Description

MANUFACTURING METHOD OF LIQUID LAUNDRY DETERGENT WITH
NANO-SIZED SILVER COLLOID
Technical Field
The present invention relates to a liquid type laundry detergent containing nano-sized silver particles. By adding nano-sized silver particles prepared in the colloidal state in various solvents such as an aqueous or non-aqueous solution to a liquid type laundry detergent, it is possible to give properties of silver such as antibiotic effect, antifungal effect, deodorization, emission of far infrared rays and antistatic effect to the laundry detergent. The silver particles not only show the above- listed properties during cleaning but also adhere onto the laundry, thereby providing the above-mentioned properties to the laundry even after cleaning.
Background Art As the standard of living of people is improved and causes of various diseases are closely examined, understanding of the sanitation becomes increased. In the fields of detergents for laundry, products with antibiotic effect are put on the market. Since most of bleaching agents have antibiotic effect, it has been attempted to add a bleaching agent to a detergent from former days. However, detergents with a bleaching agent added thereto may cause discoloration in the laundry such as colored fabric. When an antibiotic agent of a surfactant type is used in a detergent, if the laundry is dried in a shade place with poor ventilation, the laundry generates offensive odor after drying and gets moldy after long-term storage in a damp place, since the antibiotic agent has a low residual rate on the laundry. Also, there is a product using a photocatalyst in a detergent to. provide properties of the photocat'alyst . However, it has problem in that blue spots are formed when the laundry is soaked in the detergent for a long period of time. Therefore, according to the present ' invention, silver which is known for its antibiotic effect and other functions is added to a detergent. Recently, various materials are used to provide a functionality to a detergent. As an instant, there are a product using chitosan or a product using orange extract in order to supplement the skin protecting function of the detergent for dish washing. As examples of products using silver, there are antibiotic nursing bottles, cosmetic facial cleansing soap and silver ion emitting washing machine. However, there has never been instance applying silver to detergents for laundry.
Disclosure of Invention
Thus, it is an object of the present invention to solve the problems found in the laundry upon cleaning using the conventional detergent as described above by adding nano-sized silver particles to a detergent and to give intrinsic functions of silver such as antibiotic effect, deodorization, antifungal effect, emission of far infrarec rays and antistatic effect to the laundry by attachment of nano-sized silver particles to the laundry upon cleaning.
Best Mode for Carrying Out the Invention
Now, the present invention will be explained in detail . The present invention is directed to a liquid type detergent composition ' prepared by adding silver particles to a liquid type detergent in a predetermined ratio, followed by stirring. The method for preparing silver particles which can be used in the present invention is not particularly limited. They can be in the colloidal state or in the well-dispersed powder state. However, upon addition to a liquid type detergent, they are preferably in the colloidal state prepared from an aqueous or non-aqueous system. In order for the silver particles in the colloidal state to be applied in a detergent, chemical stability between the detergent and the silver sol is very important. The silver colloid which has been prepared without using a dispersing agent or stabilizer does not cause any problem when it is applied in a liquid type detergent. Considering the reactivity of various substances added to the silver sol with components of the detergent, the silver colloid should be one prepared using a non-reactive additive. For example, when a silver sol prepared using a large amount of a cationic surfactant is added to a detergent comprising an anionic surfactant, a sold precipitations may be formed by the reaction of the cationic surfactant of the silver sol and the anionic surfactant of the detergent. In a contrary situation, the same result may be observed. Also, though the detergent shows stability while not used, abnormal products may be formed by the reaction between the components of the detergent and the substances added in the preparation of the silver sol upon washing. Therefore, the silver sol to be added to the detergent should be selected by considering the reactivity with the components of the detergent upon washing or not washing.
