Description

Rinsing detergent composition for kitchen {SPEEDY RINSING DISHWASHING DETERGENTS COMPOSITIONS}

[Industrial use]

The present invention relates to a dish detergent composition having excellent rinsing properties, and more particularly to a dish detergent composition of liquid or gel type suitable for use in a manual dishwashing operation.

[Prior art]

With the development of scientific civilization and the development of surfactant industry in the modern times, the development of dishwashing detergent for kitchen is becoming the core.

In general, highly stained dishes may present particular problems during manual dishwashing operations. That is, when washing stained dishes such as dishes, household pot pans and pottery by hand, a relatively large amount of food stains and residues may still remain in the dishes and stain. The food stain residue may be due to the nature of the surface of the dishes to be washed. In addition, food stain residues that do not stick together may be due to the type of cooking operation performed on the stained tableware.

Therefore, when washing the above highly stained dishes, they are often used with a very high concentration of detergent, or directly using a highly concentrated liquid or gel product in its pure type without dilution. At this time, the pH characteristics of the composition for dishwashing may be determined by solubilizing food stains such as oil stains. In addition, since contamination and detergent generally remain in dishes, it is a factor of dissatisfaction with detergent hazards and performance after washing, so it is important to wipe the stains and stains well, but the condition of the dishes after rinsing with water is also important.

In addition, in addition to being useful for dish washing, the LDL or gel composition preferably has properties that enhance the aesthetic or consumer awareness of the effect of manual dishwashing. The cleaning performance in the dish washing depends not only on the preparation of the foam which lasts well in the dish washing process but also on the rinsing water required to generate a suitable amount of foam in the initial washing water and to remove the foam. Therefore, liquid or gel detergents for manual dishwashing should use materials that enhance the cleaning performance of the cleaning solution.

Liquid or gel detergent compositions useful for such manual dish washing are well known in the art. In general, liquid or gel dishwashing detergent products are generally formulated to provide a variety of performance and aesthetic properties and properties, and during dishwashing, the formulated products are prepared and used in aqueous solution. In addition, the liquid or gel dishwashing detergent product should be formulated according to the type and amount of surfactant and other cleaning aids effective to solubilize and remove food stains, especially oily stains, from the dishes to be washed.

Conventionally, the dishwashing detergent for kitchen is a liquid dishwashing detergent containing 10 to 15% by weight of an active ingredient is widely used. In addition, the kitchen detergent is a liquid form of the mainstream in the general form, the liquid type is a general-purpose form has been used since the first development of the kitchen detergent, which has the advantage of easy handling and easy to use. However, in the case of the detergent, the content of the active ingredient is limited to about 10 to 50% by weight, and if it is 50% by weight or more, it is difficult to solubilize the surfactant and relatively deteriorate the physical properties of the detergent itself or maintain a liquid form. Becomes difficult.

As such, research has been continued to formulate a liquid or gel for manual dish washing having excellent washing function and additional function of a highly concentrated product or a diluted aqueous solution for use in dish washing.

Test Example

(Dishwashing and Rinsing Force Experiment)

The KS M 2716 method and the method of washing and rinsing contaminated tableware were used. 3 g of the liquid detergent composition of Examples 1 to 8 were buried in a sponge and contacted with contaminated tableware. At this time, the actual amount of the liquid detergent composition used is based on the judgment of the user, such as the specific product formulation of the composition, including the concentration of the active ingredient in the composition, the number of contaminated dishes to be washed and the degree of contamination on the dishes, and the like. It depends on the factors. When 3 g of detergent was applied, it was mixed with 1000 g of water (more typically 2000 g) of the sink. A cloth, sponge or similar product may be immersed into the mixture of detergent composition and water prior to contacting the tableware surface, and is usually in contact with the tableware surface for about 10 seconds although the actual cleaning time may vary depending on the respective application and user. At this time, the process involved rubbing the surface of the dishes at the same time.

After foaming and rubbing the surface of the tableware directly, a certain amount of rinsing water was used to measure the number of rinses and the rinsing time for the rinsing immediately after washing, and the rinsing time and the rinsing water were foamed by the visual indicator. The extinction end time was measured and carried out.

As described above, according to the present invention, it is possible to effectively remove food stains from dirty dishes when performing manual dishwashing operations, and to provide an excellent dish detergent composition for washing after washing.
