HEC (Hydroxyethyl Cellulose) bụ ngwakọta polymer na-agbaze mmiri nke a na-ejikarị na kemịkalụ kwa ụbọchị. N'ihi ịdị mma ya, nkwusioru, emulsification, imepụta ihe nkiri na nkwụsi ike, HEC na-arụ ọrụ dị mkpa n'ọtụtụ ngwaahịa kemịkalụ kwa ụbọchị.
1. Njirimara nke HEC
HEC bụ polymer na-abụghị ionic gbanwere site na cellulose, nke a na-eme site na iwebata ìgwè hydroxyethyl n'ime agbụ molekul cellulose. Isi njirimara ya bụ ndị a:
Mmiri solubility: HEC nwere ezigbo mmiri solubility ma nwee ike ịgbaze ngwa ngwa na mmiri oyi ma ọ bụ ọkụ. Uru pH adịghị emetụta solubility ya ma nwee ike ime mgbanwe.
Mmetụta dị arọ: HEC nwere ike ịbawanye viscosity nke oge mmiri, si otú a na-egwu mmetụta na-ekpo ọkụ na ngwaahịa ahụ. Mmetụta ya na-eme ka ọ sie ike na-ejikọta ya na arọ molekụla ya. Ka ibu molekụla ahụ buru ibu, ka ihe onwunwe na-esiwanye ike.
Emulsification na nkwụsi ike: Dị ka emulsifier na stabilizer, HEC nwere ike ịmepụta ihe nkiri nchebe na interface n'etiti mmiri na mmanụ, mee ka nkwụsi ike nke emulsion dịkwuo elu, ma gbochie nkewa nke oge.
Mmetụta nkwusioru na mgbasa ozi: HEC nwere ike kwụsịtụ ma gbasasịa ihe ndị siri ike ka ha wee kesaa ya n'ụzọ zuru oke na mmiri mmiri, ọ dịkwa mma maka iji ngwaahịa nwere ntụ ntụ ma ọ bụ ihe granular.
Biocompatibility na nchekwa: A na-enweta HEC site na cellulose eke, ọ dị mma, adịghị egbu egbu, na nke na-adịghị ewe iwe na akpụkpọ ahụ, ọ dịkwa mma maka nlekọta onwe ya na ihe ịchọ mma.
2. Ngwa nke HEC na ngwaahịa kemịkalụ kwa ụbọchị
Ncha na ncha ntutu
A na-ejikarị HEC eme ihe dị ka ihe na-eme ka ọ sie ike ma na-akwụsịtụ n'ihe na-ehicha ngwaahịa dị ka ncha na shampoos. Ngwongwo ya siri ike na-enyere ngwaahịa aka ịzụlite udidi dabara adaba ma kwalite ahụmịhe ndị ahịa. Ịtinye HEC na ncha ntutu nwere ike inye ya ọdịdị silky nke na-agaghị agba ọsọ ngwa ngwa. N'otu oge ahụ, mmetụta nkwusioru nke HEC nwere ike inyere ihe ndị na-arụ ọrụ (dị ka mmanụ silicone, wdg) na shampoo na-ekesa nke ọma, zere stratification, ma hụ na ọ dị irè.
Ngwaahịa nlekọta anụ ahụ
N'ihe gbasara ngwaahịa nlekọta anụ ahụ, a na-eji HEC eme ihe dị ka ihe na-eme ka ọkpụkpụ, ihe na-eme ka mmiri na-emepụta ihe na ihe nkiri. HEC nwere ike ịmepụta ihe nkiri dị mkpa n'elu akpụkpọ ahụ iji mee ka mmiri dị nro na igbachi mmiri. Ihe ndị na-emepụta ihe nkiri ya na-ekwe ka ngwaahịa nlekọta anụ ahụ na-emepụta ihe nchebe dị mma na akpụkpọ ahụ mgbe etinyere ya, na-enyere aka belata evaporation mmiri. Tụkwasị na nke a, a pụkwara iji HEC mee ihe dị ka ihe nkwụnye aka iji nyere mmanụ na mmiri mmiri dị na ngwaahịa nlekọta anụ ahụ aka ịdị n'otu ma mee ka ha dị n'otu ruo ogologo oge.
ihe ntacha eze
Na ntacha eze, a na-eji HEC eme ihe dị ka ihe na-eme ka ọkpụkpụ na stabilizer na-enye ihe ntanye eze ka ọ bụrụ nhazi nke ọma, na-eme ka ọ dị mfe ịpịpụ na iji. Ikike nkwusioru nke HEC nwekwara ike inye aka gbasasịa ihe ndị na-emerụ ahụ na ntanye eze, na-ahụ na a na-ekesa ihe ndị na-eme ka ọkpụkpụ na-eme ka ọ bụrụ nke ọma na mado, si otú ahụ na-enweta nsonaazụ nhicha dị mma. Tụkwasị na nke ahụ, HEC adịghị akpasu iwe n'ọnụ ma ọ gaghị emetụta uto nke ncha eze, si otú ahụ na-ezute ụkpụrụ eji eme ihe dị mma.
