Description
Technical Field
The invention relates to a fiber softener composition.
Background
In order to prevent static electricity from being generated on clothes and to impart softness to fibers, a fiber softener is widely used in homes, and the amount of use thereof tends to be gradually increased. Recently, as the standard of living of consumers is improved, the demand for hygiene and cleanliness is gradually increased, and in pursuit of more comfortable wearing life, the interest in preventing the proliferation of microorganisms that may be generated on clothes and removing odor is gradually increased.
In general, the damp odor generated in the fibers can be generated by reacting organic compounds constituting sweat odor or the like with volatile organic compounds such as unsaturated lower fatty acids and ammonia generated by decomposition of normal skin flora, or with residual components of laundry detergents or softeners. It is known that especially when clothes are dried in a rainy season in a room, a damp smell is more likely to be generated due to the influence of odor bacteria Morxella asloensis because of a prolonged drying time.
In order to remove such a damp odor or the like, a fiber softener composition containing an antibacterial agent has been conventionally used, but the antibacterial agent contained in the conventional fiber softener is harmful to the human body. Recently, as the use of synthetic antibacterial agents harmful to the human body has been reported, the use of such antibacterial agents has been kept away from the public.
In addition, since the fiber softener became popular in 1950 s all over the world, a cationic surfactant was used as a softening ingredient for more than 60 years (Korean patent laid-open No. 10-2007-0090861). However, in recent years, the harmful effect of such cationic surfactants on the human body has been revealed, and the demand for the removal of such harmful substances has been increasing.

Detailed Description
The present invention relates to a fiber softener composition which contains a pH adjuster, does not contain a cationic surfactant, and has a residual calcium carbonate content of 90ppm or less in fibers washed and rinsed according to the environmental label EL306 test method (hereinafter referred to as "first fiber softener composition").
As the experimental method of the EL306, washing and rinsing may be performed according to a flexibility experimental method among the experimental methods of the EL 306.
In the present invention, the pH adjuster may function to remove the residue of the laundry detergent. In addition, the organic acid can play a role of a softener per se (softening the clothing, improving the touch).
The pH adjuster may be an organic acid, and the kind of the organic acid is not particularly limited, and may include one or more selected from the group consisting of citric acid, acetic acid, tartaric acid, succinic acid, malic acid, and lactic acid, for example.
The content of the pH regulator is not particularly limited, and the pH regulator may be contained in an amount of 1 to 30 wt%, 5 to 20 wt%, or 8 to 15 wt% with respect to 100 wt% of the fiber softener composition. Within the range, the pH adjustor can exhibit an excellent effect of removing calcium carbonate. Even if the content of the pH adjuster exceeds 30 wt%, the excellent effect of removing calcium carbonate can be exhibited, but the pH of the rinse water is lowered as the content of the pH adjuster is higher, and therefore, the amount of use is preferably 30 wt% or less.
According to the fabric softener composition of the present invention, the removal effect of the laundry detergent residue is excellent even if the cationic surfactant is not included, and thus it is conveniently used as a fabric softener.
As a specific example, in the present invention, the content of calcium carbonate remaining in the fiber after washing and rinsing according to the test method of environmental marker EL306 may be 90ppm or less, 65ppm or less, 50ppm or less, 45ppm or less, 40ppm or less, 37ppm or less, or 0 ppm.
In addition, in the invention, 5-300 ppm, 10-250 ppm or 30-200 ppm of calcium carbonate remained in the fiber after washing and rinsing according to the environmental label EL306 experiment method can be removed.
Further, the present invention relates to a fabric softener composition which contains a pH adjuster, does not contain a cationic surfactant, and has a residual zeolite content of 20ppm or less in fibers after washing and rinsing according to the environmental label EL306 test method (hereinafter referred to as "second fabric softener composition").
As the experimental method of the EL306, washing and rinsing may be performed according to a flexibility experimental method among the experimental methods of the EL 306.
In the present invention, the pH adjuster may function to remove laundry detergent residues, and particularly, may function to remove zeolite. In addition, the organic acid can play a role of a softener per se (softening the clothing, improving the touch).
