Hydroxyethylcellulose vs carbomer

ʻO Hydroxyethylcellulose (HEC) a me ka carbomer ʻelua mau polymers maʻamau i ka ʻoihana mālama pilikino. Loaʻa iā lākou nā ʻano hana kemika a me nā waiwai, i kūpono iā lākou no nā noi like ʻole.

ʻO HEC he polimer kūlohelohe maoli i loaʻa mai ka cellulose. Hoʻohana maʻamau ia e like me ka mānoanoa, emulsifier, a me ka stabilizer i nā huahana mālama pilikino e like me nā shampoos, conditioners, a me nā holoi kino. ʻIke ʻia ʻo HEC no kona kūlike kiʻekiʻe me nā mea ʻē aʻe a me kona hiki ke hāʻawi i kahi ʻano maʻalahi a me ka momona i nā formulations. Ua ʻike ʻia nō hoʻi no kona moʻokalaleo maikaʻi a me ka haʻahaʻa haʻahaʻa.

ʻO Carbomer, ma ka ʻaoʻao ʻē aʻe, he synthetic, kiʻekiʻe molecular weight polymer i hoʻohana mau ʻia ma ke ʻano he mānoanoa i nā huahana mālama pilikino e like me nā gels a me nā lotions. He mea maikaʻi loa ia i ka mānoanoa a me ka hoʻopaʻa ʻana i nā formulations, a hiki ke hāʻawi i kahi kiʻekiʻe o ka mālamalama a me ka hoʻokuʻu ʻana i ka huahana i hoʻopau ʻia. ʻIke ʻia ʻo Carbomer no kāna kaohi viscosity maikaʻi loa a me ka hiki ke hoʻonui i ka laha o nā huahana.

ʻO kekahi o nā ʻokoʻa nui ma waena o HEC a me ka carbomer ʻo ko lākou hiki ke hoʻoheheʻe wai. He mea hiki ke hoʻoheheʻe ʻia ka HEC i ka wai, ʻoiai ʻo ka carbomer e koi i ka neutralization me kahi ʻano alkaline e like me ka triethanolamine a i ʻole ka sodium hydroxide e lilo i hydrated a mānoanoa. Hoʻohui ʻia, ʻike ʻia ʻo HEC no kona haʻahaʻa haʻahaʻa i ka pH a me nā loli wela, ʻoiai hiki ke hoʻopili ʻia ka carbomer e nā loli i ka pH a me ka mahana.

I ka hōʻuluʻulu ʻana, ʻo HEC a me ka carbomer ʻelua mau ʻano polymers me nā waiwai kūʻokoʻa a me nā noi. ʻO HEC kahi polymer kūlohelohe, wai-soluble i hoʻohana mau ʻia e like me ka mānoanoa a me ka emulsifier, aʻo ka carbomer he synthetic, kiʻekiʻe molecular weight polymer i kūpono loa i ka mānoanoa a me ka hoʻopaʻa ʻana i nā formulations. ʻO ke koho o ka polymer e pili ana i nā pono kikoʻī a me nā waiwai o ka hoʻokumu ʻana.
