<p>Waxes prepared from hydrogenated plant oils, such as castor, palm, and soybean, are used to prepare water based emulsions. The inventive waxes, obtained from naturally derived, renewable resources, were emulsified under anionic, cationic and nonionic conditions, producing emulsions having a soli ds content up to about 45% solids. When used to coat fibrous cellulosic article s, such as paperboard, the emulsions~ performance was similar to emulsions containing petroleum-derived waxes. The inventive waxes have a low iodine value (between 2-5), and melting points between approximately 120-200 degree s F (Mettler Drop Point). These waxes comprise a triglyceride whose fatty acid s are perdominantly stearic acid or ricinoleic acid. The inventive waxes are u se as an alternative to petroleum-derived, or expensive naturally-occurring wax es in the manufacture of emulsions used in coatings, polishes, adhesives, paper products, paperboard and other manufacturing operations.</p> |
