Description

  The present invention relates to a method for producing a frame kneaded soap having excellent residual fragrance properties.

  Conventionally, a fragrance | flavor is mix | blended with many cleaning agents. By blending the fragrance, it is possible to mask the fabric odor possessed by the cleaning agent and to provide comfort during use. In addition, the scent remaining in the hair, skin, clothing, etc. is very important because it is always the object of consciousness not only by the product user but also by other people. Furthermore, the scent represents the product concept of the product and greatly affects the consumer's willingness to purchase. Thus, the fragrance affects the feeling of use and effects of the product, and has a great physiological psychological effect. Therefore, a fragrance | flavor is calculated | required to maintain a scent after use while being attractive at the time of use.

In recent years, fragrances are also blended in body cleaners that are used after being washed away, such as soaps and liquid detergents, and it is required that the scent continues after use.
For example, Patent Document 1 discloses a soap containing a fragrance.

It is preferable that it is a frame kneaded soap containing.
Next, each component will be described in detail.

(Ingredient (A))
Component (A) is a fatty acid salt of any of alkali metal salts, ammonium salts, and alkanolamine salts.
As a fatty acid which comprises the fatty acid salt of a component (A), a C8-C22 saturated or unsaturated fatty acid can be used. Specific examples include those obtained from vegetable oils and animal oils (for example, palm oil, palm kernel oil, coconut oil, castor oil, soybean oil, cottonseed oil, rapeseed oil, sunflower oil, beef tallow, pork fat, etc.). .
Especially, since the fatty acid salt obtained from palm kernel oil or palm oil contains many lauric acids and myristic acid, since quick foaming property is high, there are many foam amounts, and foam quality becomes creamy, it is preferable.
More preferably, the palm kernel oil fatty acid salt obtained by hydrolyzing palm kernel oil is excellent in terms of odor.

Examples of fatty acid salts include alkali metal salts (for example, sodium salts and potassium salts), ammonium salts, and alkanolamine salts (for example, monoethanolamine salts, diethanolamine salts, and triethanolamine salts).
Of these, alkali metal salts (for example, sodium salt, potassium salt, etc.) are preferable because they have high quick foaming properties and fine foams.
More preferably, a sodium salt is preferable because it raises the Kraft point, so that the soap becomes hard and melts less.

The total amount of the fatty acid salt of component (A) is 25 to 80% by mass, preferably 27% to 47% by mass in the total composition. As the fatty acid salt of component (A), any one of alkali metal salts, ammonium salts, and alkanolamine salts may be used alone, or two or more kinds may be used in combination.
By setting the content of the fatty acid salt to 25% by mass or more, sufficient hardness and foam amount can be obtained, and the soap shape can be maintained.
Moreover, by setting it as 80 mass% or less, the fluidity | liquidity of the molten soap at the time of manufacturing frame kneaded soap can be ensured, and frame kneaded soap with a good external appearance can be obtained.

(Ingredient (B))
Component (B) is a water-soluble inorganic salt.
The water-soluble inorganic salt of component (B) is a salt of an anion such as chloride ion, sulfate ion, carbonate ion, phosphate ion, pyrophosphate ion and alkali metal.
Of these, sodium chloride and sodium sulfate are preferable, and one or a combination of two or more can be used. These water-soluble inorganic salts raise the kraft point, so that the soap can be hardened. Moreover, the fluidity | liquidity of molten soap is improved and the pouring property to a type | mold becomes favorable.

These water-soluble inorganic salts are contained in a total composition of 0.1 to 10% by mass, preferably 2 to 6% by mass.
By setting it as 0.1 mass% or more, it can be set as the frame kneaded soap which has sufficient hardness. Moreover, the foamability of frame kneading soap is securable by setting it as 10 mass% or less.

(Ingredient (C))
The water of a component (C) is 5-70 mass% in the whole composition. By setting the water content to 5% by mass or more, there is an effect of improving the flowability of the molten soap and improving the pouring property to the mold, and by setting it to 70% by mass or less, the hardness of the soap is maintained. effective.

