Abstract
The present invention includes a composition comprising an enriched mixture of α-sulfofatty acid esters. Increasing the concentration of specific chain length α-sulfofatty acid esters, relative to the proportions of the other chain lengths, allows the detergent compositions to exhibit an improved cleaning performance while simultaneously cleaning a wide variety of materials.
Claims27
A composition, comprising a broad cut of C10, C12, C14, C16 and C18 α-sulfofatty acid esters comprising methyl ester sulfonates derived from natural fats or oils and having an enriched C16 or C18 α-sulfofatty acid ester concentration.
A detergent composition, comprising at least about 15 weight percent of a mixture of C12, C14 and C16 methyl ester sulfonates and having a C16-enriched α-sulfofatty acid ester concentration.
A detergent composition, comprising at least about 35 weight percent of methyl ester sulfonates comprising:
- a first methyl ester sulfonate comprising a mixture of different chain lengths;
- and
- a second methyl ester sulfonate comprising at least about 35 weight C16 chain lengths.
A composition, comprising:
- about 60 to about 40 weight percent methyl ester sulfonate comprising a mixture of chain lengths;
- and
- about 40 to about 60 weight percent methyl ester sulfonate consisting essentially of C16 chain lengths.
A method for making a detergent composition, comprising:
- providing a mixture of α-sulfofatty acid esters with a C16 enriched concentration;
- and combining the mixture of α-sulfofatty acid esters with at least one other detergent component.
A method for making a detergent composition, comprising:
- providing a methyl ester feedstock comprising methyl esters having a C16 enriched concentration;
- sulfonating the methyl ester feedstock to obtain a C16 enriched methyl ester sulfonate;
- and
- combining the methyl ester sulfonates with at least one other detergent component.
