Abstract
A cellulosic composition of a cellulosic such as ethyl cellulose, a surfactant such as polyoxyethylene sorbitan monolaurate and a heat stabilizer such as triaryl phosphite can be mixed with an oil extender to form a hot melt composition which does not discolor upon extended heating at elevated temperatures.
Claims21
A hot melt composition comprising a cellulose ether or cellulose ester, an oil extender, an amount of a surfactant sufficient to measurably reduce the oil exudation from a solidified composition of the cellulosic and oil extender or visually improve the compatibility of the components in the solidified composition and an amount of a heat stabilizer sufficient to reduce the discoloration of the hot melt composition upon extended heating at a temperature sufficient to form a liquid solution of the hot melt composition.
A cellulosic composition comprising from about 60 to about 99 weight percent of a cellulose ether or cellulose ester from about 0.5 to about 35 weight percent of a surfactant and from about 0.5 to about 10 weight percent of a heat stabilizer, said weight percents being based on the total weight of cellulosic, surfactant and heat stabilizer.
