Kodi glycolic acid ndi chiyani?

Glycolic acid, yomwe imadziwikanso kuti hydroxyacetic acid, ndi asidi wopanda mtundu, wopanda fungo wa alpha-hydroxyl omwe nthawi zambiri amachokera ku nzimbe. Nambala ya Cas ndi 79-14-1 ndipo mankhwala ake ndi C2H4O3. Glycolic acid imathanso kupangidwa.

Glycolic acid imatengedwa kuti ndi hygroscopic (imatenga mosavuta ndikusunga madzi) crystalline solid. Glycolic acid ndi yaying'ono kwambiri mwa zipatso za acids komanso yosavuta kupanga. Mamolekyu ang'onoang'ono osavuta amanenedwa kuti amalowa pakhungu mosavuta.

Muzinthu zokongola, nthawi zambiri mumawona kuchuluka kwa glycolic acid. Mwachitsanzo, 10% glycolic acid zikutanthauza kuti 10% ya chilinganizo ndi glycolic acid. Kuchuluka kwambiri kumatanthawuza kuti ndi mankhwala amphamvu a glycolic acid.

Kodi glycolic acid imachita chiyani pakhungu lanu?

Tonsefe timawona glycolic acid mu zodzoladzola zambiri, ndiye kodi glycolic acid imakhala ndi zotsatira zotani pakhungu, kaya imatulutsa zoyipa? Tiyeni tikambirane zotsatira za glycolic acid pakhungu mwatsatanetsatane.

1. Kupukuta

Udindo wa glycolic acid pakhungu ndi kuchotsa ukalamba cuticle, komanso kuchepetsa katulutsidwe wa mafuta, ayenera kuchita ntchito yabwino chisamaliro khungu. Glycolic acid imatha kulowa pakhungu, kufulumizitsa kagayidwe kake kake kakale, ndikulimbikitsa kusinthika kwa khungu. Kugwiritsa ntchito mankhwala a glycolic acid kumatha kupangitsa khungu kukhala losalala komanso labwino, kuchepetsa kutsekeka kwa pore ndi mitu yakuda.

Glycolic acid ndi kamolekyu kakang'ono ka mankhwala, atatha kuchitapo kanthu pakhungu, amatha kufulumizitsa kagayidwe ka khungu, amasungunula maselo a khungu pamodzi, kufulumizitsa kagayidwe kachakudya pakhungu, ndikuthandizira kukalamba kwa stratum corneum. Ikhoza kulimbikitsa kusinthika kwa collagen m'thupi la munthu, kuthandizira minofu ya fiber kukonzanso, ndikupanga khungu kukhala lolimba, losalala komanso lotanuka. Kawirikawiri amafunika kuchita ntchito yabwino yoyeretsa khungu, komanso amafunika kukhala ndi zizoloŵezi zogona, kuchira kwa matendawa kungathandize kwambiri.

2. Kutseketsa

Ntchito ya glycolic acid pakhungu makamaka ndi kupha tizilombo toyambitsa matenda ndi kusungunula, komanso imakhala ndi zotsatira za kuchepa kwa ma capillaries, koma pogwiritsira ntchito, chidwi chiyenera kuperekedwa ku ntchito yosamalira khungu.

Glycolic acid ndi organic pawiri, ndi colorless manla madzi, ali ndi zina zokwiyitsa. Ngati khungu lavulala, mutha kugwiritsa ntchito glycolic acid kuti muyiphe motsogozedwa ndi dokotala, yomwe imatha kukhala ndi gawo la bactericidal, komanso kupewa matenda a bala. Kuphatikiza apo, glycolic acid ingagwiritsidwenso ntchito popanga zodzoladzola, zomwe zimatha kukhala ndi gawo la kuchepa kwa ma capillaries, omwe amatha kuchepetsa magazi pang'ono, kuti akwaniritse zodzikongoletsera.

3. Kuzimiririka mawanga

Anthu ena amasamalira kwambiri khungu posankha zodzoladzola. Kodi glycolic acid imapepuka khungu? Glycolic acid imatha kusungunula mtundu wa pigment pakhungu, chifukwa chake imakhala yothandiza pakuyera komanso kuwunikira mawanga. Kugwiritsa ntchito mankhwala okhala ndi glycolic acid kumatha kupangitsa khungu kukhala lowala komanso kupangitsa khungu kukhala lowala.

4. Imalimbikitsa kusinthika kwa khungu

Glycolic acid imatha kulimbikitsa kukula ndi kusinthika kwa khungu la collagen, mogwira mtima odana ndi ukalamba, kumapangitsa kuti khungu likhale lolimba komanso kulimba. Panthawi imodzimodziyo, glycolic acid imathanso kuonjezera chinyezi cha khungu, kupangitsa khungu kukhala lopanda madzi.

Glycolic acid amagwiritsidwa ntchito m'magawo ena

Chemical munda: Glycolic asidi angagwiritsidwe ntchito ngati fungicide, mafakitale kuyeretsa wothandizila, electroplating pamwamba mankhwala madzi, etc. Magulu ake carboxyl ndi hydroxyl kupanga kukhala wapawiri katundu wa asidi carboxylic ndi mowa, ndipo akhoza kupanga hydrophilic chelates ndi zitsulo cations kudzera kugwirizana. zomangira, zomwe zingalepheretse kukula kwa bakiteriya.

Zowonjezera za Tannery:Hydroxyacetic acidAmagwiritsidwanso ntchito ngati zowonjezera zopangira zikopa, zothira madzi m'madzi, zophera mkaka zokhetsa mkaka, zowotchera ma boiler, ndi zina.

Organic kaphatikizidwe: Glycolic acid ndi zopangira za organic synthesis, zomwe zitha kugwiritsidwa ntchito popanga diol, fiber dyeing agent, cleanant, petroleum demulsifier ndi metal chelating agent.

Unilong Industrymakamaka chinkhoswe kupanga tsiku mankhwala mankhwala. Tili ndi zaka 15 zakupanga, makamaka glycolic acid, titha kupereka milingo yosiyanasiyana ya glycolic acid yamagulu amakampani, kalasi yamankhwala tsiku lililonse ndi kalasi yamankhwala, ndiglycolic acid ufandi kuyera kwakukulu kwa 99%. Zilinso70% glycolic acid madzi. Pa nthawi yomweyi, tili ndi katundu, tikhoza kuthandizira zitsanzo zochepa, takhala tikutsatira mfundo ya "makasitomala poyamba", ngati muli ndi mafunso, mukhoza kutitumizira uthenga nthawi iliyonse, tikuyembekezera kugwira ntchito nanu. .
