PH ndale. Kodi kusankha njira malinga ndi muyezo asidi-m'munsi?

nthawi ndithu ambiri anamva ngati lingaliro monga pH (ndale, acidic kapena zamchere). Ndi muyeso wa hydrogen ndi angapezeke onse pa chubu ndi zonona, ndi phwando pa dermatologist lapansi. Information pa pH wa khungu ndi zofunika kwambiri. Kodi chithunzi ichi? Yesetsani kumvetsa.

A pang'ono za kapangidwe ka khungu

Monga amadziwika, wosanjikiza tentha mthupi inali mu khungu khungu, amachita ntchito chitetezo. Ndi madzi-zamadzimadzi masanjidwewo munali pawiri mafuta ndi asidi chovala Markionini. Ambiri amakhulupirira kuti pH ndale - za 7, koma izi wonyenga. Zophimba ndi kufunika pH adzakhala youma ndi aakulu. Khungu wapangidwa ndi lactic ndi citric organic zidulo, choncho, koma muyezo wake si kupitirira wowawasa. Ngati dermis pali zakusokonenezedwa kapena chimasintha pH wa khungu amayamba kusintha kwambiri. Izi zikhoza kukhala chifukwa cha matenda aakulu, ndi chifukwa cha zosayenera chisamaliro chakhungu.

The pH lonse

Chinthu choyamba tiyenera kukumbukira kuti chiphunzitso cha «pH ndale" akuphatikizapo makamaka pa malo funso. Ponena khungu mtengo ndi 5,2-5,7, misozi - 7.4, ndi mu njira mankhwala ndale pH phindu - 7 mayunitsi (mwachitsanzo, madzi).

Tikudziwa kuchokera makalasi mankhwala kuti lonse bwino asidi-m'munsi zimasiyanasiyana 0 mpaka 14. Mbali pH - za theka la izo, chirichonse pansipa - niyobaba, pamwamba - zamchere. Koma malingaliro mu cosmetology, ndi «pH-ndale" amatanthauza kuti asidi-m'munsi chizindikiro ndi Kwabwino kwa mitundu yonse khungu.

Komanso, khungu wochuluka monga amayamba ndi chizindikiro ichi. khungu youma ali ndi phindu pH kuchokera 5,7 kuti 7 yachibadwa - kuchokera 5.2 kuti 5,7, wochuluka - pa 4 ndi 5.2.

mavuto apakhungu: uzingopitirira

Takambirana kale anachitira ndi choona kuti pH, koma tsopano tiyeni tikambirane za mavuto obwera ndi chizindikiro ichi. Wochuluka khungu - vuto anthu ambiri. Makamaka mu unyamata. Pafupifupi mwana amatipeza uka ziphuphu. Ndithudi, izi ndi zotsatira za kulephera zosakhalitsa m'thupi maziko. Komabe, nthawi imeneyi n'kofunika kwambiri olondola chisamaliro chakhungu.

amalangiza makolo ngati mlandu chiyani? Nthawi zambiri kusamba? Wachinyamata amachita zimenezi, koma ziphuphu zakumaso kokha kutenga yokulirapo. Chifukwa chiyani? Sopo - kumafuna kuti anachita zamchere, ndi pH ake zimasiyanasiyana mayunitsi 6 mpaka 11. ntchito kawirikawiri zimabweretsa choona kuti amatsuka kutali pamwamba wosanjikiza wa nkhope ndi sing'anga acidic. Ntchito zoteteza wa stratum corneum akugwira ntchito kotero kuti ang'onoang'ono khungu la bakiteriya asidi mchere alipo zomera wabwinobwino wa munthu, m'pamenenso iye umabala subcutaneous mafuta. Ndicho uzingopitirira: kwambiri tichapa tokha, khungu kwambiri zhirneet. A funso zachilengedwe lakuti: "Kodi ife tingachite chiyani?"

Kodi kukhala pH wa mwakale?

