Ethylhexyl triazone hmoov

 

Ethylhexyl triazone hmoovyog UVA Sunscreen Tus Neeg Sawv Cev, uas yog cov tshuaj lom neeg tus neeg sawv cev Sunscreen. Nws raug tso cai siv nyob rau hauv Sunscreens hauv European Union, Australia, thiab Nyij Pooj, thiab cov koob tshuaj yuav tsum tsis pub tshaj 5%. Txawm li cas los xij, Asmeskas FDA tseem tsis tau pom zoo nws siv.

 

Kev nqus tau zoo wavelength ntawm ethylhotexyl triazone yog nruab nrab ntawm 290-320 nm. Thaum siv ua ke nrog Uvinul ib qho ntxiv, SPF tus nqi yuav tau nce ntxiv.

 

Nws yog cov roj-solubble godorber nrog UV-B nqus tau muaj peev xwm. Nws muaj lub teeb muaj zog ruaj khov, muaj zog dej tsis kam, thiab kev ua tau zoo rau cov tawv nqaij keratin.

 

1. Lub cev tsis ua

(1) tsos: pob tshab rau lub teeb daj viscous kua (xim tsawg dua los yog sib npaug rau 30 apha)

• Tsis-Polar System: Toluene (1: 1.5), Xylene (1: 2)
• Ntws: 1. {02-1. 05 g / cm³ (25 degree)

 

2. Tshuaj Ntsuam Xyuas Kev Ruaj Ntseg

(1) Thermal stability: decomposition temperature >280 Qib (TGA Ntsuam Xyuas)
(2) PH zam: ruaj khov ntawm pH 3-11 (nrawm nrawm xeem)
(3) Kev ntsuas nyiaj hydrolysis: 24-} teev tus nqi hydrolysis<0.5% (60°C water bath)

3. Nto Kho Tshuab

(1) Cov khoom siv hlau hlau

• Txhuas anodning da stabilizer (inhibiting dendrite loj hlob)
• Electropilating addions: nce qhov ntom ntom ntawm txheej (txo qhov porosity rau<5/cm²)

 

(2) Kev loj hlob ntawm cov txheej tshwj xeeb

• Nkoj antifouling txheej: biological adhesion tus nqi txo los ntawm 72% (ISO 11306 xeem)
• Chev Txheej Txheej Txheem: nto roughness ra tus nqi tsawg dua lossis sib npaug rau {{0μm

 

 

1. Cov khoom siv hluav taws xob
