I-Hielscher Ultrasound Technology

Ukufudumala kwama-Cosmetic-Cosmetic Absorption by Power Ultrasonics

  • Ngenxa yesidingo esikhulayo sezimonyo ezise-eco-friendly, imboni yezimonyo igxile ekusungulweni kwe-emulsions yama-surfactant-free.
  • I-Pickering emulsions yi-surfactant- / emulsifier-free w / o- noma i-o / w-mixtures eqiniswe yizinhlayiya.
  • Ukuxubana kwe-ultrasonic kanye ne-emulsification kuyindlela ehle kakhulu yokwenza imulsion ye-Pickering ephezulu engenamathele.

 

Ultrasonic Emulsification

Amandla we-shear aphezulu anamandla avumela ukulungiselela imishini emisiwe ye-Pickering engazinzile, esebenzisa i-micron-ne-nano-particles njenge-stabilizer. I-Sonication iyi-process emulsification engeyona eyashisayo esetshenzisiwe kakade ukuze i-emulsify w / o-, o / w-, kanye ne-w / o / w-izinhlelo ukukhiqiza ama-emulsions azinzile (isb. For moisturizers, creams, lotions, sunscreens, ointments njll .).
Izingubo zokugqoka kanye nemikhiqizo eyenziwe ngobumba ikhombisa imiphumela emihle ama-stabilizer ku-Pickering emulsions. Amandla aphezulu we-shear we-emulsization ye-ultrasonic anika amandla ukuxubanisa ngisho nama-rheology modifiers, okuvame ukuthi kube nzima ukusabalalisa njengokuhluza kanye nemikhiqizo eyenziwe ngobumba ibe yimidwebo yokwenza izimonyo. Inzuzo enkulu yama-clays ukusebenza kwabo okumbaxambili njengoba bezinza i-emulsion futhi ngasikhathi sinye besebenza njengeziguquko ze-rheology ekwakhiweni. Lokhu kusho ukuthi i-sonication iyindlela enhle yokwakha i-emulsions yezimonyo enezimpawu zokunciphisa izinwele ezibuye zibe yi-thixotropic futhi inikeze ngalezo zimpawu ezinhle zohlelo lokusebenza (isib. Ukusebenzisa okulula esikhunjeni, imikhiqizo efafazwa nokunye).

Emulsion yama-Castor Oil-in-Water

Ukwakhiwa kwe-ultrasonic ye-emulsion yamafutha-ngaphakathi kwamanzi
I-Pickering yama-emulsions yamafutha angaphakathi kwamanzi angalungiswa ngale ndlela elandelayo:
Isigaba esilandelayo sinamanzi – ukusabalalisa kwe-laponite®, isigaba sangaphakathi / sahlakazeka sine-oyela we-castor.

  1. Isigaba esilandelayo silungiswa ngokuhlakaza u-2wt% laponite® powder ku-0.1M NaCl (emanzini ahlanzekile kakhulu), ehlakazeka ngokusebenzisa i-homogenizer yama-ultrasonic yama-Hielscher UP200St noma UP200Ht (200W, 26kHz) imizuzu embalwa imizuzu.
  2. Ngokuba i-o / w-emulsion, i-oyela kancane kancane ifakwe kusetshenziswa i-pipette kwisigaba se-aqueous, ngenkathi ingxube ibhekwa. Ngemuva kwe-approx. 2 imizuzu sonication, a emulsion homogeneous futhi ozinzile yenziwa. Ngenkambiso ye-emulsification, isampuli ikhohliwe ebhodini lokugezela ukuvimbela ukushisa kwesampula.
I-ultrasonic emulsification isetshenziselwa ukwenza ama-emulsions aqinile wezithokozi (Chofoza ukuze ukhulise!)

Ukwenza i-emulsions nge-fraction ye-volume encane, i-emulsion yokuqala (φ = 0.70) ingahlanjululwa nge-2wt% laponite® powder ku-0.1M NaCl.

Ukuze kulungiselelwe imiqulu emikhulu, i-Hielscher ihlinzeka ngabo bonke I-Lab futhi Ama-ultrasonicators asezimboni amangqamuzana egeleza okhethekile, okuvumela ukusabalalisa / ukuchithwa kokubili, amaconsi ama-powder namafutha abe emulsion ye-nanoscale.