The pH adjuster may be an organic acid, and the kind of the organic acid is not particularly limited, and may include one or more selected from the group consisting of citric acid, acetic acid, tartaric acid, succinic acid, malic acid, and lactic acid, for example.
The content of the pH regulator is not particularly limited, and the pH regulator may be contained in an amount of 1 to 30 wt%, 5 to 20 wt%, or 8 to 15 wt% with respect to 100 wt% of the fiber softener composition. Within the range, the pH adjustor can exhibit excellent zeolite removing effect. Even if the content of the pH adjuster exceeds 30 wt%, the excellent zeolite removing effect can be exhibited, but the pH of the rinse water is lowered as the content of the pH adjuster increases, and therefore, the amount of use is preferably 30 wt% or less.
According to the fabric softener composition of the present invention, the removal effect of the laundry detergent residue is excellent even if the cationic surfactant is not included, and thus it is conveniently used as a fabric softener.
As a specific example, in the present invention, the content of the zeolite remaining in the fiber after washing and rinsing according to the test method of environmental designation EL306 may be 20ppm or less, 10ppm or less, 8ppm or less, 7ppm or less, 3ppm or less, or 0 ppm.
In addition, in the present invention, 5 to 300ppm, 10 to 250ppm, or 30 to 200ppm of zeolite remaining in the fiber after washing and rinsing according to the environmental label EL306 test method can be removed.
The present invention also relates to a fiber softener composition which contains a pH adjuster, does not contain a cationic surfactant, and has a fiber friction coefficient of 2 to 25 after washing and rinsing according to the test method of environmental label EL306 (hereinafter referred to as "third fiber softener composition").
As the experimental method of the EL306, washing and rinsing may be performed according to a flexibility experimental method among the experimental methods of the EL 306.
In the present invention, the pH adjuster may function to remove the residue of the laundry detergent. In addition, the organic acid can play a role of a softener per se (softening the clothing, improving the touch).
The pH adjuster may be an organic acid. The type of these organic acids is not particularly limited, and may include, for example, one or more selected from the group consisting of citric acid, acetic acid, tartaric acid, succinic acid, malic acid, and lactic acid.
The content of the pH adjuster is not particularly limited, and the pH adjuster may be included in an amount of 1 to 30 wt%, 5 to 20 wt%, or 8 to 15 wt% with respect to 100 wt% of the fabric softener composition. Within the range, the pH adjustor can exhibit an excellent effect of removing calcium carbonate. Even if the content of the pH adjuster exceeds 30 wt%, the excellent effect of removing calcium carbonate can be exhibited, but the pH of the rinse water is lowered as the content of the pH adjuster increases, and therefore, the amount of use is preferably 30 wt% or less.
According to the fabric softener composition of the present invention, the removal effect of the laundry detergent residue is excellent even if the cationic surfactant is not included, and thus it is conveniently used as a fabric softener.
As a specific example, in the present invention, the fiber friction coefficient after washing and rinsing according to the experimental method of the environmental label EL306 may be 2 to 25, 10 to 25, or 20 to 23. Within the range of the friction coefficient, the dried object does not stick and slip and can give a dry and soft feeling. The subject may be a subject to which a fabric softener such as clothes is applied.
The present invention also relates to a fabric softener composition which contains a pH adjuster, does not contain a cationic surfactant, and has a water repellency of 4 or more after repeating rinsing/dewatering 5 times depending on the amount of the environmental label EL306 used (hereinafter referred to as "fourth fabric softener composition").
As described above, the fabric softener composition according to the present invention includes a pH adjuster.
In the invention, the pH regulator plays a role in water repellency and moisture permeability for outdoor clothes made of Golters fabric. The pH adjuster may be an organic acid. In addition, the organic acid functions as a softener itself (to soften the cloth and improve the touch). The type of these organic acids is not particularly limited, and may include, for example, one or more selected from the group consisting of citric acid, acetic acid, tartaric acid, succinic acid, malic acid, and lactic acid. In particular, citric acid is suitable as an organic acid because of its relatively low cost as a raw material.
