    I have idea thatadding EDTA improves Foaming, however 0.65 seems high to ordinary. I know some formulation reach 0.2%.

    Thanks a lot Perry, I thought that vasline is soo stable versus oxidation.

    So in bad condition of storage can just two months make vasline have oxidation ?

    Then can vitamine or can you propose uv filter to solve the problem?

    For sure the ratio of sabowax AE is a secret however depending on your oil phase you can make your own successful emulsifiers combination that’s really easier and most important.

    Make élimination test : with making basic sample (sample without any white powders that you have) then divide your sample to samples “the number of white powders you have” . Then add to each sample just one type of powder and watch which powder causes that.

    Thanks alot, so the list ingredients is:

    Water, mpg, sabowax AE, ceteareth 20,gms,parafin oil, petrolatum, Cetearyl alcohol, edta, citric acid, sensicare c1090, perfume (which cause loosing viscosity) . I eliminated hot process because cream already cold now that’s why I did not go with wax, Cetearyl alcohol…

    Thanks for the information about adding fragrance with low shear around the 40°C I didn’t know about it is the any explanation and better process for adding fragrance (lower temperature, other shear …).

    I will do researchement about your in put, just because I should correct quickly I made just try one with ultrez 21 and other with carbopol 996. Ultrez 21 gave better result but for economical reason I made correction with carbomer 996.

    When I find occasion I will try some others corrections with :Hec, Hpmc, parafin wax, Cetearyl alcohol…

    How did you calculate 16% please and with @PhilGeis do you think for pH between 5_5.5 combination 0.8%phenoxyethanol 0.2 sodium will be good for cream and no high ethoxylated cosmetic products?

    March 20, 2024 at 11:14 am in reply to: Advise for increasing viscosity of cream

    My ph 4.9 however have you reference for 0.5% level because from researchement I find in cosmetic it is used in 0.2% level.

    Thanks for this interesting add I suspect to synergy that’s why mentioned that 0.2% did not give convinced thickening effect(in water not in emulsion) . May I will try it when I have time.

    March 16, 2024 at 8:59 am in reply to: Advise for increasing viscosity of cream

    For the grade of xanthan gum that I have in only water(not emulsion) 0.2% did not give convinced viscosity and even in sensory aspect it is not lovely.

    March 16, 2024 at 8:56 am in reply to: Advise for increasing viscosity of cream

    The level of perfume is near to 0.8% I know that’s soo high but I must work sush level, then sush level is not the reason because with other fragrances with same level I reached very better viscosity. The level of sensicare c 1090 is 0.8% when you make researchement this preservative is effective for bacteria, fungicide and yeast, so why you supposed to add some fungicide?

    March 11, 2024 at 12:07 pm in reply to: Hair Matte pomade preservatives

    For water based hair wax can sensicare 1090(phenoxyethanol +ethyl glycerin) do the job for good preservation? I then a combination of 0.8%phenoxyethanol +0.2 benzoate de sodium is it efficient for the same products.

    If not increasing the level of phenoxyethanol +benzoate de sodium can lead to good preservation or did you recommend any adequate preservative for based hair pomade containing 30%of ceteareth 20?

    I suggest to make 1 kg sample then if you don’t find the problem I will go for that the cause is changing process from small sample to industrial one.

    Changing process ( temperature, pressure,type of stiring, speed of stiring, order of adding ingredients…)
