Ngeempahla zendalo, eziluhlaza, ezisempilweni nezikhuselekileyo ezikhuselekileyo zokutsala ingqalelo ngakumbi, ukuphuculwa kwezinto ezisebenzayo ezivela kwimithombo yezityalo kunye nokuphuhliswa kwezona zihloko zisebenzayo zophuhliso lomzi mveliso we-cosmetics. Ukuphuhlisa ubutyebi bemithombo yesityalo ayisiyo nje ukubuyisela imbali, kodwa ukuxhasa inkcubeko yemveli yaseTshayina, ukudibanisa ithiyori yendabuko yamayeza e-China e-China, kwaye usebenzise itekhnoloji ye-biechetical yendabuko yokuphuhlisa izenzululwazi kunye nokukhuseleka I-cosmetics yendalo. Iimveliso zekhemikhali zibonelela ngezinto eziluhlaza. Ukongeza, izityalo ezikhutshelweyo zisetyenziswa ngokubanzi kumayeza, izongezo zokutya, ukutya okusebenzayo, iziselo, i-cosmetics, amanye amabala.
Izityalo ezikhuphayo. I-cosmetics yenzelwe izityalo ezikhutshelweyo njengezithako ezisebenzayo zinezibonelelo ezininzi ezithelekiswa nezixhobo zesiko Izinto zendalo zingene ngokulula kakhulu kulusu, zenza ukuba imveliso isebenze ngakumbi kwaye impembelelo ibaluleke kakhulu; Umsebenzi ungaphezulu kakhulu, njl.
Ukukhetha isityalo esifanelekileyo kunye nokongeza isixa esifanelekileyo sokukhutshwa kwezityalo kwiimveliso ze-cosmetic kunokwandisa isiphumo sayo. Imisebenzi ephambili yezityalo ezikhutshelweyo kwi-cosmetics yile: Ukulwa i-curing, ukwaluphala, ukuthuka ilanga, ukhuseleko lwelanga, i-antiseptic, kunye nokhuseleko lwezityalo luhlaza kwaye lukhuselekile.
MIsiphumo se-Oistraing
Iipropathi ezirhabaxa kwi-cosmetics zenziwa ngeendlela ezimbini: enye iphunyezwa yindlela yokutshixa kwamanzi yokuqulunqwa kwe-Hydrogen Bonds kunye neeMolekyuli zamanzi; Enye yeyokuba ioyile yenziwa ifilimu evaliweyo kumphezulu wolusu.
I-cosmetics ebizwa ngokuba yi-cosmeting ye-cosmeting yi-cosmetics equkethe izithako eziqingqiweyo ukugcina umswakama we-straneum ukubuyisela i-luster kunye ne-elasticity yolusu. Ukunyibilikisa i-cosmeting kukhutshiwe ikakhulu ngokwemifanekiso yabo: enye kukusebenzisa izinto ezigcina amanzi: enye kukusetyenziswa ngamanzi anokudityaniswa ngamandla kumphezulu wolusu ukunyibilikisa, njenge-fescerin; Enye into engekhoyo emanzini, umaleko wefilimu yokuthambisa yenziwa phezu kolusu, esebenza njengeTywina ukuthintela ukuphulukana kwamanzi, ukuze i-stratum igcina isixa esithile sokufuma, esibizwa ngokuba yimollites okanye Ii-picors, ezinjengee-petroli, ioyile, kunye nee-baxes.
Zimbalwa izityalo ezimbalwa kwisityalo esinefuthe lokungcungcutheka kunye nokunyibilikisa, njenge-aloe vera, eselwandle, iom, njl njl.
Isiphumo sokwaluphala
Ngokwanda kweminyaka, ulusu luqala ukubonisa imeko yobudala, equka ikakhulu incitshisiweyo ye-collagen, i-elastin, i-MUCOORYSACCHAACS, imithombo yegazi ibonelela ngethayile yolusu, i-elasticy yesitya segazi Udonga luyancipha, kwaye i-epidersider yesikhumba incinci incinci. Ukuncipha, ukuncitshiswa kwamafutha angaphantsi komhlaba, kwaye imbonakalo ye-wrinkles, i-chlosma kunye nemigudu yobudala.
