Description

The present invention relates to a solid detergent having excellent environmental friendliness, disintegration property and detergency.

Surfactants have hydrophobic and hydrophilic groups that can reduce the interfacial tension of liquids, so they mix well with both oil and water to make soaps, synthetic detergents, or cosmetics. It is contained as an essential ingredient in. Surfactants include natural surfactants and synthetic surfactants, and synthetic surfactants have the advantages of low price and strong detergency, so most of them in daily life. Uses synthetic surfactants in.

However, synthetic surfactants weaken not only pollutants but also skin lipids with strong detergency to reduce the skin barrier function. Therefore, foreign matter easily permeates into the skin, water in the skin is easily evaporated, and xeroderma and wrinkle formation are promoted, so that aging can proceed rapidly.

In addition, it has been raised as a causative substance that induces various skin allergies, dermatitis, etc. Builders, preservatives, artificial fragrances, etc. added to enhance the function of detergents made using synthetic surfactants Since its stability has not been verified, it is susceptible to potential hazards. That is, products containing synthetic surfactants only focus on the function of removing pollutants, and do not consider the aspects of skin health and environmental protection at all.

Recently, in order to improve the disadvantages of synthetic surfactants, products containing natural surfactants have been demanded and developed. However, natural surfactants are difficult to store because they are greatly affected by the external environment, are more expensive than synthetic surfactants, and have less foam, which may make it difficult to stimulate the purchasing power of users. ..

On the other hand, kitchen cleaners are generally used in liquid form, but kitchen liquid cleaners are not easy to carry and store due to their heavy and heavy feel. In addition, such a liquid cleaning agent for kitchen is generally administered to a cleaning instrument or a cleaning object at a time prior to a full-scale cleaning operation, and a large amount of the cleaning agents added at this time is used. There is a problem that the part is exhausted in the early stage of the cleaning work and it is difficult to maintain the cleaning power in the entire section of the cleaning work. A cleaning agent will be used. Therefore, it is disadvantageous in terms of economic efficiency and environmental friendliness.

In addition, since kitchen cleaners come into direct contact with the user's skin during use, they remain on the skin after use and induce skin diseases, and if they remain on the dishes, such detergent components are used by the user. Directly administered orally, it may adversely affect health and hygiene.

Along with this, we have developed a solid type kitchen cleaner, but in the case of the solid type, it is exposed to the external environment until it is consumed after use, so bacterial growth can be facilitated and hygienic management is difficult. is there. Also, the use may reduce the size of solid-type kitchen cleaners, which can be inconvenient for users in the process of foaming.

Therefore, there is a demand for the development of a solid detergent containing a natural surfactant and having excellent environmental friendliness, but with improved destructiveness and detergency.

The present invention is for solving the above-mentioned problems of the prior art, and an object of the present invention is to provide a solid detergent having excellent environmental friendliness but improved destructiveness and detergency. It is in.

One embodiment of the present invention is a solid in which a mixture containing 20-40% by weight of sodium lauryl sulfoacetate powder; 50-70% by weight of sugar powder; and 1-10% by weight of sodium hydrogen carbonate powder; is tableted into a tablet form. Provide cleaning agent.

In one example, the water content of the mixture can be 6% by weight or less.

In one example, the sugar powder can include glucose powder.

In one example, the sugar powder can further comprise sucrose powder.

In one example, the content of the sucrose powder in the sugar powder can be 20-80% by weight.

In one example, the sucrose powder can be porous particles.

In one example, the porosity of the porous particles can be 20-80% by volume.

In one example, the apparent density of the mixture may be 0.5-1.5 g / cc and the apparent density of the solid detergent may be 1.51-3.0 g / cc.

In one example, the solid detergent may have a diameter of 7-30 mm.

The solid detergent according to one aspect of the present invention contains sugar powder in a natural surfactant, and can enhance environmental affinity and detergency. In particular, since the mixture mixed in the powder state can be tableted in the form of tablets without a binder, it is easy to disintegrate and generate bubbles during washing, and the washing power can be improved.

