Description

  The present invention relates to a liquid cleaning composition for clothing.

In recent years, consumers have demanded that liquid detergent compositions for clothing not only impair the cleaning performance but also the residual scent performance.
Patent Document 1 contains an anionic surfactant, an amine compound having a specific structure, a nonionic surfactant, and a fragrance, and has excellent cleaning performance and anti-recontamination performance against solid particle dirt, and good flexibility. A liquid detergent composition for clothing that has good properties, has good storage stability, and can be highly blended with a fragrance composition is disclosed.

  On the other hand, attempts have been made to microencapsulate a fragrance composition for the purpose of sustaining fragrance and remaining fragrance. A microcapsule of a fragrance composition (hereinafter sometimes referred to as a fragrance microcapsule) is a particulate material in which a fragrance of a core material is wrapped with a wall material, and its role is to protect the fragrance of the core material and physically When a strong force is applied, the capsule wall breaks and releases the fragrance of the core material.

Patent Document 2 describes a fragrance microcapsule containing a fragrance composition having a flash point in the range of 50 to 130 ° C. as a core substance.
Patent Document 3 describes a fragrance microcapsule containing a volatile component such as a highly volatile fragrance and an additive having a higher melting point and compatibility.

The model sebum artificial contamination liquid was attached to the cloth by printing the artificial contamination liquid on the cloth using a gravure roll coater. The process of making the model sebum artificially contaminated cloth by attaching the model sebum artificially contaminated liquid to the cloth is carried out at a gravure roll cell capacity of 58 cm ³ / m ² , a coating speed of 1.0 m / min, a drying temperature of 100 ° C., and a drying time of 1 min. It was. The cloth used was cotton 2003 (manufactured by Tanigami Shoten).

* Composition of model sebum artificial contamination liquid: 0.4% by mass of lauric acid, 3.1% by mass of myristic acid, 2.3% by mass of pentadecanoic acid, 6.2% by mass of palmitic acid, 0.4% by mass of heptadecanoic acid, stearin 1.6% by mass of acid, 7.8% by mass of oleic acid, 13.0% by mass of triolein, 2.2% by mass of n-hexadecyl palmitate, 6.5% by mass of squalene, 1.9% by mass of egg white lecithin liquid crystal , Kanuma red soil 8.1% by mass, carbon black 0.01% by mass, water balance (total 100% by mass)

-Preparation of evaluation test cloth for residual scent property The liquid cleaning composition for clothing described in Table 1 using 10 test test cloths (6 cm x 6 cm) produced as described above, using a targotometer (Ueshima, MS-8212) For 10 minutes at 85 rpm. The washing conditions were a liquid detergent composition concentration for clothing of 0.1% by mass, a water temperature of 20 ° C., and a bath ratio of 15 (adjusted with a cloth obtained by cutting cotton 2003 (manufactured by Tanigami Shoten) into 6 cm × 6 cm). After washing, it was rinsed with tap water (20 ° C.) for 3 minutes at a bath ratio of 15 and squeezed by hand until dehydrated to 90% by mass relative to the mass of the evaluation test cloth before washing. Subsequently, after leaving it in a thermostatic chamber at 23 ° C. and 65% RH for 12 hours, it was further stored in a thermostatic chamber at 30 ° C. and 45% RH for 12 hours, thereby obtaining 10 sheets of evaluation test cloths for residual fragrance properties.

-Evaluation method of after scent property Ten cloths obtained with the evaluation test cloth of after scent property were piled up. 5 panelists skilled in fragrance evaluation (2 men and 3 women), respectively, using the test cloth of Comparative Product 2 shown in Table 1 as a reference, the strength of the scent of the test product of the present invention or other comparative products Was evaluated according to the following criteria. The average score of 5 people was calculated. A score of +0.5 was assigned if the panelist was rated between 0 and +1. A rating of +1.5 was assigned if it was rated between +1 and +2. An average score of 0.6 or more is acceptable and a higher numerical value is preferable.

+2: The strength of the fragrance from the evaluation test cloth feels stronger than the strength of the fragrance from the residual scent evaluation test cloth of Comparative Product 1.
+1: Although the strength of the fragrance from the evaluation test cloth feels stronger than the strength of the scent from the evaluation test cloth of the comparative product 1, it is closer to the strength of the comparative product 1.
0: The intensity of the fragrance scented from the evaluation test cloth and the intensity of the fragrance scented from the evaluation test cloth of the remaining scent property of Comparative Product 1 feel almost the same.

<Evaluation method of incense tone change>
5 test cloths randomly extracted from 10 test cloths obtained by the same method as the above-mentioned “Preparation of test cloth for evaluation of residual fragrance” are wrapped in aluminum foil and stored in a constant temperature room at 5 ° C. did. This test cloth was designated as test cloth (1). The remaining five test cloths were wrapped in aluminum foil and stored in a temperature-controlled room at 30 ° C. and 45% RH. This test cloth was designated as test cloth (2). Twelve hours after the start of storage, take out from each temperature-controlled room and leave it in a temperature-controlled room at 23 ° C. and 65% RH for 1 hour, and use test cloth (1) and test cloth (2). The following criteria were evaluated by 5 panelists (2 men and 3 women). A score of +0.5 was assigned if the panelist was rated between 0 and +1. A rating of +1.5 was assigned if it was rated between +1 and +2. The average score of 5 panelists was calculated. An average score of 0.8 or more is acceptable and a higher numerical value is preferable.

+2: The scent from the test cloth (2) is slightly different from the scent from the test cloth (1), but is almost the same as the scent from the test cloth (1).
+1: The scented tone from the test cloth (2) is slightly different from the scented tone from the test cloth (1), but close to the scented tone from the test cloth (1).
0: The scent tone from the test cloth (2) is clearly different from the scent tone from the test cloth (1).

The inventive products 1 to 12 have an evaluation score of residual fragrance obtained by the above method of 0.6 or more, and an evaluation score of change in fragrance is 0.8 or more, there is little change in fragrance, and fragrance strength It can be seen that this is a liquid detergent composition for clothing that lasts.
On the other hand, Comparative products 1 to 3 had a residual fragrance evaluation score of less than 0.6 and / or a fragrance change evaluation score of less than 0.8.
In the inventive products 1 to 4, the ranking of the evaluation point of the fragrance change of the fragrance derived from the perfume microcapsule is the best in the inventive product 3, then the inventive product 2, then the inventive product 1, and then the inventive product 4 It was in order. In addition, as for the persistence of the scent, the products 3 and 4 of the present invention were the best, followed by the product 2 of the present invention and then the product 1 of the present invention.
When comparing the present product 2, the present product 5, the present product 6 and the present product 12, the sustainability of the fragrance is the same as that of the present products 2 and 6, and then the present product 5 is good. Next, the product 12 of the present invention was good.
Comparing the product 3 of the present invention with the product 7 of the present invention, the evaluation points for suppression of scent modulation are comparable, but the sustainability of the scent is high in the product 3 of the present invention.
When the product 2 of the present invention is compared with the product 8 of the present invention, the effect of suppressing the scent modulation is higher in the product 8 of the present invention, and the sustainability of the scent is higher in the product 2 of the present invention.
