Maintaining Viscosity At 50c

Posted by JackDerrington on September 1, 2020 at 7:14 pm

Hi all,

What ingredients can I try adding to a formula that must maintain a decent viscosity at 45-50c? (I am unsure of the exact requirements, but the product is leaking through what are pinhole sized holes in a pump packaging). I’m not sure why the product has holes in it, I think it’s somewhat standard.

Any ideas on a thickener that maintains viscosity at high heat?

Thanks!

Jack

To get a useful answer you need to give more information about the composition of your formula.

Hey Perry,

It’s a moisturizing cream with:

65-70% Waters
5% Cetearyl Alcohol / Polysorbate 60
3% Cetyl Alcohol
6-7% Butters (Shea, Cocoa, etc.)
12-13% oils including Menthol
0.5% Xanthan Gum

Hope this helps, thanks in advance! The requirements are for it to hold a higher viscosity under high heat due to the packaging.

More xanthan gum
Carbomer
Better packaging.

Thanks Perry,

Going to try two formulations with XG at 1% and 2%.

Does it usually hold up well up to 50c?

And yes, ditto on the packaging… However the client already has them so trying to figure out a way for it to work before telling them to get new packaging. Thanks!
