Examples of these surfactants may be found in NcCutcheon, Detergents and Emulsifi- ers 1993, incorporated herein by reference. Examples of nonionic surfactants will include commonly utilized nonionic surfactants which are either linear or branched and have an HLB of from about 6 to 18, preferably from about 10 to 14. Examples of such non ⁇ ionic detergents are alkylphenol oxyalkylates (preferably oxye- thylates) and alcohol oxyethylates.

- the laundry detergent formulation will also contain one or more electrolytes.
- Electrolytes defined herein are any ionic water- soluble material. The presence of the electrolyte is often re ⁇ quired to bring about the structuring of the detergent active ma ⁇ terial, although lamellar dispersions are reported to be formed with detergent active material alone in the absence of a suitable electrolyte. Electrolytes typically comprise from about 1 to 60% by weight, and more preferably about 25 to 35% of a laundry de ⁇ tergent formulation.
- Suitable electrolytes include compounds capable of providing sufficient ionic strength to the aqueous detergent com- position. These compounds would include alkali metal salts of citric acid, alkali metal carbonates, and alkali metal hydrox ⁇ ides. Of these, sodium citrate, sodium carbonate and sodium hy ⁇ droxide are preferred. Potassium salts can also be incorporated to promote better solubility, other examples of suitable electro- lytes will include the phosphate salts such as sodium or potas ⁇ sium tripolyphosphate, and alkali metal silicates.
- the electrolyte utilized will also serve as the builder for enhancing detergency.
- the builder material sequesters the free calcium or magnesium ions in water and promote better detergency. Additional benefits provided by the builder are in ⁇ creased alkalinity and soil suspending properties.
- the most commonly used non-phosphate builders are the alkali metal ci- trates, carbonates, bicarbonates and silicates. All of these compounds are water—soluble.
- Water-insoluble builders which re ⁇ move hardness ions from water by an ion-exchange mechanism are the crystalline or amorphous aluminosilicates referred to as zeo ⁇ lites.