In addition, the solid detergent is tableted in the form of tablets and is easy to store, and can prevent excessive use as compared with the liquid type detergent, so that environmental protection and economic effects can be realized. Can be done.

It should be understood that the effects of the present invention are not limited to the above-mentioned effects, but include all effects that can be inferred from the structure of the invention described in the detailed description or claims of the present invention.

It is a particle size distribution curve of sodium lauryl sulfoacetate powder according to one Example of this invention. It is a particle size distribution curve of dextrose powder according to one Example of this invention. It is a particle size distribution curve of sodium hydrogen carbonate powder according to one Example of this invention. It is a measurement result of the apparent density of the powder mixture by one Example of this invention. It is a measurement result of the apparent density of the solid detergent by one Example of this invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be embodied in a variety of different forms and is therefore not limited to the embodiments described herein.

Also, in the entire specification, when any part "contains" a component, this does not exclude other components unless otherwise stated, and further includes other components. It means that it can be equipped.

One embodiment of the present invention is a solid in which a mixture containing 20-40% by weight of sodium lauryl sulfoacetate powder; 50-70% by weight of sugar powder; and 1-10% by weight of sodium hydrogen carbonate powder; is tableted into a tablet form. Provide cleaning agent.

In general, the cleaning agent contains a surfactant and can play a role of removing oil stains by dissolving in water. An interface means a interface where a gas and a liquid, a liquid and a liquid, and a liquid and a solid touch each other, but a surfactant has a hydrophilic group on one side of the molecule and a hydrophobic group on the other side. Since they are present at the same time, they can play a role of reducing the surface tension of the interface and, accordingly, relaxing the boundary of the interface.

When the concentration of surfactant molecules exceeds a certain level during washing, micelles, which are aggregates of hydrophobic groups on the inside and hydrophilic groups on the outside, can be formed. The hydrophobic groups aggregated in the micelles can draw oil stains contaminated on the object to be washed into the micelles, and the oil stains can be removed by water during rinsing.

Conventional cleaning agents include synthetic surfactants, which are inexpensive and have excellent detergency, but are typically sodium lauryl sulfate, sodium laureth sulfate, and ammonium lauryl sulfate (sodium laureth sulfate). Sulfate systems such as Aluminum Lauryl Sulfate) and Ammonium Laureth Sulfate are widely used.

Sulfate-based surfactants are inexpensive, are not significantly affected by the external environment, and have excellent detergency. However, when sulfate-based products are used for a long period of time, they may be transformed into 1,4-dioxins in the body and accumulated as carcinogens, which may cause various skin diseases and dysfunctions.

Therefore, the solid detergent contains a natural surfactant, realizes environmental friendliness and skin protection effect, and contains sugar powder and sodium hydrogen carbonate powder, and can improve the detergency.

The solid detergent can include sodium lauryl sulfoacetate powder. The sodium lauryl sulfoacetate is an anionic natural surfactant derived from coconut, which has less skin irritation, abundant bubbles, and excellent detergency. Therefore, it is a bubble bath salt and shampoo. , Used for cleansing products, etc.

In particular, the skin deep score (Skin Deep Score) according to the EWG grade is evaluated as 1, and the skin stability is very excellent. In addition, it can maintain a stable dosage form when blended with other surfactants, and can be applied to various products.

As used herein, the term "EWG grade" is a cosmetic ingredient hazard grade published by the US non-profit environmental citizen group EWG (Environmental Working Group), and in particular, EWG is a cosmetic ingredient hazard. In-depth investigation of sex is carried out, and the degree of toxicity of ingredients is classified from 1st grade to 10th grade, and 1st grade and 2nd grade are classified into safety grades.

