1, 3-Dihydroxyacetone
1, 3-I-Dihydroxyacetone obeye aziwe njengo i-glycerin, i-carbohydrate elula (i-triose) enefomula C 3H 6O 3. 1, 3-I-Dihydroxyacetoneiyi-ketose eyenzeka ngokwemvelo engaboli, edlekayo futhi engenabo ubuthi emzimbeni womuntu kanye nemvelo. Kuyisithasiselo esisebenza ngezindlela eziningi esingasetshenziswa ezimbonini zezimonyo, ezemithi nezokudla.
Amapharamitha Abalulekile Wezobuchwepheshe:
| Ukubukeka | Impushana emhlophe ukuya kokumhlophe |
| pH | 4.0~6.0 |
| Amanzi | ≤0.4% |
| Izinsalela ekushiseni | ≤0.4% |
| Isivivinyo | ≥98.0% |
| Izinsimbi ezisindayo(Pb) | ≤10ppm |
| Insimbi(Fe) | ≤10ppm |
| I-Arsenic(AS2O3) |
≤3ppm |
| Isitoreji | Gcina yomile futhi kude nokukhanya, isitoreji ku-2~8℃ |
Umsebenzi:
1. I-ejenti engcono kakhulu futhi edume kakhulu yokuzishukela ukuze uthole ukubukeka okungokwemvelo okunjenge-tan ngaphandle kokuchayeka elangeni.
2. Ukuvikelwa kwesithombe okubalulekile nokufakazelwe ku-UVA ngenxa yombala wesikhumba obangelwa I-DHA.
3. Ukufakwa ekwakhiweni kokunakekelwa kwesikhumba ukuze kusetshenziswe nsuku zonke ukuze kulungiswe noma kunwetshwe i-suntan.
Isicelo:
1. Isetshenziswa embonini yezimonyo, i-dihydroxyacetone isetshenziswa ngokuyinhloko njengendlela yezimonyo, ikakhulukazi njengoba i-sunscreen inomphumela okhethekile, ingavimbela ukuhwamuka ngokweqile komswakama wesikhumba, ibambe iqhaza ekuthuthukiseni umswakama, i-sunscreen kanye nokuvikelwa kwemisebe ye-UV;
2. I-Ketone ye I-DHA eqenjini elisebenzayo elinesikhumba se-keratin amino acids kanye namaqembu e-amino ku-Chemicalbook kufanele kube ukwakheka kwe-polymer ensundu, kwenza abantu bakwazi ukukhiqiza isikhumba esinsundu sokwenziwa, ngakho-ke nawe ungasetshenziselwa ukulingisa i-ejenti ye-tan, uthole imiphumela ibukeka futhi isikhathi eside. ukuchayeka elangeni insundu efanayo noma tan, kwenze kubukeke muhle.I-Dihydroxyacetone iwumkhiqizo ophakathi we-metabolism kashukela, edlala indima ebalulekile enqubweni ye-metabolism kashukela futhi inezakhiwo ezinempilo;
