Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to builder-containing liquid detergent compositions for laundry and general use that exhibit stability against phase separation.

[Conventional liquid detergent compositions with 1 builders have been well received by consumers because they are easy to store, portion, and measure, and do not clump like some granular detergent products, making them durable during long PJIs. This is because it can harden only when stored or when moist. The main disadvantage of builder-based liquid detergent compositions is their high cost compared to granular detergent products. The cost of builder-loaded liquid detergents is due to the difficulties in producing a homogeneous builder-loaded liquid detergent composition.

Bilgoo liquid detergent compositions currently on the market typically include one or more synthetic detergents using an aqueous medium and builder liquid detergent compositions containing an inorganic bilgoo such as potassium polyphosphate. A major problem is preparing a strong solution containing sufficient detergent and builder to give the desired effect to products used for washing soiled clothes and other household cleaning tasks. Achieving a homogeneous liquid system with sufficient concentrations of detergent and builder requires complex formulations with a number of ingredients, including inert cleaning ingredients such as hydrotropes, polymeric stabilizers and thickeners. It is. These inert cleaning ingredients contribute little, if any, to the effectiveness of the liquid detergent and may in fact even be detrimental to the cleaning effectiveness. Inert cleaning ingredients increase the cost of formulation and are therefore of value only when the solution concentration of detergent and builder is high.

[Problems to be Solved by the Invention] The present invention provides a builder-containing liquid detergent composition in which a high concentration of a nonionic surfactant can be blended with a high concentration of a detergent builder without causing phase separation. be.

Moreover, this was unexpectedly achieved by using a live sweat detergent.The products of the present invention contain from 5 to 22% by weight of at least one ethoxylated nonionic surfactant; 3 to 11% by weight of at least one alkyl polyglycoside and 20 to 5% by weight of at least one alkyl polyglycoside
