Abstract
A concentrated aqueous dialkylsulfosuccinate wetting agent formulation containing at least 10% w/w of a dialkylsulfosuccinate, at least one nonionic surfactant cosolvent in an amount effective to assist in the solvation of the dialkylsulfosuccinate and water. The formulation has a low volatile organic compound content and generally has a high flash point.
Claims31
A concentrated aqueous dialkylsulfosuccinate wetting agent formulation comprising:
- (a) at least about 60% w/w of a dialkyl sulfosuccinate represented by the formula (I):
- ##STR4## wherein R.sup.1 and R.sup.2 are independently selected from an alkyl group having five to thirteen carbon atoms and X is selected from the group consisting of an alkali metal, an alkaline earth metal, ammonium or a substituted ammonium radical;
- (b) at least one nonionic surfactant cosolvent in an amount effective to assist in the solvation of said dialkylsulfosuccinate;
- and
- (c) water, wherein said formulation is substantially free of volatile organic compounds.
A concentrated aqueous dioctyl sodium sulfosuccinate wetting agent formulation comprising:
- (a) about 60 to about 75% w/w of dioctyl sodium sulfosuccinate;
- (b) about 10 to about 20% w/w of a nonionic surfactant cosolvent;
- and
- (c) about 10 to about 20% w/w water, wherein said formulation is substantially free of volatile organic compounds.
A concentrated aqueous dialkylsulfosuccinate wetting agent formulation comprising:
- (a) at least about 40% w/w of a dialkyl sulfosuccinate represented by the formula (I):
- ##STR5## wherein R.sup.1 and R.sup.2 are independently selected from an alkyl group having five to thirteen carbon atoms and X is selected from the group consisting of an alkali metal, an alkaline earth metal, ammonium or a substituted ammonium radical;
- (b) at least one non-ionic surfactant cosolvent in an amount effective to assist in the solvation of said dialkylsulfosuccinate;
- and
- (c) from about 10 to about 20% w/w water,
- wherein said formulation is substantially free of volatile organic compounds.
