Description

Liquid detergent composition and liquid detergent containing the same TECHNICAL FIELD [LIQUID DETERGENT COMPOSITION AND LIQUID DETERGENT COMPRISING THE SAME}

The present invention relates to a liquid detergent composition and a liquid detergent in which the liquid detergent composition is packaged with a water-soluble film. More specifically, the present invention provides a liquid detergent composition and a liquid detergent in which the liquid detergent composition is packaged with a water-soluble film, which has improved stability to prevent the packaging and contents from being deteriorated or deformed in the use and storage of the liquid detergent. It is about.

Conventional detergents in powder form have poor storage stability, such as powders scatter and form lumps by absorbing moisture during long-term storage. Recently, the use of liquid laundry detergents is increasing in Korea and around the world. However, in order to properly quantify and use the amount of liquid detergent, it is inconvenient and cumbersome as detergent remains in the measuring container even after the detergent is added by weighing it in the measuring container, and it is difficult to quantify it. Has a drawback. Therefore, the user often does not use the weighing container and immediately puts it in, and in this case, the possibility of using an amount greater than the amount is increased. Using an excess of liquid detergent not only increases the likelihood that residues of the liquid detergent remain even after rinsing, but also increases the cost of washing. To compensate for this, various types of liquid detergents have been developed. For example, concentrated detergents are packaged in a water-soluble film so that users can use concentrated detergents containing 30% or more of the surfactant, which is an active cleaning ingredient, without the need to measure them. There is a liquid detergent.

For example, Korean Patent Registration No. 10-153116 discloses a detergent in which a powder detergent is quantitatively packaged with a film made using polyvinyl alcohol. However, there is a problem in consideration of the fact that the detergent packaged in the film is a powder, and these powder detergents remain in a certain amount between the laundry fibers even after washing is finished, so that when wearing clothes laundry, it is known that it is known that it continuously adversely affects the skin.

Korean Patent Publication No. 2004-67668 discloses a liquid detergent packaged with a water-soluble film and a method for manufacturing the same. In this document, since the liquid detergent packaged in the film has a water content of 7% or more of the liquid detergent packaged in the water-soluble film, there is a problem that the water-soluble film packaging may be dissolved during storage.

In this way, the liquid detergent packaged in a water-soluble film unit is convenient to use, but when it comes into contact with moisture during storage, the packaging may dissolve, and when exposed to air for a long time, its appearance may be deformed and its contents may deteriorate, resulting in poor performance There are drawbacks. The cause of this phenomenon is that the amount of water in the liquid detergent composition is low in order to prevent the mutual reaction between the water-soluble film constituting the unit packaged liquid detergent and the liquid detergent composition, and even the water contained in it is a surfactant that helps its evaporation. It plays a role, altering the nature of the contents, which is believed to lead to deformation of the entire package.

Accordingly, there is a need to develop a liquid detergent composition that maintains cleaning power while delaying the evaporation of moisture in the liquid detergent composition, or by diversifying the packaging capsule shape of the water-soluble film to increase the stability of the water-soluble film and the liquid detergent composition.

In the case of products that must exhibit detergency, ionic surfactants, especially anionic surfactants, are known to have excellent detergency, and if two or more mixtures are used than a single anionic surfactant, synergistic effect in detergency is achieved. As can be seen, it is preferable to use a mixture of a sulfonate-based anionic surfactant and a sulfate-based anionic surfactant.

Preferred sulfonate-based anionic surfactants include alkylbenzene sulfonates, olefin sulfonates, secondary alkane sulfonates, alpha sulfonate methyl/ethyl esters, or these, wherein the alkyl group is a linear or branched alkyl having 9 to 18 carbon atoms.

A preferred sulfate-based anionic surfactant may be an alkyl ether sulfonate represented by the following formula (1),

In the formula of Formula 1,

R ₁ is an alkyl group having 8 to 16 carbon atoms, preferably an alkyl group having 10 to 16 carbon atoms, more preferably an alkyl group having 12 to 14 carbon atoms,

M is a cationic salt, preferably sodium, potassium, ammonium or alkanol ammonium, more preferably sodium,

The anionic surfactant is preferably contained in an amount of 0.1 to 40% by weight, more preferably 5 to 30% by weight based on the liquid detergent composition. When the content of anionic surfactant is less than 0.1% by weight, there is a problem that the cleaning power and foaming power are deteriorated, and when it exceeds 40% by weight, the cleaning power according to the content does not increase in a simple proportion, so it is not economical. have.

