Castile soap

Castile soap is manufactured from olive oil, transparent soap from decolorized fats and liquid green soap from KOH and vegetable oils. Soaps are sometimes superfatted in that they contain some free fatty acid.

Oils such as olive oil, soybean oil, or canola oil make softer soaps. Castile soap is any soap that is made primarily of olive oil. This type of soap is known for being mild and soft. 

The choice of alkali was more difficult. In Leblanc s time, the alkali was generally a carbonate (C03) or hydroxide (OH) of potassium or sodium extracted from the ashes of salt-rich plants. For example, northerners made an odoriferous soft soap by burning wood and boiling its ashes with animal fat or fish oil. In Spain, Marseilles, Genoa, and Venice, hard Castile soap was made by boiling olive oil with the ashes of seaweed and shore plants. 

For greasy films a mixture of 1 volume pro-pyleneglycol, 1 vol chloroform and powdered Castile soap dissolved in the mixt is recomr mended. It functions better when slightly warmed Refs 1) Clift fit Fedoroff, Vol 1 (1942), Chap 1, p 28. 2) E.M. Doss, JChemEduc 24, p 537... 

Spider mites can be controlled by dissolving Castile soap in water and spraying the leaves, including the underside. Repeat at two-week intervals for three applications. Caution there have been some reports of soap damaging leaves, so don t use too much. 

Aphids are a little more resistant to a simple castile soap spray, so I recommend using insecticidal soap on them. 

I have had good results combating whitefly (and to a lesser degree aphids) simply spraying the underside of the leaves with a solution of 1 tsp. liquid castile soap (such as Dr. Bronner s unscented) to 1 qt. of water. The soap breaks down the insects protective coating and they drown. The plants can be rinsed off the following day with clean water. You will want to repeat this procedure once a week for a couple of weeks to kill any pupa that survived the initial spraying and have turned into adults. 

Aphids are a little more resistant to a simple castile soap spray, so I recommend using insecticidal soap on them, such as Safer brand. These soaps contain salts of fatty acids and are quite safe to use, even within days of harvest. The directions say the soap can be left on, but I wash the leaves off the following day after application just to be safe.

This can be prepared in several different ways. Commonly dry Castile soap is dissolved in 80 per cent, alcohol in such proportions as will yield a solution well above the desired final concentration 100 grams per litre is a convenient ratio. After allowing this solution to stand at rest for several days for the deposition of undissolved matter, a quantity of the clear liquid is withdrawn (usually 75-100 c.c. per litre of final solution), and so diluted with 80 per cent, alcohol as to produce a solution which on titration with a known weight of calcium chloride solution under the standard conditions will give results in accordance with Clark s table. The calcium chloride solution is best prepared by dissolving 0-2 grams of Iceland spar in dilute hydrochloric acid excess of acid is removed by evaporation on a water bath and the solution then diluted to 1 litre with distilled water. A mixture of 25 c.c. of this solution, mixed with 25 c.c. of water, should require 7-8 e.e. of Clark s standard solution for the production of a permanent lather.

For many vegetable powders castile soap answers very well, a small quantity readily imparting the necessary consistence. Resinous powders are particularly adapted to its use. 

Ordinary soap today is simply a mixture of sodium salts of long-chain fatty acids. It is a mixture because the fat from which it is made is a mixture, and for washing our hands or our clothes a mixture is just as good as a single pure salt. Soap may vary in composition and method of processing if made from olive oil, it is Castile soap alcohol can be added to make it transparent air can be beaten in to make it float perfumes, dyes, and germicides can be added if a potassium salt (instead of a sodium salt), it is soft soap. Chemically, however, soap remains pretty much the same, and does its job in the same way.
