Storage stability was evaluated in the same manner as in Example 1. Moreover, the adsorption rate of the fragrance | flavor component was measured with the following method. The results are shown in Table 3. The components in Table 3 are the same as those used in Example 1 and the like. Moreover, the liquid softening agent composition of Examples 12-15 can provide the softness | flexibility equivalent to a commercially available liquid softening agent all.

<Measurement method of adsorption rate of perfume ingredient>
(1) Pretreatment In advance, using a commercially available weak alkaline detergent (attack made by Kao Corporation), 24 cotton towels were repeatedly washed 5 times with Hitachi fully automatic washing machine NW-6CY and dried indoors. Excess drug was removed (detergent concentration 0.0667% by weight, using 47 L of tap water, water temperature 20 ° C., washing 10 minutes, twice for rinsing).

(2) Treatment of composition to textile products
Inject 5L of tap water into National Electric Bucket N-BK2-A, dissolve the liquid softener composition to 10g / 1.0kg of clothing (preparation of treatment bath), and pre-treat with the above method. Two performed cotton towels were soaked for 5 minutes and treated.

  The adsorption rate of the fragrance is the amount by which the difference [(x) − (y)] between the fragrance component content (x) in the treatment bath before treatment and the fragrance component content (y) after treatment is adsorbed on the towel. As a percentage (percentage) to the fragrance component content (x) before treatment, that is, [(x) − (y)] / (x) × 100 is defined as the fragrance component adsorption rate. The results are shown in Table 2. In addition, content of the fragrance | flavor component in the processing liquid for a test before and behind a process was measured using the following liquid chromatography apparatus.

Liquid chromatography device: HITACHI L-6000
Column: Lichlorosphere 100 RP-18 (e) 5 μm 125 mm × 4φ
Column temperature: 40 ° C
Eluent: A mixed solution of acetonitrile / water = 7/3 (mass ratio) Flow rate: 1.0 mL / min
Detector: UV (220 nm)

* Fragrance component 1-1, fragrance component 1-2, and fragrance component 1-3 correspond to fragrance component 1.