On the other hand, the content of the sodium lauryl sulfoacetate powder can be 20 to 40% by weight based on the total weight of the solid detergent. If the content of the sodium lauryl sulfoacetate powder is less than 20% by weight, the detergency may be lowered, and if it is more than 40% by weight, the moisturizing power may be lowered.

The solid detergent can include sugar powder. The sugar powder may be at least one selected from monosaccharides, disaccharides and combinations thereof, preferably glucose powder, and more preferably dextrose (dextrose). It may be glucose) powder.

The monosaccharide is a basic unit of a carbohydrate composed of one sugar that is not further hydrolyzed by an acid, a base, an enzyme or the like, is a colorless crystal, is water-soluble, and is insoluble in ether and ethanol. The types of the monosaccharides are classified according to the number of carbon atoms. The most abundant monosaccharides in the natural state are hexacarbonate sugars, and the types include glucose, fructose, and galactose.

The disaccharide is a combination of two monosaccharides, and the types thereof include sucrose, maltose, and lactose. The mixture thereof, that is, a polysaccharide, is a form formed when energy is stored or a structure is formed in an animal or a plant, and many monosaccharides can be formed by binding. The polysaccharides can be divided into digestible starch and glycogen and indigestible cellulose.

The content of the sugar powder can be 50 to 70% by weight based on the total weight of the solid detergent. If the content of the sugar powder is less than 50% by weight, the detergency may be lowered, and if it is more than 70% by weight, it is contained more than necessary and no further effect can be realized.

On the other hand, the sugar powder can be dissolved in water at the time of washing, and sugar molecules can attach and remove contaminants to realize a synergistic effect with the sodium lauryl sulfoacetate and maximize the washing power. Further, since the sugar powder can be decomposed by microorganisms after washing, it has excellent environmental affinity and can realize the skin protection effect of the user. Since the sugar powder is highly soluble and reactive when it is a monosaccharide, the sugar powder can be a monosaccharide, preferably a glucose powder.

The glucose is produced by hydrolyzing corn starch with heat, acid, and enzyme, and is generally known as glucose, and exists in the form of a six-membered ring having an aldehyde group. There are two types of optical isomers of glucose, D-type and L-type, but in the natural state, D-glucose is the majority, L-glucose does not exist in the natural state, and the production method is Due to its high complexity, manufacturing costs can increase when L-glucose is applied to cleaning agents. Therefore, the sugar powder can be a D-glucose powder, i.e. a dextrose powder.

The solid detergent may include sodium bicarbonate powder. The sodium hydrogen carbonate can adjust the pH of the solid detergent in the range of 7.0 to 8.0 to prevent recontamination of the object to be cleaned, and at the same time, can realize the skin protective effect of the user. Detergency can be improved with sodium lauryl sulfoacetate and the sugar powder. Further, the sodium hydrogen carbonate absorbs water contained in another powder, for example, a sugar powder in the process of mixing and tableting the powder for producing the solid detergent, and binds them to each other. Thereby, the structural and morphological stability of the solid detergent can be improved, and the required level of gloss can be imparted to the cleaning object to provide a visual satisfaction to the user.

The content of the sodium hydrogen carbonate can be 1 to 10% by weight based on the total weight of the solid detergent. If the content of the sodium hydrogen carbonate is less than 1% by weight, the detergency may be reduced, and if it is more than 10% by weight, the skin of the user may be damaged.

As the solid detergent, a mixture containing sodium lauryl sulfoacetate powder, sugar powder, and sodium hydrogen carbonate powder can be tableted in the form of tablets, and the water content of the mixture is 6% by weight or less, preferably more than 0% by weight. It can be 6% by weight or less. The term "moisture content" used herein is a percentage of the weight of water relative to the total weight of a particular substance containing water. For example, the water content of a water-containing mixture means the percentage of the weight of water to the total weight of the mixture. The form having a water content of 0% by weight is not included in the present invention.

If the water content of the mixture is more than 6% by weight, the processability of the mixture and the structural and morphological stability of the solid detergent may be deteriorated, and the mixture is substantially free of water. In the case, the mixture is less likely to be tableted by a solid detergent having a certain form due to friction between the powders.

