Nā Kumu e Hoʻopilikia ana i ka Hana o nā Kānana UV

ʻOkoʻa loa nā ʻano hana o ka titanium dioxide a me ka zinc oxide ma muli o nā ʻano pākahi o ka papa kikoʻī i hoʻohana ʻia, e laʻa. ka uhi ʻana, ke ʻano kino (pauka, hoʻopuehu ʻaila, hoʻopuehu wai).Pono nā mea hoʻohana e kūkākūkā me nā mea hoʻolako ma mua o ke koho ʻana i ka māka kūpono loa e hoʻokō ai i kā lākou mau pahuhopu hana i kā lākou ʻōnaehana hoʻohui.

Hoʻopili ʻia ka pono o nā kānana UV organik hiki ke hoʻoheheʻe ʻia i ka ʻaila e ko lākou hiki ke hoʻoheheʻe ʻia i loko o nā emollients i hoʻohana ʻia i ka hoʻohuihui ʻana. Ma keʻano laulā, ʻo nā emollients polar nā mea hoʻoheheʻe maikaʻi loa no nā kānana organik.

Hoʻopilikia nui ʻia ka hana o nā kānana UV āpau e ke ʻano rheological o ka hoʻohuihui a me kona hiki ke hana i kahi kiʻiʻoniʻoni like a kūlike ma ka ʻili. ʻO ka hoʻohana ʻana i nā mea hana kiʻiʻoniʻoni kūpono a me nā mea hoʻohui rheological e kōkua pinepine i ka hoʻomaikaʻi ʻana i ka pono o nā kānana.
ʻO ka hui pū ʻana o nā kānana UV (synergies)

Nui nā hui pū ʻana o nā kānana UV e hōʻike ana i nā synergies. ʻO nā hopena synergistic maikaʻi loa e hoʻokō pinepine ʻia ma ka hoʻohui ʻana i nā kānana e hoʻokō kekahi i kekahi ma kekahi ʻano, no ka laʻana:-
• Hoʻohui i nā kānana hoʻoheheʻe ʻia i ka ʻaila (a i ʻole ka ʻaila i hoʻopuehu ʻia) me nā kānana hoʻoheheʻe ʻia i ka wai (a i ʻole ka wai i hoʻopuehu ʻia)
• Hoʻohui i nā kānana UVA me nā kānana UVB
• Hoʻohui i nā kānana inorganic me nā kānana organik

Aia kekahi mau hui pū ʻana e hiki ke loaʻa nā pono ʻē aʻe, no ka laʻana, ua ʻike maopopo ʻia he kōkua ka octocrylene i ka photo-stabilize i kekahi mau kānana photo-labile e like me ka butyl methoxydibenzoylmethane.

Eia nō naʻe, pono e noʻonoʻo mau i ka waiwai noʻeau ma kēia wahi. Nui nā palapala Sila Nui e uhi ana i nā hui pū ʻana o nā kānana UV a ua ʻōlelo ʻia nā mea hoʻohui e nānā mau i ka hui pū ʻana a lākou e manaʻo ai e hoʻohana ʻaʻole e hōʻino i nā palapala Sila Nui ʻaoʻao ʻekolu.

E koho i ka kānana UV kūpono no kāu ʻano hoʻonaninani

E kōkua nā ʻanuʻu aʻe iā ʻoe e koho i nā kānana UV kūpono no kāu ʻano hoʻonani:
1. E hoʻonohonoho i nā pahuhopu maopopo no ka hana, nā waiwai nani a me nā koi i manaʻo ʻia no ka hoʻokumu ʻana.
2. E nānā i nā kānana i ʻae ʻia no ka mākeke i manaʻo ʻia.
3. Inā he chassis formulation kikoʻī kāu e makemake ai e hoʻohana, e noʻonoʻo i nā kānana e kūpono me kēlā chassis. Eia naʻe inā hiki, ʻoi aku ka maikaʻi o ke koho mua ʻana i nā kānana a hoʻolālā i ka formulation a puni lākou. He ʻoiaʻiʻo loa kēia me nā kānana inorganic a particulate organic paha.
4. E hoʻohana i nā ʻōlelo aʻoaʻo mai nā mea hoʻolako a/a i ʻole nā ​​​​mea hana wānana e like me ka BASF Sunscreen Simulator e ʻike i nā hui pū ʻana e pono aie hoʻokō i ka SPF i manaʻo ʻiaa me nā pahuhopu UVA.

Hiki ke hoʻāʻo ʻia kēia mau hui pū ʻana i loko o nā ʻano hana. He mea pono nā ʻano hoʻāʻo In-vitro SPF a me UVA i kēia pae e hōʻike i nā hui pū ʻana e hāʻawi i nā hopena maikaʻi loa ma ke ʻano o ka hana - hiki ke hōʻiliʻili ʻia ka ʻike hou aku e pili ana i ka noi, ka wehewehe ʻana a me nā palena o kēia mau hoʻāʻo me ka papa hana hoʻomaʻamaʻa SpecialChem e-training:UVA/SPF: Ke hoʻomaikaʻi nei i kāu mau protocols hoʻāʻo

ʻO nā hopena hoʻāʻo, me nā hopena o nā hoʻāʻo a me nā loiloi ʻē aʻe (e like me ke kūpaʻa, ka pono mālama, ka ʻili), e hiki ai i ka mea hana ke koho i ke koho maikaʻi loa a alakaʻi pū i ka hoʻomohala hou ʻana o ke (nā) ʻano hana.
