[Detailed description of the invention]

TECHNICAL FIELD AND BACKGROUND This invention relates to aqueous high-foaming liquid detergent compositions containing specific amounts of specific types of surfactants that are particularly useful for cleaning hard surfaces of tableware, kitchen utensils, and other articles. The composition of the present invention allows the rinsing water to be more completely removed from surfaces such as glass, ceramics, and metals, thereby eliminating spot formation and film formation, especially when cleaning cooking utensils that involves only draining without towel drying. decreases. Users evaluate the performance of detergent compositions used to clean glass tops, dishes, and other items that normally have bright surfaces based on shine and the presence or absence of films, streaks, and spots. Liquid kitchen detergent compositions currently available on the market are designed to remove stains from glasses, dishes, and other tableware and kitchen utensils. Common detergent solutions and re-sedimented dirt are removed from the item by rinsing and, if the item is still wet, toweling. If you do not rinse and towel dry, dirt may dry on the surface of the item being cleaned, leaving behind a film, streaks, or spots. Even if such items are perfectly clean, rinsing them in water containing dissolved salts, such as hard water, may leave spots or streaks on the cleaned surface after the water evaporates. It is undesirable from the viewpoint of convenience and hygiene to immediately towel clean items such as glass tops and dishes after washing and rinsing them. Accordingly, it is common practice to drain and air dry washed or washed or rinsed items. As a result, the cleaning efficiency of the detergent used, which the housewife may actually rate after washing or rinsing, is reduced by the build-up of re-sedimented dirt, dry detergent and hard water residue. In U.S. Pat. No. 3,963,649 by Spadini et al.
A liquid detergent composition containing a nonionic surfactant and a water-soluble gel-forming gelatin is disclosed. The composition is said to minimize film, streak and spot formation on tableware and kitchen utensils. The essential nonionic surfactant is the tertiary
amines or phosphine oxides, amides or ethylene oxide condensation products, as well as organic hydrophobic compounds. US Pat. No. 3,983,079 by Spadini et al. discloses a kitchen detergent composition that is said to have excellent rinsing water removal properties. The composition contains a water-soluble quaternary ammonium compound, a nonionic surfactant including both ethylene oxide and propylene oxide, and a sultaine or betaine zwitterionic surfactant. U.S. Pat. No. 4,144,201 to Winterbotham et al. discloses liquid kitchen detergent compositions containing soluble casein to improve drainage and softness. Belgian Patent No. 845184 describes the use of a specific type of surfactant to provide rapid drainage and a bright surface.
Kitchen liquid and granular detergent compositions containing one or more types have been disclosed. It is an object of the present invention to provide a liquid detergent composition and cleaning method that drains rinse water quickly and relatively completely, thereby reducing spots and films on surfaces such as glass, ceramics and metals. There continues to be a need for compositions and methods for cleaning cleaned and dried kitchen utensils and articles to improve their appearance. If the use of such compositions and methods is intended for conventional soil removal tasks, the surface activity, foaming, and softness of a good dishwashing detergent composition and the aforementioned spot and film removal properties should be combined. Compatible mixtures of substances such as those given are always required.

On average, about 18 to 50 moles of ethylene oxide are ethoxylated per mole of alcohol. Foam Stabilizing Nonionic Surfactants The compositions of the present invention contain about 2-8% of foam stabilizing nonionic surfactants or mixtures thereof, which foam stabilizers include the essential drainage-enhancing nonionic surfactants. It has a different chemical structure and function than ionic surfactants.

R ₃ is methyl or ethyl. ) The preferable foaming property of the composition of the present invention is such that it can demonstrate to the user of the composition its cleaning power as a cleaning solution. The dirt encountered in dishwashing acts as a suds suppressor, and the presence or absence of suds on the surface of the washing liquid provides a convenient guide to the use of the composition. In the compositions of the present invention, a mixture of anionic surfactants and foam-stabilizing nonionic surfactants is used, which provides the composition with high foaming properties, foam stability in the presence of food soils, and This is to provide the ability to accurately indicate the appropriate amount of composition to use in the presence of soil. Additionally, but most importantly, two other important surfactants of the present invention (not foam stabilizing nonionic surfactants as defined by Tashiko):

Amphoteric surfactants can be broadly described as derivatives of aliphatic amines having long chains of about 8 to 18 carbon atoms and water-solubilizing anionic groups such as carboxy, sulfo or sulfate. Examples of compounds that fall within this definition are sodium-3-dodecylaminopropanesulfonate and dodecyl diethylammonium hexanoate. Zwitterionic surfactants that can be used in the compositions of the present invention include those in which the aliphatic groups are linear or branched, one of the aliphatic substituents has about 8 to 18 carbon atoms, and one of the aliphatic substituents has a water solubilizing anion. It is broadly described as the internal neutralization induction of aliphatic quaternary ammonium and phosphonium and tertiary sulfonium compounds having ionic groups such as carboxy, sulfo, sulfato, phosphato, or phosphono. Cationic surfactants, such as quaternary ammonium compounds, may optionally be used when utilizing the present invention, provided that the surfactants are compatible with the other surfactants in the composition in question.
