Cellose Acetate/ Butyrate Oil-Based Paint Formulation (Developmental)

1. Commercial oil-based paint 2. Cellulose acetate/butyrate (binder) in 80% (vol) butanol :20% (+) carvone (oil of dill). and methyl ester derivative of castor oil (vehicles). Not dry to the touch after 30 minutes at 21 deg.C. The tradition of oil-based vibrant color is retained.

I am hoping this novel oil-based paint formulation will be employed by painters that prefer the oil-based paints.  The methyl ester of castor oil is sold by Caschem ( Bayonne , N.J., USA) under the tradename of" Flexrecin P-1".  It can also be prepared using traditional transesterification ( biodiesel) conditions.

NO turpentine , toluene solvents are utilized. The butanol is far less harmful (also biodegradable) for large-scale paintings than the aforementioned solvents. The cellulose acetate/ butyrate ester binder is bio-degradable in waste disposal  matters along with the castor oil derivative.

I am using bristol foundation in the image without gesso use.  For actual paintings, an undercoat of gesso should be used.

From Wikipedia:
n-Butanol or n-butyl alcohol or normal butanol is a primary alcohol with a 4-carbon structure and the chemical formula C4H9OH. Its isomers include isobutanol, 2-butanol, and tert-butanol. Butanol is one of the group of "fusel alcohols" (from the German for "bad liquor"), which have more than two carbon atoms and have significant solubility in water.[6]
n-Butanol occurs naturally as a minor product of the fermentation of sugars and other carbohydrates,[7] and is present in many foods and beverages.[8][9] It is also a permitted artificial flavorant in the United States,[10] used in butter, cream, fruit, rum, whiskey, ice cream and ices, candy, baked goods and cordials.[11] It is also used in a wide range of consumer products.[8]