Conventionally, in the case of a solid detergent, a binder for improving the binding force between powders has been used separately, but such a binder reduces the disintegration property of the solid detergent and is essentially water-insoluble. Therefore, even if only a small amount is used, the detergency may be reduced, which is disadvantageous in terms of environmental friendliness.

The powder constituting the solid detergent, for example, sugar powder, can contain a certain amount of water, and the water content of the solid detergent can be adjusted to a certain range accordingly. As described above, the sodium hydrogen carbonate powder absorbs the water in the process of mixing and tableting the powder for producing the solid detergent, and binds them to each other to obtain the solid detergent. Structural and morphological stability can be improved.

1 to 3 are particle size distribution curves of sodium lauryl sulfoacetate powder, dextrose powder, and sodium hydrogen carbonate powder according to an embodiment of the present invention, respectively.

The particle size of each powder, along with the water content, is an important factor in the processing of the powder, that is, tableting. If the particle size of the powder is excessively large, the rate of disintegration may be reduced, and the generation of bubbles and the detergency may be reduced. The sex may be reduced.

Referring to FIG. 1, the average particle size of the sodium lauryl sulfoacetate powder can be 40-80 μm. If the average particle size of the sodium lauryl sulfoacetate powder is less than 40 μm, the processability may be lowered, and if it is more than 80 μm, the disintegration property and the detergency may be lowered.

With reference to FIG. 2, the average particle size of the glucose powder can be 70-130 μm. If the average particle size of the glucose powder is less than 70 μm, the processability may be lowered, and if it is more than 130 μm, the disintegration property and detergency may be lowered.

Referring to FIG. 3, the average particle size of the sodium hydrogen carbonate powder can be 60-120 μm. If the average particle size of the sodium hydrogen carbonate powder is less than 60 μm, the processability may be lowered, and if it is more than 120 μm, the disintegration property and the detergency may be lowered.

On the other hand, the sugar powder can further contain sucrose powder. The sucrose is a combination of glucose and fructose, and is also referred to as sucrose or sugar. The sucrose is a natural sweetener made by refining raw sugar obtained from sugar cane or sugar beet. Specifically, liquid sugar can be extracted from sugar cane trunks or sugar beet roots, and the sugar solution can be boiled and filtered to eliminate impurities, and crystallized for production.

Since the sucrose powder has substantially the same action and effect as the dextrose powder, a part of the sucrose powder, for example, 20% by weight or more, preferably 50% by weight or more of the dextrose powder is substituted for the solid detergent. It is possible to improve the environmental affinity of sucrose. Preferably, the content of the sucrose powder in the sugar powder can be 20 to 80% by weight. If the content of the sucrose powder is less than 20% by weight, the bubble forming and detergency may be lowered, and if it is more than 80% by weight, the durability of the solid detergent may be lowered.

The sucrose powder is dissolved in water at the time of washing, and sucrose molecules attach and remove contaminants, and can realize a synergistic effect with the sodium lauryl sulfoacetate to maximize the cleaning power. Further, since the sucrose powder can be decomposed by microorganisms after washing, it has excellent environmental affinity and can realize the skin protection effect of the user.

The sucrose powder can be porous particles. The pores of the sucrose powder induce the formation of bubbles to form abundant bubbles, whereby the detergency of the solid detergent can be improved.

The porosity of the porous particles can be 20-80% by volume. If the porosity of the porous particles is less than 20% by volume, the bubble formation and detergency may decrease, and if it exceeds 80% by volume, the durability of the solid detergent may decrease.

On the other hand, the apparent density of the mixture may be 0.5 to 1.5 g / cc, and the apparent density of the solid detergent may be 1.51 to 3.0 g / cc.

