Abstract
Anionic surfactant compositions containing alkoxylated amines and having enhanced detergent performance. The compositions may be formulated with anionic surfactants such as alkylbenzene sulfonates having cations that may be exchanged with, for example, ethoxylated amine and/or ethoxylated ether amine to form a salt.
Claims18
A surfactant composition, comprising:
- a neutralization product that is formed within said composition from at least one anionic surfactant acid and at least one ethoxylated surfactant, said ethoxylated surfactant being at least one ethoxylated ether amine thereof;
- and
- a neutralizing compound, said neutralizing compound being employed in conjunction with said ethoxylated surfactant to neutralize said anionic surfactant acid;
- wherein said ethoxylated surfactant is present in an amount less than sufficient to completely neutralize an amount of said anionic surfactant acid present;
- and wherein said neutralizing compound is present in an amount sufficient to partially neutralize an amount of said anionic surfactant acid present.
2 more elements
A surfactant composition formed from components comprising:
- a neutralization product formed within said composition from about 8% to about 35% of the surfactant actives by weight of at least one alkylbenzene sulfonic acid surfactant and from about 8% to about 35% of the surfactant actives by weight of at least one ethoxylated surfactant, said ethoxylated surfactant being at least one ethoxylated ether amine,
- from about 15% to about 55% of the surfactant actives by weight of a nonionic surfactant, wherein said nonionic surfactant comprises at least one of nonylphenol ethoxylate, alcohol ethoxylate, ethylene oxide/propylene oxide block copolymer, or a mixture thereof;
- from about 10% to about 90% water by weight of total weight of said composition;
- and
- from about 0% to about 9% neutralizing compound by weight of total weight of said composition, said neutralizing compound being employed in conjunction with said ethoxylated surfactant to neutralize said alkylbenzene sulfonic acid surfactant, and wherein said neutralizing compound comprises at least one of alkanolamine, alkylamine, ammonium hydroxide, sodium hydroxide, potassium hydroxide, or mixture thereof;
- wherein the total active surfactant concentration is from about 10% to about 90% by weight of total weight of said composition;
- and
- wherein said ethoxylated surfactant is present in an amount less than sufficient to completely neutralize the acid functionality of an amount of said alkylbenzene sulfonic acid surfactant present;
- and wherein said neutralizing compound is present in an amount sufficient to partially neutralize an amount of said alkylbenzene sulfonic acid surfactant present.

A surfactant composition formed from components comprising:
- a neutralization product formed within said composition from at least one anionic surfactant acid and at least one ethoxylated ether anime surfactant;
- at least one nonionic surfactant;
- propylene glycol;
- at least one neutralizing compound, said neutralizing, compound being employed in conjunction with said ethoxylated ether anime surfactant to neutralize said anionic surfactant acid;
- and
- substantially no water;
- wherein said components are present in amounts effective, such that said surfactant solution exists as a substantially homogenous liquid phase at about 40° F.;
- and
- wherein said ethoxylated ether anime surfactant is present in an amount less than sufficient to completely neutralize an amount of said anionic surfactant acid present;
- and wherein said neutralizing compound is present in an amount sufficient to partially neutralize an amount of said anionic surfactant acid present.