Okwangoku, izifundo zangaphambili kwizizathu zokwahluka kwabantu zihluleki ezi zinto zilandelayo:
Olunye ukwanda kunye nokwaluphala kweeradicals zasimahla. Ii-radicals zasimahla zii-atom okanye iimolekyuli ezinee-eletroni ezingafakwanga ziveliswe ngu-themolysis of thend. Banomgangatho ophezulu womsebenzi wezikhemikhali kwaye abe ne-peroxidation enemililo engacwangciswanga. I-Lipid Peroxide (i-LPO), kunye nemveliso yayo yokugqibela, i-malondirialdehyde (MDA), inokuphendula ngeyona ndlela iphilayo kwiiseli ze-biofilm, umonakalo kwiimolekyuli ze-DNA, kunye nokuguquka kweseli okanye ukuguquka kweseli okanye ukuguquka kweseli.
Okwesibini, i-UVB kunye ne-UVA e-Uva ekukhanyiseni ilanga kunokubangela ukufuphi ulusu. I-Ultraviolet i-Ultraviolet ikakhulu ibangela ulusu luye kule ndlela ilandelayo: 1) Umonakalo kwiDNA; 2) Ukudityaniswa komnqamlezo we-collagen; 3) Ukuncitshiswa kwempendulo yomzimba ngokuphembelela indlela ethintela i-Antign-i-antign ikhutshiwe; I-4) Ukuvelisa i-radicals esebenzayo kakhulu enxibelelana nezakhiwo ezahlukeneyo ze-itricelling 5. Ngoku ngqo ukuvula umsebenzi weeseli ze-pidermal langershans, ebangela ukuba kube senze i-pimimmonosprescine yolusu. Ukongeza, ukuphazamiseka okungafunekiyo, i-metabolic, kunye neMatrix ye-MatrixloproproproProteinase iya kuchaphazela ukwaluphala kwesikhumba.
Isityalo esikhutshelweyo njengemithi ye-Elastase yeNdalo ebesingumxholo oshushu kwiminyaka nje, njenge skutelia baicalensis, i-burnet, morinda, i-shuia, i-angelica, i-angelica, i-angelica, i-angelica, njalo i-angelica, kunjalo. Iziphumo zoBoniso lophononongo: ; Ukusuka kwizityalo ezidleleneyo khupha i-DPI-engenasimahla i-DPPH, kwaye uyisebenzise kwiimveliso ezifanelekileyo zezinto ezimbi, kunye neziphumo ezilungileyo; I-Polygonam Cuspidatum inesiphumo esithile sokuthintela kwi-Elastase, ngaloo ndlela i-anti-ukwaluphala kunye nokuchasana ne-anti-finkle.
FI-chackle
Umahluko wolusu womzimba womzimba uhlala uxhomekeke kumxholo kunye nokusasazwa kwe-epidermal ye-lanin, ukujikeleza kwegazi kwe-demis, kunye nobungqingqwa be-straneum. Ubumnyama bolusu okanye ukwenziwa kwamabala amamnyama kuchaphazeleka ikakhulu kukuqokelelwa kwesixa esikhulu se-melanin, i-oxidation yolusu, i-queratity yesikhumba, kunye nokuqokelelwa kweetyhefu emzimbeni.
Kule mihla, isiphumo sokukhupha i-Freckle sifezekisiwe ikakhulu ngokuchaphazela ukwakhiwa kunye nokwanda kwe-melanin. Enye i-tyrosinase inhibitor. Kwi-curosine ukuya kwi-dopa kunye neDopa ukuya eDopaquinone, zombini ziyadinwa nguTyrosinase, ezilawula ngokuthe ngqo i-tynthesin synthesis, kwaye ichaza ukuba ingaba amasinga alandelayo anokuqhubeka.
Xa izinto ezahlukeneyo zisebenza kwi-tyrosinase yokwandisa umsebenzi wayo, i-Melanin Synthesis inyuswe, kwaye xa umsebenzi uTyrosinase uthintelwe, i-melanin syntheses iyancipha. Izifundo zibonise ukuba i-arbutin ingathintela umsebenzi weTyrosinasa kwindawo yoxinzelelo ngaphandle kwetyhefu ye-typlanoct, ibhloka i-synthesis ye-DOPA, kwaye ke ithintele imveliso ye-melanin. Abaphandi bafunda amaziko emichiza kwi-tiger ye-tixier emnyama kunye neziphumo zabo ezimhlophe, ngelixa kuvavanywa ukucaphuka kwesikhumba.