As used herein, the term "apparent density" means the density calculated including the particles and the space between the particles. For example, the higher the apparent density of the locked solid detergent, the less space there is and the denser the solid cleaning agent. That is, the higher the apparent density, the stronger the binding of each component.

In the present invention, the mixture is a mixture of sodium lauryl sulfoacetate powder, sugar powder, and sodium hydrogen carbonate powder, and the solid detergent is a mixture obtained by tableting with a tableting machine. Therefore, the binding force between the powders can be increased. That is, the apparent density may increase as the mixture undergoes a tableting process.

If the apparent density of the mixture is less than 0.5 g / cc, the durability of the solid detergent may be lowered, and if it is more than 1.5 g / cc, the detergency may be lowered. Further, if the apparent density of the solid detergent is less than 1.51 g / cc, the durability of the solid detergent may be lowered, and if it is more than 3.0 g / cc, the detergency may be lowered. is there.

On the other hand, the solid detergent may further contain plant essence oil, if necessary. The plant essence oil is a liquid extracted and concentrated from stems, leaf flowers, roots, etc. from plants, and is added to the solid detergent to emit a fragrance, and its effect differs depending on the type. In the invention, the type of plant essence oil can be selected according to the aroma and effect to be obtained.

Specifically, the plant essence oils include Eucalyptus, Peppermint, Lemongrass, Palmarosa, Lavender, Chamomile, and Tea Tree. It may be at least one selected from the group consisting of two or more mixtures, but is not limited thereto.

The solid detergent can be produced in a cylindrical or coin shape. At this time, the diameter of the solid detergent can be adjusted in the range of 7 to 30 mm and individually packaged. If the diameter of the solid cleaning agent is less than 7 mm, the size of the cleaning agent is excessively small, so that the processability and cleaning durability may be lowered. If the diameter is more than 30 mm, bubble generation and cleaning power are lowered. I have something to do.

The solid detergent adjusted to the above range can contain the amount required for one or more cleanings, so that it is convenient to carry and store, and the time to be exposed to the outside is reduced, which is hygienic. Can be managed.

Further, the individual package is formed of a safety cap including an inner cap and an outer cap, and can be easily opened by a certain external force, but it is difficult to open by the force of an infant or a child, and thus is excellent in safety.

Hereinafter, examples of the present invention will be described in detail.

Example 4
The same method as in Example 1 except that a mixture having a water content of 3% by weight was produced by further containing 50% by volume of sucrose powder having a porosity of 50% by volume with respect to the total weight of the water-containing detergent powder. A solid detergent was produced.

Comparative Example 1
Except that the content of each powder was adjusted to 45% by weight of sodium lauryl sulfoacetate powder, 45% by weight of hydrous dextrose powder, and 10% by weight of sodium hydrogen carbonate powder to prepare a mixture having a water content of 3.8% by weight. The solid detergent was produced in the same manner as in Example 1.

Comparative Example 3
A solid detergent was produced in the same manner as in Example 1 except that a mixture containing 60% by weight of anhydrous dextrose powder and having a water content of 0% by weight was produced instead of the water-containing dextrose powder.

Comparative Example 4
The content of each powder was adjusted to 39.5% by weight of lauryl sulfoacetate powder, 60% by weight of hydrous dextrose powder, and 0.5% by weight of sodium hydrogen carbonate powder to prepare a mixture having a water content of 5% by weight. A solid detergent was produced in the same manner as in Example 1 except for the above.

Experimental Example 1: Apparent density of cleaning agent FIGS. 4 and 5 are the measurement results of the apparent density of the powder mixture and the solid cleaning agent according to Example 1, respectively. With reference to FIGS. 4 and 5, the average densities of the powder mixture and the solid detergent according to Example 1 measured over 5 times are shown as 1.4936 g / cc and 1.5182 g / cc, respectively. It was shown that the tablets bound the powders to each other and at the same time the volume of the interpowder voids decreased and the apparent density increased, especially at higher values with an apparent density of 1.5 g / cc as the boundary. It can be seen that the structure and form of the solid detergent can be stably embodied.

