He aha te Hydroxyethyl Cellulose?

Ko te Hydroxyethyl cellulose he ma ki te kowhai marama he kiko, he paura totoka, he kore-paitini, he reka, he ngawari te whakarewa ki te wai. Kare e wetewete i roto i nga whakarewa waro whanui. Kei a ia nga ahuatanga o te matotoru, te whakatarewa, te honohono, te whakaemulsifying, te whakamarara, me te pupuri i te makuku. Ka taea te whakarite etahi otinga he rereke nga awhe pokey. He tino pai te tote i roto i nga electrolytes. Ko te Hydroxyethyl cellulose he paura ma, he kowhai marama ranei kahore he kakara, he reka, he ngawari te rere. He wairewa i roto i te wai matao me te wai wera, a, i te nuinga o nga wa karekau i roto i te nuinga o nga whakarewa pararopi. He iti te huri o te pokey ina ko te uara pH kei roto i te awhe o te 2-12, engari ka heke te pokey ki tua atu i tenei awhe.

Taupānga

1. Ko te Hydroxyethyl cellulose (HEC) he ether cellulose wairewa kore-ionic me te pai o te matotoru, te aukati, te marara, te emulsification, te adhesion, te hanga kiriata, te whakamarumaru makuku me nga taonga colloid tiaki. Na te ahurei o te tinana me te matū, ka whakamahia te HEC i roto i te maha o nga mara, tae atu ki te tango hinu, te paninga, te hanga, te kai rongoa, te kakano, te hanga pepa me te polymerization.
2. I roto i te mara ho'oraa, i tua atu ki te he mātotoru me te māngai tiaki, hydroxyethyl cellulose hoki te pānga o moisturizing, hydrating, anti-pakeke, horoi kiri, me te tango melanin. He pai mo te hanga i nga pata kanohi, nga rehu nasal, nga rongoa a-waha, me etahi atu. Ka taea e ia te whakanui ake i te kaha o te tarukino, te whakapai ake i te tere o te whakauru o te tarukino ki roto i te tinana, me te whakanui ake i te pumau o te tarukino hei aukati i te pirau o te tarukino me te waikura.
3. I roto i te ahumahi whakapaipai, kei te whakamahia nuitia te HEC i roto i te hanga shampoo, conditioner, cream, lotion me etahi atu hua. Ka taea e ia te whakatika i te pokey me te kakano o nga mea whakapaipai kia ngawari ai te tono me te mimiti. I te wa ano, ka whai hua ano te whakamakuku, ka taea te kati i te makuku, ka aukati i te maroke o te kiri me te pakaru.
4. I tua atu, ko te hydroxyethyl cellulose te nuinga o te whakamahinga hei pupuhi, te tae me te tiaki i roto i te ahumahi kai, ka taea te whakanui ake i te viscosity me te kakano o te kai me te whakapai ake i te reka me te kounga o te kai. Ka taea hoki te whakamahi hei emulsifier me te whakapumau hei aukati i te stratification kai me te rerenga.
5. Mo te waikawa me te kawakore o te hydroxyethyl cellulose, i te mea no roto i te katote cellulose ether class, ehara i te waikawa, i te kawakore ranei. Ko tana tātai matū ko (C2H6O2)n, he pai te whakarewatanga, te pumau me te matotoru, me te whai waahi nui ki nga momo waahanga tono.