The nonionic surfactant, which is a component of the liquid detergent composition of the present invention, may be those commonly used in the field. Preferred nonionic surfactants include primary or secondary alcohol-based nonionic surfactants having a linear or branched alkyl or alkenyl group having 8 to 22 carbon atoms containing 1 to 25 moles of ethylene oxide, and a straight chain having 8 to 22 carbon atoms. Alternatively, an alkyl polyglycoside nonionic surfactant having a branched alkyl or alkenyl group may be used. In addition, as a fatty acid amide-based nonionic surfactant, a fatty acid amide system having a linear or branched alkyl or alkenyl group having 8 to 22 carbon atoms, and a fatty acid amide in the form of ammonia amide, monoethanol amide, diethanolamide or isopropanolamide Nonionic surfactants can be used.

The nonionic surfactant is preferably contained in an amount of 1 to 60% by weight, more preferably 10 to 40% by weight, based on the liquid detergent composition. If the nonionic surfactant is contained in less than 1% by weight, there is a problem that the cleaning power is lowered, and if it exceeds 60% by weight, surfactant monomers form a combination to form micelles, forming an appropriate structure. Problems may arise that may act adversely.

The liquid detergent composition of the present invention includes an electrolyte, and in the composition including a surfactant, the electrolyte exhibits a gradual effect and exhibits various effects, such as enhancing dispersion stability of effective particles and air bubbles.

As the electrolyte, chloride, bromide, iodide, acetate, bicarbonate, phosphate, citrate, sulfate, polyphosphate, pyrophosphate, triphosphate, tetraphosphate, silicate, metasilicate as a salt of a monovalent or polyvalent organic or inorganic acid. , Polysilicate, carbonate, hydroxide, alkali metal salt or mixtures thereof may be used.

The electrolyte content is preferably 0.1 to 10% by weight based on the liquid detergent composition, and more preferably 0.5 to 5% by weight. When the content of the electrolyte is less than 0.1% by weight, the effect of the electrolyte is insignificant because the increasing effect and dispersion stability are lowered, and when the content of the electrolyte is more than 10% by weight, there is a problem that salts of the electrolyte may interfere with the structuring of surfactants.

As a component constituting the liquid detergent compositions of the present invention, the solubilizing agent plays a role of maintaining the surfactant in a stable state, and preferable solubilizing agents include glycerin, propylene glycol, alkanols having 1 to 4 carbon atoms, and alkylaryl sulfonates. , Carboxylic acid sulfate, carboxylic acid sulfonate salt, urea, hydrocarboxylate, carboxylate or mixtures thereof may be used.

The solubilizing agent is used in an amount of 5 to 40% by weight, more preferably 10 to 30% by weight, based on the liquid detergent composition, and if it is less than 5% by weight, the solubilization effect is not sufficiently exhibited, and if it exceeds 40% by weight There is a fear that the viscosity will be very low.

In order to prevent the evaporation of moisture in the liquid detergent composition, the liquid detergent composition of the present invention may contain a swellable polymer capable of forming ultrafine fibers or having a plurality of hydroxy groups capable of trapping moisture. The liquid detergent composition may delay evaporation of moisture due to a difference in evaporation partial pressure between the atmospheres. The swellable polymer may be one that acts as a builder.

Preferred swellable polymers are polyethylene oxide polymers, poly(vinyl alcohol) polymers, polyethylene glycol polymers, polyacrylamide polymers, and poly(acrylamide) polymers. )) Polymer, poly(acrylic acid) polymer, polyacrylate polymer, Carbopol polymer, poly(acrylic acid-co-acrylamide) Polymer, poly(acrylic acid-co-maleic acid) polymer, polyacrylic acid-graft-poly(ethylene oxide) polymer, polyethylene-co- Acrylic acid (poly (ethylene-co-acrylic acid) polymer, starch, cellulose, ethylene maleic copolymer, or a mixture thereof may be used.

The swellable polymers preferably have a molecular weight of 100 to 1000 or less, and more preferably 200 to 800 or less. If the molecular weight is less than 100, the effect of trapping moisture may be insignificant, and if the molecular weight exceeds 1000, there is a problem in that it may hinder the structuring of the liquid detergent composition while hindering dissolution of other components.

