Parizvino,biodegradable cosmetic packaging zvinhuyakashandiswa pakurongedza kwakasimba kwemafuta, lipsticks uye zvimwe zvekuzora. Nekuda kwekusarudzika kwezvizoro pachayo, haingodi chete kuve neyakasarudzika chitarisiko, asi inodawo kuve nepakiti inosangana nemabasa ayo akakosha.
Semuyenzaniso, kusagadzikana kwemukati mecosmetic raw materials iri pedyo neiyo yechikafu. Naizvozvo, cosmetic packaging inoda kupa zvakanyanya kushanda zvipingamupinyi zvivakwa uchichengetedza zvizorwa. Kune rimwe divi, zvinodikanwa kuparadzanisa zvachose chiedza nemhepo, kudzivirira chigadzirwa oxidation, uye kupatsanura mabhakitiriya uye mamwe ma microorganisms kubva pakupinda muchigadzirwa. Nekune rumwe rutivi, inofanirawo kudzivirira iyo inoshanda zvinoshandiswa muzvizoro kubva pakushambadza nekurongedza zvinhu kana kuita nazvo panguva yekuchengetedza, izvo zvinokanganisa kuchengetedzwa uye kunaka kwezvizoro.
Pamusoro pezvo, kurongedza kwecosmetic kune yakakwira biological chengetedzo zvinodiwa, nekuti mune zvekuwedzera zvecosmetic packaging, zvimwe zvinhu zvinokuvadza zvinogona kunyungudika nezvizora, nekudaro zvichikonzera kuti zvizorwa zvisvibiswa.
Biodegradable cosmetic packaging zvinhu:
PLA zvinhuine yakanaka processability uye biocompatibility, uye parizvino ndiyo huru biodegradable kurongedza zvinhu zvezvizoro. Iyo PLA zvinhu zvine kunaka kuomarara uye kusimba kwemechani, zvichiita kuti ive yakanaka zvinhu zvekuomarara zvekushongedza kurongedza.
Cellulose uye zvinobva kwayondiwo anonyanya kushandiswa mapolysaccharides anoshandiswa mukugadzirwa kwekutakura uye ndiwo akanyanya kuwanda mapolymers epasi. Inosanganisira glucose monomer units akabatanidzwa pamwe chete neB-1,4 glycosidic bond, izvo zvinoita kuti maketani e cellulose agadzire yakasimba interchain hydrogen bond. Cellulose packaging yakakodzera kuchengetwa kweasina-hygroscopic yakaoma zvizoro.
Starch zvinhumapolysaccharides anoumbwa neamylose uye amylopectin, anonyanya kutorwa kubva muzviyo, mufarinya uye mbatatisi. Zvekutengesera zvinowanika starch-based zvinhu zvinosanganisira musanganiswa westarch nemamwe mapolymer, akadai sepolyvinyl doro kana polycaprolactone. Aya mastarch-based thermoplastic zvinhu akashandiswa mune dzakasiyana siyana maindasitiri ekushandisa uye anogona kusangana nemamiriro e extrusion application, jekiseni kuumba, kuvhuvhuta, kuvhuvhuta kwemafirimu uye kupupa kwepakeji yekuzora. Inokodzera kune isiri-hygroscopic yakaoma cosmetic packaging.
Chitosanine hunyanzvi hwekurongedza zvinhu zvezvizoro zvebiodegradable nekuda kwekuita kwayo kweantimicrobial. Chitosan is cationic polysaccharide inotorwa kubva ku deacetylation yechitin, iyo inotorwa kubva kune crustacean shells kana fungal hyphae. Chitosan inogona kushandiswa seyekupfekedza pamafirimu ePLA kugadzira kurongedza kunochinjika izvo zviri zviviri biodegradable uye antioxidant.
