Kodwa ke ii-cosmetologists zazisa i-brusochki ephosakeleyo "kuluhlu olumnyama". Masizame ukufumanisa, ngokufanelekileyo okanye kungabikho insipho yahlaselwa yintloni.
Ngo-1998, inqaku lezenzululwazi ngo-Yuri Lozovsky lapapashwa, apho uprofesa wenza into engalindelekanga: isepha yingozi! Le ngxelo yayigxeka kakhulu, kodwa uLozovsky wayengaqineli - imbangela yokuguga kwangaphambi kwexesha ihlala kwisiqheba esiphunga elimnandi. Iziphumo zovavanyo lwakhe zibonise ukuba isepha ichitha inqwelomoya yokukhusela, ngenxa yokuba ibhaktheriya ayikwazi ukungena emzimbeni wethu. Ngokwenzululwazi, ukwenqaba ukuhlamba "i-chemistry" kunokunyusa ubomi kungekudala iminyaka elishumi. Nangona kunjalo ukuba namhlanje banabalandeli boLozovsky kunye nabachasi bakhe, bonke bavumelana ngento enye: akuzona zonke iisepha eziyingozi.
Iibhola ezinomlilo
Ukuthembela kwamehlo xa ukhetha isepha akubalulekanga - ukupakisha okumibalabala, amagama azwakalayo kunye nezinto ezintle. Ukungabi ngugqirha okanye kumakhemikhali, ukufunda uluhlu lwezithako akunakuncedo ngokupheleleyo. Kuphela kufuneka ulungele ukuba ukuba unesepha eqhelekileyo kwisiqwenga phambi kwakho, umzekelo "i-Strawberry", "Glycerin", "Vaseline", "Strawberry" kunye nokunye, kunye ne-shelf iminyaka engama-3-oku kubakho umkhiqizo we-alkaline. Isenzo saso sisekelwe ekuhlambuleni ngokuchanekileyo kwama-microorganisms, ngelixa igrisi kunye notshisi kuhlalisa. Enyanisweni, kunye nokuhlanjululwa, le sepha iholela ekutshintsheni kwesikhumba kwinqanaba le-alkaline - ukusuka ku-9 ukuya kwe-12 (ngokuqhelekileyo, ngokubhaliweyo ngabalobi abahlukeneyo, ngu-4 ukuya ku-6.8 okanye i-3.5 ukuya ku-7.6). Kwaye oku kuthetha ukuba unqatshelwe indlela ebaluleke kakhulu yokukhusela kwimibandela yangaphandle yobundlobongela, ngaphandle kokuba akunakwenzeka ukulondoloza ulutsha. Kwakhona, insipho ye-alkaline ikhulula umgca we-horny wesikhumba, uvumele umswakama ungene ngaphakathi, uze uwume. Ngoko ke, kungcono ukuba ungasebenzisi iziqholo eziqholiweyo ebusweni. Isepha ye-alkaline ifanelekile kuphela ukuhlamba izandla. Yaye emva kokuyisebenzisa, kufuneka usebenzise ukhilimu ophuculweyo. Ngoko, isepha ye-alkaline:
• kuphela izandla,
• Yisa isikhumba,
• Ubomi bekhefu iminyaka emithathu.
Isepha
Ngokuqinisekileyo uye watyelela iintengiso ze-soapy zokuthengisa iimpahla apho ungathenga i-cake-soap nge-cream-brulee iroma, isiqwenga sekhekhe esinezintathu okanye isikhwama samasipuni aso kunye nephunga lepum, i-mango, i-lemon. Naliphi na indlela kulezo zitolo ziyimisebenzi yobugcisa kunye neentyantyambo zangaphakathi ngaphakathi okanye ngezityalo ezomileyo. Njengomthetho, abenzi be-sweets "enhle" bathi imveliso yabo yendalo. Musa ukukhawuleza ukukholelwa ezo nkcazo.
Insipho yendalo ngokwenene ayinakukhanya, inhle kwaye inomsindo. Ukuze kulandelwe ifom efunekayo kwaye igcinwe ixesha elide, i-chemistry ayikwazi ukuhanjiswa nayo. Kodwa nangona kunjalo, isepha eyenziwe ngesandla, nangona i-alkaline isiseko, ibhekisela kwimveliso engcono. Inyaniso kukuba kwimveliso eyenziwe ngesandla (eyenziwe ngezandla) ioli yemifuno ibangela ukuba, umzekelo, i-ylang-ylang, i-almond, imbewu yamagilebhisi, i-eucalyptus, i-lavender, i-mint. I-PH kwimveliso enqwenelekayo yenza ukusuka kwi-7,5 ukuya ku-7.8, ngoko ingasetyenziswa kunye nobuso. Enyanisweni, kuphela xa ulusu lumile. Kukhona "isonka esimnandi" malunga namaxesha ama-10-12 ngaphezu kwexesha eliqhelekileyo. Isiqinisekiso:
• ixabiso li-100-300 ruble nge-100 g,
Ubomi bendawo - engekho ngaphezu konyaka ongu-1,
• liqule izithako zemvelo.