The content of the pH regulator is not particularly limited, and the pH regulator may be contained in an amount of 0.01 to 30 wt%, 0.1 to 20 wt%, or 1 to 15 wt% with respect to 100 wt% of the fabric softener composition. Within the range, the excellent water repellent and moisture permeable effects of outdoor clothing made of the Golters fabric can be achieved. Even if the content of the organic acid exceeds 30 wt%, the golts fabric outdoor clothing can still exhibit excellent water repellency and moisture permeability, but the amount of the organic acid used is preferably 30 wt% or less because the pH of the rinse water decreases as the content of the organic acid increases.
The fiber softener composition according to the invention does not contain a cationic surfactant, can still have excellent water repellency and moisture permeability effects on Golters fabric outdoor clothes, and is convenient to use as a fiber softener.
In one embodiment, the fabric softener composition of the present invention has a water repellency of 4 or more after repeated 5 rinses/dehydrations with the environmental label EL 306.
The present invention also relates to a fabric softener composition which contains an organic acid, does not contain a cationic surfactant, and has a sensory evaluation of 4 points or more (hereinafter, referred to as "fifth fabric softener") on a wet odor 5 point scale after being left for 24 hours under conditions of a drying temperature of 30 ℃ and a relative humidity of 80% after being washed under the environmental label EL 306.
The fabric softener composition of the present invention is characterized in that the damp smell after washing is removed by using an organic acid instead of a cationic surfactant.
In the present invention, the organic acid functions to remove residues of the laundry detergent, specifically, calcium carbonate. In addition, the organic acid functions as a softener itself (to soften the cloth and improve the touch).
As the organic acid, for example, one or more of citric acid, acetic acid, tartaric acid, succinic acid, malic acid, lactic acid, and the like can be used, but the organic acid is not limited thereto. Preferably, the organic acid may be citric acid. Since the cost of the raw material of the citric acid is low, the production cost of the fiber softener composition can be saved.
The content of the organic acid is not particularly limited, and the organic acid may be contained in an amount of 1 to 30 wt%, more specifically, 2 to 25 wt%, with respect to 100 wt% of the fabric softener composition. Within the range, an excellent effect of removing calcium carbonate can be exhibited. Even if the content of the organic acid exceeds 30% by weight, the excellent effect of removing calcium carbonate can be exhibited, but the pH of the rinse water is lowered as the content of the organic acid is increased, and therefore, the amount of the organic acid used is preferably 30% by weight or less.
The fabric softener composition of the present invention uses an organic acid instead of a cationic surfactant, and can effectively remove a wet odor by a sensory evaluation of 4 points or more on a wet odor 5 point scale after being washed according to the environmental label EL306 and left to stand for 24 hours under conditions of a drying temperature of 30 ℃ and a relative humidity of 80%. Therefore, the fabric softener is convenient to use.
The fabric softener composition according to the present invention may contain a thickening polymer for adjusting viscosity in addition to all the above organic acids.
As the thickening polymer, carboxymethylcellulose calcium, methylcellulose/hydroxypropylmethylcellulose, hydroxyethylcellulose, carbomer 934(carbopol 934), carbomer 941(carbopol 941), xanthan gum, sodium alginate, guar gum, carrageenan, Pectin (Pectin), an acrylic polymer, and the like can be used.

TABLE 1
Experimental example 1: measurement of residual calcium carbonate content in laundry after washing
After washing and rinsing using the fiber softener compositions prepared by the above examples and comparative examples, the content of calcium carbonate remaining in the clothes was measured.
3 pieces of white standard cotton cloth (10X 10cm) specified in KS K0905 were used as clothes, and a commercially available powdery detergent containing calcium carbonate (LG Life health, tech: (L) (R))
Trade name)).
The washing was performed according to the experimental method of EL306 (fiber softener) in the environmental label certification standards of the korean environmental industry technology institute, and the amount of the fiber softener composition used at the last rinsing was 0.67 mL/L.
The residual amount of calcium carbonate remaining in the washed and rinsed clothes was analyzed by separating 0.5g of the washed and rinsed cotton cloth, subjecting the cotton cloth to acid treatment with a mixed solution of hydrochloric acid, hydrofluoric acid, nitric acid and boric acid, extracting the cotton cloth for 24 hours, and analyzing the cotton cloth by ICP (high frequency inductively coupled plasma).

