- Particle-containing liquid g Fine Seal A, average particle size 250 nm, manufactured by Tokuyama Corporation (purity 95% by mass)
- the liquid cleaning composition for textile products is used in Examples 1 and 2, and the liquid composition for reducing allergens is used in Example 3.
- the compounding amounts of the particle-containing liquids a and c were such that the concentration of the water-insoluble particles containing the synthetic inorganic substance as a main component contained in each of the compounds had the composition shown in the table.
- compositions obtained in Examples 1 to 3 were all colorless and transparent.
- Example 2 For each of the obtained compositions, the allergic symptoms reducing effect and The dispersion stability was evaluated.
- 20 mL of the obtained liquid cleaning composition for textiles was added to 30 L of the washing liquid to wash the cloth to which pollen had adhered, and the allergic solution was washed using the washed cloth.
- the symptom-reducing effect was evaluated.
- the laundry did not cause any discoloration of the fabric.
- Example 3 0.5 ml of the obtained liquid composition for reducing allergen was sprayed uniformly on the cloth surface to which pollen had adhered, and the effect of allergic symptom reduction was evaluated using the cloth after the spray treatment. This spraying did not cause discoloration of the fabric.
- Table 2 The evaluation results are shown in Table 2 below.
- a body composition was prepared.
- the amount of the particle-containing liquid c was adjusted such that the concentration of the water-insoluble particles containing the synthetic inorganic substance as a main component contained therein was the composition shown in the table.
- the fiber treatment liquid composition obtained in Example 4 was colorless and transparent.
- the effect which reduces an allergen can be obtained stably, the discoloration of the to-be-processed object, such as a textile product, is small, and the dispersion stability at the time of liquid product combination is excellent,
- An allergen-reducing agent suitable for blending and using, a composition containing the allergen-reducing agent, and an allergen-reducing method using these are obtained.
