Can you explain it more that what is your final formulation, what is the pH of your final product.

[vjay]

If you can write inci so everybody will understand and give a reply.

For example i dont’ know the ASI, Maki bead 2, Daitopersian ZN-70-300 xp.

and if you can add average % so that people will guide you.

[vjay]

you can make a reverse process like first add texapon into the main vessel and add slowly water in it with continuous mixing may be it will work for you.

What is in the manufacturing differenece in Dimethicone 20cst and 350 cst

What is the chemically difference.

[vjay]

Dear All thanks for your suggestion i will definitely try lactic acid.

[vjay]

base on which parameter we can select for our formulation.

At present i want to develop body wash sulfat free so on what basis i can chose any one from these two.

Application and stabiltiy wise which is better.

[vjay]

ok

Thanks dear

I want to know that if Sulfat ash - 2% in report so can we understand that in the material 2 % sulfate is there ?

[vjay]

I have done so many trial and route cause analysis and based on that I came to know that perfume is a culprit.

Thanks to all of you guys to give the ideas.

[vjay]

ok

Can I will try with iron oxide and anybody can help which colour stabilizer I have to use.

Can anybody told me that what could be the reason

[vjay]

Which thickener I have to use in this kind of formulation.

Or I have to use Xanthan Gum.

[vjay]

Sorry Guys,

I want to Make (O/W emulsion - 30 % oil and 70 % water).

Maria please share your view with me.

[vjay]

Hi becksbarrow,

I want to make W/O emulsion and pigment % are (Titanium Dioxide 5 to 7 %),(Iron oxide Yellow 0.5 to 1.0), (Iron oxide Red 0.1 to 0.5) and (Iron oxide Red 0.05 to 0.1).

can you suggest which emulsifier I have to use for BB Cream.at present I am trying steareth 2 & steareth 21 emulsifier from croda.

Can you suggest which emollient has a best dispersabiltiy for the pigment. At present I am using Caprylic Capric Trigyceride as an emollient and dispersabiltiy.

for 100g and 200g rnd batch how we can pre-milling your pigments (that’s why I tried pre dispered and coated pigments also)

I am adding dimethicone 5 % also in my formulation

 

 

[vjay]

Thanks Bobzchemist

[vjay]

ok.

If any scientific reason are there ?

 

[vjay]

No its not for better miniaturization but for buffering the pH purpose & alone Lactic Acid lotion pH may be less than 3 & you can’t formulate.

[vjay]

thanks to all of you.

I will remember it.

[vjay]

You can do the challenge test (Preservative efficacy test) then do the 45°C stability study at least for 6 months and if passes the microbs (TVC & TFC both are < 10) then you can put into the market as per my knowledge. and m

Without octocrylene ?

They are not facing any photo stability issues ?

[vjay]

I am using both in our mass market product I am using PEG 150 distearate & In premium product I am using Arlypon TT because its costly compare to PEG 150 distearate.