Iziphumo zophando zibonisa ukuba: phakathi kweenqobo ezi-17 ze-17 URen Hongrong et al. ungqine ngovavanyo ukuba i-welfuul yobutywala i-Lotus inesiphumo esibalulekileyo sokubonisa i-melanin. Njengohlobo olutsha lwe-arhente yokutsha ye-white evalelweyo, inokudityaniswa kwi-cream efanelekileyo kwaye inokwenziwa kukhathalelo lolusu, i-anti-alm kunye nokususwa kwe-freckle. I-cosmetics esebenzayo.
Kukho ne-reametoct ye-cytotocity cytotociety cytotocity, i-endothelthen Adagonist efumaneka kwisityalo, enokukhuthaza i-endothelin ye-golanoclocys, ukuze ithintele umahluko kwi-ratraviolet ye-radinot ye-radiation ye-radiation ye-radiation ye-radiation ye-radiation ye-radiation ye-radiation ye-radiation ye-radiation ye-radiation ye-radiation ye-radiation ye-radiation ye-radiation ye-melanin imveliso. Ngovavanyo lweseli, uFrédécric Bonté et al. ibonise ukuba i-rassocattleya entsha ye-orchid inokuthintela ngokufanelekileyo ukwenziwa kweMelanocyte. Ukongeza kwi-COSTUCT efanelekileyo ye-cosmetic kunefuthe elibonakalayo kulusu kunye nokukhanya. Zhang mu et al. Ukukhutshelwa kwaye kufundwe i-herballes efana ne-scutelia baicalensis, i-Polygomom Cuspidatum kunye ne-Burnet, kwaye iziphumo zinokunciphisa umxholo we-Intracellin, ukufezekisa Iziphumo ze-freckle mhlophe.
ukhuseleko lwelanga
Ngokubanzi, i-surcts speans isetyenziswa ngokuqhelekileyo kwi-sunscreen cosmetics yahlulwe yangamacandelo amabini: I-Abssic Abssic, enjenge-ketones; Enye i-Uv i-UV yokugubungela iiarhente ezikhuselayo, oko kukuthi ,ns zelanga, ezinjenge-TIO2, Zno. Kodwa ezi ntlobo zimbini zelanga zinokubangela ukucaphuka kolusu, i-allergies yesikhumba, kunye ne-pores evaliweyo. Nangona kunjalo, izityalo ezininzi zendalo zinefuthe elihle lokufumana i-Ultraviolet, kwaye ngokungathanga ngqo kwintsebenzo ye-sunscreen yemveliso ngokunciphisa umonakalo wemitha oye kulusu.
Ukongeza, izithako zelanga kwizityalo ezikhutshelweyo zinezibonelelo zokucaphuka kolusu, uzinzo olukwifoto, ukhuseleko kunye nokuthembeka kunye nokuthembeka kwelanga. Zheng Hongyan et al. Ikhethiwe zizityalo ezintathu zendalo, i-cortex, i-resesveraturatrol kunye ne-Arbutin, kwaye ifundwe ukhuseleko kunye ne-UVB kunye ne-UVB kunye ne-UVB kunye ne-UV eKhuselo lweZilingo zawo zelanga ngokuvavanywa kwelanga. Iziphumo zophando zibonisa ukuba: Ezinye izityalo zendalo zibonisa ifuthe lokuKhuselo lwe-UV. Isikhokelo kunye nabanye basebenzise i-turtary i-tuckat ye-flavotics njengezinto ezingafunekiyo zokufunda iipropathi ze-flavon ze-flavonoids. Olu phando lufumanise ukuba ukusetyenziswa kweeflavonoids ukuya kuthi ga kwi-emulsoons yokwenyani kunye nokudibanisa kunye ne-subscreens yomzimba kunye neekhemikhali kunikezelwe kwisiseko sethiyori kwisicelo se-susccuwnics kwixesha elizayo.
