I loko o nā mea hoʻonaninani, nui nā mea kemika kala ʻole a ʻala ʻole, akā liʻiliʻi nā mea ʻawaʻawa ʻole. I kēia lā wau e hoʻolauna aku iā ʻoehydroxyethyl cellulose, ka mea maʻamau i nā mea hoʻonaninani a i ʻole nā mea e pono ai i kēlā me kēia lā.
Hydroxyethyl Cellulose
ʻIke ʻia hoʻi ʻo (HEC) he keʻokeʻo a ʻulaʻula melemele, ʻaʻala ʻole, fibrous a i ʻole pauda paʻa. Ma muli o kāna mau waiwai maikaʻi o ka mānoanoa, hoʻokuʻu, hoʻopuehu, emulsifying, hoʻopili, hana kiʻiʻoniʻoni, pale i ka wai a me ka hāʻawi ʻana i ka colloid pale, ua hoʻohana nui ʻia ʻo HEC i nā lāʻau lapaʻau a me ka cosmetic.
Nā hiʻohiʻona huahana
1. Hiki ke hoʻoheheʻe ʻia ʻo HEC i ka wai wela a i ʻole ka wai anuanu, kiʻekiʻe ka wela a i ʻole ka paila ʻana me ka ʻole o ka ua, i loaʻa iā ia ka nui o ka solubility a me nā ʻano viscosity, a me ka gelation non-thermal;
2. He non-ionic a hiki ke noho pū me nā polymers wai-soluble, surfactants a me nā paʻakai ma kahi ākea. He mānoanoa colloidal maikaʻi loa ia no nā hoʻonā i loaʻa nā dielectrics kiʻekiʻe;
3. ʻO ka paʻa wai paʻa ʻelua ʻoi aku ka kiʻekiʻe ma mua o ka methyl cellulose, a ʻoi aku ka maikaʻi o ka hoʻoponopono kahe ʻana;
4. Hoʻohālikelike ʻia me ka methyl cellulose i ʻike ʻia a me ka hydroxypropyl methyl cellulose, ʻoi aku ka maikaʻi o ka hoʻopuehu ʻana o HEC, akā ʻoi aku ka ikaika o ka colloid pale.
Roleo HECi nā mea hoʻonaninani
ʻO ke kaumaha o ka molecular i nā mea hoʻonaninani, ʻokoʻa ka nui o nā mea e like me nā synthetics kūlohelohe a me nā synthetics artificial, no laila pono e hoʻohui i kahi solubilizer e hana maikaʻi nā mea hana a pau. ʻO ka solubility a me ka viscosity waiwai o ka hydroxyethyl cellulose piha i ke kuleana, a mālama i kahi ʻano kaulike, i hiki iā ia ke mālama i ke ʻano kumu o nā mea hoʻonaninani i nā kau o ke anuanu a me ka wela. Eia kekahi, loaʻa iā ia nā waiwai moisturizing a loaʻa mau i nā mea hoʻonaninani no nā huahana moisturizing. Hoʻohui ʻia nā masks, toners, etc.
Hanahopena
ʻO ka hydroxyethyl cellulose i hoʻohana ʻia i nā mea hoʻonaninani e like me nā emollients, thickeners, etc. A ua manaʻo ʻia ʻo ia ʻo ka huahana palekana kaiapuni No. 1 e EWG.
