Benefits of technology

[0007]The present invention also provides a method for facilitating adsorption of the component (b1) on a textile product, including contacting the composition with the textile product in water as a medium.

Problems solved by technology

These materials insufficiently release aromas and often have heavy aromas, and thus determine residual aroma tones.
However, these hydrophilic materials have poor adsorption on textile, and thus provide weak aromas to a treated textile product with less long lasting odor.

synthesis example 1

Synthesis of octylsilicic Acid tris(2-phenylethyl)ester [tris(2-phenylethyloxy)octylsilane]

[0095]In a 300 mL four-neck flask, under a nitrogen flow, 83.01 g of octyltriethoxysilane (0.30 mol), 127.76 g of phenylethyl alcohol (0.83 mol), and 0.857 mL of a solution of 2.8% sodium methoxide in methanol were stirred for 2.5 hours at 110 to 115° C., while distilling ethanol off. After 2.5 hours, the inner pressure of the reaction vessel was gradually reduced to 8 kPa. The mixture was stirred for additional 3 hours at 110 to 119° C. with distilling ethanol off. After 3 hours, the mixture was cooled and the reduced pressure was released. The mixture was filtered to give 173.61 g of yellow oil containing octylsilicic acid tris(2-phenylethyl) ester.

synthesis example 2

Synthesis of silicic Acid tetrakis(cis-3-hexenyl)ester [tetrakis(cis-3-hexenyloxy)silane]

[0096]In a 200 mL four-neck flask, under a nitrogen flow, 35.45 g of tetraethoxysilane (0.17 mol), 64.74 g of cis-3-hexenol (0.65 mol), and 1.34 mL of a solution of 2.8% sodium methoxide in methanol were stirred for about 2 hours at 118 to 120° C. with distilling ethanol off. After 2 hours, the inner pressure of the reaction vessel was gradually reduced to 8 kPa. The mixture was stirred for additional 3 hours at 112 to 119° C. with distilling ethanol off. After 3 hours, the mixture was cooled and the reduced pressure was released. The mixture was filtered to give 66.17 g of light brown oil containing tetrakis(cis-3-hexenyloxy)silane.

synthesis example 3

Synthesis of poly(4-methoxyphenylmethoxy)siloxane

[0097]In a 100 mL four-neck flask, under a nitrogen flow, 72.96 g of tetraethoxysilane, 0.24 g of potassium hydroxide, and 0.4 mL of ion-exchanged water were reacted for about 37 hours at 120 to 125° C. and 33 kPa to 101 kPa (ambient pressure). During the reaction, 0.4 mL of ion-exchanged water was further added. The reaction was continued for additional 2 hours at 33 kPa. The mixture was cooled and filtered to produce 67.29 g of ethoxysilane condensate as a light yellow liquid.

[0098]Then, in a 100 mL four-neck flask, 25.00 g of the tetraethoxysilane condensate obtained above, 56.39 g of 4-methoxyphenylmethanol, and 0.17 g of a 4.8% aqueous solution of sodium hydroxide were stirred for 2 hours at 95 to 119° C. with distilling ethanol off. After 2 hours, the inner pressure of the reaction vessel was gradually reduced to 8 kPa. The mixture was stirred for additional 3 hours at 116 to 119° C. with distilling ethanol off. After 3 hours, t...

Abstract

The present invention provides the textile treatment composition containing (a) the compound represented by the formula (1) and (b1) the fragrance having a logPow value not less than 3.0 and not more than 5.0 at a mass ratio of (a) / (b1)=98 / 2 to 20 / 80, and the method for facilitating adsorption of the component (b1) on a textile product by contacting the textile treatment composition with the textile product in water as a medium:(wherein, X represents —OH, —R1 (R1 represents an aliphatic hydrocarbon group having total 1 to 22 carbon atoms that may be substituted with a phenyl, hydroxy, or alkoxy group) or —OR2 (R2 represents a hydrocarbon group having 6 to 22 carbon atoms); Y represents X or —OSi (X) 3; and n is an average number from 0 to 15; a plurality of X and a plurality of Y may be independently same or different, with a proviso that the compound has at least one —OR2 in a molecule.)

Description

FIELD OF THE INVENTION[0001]The present invention relates to a textile treatment composition.BACKGROUND OF THE INVENTION[0002]Recent increasing awareness of aroma promotes development of a method for imparting and sustaining an aroma in a washed textile product by treating the textile product with a textile treating agent such as a detergent and a fabric conditioner containing a fragrance having long lasting odor. In such a method, fragrance materials that are lipophilic and hardly volatile to transpire are generally used. These materials insufficiently release aromas and often have heavy aromas, and thus determine residual aroma tones. In contrast, hydrophilic and relatively hydrophilic fragrance materials sufficiently release aromas and have wider variety of materials than lipophilic fragrance materials, and thus enable to design various aromas. However, these hydrophilic materials have poor adsorption on textile, and thus provide weak aromas to a treated textile product with less...
