I kēia manawa,mea hoʻoheheʻe hoʻoheheʻe biodegradableua hoʻohana ʻia no ka hoʻopaʻa paʻa ʻana o nā creams, lipsticks a me nā mea hoʻonaninani ʻē aʻe. Ma muli o ke ʻano o nā mea hoʻonaninani ponoʻī, ʻaʻole pono ia i kahi hiʻohiʻona kūʻokoʻa, akā pono nō hoʻi e loaʻa i kahi ʻeke e hoʻokō i kāna mau hana kūikawā.
ʻO kahi laʻana, ʻo ka instability inherent o nā mea maka cosmetic kokoke i ka meaʻai. No laila, pono e hāʻawi i nā mea pale cosmetic e ʻoi aku ka maikaʻi o ka mālama ʻana i nā waiwai cosmetic. Ma ka ʻaoʻao hoʻokahi, pono e hoʻokaʻawale loa i ka mālamalama a me ka ea, e pale i ka oxidation huahana, a hoʻokaʻawale i ka bacteria a me nā microorganism ʻē aʻe mai ke komo ʻana i ka huahana. Ma ka ʻaoʻao ʻē aʻe, pono ia e pale i nā mea hana i loko o nā mea hoʻonaninani mai ka adsorbed e nā mea hoʻopihapiha a i ʻole ka pane ʻana me lākou i ka wā o ka mālama ʻana, e hoʻopilikia i ka palekana a me ka maikaʻi o nā mea hoʻonaninani.
Eia kekahi, he kiʻekiʻe ka palekana o ka pale cosmetic, no ka mea, i loko o nā mea hoʻohui o ka cosmetic packaging, hiki ke hoʻoheheʻe ʻia kekahi mau mea ʻino e nā mea hoʻonaninani, no laila e hoʻohaumia ʻia nā mea hoʻonaninani.
Biodegradable cosmetic packaging material:
PLA meaLoaʻa i ka hana maikaʻi a me ka biocompatibility, a ʻo ia ka mea nui biodegradable packaging material no nā mea hoʻonaninani. ʻO ka mea PLA he rigidity maikaʻi a me ke kūpaʻa mechanical, hana ia i mea maikaʻi no ka hoʻopili ʻana i nā mea hoʻonaninani paʻa.
ʻO ka Cellulose a me kāna mau mea i loaʻaʻo ia nā polysaccharides maʻamau i hoʻohana ʻia i ka hana ʻana i ka ʻeke a ʻo ia nā polymers kūlohelohe nui loa ma ka honua. Loaʻa i nā ʻāpana monomer glucose i hoʻopili ʻia e nā paʻa glycosidic B-1,4, e hiki ai i nā kaulahao cellulose ke hana i nā paʻa hydrogen interchain ikaika. He kūpono ka paʻi cellulose no ka mālama ʻana i nā mea hoʻonaninani maloʻo non-hygroscopic.
Nā mea mākikohe polysaccharides i haku ʻia me ka amylose a me ka amylopectin, ka mea i loaʻa mai ka cereals, cassava a me ka ʻuala. Loaʻa i nā mea kūʻai ʻia i ka starch kahi hui ʻana o ka starch a me nā polymers ʻē aʻe, e like me ka polyvinyl alcohol a i ʻole polycaprolactone. Ua hoʻohana ʻia kēia mau mea thermoplastic e pili ana i ka starch i ka nui o nā noi ʻoihana a hiki ke hoʻokō i nā kūlana o ka noi extrusion, injection molding, blow molding, puhi kiʻiʻoniʻoni a me ka huʻihuʻi o ka cosmetic packaging. He kūpono no ka non-hygroscopic dry cosmetic packaging.
KitosanLoaʻa iā ia ka mea hiki ke lilo i mea hoʻopili biodegradable no nā mea hoʻonaninani ma muli o kāna hana antimicrobial. ʻO Chitosan kahi polysaccharide cationic i loaʻa mai ka deacetylation o chitin, i loaʻa mai nā pūpū crustacean a i ʻole fungal hyphae. Hiki ke hoʻohana ʻia ʻo Chitosan e like me ka uhi ʻana i nā kiʻiʻoniʻoni PLA e hana i ka ʻeke maʻalahi i biodegradable a me ka antioxidant.
