Please Help - Severe Cloudiness In Polymer Phase of Styling Gel Prototype
Hi All:
Having a serious “cloudiness” issue in the polymer phase ( of a normal hold styling gel prototype I’ve been working on.
My carbomer phase (A - 72% water, 0.5% carbomer, 0.2% Disodium EDTA, 0.02% Benzopbenone-4 and 0.1% DMDM Hydantoin preservative) is completely clean and clear.
There’s no debate that an inferior chemist is involved here (me), but I’m wondering if perhaps an inferior styling polymer product could be causing the excessive cloudiness?
I’m Basically using a 5% polymer solution with 3% / 2% of PVP / DMAPA & PVP K 90 respectively.
After 30 minutes of continuous mixing of (20% water and both styling polymers) in phase B, the solution looks like a semi-frothy milkshake.
I’m then separately mixing 4:1 polysorbate-20 with a fragrance until crystal clear.
Next I’m adding to Phase B 0.5% TEA, a drop of FD&Caramel color along with a hint of clear flaxseed / soybean oil. Finally, I add the clear polysorbate / fragrance solution to phase B and mix for another 5 minutes.
When I combine phases A and B together and mix (for another 30 minutes), the perfectly clear carbomer solution turns into a milky, creamy gel (thanks to problematic phase losing all of its clarity.
When I run my finger thru the mixture I can literally feel some GRIT, which is a red flag, and I’m suspecting it’s either the PVP K90 or the PVP / DMAPA. Both are from “Making Cosmetics” (“PVP” and “Acrylates Copolymer” products).
I’m hoping the solution to the problem is obvious to the more seasoned chemists in the group, but right now I’m very confused, as there is literally a full hour of mixing taking place on this prototype, and still not obtaining anywhere close to the clear finished gel as I would hope.
Any help you can provide would be so appreciated! Thank you so much!
