Description

Technical Field

[0001] The present invention relates to an agent for suppressing hair undulation, a cosmetic, an agent for suppressing hair spreading, an agent for improving a foaming detergent, and a method for producing a hair cosmetic and a method for producing a foaming detergent, which contain a predetermined reduced maltose as an active ingredient.

Background Art

[0002] Hair undulation is one of the common hair styling problems, and it often gets worse in humid seasons such as the rainy season. The causes include genetics, distortion of hair roots and hair follicles due to aging, uneven absorption of moisture from the damaged and partially peeled cuticle, and uneven expansion of the hair inside.

[0003] Conventionally, in order to suppress hair undulation, procedures such as undergoing hair straightening by a beautician, devising the drying method of wet hair (drying while pulling downwards), and scalp massage to improve blood flow and adjust the scalp environment have been carried out. Patent Document 1 discloses a hair cosmetic for suppressing undulation, which contains a compound selected from beeswax, a polymer containing a phosphorylcholine group, and one or more selected from cationized polysaccharides, and an ester oil that is liquid at 20°C.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, hair straightening treatments have the drawback that while the treated area is less frizzy, the effect does not extend to the new hair that grows daily, making the effect temporary. Furthermore, the effectiveness of drying methods and scalp massages varies depending on the skill of the practitioner, which presents another challenge. In addition, the technology described in Patent Document 1 requires the inclusion of considerable amounts of cationic polymers and oily components, which limits the flexibility of formulation design and makes it difficult to apply to a wide range of products.

[0006] As described above, even considering the prior art, there is not a sufficient supply of technology for suppressing hair frizz. The present invention was made to solve this problem and aims to provide a technology for suppressing hair frizz in a simple manner without limiting the freedom of formulation design.

[0023] The present invention will be described in detail below.

[0024] "Suppressing hair waviness" means reducing the degree of hair waviness, and includes not only straightening the hair, but also ensuring that even when the hair is wavy, the degree of waviness is less than when the present invention is not used.

[0025] The degree of waviness can be evaluated by the length of the hair in a state where no tension is applied, such as pulling from below (for example, when suspended), as shown in the examples described later. This is because, in such a state, the greater the degree of waviness, the shorter the length of the hair. Therefore, by comparing the length of the hair in such a state with and without using the present invention, if the former is longer, it can be evaluated that the waviness of the hair has been suppressed by the present invention.

[0026] As mentioned above, hair frizz tends to increase under high humidity conditions, but the present invention can be used to suppress frizz under high humidity conditions. Here, since humidity (relative humidity) is generally considered uncomfortable when it exceeds around 60%, high humidity can be exemplified by humidity levels exceeding 60%, 65% or higher, 70% or higher, 75% or higher, 80% or higher, or 85% or higher.

[0027] "Suppressing hair spreading" means reducing the degree of hair spreading, and includes not only a state where the hair is not spread at all, but also a state where, even if the hair is spread, the degree of spreading is smaller compared to when the present invention is not used.

[0028] The degree of hair spread can be evaluated by measuring the volume (outermost volume) surrounding the outermost area where the hair is located, while the hair is not subjected to any tension, such as being pulled from below (for example, suspended). Alternatively, an image may be taken in this state, and the area (outermost area) surrounding the outermost area where the hair is located on the image may be measured and evaluated. In this state, the greater the degree of hair spread, the larger the measured value of the outermost volume or outermost area will be. Therefore, by comparing the outermost volume and outermost area in this state with and without the present invention, if the former is smaller, it can be evaluated that the hair spread has been suppressed by the present invention.

[0029] "Hair cosmetics" refer to cosmetics intended for use on the scalp and hair. Specific examples of hair cosmetics include styling products such as styling creams, hair waters, hair foams, and hair gels; hair nourishing products such as hair lotions, hair treatments, hair conditioners, and hair packs; scalp treatments; hair coloring products such as color rinses and hair manicures; shampoos and other hair washes; and hair rinses.

[0030] A cleaning agent is a product intended to remove dirt. A "foaming cleaning agent" is a cleaning agent that generates bubbles and has the property of foaming when water is added in an appropriate amount. Specific examples of foaming cleaning agents include shampoos and other hair washing products, bar soaps, makeup removers (cleansers), facial cleansers, body washes, and all-in-one shampoos.

