Fa'amama UV fa'aletino Ituaiga Vailaau

Titanium Dioxide
• Fa'amuamua o se faamama UVB, ae o nisi togi e maua ai le puipuiga lelei o le UVA
• Fa'ailoga eseese o lo'o maua ma eseese le lapopo'a, fa'alavalava ma isi.
• O le tele o togi e pa'ū i le malo o nanoparticles
• Laiti laiti laiti e matua manino i le pa'u ae itiiti le puipuiga o le UVA; lapopo'a e maua ai le puipuiga o le UVA ae sili atu le pa'epa'e ile pa'u

Zinc Oxide
• Fa'amuamua ole faamama UVA; maualalo le malosi o le SPF nai lo le TiO2, ae sili atu le puipuiga nai lo le TiO2 i le galu umi "UVA-I" itulagi
• Fa'ailoga eseese o lo'o maua ma eseese le lapopo'a, fa'alavalava ma isi.
• O le tele o togi e pa'ū i le malo o nanoparticles

Fa'atinoga / Kemisi matrix

Fuafua mai le -5 i le +5:
-5: aafiaga leaga taua | 0: leai se aafiaga | +5: aafiaga lelei taua
(Manatua: mo le tau ma le pa'epa'e, "a'afiaga leaga" o lona uiga o le tau po'o le pa'epa'e si'itia.)

Mea e A'afia ai Fa'atinoga o UV Filters

O uiga fa'atinoga o le titanium dioxide ma le zinc oxide e eseese tele e fa'atatau i mea totino o le vasega fa'apitoa na fa'aaogaina, fa'ata'ita'iga. faʻapipiʻi, foliga faʻaletino (paʻu paʻu, faʻasalalau faʻavae suauʻu, faʻasalalau vai).E tatau i tagata fa'aoga ona fa'atalanoa ma le au fa'atau oloa a'o le'i filifilia le togi e sili ona talafeagai e fa'amalieina ai a latou fa'amoemoega fa'atinoga i totonu o latou faiga fa'avae.

O le aoga o suau'u-soluble organic UV faamama e aafia i lo latou solubility i emollients o loʻo faʻaaogaina i le faʻatulagaina. E masani lava, polar emollients o vaifofo sili ona lelei mo faamama faʻaola.

O le fa'atinoga o fa'amama uma a le UV e matua'i a'afia lava i le amio fa'a-rheological o le fa'atulagaina ma lona mafaia ona fa'atupuina se ata e tutusa lelei i luga o le pa'u. O le faʻaogaina o mea faʻataʻitaʻi ata ma mea faʻapipiʻi rheological e masani ona fesoasoani i le faʻaleleia o le aoga o le faamama.
Manaia Tu'ufa'atasiga o filiga UV (feso'ota'iga)

E tele tu'ufa'atasiga o filiga UV e fa'aalia ai fa'atasi. O aʻafiaga sili ona lelei e masani ona maua e ala i le tuʻufaʻatasia o filiga e faʻamalieina e le tasi le isi i nisi auala, mo se faʻataʻitaʻiga: -
• Tu'ufa'atasia suau'u solu (poo suau'u-taape) faamama ma vai solu (poo vai-taape) faamama
• Tuufaatasia UVA faamama ma UVB faamama
• Tu'ufa'atasia fa'amama fa'a-organic ma fa'amama fa'aola

E iai fo'i tu'ufa'atasiga fa'apitoa e mafai ona maua mai ai isi fa'amanuiaga, mo se fa'ata'ita'iga ua iloa lelei o le octocrylene e fesoasoani e fa'atumauina ai ata-fa'amautu nisi filiga fa'apitoa e pei o le butyl methoxydibenzoylmethane.

Ae ui i lea, e tatau i se tasi ona mafaufau i mea tau le atamai i lenei vaega. E tele pateni e aofia ai tu'ufa'atasiga fa'apitoa o filiga UV ma ua fautuaina fo'i tagata fa'atonu e siaki i taimi uma o le tu'ufa'atasiga latou te fa'amoemoe e fa'aoga e le solia ai so'o se pateni lona tolu.

Filifili le fa'amama sa'o UV mo lau Fa'uga Fa'alelei

O laasaga nei o le a fesoasoani ia te oe e filifili ai le faamama UV sa'o mo lau teuteuga teuteu:
1. Fa'ata'atia ni fa'amoemoega manino mo le fa'atinoga, mea fa'alelei ma fa'amoemoe mo le fa'atulagaina.
2. Siaki po'o fea filiga e fa'atagaina mo le maketi fuafuaina.
3. Afai e iai sau ta'avale fa'apitoa e te mana'o e fa'aoga, mafaufau po'o fea filiga e fetaui ma lena ta'avale. Ae peita'i afai e mafai e sili le filifilia muamua o le fa'amama ma fa'ata'atia le fa'asologa o lo'o siomia ai. E moni lava lenei mea i filiga fa'aletino po'o fa'ama'i.
4. Fa'aaoga fautuaga mai le au fa'atau oloa ma/po'o mea faigaluega vavalo e pei ole BASF Sunscreen Simulator e fa'ailoa ai fa'apotopotoga e tatauausia le SPF faamoemoeinama sini UVA.

O nei tu'ufa'atasiga e mafai ona fa'ata'ita'iina i fa'asologa. In-vitro SPF ma le UVA fa'ata'ita'iga metotia e aoga i lenei la'asaga e fa'ailoa ai po'o fea tu'ufa'atasiga e maua ai fa'ai'uga sili i tulaga o fa'atinoga - e tele fa'amatalaga e uiga i le fa'aogaina, fa'amatalaga ma tapula'a o nei su'ega e mafai ona fa'aputuina i le SpecialChem e-training course:UVA/SPF: Fa'amalieina au Su'ega Protocols

O fa'ai'uga o su'ega, fa'atasi ai ma fa'ai'uga o isi su'ega ma su'esu'ega (fa'ata'ita'iga. mautu, fa'asao lelei, lagona o le pa'u), e mafai ai e le tagata fa'apipi'i ona filifili le filifiliga e sili ona lelei (s) ma ta'ita'ia ai fo'i le fa'atupuina atili o le (s).
