[0001] Perfume composition for laundry [0002]

The present invention relates to a perfume composition for laundry, and more particularly, to a perfume composition for laundry, which is mainly used to improve the storage stability of a fabric softener when washing clothes or the like, , Or when the laundry is washed without using the fabric softener, the laundry is added to the washing water to remove the detergent odor and other unpleasant odors remaining in the laundry and to maintain the fragrance for a long time.

As the living standards of consumers have improved recently and the desire for hygiene and cleanliness has increased, there has been an increasing interest in preventing the growth of microorganisms and the unpleasant smell that may occur during washing of clothes. Generally, unpleasant odor generated in clothes is caused by reaction with volatile organic compounds such as unsaturated lower fatty acid and ammonia, which are formed by decomposition of skin granules and organic compounds contained in perspiration secreted from human body, or by reacting with residues of laundry detergent .

It is increasingly assumed that fabric softeners are used in the washing process in accordance with these social demands. The fabric softener prevents the static electricity generated from the clothes, imparts flexibility to the fibers, and further maintains the fragrance for a long time after various washing. Conventionally, a fabric softener composition containing an antimicrobial agent has been used to remove odor bacteria distributed in fiber tissues. However, since these antibacterial agents are known to be harmful to humans, efforts to develop a fabric softener harmless to humans have been variously attempted have.

For example, Korean Patent No. 10-1336088 (Nov. 27, 2013) discloses a fabric softener composition comprising tea saponin quarternary ammonium salt quarternary ammonium salt extracted from tea seeds as an active ingredient No. 10-1502443 (Mar. 09, 2015) discloses a fabric softener composition comprising a surfactant having a structure in which four hydroxyl groups are contained and three ammonium salts are linked to each other. 1517039 (Apr. 27, 2015) discloses a fabric softener composition comprising a surfactant containing two ester groups and two ammonium salts linked together.

As described above, a conventional fabric softening agent containing a surfactant as a main component has an effect of preventing static electricity and imparting flexibility to fibers, but the fabric softener composition to which a perfume ingredient is added has also been introduced because of lack of directional effect. For example, in Korean Patent No. 10-1188300 (Sep. 27, 2012), 3 to 7% by weight of a cationic surfactant, 30 to 60% by weight of sodium bicarbonate, an oak tree, fennel, A foamed powdery fiber comprising 0.05 to 1 wt% of mixed extract powder, 0.05 to 0.1 wt% of eucalyptus oil powder, 0.05 to 0.1 wt% of grapefruit seed oil extract, 2 to 3 wt% of flavoring agent and 30 to 60 wt% Softening agent compositions have been disclosed in Japanese Patent Application Laid-Open No. 10-2015-0100541 (Sep. 02, 2015). In the case of using a fatty acid to which ethylene oxide is added and a fatty alcohol to which ethylene oxide has been added as a solubilizer, A fabric softener composition is disclosed which removes water.

These directional fabric softeners are mixed with a cationic surfactant and a perfume component. When these components are mixed with each other over time, they often chemically interfere with each other to cause denaturation. For example, the fragrance component may be altered to exhibit an unintended flavor, or the cationic surfactant, especially the ester bond-containing cationic surfactants, may be hydrolyzed and separated into fatty acids by the flavor component, May lose the role of

In order to solve such a problem, Korean Patent Laid-Open No. 10-2015-0111778 (Oct. 06, 2015) allows the user to easily select a desired fragrance and mix the fragrance as desired, thereby improving the stability of the fabric softener and the satisfaction of the fragrance A fiber additive for textile softeners has been introduced.

Registration No. 10-1336088 (November 27, 2013) Registration No. 10-1502443 (March 09, 2015) Registration No. 10-1517039 (Apr. 27, 2015) Registration No. 10-1188300 (September 27, 2012) Open Patent No. 10-2015-0100541 (September 02, 2015) Open Patent No. 10-2015-0111778 (Oct. 06, 2015)

Accordingly, a problem to be solved by the present invention is to provide a laundry detergent composition capable of imparting a fragrance to laundry and sustaining its fragrance for a long time when the skin is so sensitive as an infant or an atopic patient that the conventional directional fabric softener is not used, To provide a perfume composition.

Another object of the present invention is to provide a fabric softener which can be easily added and used in accordance with the user's preference or selection when washing with a fabric softener which excludes perfume ingredients for the purpose of ensuring the storage stability of the fabric softener And to provide a perfume composition for laundry.

The fragrance composition for laundry according to the present invention comprises 40 to 55% by weight of a perfume, 30 to 45% by weight of polysorbate-20, 5 to 15% by weight of propylene glycol, 3 to 5% by weight of ethanol, -67 0.5 to 2% by weight.

The fragrance composition for laundry according to a preferred embodiment of the present invention is characterized in that the benzyl is selected from the group consisting of 48% by weight of fragrance containing soogenic, 35% by weight of polysorbate-20, 12% by weight of propylene glycol, , And 1 wt% of polyquaternium-67.