[0031] "Accelerating the foaming of foaming detergents" means shortening the time it takes for bubbles or aggregates of bubbles to form when foaming a foaming detergent. Whether or not this time has been shortened can be evaluated by sensory testing, as shown in the examples described later, when using the present invention versus when not using it. Alternatively, it can be evaluated by measuring the time it takes to reach a certain amount of foam using a machine such as a mixer. If the former method results in a shorter time, it can be concluded that the foaming of the foaming detergent has been accelerated by the present invention.

[0032] "Increasing the amount of foam in a foaming detergent" means increasing the volume of the aggregate of bubbles generated when the foaming detergent is foamed. Whether or not this volume has increased can be evaluated by sensory testing, as shown in the examples described later, when using the present invention versus when not using it. Alternatively, it can be evaluated by foaming for a certain period of time using a machine such as a mixer and measuring the volume of the resulting aggregate of bubbles. If the volume is larger in the former case, it can be concluded that the amount of foam in the foaming detergent has increased due to the present invention.

[0033] "Improving the elasticity of the foam of a foaming detergent" means increasing the elasticity of the aggregate of bubbles generated when the foaming detergent is lathered. Whether or not this elasticity has increased can be evaluated by sensory testing, as shown in the examples described later, with and without the present invention.

[0034] "Reduced starch syrup" is a type of sugar alcohol obtained by reducing starch syrup. Here, starch syrup is a substance obtained by saccharifying starch with acid or enzymes, and is a mixture of monosaccharides (glucose) and polysaccharides (oligosaccharides, dextrin, etc.). Therefore, reduced starch syrup is also a mixture containing two or more sugar alcohols from among monosaccharide sugar alcohols and polysaccharide (disaccharide, trisaccharide, tetrasaccharide, or pentasaccharide or more) sugar alcohols.

[0035] Reduced starch syrup can be classified into the following categories (a) to (c) depending on the degree of saccharification; (a) Highly saccharified reduced starch syrup (sugar composition of 30-50% by mass of monosaccharides, 20-50% by mass of disaccharides, and 25% by mass or less of trisaccharides or higher), (i) Reduced starch syrup (sugar composition with less than 30% monosaccharides by mass and less than 50% pentasaccharides or more by mass), (c) Low-saturation reduced starch syrup (sugar composition of five sugars or more, with five sugars or more making up 50% by mass).

[0036] The hair frizz inhibitor and hair frizz inhibitor cosmetic according to the present invention can use any of the above (a) to (c) as active ingredients. The hair spread inhibitor, the agent that accelerates the foaming of foaming cleansing agents, the agent that increases the amount of foam in foaming cleansing agents, and the agent that improves the elasticity of foam in foaming cleansing agents according to the present invention use the above (b) reduced saccharified starch syrup as an active ingredient.

[0037] In the present invention, the sugar composition of the medium-saccharified reduced starch syrup may be, in addition to (a) above, 2 to 10% by mass of monosaccharides, 15 to 25% by mass of disaccharides, 50 to 65% by mass of trisaccharides, 1 to 15% by mass of tetrasaccharides, and 1 to 15% by mass of pentasaccharides or more.

[0038] Furthermore, "sugar composition" refers to the percentage of the total mass of each sugar relative to the total mass of sugars. In other words, it is the percentage of the mass of each sugar relative to the total mass of sugars, which is set to 100.

[0039] The sugar composition can be determined using high-performance liquid chromatography (HPLC). Specifically, reduced starch syrup or starch syrup is subjected to HPLC as a sample to obtain a chromatogram. In this chromatogram, the sum of the areas of all peaks corresponds to the "total mass of sugars," and the area of ​​each peak corresponds to the "mass of each sugar." Therefore, the mass percentage of each sugar in the sample can be calculated as the ratio of the area of ​​each peak to the sum of the areas of all detected peaks. The HPLC conditions can be set appropriately according to standard procedures, but the following conditions are examples. HPLC conditions Column; MCI GEL CK04S (10mm ID x 200mm) Eluent; high purity water Flow rate; 0.4mL / min Injection volume: 20μL Column temperature: 65°C Detection; Differential refractive index detector RI-10A (Shimadzu Corporation)

