Abstract
A process for preparing a surfactant mixture containing magnesium in which said surfactant mixture is fluidizable. The process comprises neutralizing the surfactant with magnesium hydroxide or magnesium oxide followed by the addition of certain sugars. The resultant surfactant mixture is easily manipulated for use in detergent compositions such as concentrated light duty liquid or gel dishwashing detergent compositions.
Claims11
A process for preparing a concentrated surfactant mixture, which process comprises the steps of:
- a) forming a neutralization seat comprising from about 0.5% to about 4% magnesium hydroxide or magnesium oxide and from about 0.1% to about 5% sugar;
- and
- b) adding to said neutralization seat of step (a) from about 25% to about 45% of a surfactant acid mix;
- to thereby form a concentrated surfactant mixture which is fluidizable.
1 more element
A process for preparing a concentrated surfactant mixture, which process comprises the steps of:
- a) forming a neutralization scat consisting essentially of magnesium hydroxide, sodium xylene sulfonate, suds booster selected from the group consisting of betaines and semi-polar amine oxides, polyhydroxy fatty acid amide, magnesium chloride, propylene glycol, and sucrose;
- b) adding to said neutralization seat of step (a) from about 25% to about 45% of a surfactant acid selected from the group consisting of alkyl sulfuric acid and alkyl ether sulfuric acid;
- to thereby form a concentrated surfactant mixture which is fluidizable and which has a pH between about 6 and about 7, after treatment with organic or inorganic base.
