Why is the soap derived from coconut oil so soluble?-The primary fatty acid of coconut oil is laureate, a 12 carbon chain.The more carbons in a chain the more difficult it becomes to break down the oil. One study published in the journal Cannabinoids found olive oil to be an optimal choice for extracting cannabinoids , in comparison to other solvents, like petroleum ether and naptha. Soluble in water; very soluble in alcohol, in glycerin, in chloroform, in ether, and in fixed and volatile oils; sparingly soluble in mineral oil. Relevance. Quick Wash Ethanol, also know as QWET is one of the techniques commonly employed to extract oil from cannabis. There is possible to emulgate small amount of the oil in the water solution, but it needs addition of an emulgator to the solution. The principle of miscibility helps to explain how oil does not mix with water but does mix with alcohol. Coconut Oil: Clear, white to light yellow-tan, viscous liquid. Part of Springer Nature.

Addition of a good solvent, like n-hexane, increases the solubility of oils, and the solubility temperatures are lowered. Solomon Habtemariam, in Medicinal Foods as Potential Therapies for Type-2 Diabetes and Associated Diseases, 2019. Freely soluble in methylene chloride and in light petroleum (bp: 65 to 70); very slightly soluble in alcohol; practically insoluble in water. When I say solids I’m talking about anything from salt and sugar to beetroot extract, coarse clay, and jojoba beads. Am. Oil and alcohol are miscible (can mix evenly). All the oils investigated are found to be miscible above the boiling point of alcohol even if the concentration is 98%. I use coconut oil with c02 blasted wax, just heat your coconut oil up to about 210° for 20-40 mins, once coconut oil is warm slowly stir in small amounts of wax. Solubility data are provided and collected for the pure sodium and potassium soaps. Ethyl alcohol has a specific gravity of 0.78, so it will float on water (1). In the solution the coconut oil it tends to form as a whitecolloidal matter after the addition of dilute alkali. Many health organizations advice against the consumption of high saturated fat [5,6] .