Ithebula elingezansi linikeza isibonakaliso somthamo wokucubungula we-ultrasonicators wethu:

Iqoqwana Ivolumu flow Rate Amadivayisi ezinconyiwe
0.5 kuya ku-1.5mL na I-VialTweeter

Le vidiyo ikhombisa iprosesa le-Hielscher ultrasonic UP400S lilungiselela i-nano-sized uwoyela wemifino-emanzini.

Ukugcizelela Amafutha Yemifino emanzini kusetshenziswa i-UP400S

Ukuhlakazeka kwe-Ultrasonic kwe-Fied Silica: I-Hielscher ultrason homogenizer UP400S isabalalisa i-silica powder ngokushesha futhi kahle zibe zinhlayiya ezingama-nano eyodwa.

Amaqiniso Okufanele Ukwazi

Kungani i-Emulsions engenawo ama-Surfactant?

Imikhiqizo eminingi yokunakekelwa kwesikhumba ibonisa ingxube yezinto ezimbili noma ngaphezulu ezingahambi kahle. Lokhu kusho ukuthi zihambisana nomthetho wesibili we-thermodynamics ngendlela engaguquki. Ukwakha ingxube eqinile kulezi zinto ezingabonakali, ukusetshenziswa kokuqiniswa kuyadingeka ukuze ulungiselele i-emulsion nge-shelf efanelekayo. Ama-surfactant e-Ionic noma angewona ama-ionic avame ukusetshenziswa njengama-emulsifiers. Imikhiqizo yokunakekelwa kwesikhumba, ukusetshenziswa kwesisindo samandla esincane, ama-surfactant amakhulu ajwayelekile abangela ukungahambisani nemikhiqizo yezimonyo ngekhanda elibucayi. Ngaphezu kwalokho, inani elikhulayo labathengi lifuna imikhiqizo yemvelo yemvelo. Imikhiqizo enjalo yanciphisa kakhulu izithako ezisebenzayo, ezithuthukisa isikhumba, futhi zingenakho izithako (isib. Ama-emulsifiers, iphunga njll).
Emulsions free-free / emulsifier mahhala okunye okufisa ukuklama izimonyo ezivamile. Ama-emulsion we-Pickering asekelwe ekusetshenzisweni kwe-emulsifiers ye-biopolymeric noma izinhlayiya eziqinile njengezinyathelo zokudala imikhiqizo eqondile yezimonyo nemikhiqizo emihle yomkhiqizo. I-ultrasonic emulsification iyithuluzi elihle kakhulu lokulungisa i-nano- ne-miniemulsions kanye ne-Pickering emulsions. Ngaphezu kwalokho, i-sonication isetshenziswa kwezinye izinhlelo zokusebenza ngesikhathi kukhiqizwa imikhiqizo yezitho zomzimba ezifana nokuhlakazeka kwezingulube, ukuchithwa kwama-powders, noma ukukhipha izithako ezisebenzayo.

Mayelana ne-Emulsions in Products Cosmetic

I-emulsion iyisimiso sesigaba ezimbili. Izingxenye eziyinhloko ziyisigaba samafutha kanye nesigaba esiphuthumayo.
Isigaba esiphezulu samanzi kanye nanoma yikuphi ukuhlanganiswa kwezinto ezibonakalayo futhi zichitheka, okungenani ngezinga elithile, emanzini.
Isigaba samafutha sinezinto eziwodwa noma ngaphezulu ezinamafutha, noma ezinye izithako ezingezona ezingokoqobo futhi zibonise okungenani ukuxazululwa kwamanye amafutha.

Amafutha-ngaphakathi kwamanzi (o / w): Amaconsi amafutha ahlakazeka emanzini; amafutha abizwa ngokuthi isigaba sangaphakathi noma sahlakazeka namanzi njengengxenye yangaphandle noma eqhubekayo.
I-emulsion yamanzi emanzini (w / o): Amaconsi amanzi asakazeka emafutheni; amanzi yingxenye yangaphakathi noma ehlakazekile kanye namafutha isigaba sangaphandle noma esiqhubekayo.
w / o / w noma o / w / o zibizwa ngokuthi eziyinkimbinkimbi noma emulsions amaningi.
