In the cleaning composition of the present invention, the above 3
The total amount of the ingredients can normally be in the range of 10 to 40 wt%. The detergent composition of the present invention may contain conventional detergent additives that have been mixed in conventional detergent compositions in conventional amounts. And these detergent additives include inorganic builders such as silicates, aluminosilicates, tripolyphosphates, pyrophosphates, orthophosphates, carbonates, sulfates, polymaleates, copolymers of maleic acid and olefins, etc. organic builders such as citrate, oxydiacetate, oxydisuccinate, nitrilotriacetate, organic chelating agents such as EDTA, anti-caking agents, fluorescent brighteners, soaps, enzymes and fragrances, etc. . Next, the structure and effects of the present invention will be explained in more detail by showing examples. In each example, various cleaning compositions were prepared in which the type and/or amount of surfactant used as an active ingredient was varied, and the foaming power and cleaning power of each cleaning composition was examined. . The foaming power and cleaning power were evaluated as follows. Foaming power: Using a washing machine and 3゜DH water under the washing conditions of bath volume 30, bath ratio 1:30, detergent concentration 0.133%, and temperature 25℃, the skin shirt with organic dirt was washed. 10
After washing for minutes, spread the foam evenly over the entire liquid surface and
The foam height was measured at several locations, and the foaming power was evaluated based on the average foam height. Cleaning power: USTesting's Terg-O- is used as a cleaning device.
Using a Tomoter, add 10 artificially soiled cloths and 3 Sebum cloths, then add a clean stockinette cloth, adjust the bath ratio to 30 times, and run at 120 rpm for 10 minutes.
Wash at °C. Use 90 ml of a cleaning solution with a detergent concentration of 0.133%, and rinse with 900 ml of water for 3 minutes. The water used was 3°DH. The detergency was calculated using the formula below and expressed as the average value of 10 artificially soiled cloths. Cleaning power (%) = (K/S of dirty cloth - K/S of washed cloth) / (K/S of dirty cloth - K/S of clean cloth) x 100 K/S = (1 - R/100) ² /2R/100...[Kubelka-Munk equation] R is the reflectance (%) measured by a Carl Zeiss ELREPHO reflectance meter. Example 1 Sodium salt of α-sulfopam fatty acid methyl was used as the a component, C ₁₄ to C ₁₈ α-olefin sodium sulfonate was used as the b component, and C ₁₀ to _{C 14} linear alkylbenzenesulfonate sodium was used as the c component. Detergent compositions having the following compositions differing only in the blending ratio of these three components were prepared, and the foaming power and detergent power of each composition was evaluated. The results are shown in Table-1. Composition Total of 3 components a, b, c 20wt% Zeolite 20wt% Sodium silicate 10wt% Soda carbonate 10wt% Sodium sulfate and water Balance
