Description

Liquid detergent composition for vapor-permeable and water-repellent functional fabrics

The present invention relates to a liquid detergent composition for moisture-permeable and water-repellent functional material, and more particularly, to maintain the water-repellent and water-repellent function of clothing despite repeated washings because of excellent washing power and rinsing property for contaminants attached to synthetic fibers. A liquid detergent composition for moisture permeable and water repellent functional materials.

Recently, with the development of science and technology, clothing materials having various functions have been continuously developed. Among these functional materials, moisture-permeable and water-repellent materials are processed into a high-density fabric using ultra-fine fibers, or a fine porous membrane is laminated to the fabric so that external water droplets are water-repellent from the clothing surface before penetrating into the interior, and internal moisture is discharged. to be. Since internal moisture is discharged, wear is increasing in sports and leisure fields to maintain homeostasis of the human body.

Moisture-permeable and water-repellent material clothing has a problem that the micropores inside the fiber is blocked by repeated wearing is reduced its function. In order to solve such a problem, a high rinsing power for sebum contamination in human secretions and at the same time a fast rinsing property in which no cleaning ingredients remain in the garment is required. However, there is still little research on detergent compositions suitable for moisture-permeable and water-repellent garments.

JP-A 2001-40392 discloses high detergency for sebum contamination of the sleeve and neck by specific alkoxy compounds having two hydroxy groups and polyoxyalkylenealkylether added with ethylene oxide. However, the liquid detergent may not be suitable for clothing of moisture-permeable and water-repellent material because it is not rinsable.

In addition, in the case of liquid detergent, the detergent composition is uneven due to the occurrence of phase separation or the like, and there is a disadvantage of causing precipitation or flotation of insoluble contents.

In order to solve the above problems, an object of the present invention is to provide high cleaning power against sebum contamination generated while wearing clothes, and at the same time, excellent rinsing properties to prevent the cleaning components from remaining in the clothes, It is to provide a liquid detergent composition for moisture-permeable and water-repellent functional material to maintain the moisture-permeable and water-repellent function so as not to lose the original function.

According to an aspect of the present invention,

10 to 40 parts by weight of a nonionic surfactant having a HLB (Hydrophilic Lipophilic Balance) value of 9 to 11 based on 100 parts by weight of the total composition;

0.5 to 10 parts by weight of alkylene glycol, based on 100 parts by weight of the total composition; And

It provides a liquid detergent composition for moisture-permeable and water repellent functional material comprising 0.5 to 5 parts by weight of fatty acid salt with respect to 100 parts by weight of the total composition.

The nonionic surfactant may be represented by Formula 1 below:

<Formula 1>

RO- (EO) x- (PO) y-H

(In Chemical Formula 1,

R is a linear or branched alkyl or alkenyl group having 6 to 16 carbon atoms,

EO is an oxyethylene group,

PO is an oxypropylene group,

x represents the average added mole number of ethylene oxide, It is 3-14,

y represents the average added mole number of propylene oxide, and is 1-5,

(EO) x and (PO) y are block-bonded or random-bound in any order.)

The alkylene glycol can be a single or a mixture thereof selected from ethylene glycol, propylene glycol and butylene glycol.

The fatty acid salt may be an alkali metal or alkanol amine salt of saturated or unsaturated fatty acids having 12 to 18 carbon atoms.

The liquid detergent composition of the present invention is suitable for washing the moisture-permeable and water-repellent functional material with high cleaning power against sebum contamination adhered to the fiber and fast rinsing of the cleaning component upon rinsing. Therefore, it is possible to prevent shortening of the life due to repeated washing of the moisture-permeable and water-repellent functional clothing.

In addition, it is easy to weigh when used as a liquid detergent type, has the advantage that the dust does not fly compared to the powder detergent, it can also be used directly applied to a specific area with high pollution. Powdered detergents also compensate for the disadvantages of lumps that can occur during long-term storage.

The liquid detergent composition of the present invention is excellent in phase stability and does not phase separate even if stored for a long period of time, and less precipitates and floats are generated.

Hereinafter, the present invention will be described in detail.

The moisture-permeable and water-repellent functional material liquid detergent composition of the present invention includes a nonionic surfactant having a Hyclohilic Lipophilic Balance (HLB) value of 9 to 11. The nonionic surfactant having a HLB value of 9 to 11 improves the stability of the composition and improves the cleaning power, thereby removing sebum contaminants adhered to the moisture-permeable and water-repellent functional material.

The HLB value is a value indicating the degree of hydrophilicity or lipophilicity of a surfactant. Larger HLB values indicate increased hydrophilicity. It is preferable that the HLB value of the said nonionic surfactant of this invention is 9-11. If it is less than 9 low temperature storage stability is lowered, if the HLB value is greater than 11 rinsing property may be lowered.

