In the lab: Playing with oils

This project is just to get an idea of which oil does after saponification. Each cupcake is 100% of one type of oil, plus distilled water and lye. I’ve rewritten this post so the information is a little more organized.

1/12 - individual oils

1/12 – individual oils

The re-write was inspired by this post that Jane pointed out to me on the Soaper’s Retreat Facebook page. Zen Soaps did a single oil swap back in 2003. They have 25 different oils to my 11. Very interesting, and I’ve bookmarked it for future reference. Thank you, Jane!

On to the experiment!

1/13 - Almond oil

1/13 – Almond oil

1. Almond oil – Palmitic 7, Oleic 71, Linoleic 18

After 5 hours: Traced quickly without any foaming or bubbles. An off white color. Very soft, but forming to the mold.

First 24 hours: A soft form of a cupcake, and can be partially lifted out of the cup. Very moist/oily to the touch. Too soft to leave mold.

 

1/13 - avocado oil

1/13 – Avocado oil

2.       Avocado Oil – Palmitic 20, Stearic 2, Oleic 58, Linoleic 12

After 5 hours: Slow to trace, without any foaming or bubbles. A pale yellow color, darker in some places. Very soft, but forming to the mold.

First 24 hours: A soft form of a cupcake, and can be partially lifted out of the cup. Very moist/oily to the touch. Too soft to leave mold.

1/13 - canola oil

1/13 – Canola oil

3.       Canola Oil – Palmitic 4, Stearic 2, Oleic 61, Linoleic 21, Linolenic 9

After 5 hours: Still liquid and not forming to the mold yet.  Will probably take one of the longest to harden. Yellow in color.

First 24 hours: Sweating and still very oily. Still has no form. Could be poured out of the mold.

 

1/13 - castor oil

1/13 – Castor oil

4.       Castor Oil – Ricinoleic 90, Oleic 4, Linoleic 4

After 5 hours: Weird. I don’t know how to describe it, but it’s like a hard surface, but oily center. Just from looking at it and squeezing the silicone cup, not exactly sticking my finger into it. Edges are off white, but the center is a pale yellow, like it’s still liquid in the middle.

First 24 hours: A hard cup cake. I pressed my finger into the top, but it left no impression. It looks translucent. Hard enough to leave the mold.

1/13 - cocoa butter

1/13 – Cocoa butter

5.       Cocoa Butter – Palmitic 28, Stearic 33, Oleic 35, Linoleic 3

After 5 hours: This is the first time I’ve worked with cocoa butter and O. M. G. -it smells divine! I’m really looking forward to working with this butter some more. A pale brown in color and has the cocoa scent. One of the first to begin hardening.

First 24 hours: A hard cup cake. I pressed my finger into the top, but it left no impression. It’s still a pale brown share, but also showing some ash on top. The scent remained through saponification. Hard enough to leave the mold.

1/13 - hemp seed

1/13 – Hemp Seed oil

6.       Hemp Seed Oil – Palmitic 6, Stearic 2, Oleic 12, Linoleic 57, Linolenic 21

After 5 hours: The hemp seed oil has me baffled. It’s sweating. I have no idea why. I didn’t touch it, but it looked like oily sweating. When I was mixing it, it foamed, which is probably why the top is so bubbly looking. I tapped it, hoping to unlock some of the bubbles. It’s a yellowish-green in color.

First 24 hours: It stopped sweating, and starting to form, but still a bit soft to touch. Weird discoloration – like a darker green shade. Not sure if it’s because the oil was from August (shelf life of 6 months) and was sitting out (needs to be refrigerated); it might be beginning to go rancid. I’ll redo this test with a fresh bottle of hemp seed oil another time. Too soft to leave mold.

1/13 - olive oil

1/13 – Olive oil

7.       Olive Oil – Palmitic 14, Stearic 3, Oleic 69, linoleic 12, Linolenic 1

After 5 hours: Still liquidy, and was slow to go to trace. A pale yellow in color.

First 24 hours:  Still very soft and wont disengage from the cup to show that its forming into a harder bar. Would be gloppy if poured from mold.

 

1/13 - palm oil

1/13 – Palm oil

8.       Palm Oil – Myristic 1, Palmitic 44, Stearic 5, Oleic 39, Linoleic 10

After 5 hours: Already beginning to harden. An off-white in color.

First 24 hours: A hard cup cake. No impression when pressing a finger into the top, but leaves a chalky residue on my finger. Hard enough to leave the mold.

 

1/13  - Rice Bran oil

1/13 – Rice Bran oil

9.       Rice Bran Oil – Myristic 1, Palmitic 22, Stearic 3, Oleic 43, Linoleic 26

After 5 hours: A pale brownish color. It was foamy going to trace, and still looks “ricey” and wet.

First 24 hours: A soft form of a cupcake, and can be partially lifted out of the cup. Very moist/oily to the touch. Too soft to leave mold.

 

1/13 - Safflower oil

1/13 – Safflower oil

10. Safflower Oil, high oleic – Palmitic 5, Stearic 2, Oleic 77, Linoleic 15

*This may not be an accurate observation since the amount of oil was 25 grams to 10 grams of water/lye solution because I ran out of water/lye. This is oil heavy.

After 5 hours: An off white color and traced quickly and seems to be setting up nicely.

First 24 hours: Still very soft and doesn’t disengage from the side of the cupcake yet. It looks a bit “ricey”. If poured from mold, it would be gloppy.

1/13 - Shea butter

1/13 – Shea butter

11.   Shea Butter – Palmitic 5, Stearic 40, Oleic 48, Linoleic 6

After 5 hours: Already beginning to harden and has a beautiful white color.

First 24 hours: A hard cup cake and still very white in color. Hard enough to leave the mold.

 

 

Clara on the Soaper’s Retreat asked me: Interesting experiment. Love to hear how it all compares in the end. At what % did you superfat? What was the hemp soap ‘sweating’? Oil or water?

5%. I calculated each oil on SoapCalc, then added it to my “spreadsheet” below. Since my scale doesn’t have decimal for grams or milliliter, I had to round up on the water and lye. Two of the oils I have on hand I didnt test for because the difference in lye was too much to add to the rest of the batch. As for the total column, I couldn’t go over 57 grams, otherwise it would overflow my cupcake mold. 🙂

"spread sheet"

“spread sheet”

The hemp seed oil cup looked oily, but I didn’t do a touch test to find out.

I’ll continue to monitor the 11 oils and update with any changes, or how long it takes some of the others to finally harden up.
