I-P-Phenylenediamine (PPD)

I-P-Phenylenediamine (PPD) iyi-amine enephunga elimnandi enephunga elimnandi eyaziwa kabanzi njengemaphakathi eyinhloko ephumelela kakhulu futhi evame ukusetshenziswa ekwakhiweni kodayi wezinwele oxidative (unomphela). Uma kuhlanganiswa nama-couplers kanye ne-hydrogen peroxide, i-PPD ikhiqiza imiphumela eqinile, ehlala isikhathi eside yombala kuwo wonke umthunzi ogcwele kusuka ku-blonde kuya kokumnyama. Ibuye isetshenziselwe ukudaya uboya, izindwangu (ikakhulukazi ama-para-aramid fibers), amakhemikhali enjoloba, kanye nanjenge-ejenti ekhulayo yezithombe.

Imibuzo Evame Ukubuzwa (FAQs)

Q: Ingabe i-P-Phenylenediamine (PPD) iphephile ukusetshenziswa kumadayi ezinwele?

A: Uma isetshenziswa ngokuvumelana neziqondiso zokulawula (≤ 2% kungxube yokugcina ye-oxidative) futhi isetshenziswa ochwepheshe abaqeqeshiwe abanokuhlolwa kwe-patch okufanele, i-PPD ibhekwa njengephephile i-EU SCCS, i-FDA, ne-CIR. Ihlala iyindawo emaphakathi yezinga legolide ukuze kuzuzwe umbala wezinwele unomphela onamandla, ongabuni.

Q: Kungani i-PPD ibangela ukungezwani komzimba kwabanye abantu?

A: I-PPD iyisizwisi esinamandla sesikhumba (i-Skin Sens. 1). Cishe i-1-6% yabantu ingase ibe nokungezwani komzimba nomuntu ngemva kokuchayeka kaningi. Ukuhlolwa kweziqephu zamahora angu-48 kuyimpoqo emazweni amaningi ngaphambi kokusetshenziswa kokuqala.

Q: Ingabe zikhona ezinye izindlela zokudayi izinwele ezihlala unomphela ezingena-PPD?

A: Yebo, ezinye izindlela ezifana ne-toluene-2,5-diamine sulfate (PTDS) noma i-hydroxyethyl-p-phenylenediamine sulfate (HEPP) zisetshenziswa ekwakhiweni 'i-PPD-free', nakuba zinganikeza ukusebenza komthunzi okuhluke kancane nokuphila isikhathi eside.

Umbuzo: Ingabe i-PPD ingasetshenziswa kumadayi ahlala unomphela noma wesikhashana?

IMP: Cha. I-PPD idinga i-oxidation nge-hydrogen peroxide ukuze ithuthukise umbala futhi isebenza kuphela kumadayi e-oxidative unomphela (wezingxenye ezimbili).

Q: Uyini umehluko phakathi kwe-PPD ne-Para-Aminophenol (PAP)?

IMPENDULO: Zombili zingama-intermediate ayinhloko, kodwa i-PPD ikhiqiza amathoni apholile, ashier kanye nabamnyama abajulile, kuyilapho i-PAP ngokuvamile isetshenziselwa imithunzi ebomvu efudumele neyethusi.
