Description

  The present invention relates to a powder laundry pretreatment composition.

  In homes and nursing homes where the elderly and care recipients are present, urine odor and fecal odor attached to underwear, sleepwear, sheets, etc. are a problem. These bad odors are very different from those of ordinary households composed of healthy people. Furthermore, these bad odors are difficult to remove by ordinary washing, and even if they are washed or left behind, they cannot be removed sufficiently.

  As one countermeasure against such bad odors, 8-cyclohexadecen-1-one has a β-glucuronidase inhibitory action and continuously suppresses the production of urine odors, and odors such as skatole and indole. It is known that it exhibits an olfactory receptor antagonist action effective against substances and can suppress malodors such as fecal odor derived from these malodorous substances (see Patent Documents 1 and 2). Further, Patent Document 3 describes that a combination of two specific groups of fragrances conceals bad odors such as fecal odors without causing a strong odor or generating a new unpleasant odor.

Test example (residual amount of 8-cyclohexadecen-1-one after treatment)
Regarding the amount of 8-cyclohexadecen-1-one remaining in the treated sample cloth, it contains a case where it is treated alone with a detergent containing 8-cyclohexadecen-1-one and that containing 8-cyclohexadecen-1-one And a combination of a detergent containing 8-cyclohexadecen-1-one was compared.

<Laundry treatment method>
a. Single condition (wash only with liquid detergent for clothing containing 8-cyclohexadecen-1-one)
Cotton knitted fabric (fluorescent bleached, 10 x 10 cm, dyeing test material Tanigami Shoten Co., Ltd.) with a bath ratio of 20 in a targotometer (manufactured by Ueshima Seisakusho) containing 0.83 g / L of liquid detergent for clothing shown in Table 5 Purchased) and washed at 120 rpm for 10 minutes. Thereafter, the water was changed and rinsed at 120 rpm for 6 minutes, and then the sample cloth was transferred to a high-speed dehydrator (Somera, manufactured by Nippon General Appliances) and dehydrated at 2700 rpm for 1 minute. This was dried at room temperature for 24 hours.

b. Combination conditions (washing with powder washing pretreatment agent containing 8-cyclohexadecen-1-one + liquid detergent for clothing containing 8-cyclohexadecen-1-one)
Cotton knitted fabric (fluorescent bleached, 10 x 10 cm, purchased from Tanigami Shoten Co., Ltd.) for 30 minutes at a bath ratio of 10 in 5 g / L of the powder laundry pretreatment composition shown in Table 6 Soaked.
Thereafter, the sample cloth was transferred to a targotometer (manufactured by Ueshima Seisakusho Co., Ltd.) and washed with water at a bath ratio of 20 containing 0.83 g / L of a liquid detergent for clothing shown in Table 5 for 10 minutes at 120 rpm. Next, the water was replaced and rinsed for 6 minutes at 120 rpm, and then the sample cloth was transferred to a high-speed dehydrator (Somera, manufactured by Nippon General Appliance Co., Ltd.) and dehydrated at 2700 rpm for 1 minute. This was dried at room temperature for 24 hours.

<Analysis method>
The sample cloth after the washing treatment was extracted using 30 mL of ethanol (with Lactone C-9 added as an internal standard). The extract was concentrated with a rotary evaporator to obtain a measurement sample. A gas chromatograph mass spectrometer was used for the measurement. N = 3 samples were measured under single conditions and combined use conditions, respectively, and the average value was defined as 8-cyclohexadecen-1-one residual amount. The results are shown in Table 7.

  Here, when the case in which the total amount of 8-cyclohexadecen-1-one contained in the washing bath remains in the sample cloth is assumed to be 100%, the residual ratio is as shown in Table 8.

  Table 9 shows the residual ratio in the case of washing with the powder washing pretreatment composition alone, derived from the residual amount of (combined condition-single condition).

  Therefore, it is estimated that only 1.6% of 8-cyclohexadecen-1-one remains when treated with a clothing detergent alone, whereas 6.4% remains when treated with a powder laundry pretreatment composition alone. .
