Description

  The present invention relates to a fiber softener composition.

  Fiber softeners are widely used at home in order to prevent static electricity generated in clothing and to impart fiber softness, and the amount of use tends to increase gradually. Recently, as consumers' living standards have improved, their desire for hygiene and cleanliness has increased, and as they have pursued a more comfortable clothing life, there has been an increased interest in preventing the growth of microorganisms and the removal of malodors that can occur in clothing. .

  In general, moist smell generated in fibers reacts with volatile organic compounds such as unsaturated lower fatty acids and ammonia produced by decomposition of skin resident bacteria, such as sweat odor components Or can be generated in response to residual ingredients in laundry detergents or fabric softeners. In particular, in the rainy season, since the drying time is delayed during indoor drying, it is known that a moist odor is further generated due to Morxella asloensis which is a malodorous bacterium.

  In order to remove such a moist smell, 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, it has been reported that the use of synthetic antibacterial agents is harmful to the human body, and the use of such antibacterial agents is being avoided.

  Further, after being commercialized worldwide in the 1950s, the fiber softener has used a cationic surfactant as a softening component for more than 60 years, “Korea Published Patent No. 10-2007-0090861”.

  As the pH adjuster, 0.1 to 20% by weight of citric acid among organic acids was used.

  Moreover, the brewery vinegar (natural food) was used for the vinegar.

  The fermented vinegar is made by washing and drying the petals of jasmine, and then mixing 15 parts by weight of vinegar and 15 parts by weight of sugar water with the dried petals with respect to 1 part by weight of the petals. What was obtained was used.

Comparative Example 5
Fabric softener compositions having the compositions and contents shown in Table 8 below were produced.
First, after adding a cationic surfactant to purified water and stirring for 30 minutes, a solution in which ethanol, a fragrance solubilizing agent and an antifoaming agent are dissolved is added thereto, and the mixture is stirred for 30 minutes. Manufactured.

  As the cationic surfactant, TEA Ester Quarter (INCI Name: dihydroxygenated hydroxylhydroxymethosulphate, active 90%) was used.

Experimental Example 4: Measurement of water repellency of Gore-Tex outdoor garment The water repellency of Gore-Tex outdoor garment was measured using the fiber softener compositions of Examples and Comparative Examples.

  The Gore-Tex used in the test was purchased directly from the Gore-Tex garment “ISUKA's GORE-TEX cover” sold in the city, and the laundry detergent used was Tech of LG Living Health.

  The criteria for determining the water repellency are the AATCC (American Textile Chemical Dyeing Association) standards, grade 5 (no adhesion or wetting on the surface), grade 4 (showing little adhesion or wetting on the surface), 3 Grade (indicating wetness at the site where water dropped), Grade 2 (indicating partial wetting over the entire surface), and Grade 1 (in which the surface was completely wetted).

  Table 9 shows the results of measuring the water repellency of the Gore-Tex outdoor clothing.

  As shown in Table 9, in the case of Comparative Example 5 using a cationic surfactant, the cationic surfactant is adsorbed on the Gore-Tex material, reducing the contact angle of water, and the water repellent function In the case of Comparative Example 2 in which the index fiber softener was used, the water repellency was significantly reduced, but in the case of Comparative Example 1 in which only water was used and the cationic surfactant was not used. In Examples 16 to 21, it was confirmed that the water repellent function was not lowered.

Examples 22-26
Fabric softener compositions having the compositions and contents shown in Table 10 below were produced.
First, after adding a thickening polymer to purified water and stirring until complete dissolution, citric acid, vinegar, and flower fermented vinegar are added to this, followed by stirring for 30 minutes, to which ethanol, flavor, and additives are added in advance. The dissolved solution was added and manufactured by stirring for 30 minutes.

  A mixture of a fragrance solubilizer (5% by weight) and an antifoaming agent (0.05% by weight) is used as the additive, and an acrylic copolymer (BASF Rheovis FRC) is used as the thickening polymer. Citric acid was used as the organic acid.

  As the vinegar, brewed vinegar (natural food) was used.

  The flower fermented vinegar was obtained by washing the petals of jasmine with water and drying, then mixing 15 parts by weight of vinegar and 15 parts by weight of sugar water with the dried petals with respect to 1 part by weight of the petals, and undergoing a natural fermentation process for about 7 days. I used something.

Comparative Example 6
A fiber softener composition having the content (% by weight) shown in Table 10 below was produced.
The production process of the fabric softener composition was the same as that of the above example except that a cationic surfactant was added instead of citric acid.

  As the cationic surfactant, Polymer LR30M manufactured by DOW Chemical was used.

Experimental Example 5: Sensory evaluation after washing Sensory evaluation after washing was performed using the fiber softener compositions of the above-described Examples and Comparative Examples.

  Two white standard cotton cloths (10 × 10 cm) specified in KS K 0905 were used as laundry clothes, and the laundry detergent used was Tech of LG Life Health Company.

  The washing experiment conditions were in accordance with the test method in EL306 (fiber softener) among the environmental label certification standards of the Korea Institute of Environmental and Industrial Technology, and the amount of the composition used at the last rinse was 0.67 mL / L.

  Laundry clothes that were developed under the above-described washing experiment conditions were left for 24 hours at a drying temperature of 30 ° C. and a relative humidity of 80%, constant temperature and humidity. A point is a case where there is almost no moist odor removal power, and 5 points | pieces show that it is excellent in the moist odor removal power.

  As shown in Table 11, in the case of a fiber softener composition that does not use a softener, uses an index fiber softener, or contains a cationic surfactant, sensory evaluation of the removal power of a moist odor 4 The composition containing citric acid and / or flower fermented vinegar was excellent with a moist odor removal ability of 4 or more sensory evaluations.

  In the composition containing the cationic surfactant, since the fragrance was used, it was judged that a slightly moist smell was partially masked.
