Abstract
An anti-icing composition is provided, which comprises methyl cellulose from about 5 to about 15% (v/v); propylene glycol from about 9 to about 11% (v/v); vegetable glycerin from about 9 to about 11% (v/v); isopropyl alcohol (90%) from about 42 to about 49% (v/v), and water from about 10% to about 35% (v/v). Methods of preparing and using the anti-icing composition are also described.

- isopropyl alcohol (90%) from about 42 to about 49% (v/v), and H2O from about 10% to about 35% (v/v).
A method of treating a surface to prevent icing, the method comprising applying to the surface an anti-icing composition comprising methyl cellulose from about 5 to about 15% (v/v);
- propylene glycol from about 9 to about 11% (v/v);
- vegetable glycerin from about 9 to about 11% (v/v);
- isopropyl alcohol (90%) from about 42 to about 49% (v/v), and H2O from about 10% to about 35% (v/v).
A method of making an anti-icing composition comprising methyl cellulose from about 5 to about 15% (v/v);
- propylene glycol from about 9 to about 11% (v/v);
- vegetable glycerin from about 9 to about 11% (v/v);
- isopropyl alcohol (90%) from about 42 to about 49% (v/v), and H2O from about 10% to about 35% (v/v), the method comprising:
- a) titrating isopropyl alcohol (90%) dropwise into an amount of methyl cellulose;
- b) letting the mixture of a) stand until the solution turns clear;
- c) titrating dropwise vegetable glycerin into the mixture from b);
- d) titrating dropwise propylene glycol into the mixture of step c);
- e) agitating the mixture of step d);
- f) adding water to the mixture of e), and agitating the resulting mixture until clear.
