Polysorbate 80 yog ib qho surfactant uas tau siv dav hauv cosmetology. Nws dissolves zoo kawg nkaus hauv dej, stabilizes tsim ua npuas ncauj, thiab kuj softens, soothes thiab moisturizes ntawm daim tawv nqaij. Ua tsaug rau cov yam ntxwv zoo li no, cov tshuaj no nrov heev nrog cov tuam txhab tsim cov tshuaj pleev ib ce.
Hom polysorbates
Muaj 4 hom polysorbates hauv tag nrho:
- polysorbate 20;
- polysorbate 40;
- polybrother 60;
- polysorbate 80, tseem hu ua monooleate.
Nws tsim nyog sau cia tias tag nrho cov npe surfactants yog cov hauv paus chiv keeb nkaus xwb. Lawv tau los ntawm kev ua cov txiv hmab txiv ntoo, noob thiab txiv hmab txiv ntoo. Lub hauv paus yog cov tshuaj sorbitol, uas muaj qab zib me ntsis tom qab.
Tom qab, cov roj ntxiv rau sorbitol. Hom roj nyob ntawm seb qhov twg polysorbate yuav npaj. Piv txwv li, hauv kev tsim cov TWEEN 20 thiab TWEEN 40 tsuas yog txiv maj phaub roj yog siv, TWEEN 60 - xibtes roj, TWEEN 80 - txiv roj roj. Vim yog siv cov khoom xyaw ntuj thiab cov roj, cov surfactants no muaj txiaj ntsig zoo rau lub ntsej muag ntawm daim tawv nqaij, thiab kev sib txuas. Txij li thaum sorbitol muaj cov khoom siv roj-solving, cream thiab tshuaj pleev ib ce raws li TWEEN yog absorbed zoo kawg nkaus rau ntawm daim tawv nqaij.
Yuav ua li cas tus lej polysorbate cuam tshuam rau nws cov khoom
Tag nrho cov npe ntawm polysorbates, suav nrog TWEEN 80 polysorbate, yog cov soluble zoo kawg nkaus hauv ethyl cawv, tab sis nws tsis yog siv los tsim cov tshuaj pleev ib ce. Lawv kuj ua haujlwm zoo nrog cov roj zaub. Cov roj ntxhia thiab lwm cov khoom siv roj av ua kom zoo tsis cuam tshuam nrog surfactants nyob rau hauv ib txoj kev, yog li lawv tsis haum rau kev sib koom siv.
Tus lej polysorbate cuam tshuam qhov twg nws yuav siv. Piv txwv li, polysorbate 20 feem ntau yog siv los ua cov roj yam tseem ceeb.
Polysorbate 80 muaj cov khoom sib txawv me ntsis. Nws yog tshwj xeeb tshaj yog nrov nrog cosmetologists vim hais tias ntawm nws lub peev xwm los tsim ua npuas ncauj. Txawm li cas los xij, ntau dua tus lej polysorbate, ua npuas ncauj ntau dua nws tuaj yeem tsim.
TWIN 80
Ua ntej ntawm tag nrho, cov polysorbate no zoo nrog lwm hom surfactants. Nws ua haujlwm zoo nrog cov roj yam tseem ceeb. Ua hauj lwm raws li ib tug dispersing thiab wetting agent.
Surfactant polysorbate 80 puas tsim kev puas tsuaj lossis tsis? Cov lus nug no feem ntau nug los ntawm cov poj niam cosmetologists. Yuav ua li cas muaj kev nyab xeeb yog siv nyob rau hauv cream thiab tshuaj zawv plaub hau? Qhov tseeb, nws yog xyaum tsis muaj teeb meem rau daim tawv nqaij ntawm lub cev thiab lub ntsej muag, nrog rau cov plaub hau. Qhov tseeb yog tias nws muaj peev xwm pom tau tias soothe ntawm daim tawv nqaij txawm tias thaum nws khaus, thiab nws yuav ua rau cov plaub hau ci, muaj zog thiab ua kom lawv txoj kev loj hlob.
