Description

[0001] Fabric softener composition [0002]

The present invention relates to a fabric softener composition.

Textile softeners are widely used in households to prevent static electricity generated in clothes and to impart flexibility to fibers, and the amount thereof is gradually increasing. In recent years, there has been an increasing interest in prevention of the growth of microorganisms and the removal of offensive odors, as consumers' living standards are improved, hygienic and cleanliness requirements are increased, and more comfortable lifestyle is pursued.

Generally, the organic odor generated in fibers is caused by organic compounds such as sweat odor reacting with volatile organic compounds such as unsaturated lower fatty acids and ammonia formed by decomposition of the skin upright bacteria or reacting with laundry detergent or residues of fabric softener . Especially in the case of rainy season, drying time is delayed during drying in the room, so it is known that odor generated by Morxella asloensis, which is an odor bacterium, is generated more.

Conventionally, a fabric softener composition containing an antimicrobial agent has been used to remove such odor, but the antimicrobial agent contained in the conventional fabric softener is harmful to human body. In recent years, the use of synthetic antimicrobial agents has been reported to be harmful to human body. Therefore, the use of such antimicrobial agents is being avoided.

In addition, textile softeners have been commercially available worldwide in the 1950s and have used cationic surfactants as softening agents for over 60 years (Patent Document 1). However, recently, such a cationic surfactant has been found to be toxic to human body, and the desire to avoid it is increasing.

It is an object of the present invention to provide a fabric softener composition having a high flavor satisfaction by alleviating vinegar stalks by retaining a transparent phase by solubilizing a flavor in a fabric softener containing an organic acid and a fermented vinegar without using a cationic surfactant .

The present invention includes an organic acid, a fermented vinegar, and a solubilizing agent,

Wherein the solubilizing agent comprises a fatty alcohol to which ethylene oxide is added and a fatty alcohol to which ethylene oxide is added.

INDUSTRIAL APPLICABILITY The fabric softener composition according to the present invention is excellent in fragrance satisfaction by using a solubilizing agent together with an organic acid and a fermented vinegar without using a cationic surfactant, maintaining a transparent phase and alleviating vinegar odor.

The present invention includes organic acids, fermented vinegar and solubilizing agents,

The solubilizing agent relates to a fabric softener composition comprising a fatty acid to which ethylene oxide is added and a fatty alcohol to which ethylene oxide is added.

Hereinafter, the fabric softener composition according to the present invention will be described in more detail.

The fabric softener composition according to the present invention includes organic acid, fermented vinegar, and solubilizing agent as described above.

In the present invention, the organic acid plays a role of removing deodorant and detergent residue. In addition, the organic acid acts as a softening agent (softens the fabric and improves the feel). The kind of the organic acid is not particularly limited and may include at least one selected from the group consisting of citric acid, acetic acid, tartaric acid, succinic acid, malic acid and lactic acid.

The higher the acidity of the organic acid, the better the deodorizing power. The lower the pKa value is, the lower the pH of the aqueous solution is. Therefore, the use of an organic acid having a low pKa value can increase the deodorizing power of the fabric softening agent. Since the pKa of the citric acid is 3.1, the malic acid is 3.4 and the acetic acid is 4.8, it is advantageous to use citric acid as the organic acid in the present invention. In particular, citric acid is suitable for use as an organic acid because the unit cost of the raw material is low.

The content of the organic acid is not particularly limited and may be 1 to 30% by weight, 5 to 20% by weight or 8 to 15% by weight based on 100% by weight of the fabric softener composition. Exhibits excellent deodorizing power within the above range, and is effective for removing detergent residue. Even when the content of citric acid is 30% by weight or more, excellent deodorizing power is exhibited. However, the higher the content of citric acid, the lower the pH of the rinse water.

In the present invention, the fermented vinegar plays a role of strong deodorization.

The kind of fermented vinegar is not particularly limited, and for example, flower fermented vinegar can be used.

The fabric softener composition according to the present invention may further comprise a flower fermented vinegar which plays a role of strong deodorization in addition to the above-mentioned composition components.

The flower fermented vinegar may be one obtained by washing the petal with water, drying it, mixing it with excess vinegar and sugar, and fermenting it for 3 to 7 days.

The vinegar may be a commercial vinegar, and is preferably used in an amount of 5 to 30 parts by weight based on 1 part by weight of the petals. In addition, the sugar may include various sugars such as glucose, sugar, fructose, oligosaccharide, or syrup. The saccharide may be used to ferment flower extracts to alcohol, and preferably 5 to 30 parts by weight per 1 part by weight of the petals.