The nonionic surfactant may be included in an amount of 10 to 40 parts by weight based on 100 parts by weight of the total composition. If less than 10 parts by weight of the cleaning power is reduced to remove the sebum, etc. stuck to the pores of the water-repellent water-repellent material clothing can reduce the moisture permeability of the moisture-repellent and water-repellent functional material, if added in excess of 40 parts by weight It may be degraded and phase separation may occur during long-term storage, and there may be a problem of low commerciality due to high cost.

The nonionic surfactant may be represented by Formula 1 below:

<Formula 1>

RO- (EO) x- (PO) y-H

(In Chemical Formula 1,

R is a linear or branched alkyl or alkenyl group having 6 to 16 carbon atoms,

EO is an oxyethylene group,

PO is an oxypropylene group,

x represents the average added mole number of ethylene oxide and is 3-14,

y represents the average added mole number of propylene oxide and is a number from 1 to 5,

(EO) x and (PO) y are block-bonded or random-bonded in any order.)

The nonionic surfactant represented by Chemical Formula 1 has a washing power sufficient to remove sebum attached to clothes while being hypoallergenic to the skin in the form of ethylene oxide and propylene oxide added.

The addition method of ethylene oxide and propylene oxide may be added in a random form, ethylene oxide may be added and propylene oxide may be added, or vice versa.

The liquid detergent composition of the present invention comprises alkylene glycol. The alkylene glycol acts as a cleaning aid to increase the cleaning power against sebum contamination when used simultaneously with the nonionic surfactant, and to increase the rinsability of the nonionic surfactant to increase the rinsability of sebum contamination during repeated washing of the moisture-permeable and water-repellent functional material. Residual components of the detergent prevent the reduction in water repellency.

The alkylene glycol is preferably included in 0.5 to 10 parts by weight based on 100 parts by weight of the total composition. When included in less than 0.5 parts by weight, the effect of increasing the cleaning and rinsing power is insignificant to reduce the water repellency of the moisture-permeable and water-repellent functional material garments, the liquid detergent composition is unstable when added in excess of 10 parts by weight.

The alkylene glycol may be used alone or a mixture thereof selected from the group consisting of ethylene glycol, propylene glycol and butylene glycol. Preferably, ethylene glycol or propylene glycol may be used.

The liquid detergent composition of the present invention comprises a fatty acid salt. Since the fatty acid salt is used in conjunction with the non-ionic surfactant to reduce the amount of bubbles generated to improve the rinsing property, the cleaning component can be prevented from remaining in the garment to reduce its function during repeated washing of the moisture-permeable and water-repellent functional clothing.

The fatty acid salt may be an alkali metal or alkanol amine salt of a saturated or unsaturated fatty acid having 12 to 18 carbon atoms.

The fatty acid salt is a form in which saturated or unsaturated fatty acids having 12 to 18 carbon atoms are neutralized with an alkali metal or alkanol amine. Examples of the alkali metal include sodium and potassium, and examples of the alkanol amine include monoethanolamine, diethanolamine, and triethanolamine. In order to improve the low temperature storage stability of the composition, it is preferable to use a form of potassium salt or alkanol amine salt.

The fatty acid salt may be included in an amount of 0.5 to 5 parts by weight, preferably 0.5 to 3 parts by weight, based on 100 parts by weight of the total composition. If the amount is less than 0.5 parts by weight, the effect of increasing the rinsing property is insignificant, and when added in excess of 5 parts by weight, the stability of the composition may be lowered.

The liquid detergent composition of the present invention includes an additive which is a single or mixture thereof selected from the group consisting of preservatives, chelating agents, flavoring agents, antifoaming agents and dyes as necessary.

The additive may be included in an amount of 0.01 to 10 parts by weight, preferably 0.01 to 5 parts by weight, more preferably 0.01 to 1 part by weight, based on 100 parts by weight of the total composition. The content may vary depending on the object, purpose and cleaning method of the object to be cleaned. The additives may be contained within a range in which washing power and rinsing property against sebum contamination adhered to synthetic fibers or human and environmental stability and storage stability are not impaired.

The liquid detergent composition of the present invention includes water as the remaining components in addition to the above components.

The liquid detergent composition of the present invention is prepared by mixing the above components by conventional methods known in the art. When the liquid detergent composition prepared in this way is used for washing moisture-permeable and water-repellent functional materials, high cleaning power and fast rinsing function against sebum contamination adhered to the synthetic fiber by nonionic surfactants, glycols and fatty acid salts can be simultaneously exhibited. It is possible to maintain the original function of the moisture-permeable and water-repellent functional material despite repeated washing.
