Description

Fabric softener composition

The present invention relates to a fabric softener composition having improved loosening property in washing and rinsing water.

Fabric softeners are widely used in homes to prevent static electricity generated in clothing and to give the flexibility of the fiber, the amount of use is increasing gradually. Recently, with the improvement of consumer's living standard, the desire for hygiene and cleanliness increases and the pursuit of more comfortable medical life is increasing interest in preventing microbial growth and odor removal which can occur in clothing.

In general, the odor that occurs in fibers is caused by the mixing of organic compounds such as sweat and volatile organic compounds such as unsaturated lower fatty acids and ammonia, which are decomposed into skin flora, and the residual components of laundry detergents and fabric softeners. In particular, the drying time is delayed during the dry season during the rainy season, it is known that more odor is caused by the odor bacteria Morxella asloensis .

In order to remove such odors, a conventional softening agent composition containing an antimicrobial agent was used, but the antimicrobial agent included in the conventional softening agent is harmful to the human body. Recently, the use of synthetic antimicrobials has been reported to be harmful to the human body, so the use of such antimicrobials is being avoided.

In addition, fabric softeners have used cationic surfactants as flexible components for over 60 years since they were commercialized worldwide in the 1950s. However, recently, the human hazard of such cationic surfactants has been revealed, and the desire to avoid them is increasing.

In addition, the fabric softener has a disadvantage that if the viscosity is high, the diffusion (unwinding) of the organic acid in the wash water may be delayed to sufficiently exert the effect of the organic acid.

Korean Patent Publication No. 10-2007-0090861

The present invention does not use a cationic surfactant, which is included as a flexible component in the conventional fabric softener composition, but adds an organic acid, improves the loosening property of the organic acid by using a thickening polymer, and calcium carbonate, which is a detergent insoluble component remaining in the garment. An object of the present invention is to provide a fabric softener composition having excellent dissolution and removal effect.

In order to achieve the above object, the present invention provides a fabric softener composition comprising an organic acid and a thickening polymer, the viscosity of 1 to 250 cPs measured at 25 ℃, 60 rpm with a rotating viscometer.

The fabric softener composition according to the present invention uses an organic acid, but adds a polymer for thickening to improve the loosening property of the organic acid in a short washing / rinsing time, and is very effective in dissolving and removing calcium carbonate, which is a detergent insoluble component remaining in the garment. .

Hereinafter, the structure of this invention is demonstrated concretely.

The present invention relates to a fabric softener composition comprising an organic acid and a thickening polymer and having a viscosity of 1 to 250 cPs measured at 25 ° C. and 60 rpm with a rotating viscometer.

If the viscosity is high, the diffusion (relaxing) of the organic acid in the wash water is delayed, and thus the effect of the organic acid cannot be sufficiently exhibited. It is characterized by an improved one.

In the present invention, the organic acid serves to remove detergent residues, specifically calcium carbonate. In addition, the organic acid serves as a softener intrinsic (to soften the cloth and to feel good).

The organic acid may be, for example, citric acid, acetic acid, tartaric acid, succinic acid, malic acid or lactic acid or the like, but is not particularly limited thereto. Preferably, the organic acid may be citric acid. Since citric acid has a low unit cost of raw material costs, it is possible to reduce the production cost of the fabric softener composition.

The content of the organic acid is not particularly limited and may be included in an amount of 5 to 30 wt%, more specifically, 10 to 25 wt%, and more specifically 15 to 20 wt%, based on 100 wt% of the fabric softener composition. It can exhibit an excellent calcium carbonate removal effect within the above range. Even when the content of the organic acid exceeds 30% by weight exhibits excellent calcium carbonate removal effect, the higher the content of the organic acid, the lower the pH of the rinsing water, it is better to use less than 30% by weight.

The fabric softener composition of the present invention includes a thickening polymer capable of adjusting the viscosity to improve the loosening property of the organic acid. In the present invention, the thickening polymer is calcium-carboxymethyl cellulose, methyl cellulose / hydroxypropylmethylcellulose, hydroxyethyl cellulose, carbopol 934, carbopol 941, xanthan gum, sodium Alginate, guar gum, carrageenan, pectin, acrylic polymer, etc. can be used. Preferably, at least one acrylic polymer selected from the group consisting of acrylic acid polymers, acrylic copolymers, and acrylic acrylates is preferable.

The content of the thickening polymer is not particularly limited and may be included as 0.01 to 1.2% by weight, more specifically, 0.05 to 1% by weight based on 100% by weight of the fabric softener composition. Within the above range, the loosening property of the organic acid is improved and the calcium carbonate removal effect is excellent.

In addition, the thickening polymer is a factor for controlling the viscosity of the fabric softener composition of the present invention, and more specifically, when measured at 25 ° C. and 60 rpm with a rotatable viscometer, the viscosity may be 1 to 250 cPs. When the viscosity is greater than 250 cPs, the loosening of the diffusion of the organic acid in the washing / rinsing water may be poor, and thus it may not be easy to remove the remaining calcium carbonate in the garment.

The composition according to the present invention is excellent in detergent debris removal effect without using a cationic surfactant by using an organic acid and a polymer for thickening, and can be easily used as a fabric softener.

In one embodiment, when providing the fabric softener composition according to the present invention to wash / rinse water, the calcium carbonate remaining in the garment is completely removed.

The fabric softener composition according to the present invention may further include vinegar in addition to the aforementioned organic acid and the thickening polymer.

Vinegar is a sour and slightly sweet seasoning that contains acetic acid as its main ingredient, and contains dozens of organic acids such as acetic acid, citric acid, and various amino acids, which help to boost metabolism and remove body wastes, It serves as a powerful fungicide. In addition, vinegar may serve to remove detergent residues.

The content of the vinegar is not particularly limited and may be included in 0.1 to 10% by weight, 0.5 to 5% by weight or 1 to 3% by weight relative to 100% by weight of the fabric softener composition. It has a bactericidal effect and an effect of removing detergent residues within the above range.

The fabric softener composition according to the present invention may further include a flower fermentation vinegar that plays a role of a strong deodorant in addition to the above-described composition.

The flower fermentation vinegar may be obtained by washing the petals with water, dried and mixed with excess vinegar and sugar fermentation for 3 to 7 days.

The vinegar may be commercially available vinegar, it is preferable to use 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 sugar serves to alcohol ferment the flower extract, it is preferred to use 5 to 30 parts by weight based on 1 part by weight of the petals.

Alternatively, the flower fermentation vinegar is sterilized with the original flower, hot water extracted for 10 to 30 minutes at 100 to 150 ℃ and then mixed with the hot water extract and vinegar and sugar and fermentation process at 20 to 40 ℃ for 72 to 96 hours Can be obtained through

The vinegar refers to fermented by propagating wild vinegar isolated from vinegar, odorless (이미) produced in the traditional manner, the seed vinegar by the acetic acid bacteria Acetobacter sp. Anything that can be produced can be used. In this case, the amount of the seed may be added in 5 to 30% by weight relative to 100% by weight of the hydrothermal extract. When the added amount of the vinegar is less than 5% by weight, it is difficult to induce vinegar fermentation of the aged hydrothermal extract, and when it exceeds 30% by weight, the efficiency of vinegar fermentation does not increase any more.

The sugar may include various sugars such as glucose, sugar, fructose, oligosaccharide, or syrup. The sugar serves to ferment the flower hydrothermal extract alcohol, and may be added in an amount of 5 to 30% by weight based on 100% by weight of the hydrothermal extract flower.
