Description

Technical Field

[0001] The present invention relates to a detergent composition for use in the production of detergents.

Background Art

[0002] In the production of detergents such as shampoos, many raw materials that require heating and melting are used. In particular, shampoos containing a pearling agent, etc., have many raw materials that require heating and melting, such as thickeners, conditioning agents, and pearling agents, and it has taken a long time to dissolve these. Also, in order to obtain a beautiful pearly luster, it has taken time for cooling. Therefore, in the manufacturing process, there has been a problem that it is necessary to perform a step of heating to dissolve the raw materials and a step of cooling, and the compounding takes time.

[0003] Moreover, since it is necessary to perform heating and cooling in the manufacturing process, there is a problem that energy costs are high. In the heating process, a large amount of electric power and fuel are required to maintain a high temperature. Also, in the cooling process, electric power and other energy sources are required to operate a coolant and cooling equipment, etc. Reducing energy costs not only leads to a reduction in manufacturing costs but is also important for fulfilling the responsibility to the environment.

[0004] Also, in order to avoid the step of heating and melting, for example, a method using a pearl conc in which a pearling agent is previously dispersed in a solvent, a liquid type nonionic polymer, and a liquid cationic polymer, etc. can be considered. For example, Patent Document 1 discloses a concentrated pearling agent composition that can impart a pearly luster to a detergent composition. However, there has been a problem that detergents produced without heating and melting using these raw materials do not obtain sufficient quality, such as poor feel.

[0006] Therefore, an object of the present invention is to provide a composition for a cleaning agent capable of improving the production efficiency of the cleaning agent. Means for Solving the Problems

[0007] In order to solve the above problems, the present inventors considered preparing, in advance, a raw material of the cleaning agent that requires heating and melting during production, and preparing a composition (composition for a cleaning agent) that can be said to be a concentrate of the raw materials. However, a composition for a cleaning agent containing a raw material that requires heating and melting at a high concentration becomes highly viscous and is difficult to use in the production of a cleaning agent.

[0008] Therefore, the present inventors intensively studied a method for suppressing the increase in viscosity of the composition for a cleaning agent, and found a method that can uniformly disperse each raw material to make it liquid. The present inventors used an anionic surfactant, which is one of the raw materials of the cleaning agent and has a property of being difficult to thicken, as a solvent to suppress the increase in viscosity. In addition, by adding salts, the increase in viscosity was further suppressed. By combining these devices, they succeeded in uniformly dispersing the raw materials that require heating and melting to make them liquid, and obtained a fluid composition for a cleaning agent that can be used in the production of a cleaning agent.

[0009] When a shampoo was produced using such a composition for a cleaning agent, since there was no need for heating and cooling steps during production, the shampoo could be produced in an extremely short time compared to the production of conventional cleaning agents. Thus, the present inventors found that the production efficiency of cleaning agents such as shampoos can be dramatically improved by using a composition for a cleaning agent that can be said to be a concentrate of the raw materials, and completed the present invention.

[0010] The present invention provides a composition for a cleaning agent containing the following components (A) to (D). (A) Anionic surfactant: 10 to 30% by mass (B) Nonionic surfactant: 5 to 20% by mass (C) Cationic polymer: 0.7 to 3% by mass (D) Salts: 3 to 10% by mass

[0011] The present invention also provides a detergent composition in which the nonionic surfactant contains a pearling agent and the detergent composition has a pearly luster.

[0012] The present invention also provides the above detergent composition which is in a liquid state.

[0013] The present invention also provides the above detergent composition further containing the following component (E). (E) Amphoteric surfactant: 0.01 to 10% by mass

[0015] The present invention also provides a detergent composition in which the anionic surfactant in the above detergent composition is an amino acid-based surfactant.

[0054] The amphoteric surfactant may be 0.01 to 10% by mass, preferably 1 to 8% by mass, for example 3 to 6% by mass, in the detergent composition.

[0055] The detergent composition of the present invention may further contain any components other than components (A) to (E) as long as the object of the present invention is not impaired.

