potassium sorbate change color
Merhaba sevgili arkadaşlar
Yüz toniği yaptım. Koruyucu olarak 1.65% microcare sb kullandım
Ancak dört ay sonra ürün sararır. Sonra mikrokarbür miktarını% 1.1’e düşürdüm, fakat tekrar sararmaya başladım
formülde
% 4 Poloxamer 184
% 1 propilen glikol
% 0.2 allantoin
% 0.5 Aloe Barbadensis Yaprağı Ekstresi
% 0,5 koku
1.65% mikrokardeş sb
ve yüz temizleme jeli ve diş macunu ile aynı sorunu vardı. PH, her üç formülde de 5.5’ten azdı
Potasyum sorbat tandan kaynaklanıyor sanırım ama neden?
Sadece sodyum benzoat kullansaydım sorun olur mu?

Hello dear friendsI did a facial tonic. I used 1.65% microcare sb as a preservativeHowever, after four months the product turns yellow. Then I reduced the amount of microcarbide to 1.1%, but I started to turn yellow againin formula4% Poloxamer 1841% propylene glycol0.2% allantoin0.5% Aloe Barbadensis Leaf Extract0.5% odor1.65% micro sister SBand had the same problem with facial cleansing gel and toothpaste. PH was less than 5.5 in all three formulasI guess potassium sorbate stems from tan, but why?Would it be a problem if I only used sodium benzoate? -

My Turkish comrade, does not that preservative include benzyl alcohol? Benzyl alcohol causes the discoloration, not the acid. Parabens will work fine here, BTW.

Sevgili dostlarım, bu koruyucu benzil alkol içermiyor.

My dear friends, this preservative does not contain benzyl alcohol -
Sorry to hijack the thread, but do you think a preservative with Benzyl alcohol may do the similar discoloration of dyes in hair gel as well @chemicalmatt