In addition, the content of the swellable polymer is preferably 5 to 30% by weight. More preferably, it may be 10 to 25% by weight. When the content of the swellable polymer is less than 5% by weight, it is insufficient to cause a difference in water evaporation partial pressure with the atmosphere, and when it is more than 30% by weight, the viscosity of the liquid detergent composition may be excessively increased.

The liquid detergent composition of the present invention is an organic solvent, detergent adjuvant, stabilizer, enzyme, preservative, fragrance, dye, viscosity modifier, chitosan, in addition to the above-described components, within the scope not impairing the object of the present invention. It may further include one or more additives selected from the group consisting of a metal ion sealant and a pH adjuster.

The preservative may be ethanol, phenoxy ethanol, benzisothiazolinone, methylchloroisothiazolinone, methylisothiazolinone, pentindiol, parabens, sodium benzoate, and the like, but is not limited thereto.

The pH adjusting agent is excellent in removing oil stains, and any low molecular weight organic or arbitrary organic compound that provides neutrality is possible. Preferably, monoethanolamine, diethanolamine, triethanolamine, sodium hydroxide, potassium hydroxide liquid alkali and citric acid, malic acid, salicylic acid, tartaric acid, lactic acid, acetic acid, sorbic acid, benzoic acid and the like are possible.

The metal ion encapsulant can be used to increase the formulation and phase stability of the liquid composition of the present invention, EDTA, EDTA-2Na, EDTA-4Na, DTA, NTPA, phosphates, polyacrylic acid, gluconic acid, sorbate, One or more selected from the group consisting of sodium bicarbonate and the like can be used.

In addition, the enzyme is used to further increase the cleaning effect of the liquid detergent composition, mainly alkaline proteolytic enzymes may be used, and specifically, may be used by selecting from the group consisting of proteases, lipases, amylases, and mixtures thereof. The content of the enzyme is preferably 0.1 to 1% by weight, which is a typical range of the enzyme based on the total composition.

The present invention also provides a liquid detergent comprising all of the liquid detergent compositions described above as a liquid detergent composition and a water-soluble film surrounding the liquid detergent composition.

As a packaging material for the liquid detergent composition, a water-soluble film that can be quickly and completely dissolved in water at a temperature of 0° C. or higher, and the material itself is strong and flexible, and has no stickiness in storage conditions at high temperature or low temperature, high humidity, or dry, is preferable. Specifically, polyvinyl alcohol, polyethylene oxide, methyl cellulose, etc. are mentioned.

The thickness of the water-soluble film is preferably 10 to 100 μm in consideration of storage stability of the liquid detergent composition and solubility in water during washing. If the thickness of the water-soluble film is less than 10 μm, it may be dissolved due to water in the liquid detergent composition during storage, so that storage stability is lowered, and if it exceeds 100 μm, degradability in water during washing is lowered, which is not preferable.

Since the water-soluble film is dispersed in water at a water temperature of 0 ℃ or higher and has a property of being completely dissolved at 2 to 5 ℃, it can be applied in either low or high temperature. When sealing a liquid detergent composition with a water-soluble film, the relative moisture content of the film There are some differences depending on the case, but it is easily sealed by heating at about 150 to 200°C for about 0.5 seconds.

The water-soluble film exhibits excellent storage stability against vegetable oils, mineral oils, etc., and exhibits very excellent storage stability against fats, organic solvents, hydrocarbons, etc., and also nitrogen, oxygen, dioxide, etc. It exhibits excellent storage stability even for the same gas and allows moisture in the air to penetrate, so the film itself has excellent storage stability. In addition, it is preferable that the water-soluble film is completely dissolved in carbon dioxide and water under certain conditions to have biodegradable properties.

Therefore, from the viewpoint of stability against moisture and humidity of the film used in the present invention, it is preferable to manufacture it so that a little moisture is included for the stability of the film itself in the film manufacturing process, and the content of this moisture is In order to contain only moisture, when the film itself contains less than a certain amount of moisture, it absorbs moisture in the air, and when it contains more than a certain amount, it has the characteristic of dissipating the moisture of the film itself. It is desirable to manufacture to have properties that can be minimized. Experimental Results When the water-soluble film of the present invention has a relative humidity of 45, 65, and 80%, the average moisture content after 72 hours at 20°C is 5 to 7%, 8 to 10%, and 12 to 15%, respectively. And exhibited stable properties within this range of moisture content.

It is preferable to use the liquid detergent packaged in the water-soluble film of the present invention individually packaged and packaged in an amount required for normal one-time washing. Therefore, since it is possible to use only an appropriate amount when washing, it is economical because overuse of detergent can be prevented, and it is convenient to use because it can be administered directly to the washing tank together with the laundry during washing, and storage stability and transportability are also excellent.