Experimental example 2: Performance evaluation of cleaning agent

Referring to Table 1 above, in the case of a solid detergent produced with a mixture containing sodium lauryl sulfoacetate powder, hydrous dextrose powder, and sodium hydrogen carbonate powder having a water content of 5% by weight (Example 1), all performance evaluations were performed. It was shown to be excellent in (degree of bubble generation, disintegration, detergency, durability, usability).

Further, in the case of a solid detergent produced with a mixture in which the content of the hydrous dextrose powder is adjusted so that the water content is adjusted to 4% by weight and 6% by weight, respectively (Examples 2 and 3), there is a slight difference. However, it was shown to be excellent or good in all performance evaluations, and in the case of a solid detergent produced by additionally containing sculose powder (Example 4), it was excellent in all performance evaluations as in Example 1. In particular, it is expected that the excellent detergency of the solid detergent can be expected due to the synergistic effect with other powders.

On the other hand, in the case of a solid detergent containing a small amount or an excessive amount of hydrous dextrose powder (Comparative Examples 1 and 2), the structural and morphological stability of the solid detergent is lowered, and finally durability and usability are reduced. In particular, solid cleaners made from mixtures with a moisture content of 7% by weight are poor in durability and usability because they are easily brittle, making it difficult to sustain and maintain bubbles. there were.

Further, in the case of a solid detergent produced as a mixture containing anhydrous dextrose powder as a sugar powder and having a water content of 0% by weight (Comparative Example 3), the bond and bond retention force between the powders are lowered, and all the performances are improved. It was poor in the evaluation.

On the other hand, when the content of the sodium hydrogen carbonate powder is too low or excessive (Comparative Examples 4 and 5), the mutual binding force of each powder may be lowered, so that all the performance evaluations are lowered, and in particular, Durability and usability were poor.

Experimental Example 3: Evaluation of skin protection performance of detergent The skin protection performance of solid detergent according to Examples was evaluated as follows.

In order to evaluate the skin protection performance of the solid detergent by the surfactant involved in skin damage, the solid detergent containing the sulfate-based surfactant was used in the experiment as the experimental group and Example 1 as the control group.

For the experiment, 10 animals (Rabbits) were set as the subjects of the experiment, the appearance inspection of the health condition of all the individuals was carried out before the introduction into the experiment, and the healthy individuals were used for the experiment after the quarantine and purification period for 8 days. did.

After removing the hair from the backs of the 10 test subjects, immediately before the treatment, two treatment groups and two control groups each having a size of 2.5 cm × 2.5 cm were divided into a scraped part and a non-scraped part, respectively, and the scraped part. Inflicted scratches to the extent that only the epidermis was damaged and the dermis was not damaged.

0.5 mL of the solid detergent according to Example 1 was wetted with gauze and adhered to the treatment group (scraped part 1, non-scraped part 1) for 10 experimental subjects, and the control group (scraped part 1) was attached to the 10 experimental subjects. 0.5 mL of a sulfate-based solid detergent was wetted with gauze and adhered to the scraped site 1 and the non-scraped site 1), and fixed with a non-irritating tape and an elastic bandage so that the gauze was not removed. After 24 hours, the gauze was removed and the material remaining on the skin was washed.

Erythema, edema, and skin irritation index (PII, Primary evaluation index) were evaluated 72 hours after the experimental subjects. At this time, the evaluation criteria and the evaluation results are shown in Tables 2 and 3 below, respectively.

With reference to Table 3 above, when the natural surfactant sodium lauryl sulfoacetate is contained (Example 1), erythema and edema are not formed, the skin irritation index is shown to be 0.3, and the skin protective effect is excellent. It was shown to be. On the other hand, in the case of the sulfate-based detergent, which is a synthetic surfactant, erythema and edema were formed, and the skin irritation index was 4.2, inducing moderate irritation of the skin.
