There are plenty of options from bamboo powder to pumice

Remove castor oil completely, replace polysorbate 20 with polysorbate 80 and up it to 10%. Castor oil is used in lip care a lot. One of the reasons is that it has quite a unique fatty acids composition and leaves a barrier (I don't want to use a wor…

I don’t think you can compare it with polymethylsilsesquioxane, those are very different.
-
@Graillotion, this one is nice https://lotioncrafter.com/collections/silicones-alternatives/products/lotioncrafter-el40 lotioncfater should have set of samples for elastomers. You might want to consider trying to select the one you like. I have no…
-
Even if it separates sometimes it’s a stability issue that needs to be addressed. Polarity should be considered when mixing oils. They all are very different.
-
Agree with the previous comment. You need silicone elastomers not just dimethicone. I would also have a look at ronaflair range https://www.merckgroup.com/en/brands/pm/ronaflair.html
-
Polyxydroxystearic acid is for dispersing pigments. It has some thickening properties but not much. It will also make your oil blend cloudy. Btw, I had my eye on polyamide-3 for a while. Have you tried it? I wonder if it allows creating a transpare…
-
Cannot guarantee as I have not tested that myself but usually C12-15 Alkyl Benzoate helps with mixing silicones and high polarity oils, so maybe adding some to your blend helps it to mix properly. Speaking of polyamide-3, I tried polyamide-8 and it …
-
It doesn’t perform well with high polarity oils (the one I have is covasilic 15). I tried it in both octyldodecanol and CCT and it didn’t thicken them at all. I have not tried it in squalane, but it thickens hydrogenated polyisobutene. Since those t…

@Andraous I don’t get your point. If bacteria can’t grow in your formula (assuming it’s self preserving) why would you need a preservative?
-
I don't think you will notice any effect even above 0.5%, to be honest.

I read that story about Tresemme class action and thought I need to buy some DMDM until it is completely banned..

Glyceryl Stearate SE can be used as a primary emulsifier although I prefer Glyceryl Stearate and PEG-100 Stearate. It’s one of the most versatile and robust o/w emulsifiers. Try a combination of polawax and GMS SE. You would need to keep pH above 7 …
-
I think it’s all different questions and you need to post them separately. Re: hyaluronic acid serum, what is in that formula? HA forms clear gel, it’s something else that contributes to cloudiness
-
You take this https://www.ulprospector.com/en/eu/PersonalCare/Detail/2667/216584/XIAMETER-PMX-1501-Fluid and dilute it with more cyclopentasiloxane. Done. If you want to get super fancy, add fragrance (mixed in alkyl benzoate) and 3-4% of phenyl tri…
-
Such a good question. I would also add a question on how much they think they are going to sell. Some would want to start with something like 500 jars of a moisturizer which translates into 25kg. I am not sure it’s possible to find a manufacturer wh…
-
I don’t see this approach in commercial products very often. You would make your life easier if you ditch cationics. But if it’s important for you to keep it this way, you need to increase cetyl alcohol for ‘butter’ consistency. Speaking based on my…
-
And how are you going to emulsify dimethicone and oil?
-
Carbomer is anionic. You can use cationic guar or even some grades of polyquaternium 10 but it will not be a traditional conditioner
-
It won’t be a traditional conditioner. Most of cationic emulsifiers must be melted. You can use cetrimonium chloride but you still need something like cetearyl alcohol to thicken it. The only way around it that comes to my mind is to get creative, m…

Happy New Year all!

If formaldehyde releasers isn’t a problem then use germall plus powder. I find it works well in formulations where transparency is important. I can’t comment on whether it will preserve your particular formula and you need to do all necessary tests …
-
You need chelating agent anyway as part of your preservative system speaking of which, I understand you rely on diols here. I am no expert by any means, but it doesn’t look sufficient to me especially with aloe added (aloe introduces additional pres…

To illustrate how the approach changes based on type of product: https://incidecoder.com/products/aveeno-daily-moisturising-after-shower-mist https://incidecoder.com/products/aveeno-moisturising-lotion https://incidecoder.com/products/aveeno-sens…

Back to Dr. Geis’s advice, have a look at Aveeno. It’s a well known brand under Johnson&Johnson. It has a variety of products and their entire marketing story is based on oatmeal. I had a quick flick through and as always there’s no one size fit…
-
I have not tested it myself but it looks like Sepinov EMT 10 should be able to do this if you are looking for a gel texture not a stick https://pixibeauty.co.uk/products/inshower-steam-facial?variant=13256005746755

@Belassi, after I read the story about your dogs, I only wash my cat with a mixture of SLES/CAPB and water (10% ASM) that I mix and use right away (so no preservative). Provided it’s just three ingredient and aesthetics of shampoo is the last thing…
-
@Belassi, what are you using for your dogs now? I wonder if parabens are safe for animals? Something like germaben II for example?
-
They make great shampoos too. Argan oil is their most known I believe. This is what I used to buy before I started dabbling in surfactants. All of them are made of Sodium C14-16 Olefin Sulfonate and CAPB. Some include SCI (looking at position at LOI…

@PhilGeis Dr. Geis, it always fascinated me how some bacteria manage to multiply in steam distilled water.
