Hydroxyethyl cellulose vs xanthan chingamu

Hydroxyethyl cellulose (HEC) uye xanthan chingamu marudzi maviri akasiyana ezvikobvu anowanzoshandiswa mumaindasitiri akasiyana siyana, kusanganisira maindasitiri ezvekudya, emishonga, uye zvekuzora. Ose ari maviri aya makobvu mapolymer anonyungudika nemvura anogona kuwedzera viscosity uye kugadzikana kwemhinduro. Nekudaro, ivo vanosiyana maererano nemidziyo yavo uye mashandisirwo avanoshandiswa. Muchikamu chino, tichafananidza hydroxyethyl cellulose uye xanthan gum, tichikurukura nezvezvivakwa zvavo, mabasa, uye mashandisirwo.

Hydroxyethyl Cellulose (HEC)

Hydroxyethyl cellulose is nonionic cellulose ether inotorwa kubva mu cellulose kuburikidza nekuwedzera kwe hydroxyethyl mapoka kumusana we cellulose. HEC inowanzoshandiswa seyakakora, inosimbisa, uye emulsifier mumaindasitiri akasiyana siyana, kusanganisira chikafu, mishonga, uye cosmetic industries.

HEC ine mabhenefiti akati wandei pamusoro pemamwe marudzi emakobvu. Iine high viscosity uye inogona kuumba mhinduro dzakajeka pakadzikadzika. Iyo zvakare yakanyanya kunyungudika mumvura uye inoenderana nehuwandu hwakawanda hwezvimwe zvinhu. Uyezve, HEC inogona kuvandudza kugadzikana kwe emulsions uye kumiswa, zvichiita kuti zvive zvakakosha mune zvakasiyana-siyana zvekugadzirisa.

HEC inowanzoshandiswa muindasitiri yezvizorwa kuvandudza magadzirirwo uye kuenderana kwezvinhu zvekuchengeta zvega, senge shampoos, conditioners, lotions, uye makirimu. Inogona zvakare kuita seanomisa mumiriri, emulsifier, uye binder. HEC inonyanya kukosha muzvigadzirwa zvekuchengetedza bvudzi, sezvo inogona kupa chimiro chakatsetseka uye chinotapira chinowedzera kupararira kwechigadzirwa.

Xanthan Gum

Xanthan chingamu i polysaccharide inogadzirwa nekuvirisa kweXanthomonas campestris bhakitiriya. Iyo inowanzoshandiswa seyakakora uye inodzikamisa mune chikafu, mishonga, uye cosmetic maindasitiri. Xanthan chingamu ndeye yakakwira molecular huremu polysaccharide, iyo inoipa iyo kukora kwayo.

Xanthan chingamu ine zvakati wandei zvakanakira seyakakora. Iine high viscosity uye inogona kuumba gels pane yakaderera concentrations. Iyo zvakare inonyungudika zvakanyanya mumvura uye inogona kumirisana neyakasiyana tembiricha uye pH mazinga. Uyezve, xanthan gum inogona kuvandudza kugadzikana kwe emulsions uye suspensions, zvichiita kuti zvive zvakakosha mumhando dzakasiyana-siyana dzekugadzirisa.

Xanthan chingamu inowanzoshandiswa muindasitiri yechikafu seyakakora uye inodzikamisa muzvigadzirwa zvakasiyana siyana, zvinosanganisira mapfekero esalad, sosi, uye zvigadzirwa zvekubheka. Inoshandiswawo muindasitiri yemishonga semumiriri wekumisa uye muindasitiri yezvizorwa seyakakora uye inodzikamisa mumhando dzakasiyana dzezvigadzirwa zvekuchengeta munhu, senge lotions nemafuta.

Kuenzanisa

HEC uye xanthan chingamu zvakasiyana munzira dzakawanda. Imwe misiyano mikuru ndiko kunobva iyo polymer. HEC inotorwa kubva ku cellulose, yakasikwa polymer inowanikwa mumiti, nepo xanthan chingamu inogadzirwa nekuvirisa kwebhakitiriya. Musiyano uyu mune sosi unogona kukanganisa zvivakwa uye mashandisirwo eaya maviri thickeners.

Mumwe mutsauko pakati peHEC uye xanthan chingamu ndiko solubility yavo. HEC inonyanya kunyungudika mumvura uye inogona kuumba mhinduro dzakajeka pakadzikadzika. Xanthan chingamu zvakare inonyungudika zvakanyanya mumvura, asi inogona kuumba gels pane yakaderera. Uyu mutsauko mukunyungudika unogona kukanganisa magadzirirwo uye kuenderana kwemagadzirirwo ane aya makobvu.

Iyo viscosity yeHEC uye xanthan gum zvakare inosiyana. HEC ine viscosity yakakwirira, iyo inoita kuti ive yakakosha seyakakura mumhando dzakasiyana-siyana dzekugadzirisa. Xanthan gum ine yakaderera viscosity pane HEC, asi inogona kuramba ichigadzira gels payakadzika.
