Abstract

Provided are amine-neutralized anionic surfactants and their use in detergent formulations. The amine-neutralized anionic surfactants are of the formula I, as described herein.

First claim

What is claimed is:

1. A unit dose laundry detergent package comprising: a water soluble polyvinyl alcohol pouch, and
a detergent formulation,
wherein the detergent formulation is encased in the water soluble polyvinyl alcohol pouch; and
wherein the detergent formulation comprises 24 to 40 wt % of an amine-neutralized anionic surfactant of formula I:

wherein R 1 is C 4 -C 14 alkyl, and M is an aminoalcohol compound which is 2-amino-2-hydroxymethyl-1,3-propanediol.

2. The surfactant of claim 1 , wherein R1 is in the 4-position of the phenyl ring.

3. The surfactant of claim 1 , wherein R1 is liner C10-C13 alkyl.

4. The detergent packet of claim 1 , wherein R1 the detergent formulation further comprises fatty acid salts, one or more additional surfactants, one or more solvents and water.
