Nā kānana UV inorganic Nā ʻano kemika

Titanium Dioxide
• ʻO kahi kānana UVB ma mua, akā hāʻawi kekahi mau māka i ka pale UVA maikaʻi
• Loaʻa nā māka like ʻole me nā ʻāpana ʻokoʻa like ʻole, nā uhi etc.
• Hāʻule ka hapa nui o nā māka i ke aupuni o nā nanoparticles
• ʻO nā ʻāpana liʻiliʻi liʻiliʻi loa i ka ʻili akā hāʻawi i ka pale UVA liʻiliʻi; ʻOi aku ka nui o ka pale UVA akā ʻoi aku ka keʻokeʻo ma ka ʻili

Zinc Oxide
• ʻO kahi kānana UVA mua; ʻoi aku ka maikaʻi o ka SPF ma mua o TiO2, akā hāʻawi i ka pale ʻoi aku ka maikaʻi ma mua o TiO2 ma ka ʻāpana "UVA-I" lōʻihi.
• Loaʻa nā māka like ʻole me nā ʻāpana ʻokoʻa like ʻole, nā uhi etc.
• Hāʻule ka hapa nui o nā māka i ke aupuni o nā nanoparticles

Hana / Kemika matrix

Ka helu mai -5 a +5:
-5: hopena maikaʻi ʻole nui | 0: ʻaʻohe hopena | +5: hopena maikaʻi nui
(E hoʻomaopopo: no ke kumukūʻai a me ka hoʻomaʻemaʻe ʻana, ʻo ka "hopena maikaʻi ʻole" ʻo ia hoʻi ke hoʻonui ʻia ke kumukūʻai a i ʻole ke keʻokeʻo.)

Nā mea e pili ana i ka hana o nā kānana UV

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

Hoʻopili ʻia ka maikaʻi o nā kānana UV organik hiki ke hoʻoheheʻe ʻia e ko lākou solubility i nā emollients i hoʻohana ʻia i ka hana. ʻO ka maʻamau, ʻo nā emollient polar ka mea hoʻoheheʻe maikaʻi loa no nā kānana organik.

Hoʻopili koʻikoʻi ʻia ka hana o nā kānana UV a pau e ke ʻano rheological o ka hoʻokumu ʻana a me kona hiki ke hana i kahi kiʻiʻoniʻoni like ʻole ma ka ʻili. ʻO ka hoʻohana ʻana i nā kiʻiʻoniʻoni kūpono a me nā mea hoʻohui rheological e kōkua pinepine i ka hoʻomaikaʻi ʻana i ka pono o nā kānana.
ʻO ka hui ʻana o nā kānana UV (synergies)

Nui nā hui o nā kānana UV e hōʻike ana i nā synergies. Loaʻa nā hopena synergistic maikaʻi loa ma ka hoʻohui ʻana i nā kānana e hoʻokō i kekahi i kekahi ma kekahi ʻano, no ka laʻana: -
• Hoʻohui i nā kānana hiki ke hoʻoheheʻe ʻia i ka ʻaila (a i ʻole ka ʻaila i hoʻopuehu ʻia) me nā kānana hiki ke hoʻoheheʻe ʻia i ka wai.
• 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 hoʻohua mai i nā pono ʻē aʻe, no ka laʻana, ua ʻike nui ʻia e kōkua ka octocrylene i ke kiʻi-hoʻopaʻa i kekahi mau kānana kiʻi-labile e like me butyl methoxydibenzoylmethane.

Eia naʻe, pono e noʻonoʻo kekahi i ka waiwai naʻauao ma kēia wahi. Nui nā patent e uhi ana i nā hui pū ʻana o nā kānana UV a ua ʻōlelo ʻia nā mea hoʻopuka e nānā mau i ka hui ʻana a lākou i manaʻo ai e hoʻohana ʻaʻole ia e hōʻino i nā patent ʻaoʻao ʻekolu.

E koho i ka kānana UV kūpono no kāu ʻano hoʻonaninani

E kōkua nā ʻanuʻu aʻe iā ʻoe e koho i ka kānana UV kūpono no kāu hoʻolālā hoʻonaninani:
1. E hoʻonohonoho i nā pahuhopu akaka 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 loaʻa iā ʻoe kahi chassis formulation kikoʻī āu e makemake ai e hoʻohana, e noʻonoʻo i nā kānana e kūpono me kēlā chassis. Eia nō naʻe, inā hiki, ʻoi aku ka maikaʻi o ke koho mua ʻana i nā kānana a hoʻolālā i ka hoʻolālā a puni lākou. He ʻoiaʻiʻo loa kēia me nā kānana organik inorganic a i ʻole particulate.
4. E hoʻohana i ka ʻōlelo aʻo mai nā mea hoʻolako a/a i ʻole nā ​​mea hana wānana e like me ka BASF Sunscreen Simulator e ʻike i nā hui e pono ai.e hoʻokō i ka SPF i manaʻo ʻiaa me nā pahuhopu UVA.

A laila hiki ke ho'āʻo ʻia kēia mau hui ʻana ma nā ʻano hoʻohālike. Pono nā ʻano hoʻokolohua in-vitro SPF a me UVA i kēia manawa e hōʻike i nā hui e hāʻawi i nā hopena maikaʻi loa ma ke ʻano o ka hana - hiki ke hōʻiliʻili ʻia nā ʻike hou aʻe e pili ana i ka noi, ka wehewehe ʻana a me nā palena o kēia mau hoʻāʻo me ka papahana e-training SpecialChem.UVA/SPF: E hoʻonui ana i kāu mau kaʻina hoʻāʻo

ʻO nā hopena hoʻāʻo, me nā hopena o nā hoʻokolohua ʻē aʻe a me nā loiloi (e laʻa. stability, preservative efficacy, skin feel), hiki i ka mea hoʻopuka ke koho i nā koho maikaʻi loa a alakaʻi pū i ka hoʻomohala hou ʻana o ka (s).
