Microcrystalline cellulose is not suitable for hot process

I don’t understand your process. GMS and Stearic Acid and Cetyl Alcohol are all solids at room temperature. How are you possibly getting them into an emulsion at room temperature?

Honestly, I think you need to start over from scratch. On top of all the other problems with your formula, there’s not a good suspending agent in there for the TiO2.

@Bobzchemist
1. I am not getting them at room temperature.I am heating them at temperature upto 75 to 80. because KAD is dissolve at temperature of 80 degree.

2. yes, i think there is problem in my formula. As i said yesterday, that the emulsion is prepared but today i see a small flakes are see on the surface of cream. I remove Tio2 and microcrystalline cellulose. I think it is due to recrstallization of KAD? What should i do to avoid this.

My new formula is
A
Water-71.2
EDTA-0.3
B
LLP-3
IPM-5
Dimethicone-2
Hydrogenated polyisobutane-2
Cetyl Alcohol-2.5
Stearic acid-4
GMS-4
KAD-4
C
Polyacrylamide & C13-14 Isoparaffin & Laureth7 - 2

- - and even after all of this discussion I don’t see an effective emulsifier present.

@johnb
Sorry again! I am adding Acrylamide / Sodium Acrylate Copolymer, Mineral Oil (Paraffinum Liquidum), Trideceth-6 as a emulsifier.

I don’t think that is a good enough emulsifier for the formula stated.

I agree with Bobzchemist that the whole thing needs a careful re-evaluation.

The literature for Cosmedia ATC (which corresponds to the mixture you quoted) states that:

The prime function is as a rheological control additive for applications within the toiletries and cosmetics industries.

It is NOT claimed to be an emulsifier.

@johnb
Thnx! I am also agree with you and Bobzchemist. I have to change formula.
What should i do to avoid recrystallization of Kojic acid Dipalmitate?

Perhaps when you have an acceptable, stable formulation worked out the solubility problem will disappear.

Have you seen this?
