Filed:

Sep 3, 2002

Appl. No.:

10/233749

Inventors:

Charles Carr - Yardley PA, US
Archana Gupta - Princeton NJ, US

International Classification:

C11D017/00

US Classification:

510/421000

Abstract:

A process for the preparation of mixed ethoxylated alkyl phenol/alkyl phenol ethoxy sulfate surfactants, such surfactants, and detergent formulations incorporating the same. The mixed surfactants are more tolerant of sodium carbonate, allowing greater amounts of sodium carbonate to be used so that the amount of surfactant can be reduced resulting in overall cost savings in the resultant laundry product.

Abstract:

An article is provided including an aqueous liquid detergent, and a package for the aqueous liquid detergent which is in direct contact with the aqueous liquid detergent, wherein the package is formed from a water-soluble, film-forming material. The aqueous liquid detergent includes at least about 40% by weight of water based on the total weight of the aqueous liquid detergent, a builder comprising potassium carbonate, wherein the potassium carbonate is present in an amount of at least about 25 weight percent, based on the total weight of the aqueous liquid detergent, a first surfactant, wherein the first surfactant is an anionic surfactant, and a second surfactant, wherein the second surfactant is a nonionic or an amphoteric surfactant. The first surfactant and the second surfactant are present in a combined total amount of about 0.1% to about 25% percent by weight based on the total weight of the aqueous liquid detergent.