[0040] The "Dextrose Equivalent (DE)" is the percentage of reducing sugars in a sample relative to the total solid content, measured as glucose. It is used as an indicator of the degree of saccharification of corn syrup. A maximum DE of 100 means that all of the solid content is glucose, while a lower DE means that there are more oligosaccharides and polysaccharides. For example, corn syrup with a DE of 70-46 is classified as high-saccharification corn syrup, and the reduced corn syrup obtained by reducing it is classified as high-saccharification reduced corn syrup. Corn syrup with a DE of 45-31 is classified as medium-saccharification corn syrup, and the reduced corn syrup obtained by reducing it is classified as medium-saccharification reduced corn syrup. Corn syrup with a DE of 30 or less is classified as low-saccharification corn syrup, and the reduced corn syrup obtained by reducing it is classified as low-saccharification reduced corn syrup.

[0041] The hair frizz suppressant and hair frizz suppressant cosmetic according to the present invention can use either highly saccharified or low saccharified reduced starch syrup as an active ingredient. Therefore, the reduced starch syrup can be (e) a reduced product of starch syrup with a DE of 14 or more and 70 or less.

[0042] Furthermore, since the hair spreading inhibitor, the agent for accelerating the foaming of foaming cleansing agents, the agent for increasing the amount of foam in foaming cleansing agents, and the agent for improving the elasticity of foam in foaming cleansing agents all use moderately saccharified reduced starch syrup as an active ingredient, the reduced starch syrup can be a reduced product of starch syrup with (o) DE of 31 or more and 45 or less.

[0043] The DE of corn syrup can be measured by the following method. 《Method for measuring DE》 Accurately weigh 2.5 g of the sample and dissolve it in water to make 200 mL. Measure 10 mL of this solution, add 10 mL of 1 / 25 mol / L iodine solution (Note 1) and 15 mL of 1 / 25 mol / L sodium hydroxide solution (Note 2), and leave in the dark for 20 minutes. Next, add 5 mL of 2 mol / L hydrochloric acid (Note 3) and mix, then titrate with 1 / 25 mol / L sodium thiosulfate solution (Note 4). When the solution turns slightly yellow near the titration endpoint, add 2 drops of starch indicator (Note 5) and continue the titration. The titration endpoint is reached when the color of the solution disappears. Determine the blank value using water and calculate DE using the following formula 1. TIFF0007897585000001.tif49165

[0044] (Note 1) 1 / 25 mol / L iodine solution: Place 20.4 g of potassium iodide and 10.2 g of iodine in a 2 L volumetric flask, dissolve with a small amount of water, then add water to the mark. (Note 2) 1 / 25 mol / L sodium hydroxide solution: Place 3.2 g of sodium hydroxide in a 2 L volumetric flask, dissolve it in a small amount of water, and then add water up to the mark. (Note 3) 2 mol / L hydrochloric acid: Gradually add 150 mL of hydrochloric acid to 750 mL of water while stirring. (Note 4) 1 / 25 mol / L sodium thiosulfate solution: Place 20 g of sodium thiosulfate in a 2 L volumetric flask, dissolve with a small amount of water, then add water to the mark. (Note 5) Starch indicator: Dissolve 5 g of soluble starch in 500 mL of water, and then dissolve 100 g of sodium chloride in this solution.

[0045] Reduced starch syrup may be used as is if it is commercially available, or it may be manufactured and used according to a method known to those skilled in the art. Examples of commercially available high-saccharification reduced starch syrup include "Sweet PEM", "SE 600", "SE 600P", and "SE 500" (all from Bussan Food Science), examples of commercially available medium-saccharification reduced starch syrup include "Aqua All #1", "Sweet OL", and "SE 57" (all from Bussan Food Science), and examples of commercially available low-saccharification reduced starch syrup include "Aqua All #2", "Sweet NT", "SE 30", and "SE 100" (all from Bussan Food Science), "PO-10", and "PO-20" (all from Mitsubishi Corporation Life Science).