The concentration of the silver sol does not matter as long as the silver sol may maintain the colloidal state without precipitation and coagulation. However, since the prepared silver may cause change in the detergent according to the concentration of silver when it is added to the detergent, it is important to control the concentration of silver. When the content of silver added to the detergent is great, the production cost of the detergent is increased and precipitation and color change may occur in the detergent, even when the silver is used in the well- dispersed colloidal state. Also, silver particles may cohere to form coarse secondary particles. In this case, the secondary particles adhere onto the laundry to form micro spots, causing color change in the laundry. Therefore, the concentration of silver added to the detergent is 1000 ppm or less, preferably 100 ppm or less, more preferably 30 ppm or less.
The silver particles added to the detergent are preferably nano-sized. Generally, the nano-size is 100 nm or less. When the silver particles are too big, precipitation may occur and adhere onto the- laundry to form spots and cause abnormal color change. Therefore, the silver particles used in the present invention has a size of 100 nm or less, preferably 30 nm or less, more preferably 10 nm or less.
Now, the present invention will be described in further detail using the following Examples and Comparative Example. Example 1
A silver sol having a particle size of 10 nm or less, which had been prepared in an aqueous solution, was added to a liquid type laundry detergent mainly comprising an anionic surfactant and a non-ionic surfactant. Here, the silver sol has a concentration of 100,000 ppm. 1 g of the silver sol was added to 39 g of the liquid detergent while stirring. The silver sol was diluted to a ratio of silver, of 500 ppm, 100 ppm, 30 ppm and 10 ppm, proportional to the total weight of the detergent. The stirring was continued until the silver was completely dispersed in the solution, sealed and left to stand in a general environment of home kitchens . After 30 days, the conditions of each detergent was examined and subjected to a laundry test. Particularly, a white cloth was stained with various contaminants such as coffee, edible oils, dusts and the like and washed with the detergents to evaluate the washing effect. Also, a white cloth without stains was washed with the detergents to examine wether the detergents cause any abnormal condition to the cloth. 10 panels witnessed the evaluation of the examination. As a result, the detergent with nano-sized silver particles added showed effects similar to the same liquid type detergent but without containing nano-sized silver particles and a powder type detergent, without abnormal spots. In order to examine generation of offensive odor after drying the laundry, the laundry was dried in a shade place with poor ventilation. 10 panels witnessed the evaluation and judged that the laundry has less offensive odor as compared to the detergent without i silver contained therein.
Example 2
A silver sol having a particle size of 10 nm or less and a concentration of 10,000 ppm, which had been prepared in a non-aqueous solution (ethylene glycol) , was added to a liquid type laundry detergent mainly comprising an anionic surfactant and a non-ionic surfactant. 1 g of the silver sol was added to 39 g of the liquid detergent while stirring. The silver sol was diluted to a ratio of silver, of 200 ppm, 100 ppm, 30 ppm and 10 ppm, proportional to the total weight of the detergent. The washing effect and other abnormal conditions were evaluated following the same procedures as described in Example 1. Consequently, results similar to those of Example 1 were obtained. Comparative Example 1
A silver sol which had been prepared in an aqueous solution was added to a liquid type laundry detergent mainly comprising an anionic surfactant and a non-ionic surfactant. Here, the silver sol has a particle size of 30 nm or less and a concentration of 100,000 ppm. 1 g of the silver sol was added to 39 g of the liquid detergent while stirring. The silver sol was added in a mixing ratio of silver to the total weight of the detergent of 2,500 ppm. • After achieving complete dispersion of silver particles, the mixture was left to stand in a general environment of home kitchens. After addition of silver, the detergent changed its color from green to blue. After 15 days, a part of silver particles was settled down to the bottom. Also, after 30 days or more, there was perceived a difference in color between the upper part and the lower par of the detergent. The laundry test was performed under same conditions and as a result, spots were observed on the laundry.
.Comparative Example 2
Washing and drying were performed under same conditions, except using a liquid type laundry detergent without silver and a powder type laundry detergent. As a result, when the laundry which had been dried in a shade place with poor ventilation had more offensive odor, as compared to the laundry which had been washed with the detergent with nano-sized silver particles .