The fragrance composition for laundry according to the present invention can be added to a fabric softener having a fragrant component removed in order to improve the storage stability of a conventional fabric softener and can be added to the washing water when the laundry is not used, It is possible to remove the detergent odor and other unpleasant odors remaining in the laundry and to maintain the fragrance for a long time.

Hereinafter, the present invention will be described in detail. The components of the perfume composition for laundry according to the present invention are composed of a perfume and polysorbate-20, propylene glycol, ethanol, and polyquaternium-67.

First, the fragrance serves to provide a fragrance to the laundry. Any one of fragrance that can be used in conventional fabric softeners can be used. For example, benzyl isoquinol, dimethyl anthranilate (2-methyl-aminomethyl benzoate), cetyl acetate, 5- (2-methylene-6,6-dimethylcyclohexyl) Methyl-4- (2,2,3-trimethyl-3-1-yl) -2-butene-1-ol, tricyclodecyl propiolate, tricyclodecylnyl acetat, Methyl-3- (trimethyl-2,2,3-cyclopenten-3-yl-1) - (2,2-dimethyl-2,2,3,3-tetramethyldodecahydronaphtho [2,1- Pentanol-2,2,6-dinitro-3,4,5-trimethyl-tert-butylbenzene, 2-acetyl-1,2,3,4,5,6,7,8-octahydro P-tert-butyl-methylhydroxamic aldehyde, trichloromethylphenylvinyl acetate,? -Naphthol methyl ether, acetyl cetylene, anisyl acetone (p-methoxy Phenylbutanone) and 4- (4-hydroxy-4-methylpentyl-3-cyclohexene-1-carboxyaldehyde) Standing benzyl is preferred to use this Sources play.

If the content is less than 40% by weight, the aroma provided to the laundry is too weak to be meaningful. On the contrary, if the content exceeds 55% by weight, the content of the other components There is a problem that the content of the surfactant is too small and the overall balance is lost.

Next, the polysorbate-20 functions to emulsify the fragrance and uniformly disperse the fragrance. Polysorbate is a polyoxyethylene higher aliphatic alcohol in which ethylene oxide is bonded to a sorbitan fatty acid ester and is a kind of nonionic surfactant. The polysorbate is selected from the group consisting of polysorbate-20 (monolauric acid), 40 (monopalmitic acid), 60 (monostearic acid) and 65 (tristearic acid) depending on the number of polyoxyethylene groups and fatty acid differences. , 80 (monooleic acid), and the like. In the present invention, polysorbate-20 (monolauric acid) is used.

Risorvate-20 is a yellow or yellowish brown liquid with a bitter taste, similar to a mint flavor, and is used as a surfactant or emulsifier in general detergents and cosmetics.

The content of the polysorbate-20 is 30 to 45% by weight. If the content of the polysorbate-20 is less than 30% by weight, the fragrance may not be uniformly dispersed. On the contrary, if the content exceeds 45% There is a fear that the fragrance supplied to the laundry becomes too weak.

The propylene glycol serves as a solvent to stabilize other components so as not to cause chemical modification. The propylene glycol is a colorless transparent syrupy liquid and has no odor or odor, has a slightly bitter and sweet taste, and is widely used as a spreading agent for bread, a moisturizer, and an extension agent for shortening.

If the content of the propylene glycol is less than 5% by weight, the long-term storage stability of the perfume composition according to the present invention is greatly reduced. On the other hand, if the content exceeds 15% by weight, Which is undesirable.

The above-mentioned ethanol also functions as a solvent to stabilize other components not to cause chemical modification. The ethanol is a colorless liquid having volatility and flammability, which is an alcohol in which one hydrogen atom is substituted with a hydroxy group in an ethene having two carbon atoms in a chain-like hydrocarbon. As it is well known, it is also called 'alcohol' as the main ingredient of alcohol. The content of the ethanol is preferably 3 to 5% by weight.

Finally, the polyquaternium-67 functions to keep the fragrance by keeping the fragrance in the fiber structure of the laundry for a long time. The polyquaternium-67 is an INCI common name for a polymeric quaternary ammonium salt of hydroxyethyl cellulose reacted with an epoxide substituted with trimethylammonium and an epoxide substituted with lauryldimethylammonium (dimethyldodecyl). Polyquaternium-67 is available under the trade designation 'SoftCAT' from Armor Company, a subsidiary of Dow Chemical Company.

The content of the polyquaternium-67 is 0.5 to 2% by weight. If the content of the polyquaternium-67 is less than 0.5% by weight, the persistence of the perfume after the drying of the laundry is weak. On the other hand, The synergistic effect with increasing content is insignificant.

The fragrance composition for laundry according to the present invention may be added to the conventional fabric softener to improve the preservation safety when the fabric softener excluded from the fragrance component is used or the laundry may be used when the skin is so sensitive that the fabric softener is not used It may be added to the washing water in an appropriate amount.

Hereinafter, an embodiment of the present invention will be described.
