Abstract
Thixotropic compositions and methods to produce thereof comprising ethylcellulose, triacylglycerol oil and non-ionic surfactant are provided. The ethylcellulose concentration is in the range of 1-15% and the surfactant to oil ratio is in the range of 40:60 to 60:40.
Claims20
A thixotropic composition comprising ethylcellulose in combination with a triacylglycerol oil and a non-ionic surfactant, wherein the ethylcellulose concentration is in the range of about 1-15 wt % and the combination of the triacylglycerol oil and surfactant is in the range of about 85-99 wt %, wherein the surfactant to oil ratio is in the range of about 40:60 to 60:40 (w/w) surfactant to oil.
A method of preparing a thixotropic composition comprising:
- a) combining ethylcellulose in an amount ranging from 1-15% by weight with a triacylglycerol oil and a non-ionic surfactant, wherein the combination of the triacylglycerol oil and surfactant is in the range of about 85-99 wt % and wherein the ratio of surfactant to oil is in the range of about 40:60 to 60:40 (w/w) to form a mixture;
- b) heating the mixture until the ethylcellulose is solubilized;
- and
- c) allowing the mixture to cool to form a thixotropic composition.
