You can use carbopol to increase the viscosity 1%-1.5% using TEA or NaOH/KOH to get ir to the right Ph. Lubrizol has a fórmula like the one you want to make.

first of all i want to gives you tanks for everything.
@vitalys how can i calculate the amount of tea that i need to use to neutralize the stearic acid or i can estimate it measuring the ph, whats the ratio and % of steric acid/tea or naoh that i need to ensure a stable emulsion
can you please tell me whats the emulsifier in the cold cream you mentioned
@belassi im going to try your formulation, which procedure can you sugest me to try the stability of a emulsion, im trying the 45ºC temp exposure and tried to centrifuge my creams but in 10ml batch i cant see the separation

@ozgirl thanks for ur interest and help, in my country we have currency exchange control, that means that i cant buy ingredients, the 98% or so of the lotions that i can find in the market are imported like nivea, ponds, avon, and others, but very expensive, there are a lot of handcraft creams that are available but doenst come with an ingredient list. i cant figure out how they are made, but judging by the prices and my research on my country marked they are ussing mineral oils or/and paraffin

@belassi thanks for your answer, i read that i can make my own glycerl steareate using stearic acid, usp glycerin and vinager, melting all and then filtering, have you heard something of that?, is that posible?, assuming is it possible what are the proportions?, i tried with sun flower oils but they feels too oily and the smells is awful

@Iaskedbetter Whats yhe function of TEA on the formula?, and which emulsifier do you recommend assuming tween80 as secondary, i also have nonylphenol eythoxylate on my avaible list
-
thanks iaskedbetter, im going to try your formula, so you are saying that i cant make a stable lotion with my current available ingredients?. i have the assumption that something is working on my current formula because the 90% of the lotion stay mixed for more than 3 months, only a little lf water goes to the bottom
I womder how a company in venezuela with my same avaible ingredients can make a lotion.
btw im ussing methyl and propyl paraben as preservative

Thanks ozgirl for your reply, the main problem with that blog is that he always use polowax, btms-50 or e-wax as emulsifing agent, and i cant use those because there arent available in my country, besides that i know a factory in my country that sells a cheap lotion that contains mainly paraffin oil and wax, but i cant make mines works.
