Preservative for bug food ‘Colloidal Oatmeal’…
I try and stay away from ‘bug food’ in my products, but recently tried colloidal oatmeal, and for a guy whom is rarely impressed with hyped ingredients, this one caught my eye, and tantalized my fingertips.
It really left my skin silky, even 8 hours after application. Not claiming it did anything, just stating that for me, there was a textural enhancement on my skin.
So here are some of the parameters.
Due to B3 inclusion, I like to keep creams about 6.0 pH, which really throws a wrench into the preservative selection. NOTE: If all the good options require a lower pH, I can (for double the price) switch to a reduced nicotinic acid form of B3. So if the best option requires lower pH, I am open to hearing your recommendations…just state the pH requirement.
The other parameters are: I prefer (for customer perception) to formulate without Parabens and formaldehyde-releasing preservatives.
Currently I use Euxyl® PE 9010 and Phenethyl alcohol, and it would therefore be economical to reuse these products, and possibly add something to them.
SIDEBAR: I found that Colloidal oatmeal also upset the emulsifiers I was using. Can anyone tell me why this would happen? (I will make a more robust emulsifying package in the product that will contain the Colloidal Oatmeal.) That package was Mont 202/GSC/Aristoflex AVC.
Next package will contain some 165
