Thanks DeeAnna for the information. Regarding the last question, I've been making soap since 1993. I've read so much about soap and soap chemistry from different books downloaded from the internet, forums and so on. Any conclusion that I came up with is the result of both reading and experimenting. Anyways, I am always open for any corrections or new insights.. Regarding Lemon, it seems that there's something in the Lemon juice - - other than water - that dissolves or soften the soap. Yes, maybe it's citric Acid. Maybe it's something more. I don't know really for sure. I always add Lemon juice to soap. I'd want to get the benefits of it in soap, and also I like how it helps with easing the process all together. I think yes it's true that essential oil of Lemon is not a Triglyceride. But can you really be sure that the content of Lemon juice is really 0 or triglyceride free? You also mentioned that Naoh reacts with Citric Acid which is (an acid).. what would the result be of reacting an alkali such as Naoh with an Acid like citric other than soap..? ( C3H5O(COOH)3 +3NaOH>Na3C3H5(COO)3 +3H2O ) . There's a tiny little soapy particle in their, don't you think? cheers After reading your comment again, I see that much of it actually goes along with what I've mentioned such as ph dropping and so on. Regarding your first comment, the time of adding Lemon juice and the method used really makes a deference. I know this from experiment.. It's different if the juice (that might contain oil by the way..) is added while the Naoh has neutralized with acids or not.. Thanks RobinRogers for your kind question. I usually add the juice of 5 lemons per 3 kilos of soap. I add half of the juice during the final stages of screening with salt. Then I add the rest after I make sure that the salt-water has washed away any excessive Naoh and other impurities. This is what I "think" that happens by observation and result. When the juice is added during salting-out, the water part in the juice joins the salt-water below. And if there's any remaining of an Acid that came from the juice, it joins the soap layer above.. Of course it's obvious that some of the lemon oil joins the soap, because the soap smells Lemon afterwards.. Another thing, is that the other part of the juice is added after I make sure that the excessive Naoh has left the soap. I switch from boiling to steam-bathing. I place the soap in a water or steam bath allowing the excessive water to evaporate slowly and the soap to neutralize further. Also during boiling-salting out, and after I add the juice, I drop the lemons with its peel in the pan, so that I can extract any oil from the peels. The heat and the salt in the water helps in "expelling?" the oil in the peels, and if there's any in the inside of the lemons.
