Professional Chemist / FormulatorNovember 3, 2018 at 10:58 am in reply to: pH slightly dropping@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.

Professional Chemist / FormulatorOctober 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. -

Professional Chemist / FormulatorOctober 30, 2018 at 12:09 pm in reply to: Formulation of Mild Shampoo supposed not irritant@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.