It was confirmed that in comparative examples 1 and 2, which were rinsed with water or a standard fabric softener, calcium carbonate, which is a water-insoluble component in the laundry detergent, could not be removed, and thus the amount of calcium carbonate remaining in the laundry was large. Whereas in the example of rinsing with the organic acid-containing fabric softener composition, the residual amount of calcium carbonate in the laundry was significantly reduced due to the dissolution of calcium carbonate by the fabric softener composition.
Further, it was confirmed that the fiber softener composition using citric acid among organic acids was excellent in calcium carbonate removal effect, while comparative example 3 using a cationic surfactant in an amount equivalent to that of the organic acids did not have calcium carbonate removal effect.
Experimental example 2: measurement of residual zeolite content in laundry after washing
The residual zeolite content in the clothes was measured after washing and rinsing using the fabric softener compositions prepared by the above examples and comparative examples.
3 pieces of white cotton standard cloth (10X 10cm) specified in KS K0905 were used for clothes, and a commercially available zeolite-containing powdery detergent (LG Life health, tech: (L))
Trade name)).
The washing was performed according to the experimental method of EL306 (fiber softener) in the environmental label certification standards of the korean environmental industry technology institute, and the amount of the fiber softener composition used at the last rinsing was 0.67 mL/L.
The residual amount of zeolite remaining in the clothes after washing and rinsing was analyzed by taking 0.5g of the cotton cloth after washing and rinsing, subjecting it to acid treatment with a mixed solution of hydrochloric acid, hydrofluoric acid, nitric acid and boric acid, extracting it for 24 hours, and analyzing it by ICP (high frequency inductively coupled plasma).

The measurement conditions of the friction coefficient of the laundry after washing were: the moving speed was 25cm/min, the weight of the hammer was 160g, and the sponge pad (puff) used was Nitrile Butadiene Rubber (NBR). The load (load) generated when the hammer was moved at a fixed speed was measured after placing the treated standard cotton cloth on the test plate and placing the hammer.
For the stick-slip index, it was performed by sensory evaluation by 10 special supervisors, and 5 was classified as the most stick-slip.
The coefficient of friction and stick-slip index of the laundry were measured, and the measurement results are shown in table 7 below.
TABLE 7
It was confirmed that in comparative example 1, which used only water rinsing, the coefficient of friction was high and the surface was excessively rough. In addition, comparative example 2, which was rinsed with a standard fabric softener, and comparative example 3, which was rinsed with a fabric softener containing a cationic surfactant, showed very slimy slip. When the fabric softener composition of the embodiment to which the cationic surfactant is not added and the pH adjuster, i.e., the organic acid is added, is used, the clothes are not too rough and not sticky and slippery, giving a dry and soft feeling.
Examples 16 to 21
A fabric softener composition having the composition and content shown in table 8 below was prepared.
Firstly, citric acid, edible vinegar and flower fermented vinegar are put into refined water and stirred for 30 minutes, and then a solution dissolved with ethanol, a fragrance solubilizer and a defoaming agent is added into the refined water and stirred for 30 minutes to prepare the fiber softener composition.
The pH adjuster uses 0.1-20 wt% of citric acid in organic acid.
In addition, brewed vinegar (natural food) is used as the edible vinegar.
The flower fermented vinegar used was prepared by washing jasmine petals with water, drying, mixing 1 part by weight of edible vinegar and 15 parts by weight of sugar water with respect to the petals with the dried petals, and naturally fermenting for about 7 days.
Comparative example 5
A fabric softener composition having the composition and content shown in table 8 below was prepared.
First, a cationic surfactant was added to purified water and stirred for 30 minutes, and then a solution in which ethanol, a fragrance solubilizer, and a defoaming agent were dissolved was added thereto and stirred for 30 minutes to prepare a fabric softener composition.
As the cationic surfactant, TEA Ester Quaternary (INCI Name: dehydrated lipophilic ammonium methyl sulfate, active 90%) was used.
