Quality assurance of raw materials used in the production of a veterinary topical analgesic was completed for Hobart Laboratories. Creosote, glycerin, guaiacol, menthol, methyl salicylate, peerless clay, SnoBrite clay, propylene glycol, sorbitol, and methyl guaiacol were characterized by techniques including: gas chromatography, density determination, melting point, boiling point, high pressure liquid chromatography, odor tests, solubility, ignition residue, chloride content, infrared spectroscopy, sulfate content, optical rotation, non-volatile matter, titrations, ferric chloride tests, moisture content, mesh assays, heavy metal content, and flame tests. After the purity of each of the raw materials was validated by our testing, certificates of authenticity were produced and presented to Hobart Laboratories. These certificates indicated that each of the raw materials’ characteristics were within the acceptable range for industry. In addition to laboratory experience, the chapter gained a monetary donation from Hobart Laboratories upon receipt of the certificates.
