No! First of all, if you find small quantities of pure amodimethicone in your country please give me the link. Amodimethicone is a cationic silicone (with great conditioning properties). Usually it is sold in a form of an emulsion which can’t be added to oil or silicone. So, if you find it, 20% medium weight dimethicone (like 350-500), 2% Amodimethicone, 0.5% of vegetable oil of your choice for claims, cyclomethicone qs. Can be used as consitioning leave in hair serum as well.

Big brand with one product?

[ngarayeva001]

You will not achieve a liquid product with BTMS-50. I can suggest how to make watersoluble, sprayable conditioning product but not oil as I am not aware of existance of oil-soluble quaterniums.
Amodimethicone is what I see in commercial products, however it’s impossible to find the pure version on the DIY market.

The best approach to the liquid beard oil would be 20% of Dimethicone, 79.5% of Cyclomethicone and 0.5% of any oil that you want to use as a claim ingredient.

[ngarayeva001]

BTMS-50 is 50% cetyl alcohol, of course it solidifies. You can’t fix this “error” because it’s not an error.

[ngarayeva001]

I can help you with the formula, but there are many aspects to it as Belassi mentioned. It should be commercialy feasible and it depends on your access to materials and your volumes. It also depends on the market: are people in your region willing to buy products with parabens/silicones/sulfates/whatever, or they want clean/organic/natural nonsense?

[ngarayeva001]

Adding 20% of hydrosol to the cool down phase will destabilise emulsion. Having said that, I recommend to get rid of both rose hydrosol and aloe vera at all - it’s bug food and will challenge the preservative system severely (even germall). They add a little less than nothing to the performace especially if it’s for personal use and you don’t need to add those as part of story. You already have fragrance and if you want it to smell like rose, consider adding synthetic rose oil (because natural is too expensive to be used in a hair product).
Move dimthicone to the oil phase. It’s not sensitive to heating and will help BTMS melting.
And the most important, add 0.5% of polyquat 7 or polyquat 10 for extra conditioning. It’s hard to overcondition curly hair.
Overall, it’s a decent formula but it’s always possible to improve things.

HLB of glyceryl stearate is 3.8 and you can make w/o emulsion with glyceryl stearate and IPM. I would say it’s much better to make w/o emulsions with esters because they are less greasy. W/O emulsions tend to be quite greasy by nature. HLB system isn’t that precise. It’s just a starting point. 

[ngarayeva001]

Fekher you can even use esters (high HLB) to make W/O. Type of emulsion depends on the emulsifier used, not oils. If you have glyceryl stearate and ,say, caprylic/capric triglycerides or IPM you can experiment with it to see that it works.

[ngarayeva001]

@Gunther, good point on CAPB. I would also say replace SLS to SLSa. Great foam and much more gentle.

[ngarayeva001]

@Mel55, I can see a couple of things that can be improved, but you should start a new topic to get help. It’s not in accordance with the rules of the forum to start discussing a new formula in someone’s thread.

[ngarayeva001]

1) You are using not particularly mild surfactants, and no cationic compounds that provide conditioning. 
2) There are many types of Dimethicone copolyol, and you didn’t specified which one you are using. 
3) What is glucose de?
4) Olive oil and cetearyl alcohol provides nothing for the formula. If you want olive oil as a claim ingredient you should reduce it to something like .2% so that it doesn’t interfere with the performance.
5) Coming back to silicones you added, keep in mind, the purpose of silicone is to reduce surface tention, this translates as “less bubbles”. This is not very desirable for consumers perception.

Having said all that, if you are not a hobbyist and want to make a product for sale, you need a professional formulation services for which you will have to pay. There is a section of this forum, where you can reach out to professionals and ask for services.

[ngarayeva001]

I don’t think there was a need in tagging me on the topic.

[ngarayeva001]

Depends on type of carbomer. Some carbomers forms get at a lower pH than others. Check with the manufacturer.

[ngarayeva001]

Sorry typo ‘film former’

[ngarayeva001]

Yes. You need a firm former for the hold. For example PVP.

[ngarayeva001]

Imagine taking picture of a cake and showing it to professional bakers with the same amount of information as you provided above. Do you think they would be able to tell you what’s in it?

[ngarayeva001]

Carbomer is a rheology modifier. There are many types, some are more clear than others. It doesn’t give a hold. 

[ngarayeva001]

@Belassi, I used himalayan pink salt in one of my experiments with salt curve and grains of sand in the bottom of the beaker were not that tiny. They were pretty noticeable  

I am giving a disclaimer before people start throwing rotten tomatos at me: it was one of my first experiements with thickening SLES, it wasn’t a final product, and that was the only salt I had in the kitchen. 

[ngarayeva001]

@TranVanHoach  what’s your benchmark? What properties that yellow thing supposed to have? This is not how you supposed to ask for help on a cosmetic chemistry forum.

[ngarayeva001]

Belassi, I am quite sure this one needs food grade of xanthan :smiley:
I literally opened this post because I saw the topic and that you are the last commentor and I expected such a comment

[ngarayeva001]

What is this and what is the question?

[ngarayeva001]

I don’t understand what is the problem with asking questions. Cosmetic formulation is a niche profession. There’s literally no information online. For someone with full time job for whom it’s a hobby it’s easier to ask a question instead of digging information in chemistry books. The absolute majority of them are outdated and not user friendly. Also when a hobbyist asks a question like ‘will tetrahexyldecyl ascorbate reduce viscosity of aristoflex?” Professionals of this forum start complaining that this question wastes their time and suggest ‘just go and try’. Sorry guys but one oz of the above mentioned active is $50 on lotioncrafter plus delivery plus customs fee. It’s easier to ask than wasting expensive material. I am not suggesting that experiments and research aren’t required but if you don’t like the question and believe that the person is lazy and doesn’t want to read don’t respond. This is what I do.

[ngarayeva001]

The majority of micellar water products in the market are made of either poloxamer 185 or PEG-6 caprylic/capric glycerides. Neither of those is efficient for dissolving water resistant products.

[ngarayeva001]

Here is another one:

INCI	%
Mineral oil	31%
C12-15 Alkil Benzoate	36%
Peg-20 Glyceryl Triisostearate	10%
PEG-40 HCO	10%
Polyethylene	10%
Butylene Glycol	1%
Glycerin	1%
Preservative	1%

More or less ok, but hard to wash it off. I am still working on it. I tried Peg-20 Glyceryl Triisostearate at 20% without PEG-40 HCO, but it doesn’t dissolve makeup as well as the version above.

[ngarayeva001]

There is no scientifically backed data that suggests that oil cleansers make acne issue worse.

Regarding the texture it’s not bar solid. You can make it bar solid if replace stearic acid and cetyl alcohol to polyethylene. And yes you can easily replace mineral oil to a lighter ester. I often blend mineral oil with IPM. 
I have 5 versions of this product but I find this particular formula is the best.
