    hi @shireen make your Lol in percentage to have more suggestions and for stearic acid i see it used not at high level so check ph of your product if it is good then no need to neutralisation unless you can use NaOh to do it.

    @erickafalves actually my interpretarion matching the decreasing of ph and changing fragrance note that your perfumes in product are not stable enough so as probable solution i suggest to add more preservative or change it  that’s may solve your problem.

    @UsmanAli actually ph between 10 and 11 is real problem for skin and it is normal to cause irritation ph should be generally in cosmetic below 8.

    Update : i make hair creme-gel based on olive oil and carbomer so it gives   medium holding and smoothing effect  without flaking ☺.

    @shaujaat actually formaldehyde is very toxic ingredient wich you should change to another preservative , even the level of use is too high must be 0,1 % as maximum reaching 0,05 %|.

    @Marysurnita even liquid can be mesured by kg you just use a balance to know the adequat weight or use the relation: mass = volumic mass * volume.

    October 30, 2018 at 3:47 pm in reply to: My transparent soap is not solidify

    @Romis A lot of corrections are needed as i see : Actually stearic acid make soap creamy and decrease the transperency of soap so for the transperency you need high soluble oil as coconut oil , you need also to reduce greasy % and to modify % of solvent respecting the following % in pic.
     for having solid soap you should use between 40% and 60% saturated oil better 50 % however  you have just  (18/48 saturated oil ) so i suppose to decrease the % of SLES and increase the % of saturated oil to have harder bar.
     About changing TEA to ethanol that prouves that you need to learn more about soap so TEA can be solvent right but it play also as Alkalin ” Neutralizer of oils” so if you change it by ethanol you must add an adequat amount of NaOh.
     wish that all is clear unless you are welcome for more explain.

    @Chemist77 the % of polyquaternium is not random and i have  not access to polyquaternium 87(Luviquat sensation )  and i will not use dimethiconol so as you see for all this reasons polyquaternium 10 in 0,5 % will be the best choice.

    For APG i have idea that they are mild surfactants but what about foam and cost compairing to dissoduim cocoamphildiacetate?

    In my country suggar is too cheap but may it will not give effect in shampoo.

    And for ph if i can not obtain final ph equal to 5 i will delete Salicylic Acid.

    @ngarayeva001 actually i’am not talking about solvent i meant it when i said solublizer , solublizer is ingredient used to dissove other ingredient which is not soluble or has bad solubility in solvent i wish that difference between solublizer and solvent is clear  also solvent has important % in Lol however solubilizer has lower % .  “Almost problem of transperency return to bad solubility wich means our solvent is not good enough to dissove desired ingredient where the need of solubilizers”.

    @AmitKaria not as much easy as you think almost ingredients can have solublizers i gave you a start for probable solution of  your problem if you want  you can make research and may you solve it unless you are free.
    @ngarayeva001  something like that Peg 40 , polysorbates are solublizers for oils in aquatic solution so here is not the same we must know what are the type of aloe vera’s compositions ” i guess Aminic acids and sels”  and what are the adequat solubilzers of aloe vera’s compositions in water … wish that is clear.

    @ngarayeva001  @AmitKaria Actually what i see it is not problem of electrolyte resistance of ultrez because as it is clear that the obtained gel is viscous , the problem of transperency according to me can be solved by Aloe vera’s solubilizer that what i see and may we should make research about it ” as first impression i think aboul ethanol but to be more correct must know the Aloe vera ingredients and what can be theire adequat solublizers.