Ngwaahịa etemeete
A na-eji HEC dị ka onye na-emepụta ihe na-emepụta ihe nkiri na ngwaahịa etemeete, karịsịa mascara, eyeliner, na ntọala. HEC nwere ike ịbawanye viscosity nke ngwaahịa ịchọ mma, na-eme ka ọdịdị ha dịkwuo mfe ịchịkwa ma na-enyere aka melite arụmọrụ ngwaahịa ahụ. Ihe na-emepụta ihe nkiri na-eme ka ọ dịkwuo mfe maka ngwaahịa ahụ iji jide n'aka na akpụkpọ ahụ ma ọ bụ ntutu isi, na-agbatị ogologo oge nke etemeete. Tụkwasị na nke ahụ, ihe ndị na-abụghị ionic nke HEC na-eme ka ọ ghara ịdaba na ihe ndị metụtara gburugburu ebe obibi (dị ka okpomọkụ na iru mmiri), na-eme ka ngwaahịa etemeete dịkwuo mma.
Ngwaahịa ihicha ụlọ na-asa ákwà
N'ime ngwaahịa nhicha ụlọ dị ka ncha efere na ndị na-ehicha ala, a na-ejikarị HEC eme ihe maka ịgbatị na nkwụsi ike iji hụ na ngwaahịa ndị ahụ nwere mmiri mmiri kwesịrị ekwesị na ahụmahụ ojiji. Karịsịa n'ime ihe ndị a na-etinye uche, mmetụta nke HEC na-eme ka ọ dịkwuo mma na-enyere aka melite ogologo oge ma belata usoro onunu ogwu. Mmetụta nkwusioru na-ekesa ihe ndị na-arụ ọrụ na ihe dị ọcha nke ọma, na-eme ka nsonaazụ nhicha na-agbanwe agbanwe.
3. Usoro mmepe nke HEC na ngwaahịa kemịkalụ kwa ụbọchị
Green na mmepe na-adigide: Ihe ndị ahịa chọrọ maka nchekwa gburugburu ebe obibi na nkwado nke ngwaahịa kemịkal kwa ụbọchị na-eji nwayọọ nwayọọ na-abawanye. Dị ka ihe na-emepụta cellulose sitere n'okike, HEC sitere na akụ osisi ma nwee ike biodegradability, nke kwekọrọ na usoro nchebe gburugburu ebe obibi. N'ọdịnihu, a na-atụ anya HEC ga-enwetakwu ewu ewu, karịsịa na ngwaahịa kemịkalụ na eke kwa ụbọchị.
Nhazi na ọtụtụ ọrụ: HEC nwere ike ịrụ ọrụ synergistically na ndị ọzọ thickeners, moisturizers, emulsifiers, wdg iji gboo a dịgasị iche iche nke mkpa na-enye ngwaahịa ike ọrụ. N'ọdịnihu, HEC nwere ike jikọta ya na ihe ọhụrụ ndị ọzọ iji nyere aka ịmepụta ọtụtụ ngwaahịa kemịkal na-arụ ọrụ kwa ụbọchị, dị ka nchebe anyanwụ, mmiri mmiri, ịcha ọcha na ngwaahịa ndị ọzọ niile.
Ngwa dị mma na nke dị ọnụ ala: Iji gboo mkpa njikwa ọnụ ahịa nke ndị na-emepụta ngwaahịa kemịkalụ kwa ụbọchị, HEC nwere ike ịpụta na ngwa ndị na-arụ ọrụ nke ọma n'ọdịniihu, dị ka site na mgbanwe mkpụrụ ndụ ma ọ bụ iwebata ihe enyemaka ndị ọzọ iji meziwanye arụmọrụ ya. .

A na-eji HEC eme ihe na ngwaahịa kemịkalụ kwa ụbọchị dị ka ncha, ngwaahịa na-ahụ maka anụ ahụ, ncha eze na etemeete n'ihi njiri mara mma ya, imepụta ihe nkiri na ihe na-eme ka ọ kwụsie ike. Ọ na-arụ ọrụ dị mkpa n'ịkwalite udidi ngwaahịa, melite ahụmịhe onye ọrụ, na ịkwalite nkwụsi ike ngwaahịa. mmetụta. Site na mmepe nke nchebe gburugburu ebe obibi akwụkwọ ndụ akwụkwọ ndụ na ọtụtụ ọrụ na-arụ ọrụ, atụmanya ngwa nke HEC ga-abawanye. N'ọdịnihu, HEC ga-eweta ihe ngwọta dị mma, nchekwa na gburugburu ebe obibi maka ngwaahịa kemịkalụ kwa ụbọchị site na mmepụta teknụzụ na-aga n'ihu.
