JP5432345B2 - Powder detergent composition for clothing and method for producing the same - Google Patents

Description

  The present invention relates to a powder detergent composition for clothing and a method for producing the same.

  There are two types of clothes washing methods: hand washing and washing machine washing. In recent years, there has been a tendency for washing machine washing to increase due to the widespread use of washing machines, but there are still many needs for hand-washing washing from the viewpoint of stain removal and economic efficiency. In addition, hand washing is often employed so that washing can be performed with as little water as possible in regions where water resources are small in the world.

  In hand-washing and washing machine washing, especially hand-washing, in addition to detergency, the richness of foaming during washing and the ease of rinsing after washing are important issues. In hand-washing laundry, foaming firmly from the start of washing (hereinafter sometimes referred to as fast foaming) leads to ease of washing, and quick foaming is required. Also, in areas where water resources are scarce, it is highly desirable to wash in which the foam disappears quickly in the rinsing process and the rinsing is completed with a small amount of water. However, when an active agent having a high quick-foaming property is used to improve the quick-foaming property, the rinsing property is deteriorated. Further, in order to improve rinsing, it is necessary to use a surfactant having good defoaming. However, when such a surfactant is used, the foamability at the time of washing is greatly impaired. Especially in the case of hand-washing, there are cases where detergent is added if foaming is not good at the time of washing, so in hand-washing washing, the balance between foaming at the time of washing and ease of rinsing after washing is an important issue. It was. Patent Document 1 discloses a cleaning composition containing a nonionic surfactant, a specific anionic surfactant, and a fatty acid having 8 to 18 carbon atoms or a salt thereof under specific conditions. It is disclosed that the detergent composition has excellent foaming properties, and the foam disappears quickly in the rinsing step, and the rinsing is completed quickly.

  On the other hand, conventionally, phosphates such as sodium tripolyphosphate have been mainly used as a builder for a cleaning agent. Sodium tripolyphosphate has excellent performance as a builder for detergents, such as chelate performance, but since it contains phosphorus, wastewater that has been washed containing it is released as it is, which is one of the eutrophication phenomena of rivers and lakes. It becomes a cause. Therefore, detergents that do not use sodium tripolyphosphate have been developed. Although the compositions of Patent Documents 2 to 4 are known as attempts to reduce the phosphate, the basic performances such as detergency, foaming, and foam removal are not satisfactory. In particular, when using high-hardness washing water, it has been difficult to achieve excellent detergency, foaming, and foam loss when the builder component is reduced.

  Patent Document 5 discloses an effective amount of an aliphatic alcohol having a melting point of 6 ° C. to 70 ° C. for improving the solubility of a detergent composition, a cleaning builder, and a granular detergent composition in an aqueous laundry solution. However, there is no mention of coexistence of foaming (rapid foaming) and foam breakage. Furthermore, Patent Document 6 discloses a highly foamable laundry composition for hand washing comprising an anionic surfactant, a specific nonionic compound, and a builder selected from betaine, fatty acid amide, amine oxide, and aliphatic alcohol. Is disclosed, but there is no mention of bubble breakage.

At that time, a nonionic surfactant (average of 6 moles of oxyethylene added to a primary alcohol having 12 carbon atoms), amorphous sodium silicate, and sodium carbonate in 1: 1: 3 (mass ratio). The mixture was used at 0.5 g / L. Thereafter, running water was rinsed with a two-tank washing machine (manufactured by HITACHI, PS-H35L'2008) using hard water having a water temperature of 20 ° C. and 89.5 mg / L in terms of calcium carbonate. When rinsing was stopped, rinsing was performed until the foam disappeared completely, and the treatment agent and the cleaning component were removed and dried by natural drying, and used as an underwear for evaluation.

