Coconut oil is pretty much insoluble in water at room temperature. Since it is a mixture, it really depends on the composition as to how much of it will dissolve. Typical composition of coconut oil is:Name of Fatty AcidPercentageApproximate solubility in water at 20 °CLauric Acid45% to 52%0.055 g/LMyristic Acid16% to 21%0.02 g/LCaprylic Acid5% to 10%0.7 g/LCapric Acid4% to 8%0.15 g/LCaproic Acid0.5% to 1%9.7 g/LPalmitic Acid7% to 10%0.007 g/LOleic Acid5% to 8%< 0.001 g/LPalmitoleic AcidIn traces< 0.001 g/LLinoleic Acid1% to 3%< 0.001 g/LLinolenic AcidUp to 0.2%< 0.001 g/LStearic Acid2% to 4%0.003 g/L
"Chemical formula" refers to the atoms and their ratios in a molecule, such as H2O for water. Since oil paints are a mixture of many ingredients, they do not have a chemical formula as such. Each colour has a different "mixture" formula, or recipe. The main ingredients in artist's oil paint are siccative (drying) oil (safflower, soy, linseed, poppy, walnut, etc), pigments, and fillers (calcium carbonate, talc, silica or china clay, blanc fixe or baryte, alumina...). They may also include additional siccative such as an alkyd resin, and rheological additives (thickeners) like Bentonite clay, aluminum stearate, etc.
