Abstract
A composition contains a polyalkylene glycol and a fatty amine ethoxylate, the fatty amine ethoxylate having non-cyclic structure of structure (I). Where R is a linear, non-cyclic carbon-containing group with that is free of nitrogen, x and y are selected from a group consisting of zero and positive values provided that the sum of x and y are in a range of 8-20.
Claims5
A composition comprising a polyalkylene glycol and a fatty amine ethoxylate, wherein the is at polyalkylene glycol is a butanol-initiated polyalkylene glycol and is at least 95 weight percent of the composition and the fatty amine ethoxylate having a non-cyclic structure of structure (I):
- where R is a linear, non-cyclic carbon-containing group with that is free of nitrogen, x and y are selected from a group consisting of zero and positive values provided that the sum of x and y are in a range of 8-20, and wherein the fatty amine ethoxylate is at least 4 weight percent relative to a combined weight of the polyalkylene glycol and a fatty amine ethoxylate.
A method for treating a polyalkylene glycol base oil, the method comprising adding a fatty amine ethoxylate to the polyalkylene glycol base oil to form a composition wherein the polyalkylene glycol is a butanol-initiated polyalkylene glycol and is at least 95 weight percent of the composition, the fatty amine ethoxylate having a non-cyclic structure of structure (I):
- where R is a linear, non-cyclic carbon-containing group with that is free of nitrogen, x and y are selected from a group consisting of zero and positive integers provided that the sum of x and y are in a range of 8-20, and wherein the fatty amine ethoxylate is at least 4 weight percent relative to a combined weight of the polyalkylene glycol and a fatty amine ethoxylate.
