Definitions
- This invention relates to built liquid detergent compositions for laundry and general purpose applications which exhibit stability against phase separation.
- Built liquid detergent compositions are popular with consumers because they are easy to store, dispense and measure and do not cake as some granular detergent products are apt to do when stored for lengthy periods of time or become damp.
- a major disadvantage of built liquid detergent compositions has been their cost in comparison to the granular products. The cost of built liquid detergents is exacerbated because of the difficulties encountered in preparing homogeneous built liquid detergent compositions.
- the current commercially available built liquid detergent compositions typically contain one or more synthetic detergents and an inorganic builder, such as potassium polyphosphate, in an aqueous medium.
- an inorganic builder such as potassium polyphosphate
- One major problem encountered in formulating built liquid detergent compositions is the difficulty of including in a concentrated solution sufficient detergent and builder to provide the performance expected of a product intended for washing soiled clothing and other household chores.
- Attempts to combine the detergents and builders at effective levels in a homogeneous liquid system have resulted in the development of complicated formulae with large numbers of ingredients, including inactive cleaning ingredients such as hydrotropes, polymeric stabilizers and thickeners in these formulations.
- These inactive cleaning ingredients contribute little, if any, to the performance of the liquid detergent and, in fact, are sometimes deleterious to cleaning performance. They do increase the cost of the formulation and their use is justified only if it results in higher concentrations of detergent and builder in the solution.
- a liquid built laundry detergent composition in which a high percentage of a nonionic surfactant can be incorporated with a high percentage of detergent builder without phase separation. Further, this is unexpectedly accomplished with a material which is an active cleaning agent.
- a liquid detergent composition comprises from 5 to 22 percent by weight of at least one ethoxylated nonionic surfactant, from 3 to 11 percent by weight of at least one alkyl polyglycoside and from 20 to 50 weight percent of at least one detergent builder, and soft water.

- Stability evaluations were made by storing containers of the detergent compositions and evaluating the appearance of the compositions over time. Compositions which had phase separated, that is, formed distinct layers, over the indicated test periods, were considered to be failures and thus unacceptable. The failures are reported as "F”. The formulations which over the test period had not phase separated but exhibited some loss in homogeneity of the emulsion, e.g., creaming, were reported by the symbol "S”. These formulations while not optimal, are still satisfactory for use. Formulations which exhibited little, if any, change over the test period were reported by the symbol "P".
