Hi there,

Most of the reputable suppliers in Europe do say, more or less, something like this regarding the GS SE “The pH value of the emulsion is optimally between 6.8 and 8.2 and thus already in the slightly alkaline range. You can still achieve stable emulsions with a ph-value of 5.5 if you combine it with other emulsifiers. GSC palm oil free is suitable here.

But also gel formers, like Xanthan transparent or Xanthan Cospaderm X34 with an input concentration of 0.2-0.4% or fatty alcohols, which stabilise the water phase, allow to lower the ph-value to ph 5.5 with a little lactic acid.“

Thank you @MarkBroussard , and @Graillotion (for the comment on CCT that opened my eyes in this regard)- I’m still formulating for myself and family/friends, but it’s good to know beforehand such important details.

Hi there,

Not planning to launch anything yet but if “a local manufacturer will handle the formulation and production” I would expect them to do just that.

There are quite a few online sources which can give you an idea of what is selling best on the market, and what are the ingredients used in those products. Here’s one link, randomly chosen: https://www.glamour.com/gallery/best-dark-spot-corrector

Hi there,

I’m assuming it’s the same serum you described in your other post. So you used/want to use xanthan gum+glycerin in an oil? Do you want to replicate a certain product? I’m asking because it’s not clear why would someone add water soluble peptides and xanthan gum and glycerin in an oil mixture.

Hi, no intention to confuse you. I said a minimum pH of 4.5 and I didn’t state the maximum (8). So no worries about pH🙂 Best of luck with your new experiment.

Hi, given your formula and assuming that your pH is minimum 4.5 (Hallstar guidance), it looks like the issue could be the process. I can only say that heating at 75C, adding the hyaluronic acid in the cool down, and following the advice given in the thread regarding the mixing process, should give you the right result. Also, the emulsion might not look too thick right after making it (so don’t try to achieve thickness by overmixing), but it will reach it’s final consistency in aprox. 48 hours.

Hi there, this is a topic with quite some history here. If you just type in “search forums” any word related (stick deodorant/sodium stearate/deodorant) you’ll find a wealth of info which will definitely help you. Happy researching🙂

Hi Everyone I have a problem with a formulation about Hair water based pomade and I would like you to help me solve it The problem is that…

Hi, you say you want to know “the mixing time and speed to prepare, for example, a cream”. I don’t own the mixing equipment you have, but: you would increase your chances to an answer if you would reffer to a specific formulation of the said cream and the quantity you’d want to make. Different emulsifiers require different times and speeds as do different quantities. Other ingredients present in your product can influence the answer too. Regarding the rpm of your equipment, the answer should be out there, in the World Wide Web😉

Hello, “fresh” member here😀 I’ve seen up-close two very different cases: a friend’s daughter whose straight hair went “Shirley Temple” when she was about 12-13y, and another friend, whose almost “afro” hair went straight in the process of giving birth (the doctors blamed the stress factor). So yeah, Mother Nature is something…

It is not wrong, it is a nonsensical action: you need water as a solvent for water soluble ingredients.

You could sign-up for the beginner course offered here, to get some knowledge on ingredients and emulsion making.

Check the ingredients on the eyelash serums with peptides on the market: water is the first ingredient on the list.
