Inorganic Sunscreens Daim Ntawv Thov
Inorganic Sunscreens yog tsim nyog rau kev siv tiv thaiv UV tsuas yog cov tshuaj tiv thaiv meej meej lossis tshuaj tsuag aerosol. They are particularly well suited for baby sun care, sensitive skin products, products making “natural” claims, and decorative cosmetics.
Inorganic UV lim cov hom

Titanium Dioxide
• Feem ntau UVB lim, tab sis qee qib kuj muab cov kev tiv thaiv UVA zoo
• Ntau qib kawm sib txawv qhov ntau thiab tsawg, txheej thiab lwm yam.
• Feem ntau cov qhab nia poob rau hauv kev kub ntawm nanoparticles
• Cov me me tshaj plaws yog qhov yooj yim heev rau ntawm daim tawv nqaij tab sis muab kev tiv thaiv UVA tsawg; Qhov ntau thiab tsawg muab cov kev tiv thaiv UVA ntau tab sis muaj ntau ntxuav hniav dawb ntawm daim tawv nqaij

Zinc Oxide
• Lub taub lim dej UVA feem ntau; qis SPF nws zoo dua TiO2, tab sis muab kev tiv thaiv zoo dua li Tio2 hauv nthwv dej ntev "UVA-I" cheeb tsam
• Ntau qib kawm sib txawv qhov ntau thiab tsawg, txheej thiab lwm yam.
• Feem ntau cov qhab nia poob rau hauv kev kub ntawm nanoparticles

Qhov kev cuam tshuam ntau yam ua tau haujlwm ntawm UV lim

Kev ua yeeb yam ntawm Titanium Dioxide thiab Zinc Oxide sib txawv raws li cov khoom ntiag tug ntawm cov qib tshwj xeeb siv, piv txwv li. txheej, daim ntawv lub cev (hmoov, roj-roj dispersion, dej-raws li dispersion).Cov neeg siv yuav tsum sab laj nrog cov neeg muab khoom ua ntej xaiv cov qib tsim nyog tshaj plaws kom tau raws li lawv cov hom phiaj ua tau zoo hauv lawv cov qauv ua haujlwm.

Cov kev ua tau zoo ntawm txhua tus neeg lim dej tau cuam tshuam los ntawm kev coj ua tus cwj pwm ntawm cov qauv thiab nws muaj peev xwm ua daim tawv nqaij txawm, kev ua yeeb yaj kiab. Kev siv cov yeeb yaj kiab tsim nyog ua yeeb yaj kiab thiab cov tshuaj ntxiv rheological feem ntau pab txhim kho txoj kev ua tau zoo ntawm cov ntxaij lim dej.
Nthuav kev sib txuam ntawm UV lim (symergies)

Muaj ntau cov kev sib txuas ua ke ntawm UV lim uas qhia cov symero. Qhov zoo tshaj plaws synergistic cuam tshuam yog feem ntau tau tiav los ntawm kev sib txuas cov ntxaij lim dej uas ua kom zoo sib xws hauv qee txoj kev, piv txwv li: -

• Ua sib txuas ua ke UVA cov ntxaij lim dej nrog UVB lim
• Ua ke sib txuas ua ke nrog cov lim dej erraulic

Tseem muaj qee cov kev sib txuas ua ke uas tuaj yeem muaj lwm cov txiaj ntsig, piv txwv tias nws tau ua kom muaj kuab tshuaj duab yees duab xws li Butyl MethoxyDibenzroyslmethanots.

Txawm li cas los xij ib qho yuav tsum nco ntsoov ua kom muaj lub siab ntawm cov cuab yeej fwm hauv thaj chaw no. Muaj ntau ntau cov patents kev sib txuas ua ke ntawm UV lim thiab cov kws lim dej yog qhia kom txhua zaus yuav tsum txheeb xyuas lawv tsis siv ib qho patents thib peb patents.

Cov kauj ruam hauv qab no yuav pab koj xaiv UV lim UV yog rau koj daim ntawv kom hniav zoo:
1. Teem tawm cov hom phiaj ntshiab rau kev ua tau zoo, kev ua kom zoo nkauj thiab npaj siab rau cov qauv.
2. Xyuas cov ntxaij lim dej twg tso cai rau kev ua lag luam.
3. Yog tias koj muaj cov qauv tsim tshwj xeeb uas koj xav siv, xav txog cov ntxaij lim dej twg yuav haum nrog cov chassis ntawd. Txawm li cas los xij yog tias ua tau nws yog qhov zoo tshaj plaws los xaiv cov ntxaij lim dej xub ntiag thiab tsim cov qauv ib puag ncig lawv. Qhov no yog qhov tseeb tshwj xeeb nrog inorganic lossis qhov uas tsis muaj cov tshuaj organic.
4. Siv cov lus qhia los ntawm cov khoom siv thiab / lossis cov cuab yeej ua ntej xws li Basef Sunscreen Simulator kom paub cov kev sib txuas ua ke uas yuav tsumUa tiav cov phiaj xwm spfthiab UVA lub hom phiaj.

These combinations can then be tried in formulations. Hauv-Venro SPF thiab UVA cov qauv kev sim siab yog muaj txiaj ntsig zoo tshaj plaws muab cov kev sib xyaw ua ke, cov ntaub ntawv ntau ntxiv tuaj yeem sau nrog Kev Kawm Tshwj Xeeb:UVA / SPF: Ua kom ua tiav koj cov kev cai xeem

Cov kev sim ua tau, nrog rau cov txiaj ntsig ntawm lwm qhov kev kuaj thiab ntsuas kom xaiv tau qhov kev xaiv zoo tshaj plaws, kev txhim kho kev txhim kho ntawm cov qauv kev tsim qauv.
