Izihluzi ze-UV kwiMarike yoLondolozo lweLanga

Ii-sunscreens ezingezizo ezendalo Amandla kunye nobuthathaka

Amandla	Ubuthathaka
Ikhuselekile / ayicaphukisi	Imbono yobuhle obungalunganga (ukuziva kolusu kunye nokumhlophe kolusu)
ububanzi be-spectrum	Kunokuba nzima ukwenza iipowders
I-SPF ephezulu (30+) inokufikelelwa nge-active enye (TiO2)	Izinto ezingaphiliyo ziye zabandakanyeka kwingxoxo ye-nano
Ukusasazwa kulula ukukufaka
I-Photostable

Usetyenziso lweZikhuseli zeLanga ezingaphiliyo
Izithambisi zelanga ezingaphiliyo zifanelekile kuzo naziphi na izicelo zokukhusela i-UV ngaphandle kweendlela ezicacileyo okanye izitshizi ze-aerosol. Zifanelekile kakhulu ekunyamekeleni ilanga lomntwana, iimveliso zolusu ezibuthathaka, iimveliso ezenza amabango "endalo", kunye nezithambisi zokuhombisa.
Iintlobo zeekhemikhali zokucoca i-UV ezingaphiliyo

I-Titanium Dioxide
• Ngokuyintloko sisihluzo se-UVB, kodwa ezinye iintlobo zikwabonelela ngokhuseleko oluhle lwe-UVA
• Amanqanaba ahlukeneyo afumaneka ngobukhulu obahlukeneyo bee-particle, ii-coating njl.njl.
• Uninzi lwee-grades luwela kwicandelo le-nanoparticles
• Iisuntswana ezincinci zibonakala ngokucacileyo eluswini kodwa azikhuseli kangako kwi-UVA; iisuntswana ezinkulu zikhusela ngakumbi kwi-UVA kodwa zenza ulusu lube mhlophe ngakumbi.

I-Zinc Oxide
• Ngokuyintloko isihluzi se-UVA; ukusebenza kwe-SPF ephantsi kune-TiO2, kodwa sinika ukhuseleko olungcono kune-TiO2 kummandla we-“UVA-I” we-long wavelength
• Amanqanaba ahlukeneyo afumaneka ngobukhulu obahlukeneyo bee-particle, ii-coating njl.njl.
• Uninzi lwee-grades luwela kwicandelo le-nanoparticles

I-matrix yokusebenza / yeKhemistri

Izinga ukusuka kwi -5 ukuya kwi +5:
-5: isiphumo esibi esibalulekileyo | 0: akukho siphumo | +5: isiphumo esihle esibalulekileyo
(Qaphela: malunga neendleko kunye nokwenza mhlophe, "isiphumo esibi" sithetha ukuba iindleko okanye ukwenza mhlophe kuyanda.)

Izinto Ezichaphazela Ukusebenza Kwezihluzi Ze-UV

Iimpawu zokusebenza kwe-titanium dioxide kunye ne-zinc oxide zahluka kakhulu ngokuxhomekeke kwiimpawu zomntu ngamnye zodidi oluthile olusetyenzisiweyo, umz. ukugquma, uhlobo olubonakalayo (umgubo, ukusasazeka okusekwe kwioyile, ukusasazeka okusekwe emanzini).Abasebenzisi kufuneka babonisane nababoneleli ngaphambi kokuba bakhethe ibakala elifanelekileyo ukuze bahlangabezane neenjongo zabo zokusebenza kwinkqubo yabo yokwenziwa kwemveliso.

Ukusebenza kakuhle kwezihluzi ze-UV ezinyibilikayo kwioyile kuchaphazeleka kukunyibilika kwazo kwii-emollients ezisetyenziswa kwifomyula. Ngokubanzi, ii-emollients ze-polar zezona zinyibilikisi zibalaseleyo kwiihluzi ze-organic.

