Lisebelisoa:

PABA ester e na le mefuta e mengata ea likopo ho pholletsa le liindasteri tse fapaneng.Indastering ea litlolo, e sebelisoa e le sehlaseli sa UV lihlahisoa tse sireletsang letsatsi le litlolo tse thibelang botsofali.Bokhoni ba eona ba ho monya mahlaseli a UV-B bo thusa ho sireletsa letlalo tšenyong e kotsi ea letsatsi.Ho feta moo, PABA ester e ipakile e sebetsa ho thibela ho senyeha ha li-polymers tse bakoang ke mahlaseli a kotsi a UV.Ka hona, e sebelisoa haholo ha ho etsoa lisebelisoa tse fapaneng tsa polasetiki le rabara.

Ka indasteri ea meriana, PABA ester e sebelisoa e le mohaho oa ho haha motsoako oa lithethefatsi tse sa tšoaneng.E sebetsa e le karolo e bohareng ea tlhahiso ea lithethefatsi tsa lehae, li-antimicrobial agents le litlhare tse thibelang ho ruruha.Ho feta moo, motsoako ona o na le thepa ea antioxidant, e etsang hore e be karolo ea bohlokoa ho li-supplement tsa lijo le lihlahisoa tsa phepo.

Netefaletso ea boleng:

Khamphani ea rona e latela mehato e thata ea taolo ea boleng ho netefatsa hore bareki ba rona ba fumana PABA ester ea boemo bo holimo feela.Mekhoa ea rona ea tlhahiso e latela maemo a thata a indasteri, 'me sehlopha ka seng sa sehlahisoa se etsa tlhahlobo e felletseng ea boleng laboratoring ea rona ea morao-rao.Re etelletsa pele botsitso ba sehlahisoa, bohloeki, le ts'ebetso ho fihlela litlhoko tse ikhethileng tsa bareki ba rona.

Khotsofalo ea Bareki:

Khamphani ea rona, re lumela ho aha likamano tsa nako e telele le bareki ba rona.Re fana ka litšebeletso tse potlakileng tsa bareki le tšehetso ea tekheniki ho araba lipotso kapa lipelaelo.Sehlopha sa rona se inehetseng sa litsebi se ikemiselitse ho utloisisa litlhoko tsa hau tse ikhethang le ho fana ka litharollo tse lokiselitsoeng.Re lumela ho fana ka lihlahisoa tsa boleng bo holimo ka theko ea tlholisano, ho netefatsa khotsofalo le botšepehi ba bareki.