  Content of the fragrance | flavor of a component (D) is 0.01-4 mass%, Especially 0.5-3.0 mass%, Furthermore, 0.7-2.0 mass% is preferable. By setting it as 0.01 mass% or more, the smell of a raw material can be masked reliably, and also fragrance can be reliably left on skin etc. Moreover, the amount of foams can be ensured reliably by making content of a fragrance | flavor 4 mass% or less.

((E) Metal soap)
The metal soap of component (E) is a higher fatty acid salt of a saturated or unsaturated fatty acid having 8 to 22 carbon atoms, or a mixture thereof and a non-alkali metal.
Any non-alkali metal may be used, but examples include metals such as aluminum, silver, barium, beryllium, calcium, cerium, cobalt, chromium, copper, iron, magnesium, manganese, nickel, strontium, thorium, titanium, and zinc. Of these, calcium, aluminum, magnesium and zinc are preferred.
Specific examples of calcium soaps include calcium stearate, calcium palmitate, calcium myristate, calcium oleate, calcium ricinoleate, calcium laurate, calcium behenate, and calcium octoate. Examples of the aluminum soap include aluminum stearate, aluminum palmitate, aluminum behenate, and aluminum octoate. Examples of the magnesium soap include magnesium stearate, magnesium palmitate, magnesium myristate, and magnesium oleate. Examples of the zinc soap include zinc stearate.
In particular, calcium palmitate and calcium stearate, which are calcium soaps, make the skin feel smooth after washing, and by mixing with framed soap as a mixture with a fragrance, the body has a high residual fragrance and is preferable. .
These metal soaps may be used alone or in combination of two or more.

The content of the component (E) metal soap is 0.1 to 10% by mass, particularly 0.5 to 5.0% by mass,
Furthermore, 1.0-4.0 mass% is preferable.
By setting the content of the metal soap to 0.1% by mass or more, when using the framed soap, it is possible to increase the residual fragrance to the skin and prevent the framed soap from being deformed. Moreover, sufficient foam amount can be maintained by making content of metal soap into 10 mass% or less.

The present invention includes (A) a fatty acid salt of any one of alkali metal salt, ammonium salt, and alkanolamine salt, (B) water-soluble inorganic salt, (C) water mixture, (D) perfume and (E) metal. It is a manufacturing method of the frame kneaded soap which mixes with the soap mixture. In the conventional method for producing a framed soap, a perfume is added at the end of the process in order to prevent the perfume from evaporating at a high temperature. However, with this method, it is difficult to suppress the perfume volatilization, and the persistence of the scent to the body is also poor.
On the other hand, the fragrance | flavor and volatilization can be reliably prevented by mixing a fragrance | flavor and metal soap in advance like this invention, and making a metal soap adsorb | suck a fragrance | flavor. Further, when the soap is used on the body, the metal soap to which the fragrance is adsorbed is preferentially adsorbed on the body, so that the persistence of the scent to the body can be further increased.

The mass ratio of component (D) / component (E) used in the present invention is preferably 1/10 to 10/1.
By setting it as 1/10 or more, a fragrance | flavor and a metal soap can be made to contact reliably, it can be set as soap with a quick fragrance at the time of use, and the high residual fragrance property to the skin after washing | cleaning. Moreover, by setting it as 10/1 or less, it can be set as the soap with the high residual fragrance property to skin, without the skin after washing | cleaning getting creased. Among these, 1/1 to 5/1, which has high foaming properties during use and high residual fragrance on the skin, is preferable.

Furthermore, the frame kneaded soap of the present invention can contain a metal ion sequestering agent (component (F)) from the viewpoint of preventing quality deterioration such as odor and discoloration and generation of metal scum.
In particular, hydroxyethanediphosphonic acid or a salt thereof, or ethylenediaminetetraacetic acid or a salt thereof has a function of suppressing generation of metal soap formed by a reaction between a metal ion and a fatty acid contained in water to be washed away. Due to this function, the metal soap brought into contact with the fragrance has a role of effectively adsorbing to the skin. Therefore, the residual fragrance property of skin becomes higher.
The content of the sequestering agent is preferably 0.01 to 1% by mass, and in particular when 0.05 to 0.5% by mass is washed, soap in water can be quickly removed, and the residual fragrance can be enhanced. .

