The BUTYL STEARATE molecule contains a total of 68 atom(s). There are 44 Hydrogen atom(s), 22 Carbon atom(s) and 2 Oxygen atom(s). A chemical formula of BUTYL STEARATE can therefore be written as:

C22H44O2

The chemical formula of BUTYL STEARATE shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type.

The above chemical formula is the basis of stoichiometry in chemical equations, i.e., the calculation of relative quantities of reactants and products in chemical reactions. The law of conservation of mass dictates that the quantity of each element given in the chemical formula does not change in a chemical reaction. Thus, each side of the chemical equation must represent the same quantity of any particular element based on the chemical formula.

On the basis of end use, Butyl Stearate market can be segmented into the food industry, beverage industry, cosmetics industry, textile industry, personal care, paper industry and metal industry. The food industry can be further sub-segmented into baked goods, confectionery, desserts, and gelatin. Similarly, beverage industry segment can be further sub-segmented into alcoholic and non-alcoholic beverages. Due to its popularity and large applications in food and cosmetics industry, these two industries holds the largest share in terms of volume sales as compared to other industry.
