First Claim
Patent Images
1. A monophasic liquid composition comprising:
- a. at least three antioxidants consisting of a first antioxidant that is a synthetic phenolic compound not having Formula (I), a second antioxidant selected from the group consisting of phenolic acid and derivatives, ascorbic acid and derivatives, tocopherols and derivatives, lecithin, bioflavonoid, and terpenoid; and
a third antioxidant having Formula (I);
wherein;
R1, R2, R3 and R4 are independently selected from the group consisting of hydrogen and an alkyl group having from 1 to about 6 carbons; and
R5 is an alkoxy group having from 1 to about 12 carbons;
b. a polar solvent; and
c. a nonpolar solvent, wherein the two solvents form a substantially homogenous liquid.

33. A process for manufacturing a monophasic liquid composition, the process comprising:
-
a) heating a vegetable oil to a temperature from about 40°
C. to about 90°
C. and then combining it with monoglyceride;b) combining the vegetable oil mixture of (a) with 6-ethoxy-1,2-dihydro-2,2,4-trimethylquinoline while maintaining the temperature and agitating to form a 6-ethoxy-1,2-dihydro-2,2,4-trimethylquinoline-oil matrix; c) sequentially combining the matrix of (b) first with tertiary butyl hydroquinone followed by lecithin while maintaining the temperature and agitating, wherein lecithin is dissolved in the oil matrix; d) dissolving propyl gallate in a solvent selected from the group consisting of glycerin and propylene glycol; e) combining the product of (d) with the product of (c) while maintaining the agitation and temperature for a time sufficient such that a substantially homogeneous liquid is produced.
