Emulsifier wotsogola wa Unipromapotaziyamu cetyl phosphateYawonetsa kuti imagwira ntchito bwino kwambiri mu njira zatsopano zodzitetezera ku dzuwa poyerekeza ndi ukadaulo wofanana wa potassium cetyl phosphate emulsification. Kusinthasintha kwake komanso kugwirizana kwake kwakukulu kumathandiza kuphatikiza chitetezo cha dzuwa mu zinthu zosamalira khungu ndi zodzoladzola zomwe zimapereka ubwino wowonjezera, chitetezo chapamwamba komanso mawonekedwe okongola omwe ogula padziko lonse lapansi akufuna.
Chitetezo chokwanira padzuwa sichimangoletsa kukalamba msanga kwa khungu chifukwa cha mizere yake yaying'ono ndi makwinya: komanso chimateteza kwambiri ku kuwala kwa UV komwe kungayambitse khansa ya pakhungu. Mwamwayi, ma fyuluta a UV a masiku ano ali ndi mphamvu yoteteza ngakhale khungu losavuta kwambiri ku kuwala kwa UV kochuluka. Komabe kafukufuku akuwonetsa kuti anthu sakonda kugwiritsa ntchito mafuta oteteza khungu nthawi zambiri komanso mokwanira kuti atsimikizire chitetezo choyenera.
Zikhulupiriro, makhalidwe ndi zosowa
Anthu ogula zinthu akuoneka kuti akudziwa momwe chilengedwe chimakhudzira khungu lawo. Malinga ndi Mintel Consumer Data Charts, 41% ya akazi aku France amakhulupirira kuti chilengedwe chimakhudza mawonekedwe a khungu lawo ndipo 50% ya akazi aku Spain amakhulupirira kuti kuwala kwa dzuwa kumakhudza mawonekedwe a khungu lawo, mwachitsanzo. Komabe, 28% yokha ya anthu aku Spain amavala zodzitetezera ku dzuwa chaka chonse, 65% ya anthu aku Germany amavala zodzitetezera ku dzuwa pokhapokha ngati kuli dzuwa kunja ndipo 40% ya anthu aku Italy amavala zodzitetezera ku dzuwa pokhapokha ngati ali patchuthi.
Anthu opitilira 30% aku Germany adanena kuti sapsa msanga ndipo amakonda kukhala ndi khungu lofiirira, pomwe 46% ya anthu aku France omwe adafunsidwa adati samakhala nthawi yokwanira panja kuti agwiritse ntchito chitetezo cha dzuwa tsiku lililonse. Anthu makumi awiri ndi limodzi pa zana aliwonse aku Spain sakonda kumva chitetezo cha dzuwa pakhungu lawo.
Anthu aku China akuoneka kuti amakonda kugwiritsa ntchito mafuta oteteza ku dzuwa kuposa aku Europe, ndipo 34% ya anthu aku China amagwiritsa ntchito mafuta oteteza ku dzuwa ku nkhope m'miyezi 6 yapitayi. Azimayi ndi ambiri omwe amagwiritsa ntchito mafutawa kuposa amuna (48% poyerekeza ndi 21%).
SPF - ikakwera kwambiri, imakhala bwino
Ngakhale kuti kugwiritsa ntchito njira zodzitetezera ku dzuwa sikuli kokwanira, anthu ambiri amavomerezana posankha zinthu zodzitetezera ku dzuwa kuti 'zikakhala zapamwamba, ndiye kuti zili bwino'. Anthu 51 pa 100 aliwonse aku Europe omwe adafunsidwa adati adagwiritsapo ntchito zinthu zomwe zili ndi SPF yokwera (30-50+) ndipo angazigwiritsenso ntchito. Izi zikusiyana ndi 33% omwe angasankhe SPF yapakati (15-25) ndi 24% okha omwe angasankhe SPF yotsika (yosakwana 15).
Kupititsa patsogolo kukopa kwa malingaliro kuti tithetse kusiyana pakati pa zosowa, kupezeka ndi kulandiridwa
Malingaliro awa a ogula akuwonetsa zifukwa zingapo zomwe zimapangitsa kuti anthu asafune kugwiritsa ntchito bwino chisamaliro cha dzuwa ngakhale kuti akudziwa kufunika kodziteteza:
Zodzoladzola za dzuwa zimaonedwa kuti zimamatira komanso sizimasangalatsa;
Mafuta odzola omwe amasiya m'manja angapangitse ntchito za tsiku ndi tsiku kukhala zovuta;
Kugwiritsa ntchito zinthu zoteteza ku dzuwa kumaonedwa ngati kotenga nthawi;
Ndipo pankhani yoteteza ku dzuwa pankhope, zingasokonezenso kukongola kwa tsiku ndi tsiku.