The frame kneaded soap of the present invention can contain a polyol from the viewpoint of giving a moisturizing feeling after towel drying.
Examples of these polyols include glycerin, sorbitol, mannitol, glucose, polyethylene glycol, polypropylene glycol, and water-soluble polysaccharides. Among them, the molecular weight of polyethylene glycol and polypropylene glycol is preferably 8000 or less, and examples of the water-soluble polysaccharide include sucrose, trehalose, hydroxyethyl cellulose, hydroxypropyl cellulose, and the like, and glycerin and sorbitol are particularly preferable.
These polyols can be used alone or in combination of two or more. It is preferable that 0.1% by mass or more, particularly 1% by mass or more and 30% by mass or less, further 15% by mass or less, and particularly 10% by mass or less are contained in the total composition.

The framed soap of the present invention can contain an amphoteric surfactant, a nonionic surfactant, and an anionic surfactant other than the component (A) from the viewpoint of further increasing the amount of foam.
Examples of amphoteric surfactants include betaine surfactants, amino acid surfactants, imidazoline surfactants, amino oxide surfactants, and the like.
One or more amphoteric surfactants can be used, and the total composition preferably contains 0 to 10% by mass, particularly 0.1 to 5% by mass, and more preferably 0.5 to 4% by mass.
Examples of nonionic surfactants include nonionic surfactants such as polyoxyalkylene surfactants, hydroxy acid ester surfactants, sucrose ester surfactants, and lactate ester surfactants.
These nonionic surfactants are preferably contained in an amount of 15% by mass or less, more preferably 0.1% by mass or more and 8% by mass or less.
The anionic surfactant other than the component (A) is not particularly limited as long as it is used in an ordinary detergent composition. For example, an alkyl sulfate, an alkyl ether sulfate, a polyoxyalkylene alkyl ether sulfate, Alkyl sulfonate, alkyl amide sulfonate, alkyl aryl sulfonate, alkyl benzene sulfonate, olefin sulfonate, paraffin sulfonate, alkyl sulfosuccinate, alkyl ether sulfosuccinate, polyoxyalkylene alkyl ether carboxylic acid Salt, alkylamide sulfosuccinate, alkyl succinamide salt, alkyl sulfoacetate, acyl sarcosine salt, acyl isethionate, alkenyl succinate, alkyl ether acetate, polyoxyalkylene alkyl acetate Acetate; Phosphate such as alkyl phosphate, alkyl ether phosphate, polyoxyalkylene alkyl ether phosphate; N-acyl taurine salt, N-acyl glycine salt, N-acyl alanine salt, N-acyl Examples include acylated amino acid salts such as glutamate and N-acyl aspartate.
These anionic surfactants are preferably contained in an amount of 15% by mass or less, more preferably 0.5% by mass or more and 10% by mass or less.
The surfactants can be used alone or in combination of two or more.

The frame kneaded soap of the present invention can also contain a high molecular compound such as high molecular weight polyethylene glycol, cationic polymer, cellulose, carboxymethyl cellulose, and methyl cellulose from the viewpoint of enhancing foam slip.
One or more kinds of these polymer compounds can be used, and 0 to 5% by mass, particularly 0.1 to 3% by mass, and more preferably 0.25 to 2% by mass in the total composition is contained.

  The framed soap further contains components usually used in cosmetics, for example, surfactants other than those mentioned above, water-soluble solvents, thickeners, bactericides, moisturizers, wetting agents, colorants, preservatives, and feel improvers. , Perfume, antibacterial inflammation, whitening agent, antiperspirant, ultraviolet absorber and the like can be appropriately contained.

