azelaic acid is not very soluble in anything - your best bet is to make the product an O/W emulsion with a very polar oil (e.g. a salicylate ester) as the oil phase 

I can dissolve it with my propylene glycol

[Jaycetowww]

@Pharma i am trying to make it , and concerning the azelaic acid , I am going to dissolve it with the propylene glycol 

[Jaycetowww]

@Paprik @Perry

[Jaycetowww]

@chemicalmatt @Pharma
Changing the formular to this ; rose hydrosol ,distilled water , vegetable glycerine , propylene glycol 10 %, polysorbate  20, niacinamide ,salicylic acid 1%, azelaic 3%, liquid germall

would it work ? 

[Jaycetowww]

My azelaic was 2 % while my salicylic was 1 % 

[Jaycetowww]

Rose hydrosols 
jasmine hydrosols 
polysorbate 80 
Sodium lactate 
propylene glycol 
azelaic and salicylic acid

depends on Preservative use and in general its good to know if you have a ph shift during stability testing 
I used liquid Germall 

[Jaycetowww]

Here is the new development on my detox face mask  : 
I used my aqua at 50% 
xanthan gum 0.5% 
honey 1.7% 
glycerine 5% 
Activated charcoal 10% 
Clay 30% 
teatree oil 
silky wax 2% 
Preservative 

so I noticed it was thick but not thick like that, and the after washing it off the face , it felt like there was oil which am thinking is because of the honey . 

But apart from that , it was great . 

I did not check the ph tho or am I supposed to check ????

I want to throw in that it is quite Problematik to Mix Oils and Bentonite or Clay they absorb the oil very intensely and then will not have the Capability to do what they need to do on the skin. You use Clay in an Anti-acne mask because of the fact that the Sebum that is produced by the skin is food for the bacteria that cores the acne and you want to remove that oil from the skin so that the bacteria don’t have enough to eat to grow. although the clay absorbs the Bacteria from the skin if it is already full of oil it can not do that.  

You should be oil-free normally if you add oil to such a product it will only lead to more clay needed to absorb Sebum and Bacteria from the skin. Although The caracole will do the same as the clay so you put in 2 ingredients for the same effect. of course, if you want it to be black you can use 0,5 % of Carcole to get it black and let the rest be done by the clay it is more cost-efficient I would guess. 

Adding tee Trea oil you can do that in small concentrations to get the claims out of it or the Indication that people expect out of it. 

Although you need to be very careful with the Therm “Acne” acne is a medical condition and therefore you can not make a Cosmetic product with that claim it would be a medical product. 

I would suggest a Formulation like : 

Water: 50 %
xantan gum 0.4-0.9 %
Kaolin / Clay 10%
Glycerin 3-5 %
0.3% Tea Tree oil 
Cetyl alcohol 2-4%
Emulsifier for Rinsoff quality (Something that is very good as a self-emulsifing system) 
if you wanna use honey you can but it can lead to Product Issues over Different years of Collection due to changes in wax and Suger Content. 

Conservation. ( don’t use Potasiumsorbate you need too much of t and it will make some faces red after occlusive application for several minutes)

hope that helps.

Tobias 

Thank you
God bless you

Please try to make 50 or 100 grams of the product and review it. 
I have never worked with Bentonite clay so not sure how it behaves.

Although I think your product will be too runny (no thickener, unless bentonite will thicken it?), sticky (honey) and messy (charcoal). 

I will do that and give review 

[Jaycetowww]

That’s why I’m not adding water to it

The European Cosmetic Toiletry and Perfumery Association recommends that Tea Tree Oil should not be used in cosmetic products in a way that results in a concentration greater than 1% oil being applied to the body.

Interesting

Where can i find this data? 

I need to show it to some people

I’m not adding water , is that a problem @Paprik @Abdullah

Oils don’t mix with water. Your product will separate in one minute. 

You need to learn how to make emulsion so you can mix water and oil.

This is from the Opinion:

Tea Tree Oil is a skin sensitiser. Skin sensitisation may also be enhanced by irritancy. Neat
Tea Tree Oil and certain formulations at concentrations of 5% or more can induce skin and
eye irritation.
Based on clinical data, the current use levels of TTO are shown to induce contact allergy.

I would suggest you to make the product and try it. Frankly, I would not want to have that much Tea Tree oil close to my eyes and nose. 
Also, I would not want to clean the bathroom after rinsing 7% of charcoal    

Should I reduce the tea tree oil and charcoal , then add the remaining percentage to the rose hip oil

So I have to reduce the percentage of the tea tea oil 

[Jaycetowww]

I wwant to know if it will not irritate the skin , if the percentage is okay

What is your question/issue mate?

Hi @Jaycetowww 

I just want to point out that the formula that @MarkBroussard shared is patented by L’Oreal. I don’t think you’re planning on making a product to sell commercially but if that’s that case I would find a different formula to use. This particular patent only applies to US territories but I don’t know if they have filed patents in other countries too.

Summary of the patent:
“The present invention relates to single-phase solution compositions of L-ascorbic acid that provide enhanced…

Wowwww

@Jaycetowww

Here’s a simple formula that is a good starter for you:

Water (43.5%) + L-Ascorbic Acid (15%) + 1,3-Propanediol (45%) + Ferulic Acid (0.5%) + Phenoxyethanol (0.5%) + Sodium Hyaluronate (800-1200 kDa) (0.5%)

1.  Dissolve L-Ascorbic Acid in Water.
2.  Heat 1,3-Propanediol to 75C.  Add Ferulic Acid to hot Propanediol stirring to dissolve and make uniform
3.  Add Propanediol/Ferulic Acid mixture to Water/Ascorbic Acid mixture stirring to make uniform
4.  Add Phenoxyethanol to Step3 mixture stirring to make uniform
5.  Sprinkle Sodium Hyaluronate into Step4 mixture while stirring@300RPM. Continue stirring until uniform (approximately 2 hours)

As @Bill_Toge pointed out, you would probably be safe not adding a preservative to this concoction as its native pH will be somewhere in the range 2.5 to 3.0, but good practice for you starting out to develop the discipline of proper preservation.

Thank you mark , you are really a life saver

Are you using ‘pure’ Vitamin C (Ascorbic Acid)? One thing about this form of Vitamin C is that it is highly unstable on aqueous medium, so it is very alike that the formulation will change it’s color.

Also, 32% of Vitamin C is a VERY high concentration. I bet you don’t need that much in a formula. I also think that 4% is a VERY high concentration of Vitamin E. Speaking of Vitamin E, what form are you using, tocopherol or tocopheryl acetate?

And you won’t use any preservative? 

I was thinking since I added an anti oxidant , preservatives won’t be needed

[Jaycetowww]

@MarkBroussard thank you very much 

[Jaycetowww]

@Paprik thank you very much for this 🙏🏾

I just started my skincare formulation journey , that is why
