Description of the Essential Oils:
Eucalyptus: It awakens the mind and opens the lungs. It helps remove exhaustion & mental sluggishness and rejuvenates the spirits of the sick. It has a pleasant aroma and is effective as a deodorant, antibacterial, antiseptic, and antimicrobial agent.

It is used for its soothing qualities on the digestive system.

It may be effective in a variety of dermatologic conditions including dandruff, acne, lice, herpes, and other skin infections.

What is Neem Oil and why use it?
Neem Oil is very effective antiseptic, anti-fungal, antibacterial, antiviral agent. Assists in the healing of skin disorders including eczema, psoriasis, rashes, burns and acne. Considered a natural insect repellent. It has a very strong odor that is often described as a blend of nut and garlic (more like really bad garlic and something dead – fortunately this scent cures out). Rich in essential fatty acids, triglycerides, vitamin E & calcium; known to smooth wrinkles, reduce eczema and acne, stimulate collagen and relieve dry skin.

Scent Blend 3.75 oz Total: 1.25 oz of each: Eucalyptus, Peppermint, Tea Tree.

95 oz Batter/Colors/Salt/EO Blend:
15 oz soap + 7 oz PH Salt, BB Apple Green LabColor
15 oz soap + 7 oz PH Salt, BB Aqua Blue LabColor  + Ultraviolet blue
37 oz soap + 14 oz PH Salt, BB TD White
ITP swirl: White base, with green & blue added.
Top with little birds & hearts one on each bar.

Soap at 130 degrees, do not stick blend. Pour off 8+ oz for embeds before adding Neem Oil & Salt.


The Reality:
Soaped the Lye & oils at 122 & 124 degrees.

Poured off 8 oz for embeds, then added the Neem Oil & EO Blend and separated into 3 containers. Added colors.

Sadly, with the dark brown of the Neem Oil, it distorts all the colors:


Clockwise: blue (should morph to blue), green & white

I added the salt and poured the green & blue into the white for an In The Pot swirl. Poured into 6-bar and 9-bar mold and added heart & bird embeds.

Unfortunately, it looks very boring, but the discolor from the Neem Oil should dissipate:


The Cut/ Un-molding:
I am quite disappointed that the bright green and blues did not come through. In a test batch with Neem oil (see March 27, 2017 blog here), and the colors appeared in a couple weeks, but not these. After 2+ weeks they still looked like concrete, so I gave up. Surprisingly, 3+ weeks into the cure they all turned to a lovely shade of pale green.

Only 2 soaps from the 9-bar mold have a hint of the colors I used:


Not captured very well in these photos is the pale green color of all the soap.


Soaps from the 6-bar mold have a hint of Ultraviolet Blue trying to get through, but can’t quite make it.

You can see more of colors trying to come out on the back side of the 6-bar mold with impression mat:


Leftovers were put in a leaf mold:

I really like the cute little embeds on top and the impression mat on the bottom – I should have used the mat for all the bars. I obviously need, much, much more color next time and I need to keep in mind the green-brown hue from the Neem oil, plus the pink from the PH salt when I plan the color palette.
