Ko hydroxypropyl cellulose ine chepfu here?

Hydroxypropyl cellulose (HPC) isiri-chepfu, inoora, uye inonyungudika nemvura polima yakabva muselulosi.Inoshandiswa mumhando dzakasiyana dzezvigadzirwa, zvinosanganisira mishonga, cosmetics, chikafu, uye zvigadzirwa zvemaindasitiri.HPC inowanzoonekwa seyakachengeteka kuti ishandiswe nevanhu uye inotenderwa kushandiswa muchikafu uye zvigadzirwa zvekuzora neUS Food and Drug Administration (FDA).

HPC chinhu chisina chepfu, chisingagumbure, uye chisiri allergenic.Iyo haifungidzirwe secarcinogen, mutagen, kana teratogen, uye haikonzeri chero yakaipa mhedzisiro muvanhu kana mhuka kana ichishandiswa zvinoenderana neinokurudzirwa dosage.HPC hainawo kuzivikanwa kuve inobereka kana kukura muchetura.

Pamusoro pezvo, HPC haizivikanwe kuve njodzi yezvakatipoteredza.Haisi kunzi inoramba ichienderera, bioaccumulative, kana chepfu (PBT) kana kuti inoramba ichienderera uye yakanyanya bioaccumulative (vPvB).HPC haina zvakare kunyorwa sechinhu chine njodzi kana kusvibisa pasi peClean Air Act kana iyo Yakachena Mvura Act.

HPC inoshandiswa seyakakora, emulsifier, uye stabilizer mune zvizorwa maumbirwo akadai shampoos, conditioners, uye lotions.

Kunyangwe iyo isiri-chepfu hunhu, HPC inofanirwa kuramba ichibatwa nehanya.Kunwa huwandu hwakawanda hweHPC kunogona kukonzera kutsamwa kwepamuviri, kusvotwa, kurutsa, uye manyoka.Inhalation yeHPC huruva inogona kukonzera kushatirwa kwemhino, huro, uye mapapu.Kutarisana neziso neHPC kunogona kukonzera kushatirwa uye kutsvuka.

Mukupedzisa, hydroxypropyl cellulose inowanzoonekwa seyakachengeteka kudyiwa nevanhu uye inotenderwa kushandiswa muzvigadzirwa zvekudya neFDA.Iyo haifungidzirwe secarcinogen, mutagen, kana teratogen, uye haikonzeri chero yakaipa mhedzisiro muvanhu kana mhuka kana ichishandiswa zvinoenderana neinokurudzirwa dosage.HPC haizivikanwe zvakare kuve njodzi yezvakatipoteredza uye haina kunyorwa sechinhu chine njodzi kana kusvibisa pasi peClean Air Act kana iyo Yakachena Mvura Act.Zvisinei, kunwa kwehuwandu hweHPC kunogona kukonzera kutsamwa kwepamuviri, kushungurudza, kurutsa, uye manyoka, nepo inhalation yeHPC guruva inogona kukonzera kushatirwa kwemhino, huro, nemapapu.Kutarisana neziso neHPC kunogona kukonzera kushatirwa uye kutsvuka.
