Kodwa-ke ama-cosmetologists aletha brusochki elimnandi "ohlwini olumnyama". Ake sizame ukuthola, ukufaneleka noma ukusonga insipho yawela phansi.
Ngo-1998, u-Yuri Lozovsky washicilelwa isayensi yesayensi, lapho lo profesa enza isitatimende esingalindelekile: insipho iyingozi! Lo mbiko wagxekwa kakhulu, kodwa uLozovsky wayengaqineli - imbangela yokuguga ngaphambi kwesikhathi ikhona enqeni elimnandi. Imiphumela yokuhlola kwakhe yabonisa ukuthi isobho lonakalisa uhlaka lwe-fat protective, ngenxa yokuthi amabhaktheriya akakwazi ukungena emzimbeni wethu. Ngokwesazi sesayensi, ukwenqaba ukuhlanza "i-chemistry" kungadlulisa ukuphila okungakapheli iminyaka eyishumi. Naphezu kokuthi namuhla kukhona bobabili abalandeli bakaLozovsky nabamelene naye, bonke bavumelana ngento eyodwa: akuzona zonke izinsipho ezilimaza ngokufanayo.
Ama-slabs anamakha
Ukwethemba amehlo lapho ukhetha insipho akusizi ngalutho - ukupakisha okumibalabala, amagama okukhala, nezinsimbi eziyinkimbinkimbi. Ukungabi udokotela noma umakhemikhali, ukufunda uhlu lwezithako akusizi ngalutho ngokuphelele. Udinga nje ukulungele ukuthi uma unesipuni evamile esiqwini ngaphambi kwakho, isibonelo "i-Strawberry", "i-Glycerin", "i-Vaseline", "i-Strawberry" nokunye okunjalo, ngokuphila kwesikhala seminyaka emithathu - lokhu kungenzeka ukuthi ungumkhiqizo wamakhemikhali. Isenzo saso sisekelwe ekuhlanjweni kwamagciwane ezincane, kuyilapho ugesi nodaka luhlala khona. Yiqiniso, kanye nokuhlanzwa, le sepha iholela ekushintsheni kwe-asidi yesikhumba ukuya ohlangothini lwe-alkaline - kusuka ku-9 ukuya ku-12 (okuvamile, ngokusho kwabalobi abahlukahlukene, kuba ngu-4 kuya ku-6.8 noma 3.5 kuya ku-7.6). Futhi lokhu kusho ukuthi unqatshelwe indlela ebaluleke kunazo zonke yokuvikelwa emaceleni angaphandle, okungekho okungenakwenzeka ukulondoloza intsha. Futhi, insipho ye-alkaline ikhulula isendlalelo esinamahloni esikhumba, ivumela umswakama ukungena ngaphakathi, bese uyomisa. Ngakho-ke, kungcono ukungasebenzisi izingcezu ezinomsindo ebusweni. Insipho yesikhumba kufanelekile kuphela ukugeza izandla. Futhi emva kokuyisebenzisa, kufanele usebenzise njalo ukhilimu osondayo. Ngakho-ke, insipho ye-alkaline:
• kuphela izandla,
• Dry isikhumba,
• Isilwane sempilo iminyaka emithathu.
I-soap-keka
Ngokuqinisekile uye wavakashela izitolo ze-soapy ezitolo lapho ungathenga i-cake-soap nge-aroma-brulee iphunga, ucezu lwekhekhe elinezinwele ezintathu noma isikhwama samasipuni esiphuphuthekile ngephunga leplamu, umango, i-lemon. Noma iyiphi indlela kulezo zitolo kukhona umsebenzi wezobuciko ezinezimbali zangaphakathi ngaphakathi noma nezithelo zomisiwe. Njengomthetho, abakhiqizi bezinsipho "ezihlwabusayo" bathi imikhiqizo yabo iyimvelo ngokuphelele. Ungasheshi ukukholelwa izitatimende ezinjalo.
Insipho yangempela yemvelo ayikwazi ukukhanya, enhle nephunga elimnandi. Ukuze kuthathwe ifomu elidingekile futhi ligcinwe isikhathi eside, ikhemistri ayikwazi ukuhanjiswa nayo. Kodwa kunoma yikuphi, insipho eyenziwe ngezandla, nakuba ine-alkaline, isho umkhiqizo ongcono. Iqiniso liwukuthi ekukhiqizeni okwenziwa ngezandla (okwenziwe ngezandla) amafutha yemifino kubaluleke kakhulu, isibonelo, i-ylang-ylang, i-almond, imbewu yamagilebhisi, i-eucalyptus, i-lavender, i-mint. I-PH kumkhiqizo onjalo othakazelisayo wenza kusuka ku-7,5 kuya ku-7.8, ngakho-ke ingasetshenziswa futhi ubuso. Iqiniso, kuphela uma isikhumba singomile. Kukhona isobho "elihlwabusayo" izikhathi ezingu-10-12 ngaphezu kokuvamile. Isiqinisekiso:
• intengo yi-rubber 100-300 ngayinye g,
• impilo yokulala - engekho ngaphezu konyaka owodwa,
• iqukethe izithako zemvelo.
