Description

  The present invention relates to a transparent or translucent liquid softener composition and a liquid softener composition article.

It has already been known to adjust the pH of a liquid softening agent composition having a quaternary ammonium compound having an ester group as a main base to a specific range (Patent Documents 1 and 2). Moreover, the liquid softening agent composition whose appearance is transparent or translucent is already known (Patent Documents 3 to 10).
Japanese Patent Laid-Open No. 63-6168 JP-A-5-98571 JP-T-2001-515151 JP 2001-524614 A JP-T-2001-524616 JP-T-2002-505391 Japanese Patent Laid-Open No. 2004-60079 JP 2004-232163 A JP 2004-84143 A JP 2004-84144 A

  Since the liquid softener composition based on a biodegradable quaternary ammonium compound having an ester group as a main base undergoes hydrolysis of the ester group during storage, the pH as described in Patent Documents 1 and 2 Hydrolysis is suppressed by adjusting the acidity.

  In recent years, a softening agent composition having a transparent or translucent appearance has been developed from an aesthetic point of view. Patent Documents 3 to 10 include a quaternary ammonium compound having an ester group and a specific one. A technique using a solvent having LogP is disclosed. Moreover, these transparent softening agent compositions are also adjusted to acidic pH for the purpose of suppressing hydrolysis.

  On the other hand, fragrances and dyes are generally used in liquid softener compositions from the viewpoint of palatability, but under acidic conditions, the stability of the fragrances and the stability of the dyes are impaired. In particular, when applied to a transparent softener, it is preferable that a transparent plastic container is filled so that it can be visually observed that the appearance is transparent, but it contains a fragrance and a dye, and has an acidic pH. When such a container is filled with a softening agent composition, there is a serious problem that light causes significant perfume deterioration and dye fading. As a method for solving these problems, it is effective to increase the pH of the softening agent composition. In this case, however, hydrolysis of the quaternary ammonium compound having an ester group is promoted. Therefore, there is a strong demand for a technique that achieves both stability of perfume and dye and suppression of hydrolysis.

  The problem to be solved by the present invention is a liquid softener composition which suppresses hydrolysis of a quaternary ammonium compound having an ester group and does not cause deterioration of a fragrance and dye fading even when filled in a transparent plastic container. And providing a liquid softener composition article.

While stirring with a turbine-type stirring blade having three stirring blades each having a length of 2 cm (300 r / m), required amounts of the components (b) and (f) were dissolved.

  Next, the mixture (40 degreeC) which mixed the required amount (a) component and (i) component previously was added. After stirring for 5 minutes, add component (c), component (d), component (g), and component (h) sequentially, and after stirring for 5 minutes, target with 35% aqueous hydrochloric acid and 48% aqueous sodium hydroxide. The amount of ion exchange water at 60 ° C. necessary for adjusting to pH and completing the mass was added.

  Thereafter, the mixture was stirred for 10 minutes, the beaker was transferred to a water bath containing 5 ° C. water, and cooled to 25 ° C. while stirring. In addition, pH shown in Table 1 described pH after cooling (25 degreeC).

<Container>
Container 1; 100 parts by mass of polyethylene terephthalate resin (described as PET in the table) is melted, 0.1 part by mass of 2- (2H-benzotriazol-2-yl) -p-cresol, and 1.0% of titanium oxide Part by weight was added. A twin screw extruder was used for these kneading. A polyester resin composition was prepared by drying the molten resin extruded by a twin screw extruder. Using this polyester resin composition, stretch blow bottles having an average wall thickness of 0.9 mm and an internal volume of 1000 ml were formed by stretch blow molding. The light transmittance at 660 nm of this container was 30% or more.

[Evaluation of flexibility in flexible processing of clothing]
(Flexible processing method)
Five bath towels (100% cotton) were washed with a washing machine using a commercially available weakly alkaline detergent (attack from Kao Corp.) (Toshiba 2-tank washing machine VH-360S1, detergent concentration 0.0667% by mass, 30L tap water, water temperature 20 ° C, 10 minutes). Thereafter, the cleaning liquid was discharged, dehydrated for 3 minutes, poured 30 L of tap water, rinsed for 5 minutes, and dehydrated for 3 minutes after drainage. Thereafter, after 30 L of tap water was poured again, 7 ml of the liquid softener composition shown in Table 1 was added and stirred for 5 minutes. Then, it dehydrated and air-dried indoors. The flexibility evaluation of the clothing which repeated this operation 5 times was evaluated by the following method.

(Evaluation of clothing flexibility)
The odor of the processed clothing is determined by 10 panelists (10 men in their 30s) according to the following criteria, the average of 10 is taken, the average score is 0 or more and less than 1, and 1 or less and less than 1.5 Δ and 1.5 or more were judged as x.