Alternatively, the flower fermented vinegar may be prepared by sterilizing flower buds, hydrothermally extracting at 100 to 150 ° C for 10 to 30 minutes, mixing the hot-water extract with herbaceous powders and sugar, and then fermenting at 20 to 40 ° C for 72 to 96 hours .

The above-mentioned herbaceous plant is a plant produced by fermentation of wild-cauliflower bacteria isolated from a traditional vinegar vinegar without any odor and odor, and the herbaceous plant is fermented by a wild-type acetic acid bacteria Acetobacter sp. Any that can be produced can be used. At this time, the amount of the seeds may be added in an amount of 5 to 30% by weight based on 100% by weight of the flower hot-water extract. If the addition amount of the seeds is less than 5 wt%, it is difficult to induce vinegar fermentation of the agar-agaric hot-water extract, and if it exceeds 30 wt%, the efficiency of vinegar fermentation does not increase more than the addition amount.

The sugar may be various sugars such as glucose, sugar, fructose, oligosaccharide, or syrup. The saccharide may be added in an amount of 5 to 30% by weight based on 100% by weight of the flower hot-water extract.

The flower fermented vinegar prepared by the above method may have a pH of 2.70 to 3.30 and an acidity of 3 to 7. [

The kinds of flowers used in the flower fermentation vinegar preparation can be used without limitation. For example, red flowers, apricot flowers, acacia flowers, chamomile flowers, jasmine flowers or lotus flowers can be used.

The content of the fermented vinegar is not particularly limited and may be 0.001 to 10% by weight, 0.05 to 5% by weight or 0.1 to 2% by weight based on 100% by weight of the fabric softener composition. Within this range, the sterilizing power is excellent and the smell can be easily removed.

In the present invention, the solubilizer alleviates vinegar pickling by fermentation vinegar or the like, thereby improving the satisfaction of the fragrance of the fabric softener.

As such a solubilizing agent, a nonionic surfactant can be used. Specifically, a fatty acid to which ethylene oxide is added and a fatty alcohol to which ethylene oxide is added can be used.

Conventional fabric softening agents include cationic surfactants and flavoring agents, which are used to stabilize such cationic surfactants and flavors, and nonionic surfactants to which ethylene oxide is added to fatty alcohols as the solubilizing agent. In this case, the cationic surfactant, the perfume, and the nonionic surfactant formed a vesicle structure in which emulsified particles were formed, and the stability was maintained.

However, as in the present invention, when organic acid and fermented vinegar are used instead of the cationic surfactant, the liquid softener composition has an acidity of less than pH 3, so that when the nonionic surfactant is used, The components may be deformed, and there may be a problem that the fragrance due to the vinegar component is unsatisfactory and the merchantability is lowered.

Accordingly, in the present invention, a mixture of a fatty acid to which ethylene oxide is added as a solubilizing agent and a fatty alcohol to which ethylene oxide is added may be used as a solubilizing agent in order to improve odor satisfaction by removing odor by a vinegar component and to improve the stability of a fabric softener .

The fatty acid to which ethylene oxide is added may specifically be a nonionic surfactant to which ethylene oxide is added to a fatty acid having a linear or branched alkyl group or alkenyl group having 10 to 20 carbon atoms and more specifically, EO addition.

The fatty alcohol to which ethylene oxide is added may specifically be a nonionic surfactant to which ethylene oxide is added to a fatty alcohol having a straight chain or branched alkyl group or alkenyl group having 10 to 20 carbon atoms. More specifically, Polyoxyethylene alkyl ethers.

The content of the solubilizing agent is not particularly limited and may be 1 to 10% by weight, 2 to 8% by weight or 3 to 5% by weight based on 100% by weight of the fabric softener composition. Within the above range, the effect of removing vinegar stains is excellent, so that the degree of perfume can be enhanced and the stability of the fabric softener can be enhanced.

Further, the ratio of the fatty acid to which ethylene oxide is added and the fatty alcohol to which ethylene oxide is added in the solubilizing agent may be 1: 0.1 to 1: 5 or 1: 0.3 to 1: 3.

Vinegar may further be used in the fabric softener composition of the present invention.

Vinegar is a seasoning containing acetic acid as its main ingredient and it has a sweet and bitter taste. It contains dozens of organic acids such as acetic acid, citric acid and various amino acids to activate the metabolism and eliminate the waste materials in the body, It also acts as a powerful disinfectant. In addition, the vinegar can perform the role of removing the detergent residue.

The content of the vinegar is not particularly limited and may be 0.1 to 10% by weight, 0.5 to 5% by weight or 1 to 3% by weight based on 100% by weight of the fabric softener composition. And has the effect of removing the sterilizing effect and the detergent residue within the above range.

In addition, the fabric softener composition according to the present invention may further comprise ethanol for phase stability of the contents.
