Additives test: Tussah Silk & Aloe Vera Gel
My next to do experiments were the use of tussah silk fibers and Aloe vera Gel as additives in a specific oil recipe that I had available:
Palm: 40%
Coconut: 25%
Olive Oil: 20%
Canola Oil: 15%
a total of 3 x 500gr soaps with 2% superfat and 33% lye concentration which is 73,5gr NaOH and 148gr distilled water, 1% FO Orange Skin , while I used for the first time EDTA at 0,5% of all the ingredients (oils, water).
I'm wondering why the EDTA is one of the additives that is computed based in the entire recipe and not only based in the quantity of oils.
The first soap doesn't have any additives and was colored with a few drops of red pigment and titanium dioxide, the second one has 0.04% of oils (0,2gr) tussah silk fibers and was colored with yellow pigment and the third one has 100gr aloe vera gel (and the rest 48gr of liquid with water) while it was colored only with TD.
The three lye solutions can be seen in the photo below:
In the lye solution with tussah silk, the fibers were cut into little pieces and were dropped in water a few minutes prior NaOH. When I added NaOH the fibers started to dissolve but few of them remained intact.
In the lye solution with the 100gr aloe vera gel & 48gr water when NaOH was added the whole solution turned into a white opaque solution with few bubbles on top similar to a milky solution.
All three soaps where CPOPed at 65-70°C for 30 min when they reached gel phase:
At this point just right after the gel phase, I also tried for the first time to spray the top of the soap pastes with alcohol in order to see if this can reduce the soda ash phenomenon.
All three soaps after the gel phase, rested in room temperature for 4 hours, and then they were cut:
and are curing in the air cooled curing rack.
I have observed that the soaps with tussah silk fibers have some weird spots with different color and texture and this is maybe for the fact that I didn't strain the lye solution from the fibers that weren't dissolved.
After a week's curing all soaps don't have any soda ash on their tops at all and it seems that the alcohol spray did help on this.
So after two months I will try to feel if there are any difference between the control and the Silk and Aloe Vera gel soaps.
