Lime Zest Soap

After I made the Lemon Zest soap, I decided I also needed to make a Lime Zest soap. I used some Bay Rum Fragrance Oil to help scent the soap because so many masculine blends contain lime. I hope you enjoy this soap as much as I do!

Recipe in ounces:

16 oz wt Hydrogenated Soybean Oil (shortening)
16 ounces wt Coconut Oil
8 ounces wt Grapeseed Oil21 fl oz Water (I used Reverse Osmosis Water)
8.38 ounces wt Sodium Hydroxide

0.5 oz wt Bay Rum Fragrance Oil
0.5 oz wt Lime Essential Oil

0.695 oz wt Lime Zest (Zest from 5 Limes, does not have to be exact)

Zest limes. I used a fine Microplane / Zester to zest the limes. Set aside. No pith! The pith is the white part under the green. We only want the essential oil holding zest.

Weigh the Bay Rum Fragrance Oil and Lime Essential Oil into a small beaker and set aside.

Measure fixed oils on your scale. Add lime zest to fixed oils then warm on the stove or in the microwave. I melted the oils in the microwave. Add sodium hydroxide to the water. Mix well.

Combine oils and lye solution. Stir until thin trace. Don’t be alarmed when the soap turns a vibrant neon orange when beginning to mix the oils and lye solution together. Upon light trace, add the scenting oils. Stir well. Pour soap into molds. I used a soap mold that we have in our testing kitchen. Allow to sit until soap is firm.

The next morning cut into bars. Stack to allow good air circulation. Allow to cure for several days before using. Longer curing will result in a harder bar.

I added the lime zest to the oils before melting the oils to allow some of the lime oil in the zest to infuse into the oils. This allowed a nice triple touch of lime in the final soap.

Like the Lemon Zest Soap, as I was beginning to mix the lye solution and oils together and the mixture turned a bright orange. After resting for 24 hours in the mold, I cut the soap and have watched the color change from a pale orange color to a dirty spring green yellow color.

What can you do with the juice from the limes that have been zested? Check the blog tomorrow and I’ll show you!

The Lime Zest soap samples have been sent to the Shipping Department to send out in orders.

About Andee

Director of Happiness. I'm a thirty-something soap snob. I've grown up with handmade soaps, and I love them! I really like making lotions, soaps, and perfumes. I adore mixing scents to come up with something new. My favorite scent is either Wicked or Cotton Candy. I tend to hoard fragrances, I even have an Earl Grey Tea from the MMS catalog. I won't tell you how old it is, but it sure is good!