Kuti apulumutse nkhope amasamba zachilengedwe asidi-zamchere bwino ake, muyenera kusamalira kwambiri malonda zodzoladzola, amene ntchito mu ndondomekoyi. Sitepe yoyamba ndi kupeza zimene sopo ndi pH ndale angagwiritsidwe ntchito kusamba kawirikawiri. Ngati uyu ndithu ndi muyeso zofunika, m'munsi wa hydrogen ayenera kukhala acidic (5.5 mayunitsi). Zikuphatikizapo foams wapadera, angakhale angelo, scrubs thupi, khungu kuyeretsa kwa wochuluka (pH = 4).

Ngati palibe vuto ngati zoterozo, zikhoza kugwiritsidwa ntchito wothandizila chisamaliro ndi asidi ofooka, 5.5 mayunitsi khungu youma - kuyandikira kwa ndale - 6.5. Mulimonsemo m'pofunika kukumbukira kuti kusankha mankhwala bwino kusamalira khungu, muyenera pafupifupi zofanana ndi asidi-zamchere bwino. N'chimodzimodzinso ndi ndalama otsala a khungu. Gel osakaniza ndi pH ndale za, monga ulamuliro, oyenera khungu wouma ndi vuto ndi kusankha ndalama ndi malo pang'ono acidic.

Shampoo ndi pH misinkhu

Monga ndi katundu aliyense, shampu ali ndi pH a, ndi chilichonse mtundu, izo nzosiyana. Apa, malinga ndi malamulo zimapangidwira, akuchita ndendende lamulo lomweli: chotsikitsitsa kupita 7 mayunitsi - niyobaba, pamwamba - zamchere. Mankhwala ochapira tsitsi ndi ndale pH - ndendende 7 mayunitsi. Ndi khungu pafupifupi chilichonse amakhalabe sichinasinthe. Bwinobwino iye anali sing'anga ofooka acidic - 4.5-5.5. Izi zikutanthauza kuti kusankha shampu ayenera kwathunthu zimadalira mmene khungu sachedwa mafuta.

Mtundu youma akulimbikitsidwa kugwiritsa ntchito shampu kwambiri zamchere chifukwa aliwonse ndi - pang'ono acidic. Ngati khungu nepriveredlivyh, monga ana, m'pofunika kusankha mankhwala ochapira tsitsi ndale pH (7 mayunitsi). Mwatsoka, ochepa okha a opanga kusonyeza zimene asidi-m'munsi chizindikiro alipo mankhwala awo skincare. Iwo okha okha ndi zolemba za (kuti youma, wochuluka, khungu labwino). Izi si zolondola kwathunthu, chifukwa, monga maphunziro, zikuoneka kuti, monga ulamuliro, mankhwala ochapira tsitsi kwa khungu labwino zamchere, ndipo ayenera kukhala pang'ono acidic.

Kodi n'zotheka kudziwa pH mlingo wa khungu ndi njira?

Ambiri angakonde kuphunzira madzi ndi bwino asidi nkhani. Kunyumba, kuchita mayeso sikovuta. Izi zimafunika njira ndi chizindikiro asidi-m'munsi, monga ulamuliro, litmus Mzere. Iwo anamiza mu njira ndipo anaikidwa pa pepala woyera. Nthawi yomweyo, kuwonetsera kumaonekeranso mtundu. Pansi akufuna mtundu lonse, n'zotheka kudziwa malo acidic kapena zamchere. Mwachitsanzo, ngati litmus choviikidwa mu sopo, ndiye iye adzapereka mtundu buluu mu malo acidic - wofiira.

Njira ina tipeze chimene pH, - ndi pH-mita. Izi ndi mkulu kwambiri kufunika chipangizo ndi mkulu molondola mtima. Izo ntchito m'mafakitale kumene kulamulira chilengedwe chofunika (kupanga mafuta, mankhwala ndi utoto mafakitale ndi ena.). Chotero chipangizo akhoza kupezeka phwando pa dermatologist lapansi. M'nkhaniyi, tinaphunzira kuti pH izi, ndipo asanaganize mmene kusankha zodzikongoletsera bwino kusamalira khungu malinga ndi muyezo wawo asidi-zamchere.
