The application of waxes for any particular industries depends on their properties. In this study the two plant waxes namely Carnauba and Candelilla waxes had been studied for their properties like melting point, needle penetration, drop melting point, flash point, viscosities and densities. The testing were carried out as per ASTM standards. These properties were correlated with the results obtained from the DSC and FT-IR data. Keywords: Carnauba wax, Candelilla wax, FT-IR, DSC, Conventional properties. I. INTRODUCTION Natural waxes are unique mix of long-chain, linear and even-numbered aliphatic mono-esters. Partially varying amounts of linear hydrocarbons (candelilla), free wax alcohols respectivly polycosanoles (carnauba wax) and other ingredients like phytosterols, natural resins are also present.[1]Carnauba wax is used in the manufacture of polishes for floors, automobiles, furniture , shoes, etc.. It is used in candles to raise the melting point; in carbon paper; and in a variety of moulded products. Articles published by scientific men in technical and trade journal reveal a curious lack of accurate information about this wax in any stage of its production or in any form other than that in which it appears on the market. The actual production of carnauba wax is exceedingly crude. The original native methods of production have been little improved. The harvesters go forth into the farms armed with a sharp sickle-like knife fastened to the end of a long pole. With this long-handled knife they cut the desired number of leaves from the trees. Harvesting takes place from July to January; the time varies in different localities, depending primarily upon rainfall.[2,4] Candelilla wax is a yellowish-brown hard, brittle, lustrous solid with an aromatic odour when heated. It consists primarily of odd-numbered saturated straight- chain hydrocarbons (C29 to C33), together with esters of acids and alcohols with even-numbered carbon chains (C28 to C34). The most abundant n-alkane, C31, comprises more than 80% of total n-alkanes. Free acids, free alcohols, sterols, neutral resins, and mineral matter (<1%) are also present.[3] Candelilla wax may be obtained from several species of Euphorbiacea; the primary source is Euphorbia antisyphilitica. The plant grows as a bush or shrub in dense stands, principally in the Chihuahuan desert in north eastern Mexico. The plant consists of numerous slender, leafless, cylindrical stalks covered with a powdery wax that gives the plant a blue-green colour.[4] The Candelilla wax is used in Textile industry, Leather industry, Casting, Precision electroplating and Automobile for coating. It is also used for manufacturing Greases, adhesive agents, Lipstick and chewing gum. II. EXPERIMENTATION AND OBSERVATIONS: The DSC of Carnauba and Candelilla waxs were carried out using ASTM D 4419. The experiment has been done using aluminium container heated at a controlled rate of