Insipho yamanzi
Noma kunjalo, esiseduzane nomqondo ongcono yi-soap eyetshezi, enama-surfactants noma ama-Dintegents azinyosizi, ewunakekele ngokucophelela isikhumba nasezingxenyeni ezincane ezingaphazamisi ungqimba oluvikelayo. Izinga le-pH emikhiqizo equkethe ama-surfactants ngokuvamile aphakathi kwama-5.5 kuya ku-7, kanti i-pH evamile yamakhemikhali iphezulu kakhulu-kusukela ku-9 kuya ku-12. Enye inzuzo yesobho elimanzi lilula kakhulu ukusetshenziswa. Ukuchofoza okukodwa - nesamba esifanele sokumisa okumnandi esandleni sakho. Uma unezinhlamba ezinamafutha noma ezixubekile, umkhiqizo wamanzi ulungile - uqukethe izithasiselo ezilawula ukuvikeleka kwe-sebum. Kodwa-ke, lesi sese ayifuni ukusebenzisa ubuso, ngoba lokhu kungabangela ukucasuka kwe-mucosa ye-eye. Insipho yamanzi:
• efaneleka isikhumba samafutha,
• i-pH ekahle - kusuka ku-5,5 kuya ku-7,
• ayinalo i-alkali.
Isepha ngaphandle kwensipho
Uma usondelene nesikhumba sesikhathi esidala esihle, okubangela ubudlelwane obuhle nomama wakho nobuntwana-kuhle. Ikakhulukazi kulabo bantu abano-nostalgic, ososayensi baqala "insipho ngaphandle kwensipho". Akufani nokubukeka okuvela ku-lumpy one evamile, kodwa kunokuba i-alkali eyingozi iqukethe ama-surfactants aphezulu awakwaziyo kakade. Ukuqaphela lesi sopha esimangaliso kungenziwa ekubunjweni, okuvame ukuhlanganisa cishe i-20% ye-glycerin noma i-moisturizer, okungukuthi, izingxenye ezithobisa, ezenza ngcono futhi ngesikhathi esifanayo. Ngenxa yalokhu "isepha ngaphandle kwensipho" kufanelekile kunoma yiluphi uhlobo lesikhumba, okufaka phakathi ukucasula. Ngakho, le sesephu:
• Kufanelekile kunoma yiluphi uhlobo lesikhumba,
• ayinalo i-alkali,
• Akubangeli ukucasula.
Umbono wochwepheshe
U-Irina Malitskaya, udokotela-cosmetologist, ukhetho lwesayensi yezokwelapha:
- Ngamunye wethu une-pH-inkomba ye-acid-base balance of medium, okusho ukuthi ikhambi elifanayo alinakufanele wonke umuntu ngaphandle kokuhlukile. Ngokuqondene nokungezwani komzimba, phakathi kwazo zonke izithasiselo zanamuhla eziphephile kakhulu kuze kube manje ziyi-sesame, i-peach namafutha omnqumo. Ukuthinta isikhumba esibi ngokuvamile kubangele izimali ezinokuhlanganiswa okuyinkimbinkimbi, zonke izinhlobo zephunga, amafutha esundu kanye nama-preservatives.
Izingane . Ukwakhiwa kwalo kuhlanganisa i-alkali engaphansi kakhulu kunesipuni evamile. Ifomula yezingane ituthuthukiswa ngokungezwa kwezimpawu.
I-Glycerin . Uma iphakheji ithi "isobho le-Glycerin", kusho ukuthi umenzi wakhe wanquma ukulungisa ukunakwa kwakho kule nkampani ngenhloso yokukhangisa. Ngempela, empeleni, i-glycerin, ukucwilisa isikhumba futhi ngesikhathi esifanayo ihlanza kalula, kuyisithako esikhethekile sezinsipho ezihlukahlukene, kufaka phakathi i- "Strawberry", "Flower", "Strawberry", njll.
Insipho yesikhumba . Ngaphezu ithuluzi elinjalo - ukuntuleka kwama-alkali ekubunjweni kanye nezinga le-pH elingathathi hlangothi. Yiqiniso, ucezu luvame ukushayela i-razmokaniyu ngokushesha futhi ukuxhumana namanzi kancane kancane kuyaba yi-conglomerate engena-shap.
I-soap-shampoo . Le nguqulo yensipho iningi futhi ngokuvamile ibhekiselwa kwimikhiqizo ye-class-extra. Ikhwalithi yayo ayinakuqondakala: ukungathathi hlangothi, ayiqukethe ama-alkalis. Kodwa ngeke kube nomthelela kuwo uma usebenzisa ngokunenzuzo amanzi anzima. Noma kunjalo, ungagcoki izinwele ngento yonke, ngaphambi kokushaya isikhumba se-foam bese usihlamba ngesicwebe.
Antibacterial . Ukwakhiwa kwale thuluzi kuhlanganisa izingxenye (triclosan, trikloban), ukubulala amagciwane. Kodwa ukushintsha amabhaktheriya ahlanzekile ngamabhaktheriya, izinhlobo eziningi eziphikisana nazo ziyeza. Ngaphezu kwalokho, i-triclosan, ngokusho kocwaningo, ingangena ebisi lwebele kanye ne-plasma yegazi. Ngakho-ke, ososayensi bakholelwa ukuthi izidakamizwa zokulwa nezifo zifanelekile esibhedlela, hhayi endlini ejwayelekile. Okuhlukile ngabantu abane-immune system system.
