Abstract
Provided herein are detergent formulations which can effectively suppress efflorescence in unit dose detergent packs. In accordance with one embodiment, the detergent formulations comprise an alkyl ethoxysulfate component having an alkyl chain length of about 12-18 carbon atoms and about 2-9 moles of ethylene oxide and a cation, an alcohol ethoxylate component having an alkyl chain length of about 12-18 carbon atoms and about 5-9 moles of ethylene oxide, high fructose corn syrup, and a liquid carrier.
Claims17
A unit dose detergent product having an improved profile against efflorescence, comprising:
- a container formed from a water-soluble or water-dispersible film material, the container having one or more compartments;
- and
- a liquid composition entrapped in the one or more compartments of the container;
- wherein the liquid composition consists of:
- (a) from about 2% to about 35% of an anionic surfactant selected from an alkyl ethoxylated sulphate, an alkyl propoxy sulphate, an alkyl sulphate, a linear alkylbenzene sulfonic acid or a salt thereof, or a mixture thereof;
- (b) from about 2% to about 30% of a non-ionic surfactant selected from an alcohol ethoxylate, an alcohol propoxylate, or a mixture thereof;
- (c) from about 1% to about 70% of a mono-, di- or oligo-saccharide, and
- (d) less than about 18% of a yellow color reducing agent,
- the yellow color reducing agent being sodium sulfite;
- wherein all of the % above are based on the weight of the liquid composition;
- wherein the balance of the liquid composition is a solvent system consisting of water, glycerin, a C3-C7 alkyl glycol, and optionally, polyethylene glycol (PEG) in an amount from about 10% to about 45% by weight of the liquid composition;
- and
- wherein the component (c) is present in an amount greater than 15% based on a combined weight of the component (c) and polyethylene glycol, when the PEG is present in the liquid composition.
