Q&A: What’s zinc PCA and how do I formulate with it? (#alltheingredients)

In the July Q&A, Charlette asked, I’ve been looking into developing some skincare for acne/break out prone skin. I’ve been reading about Zinc PCA-but cannot find it ANYWHERE among our usual wonderful suppliers. I ended up requesting samples on Knowde. From what I read-it is not the same as Zinc Oxide? Do you have any suggestions…...

Let’s pick up where we left off yesterday in creating this light, non-greasy summer weight lotion using Varisoft EQ 65. We figured out what we wanted to include in our water phase, so let’s take a look at the oil phase.

I hate summer so very much, but I’m handling it far better this year because we just had central air conditioning installed, and it can get so chilly, I need to put on a light cardigan. (I’m the type who wears shorts all year ’round, so this is a big big deal!) But I know…...

It offers a silky, smooth, powdery skin feel without being too waxy or draggy, the…...

We found we had a lower-than-expected pH with our burst of citrus clarifying shampoo yesterday, and I attribute that to the pH of the two hydrosols I used. Yep, these are just a few of ingredients that might affect the pH of your products! I have so many hydrosols in my workshop, but I thought…...
