Uses
Because ceresin has a high melting point, forms stable emulsions and is colorlss and odorless, it is used in such cosmetic products as lipsticks, creams and hair stick. As examples of other applications, it is used together with paraffin for mimeographpaper, shoe polish and lustering agents.

SOLUBILITY | : | Properties Ceresin occurs as colorless or white,crystalline masses, having a faint, characteristic odor and no taste.Ceresin has an external appearance and physical and chemical characteristics similar to paraffin, but its molecular weight,specific gravity, viscosity, hardness and melting point are higher 75 C while Utah Wax often has a melting point around 90 C. Ceresin is formed from needle shaped or short plate shaped microcrystals. It is soluble in carbon disulfide, petroleum ether, toluene, benzene and chloroform but only sparingly soluble in ethanol.(Ref. 0019> |

Origin : The name ceresin is formed from two latin words : cere which meaning ""beeswax ""and sin meaning ""without"". The name thus signifies that it is a waxy substance that is unlike beeswax.Ceresin is produced from ozocerite. The first ceresin which had commercial value was made by Pilt and Ujhelji in 1870 by first treating ozocerite with sulfuric acid and then refining it using activated charcoal. In addition to the substance made by refining ozocerite, ceresin sometimes refers to a mixture of paraffin and ozocerite and in Pharmacopoea Helvetica, ceresin is called paraffin.The major constituents of ceresin are isoparaffins corresponding to C

A method of manufacture: Some of the major production areas for ozocerite are Galicia in southern Poland, around Lake Baikal in Russia and Utah and Texas in the United States. In these areas, ozocerite is found as irregular mineal veins or as a black mass in clay strata. After being dug out, the ozocerite is heated to melt it and any earth or rock is removed. If necessary, it is heated to 115-120

C to remove any moisture and then treated with sulfuric acid or fuming sulfuric acid. After neutralization, it is decolorized using activated charcoal or silica gel and filtered. If decolorizing is not sufficient, it is repeatedly treated with sulfuric acid and subjected to adsorption filtration to produce more refined ceresin. Continued to Metabolism
Another mrthod of producing cersin involves dissolving ozocerite in ligroin, treating with activated clay and then removing the high boiling point fraction. Ceresin available on the market may be mixed with paraffin or a small amount of carnauba wax may be added to it to raise the melting point. (
