Originally the term metallic soaps was only used for metal salts of fatty acids of naturally occurring animal fats (mainly tallow and lard) and vegetable fats.
Gelatin is a translucent, colorless, brittle (when dry), flavorless, edible, multifunctional protein polymer, hot-water extracted from “collagens” obtained from various animal and fish byproducts.
Citric acid is a weak organic acid found naturally in citrus fruits, especially lemons and limes. It is a colorless, crystalline solid at room temperature with the formula C6H8O7.
Benzoic acid is a white crystalline solid organic compound with the chemical formula C6H5COOH. The name "benzoic acid" is derived from gum benzoin, a resinous substance obtained from the styrax plant indigenous to South Asia.
Acetone, also known as 2-propanone, is a colorless, flammable liquid with a pungent odor and low viscosity. It is the simplest ketone, with the formula C3H6O. Acetone is miscible with water, meaning it mixes readily with water in any proportion.
Oxalic acid is the simplest saturated dicarboxylic acid with the formula C2H2O4. It is a white solid that occurs naturally in the form of a dihydrate. Anhydrous compound must be produced from the dihydrate even when manufactured industrially.
Phenol, also known as hydroxybenzene, is an organic compound with the chemical formula C6H5OH. It is a white crystalline solid at room temperature, but technical grade phenol can be a liquid due to impurities. It has a distinct odor, often described as sickeningly sweet and tarry.
Vitamin B3 is one of the vitamins of the B complex. It is also called niacin. The terms niacin or vitamin B3 are generally used as generic descriptors for both nicotinic acid and nicotinamide.
Phloroglucinol, also known as 1,3,5-trihydroxybenzene, is an organic compound with the chemical formula C6H6O3. It is colorless to beige solid at room temperature and is soluble in water, ethanol, and diethyl ether.
Pyrogallol, also known as 1,2,3-trihydroxybenzene, is a white crystalline solid with the formula C6H6O3. Pyrogallol exists in the form of colorless needles or leaflets, which gradually change color to dark gray upon exposure to air or light.
1,3-Propanediol is a clear, colorless, odorless liquid that is miscible with water, alcohols, ethers, and formamide. It is sparingly soluble in benzene and chloroform.
Butanone also known as methyl ethyl ketone, MEK, is an aliphatic ketone and, next to acetone, the most important commercially produced ketone. It is a is a colorless, low-viscosity, flammable liquid with a characteristic ketone-like odor similar to that of acetone.
