Ukhathalelo lwelanga, kwaye kukhuselo oluthile, yenye yeamacandelo akhula ngokukhawuleza kwimarike yobuqu.Kwakhona, ukhuseleko ngoku lubandakanywa kwiimveliso ezininzi zokusebenzisa yonke imihla (umzekelo, iimveliso zoncedo lobuso kunye ne-cosmetic yolusu), njengoko abathengi behotele besazi ngakumbi ukuba ilanga lingasebenzi kwiholide yolwandle kuphela .
Ifomula yelanga yanamhlanjekufuneka ifezekise i-SPF ephezulu kwaye icele umngeni kwimigangatho ye-UVA, ngelixa iimveliso zenza ukuba iimveliso zibaluleke ngokwaneleyo ukukhuthaza ukuthotyelwa kwabathengi, kunye neendleko ezisebenza ngokwaneleyo ukuba zifikeleleke kumaxesha anzima kwezoqoqosho.
Ukusebenza kakuhle kunye nokubaluleka, kubalulekile omnye komnye; Ukwandisa ukusebenza kweenkonzo ezisetyenzisiweyo kwenza ukuba iimveliso eziphakamileyo ze-SPF zibe zenziwe ngamanqanaba amancinci eefilitha ze-UV. Oku kuvumela ifomulator inkululeko enkulu yokuphucula ulusu. Kwelinye icala, imveliso elungileyo i-Aesthetics ikhuthaza abathengi ukuba basebenzise iimveliso ezininzi kwaye ke ngoko basondele kwi-SPF.
Iimpawu zokusebenza ekuqwalaseleni xa ukhetha iifilitha ze-UV zefomu ye-cosmetic
Ukhuseleko lweqela lomsebenzisi elinenjongo- Zonke iifilitha ze-UV ziye zavavanywa kakhulu ukuqinisekisa ukuba zikhuselekile ngokwendalo kwisicelo esifanelekileyo; Nangona kunjalo abantu abanovelwano ngabantu abanobuthathaka banokuba nempendulo ye-allergic kwiindidi ezithile zeefilitha ze-UV.
• Ukusebenza kakuhle kweSPF-Ukuxhomekeka kwi-wavelength ye-avening ephezulu yobuninzi, ubukhulu bayo bokuthathwa, kunye nobubanzi be-spectrum ye-absing.
• I-Spectrum ebanzi / i-Uva yokhuseleko-Imigangatho yelanga yale mihla iyacelwa ukuba ihlangabezane nemigangatho ethile yoKhuselo lwe-UVA, kodwa ihlala ingaqondakali kukuba ukhuseleko lwe-UVA lukwenza umnikelo kwi-SPF.
• Impembelelo kulusu lolusu-Iifilitha ezahlukeneyo ze-UV zineziphumo ezahlukileyo kwimvakalelo yolusu; Umzekelo ezinye iifilitha ze-UV ze-UV zinokuziva "zinamathela" okanye "ubunzima" kulusu, ngelixa iifiletha ezinyibilikayo zinegalelo kwisikhumba esikhoyo.
Ukubonakala kulusu-Iifilti ze-inorganic kunye neenkcukacha zezinto eziphilayo zinokubangela ukuba kubengela umhlana xa usetyenziswa kwiindawo eziphezulu; Oku kuhlala kungafuneki, kodwa kwezinye iinkqubo (umzekelo. Unonophelo lomntwana) lungabonwa njengenzuzo.
• ukufota- Iifilitha ezininzi ze-UV ze-UV ekuveliseni i-UV, ngaloo ndlela kunciphisa ukusebenza kwazo; Kodwa ezinye iifilitha zinokunceda ukuzinzisa ezi "ze-Photo-Labile" kwaye zinciphise okanye zithintele ukubola.
Ukuchasana kwamanzi-Ukuqukwethwa kweefilitha ezisekwe emanzini ecaleni kweoyile kuhlala kunika i-spf, kodwa inokwenza kube nzima ngakumbi ukufezekisa ukumelana namanzi.

I-UV Filter Chicistries
Abadlali be-sunscreen ngokubanzi bahlelwa njenge-orchereens ye-orches okanye i-inorganic sunscrinic. I-Sunscreens ye-orches ifumana ngamandla kumaza akhe kwaye zibonakale ngokucacileyo. I-Inorganic Sunscreens isebenza ngokubonakalisa okanye ukusasaza imitha ye-UV.
Masifunde malunga nabo ngokunzulu:
I-orcheree ilanga
I-Suncreens Sunscreens yaziwa ngokubaIikhemikhali ze-Clikes. Oku kubandakanya iimolekyuli ze-organic (ze-carbon esekwe) ezisebenza njengelanga ngokufunxa imitha ye-UV kwaye iguqula amandla ashushu.

Izicelo ze-orches zelanga
Iifilitha ze-organic zinokwenziwa ngokomgaqo kuzo zonke iimveliso zokhathalelo lwelanga / ze-UV kodwa zisenokungalunganga kwiimveliso zabantwana okanye ulusu olunobuthathaka ngenxa yokuphelisa abantu abanobuthathaka. Akukhethi ilungelo lokwenza "indalo" okanye "i-organic" ibango lemichiza yezokwenziwa.

