I’ve done accelerated stability test (at 60 celcius), and my cream experienced a phase change after 3 weeks…

@Perry44 halo thank you for the respon.

I used basic ingredints:

- span 80 4,5%

- tween 80 0,5%

- glyceryl stearate 4%

- Cithrol GMS 40 1%

- cetyl alcohol 2%

and citric acid for adjuster.

If w/o emulsifier and o/w emulsifier are used together, viscocity will increase and make the cream is getting harden, isn’t it? and it will make cream easy to wash (not water resistant). I’ve tried to add salt in water phase but still separate, anyone can please help? Anyway thank you for your answer

[Rufiano]

Yes, i am adding the water phase to oil phase slowly (drops by drops using pipet) and i used mgs04 as electrolyte stabilizer in water phase

[Rufiano]

It’s about my R&D SOP in my company & i always use that temperature for acccelerated test, for other product too

But geepee, can you tell me whats wrong on my formula? am i using too much w/o emulgator?

Previous, i once used mgso4 for stabilizer at water phase but the result was same, stable on 3 weeks only.

[Rufiano]

My formula is about 75% water phase & 25% oil phase.

And i add the water phase to oil phase ad 70 C…

I used Emplilan EGMS with the INCI is Glycol cetearath.

Here’s:

Cetyl OH 2%

Gms 4%

Glycol cete 1%

Span 80 2%

Plurol 3%

Do i use too much emulgator??

[Rufiano]

Sorry i didnt get it, what do you mean excessive? the temperature, isn’t it?

[Rufiano]

Here’s the formula:

Aquadest

Glycerin

Chlorpenesin

Cetyl Alc

Glyceryl monostearate

Glycol cetearath

Span 80

Plurol oleique

IPM

Mineral Oil

ZnO

Can you help me what is wrong with my formula?