Furthermore, the frame kneaded soap of the present invention can contain bubbles from the viewpoint of speeding up foaming. The framed soap can be manufactured as follows.
For example, components (A) to (E) and other components are added as necessary and dissolved by heating. The heating temperature is about 65 ° C to 90 ° C. Thereby, a molten soap is obtained. The obtained molten soap is poured as it is into a mold and cooled and solidified. As a result, a frame kneaded soap composition is obtained. If desired, moisture contained in the molten soap may be removed to some extent before and / or after cooling and solidification. In particular, when manufacturing lightweight (floating) soap containing bubbles, the resulting melt is subjected to aeration treatment with a domestic or industrial whip device to contain bubbles, and the resulting bubbles are contained. It can be manufactured by placing the melt in a mold, cooling and solidifying, and drying as necessary. The aeration referred to here is a process in which bubbles such as air or nitrogen are ejected to the molten soap, and is sometimes referred to as an aeration process.

The above-mentioned frame kneaded soap is manufactured as follows.
(A) a fatty acid salt of any one of an alkali metal salt, an ammonium salt and an alkanolamine salt, (B) a mixture of a water-soluble inorganic salt, (C) water, and (D) a mixture of a fragrance and (E) a metal soap Are mixed and manufactured.
If it demonstrates in detail, component (A), (B), (C) will be heated and stirred at 55-95 degreeC.
On the other hand, the mixture which mixed the component (D) and the component (E) is manufactured. Specifically, the component (D) and the component (E) are mixed and shaken until the component (D) and the component (E) are uniformly dispersed.
Thereafter, the mixture of the component (D) and the component (E) is allowed to stand at room temperature for 12 hours or more, preferably 24 hours or more. Thus, by mixing the fragrance | flavor of a component (D) and the metal soap of a component (E) previously, when framed soap is used, a residual fragrance property increases. In particular, by leaving the mixture of the component (D) and the component (E) for a predetermined time (12 hours or more), the residual fragrance when using the framed soap is further increased.
The reason why the residual fragrance is increased is as follows. The fragrance adheres to the metal soap and is carried. Therefore, when using a frame kneaded soap, the metal soap to which the fragrance is attached remains on the skin and the like, and the residual fragrance property is increased.
Thereafter, the mixture containing the components (A), (B) and (C) and the mixture containing the components (D) and (E) are mixed and melted to obtain a molten soap.
Next, molten soap is poured into a mold, cooled, solidified, and dried to obtain a framed soap.
In addition, components other than (A) to (E) may be added to the mixture of (A) to (C), or may be added to the mixture of (D) and (E). Furthermore, after the mixture of (A) to (C) and the mixture of (D) and (E) are mixed, other components may be mixed.
However, it is preferable to add other components to the mixture of (A) to (C) in order to reliably attach the fragrance to the metal soap.
The frame kneaded soap obtained by the manufacturing method as described above has a high residual fragrance.

Here, as methods for enhancing the residual fragrance, Patent Documents 2 and 3 describe a method of encapsulating a fragrance with cyclodextrin in order to provide long-term fragrance retention.
However, there is a problem that a special technique is required for producing a fragrance using a cyclodextrin as a carrier described in Patent Documents 2 and 3, which is not simple and causes an increase in cost.
On the other hand, in this embodiment, it is only necessary to preliminarily mix the fragrance and the metal soap, and it is not necessary to use a special carrier, so while using the raw materials conventionally used for the frame kneaded soap Therefore, it can be easily manufactured and cost increase can be suppressed.

(Composition of mixed solution)
According to the ratio (parts by mass) shown in Table 1, the component (D) and the component (E) were combined with the Mighty Vial No. 5 The total of component (D) and component (E) was set to 20 g. At room temperature, shake with a vortics mixer (LAB-MIXER HM-10H Memory 5 Iuchi) until it is uniformly mixed, then let stand at room temperature for 24 hours, then mixed solution 1 of component (D) and component (E) 1 ~ 5 were created.
In addition, although it was left to stand for 24 hours here, not only this but 12 hours or more are preferable.
