There are different grades of xanthan gum.
Normal xanthan gum won’t suspend. Try a refined non-sticky version at 1% . Check keltrol CG-SFT or Cosphaderm X-Sof

Thanks @Fekher & @ketchito for your suggestions
I am using ultrez 20 not 10, so it should be good in regards to electrolytes.
I also have it in incubator for almost 2 months now at 45C and no separation. Just the problem of viscosity. 
What emulsifier would you suggest @ketchito

[Shams]

Pre-grind your pigments using a coffee grinder. And then disperse them in your oil phase and complete the rest as usual. You will need to homogenise your formula as well using a stick mixer while the product is in a paste-like consitency while cooling down(not too hot, not room temperature) to ensure it is grinded well and completely dispersed in the formula. This is how I usually do it on lab scale and it comes out perfect . And this is not with pre-treated pigments

I am sorry , I meant O/W emulsion

Thanks Pharma,Totally agree, HLB never comes out correctly in reality. I just use it as a start. Will definetly look into HLD more

@MarkBroussard Sorry i wrote this before i saw the other post where you made it so clear to me. Thanks again

Great Thanks @MarkBroussard. That clarifies it all.

@MarkBroussard Much appreciated Mark. 
I literally have nothing else but some emollients, emulsifiers and extracts.
So i don’t need NDA. Do i still need to list it though and register my establishment.

@ozgirl for this. I have gone through it and what i understood is according to this my product can be considered as GRASE, but my consultant-haven’t agreed with them though- says no, i still have to apply for new drug application. Not sure is it because they want to complicate it to get the job or because this is the truth.i have a moisturizer with SPF, I use only zinc oxide at 21%, i am not using any colorants nor any prohibited substances that FDA list. 
Do you have any idea about this case. Thaks

@MarkBroussard
Thanks for your reply.
Actually we do have a full range of products. This moisturizer is just one of them and i’m asking because i’m confused is it cosmetic or OTC.
Do you have any clue how does “GRASE” formulas work. 

[Shams]

Thanks @Perry
IS there any link or document that i can follow to check on what acceptable and what not acceptable as claims for cosmetics

[Shams]

Thanks @Perry . Do you think it is possible to do it by myself (R&D chemist) or does it require a consultant better

I tried both HEC and xanthan gum for a 70%w/w alcohol content and both didn’t work.
Xanthan gum can hold up to 60% alcohol , but not more