[0056] The detergent composition of the present invention can be in a liquid state. In this specification, "liquid state" means a state in which the components are dissolved or uniformly dispersed in a solvent and have fluidity.

[0057] (Method for producing the detergent composition) The detergent composition of the present invention is not particularly limited. For example, salts of component (D) can be added to the anionic surfactant of component (A), and while heating, component (B) nonionic surfactant and component (C) cationic polymer can be dissolved or dispersed to produce the detergent composition. The detergent composition of the present invention can be produced by mixing the components in an arbitrary procedure in consideration of the heating or cooling temperature required when dissolving and mixing the components.

[0058] For example, first, the anionic surfactant of component (A) may be charged into a preparation tank and then heating may be started. Thereafter, salts of component (D) can be added. The timing of adding the salts of component (D) may be before starting heating, during heating, or after reaching a predetermined temperature. The predetermined temperature is not particularly limited, but can be 30 to 100°C, preferably 40 to 80°C.

[0059] Component (D) salts may be added, and after reaching a predetermined temperature, component (B) nonionic surfactant and component (C) cationic polymer may be added. Component (B) and component (C) may be added simultaneously or sequentially. Also, either of component (B) and component (C) may be added first. While adding or after adding component (B) and component (C), they can be mixed and dissolved by stirring or the like. The addition and mixing dissolution of component (B) and component (C) may be carried out while adjusting the temperature to a predetermined temperature.

[0060] After each component is uniformly dissolved, the composition may be cooled. The cooling method is not particularly limited, and any commonly used cooling method can be used. In the cooling step, although not particularly limited, the composition may be quenched by adding component (E) amphoteric surfactant. The added component (E) is not particularly limited, but preferably can be at 10 to 50 °C. By quenching here, for example, when a pearling agent is used, a good pearling appearance can be obtained.

[0061] (Method for manufacturing a detergent) The detergent produced using the composition for detergent of the present invention is not particularly limited, but can be produced, for example, by charging the composition for detergent and other components into a mixing tank and mixing them. The composition for detergent and other components may be charged simultaneously or sequentially. According to the present invention, since a composition for detergent in which components that require heat dissolution are dissolved or dispersed is prepared in advance, it is possible to prepare a detergent without performing heating and cooling. That is, the detergent is not particularly limited, but can be prepared at room temperature, for example, at 15 to 35 °C. Therefore, the production efficiency can be remarkably improved.

[0062] Other components used in the detergent can be components commonly used in detergents and are not particularly limited. For example, they can be anionic surfactants, nonionic surfactants, amphoteric surfactants, cationic surfactants, cationic polymers, salts, antiseborrheic agents, vitamin agents, bactericides, anti-inflammatory agents, pH adjusters, preservatives, chelating agents, humectants, colorants, plant extracts, amino acids, hydrolyzed proteins, fragrances, ultraviolet absorbers, antioxidants, and oils, etc. In addition, other components are preferably components that do not require heat dissolution.

[0063] The detergent produced using the composition for detergent of the present invention is not particularly limited, but can be a detergent containing at least an anionic surfactant, a nonionic surfactant, a cationic polymer, and salts. The detergent can be, for example, a detergent for hair and / or skin such as shampoo, body soap, facial wash foam, cleansing, hand soap, shaving cream, and massage cream, etc.

Examples

[0064] 〔Example 1: Preparation of Composition for Detergent 1〕 Composition for Detergent 1 was prepared by the following method. The composition and preparation method of Composition for Detergent 1 are shown in Figure 1. The numerical values shown below % in Figure 1 are the blending amounts (mass %) of each component in Composition for Detergent 1.

[0065] In Composition for Detergent 1, as component (A) anionic surfactant, lauroyl sarcosine TEA was used. As component (B) nonionic surfactant, cocamide MEA, palm oil fatty acid PEG-7 glyceryl, and glycol distearate as an opacifier were used. As component (C) cationic polymer, polyquaternium-10 was used. As component (D) salts, a chelating agent, a preservative, an inorganic salt, and an organic acid were used. As component (E) amphoteric surfactant, palm kernel fatty acid amidopropyl betaine was used.

