Shampoo Formula Development
Hello everyone,
I am currently developing a pearlescent shampoo formula.
1. The formula contains Polyquaternium 10 and Guar Hydroxypropyltrimonium Chloride. Can I soak them together in water so that they swell together? If so, what temperature should I put the mixture in after swelling?
2. My formula also contains Cetyl alcohol and stearyl alcohol. However, after monitoring the stability in the incubator for a few days, the sample has small white particles. Are these particles fatty alcohols?
3. What temperature should the pearlescent ingredient be added to?
If you have encountered a similar situation, please help me.

You can add both polymers to the main batch at the start with high mixing speed (don’t add them to the water without mixing). No heating required.
About the paticles, are they on top or at the bottom of your product?

They are evenly distributed in the sample, however after about a week they float to the top, while the bottom part is clear.

Just out of curiosity, are the particles jelly-like and spherical, or irregular, brittle and very white?
-
white opaque particles, uniform in size

Then it’s your fatty alcohol. There are a couple ways to add them: either to make heat the whole batch untill you melt them, of mixing them with some water and surfactante as a premix. Which way you’re doing it?

I heat the wax in a separate cup, mix water and surfactant in a separate cup, when the two cups reach about 70-80 degrees Celsius, I add the wax to the water phase containing surfactant and stir until it dissolves evenly and uniformly.
