Videos(no sound) of Neem Oil Liquid Soap

                                       In the end, the temperature of this batch was only 85.2℃




Followings are short films I took from my digital camera of neem oil liquid soap. This liquid soap was  made of 70% neem oil and 30% canola oil.
Neem oil  SAP Naoh=0.1387   Koh=0.194  INS=124
I tried my best to record and stir at the same time.  Sometimes the lens got fogged up by the steam of the soap batch.
Here is the receipe of this batch

neem oil      483g                                    483*0.194 =94
canola oil    208g                                    208*0.1856=38.6
Koh            132g
water        396g
  1/24/12 
total soap paste is 905g ,  make into liquid soap using ratio of 1:2.

When I decided to record this film, I had been hand mixing for over ninety minutes.  Before recording,  I could see the koh floating on top as darker brown liquid.

You can see from the shaky film that the mixture was still very soft.

The mixture looked like chocolate pudding. The smell of the neem oil was very strong.

The pot was on the stove with warm setting on.  From time to time I monitored with a digital thermoter.  The temperature was below 85℃.

Tripod you say?  That will be great if I have one.  I will try to ask my daughter for help if I do another film again.

 

These two films I couldn't separate them.  The first one seemed about the same.  The second one seemed to dry up a bit.  Slightly turn to like sugar paste.  At the end of the second film, you can see the stove setting on "warm" with full coil.

In this film you can see the texture was denser.  The paste temperature was 81℃

Finished!!  It took another 30 minutes.
