Abstract
The present invention is directed to stabilized surfactant containing solutions, stabilized or inhibited against oxidative attack, comprising an amphiphilic antioxidant component.
Claims21
-20. (canceled)
A composition comprising:
- a) an amphiphilic antioxidant component,
- b) a surfactant component, and
- c) an oxidant component,
- wherein the amphiphilic antioxidant component comprises at least one amphiphilic antioxidant and at least one hydrophilic antioxidant booster, wherein the molar ratio of amphiphilic antioxidant:booster is at least 1:1,
- wherein the surfactant component comprises at least one organic surfactant,
- wherein said oxidant component comprises at least one oxidant, and
- wherein the amphiphilic antioxidant component is present in an amount sufficient to improve the stability of the surfactant against oxidative attack.
4 more elements
A method for preparing a stabilized solution having an organic surfactant and an oxidant, which comprises:
- 1) preparing a stabilized surfactant composition by combining a surfactant component with an amphiphilic antioxidant component;
- 2) combining the stabilized surfactant composition with an oxidant component;
- 3) and adding an alkali agent to the combination from step 2) in an amount to adjust the pH to a value of at least 6,
- wherein the surfactant component comprises said organic surfactant,
- wherein the oxidant component comprises said oxidant,
- wherein the amphiphilic antioxidant component comprises at least one amphiphilic antioxidant and at least one hydrophilic antioxidant booster, wherein the molar ratio of amphiphilic antioxidant:booster is at least 1:1, and
- wherein the amphiphilic antioxidant component is present in an amount sufficient to improve the stability of the surfactant against oxidative attack in the solution containing said oxidant.
4 more elements
A method for improving the stability of a solution containing a surfactant and an oxidant, comprising incorporating an amphiphilic antioxidant component in said solution,
- wherein the amphiphilic antioxidant component comprises at least one amphiphilic antioxidant and at least one hydrophilic antioxidant booster, wherein the molar ratio of amphiphilic antioxidant:booster is at least 1:1, and
- wherein the amphiphilic antioxidant component is present in an amount sufficient to improve the stability of the surfactant against oxidative attack in said solution.