Izinto ezichaphazela ukusebenza kweefilitha ze-UV
Iimpawu zentsebenzo zeTitanium diokside kunye ne-zinc veside ivele ivele ngokuxhomekeke kwipropathi nganye yebakala elithile elisetyenzisiweyo, umz. Ukudibana, ifom yomzimba (i-powder, ukusasazeka okusekwe kwi-oyile, ukusasazeka okusekwe kumanzi).Abasebenzisi kufuneka banxibelelane nabathengisi ngaphambi kokuba bakhethe inani elifanelekileyo lokuhlangabezana neenjongo zabo zokusebenza kwiNkqubo yabo.
Ukusebenza kakuhle kweefayile ze-UV ze-UV ze-UV ziphenjelelwa kukuzila kwezomoya kwazo kwi-Emolites esetyenziselwa ukwenziwa. Ngokubanzi, i-polar ye-poolar zezona zinyibilikayo ze-organic.
Ukusebenza kwazo zonke iifilitha ze-UV ziphenjelelwa ngokuziphatha kakuhle yindlela yokuziphatha kakuhle kokuqulunqwa kunye nokukwazi kwayo ukwenza ifilimu, ifilimu ehambelana nolusu. Ukusetyenziswa kweefilimu ezifanelekileyo zefilimu kunye nolondolozo lwe-gefiology kuhlala kunceda ekuphuculeni ukusebenza ngempumelelo kweefilitha.
Indibaniselwano enomdla yeefilitha ze-UV (i-Synergies)
Zininzi izinto zokudibanisa iifilitha ze-UV ezibonisa uhambo. Iziphumo ezilungileyo zokuncokola zihlala zifezekiswa ngokudibanisa iifilitha ezihambelana ngandlela thile, umzekelo: -
Ukudibanisa i-ioyile ye-oyile (okanye ukusasazeka kweoyile) Iifilitha ezinamagqabi ngamanzi (okanye ezisasazeke zamanzi)
Ukudibanisa iifilitha ze-UVA kunye neefilitha ze-UVB
Ukudibanisa iifilitha ze-inorganic ezineefilitha zezinto eziphilayo
Kukho indibaniselwano ethile enokuthi ivelise ezinye izibonelelo, umzekelo ke kwaziwa ukuba i-octocrylene inceda ukuthoba iifiliti zeFoto-labile ezifana ne-butyl ye-Obylzoylmoylmoylmoylmene.
Nangona kunjalo umntu kufuneka asoloko ekhumbula ipropathi yengqondo kule ndawo. Kukho amalungelo awodwa omenzi wechiza agubungela indibaniselwano ethile yeefilitha ze-UV kunye neefomula ezicetyiswa ukuba zihlale zijonga ukuba ukudityaniswa kwabo banomdla wokusebenzisa akuphuli amalungelo awodwa omenzi weqela lesithathu.
Khetha isihluzo sase-UV se-UV sokuQinisekisa kwakho
La manyathelo alandelayo aya kukunceda ukhethe icebo lokucoca i-UV lase-UV lokwenza kwakho i-cosmotic yakho:
1. Cwangcisa iinjongo ezicacileyo zentsebenzo, iipropathi zobuhle kwaye zenzelwe amabango okuqulunqwa.
2. Jonga ukuba zeziphi iifilitha ezivunyelweyo kwimarike ecetywayo.
3. Ukuba une-chassis ethile onqwenela ukuyisebenzisa, cinga ukuba zeziphi iifilitha eziza kulunga ne-chassis. Nangona kunjalo ukuba kunokwenzeka ukuba kungcono ukukhetha iifilitha kuqala kwaye uyilo lokuyila ngokungqongileyo. Oku kuyinyani ngakumbi nge-inorganic okanye iifilitha zezinto eziphilayo.
4. Sebenzisa ingcebiso kubathengisi kunye / okanye izixhobo zokuqikelela ezifana ne-basccreen surcreen smilator ukuchonga indibaniselwano ekufunekafezekisa i-spf ecetywayokunye neethagethi ze-UVA.
Oku kudityaniswa emva koko kuya kuzanywa kwifomu. Iindlela zovavanyo ze-VITRO SPF kunye ne-UVA zovavanyo ziluncedo kweli nqanaba ukubonisa ukuba yeyiphi indibaniselwano enika iziphumo ezilungileyo ngokwendlela yokusebenza-ulwazi kunye nokunqongophala kunye nokunqongophala kwe-ERTARCHICE:I-UVA / SPF: Ukulungiselela iiprotocol zakho zovavanyo
Iziphumo zovavanyo, kunye neziphumo zolunye uvavanyo kunye novavanyo (umz. Ukusebenza okunempumelelo, ulusu luzive khona), zenze ukuba ifomula inyule inketho (s) kunye nokukhokela ukuqhubeka kokuqulunqwa kwemigaqo (s).
