungu. Kwa ana, sikuloledwa kugwiritsa ntchito madzi akuchimbudzi akuluakulu mwachindunji. Iyenera kuchepetsedwa kapena kugwiritsidwa ntchito kwa ana.
Posankha mankhwala oletsa udzudzu, ogula omwe poyamba ankayamikira zopangidwa ndi fungo lonunkhira apereka chidwi kwambiri pa zomwe zili mndandanda wa mankhwala oletsa udzudzu m'zaka zaposachedwa. Kwa zochitika zosiyanasiyana zogwiritsira ntchito ndi anthu osiyanasiyana, zomwe zili ndi mankhwala oletsa udzudzu ndizosiyana. Zomwe zili muzoletsa udzudzu zoyenera ana ndi 0,31%, pomwe zamagulu akuluakulu ndi 1.35%.