<Evaluation>
(1) Evaluation of foaming property A model circular washbasin (cylindrical acrylic container having a bottom diameter (inner diameter) of 25 cm and a height of 15 cm), a water temperature of 20 ° C., 179 mg / L of hard water in terms of calcium carbonate [German hardness: 10 ° DH] [1.58 g of calcium chloride CaCl ₂ · 2H ₂ O and 1.45 g of magnesium sulfate MgSO ₄ · 6H ₂ O to 10 L by adding ion-exchanged water, Ca / Mg = 6/4 (mol Ratio)] 3L injection. Next, the powder detergent composition is added and dissolved so that the total amount of the component (A) is 750 ppm. Next, the prepared oil shown below was heated (60 ° C.), and the underwear was dripped using a spoid (φ: 2 mm) on the neck so that 1 g per 3 sheets (about 0.33 g per sheet). Pour and leave for 15 minutes in a fully immersed solution. After leaving, the neck is attached to one undergarment and the neck is washed 50 times (converted to 1 time in one reciprocation (about 1 second) while rubbing the necks together). Then, without taking out the underwear, the height of the foam in the state immersed in water is measured. In each area where the model circular wash basin is divided into 4 parts (divided into 4 sectors), the foam height from the water surface from the outside is 1 place (total 4 places) in each area using a ruler etc. Measure the height and calculate the average value. The same evaluation was performed by three persons, and the average value of these three persons was used as an evaluation standard.

  If the rapid foaming property during the washing process is not good, it is difficult to squeeze, and it is visually perceived as insufficient cleaning power, and there are cases where detergent is added to increase foaming in order to improve foaming. Therefore, the amount of detergent used per time may increase. As a result of conducting a questionnaire on foaming to Chinese women aged 25 to 39 (N = 20), 35% of women answered that if the foam height is 0.5 cm or more, 80% if it is 1.0 cm or more Responded that 90% of women were satisfied at 1.5 cm or more. From this result, the bubble height during washing is preferably 1.0 cm or more.

* Prepared oil Lauric acid 1% by mass, myristic acid 7.1% by mass, pentadecanoic acid 5.3% by mass, palmitic acid 14.2% by mass, heptadecanoic acid 1% by mass, stearic acid 3.6% by mass, oleic acid 17 0.8% by mass, 30% by mass of triolein, 5% by mass of n-hexadecyl palmitate, and 15% by mass of squalene were heated to about 60 ° C., and uniformly dissolved and mixed.

(2) Rinsability evaluation In a model circular washbasin (a cylindrical acrylic container having a bottom diameter (inner diameter) of 25 cm and a height of 15 cm), as a rinse water, a water temperature of 20 ° C., 179 mg / L of hard water (calcium carbonate equivalent) (5) prepared in the same manner as that used in the foaming property evaluation) is injected, and three underwears squeezed in the foaming property evaluation are introduced. After rinsing the underwear in water, lift the loose underwear one by one by holding the Eli part up from the bath (lift from the bath to the height of about 5 cm above the basin until the entire clothing comes off), then Return to the bath again. After rinsing by such up-and-down movement 10 times for each undergarment, the water content of the undergarment is squeezed 10 cm above the basin so that the moisture content of the undergarment is about 100 to 140% of the undergarment. The state of the rinse water immediately after rinsing and dehydration was observed, and points were assigned according to the following criteria to evaluate rinsing properties.
Point 6: Foam with a height of 1 cm or more remains on the entire liquid surface 5: Foam remains on the entire liquid surface (less than 1 cm)
4: Bubbles (less than 1 cm) remain on about 1/2 of the liquid level 3: Bubbles (less than 1 cm) remain on about 1/4 of the liquid level 2: Fine bubbles remain on the liquid level 1 : No bubbles remain on the liquid surface

If the foaming during the rinsing process is not good, the number of times of rinsing is increased until the foam is broken. As a result, a large amount of water is consumed. From such a viewpoint, it is preferable that there are few bubbles at the time of a rinse, 3 points or less are preferable at said point, 2 points or less are more preferable, and 1 point is still more preferable.
