Oil and cream separating
i made body cream with this proportion
shea 9%
oil 12.5%
glyceral stearate Peg 100 3%
Stearic acid 3%
cetyl alcohol 2%
dimethicone: 2%
water 57%
glycerin 10% phase c 1.5%
The texture is great. I’ve been experimenting this in fall/windet - no issues
Now that the temp is increasing am seeing 2 issues

Oil/cream separation

Mouldy (light green) at the top of the cream
What can I do to prevent this. How do I make this cream stable?

Do you high shear?
You didn’t write the name of preservative (I assume phase C 1.5% was for it).
You have a decent lipid input, increase you emulsifier and add rheology modifier - e.g. Xanthan gum

@garima this will not be stable without an alkali agent to saponify the stearic acid, not with that oil load anyhow. Stearic acid is your primary emulsifier there when used with an alkali such as triethanolamine, AMP or tromethamine, otherwise it is only a weak builder since cetyl alcohol is already in there. As for “mouldy”…what @Paprik said: find and add a good preservative and do it soon!

And add 0.2% EDTA too
