PS. no point would be adding 2 surfactants, such as BTMS with Cetrimonium Chloride or your mentioned Steartrimonium Chloride.
@Paprik can I use bhms 50 in making skin moisturizer lotion? As you said it is surfactant.
It is a surfactant, however cationic one. Therefore it is not really suitable for hydrating products.
For standard emulsions you should use anionic and non-ionic ingredients (leave cationic ones for hair care). -
MySkinRecipes - hell yeah! I ordered once, currently preparing another order. Once you order and pay, they send you all datasheets, COA, SDS’s etc … very good. They have decent amount of info on each ingredient.
And shipment was not crazy at all .. from Thailand to NZ was $50 and it took a week only!! For example from NewDirection (Australia) it is about $70!! And Trulux (also AUS) similar cost. So for me it is not brainer
And the option that you can order custom amount is just amazing.
I was super happy with them so far.
Happy browsing their website. I could not get enough and was spending waaaay too much time inspecting all ingredients they have
-
Hmm, just realised … as it is a lube and most likely will be used on specific areas, check all ingredients are suitable for that use.

Lavender hydrosol = expensive. You would need to use quite high input to get some decent aroma. But if budget allows, why not.
Aroma oil = you mean fragrance oil or essential oil?
Fragrance oil = cheaper, don’t need to use an antioxidant, if solubilised properly you should not worry about separation.
Essential oil = need of antioxidant, again, if solubilised correctly, you should not worry about separation. -
Haha, love the answers. I would actually answer the same way : Nope.
Seriously nothing compares to them. -
As mentioned, Niacinamide is very stable.
However, personally I would add that after emulsification. Where the temperature would drop to at least <70°C. Is it water soluble, so it would go into your formula very easily. -

1. I have in my mind that pure Tocopherol is corrosive to the skin, but I cannot find anything to support that on the internet now.
But 5% seems a lot. Cocoa butter is quite “resistant” to rancidity. Try to lower it (add that as a last step before pouring it off).
I believe the Beeswax is also high, not sure how your product looks like, but it must be pretty hard?2. With the extract it depends what base do they have. I believe they are not glycerin based as they would need to list the glycerin.
The Hyaluronic acid could be dispersed only in the product and can be there at 0.001% .. so can the extract tho.
The main thing there is castor oil and Shea butter in my opinion.

There is always a chance for instability and separation
You can, of course, add that into your emulsion, just follow correct processes (temperature, antioxidant if required, etc.. ) And test it out.
Happy formulating

I would check old discussions mate. There’s been some good ones about Urea.
-
I am not sure if I understand properly.
Are you looking for an emulsifier? Essentially you cannot mix hydrophilic and hydrophobic ingredients without something that will hold them together.Polysorbate 80 could help, but only to, more or less, solubilise some of the lipid into water.
PS. What hydrophilic antioxidant do you have?
-
This was my first one long time ago … sorry, not sorry, but trash
Good maybe for water, but definitely not for products. If you are serious about formulating, please get something better.
At this time I have this one - PH220. And you buy only electrodes after. If you take care of them they will last you a long time. Cost was $130NZD - for the meter and it already came with PE11 electrode. -
Hello,
I’m sorry to hear that. You would need to supply your whole formula, so we can take a look and see what could possibly went wrong.
(Stabiliser, chelating agent, preservative etc … ) -
Sure,
https://ec.europa.eu/growth/tools-databases/cosing/index.cfm?fuseaction=search.simple
search for an ingredient. Find the ingredient, open it and you can see Cosmetics Regulation provisions (Annexis) and SCCS Opinions. They are usually loooong articles, so if you have problems with sleeping you can read them all, oooor just jump to the end to the conclusion and find your answers.
Hope this helps?

Hello and welcome.
You would need to share your whole formula mate. Otherwise we won’t be able to help you.

Lamesoft PO 65 (it can cause instability to the product), … ethoxylated lipids (PEG-30 glyceryl cocoate), etc …
Do a google search, plenty will come up -
A note - if I understand it correctly you are solubilising preservatives?
I would say this is not great, use more “water-loving” one, do not solubilise it. It needs to be available for the whole products, not being “trapped in the micelles”. -
Both ingredients are doing basically the same so I would stick to one and test it out. Check regulatory limits (usually they have a special one for leave-on products) and go with it. Below are limits from CosIng (Europe).

You can add a small amount of glycerin to prevent from “drying of the product.”
If you add small amount it should not effect the foam. If you add propylene glycol it will lower the viscosity of your product.If you’re talking about about “drying the skin”, use some superfatting agent or similar.
-
Yeah, good point @PhilGeis. I should have mention to be careful to keep the preservative in its functional pH.
-
If I understand your question correctly you are asking how to increase final pH in your product? (After adding Geogard ECT the pH dropped?)
If so, yes, you can use NaOH (30% solution for example) or other alkaline pH buffer.
-
I wish there was that simple answer. Every oil is different and needs a bit different amount of solubiliser. I would start at ration 1:1 and try it out .. into pure water. If it gets cloudy, increase the ration 2:1 (solubiliser : oil). You can go up to 10:1 sometimes.
PS. You can also stick to Polysorbate 20 in my opinion
PSS. What is the purpose of the oil in your formula?
Happy formulating
-
You can use something like Guar Hydroxypropyl Trimoniumchloride or a Polyquaternium (-7 for example).
This will help condition your hair and won’t cause stability issues in presence of anionic surfactant. -
You can use any surfactant (preferably anionic, with amphoteric and non-ionic) to create a liquid handsoap. The choice is yours. And it will be even milder as the pH will be more skin friendly.
You can you SCI, however it is a bit tricky to work with. It is better in “bar” formulas.
Hope this helps?

Euxyl PE9010 is stable up to 120°C. Which you won’t achieve if you’re making an emulsion (or any other standard product). So it is safe to use it in water phase and heat it up.
In my opinion, it is almost recommended to incorporate this kind of preservative as soon as possible to get the best action.