Ukusebenza kwazo zonke izihluzi ze-UV kuchatshazelwa kakhulu yindlela ezisebenza ngayo izinto ezisebenza nge-rheological kunye nokukwazi kwazo ukwenza ifilimu elinganayo nehambelanayo eluswini. Ukusetyenziswa kwezinto ezifanelekileyo zokufakela iifilimu kunye nezongezo ze-rheological kudla ngokunceda ukuphucula ukusebenza kwezihluzi.
Umxube onomdla wee-UV filters (iintsebenziswano)

Kukho indibaniselwano ezininzi zee-UV filters ezibonisa ukusebenzisana. Iziphumo ezilungileyo ze-synergistic zihlala zifezekiswa ngokuhlanganisa ii-filters ezihambelanayo ngandlela thile, umzekelo:-
• Ukudibanisa izihluzi ezinyibilikayo ngeoyile (okanye ezisasazekileyo ngeoyile) kunye nezihluzi ezinyibilikayo ngamanzi (okanye ezisasazekileyo ngamanzi)
• Ukudibanisa izihluzi ze-UVA nezihluzi ze-UVB
• Ukudibanisa izihluzi ezingaphiliyo kunye nezihluzi zendalo

Kukwakho nemixube ethile enokuvelisa ezinye izibonelelo, umzekelo, kwaziwa kakuhle ukuba i-octocrylene inceda ekuzinziseni ii-photo-labile filters ezithile ezifana ne-butyl methoxydibenzoylmethane.

Nangona kunjalo umntu kufuneka ahlale ekhumbula amalungelo obunikazi kweli candelo. Kukho amalungelo obunikazi amaninzi agubungela indibaniselwano ethile yee-UV filters kwaye ii-formulators ziyacetyiswa ukuba zihlale zijonga ukuba indibaniselwano abaceba ukuyisebenzisa ayiphuli naliphi na ilungelo lobunikazi lomntu wesithathu.

Khetha isihluzi se-UV esifanelekileyo kwi-Cosmetic Formulation yakho

La manyathelo alandelayo aya kukunceda ukhethe isihluzi se-UV esifanelekileyo kwifomyula yakho yokuhombisa:
1. Misela iinjongo ezicacileyo zokusebenza, iimpawu zobuhle kunye namabango ajoliswe kuwo.
2. Jonga ukuba zeziphi izihluzi ezivumelekileyo kwimarike ekujoliswe kuyo.
3. Ukuba une-chassis ethile yefomyula ofuna ukuyisebenzisa, cinga ukuba zeziphi izihluzi eziya kuhambelana ne-chassis leyo. Nangona kunjalo, ukuba kunokwenzeka, kungcono ukhethe izihluzi kuqala uze uyile ifomyula ezijikeleze zona. Oku kuyinyani ngakumbi kwizihluzi ze-inorganic okanye ze-particle organic.
4. Sebenzisa iingcebiso ezivela kubaboneleli kunye/okanye izixhobo zokuqikelela ezifana ne-BASF Sunscreen Simulator ukuze uchonge iindibaniselwano ekufunekaukufezekisa i-SPF ecetywayokunye neethagethi ze-UVA.

Ezi ndibaniselwano zinokuzanywa kwiifomyula. Iindlela zovavanyo lwe-in-vitro SPF kunye ne-UVA ziluncedo kweli nqanaba ukubonisa ukuba zeziphi iindibaniselwano ezinika iziphumo ezilungileyo ngokubhekiselele ekusebenzeni - ulwazi oluthe kratya malunga nokusetyenziswa, ukutolikwa kunye nemida yezi mvavanyo lunokuqokelelwa ngekhosi yoqeqesho lwe-e-SpecialChem:I-UVA/SPF: Ukuphucula iiProtokholi zakho zoVavanyo

Iziphumo zovavanyo, kunye neziphumo zezinye iimvavanyo kunye novavanyo (umz. ukuzinza, ukusebenza kakuhle kokugcina, ukuvakalelwa kolusu), zenza ukuba i-formulator ikhethe ukhetho (iindlela) olufanelekileyo kwaye ikwakhokela uphuhliso olongezelelekileyo lwe-formula (iindlela).
