Planning for the Saponification Values of Rosemary Oleoresin 2% and 5%

Rosemary Oleoresin 2%

Rosemary Oleoresin 2%

I love to learn. It is my passion. It is what gets me so excited to get up in the morning and start my day. And you, dear readers, contribute so much to everything I am exposed to. You also encourage me to continue to the question the “familiar”. I have some exciting news to share with you. Are you ready? Drum roll please.

Rosemary Oleoresin 2% and Rosemary Oleoresin 5% both have saponification values. Now what does this mean for you if you add it to soap? Well, this is dependent on how much Rosemary Oleoresin you are adding to your soap. Anything that is added 2% or more will greatly affect the superfat of your soap. This means unless you account for the saponifation value of the Rosemary Oleoresin, you are actually superfatting at a higher rate than what you may realize. It doesn’t mean it is bad, it is just something for you to be aware of.

If you make soap with either Rosemary Oleoresin, you may notice that batches that use it have creamier, silkier lather. Later this week I will be making soap with Rosemary Oleoresin versus without for you to try in samples. Request a comparison in your order! Don’t wait though. I only have a limited amount of samples.

If you don’t want to wait, make your own comparison batches to see the difference. And before you go off to make those tests, allow me to tell you the saponification values. Are you ready?

Rosemary Oleoresin 2%
has a saponification value of 260 mg KOH / g of Fat.
Rosemary Oleoresin 5% has a saponification value of 295 mg KOH / g of Fat.

Wow! Can you believe those numbers? I was pretty astonished myself. Those numbers are pretty high compared to what we generally deal with. See how that can make such a difference in your soap? I am getting more excited for this comparison batch. Stay tuned to see what happens!
