Nrov science on tshuaj pleev ib ce

Cov khoom xyaw tseem ceeb ntawm cov tshuaj pleev ib ce muaj xws li cov khoom siv tshuaj tsw qab, xws li cov roj ntsha, uas yog cov tawv nqaij roj av thiab tiv thaiv cov tawv nqaij hauv cov tshuaj pleev ib ce.
Txhawm rau tiv thaiv oxidation ntawm roj, waxes thiab hydrocarbons hauv cov tshuaj pleev ib ce, antioxidant xws li tocopherol thiab tert-butyl hydroxyfennel feem ntau ntxiv {}}
Cov tshuaj tiv thaiv xws li cov dav hlau yog siv los tiv thaiv kev loj hlob ntawm cov kab mob thiab pwm thiab tswj hwm qhov khoom ruaj khov thiab kev nyab xeeb ntawm cov khoom .
Tsis tas li ntawd, moisturizers xws li glycerin, propylene glycol thiab sorbitol yog siv los ua kom cov tawv nqaij hydrated .
Cov khoom xyaw kom zoo nkauj thiab lawv cov haujlwm:
Cov kuab tshuaj: xws li dej, cawv (ethanol, isopropanol), feem ntau yog siv rau cov khoom tsim nyog thiab muab cov khoom tsim nyog thiab muab cov ntaub ntawv tsim nyog thiab cov khoom siv tau.
Roj: xws li txiv roj roj, cov roj txiv maj phaub, thiab lwm yam}}}}} pa .
Antioxidants: xws li tocopherol, tertiary butyl hydroxyfennel, thiab lwm yam khoom xyaw thiab tswj cov khoom zoo .
Cov tshuaj tiv thaiv: xws li cov parabens, kom tiv thaiv kev loj hlob ntawm cov kab mob thiab pwm thiab xyuas kom cov khoom muaj kev nyab xeeb {}}
Cov tshuaj tsw qab thiab cov pigments: xws li flavors thiab pigments, txhawm rau txhim kho qhov tsis hnov ​​tsw thiab pom ntawm cov khoom .
