It’s a common beliefs that oils are better for hair, but our hair (above the skin surface) are actually dead. So all you do to them is a ‘cosmetic’ effect. And silicones are much better for a visual effect of ‘healthy hair’. I was working on a hair conditioner formula recently, and my first approach was to add 10% of argain oil in it (because oil is good for hair?). I was advised to reduce it to 0.5%. The product is much better now! I understand if oil is cheaper and thus more feasible for you, however as Perry mentioned, it’s going to be heavy. And I will add as per my experience with sucragel, it’s also sticky.

I have just checked sucragel’s technical specifications (I only used it to make an oily gel with vegetable oils), it says that it can
gel almost any non polar ingredient such as vegetable oils,
esters, and silicones. So, it is definitely worth trying to make a small batch and see how it works. @Fekher let us know if it works. It sounds as an interesting idea. -
I used sucragel to make a face wash (74% almond oil, 25% sucragel, 1% preservative fragrance and vit E). What I noticed the product is a bit sticky. It’s ok for an emulsifying face wash, but I am not sure that you would want that effect on your hair.

I am using exactly the same looking one with similar technical characteristics. It’s ok for small batches.
-
Wow! It’s just beyond nonsense. I wish novocaine worked this way. Would be great for painful aesthetic procedures such as hair removal ?

@Microformulation I am learning:)

No, pH isn’t the only factor you should use amphoteric surfactants to make product tear free. Obviously ingredients such as essential oils have to be either excluded at all or uses at a very low %
-
Anhydrous LAA systems are not very pleasant to apply. You either make an aquaneus gel of LAA and HA plus your extracts (that won’t do much) that will be pleasant to apply and oxidize very soon or you make a minimalistic gritty mixture of propanediol and LAA and skip all other ingredients. And it will be so heavy that you won’t need any glycerin. I think that propanediol might be replaced with propylene glycol. Sorry but you cannot have it all when you have such a limited access to ingredients.
-
I will say it again, you will not get an anhydrous system with glycerin. It is a humuctant not a solvent. You either need to find a solvent or just accept that the formula can’t be stabilized because you don’t have access to derivatives.

I am not questioning xantham gum’s efficacy as a thickener, however I personally avoid it at any cost. It contributes to, what I call, ranch sauce texture. I am sure that professionals know how to combine it properly but I feel like xantham kills texture of carbomer and make the product slimy (even at 0.2%). I can tell that a commercial product was thickened by xantham without even seeing LOI. There are so many great rheology modifiers to explore! @Dtdang, there are many carbomers. I guess this table will be useful.
I used 940. As you can see, one of the worst performances. There’s also Ultrez 30 that isn’t in this table. I have just received it. Will be testing it today and share my thoughts later. -
This is very strange. I mixed those two surfactants in many products and never experienced stickiness. I don’t know could it be quality of your materials? That’ my last guess..
-
You must be joking? It’s in russian.
-
I agree with Belassi. Polysorbates can be sticky. Also I suspect that the fragrance is a bit high.
-
Thank you @Microformulation. Found it.
-
Thank you @Perry. My bad, I shouldn’t have generalised this way. I just keep seeing many not very advanced questions, that’s why I said “majority are not chemists”, which is most probably not the case. I admire your patience sometimes, as I noticed that you answer questions even more basic than the emulsion stability. I totally agree that people should do their research first. I have been reading this forum (blog and podcast) for many months before I decided to join as a member and started asking questions. That is why I highly encourage hobbyists to subscribe for blogs that explain chemistry in a simple language, analyse LOIs of commercial products and experiment. Sometimes people don’t know where to start and unfortunately do not have access to many basic cosmetic ingredients.

@BeardlyGentlemen, read about INCI names. Microcristalline wax is Cera Microcrystalina.
Microcrystalline wax is a hydrocarbon wax derived from petroleum
Petrolatum is a North American term for petroleum jelly (INCI name Petrolatum) -
Jojoba oil is just a carrier oil. It doesn’t have any magic properties and definitely doesn’t help with “bacterial infection and stuff”.
-
Speaking about dilettants, @Microformulation, may I ask you to through some article, on how to design the process the way to to create the smallest possible micelles, at me :smiley: My first real overhead stirrer (yay!) is coming on Friday.
-
@Microformulation, I had no intention to say that the right
scientific approach is useless. But its different levels of knowledge we are
dealing with here. Many people here are making lotions the same way they would
bake a muffin. When I just started I bought literally the first
“ewax” available on amazon, mixed it with cold water, dumped
some oil in that concoction and was utterly amazed when it didn’t emulsify. Now
I am reading more or less serious papers, doing my research on the active
ingredients and make more advanced mistakes, like mixing amphoteric surfactant
with anionic and bringing pH below 6 (I am a dilettante and I know it).
People learn through trial and error, and yes hard core science is the best,
but you can’t teach differential equations to someone who doesn’t know arithmetic
yet. It would just demotivate them. Disclaimer, I personally appreciate your
comments and learned a lot thanks to you. -
Even calculated HLB isn’t a guarantee of the success, however it’s important to know certain rules.
I understand that professionals are getting very frustrated when someone asks for an easy solution, which clearly doesn’t exist. However since the majority of the members of this forum are not chemists, it’s important not to discourage people from learning.
@Dtdang, overall you are right, but there is no such thing as anti-bacterial oil. You need an emulsifier compatible with the oil (if the emulsifier is nonionic calculate the HLB), you want to make sure the oil is stable (not going to get rancid), you want to add your antioxidant, broad spectrum preservative and chelating agent and yes, airtight container makes everything better. -
I am a hobbyist and absolutely fine with “not natural” ingredients. In fact I prefer them in the most cases due to their better performance. I prefer parabens, but I can’t buy them where I live, and have to order from the US, which is more expensive (custom fees are real here). So I would rather keep my precious tiny bottle of parabens for something more serious than a rinse off product.
-
This is very strange actually because I used CAPB and decyl glucoside together and have not noticed any sticky feel. Have you tried excluding other ingredients? Could it be fragrance?
-
Thank you @bigziom! I wasn’t sure if Phenoxyethanol + Ethylhexylglycerin would work. I would prefer to use it, because surprisingly enough it’s cheaper for me than parabens (because I have to order parabens from the US).
-
You are using conventional thickeners and emulsifiers. You will not get a clear product with cetyl alcohol.

Post your formula.