Chifukwa chake, pali kufunika kwa njira zatsopano zodzitetezera ku dzuwa zomwe zimagwirizana ndi zodzoladzola zachikhalidwe za dzuwa ndipo zitha kuphatikizidwa mosavuta komanso moyenera m'miyoyo ya anthu yatsiku ndi tsiku komanso machitidwe awo odzisamalira. Kufunika kwakukulu kwa zinthu zosamalira kumaso nthawi zambiri monga mafuta a zilembo, makamaka, kumabweretsa mavuto atsopano - komanso mwayi - kwa opanga mankhwala.
Pachifukwa ichi, kukopa kwa zinthu zosamalira thupi tsopano kuli pamodzi ndi kugwira ntchito bwino kwa zinthu ngati chinthu chofunikira kwambiri chotsogolera zisankho.
Emulsifiers: chinthu chofunikira kwambiri pakugwira ntchito bwino komanso kuzindikira kwa malingaliro
Kuti anthu apeze SPF yambiri yomwe akufuna, mafuta oteteza ku dzuwa ayenera kukhala ndi ma fyuluta ambiri a UV. Ndipo pankhani ya mitundu yonse ya zodzoladzola, mankhwalawa ayeneranso kukhala ndi utoto wambiri monga titanium dioxide womwe umagwiritsidwa ntchito ngati utoto kapena fyuluta ya UV.
Machitidwe opangidwa ndi emulsifier amapangitsa kuti zikhale zotheka kupanga mankhwala omwe amafanana ndi kufunikira kwa ma fyuluta a UV opaka mafuta ndi chikhumbo cha zinthu zosavuta kugwiritsa ntchito ndikupanga filimu yosalala komanso yopanda mafuta pakhungu. Mu machitidwe otere, emulsifier imagwira ntchito yofunika kwambiri pakukhazikitsa emulsion, makamaka ikafunika kuphatikiza zosakaniza zovuta monga ma fyuluta a UV, utoto, mchere, ndi ethanol. Chosakaniza chomalizachi ndichofunika kwambiri, chifukwa kuwonjezera mowa mu mankhwalawa kumapereka mawonekedwe opepuka komanso kumapereka chisangalalo pakhungu.
Kutha kuwonjezera kuchuluka kwa mowa kumapatsanso opanga mankhwalawo kusinthasintha kwakukulu pakusankha kwawo njira yosungira emulsion, kapena kungachepetse kufunikira kwake.
Kapangidwe kaSmartsurfa-CPKMonga momwe phosphonolipide {lecithin ndi cephaline) imakhalira pakhungu, imakhala ndi kukoma kokoma, chitetezo champhamvu, komanso yofewa pakhungu, kotero imatha kugwiritsidwa ntchito bwino mu zinthu zosamalira ana.
Zinthu zopangidwa kuchokera ku Smartsurfa-CPK zimatha kupanga nembanemba yosalowa madzi ngati silika pakhungu, zimatha kupereka mankhwala oteteza madzi, ndipo ndizoyenera kwambiri pa mafuta oteteza dzuwa ndi maziko; Ngakhale kuti ili ndi phindu la SPF logwirizana ndi mafuta oteteza dzuwa.
(1) Ndi yoyenera kugwiritsidwa ntchito pa mitundu yonse ya zinthu zosamalira khungu la ana zomwe zimakhala zofewa kwambiri
(2) Itha kugwiritsidwa ntchito popanga mafuta osalowa madzi m'madzi ndi zinthu zoteteza ku dzuwa ndipo imatha kuwonjezera kuchuluka kwa SPF ya zinthu zoteteza ku dzuwa ngati emulsifier yayikulu.
(3) Zingabweretse khungu lofewa ngati silika pa zinthu zomaliza.
(4) Monga chophatikizana ndi emulsifier, chingakhale chokwanira kukonza kukhazikika kwa mafuta odzola