Ntxiv rau, cov khoom no muajcov khoom zoo heev uas pom tseeb txo kev sib txhuam. Qhov peev xwm ntawm cov surfactant tso cai rau cosmetologists siv nws nyob rau hauv yuav luag tag nrho cov khoom, uas, piv txwv li, yog tsim los rau maj mam ntxuav ntawm daim tawv nqaij ntawm lub ntsej muag thiab lub cev.
Qhov twg siv Polysorbate 80
Qhov surfactant no tsuas yog siv rau kev tsim cov khoom kom zoo nkauj. Nws tuaj yeem pom nyob rau hauv yuav luag txhua yam khoom siv tawv nqaij, tab sis feem ntau nws yog siv rau hauv cov roj hydrophilic rau lub ntsej muag, lub cev thiab da dej, cov vuas hydrophilic, cov kua mis ntxuav, qab zib thiab ntsev txhuam.
Tsis tas li ntawd, surfactants nquag siv rau kev npaj tshuaj zawv plaub hau thiab balms. Tshwj xeeb tshaj yog nws tuaj yeem pom hauv cov tshuaj pleev ib ce plaub hau uas tiv thaiv plaub hau.
Effervescent da dej foob pob kuj tau tsim los ntawm TWEEN 80. Interestingly, ntau surfactants nyob rau hauv lub foob pob, ntev lawv khaws lawv effervescent zog.
Lub ntsej muag tonics, huab cua fresheners (dej-raws li nkaus xwb), deodorants tsis siv cawv, nrog rau cov tshuaj tsuag lub cev thiab lwm yam khoom siv tshuaj pleev ib ce uas tsis tas yuav siv cov cawv cawv yog tsim los ntawm TWEEN. Nws yog ib qho tsim nyog yuav tsum nco ntsoov tias cawv muaj qhov cuam tshuam rau cov txiaj ntsig zoo ntawm TWEEN 80, thiab tseem ua rau nws puas tsuaj. Yog li ntawd, nws siv nrog cawv yog qhov tsis lees txais.
TWEEN 80. Cov lus qhia siv
Txhua surfactant yuav tsum tau siv kom raug, suav nrog polysorbate 80. Nws siv hauv emulsions uas muaj roj thiab dej muajstabilizing nyhuv ntawm cov muaj pes tsawg leeg. Cosmetologists pom zoo kom siv no surfactant nyob rau hauv nws daim ntawv ntshiab rau kev npaj, piv txwv li, ib tug cleansing kua mis rau lub ntsej muag. Cov khoom zoo li no yuav dhau los ua qhov zoo.
TWEEN 80 yog siv nyob rau hauv ntau ntawm 1% mus rau 50%. Feem ntau, ntau npaum li cas ntawm 1% mus rau 5% surfactant yog siv, tab sis nws tag nrho yog nyob ntawm kev tsim cov khoom tsim. Nws yog tsim nyog sau cia tias qhov siab dua ntawm TWEEN 80 feem ntau tsuas yog siv rau kev siv cov khoom lag luam. Qhov no surfactant tuaj yeem ua kom tuab cov khoom kawg. Cov khoom ua kua feem ntau yog tau siv 1% ntawm cov muaj pes tsawg leeg. Yog hais tias nyob rau hauv lub chaw tsim khoom ntawm cov tshuaj pleev ib ce cov khoom uas muaj ib tug ntau dua concentration tau siv, ces nyob rau hauv cov ntaub ntawv no cov mis nyuj los yog zawv plaub hau yuav thicker. Qhov no yuav tsum tau coj mus rau hauv tus account kom yooj yim ntawm kev siv.
Yog tias nws tsim nyog rau yaj cov roj yam tseem ceeb, ces siv ib feem ntawm polysorbate thiab 0.5 feem ntawm cov roj. Qee zaum koj tuaj yeem nce cov roj rau ib chav.