[0066] First, lauroyl sarcosine TEA (20% by mass) and purified water were charged into a mixing tank, and heating was started. After reaching 40 to 70°C, a chelating agent and a preservative (2% by mass in total), and inorganic salts and organic salts (2% by mass in total) were added. Next, glyceryl PEG-7 yate (5% by mass) and polyquaternium-10 (1.5% by mass) were added. Then, it was stirred and mixed until dissolved.

[0067] Next, it was heated to 60 to 80°C, and diglycol distearate (5% by mass) and cocoamid MEA (5% by mass) were added. While maintaining the temperature at 60 to 80°C, it was stirred until uniformly dissolved.

[0068] Next, cooling was started. In the cooling process, palm kernel fatty acid amide propyl betaine (5% by mass) at 10 to 50°C was added, and it was confirmed that the pearl appearance was good. When it was confirmed that the pearl appearance was good, the formulation was completed.

[0069] 〔Example 2: Production of shampoo〕 A shampoo was produced with the composition shown in Table 1 below. While stirring, each component was added to the mixing tank in the order shown in Table 1. Then, it was stirred and mixed for 20 minutes to complete the formulation. During the formulation, neither heating nor cooling was performed. The temperature after formulation was 30°C. The time taken from the start to the end of the formulation was about 2 hours.

[0070] In this example, since the detergent composition 1 prepared in advance was used, heating and cooling were not required in the shampoo production process, and it could be produced simply and in a short time.

[0071]

Table 1

[0072] 〔Comparative Example 1: Production of shampoo〕 Using a conventional method, a shampoo containing a pearlescent agent was produced. The composition and formulation method of the shampoo of Comparative Example 1 are shown in Figure 2.

[0073] First, lauroyl sarcosine TEA and cocooyl glutamate TEA (15% by mass in total) and purified water were charged into a mixing tank, and heating was started.

[0074] Next, while adjusting the temperature in the mixing tank as shown in Figure 2, a chelating agent and a preservative (0.5% by mass in total) and inorganic salts and organic salts (1% by mass in total) were sequentially added. Then, after adding glyceryl PEG-7 palm kernelate (1.2% by mass) and polyquaternium-10 (0.5% by mass), the temperature was adjusted again, and then glycol distearate (1.2% by mass) and cocamide MEA (1.2% by mass) were added and confirmed to be uniformly dissolved.

[0075] Subsequently, cooling was started. Palm kernel fatty acid amide propyl betaine (6.2% by mass), polyquaternium-7 (2% by mass), fragrance (1% by mass), and cocamide methyl MEA (5% by mass) were added, mixed and stirred to complete the formulation. The temperature at the end was 50°C or lower. The time taken from the start to the end of the formulation was about 6 hours.

[0076] [Advantages of the Present Invention] When using the conventional method, it took about 6 hours to manufacture one lot of the product. After adding subsequent inspections, product transfer, and equipment cleaning, it took a considerable amount of time, so it was limited to manufacturing one lot per day.

[0077] On the other hand, if the cleaning agent composition of the present invention is used, several lots of the cleaning agent composition can be manufactured in one day. The cleaning agent can also be manufactured in a shorter time than before by using the cleaning agent composition, so it is possible to manufacture several lots per day. Therefore, by combining the manufacture of the cleaning agent composition and the manufacture of the cleaning agent, the number of manufacturing days can be significantly reduced compared to the conventional method. Also, in the present invention, in the manufacture of the product (cleaning agent) after formulating the cleaning agent composition, temperature adjustment by heating and cooling is not required, and only the timing of ingredient addition needs to be adjusted, so it can be manufactured very simply.

[0078] Furthermore, in the heating and cooling processes, it is necessary to use a large amount of gas, electricity, water, etc. In the conventional method, it was necessary to use a very large amount of gas, electricity, water, etc. every time of production. On the other hand, in the present invention, since the heating and cooling processes are carried out only on the day of manufacturing the detergent composition, the usage amounts of gas, electricity, water, etc. can be significantly reduced.

Industrial Applicability

[0079] The present invention can be suitably used for the production of a composition using a raw material that requires heat melting.
