@Anca_Formulator Agree with @kivangel. You are using way too much of butters. Butters should compose no more than 10% of your formula, if you want a product that will be stable at different temperatures.
You can try thickening your formula with some…
@Graillotion I'll try a chelating agent
My preservative is a blend of Methylpropanediol, caprylyl glycol and phenyl propanol .
As for green tea, I use it as an antioxidant , but I can definetly try to take it out
Appreciate the advice
Thanks a lot @Pattsi, just one more question:
For TiO2 they say it can be used up to 25% in face powders in loose forms and as well not to be used in applications that may lead to lung's exposure by inhalation!!
Does this mean they exclude the loose…
Hi @Perry & everyone else.
I also came across these links.
I am a bit confused and seeking clarification please:
Does this study apply only to sunscreens where a combination of ZnO + other organic UV filters are present or even if ZnO is used a…
@Dennis I am using Arlacel 1689 (INCI Sorbitan Oleate (and) Polyglyceryl-3 Polyricinoleate) + GMS each at 5%.
@chemicalmatt Thanks for that. I am adding the water phase very slowly as you said. andthen homogenise. Do i still need to homogenise whe…

@chemicalmatt I used NaOHto neutralise stearic to pH around 7. Then homogenised. Then at the end I adjusted the final pH to 6.5 . Does this sound good or bad?
If you will put the samples under 40C as you said, how long incubation can predict a 3 ye…
Thanks @Abdullah I dohave cetearyl alcohol. I tried it but not happy with the feel.
Plus I would prefer to go cold process, since it is only for opacifying and i don't want to add any oils in this cleanser
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.
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 cooli…
@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 bec…
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.
