• Haholo-holo ke sefe sa UVB, empa mefuta e meng e boetse e fana ka tšireletso e ntle ea UVA
• Mekhahlelo e fapaneng e fumaneha ka boholo bo fapaneng ba dikarolwana, dikobo jj.
• Bongata ba dikereiti di wela sebakeng sa nanoparticles
• Dikarolwana tse nyane di bonaletsa haholo letlalong empa ha di na tshireletso e ngata ya UVA; dikarolwana tse kgolo di fana ka tshireletso e eketsehileng ya UVA empa di sweufatsa letlalo haholo.

Mabaka a Amang Tshebetso ea Li-UV Filters

Litšobotsi tsa ts'ebetso ea titanium dioxide le zinc oxide li fapana haholo ho latela thepa ea motho ka mong ea sehlopha se itseng se sebelisitsoeng, mohlala, ho koahela, sebopeho sa 'mele (phofo, ho hasana ho thehiloeng oling, ho hasana ho thehiloeng metsing).Basebelisi ba lokela ho buisana le bafepedi pele ba kgetha sehlopha se loketseng ka ho fetisisa ho fihlela dipheo tsa bona tsa tshebetso tsamaisong ya bona ya ho etsa dihlahiswa.

Bokgoni ba difilthara tsa UV tse qhibilihang ka oli bo susumetswa ke ho qhibiliha ha tsona difilthareng tse sebediswang motswakong. Ka kakaretso, difilthara tsa polar ke disolvent tse ntle ka ho fetisisa bakeng sa difilthara tsa tlhaho.

Tshebetso ya difilthara tsohle tsa UV e susumetswa haholo ke boitshwaro ba rheological ba sebopeho le bokgoni ba yona ba ho etsa filimi e lekanang, e kopaneng letlalong. Tshebediso ya di-filthara tse loketseng le di-additives tsa rheological hangata e thusa ho ntlafatsa katleho ya difilthara.
Motsoako o Thahasellisang oa li-filters tsa UV (litšebelisano-'moho)

Ho na le metswako e mengata ya difilthara tsa UV tse bontshang ho sebetsa mmoho. Ditlamorao tse ntle ka ho fetisisa tsa ho sebetsa mmoho hangata di fihlellwa ka ho kopanya difilthara tse tlatsanang ka tsela e itseng, mohlala:-
• Ho kopanya difilthara tse qhibilihang ka oli (kapa tse hasantsoeng ka oli) le difilthara tse qhibilihang ka metsi (kapa tse hasantsoeng ka metsi)
• Ho kopanya lifilthara tsa UVA le lifilthara tsa UVB
• Ho kopanya difilthara tse sa pheleng le difilthara tsa tlhaho

Hape ho na le metswako e itseng e ka hlahisang melemo e meng, mohlala, ho tsebahala hantle hore octocrylene e thusa ho tsitsisa difilthara tse itseng tsa photo-labile tse kang butyl methoxydibenzoylmethane.

Leha ho le jwalo motho o lokela ho dula a ela hloko thepa ya kelello sebakeng sena. Ho na le dipatente tse ngata tse akaretsang metswako e itseng ya difilthara tsa UV mme di-formulator di eletswa ho hlahloba kamehla hore motswako oo ba ikemiseditseng ho o sebedisa ha o tlōle dipatente dife kapa dife tsa mokga wa boraro.

Khetha sefe se nepahetseng sa UV bakeng sa Formula ea Hao ea Botle

Mehato e latelang e tla u thusa ho khetha sefe kapa sefe se nepahetseng sa UV bakeng sa sebopeho sa hau sa botle:
1. Beha lipheo tse hlakileng bakeng sa ts'ebetso, litšobotsi tsa botle le lipolelo tse reriloeng bakeng sa tlhahiso.
2. Hlahloba hore na ke difiltara dife tse dumelletsweng mmarakeng o rerilweng.
3. Haeba o na le chassis e itseng ea tlhahiso eo o batlang ho e sebelisa, nahana hore na ke li-filter life tse tla lumellana le chassis eo. Leha ho le joalo, haeba ho khoneha, ho molemo ho khetha li-filter pele le ho rala mokhoa o li potileng. Sena ke 'nete haholo-holo ka li-filter tse sa pheleng kapa tsa lintho tse phelang.
4. Sebelisa likeletso tse tsoang ho bafepedi le/kapa lisebelisoa tsa ho bolela esale pele tse kang BASF Sunscreen Simulator ho khetholla metsoako e lokelang hoho fihlella SPF e reriloengle lipheo tsa UVA.

Metswako ena e ka lekoa ka mekhoa. Mekhoa ea tlhahlobo ea SPF le UVA ea ka hare ho vitro e thusa mohatong ona ho bontša hore na ke metswako efe e fanang ka liphetho tse ntle ka ho fetisisa mabapi le ts'ebetso - tlhaiso-leseling e batsi mabapi le ts'ebeliso, tlhaloso le meeli ea liteko tsena e ka bokelloa ka thupelo ea koetliso ea e-e ea SpecialChem:UVA/SPF: Ho ntlafatsa Melao ea hau ea Teko

Liphetho tsa liteko, hammoho le liphetho tsa liteko le litlhahlobo tse ling (mohlala, botsitso, katleho ea ho boloka, maikutlo a letlalo), li nolofalletsa formulator ho khetha khetho e ntle ka ho fetisisa le ho tataisa nts'etsopele e tsoelang pele ea mokhoa (litlhahlobo).
