    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 friends
    I did a facial tonic. I used 1.65% microcare sb as a preservative
    However, after four months the product turns yellow. Then I reduced the amount of microcarbide to 1.1%, but I started to turn yellow again
    in formula
    4% Poloxamer 184
    1% propylene glycol
    0.2% allantoin
    0.5% Aloe Barbadensis Leaf Extract
    0.5% odor
    1.65% micro sister SB
    and had the same problem with facial cleansing gel and toothpaste. PH was less than 5.5 in all three formulas
    I 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
