Patent ID: 11814468

Abstract:
This invention provides stable polyol compositions at all states and these compositions are stable for at least 24 hours, in some cases for more than 6 months. There is also provided polyol mixture compositions that may be uniformly blended under manufacturing conditions within a time period of less than eight hours, typically less than two hours, i.e., stable—polyol mixtures. The invention provides a composition and a method for making stable polyurethane foams. The polyol mixture comprises at least two polyols of different polyoxyethylene content, catalyst, at least one ethoxylated alcohol of the following formula: RO(CH2CH2O)nH, wherein R is C1-C31 linear or branched alkyl, n is an integer equal to or greater than 1; and wherein the at least one ethoxylated alcohol has a hydrophilic-lipophilic balance (HLB) value equal to or greater than about 3.7.
