my addition of  Sodium betabisulfite ?

Preservative: Phenoxyethyanol & Potassium sorbate.

What do you think?

[amitvedakar]

Can I  choose Ascorbic acid 15% +ferulic 1% + HA 0.3%+ Niacianmide 2%

OR MAP +ferulic+HA+Niacinamide.

As i read HA + Niacinamide good combination while Niacinamide can affect integrity of the Vitamin C.

[amitvedakar]

Thank you @MarkBroussard  for clearing my doubts.

Hydroquinone is prescribed pharma ingredient here in my country.

[amitvedakar]

I Think
any Skin lighting ingredient only work, if people have deficiency of that ingredient.
Is that true?

[amitvedakar]

@MarkBroussard

What do you think about adding L-glutahione in above suggested formula?

[amitvedakar]

Thank you @MarkBroussard. for Your guidance  on HA.

 

Feel great  receiving All Guidance & help.

[amitvedakar]

I think color solubility matters. Try different Oil soluble color.

I heard about 3-O-Ethyl Ascorbic Acid and tried a couple of commercial products made with it. I however noticed they were anhydrous. Is it water soluble? Not all forms of vitamin c are water soluble.

  It is water soluble.  My supplier can also supply MAP-ASCOBAT-C.

He suggested 3-5% MAP. Is MAP effective alternative?

My 20% LAA solution has 2 pH.  How to get pH 4.

Preservative SMP & SPP.

Does BHT & BHA work here?

[amitvedakar]

We use both at once in clenser

[amitvedakar]

What about 3-O-Ethyl Ascorbic Acid?

above ingredient suggested by supplier.

and adding Hyaluronic Acid instead of vitamin E.

well  the cost of alpha tocopherol & Dl alpha tocopherol  is 4 fold.

Hyaluronic Acid is not cheap too. but available in gm. and required percentage is less.

there are three types available. would go for middle (Medium molecular weight).

What are suggestions/ Guidances?

[amitvedakar]

tocophrol acetate  is soluble in PEG 40 Hydrogenated castor oil. (1:5)

but adding Water make the solution hazy. 

[amitvedakar]

What about following Materials?

Triclosan, Chlorhexidine Gluconate Soln. or Cetrimide

I don’t know above are useful or not?

[amitvedakar]

@MarkBroussard

Thank you very much for your guidance.

At present I have limited material.

Formula makeover required.

So arranging material and  restart.

Meanwhile  I try for  water qty to  solublize LAA & remaining  PG.   

I have also Tween80 & PEG 40 Hydrogenated castor oil. Try to solublize vitamin E acetate.

Thank you all for taking interest & valuable guidance.

@UsmanAli

check out ingredients of EMAMI 7 IN 1 OIL .

[amitvedakar]

@ngarayeva001  thank you.

Link info Lot to learn.

Preservative Should be Sod. Methyl Paraben+ SPP.

I avoided first because I want to try primary mixing.    

 

[amitvedakar]

for base oil try Sesame oil or coconut oil.

Amit paraffin oil is the base for most of the oils in such cases and there is nothing wrong with it. I am not sure how you are basing  your observation, I have used this oil for last 20 years and had no issue at all no matter what the critics/pseudoscientific crowd had to comment. 

I think if your product is Herbal than Paraffin oil should be avoided. (region matter in india paraafin oil is banned in herbal hair oil). If your product is cosmetic than you can continue with white oil. Other country may not have problems with white oil.

[amitvedakar]

Thank you all.

I omit Wheat germ & dimethicone.

PG for moisturizing & I thought only water base not good for application & feel.

Vitamin E liquid is DL alha tocopherol acetate.

can i use vitamin as powder.

Vitamin E acetate powder comes in 50%. (solubility checking).

I also dissolve LAA  17% in IPA 20 to 30% & other PG to make 100. solution found no color fade for two month. but can apply on face.

I found sodium gluconate in some serum formula as stabilizer. but they use derivative of vitamin c. does it work in Ascorbic acid formula.

Emulsifier suggested by @MarkBroussard  & @Dtdang are new for me.

I have lot to work on this.

Thank You all once again for taking interest in my problem.

[amitvedakar]

If you want your product gives good result, then you should avoid white oil.

It is used to make product cheap.

[amitvedakar]

What is white oil?

[amitvedakar]

Well thank you all for taking interest & Suggestions.

I’d suggest to amitvedakar to read about the Hoppler viscometer and how to simulate it.   

At present we don’t have, try for that.

Well by adding Nacl i found some difference in thickness.

@Gunther

It’s CAPB SB- Cocoamodopropyl betaine having active 30%

@ngarayeva001  

I increase CAPB  7-8% & try.

Salt should be added by dissolving or sprinkle directly & mix.

what is advisable?   

Thank you All.

[amitvedakar]

My Shampoo pH  6.

I tried Nacl and result is OK.

In shampoo i am going to cut down percentage of my herbal Extract to 1%.

I think that is problematic.

well when I make nozzle side down shampoo runing out of the nozzle.

Nacl made some difference.

 Can Nacl be added upto 1%? 

[amitvedakar]

@Chemist77  Thank you very much

[amitvedakar]

@Chemist77  FW- Facewash.

It means i have to mix all other materials  (preservatives, GHTC, Herbal Ext. etc  )in SLES first & then should add CDEA,   Betaine, POly Q 7.

[amitvedakar]

Well,

can adding CDEA separately in surfactant make any difference in thickness?

We add all surfactant all to gather & mix. 

[amitvedakar]

Perry said:

With SLES, Betaine, and CDEA you don’t need a thickener. Just adjust the viscosity with salt.  Do a salt curve analysis.

yes sir,

Thank You.

One more question: Does salt make skin or hair Dry?
