Inorganic Sunscreens Applications
Zodzitetezera ku dzuwa ndizoyenera kugwiritsa ntchito chitetezo chilichonse cha UV kupatula zopangira zomveka bwino kapena zopopera za aerosol. Iwo ali oyenerera makamaka chisamaliro cha dzuwa la ana, mankhwala okhudzidwa ndi khungu, mankhwala omwe amapanga "zachilengedwe" zodzikongoletsera, ndi zodzoladzola zokongoletsera.
Zosefera za Inorganic UV Chemical Types

Titaniyamu dioxide
• Kwenikweni fyuluta ya UVB, koma magiredi ena amaperekanso chitetezo chabwino cha UVA
• Magiredi osiyanasiyana omwe amapezeka ndi makulidwe osiyanasiyana a tinthu, zokutira ndi zina.
• Magiredi ambiri amagwera m'malo a nanoparticles
• Tinthu ting'onoting'ono tating'onoting'ono timaonekera kwambiri pakhungu koma sizipereka chitetezo chochepa cha UVA; zazikuluzikulu zimapereka chitetezo chochulukirapo cha UVA koma zimayera kwambiri pakhungu

Zinc oxide
• Makamaka fyuluta ya UVA; kuchepetsa mphamvu ya SPF kuposa TiO2, koma imapereka chitetezo chabwinoko kuposa TiO2 m'dera lalitali la "UVA-I"
• Magiredi osiyanasiyana omwe amapezeka ndi makulidwe osiyanasiyana a tinthu, zokutira ndi zina.
• Magiredi ambiri amagwera m'malo a nanoparticles

Performance / Chemistry matrix

Mtengo kuchokera -5 mpaka +5:
-5: zotsatira zoyipa | 0: palibe kanthu | +5: zotsatira zabwino kwambiri
(Zindikirani: pamtengo ndi kuyera, "zoyipa" zikutanthauza kuti mtengo kapena kuyera kwawonjezeka.)

Zomwe Zimakhudza Kachitidwe ka Zosefera za UV

Mawonekedwe a titaniyamu woipa ndi zinc oxide amasiyana kwambiri kutengera momwe munthu amagwirira ntchito, mwachitsanzo. zokutira, mawonekedwe akuthupi (ufa, kubalalitsidwa kwamafuta, kubalalitsidwa kwamadzi).Ogwiritsa ntchito akuyenera kukambirana ndi ogulitsa asanasankhe giredi yoyenera kwambiri kuti akwaniritse zolinga zawo zantchito pamapangidwe awo.

Kuchita bwino kwa zosefera za UV zosungunuka ndi mafuta zimatengera kusungunuka kwake muzotulutsa zomwe zimagwiritsidwa ntchito popanga. Nthawi zambiri, polar emollients ndi zosungunulira zabwino kwambiri zosefera organic.

Kuchita kwa zosefera zonse za UV kumakhudzidwa kwambiri ndi machitidwe a rheological of the formulation komanso kuthekera kwake kupanga filimu yofanana, yolumikizana pakhungu. Kugwiritsiridwa ntchito kwa opanga mafilimu abwino ndi zowonjezera za rheological nthawi zambiri kumathandiza kuti zosefera zikhale bwino.
Kuphatikiza kosangalatsa kwa zosefera za UV (ma synergies)

Pali mitundu yambiri ya zosefera za UV zomwe zimawonetsa ma synergies. Zotsatira zabwino kwambiri za synergistic nthawi zambiri zimatheka pophatikiza zosefera zomwe zimayenderana mwanjira ina, mwachitsanzo: -
• Kuphatikiza zosefera zosungunuka ndi mafuta (kapena zomwazikana) ndi zosefera zosungunuka m'madzi (kapena zomwazika madzi)
• Kuphatikiza zosefera za UVA ndi zosefera za UVB
• Kuphatikiza zosefera zopanda organic ndi zosefera organic

Palinso zosakaniza zina zomwe zingapereke ubwino wina, mwachitsanzo ndizodziwika bwino kuti octocrylene imathandiza kuti chithunzi chikhazikike bwino zosefera zina za photo-labile monga butyl methoxydibenzoylmethane.

Komabe, munthu ayenera kukumbukira nthawi zonse za luntha m'derali. Pali ma patent ambiri omwe amaphatikiza zosefera za UV ndipo opanga amalangizidwa kuti nthawi zonse awonetsetse kuti kuphatikiza komwe akufuna kugwiritsa ntchito sikuphwanya ma patent a gulu lachitatu.

Sankhani Zosefera Yabwino ya UV pakupanga Zodzikongoletsera

Zotsatirazi zikuthandizani kusankha zosefera zoyenera za UV pazodzikongoletsera zanu:
1. Khazikitsani zolinga zomveka bwino za momwe ntchitoyi ikuyendera, zokongoletsa komanso zomwe mukufuna kuti mupange.
2. Yang'anani kuti ndi zosefera ziti zomwe zimaloledwa pamsika womwe mukufuna.
3. Ngati muli ndi chassis yomwe mukufuna kugwiritsa ntchito, ganizirani zosefera zomwe zingagwirizane ndi chassisyo. Komabe ngati kuli kotheka ndi bwino kusankha zosefera poyamba ndi kupanga mapangidwe mozungulira iwo. Izi ndizowona makamaka ndi zosefera za inorganic kapena particulate organic.
4. Gwiritsani ntchito malangizo ochokera kwa ogulitsa ndi/kapena zida zolosera monga BASF Sunscreen Simulator kuti muzindikire zophatikizira zomwe ziyenerakukwaniritsa cholinga cha SPFndi zolinga za UVA.

Zophatikizazi zitha kuyesedwa m'mapangidwe. Njira zoyesera za in-vitro SPF ndi UVA ndizothandiza pakadali pano kuwonetsa kuphatikiza komwe kumapereka zotsatira zabwino kwambiri pakuchita bwino - zambiri pakugwiritsa ntchito, kutanthauzira komanso zoletsa za mayesowa zitha kusonkhanitsidwa ndi maphunziro a SpecialChem e-training:UVA/SPF: Kukhathamiritsa Ma Protocol anu Oyesa

Zotsatira za mayeso, pamodzi ndi zotsatira za mayesero ena ndi kuunika (monga kukhazikika, kutetezedwa kwa chitetezo, kumva kwa khungu), kumathandiza wopanga kusankha njira zabwino kwambiri komanso kutsogolera kupititsa patsogolo kwa mapangidwe.
