kev siv
2-Hydroxyethylurea yog ib qho tshuaj pleev kom noo noo zoo heev uas muab cov khoom siv saib xyuas tawv nqaij ua kom noo noo zoo yam tsis muaj qhov nplaum thiab txo cov silicone hauv cov mis. Hydroxyethyl urea tuaj yeem nkag mus rau hauv stratum corneum, ua kom cov tawv nqaij noo noo ntxiv, txo qhov qhuav, sau cov kab zoo, ua kom tawv nqaij elasticity thiab muab kev xav zoo ntawm kev siv. Nrog rau feem ntau ntawm cov khoom siv tshuaj pleev ib ce sib xws, nrog ntau yam pH. Cov chaw siv: 1. Cov khoom siv saib xyuas tawv nqaij 2. Xab npum tes thiab cov khoom da dej 3.
Cov tshuaj ntxuav thiab xab npum4. Cov khoom siv rau menyuam yaus5. Cov khoom siv pleev thaiv hnub6. Cov khoom siv saib xyuas plaub hau. Cov tshuaj pom zoo kom siv: 0.5-5.0%.
Tus yam ntxwv tseem ceeb ntawm hydroxyethyl urea yog muab cov khoom siv saib xyuas tawv nqaij nrog kev ua haujlwm moisturizing yam tsis muaj kev xav nplaum, tib lub sijhawm, nws tuaj yeem ua rau tawv nqaij elasticity thiab rov ua kom tawv nqaij noo, thiab nws muaj kev sib raug zoo nrog ntau yam khoom siv saib xyuas tawv nqaij thaum sib xyaw nrog Chemicalbook, uas yog qhov tsis hnyav thiab tsis khaus. Hydroxyethyl urea kuj muaj qhov sib piv ua haujlwm siab. Piv nrog cov humectants kim, hydroxyethyl urea tuaj yeem ua tiav tib yam ntawm tus nqi qis dua.
Ntim thiab Xa Khoom

khaws cia thiab cia
Lus Cim: Khaws cia rau hauv qhov chaw txias, qhuav hauv cov thawv kaw zoo.
Kev siv tau: 2 xyoos
Khaws cia rau hauv cov thawv kaw. Rov kaw cov thawv kom nruj tom qab siv. Lub sijhawm khaws cia ntawm 2-hydroxyethylurea yog ob xyoos hauv cov thawv qub, tsis tau qhib.
Peev Xwm
60 MT ib hlis, tam sim no peb tab tom nthuav peb cov kab ntau lawm.
