Quick question. Why would you add a preservative to a anhydrous system? Are you trying to ensure mold prevention should the blush come into contact with water? Or are there other water soluble ingredients to be included? Just trying to learn. Thanks!

Thanks for the suggestion, but unfortunately anything with “sulfate” in the name will run our customers off. Even though we try to educate on the differences it’s still a non-starter from the beginning with our customer base. I think what may have happened is I subbed Shea Butter for the Shea Nut Oil and got the adverse reaction. I’m going to do comparisons between the two options and see if I get my original results before I need to change the surfactants. Thanks!

I think I figured it out! I could possibly add a peg to the formula such as Peg-6 or peg-120 (both of which I have on hand). Or I can add a polysorbate 80 as a secondary surfactant. All of which have higher hlb. I guess I’ll have to test out these additions. Please let me know if anyone thinks I’m going down the wrong path.

@Belassi what surfactant addition would you suggest? The cationic guar and the Glycol Stearate IP aren’t sufficient considering the low amount of oils? I did check to see what the hlb for the liquid shea butter would be and it’s an 8. The glycol stearate has an hlb capacity of 6. But once again I figured since I had such a low oil phase that I didn’t have to completely worriy about the hlb especially since I was mixing it with the cationic guar. Is it possible that I could just add more glycol stearate or do you think I should go add another secondary emulsifier to bring the hlb capacity up to 8 or more? I appreciate your’s and anyone else’s response. You can probably tell I’m somewhat attached to this formula. It has great results and sensory.