The water-soluble film packaging form in which the present invention can be used is preferably a capsule form forming one space, a capsule form forming two or more spaces in two or more fractions, or a double film form having one or more independent capsules within the capsule. For example, the capsule form forming one space may be formed by sealing the edge of the water-soluble film into a capsule shape, and the capsule form forming two or more spaces in two or more fractions is in addition to sealing the edge of the water-soluble film, the capsule It can be formed by sealing so that the inside can be fractionated. As another example, a method of independently forming a plurality of pockets and then attaching them may be used, and a method of independently forming pockets of different sizes and then encapsulating one side to contain the other may be used.

It is preferable that the water-soluble film constituting each capsule in the water-soluble film in the form of two or more fractionated capsules according to one embodiment of the liquid detergent of the present invention or in the form of a double film having one or more capsules in the capsule has different reception delay times And, it is preferable that the liquid detergent composition in each capsule has different components and compositions. This encapsulates the composition required at the beginning of washing and the composition useful at the end of washing, respectively, in capsules having different reception delay times, so that the compositions playing different roles are released at different times, thereby enabling efficient washing without interfering with each other. You can make it possible.

It is preferable that the water-soluble film having different delay times contains, for example, a water-insoluble cellulose polymer. Cellulosic polymers are high molecular weight polymers having repeating units of a basic sugar structure, and hydroxyl groups on the polymer are derivatized so that they can play various roles.In particular, a cellulose polymer formed by capping several hydroxyl groups on the cellulose polymer with methyl or ethyl , Can reduce the level of hydrogen bonding and somewhat reduce the hydrophilicity of the polymer. Therefore, in order to increase the reception delay time of the water-soluble film, such a water-insoluble component may be appropriately contained, and the molecular weight and degree of substitution of the contained water-insoluble polymer may affect the reception delay time of the water-soluble film.

In addition, in the case of a liquid detergent having a water-soluble film in the form of a double film having one or more capsules in the capsule, it is divided into an outer capsule and an inner capsule, and the space between these capsules is relatively high in contact with moisture and air among liquid detergent compositions. By including stable substances, even if the liquid detergent is used and stored for a long period of time, problems caused by moisture evaporation or contact with air or moisture of the conventional liquid detergent can be resolved.

Hereinafter, the present invention will be described in more detail through examples, but the following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

2. Evaluation of cleaning power

To evaluate the cleaning power of the liquid detergent, a stirring mixed cleaning power tester for laboratory use (Terg-o-tometer) was used. The washing power measurement temperature was operated at 20° C. at a rotation speed of 100, and the sample amount was 1 liter of water and 1 g of sample was used, the washing time was 10 minutes, and the rinsing was performed twice for 3 minutes each. The artificial contaminant cloth used for the measurement was a wet artificial contaminant from the Japan Laundry Science Association. Wet artificial soiling cloth was 5cm X 5cm in size and 8 sheets per sample were used. The washing effect for each contaminated cloth before and after washing was measured using a color difference meter (Nippon denshoku) and compared using Equation 1 below. For the comparative detergent, a standard liquid detergent of Korean industrial standard synthetic detergent was used, and compared with this, if the washing power was superior, it was marked as good, and if the washing power was not superior, it was marked as bad.

3. Results of stability and cleaning power evaluation

Table 2 below is a comparison of Examples 1 to 3 and Comparative Examples 1 and 2 by checking the aging stability for 16 weeks.

Storage at 25℃ Good Good Good Film part hardens and becomes cloudy from 6th week From the 10th week, the film in the contents is softened and the contents leak. Cleaning power Good Good Good Good Good

According to Table 2, in evaluating the cleaning power, both Examples 1 to 3 and Comparative Examples 1 and 2 showed superior cleaning power compared to the cleaning power of the standard liquid detergent. However, the compositions of Examples 1 to 3 prepared using polyethylene glycol showed a good state because the film was hardened and became opaque or leaking of the contents was not observed when the change in appearance was observed. In the case of Comparative Example 1 and Comparative Example 2, the film became opaque by curing at the 6th week, and from the 10th week, the water-soluble film portion directly in contact with the contents softened and the contents leaked. It can be seen that when the compositions of Examples 1 to 3 according to the present invention are packaged with a water-soluble film, they exhibit excellent stability in long-term use and storage.