TABLE 8
Experimental example 4: water repellency measurement of outdoor clothing made of Goerts fabric
Using the fiber softener compositions prepared by the above examples and comparative examples, the water repellency of golts fabric outdoor garments was measured.
In the experiment, commercial Golter fabric clothes (GORE-TEX cover of ISUKA) were directly purchased as Golter used]The laundry detergent uses LG healthy-living tech ()
Trade name).
The determination standard of the water repellency is AATCC (american society for fiber chemical dyeing) standard, and is classified into 5 (no adhesion or wetting of the surface), 4 (little adhesion or wetting of the surface), 3 (wetting of the surface is shown where water is sprinkled), 2 (partial wetting occurs over the entire surface), and 1 (complete wetting of the surface).
The measurement results of the water repellency of the golts fabric outdoor garment are shown in table 9.
TABLE 9
| Distinguishing | Water repellency rating |
| Example 16 | 4 |
| Example 17 | 4 |
| Example 18 | 4 |
| Example 19 | 4 |
| Example 20 | 4 |
| Example 21 | 4 |
| Comparative example 1 | 4 |
| Comparative example 2 | 1 |
| Comparative example 5 | 1 |
As can be seen from table 9 above, in comparative example 5 in which the cationic surfactant was added, the cationic surfactant was attached to the golts fabric, the contact angle of water was lowered, and the water repellency function was significantly lowered. In comparative example 2 using a standard fabric softener, the water repellent function was also significantly reduced. However, the water repellent function was not lowered in comparative example 1 using only water and examples 16 to 21 to which no cationic surfactant was added.
Examples 22 to 26
A fabric softener composition having the composition and content shown in table 10 below was prepared.
First, the thickening polymer was put into refined water, sufficiently stirred until completely dissolved, then citric acid, table vinegar and flower fermented vinegar were added thereto and stirred for 30 minutes, and then a solution in which ethanol, perfume and additives were dissolved in advance was added thereto and stirred for 30 minutes to prepare a fiber softener composition.
As the additive, a mixture of an aroma solubilizer (5 wt%) and an antifoaming agent (0.05 wt%) was used. As the thickening polymer, an acrylic copolymer (Rheovis FRC of BASF) was used. As the organic acid, citric acid was used.
The edible vinegar is brewed edible vinegar (natural food).
The flower fermented vinegar used was prepared by washing jasmine petals with water, drying, mixing 1 part by weight of edible vinegar and 15 parts by weight of sugar water to the petals with the dried petals, and naturally fermenting for about 7 days.
Comparative example 6
A fabric softener composition having a content (wt%) shown in table 10 below was prepared.
The process for making the fabric softener composition is the same as the above example except that a cationic surfactant is added instead of citric acid.
The cationic surfactant used was polymer LR30M from DOW Chemical.

Experimental example 5: sensory evaluation after washing
Sensory evaluation was performed after washing using the fiber softener compositions prepared by the above examples and comparative examples.
2 pieces of white standard cotton (10X 10cm) specified in KS K0905 were used as clothes to be washed, and LG healthy tech (was used as a laundry detergent)
Trade name).
Washing test conditions according to the test method of EL306 (fiber softener) in the environmental label certification standards of the korean environmental industry technology institute, and the amount of the fiber softener composition used at the last rinsing was 0.67 mL/L.
After the laundry under the above-mentioned washing test conditions was left to stand under constant temperature and humidity conditions of 30 ℃ and 80% relative humidity for 24 hours, 10 panelists performed sensory evaluation on a 5 point scale, in which 1 point represents a case where there was substantially no removal effect on the damp smell, and 5 points represent the most excellent removal effect on the damp smell.
TABLE 11
As shown in table 11 above, the sensory evaluation score for wet odor removal ability was not more than 4 points in the case of using no softener, or using a standard softener, or using a fiber softener composition containing a cationic surfactant, but not preferable, and the sensory evaluation score for wet odor removal ability was not less than 4 points in the case of using a composition containing citric acid and/or flower fermented vinegar, and was excellent.
It was judged that a part of the damp smell could be slightly masked by adding perfume to the composition containing the cationic surfactant.
