    Is what is this %0.2 EDTA doing? 
    Should i increase it to reduce the iron availability?

    @PhilGeis im am referring to information in makingcosmetics website about phenoxyethanol and sodium benzoate incompatibilities. 

    can you tell me the book name or the info? 

    I already decided to replace HPMC with guar gum because of it’s incompatibility with phenoxyethanol in shampoo to stabilize pearlizer EGDS.

    List of ingredients with percentage of each

  • @Dreamer77 thanks for interesting information. 
    Does PQ10 and guar hydroxypropyltrimonium chloride also speed up the absorption of oil? 

    If yes at what percentage?

    Add 50g water to 50g NAOH and continue mixing it to reach more water to more NAOH quickly and see.

    @PhilGeis sure but if there is any known incompatibility it is better to know and change that i ingredient or preservation system.

    @Pharma @PhilGeis any comments on this.

    Lotioncrafter says: Benzoic acid is inactivated by non-ionic surfactant.

    Makingcosmetics says: Phenoxyethanol should not be used in formulas containing HE-cellulose or non-ionic surfactants. 

    One another website said phenoxyethanol is deactivated by highly ethoxylated surfactants. Does this include SLES or ALES?

    Thanks in advance

    I don’t know the reason but i know APGs at high amounts are not compatible with cellulose. Also decyl Glucoside is very hard to thicken but lauryl is very easy.

    Yes it is very stable. 
    Just use %0.3 xanthan gum or some carbomer in water phase. 
    And it is also liquid crystal.

    Use HPMC instead of HEC.
    Reduce decyl Glucoside to %1 or replace it with lauryl Glucoside. 
    %10 decyl Glucoside is very difficult to thicken

    The upper limit for DMDM hydantoin is %0.6, so why warning above %0.05?

     Finished products containing DMDMH must be labeled with the

    warning “contains formaldehyde” if the (free) formaldehyde
    concentration exceeds 0.05%

    @Bill_Toge EDTA is also anionic and not compatible with cationic surfactants. So how does that effect PQ10?

    April 27, 2021 at 12:09 pm in reply to: Suggestions on how to make this formula more moisturizing and less tacky

    @RedCoast i don’t think it was fume. The smell was lavender eo that i was adding. From just smelling the Product there was no problem but after applying it to face or hand i was felling something is not good and there was some tightness my chest. No irritation. Then When i was washing my hand or face after from the Product, the problem was solved. 
    I was adding EDTA at first and HCl at cool down. One day i decided to add it first at water face because it was powder not liquid,i first added EDTA then when i added HCl, a white powder like thing formed on top of water that was not soluble in water. Then i made another batch without EDTA and it was easily soluble in hot water. So i figured these two are not compatible.

    Then I made two batches separately one with EDTA and another preservative and one with HCl and both were amazing with no problem. 

    Then i checked it’s compatibility with each ingredient, it was not compatible with citric acid too.

    Mixing incompatible ingredients doesn’t mean the emulsion should always break. It means those ingredients will not do what you want them to do and may be some other side effects. 

    I was once mixing EDTA vs Ethyl Lauroyl Arginate HCl which are incompatible in emulsions. The emulsions were stable but i was felling some shortness of breath when i was applying the lotion to my body. When i found that these two are incompatible, removing each of it made a beautiful emulsion without any problem.

    For moisturization add %20 glycerin and %5 petrolatum. This works better than anything else you can compare to. The manage the aesthetics.