Isepha
Nangona kunjalo, osondeleyo kwimeko efanelekileyo yintsipho yamanzi, ene-surfactants okanye i-Sintetic Detergents, ngokunyamekela ulusu kunye neengcinci ezincinci ezingalonakalisi ukukhusela kwayo. Iqondo le-pH kwimveliso equkethe ama-afactants ngokuvamile luqala ukusuka kuma-5.5 ukuya ku-7, ngelixa i-alkaline ye-alkaline ephezulu iphakamileyo kakhulu-ukusuka ku-9 ukuya ku-12. Enye inzuzo yesepha yamanzi iyinkululeko yokusetyenziswa kwayo. Ukucofa - kunye nenani elifanelekileyo lobunzima obuqhenqileyo esandleni sakho. Ukuba unomnxeba ocolekileyo okanye odibeneyo, umkhiqizo ococekileyo ulungile - uqulethe izongezo ezilawula ukugcinwa kwe-sebum. Nangona kunjalo, le sepha ayimfuneko ukusetyenziswa ebusweni, njengoko oku kungakhokelela ekucaseni kwe-mucosa kweso. Isepha senkunkuma:
• esifanelekileyo isikhumba somzimba,
• efanelekileyo ipH - ukusuka kwi-5,5 ukuya ku-7,
• ayinayo i-alkali.
Isepha ngaphandle kwesepha
Ukuba usondelene neqhekeza elidala lensipho, elibangela ukuba unxulumano oluhle kunye nonyoko kunye nobuntwana-kulungile. Ngokukodwa abo bantu be-nostalgic, izazinzulu zenza "isepha ngaphandle kwesepha". Ayifani ngokubonakalayo kwi-lumpy enye, kodwa endaweni ye-alkali eyingozi iqukethe ama-actif afanelekileyo aphezulu esiwaziyo. Qaphela ukuba le sepha yommangaliso inokubakho kwi-composition, edla ngokuquka malunga ne-20% ye-glycerin okanye i-moisturizer, oko kukuthi, izixhobo ezinokuthobisa, ukuthobisa kunye nexesha elifanayo lokukhusela. Ndiyabulela kule "isepha ngaphandle kwensipho" ifanelekile nayiphi na uhlobo lolusu, kuquka ukulungelelaniswa. Ngoko, le sepha:
• Ukulungele nayiphi na uhlobo lolusu,
• ayinayo i-alkali,
• Akangabangeli ukucasula.
Umbono wo bungcali
Irina Malitskaya, ugqirha-cosmetologist, umviwa wesayensi yezobugcisa:
- Ngamnye wethu unawo umqondiso we-pH we-acid-based balance of medium, oku kuthetha ukuba isilungiso esifanayo asikwazi ukulungele wonke umntu ngaphandle kokunye. Ngokubhekiselele kwimithintelo yokutya, phakathi kwazo zonke izongezelelo zanamhlanje ezikhuselekileyo kunamhlanje zi-sesame, ipereach kunye neoli yeoli. Ukuchithwa kwesikhumba okubi kuninzi kubangela ukuba imali ihlanganiswe ngama-complex compounds, zonke iintlobo zokuvumba, ioli yama-palm kunye nama-preservatives.
Bantwana . Ukubunjwa kwalo kuqukethe i-alkali engaphantsi kancinane kunesepha. Ifomula yabantwana iphuculwe ngokunyuka kweemollients.
Glycerin . Ukuba iphakhethi ithi "i-soli ye-Glycerin", kuthetha ukuba umenzi wanquma ukulungisa ingqalelo kule candelo kwiinjongo zokuthengisa. Emva koko, eqinisweni, i-glycerin, ukunyusa isikhumba kunye nexesha elifanayo ukuhlanjululwa lula, yintengiso ekhethekileyo yeentlobo ezahlukeneyo zesepha, kuquka "i-Strawberry", "Flower", "Strawberry", njl njl.
Isepha . Ngaphezu kwesi sixhobo - ukungabikho kwe-alkali ekubunjweni kunye nezinga le-pH elingathathi hlangothi. Enyanisweni, isiqwenga sithandeka kwi-razmokaniyu ngokukhawuleza kwaye ukudibanisa namanzi ngokukhawuleza kuyaba yi-conglomerate engenasiphelo.
I-soap-shampoo . Le nguqulo yesepha ayifani kwaye idla ngokubhekiselele kwimveliso yecandelo elongezelelweyo. Ubunjani bawo bungabonakali: ukungathathi hlangothi, akuququzeleli i-alkalis. Kodwa akuyi kuba nempembelelo kuyo ukuba usebenzise amanzi amanzima. Nangona kunjalo, musa ukuhlamba iinwele kunye neqhekeza lonke, u-pre-whip i-foam uze uyisitye nge-scalp.
Antibacterial . Ukubunjwa kwesi sixhobo kubandakanya izixhobo (i-triclosan, i-trikloban), ukubulala ama-microbes. Kodwa ukutshintshela ibhaktheriya ecocekileyo ngeebhaktheriya, iintlobo ezingapheliyo ziza. Ukongezelela, i-triclosan, ngokucutshungulwa kophando, inokungena ngaphakathi kubisi lwebele kunye negazi le-plasma. Ngenxa yoko, izazinzulu zikholelwa ukuba iziyobisi ezichasene nezibhedlele zifanelekile esibhedlele, kwaye kungekhona kwindlu eqhelekileyo. Ngaphandle kwabo abantu banesistim somzimba esibuthathaka.