[0046] A known method for producing reduced starch syrup involves a reduction reaction in which hydrogen is added to the raw material, starch syrup (raw sugar). For example, in a reduction reaction by hydrogenation, a 40-75% by mass aqueous solution of raw sugar is charged into a high-pressure reactor together with a reduction catalyst. The reaction is carried out while mixing and stirring at a hydrogen pressure of 4.9-19.6 MPa and a reaction solution temperature of 70-180°C until no further hydrogen absorption is observed. After that, the reduction catalyst is separated, and the mixture is decolorized and desalted by ion exchange resin treatment, activated carbon treatment if necessary, and then concentrated to a predetermined concentration to produce high-concentration reduced starch syrup.

[0047] Reduced starch syrup can be used as a raw material in the usual process of manufacturing cosmetics and cleansing products. In other words, the present invention also provides a method for manufacturing hair cosmetics, comprising the step of incorporating the hair frizz suppressant according to the present invention as a raw material. Furthermore, the present invention also provides a method for manufacturing a foaming cleansing product, comprising the step of incorporating an agent that accelerates the foaming of the foaming cleansing product, an agent that increases the amount of foam in the foaming cleansing product, or an agent that improves the elasticity of the foam in the foaming cleansing product as a raw material.

[0048] The method of incorporating reduced starch syrup in the manufacture of cosmetics and cleansing products can be carried out appropriately by methods known to those skilled in the art, depending on the type of product, the type and amount of other raw materials, and the desired feel. Since reduced starch syrup is a polyhydric alcohol, it can be handled in the same way as other conventionally used polyhydric alcohols such as glycerin, 1,3-butylene glycol, propylene glycol, dipropylene glycol, and pentylene glycol when manufacturing cosmetics and cleansing products.

[0049] In addition to containing reduced starch syrup, cosmetics and cleansing products may contain other ingredients (for example, surfactants, solvents, dispersion media, other polyhydric alcohols, preservatives, chelating agents, pH adjusters, other sugars such as sorbitol, colorants, plant and animal extracts, vitamins, inorganic salts, organic salts, solubilizers, bactericides, humectants, antioxidants, wetting agents, UV absorbers, thickeners, fragrances, cationic polymers, cooling agents, chilling agents, oils, etc.) as long as they do not impair the characteristics of the present invention.

[0050] The amount of reduced starch syrup used in cosmetics can also be appropriately set according to the type of cosmetic, the types and amounts of other raw materials, and the desired feel. For example, assuming a total mass of 100% by mass of the cosmetic, from the viewpoint of obtaining a waviness-suppressing effect, the lower limit of reduced starch syrup is preferably more than 0.5% by mass, and more preferably 1.0% or more, 1.5% or more, 2.0% or more, or 2.5% or more by mass. The upper limit is preferably 20% or less by mass.

[0051] The amount of reduced starch syrup used in a cleansing agent can also be appropriately set according to the type of cleansing agent, the types and amounts of other raw materials, and the desired feel. For example, assuming a total mass of 100% by mass of the cleansing agent, from the viewpoint of obtaining an effect of accelerating foam formation, increasing foam volume, or improving foam elasticity, the lower limit of reduced starch syrup is preferably more than 0.5% by mass, and more preferably 1.0% or more, 1.5% or more, 2.0% or more, or 2.5% or more by mass. The upper limit is preferably 20% or less by mass.

[0052] The present invention will be described below based on various embodiments. However, the technical scope of the present invention is not limited to the features shown in these embodiments. [Examples]

[0053] <Test Method> Unless otherwise specified, the tests were conducted using the following methods. (1) Test substance The test substances used were those listed in Table 1 (all commercially available products). For sugar alcohols, their sugar composition and the DE value of the raw sugar are also shown in Table 1. [Table 1]

[0054] (2) Formulation of shampoo and conditioner Table 2 shows the formulations of the shampoo and conditioner used in this example. [Table 2]

[0055] (3) Manufacturing of shampoo The shampoo was prepared using the formulations shown in Table 2, following the steps [1]-[4] below. [1] Sodium laureth sulfate and sodium lauroyl methylalanine were weighed into a container and stirred. [2] Lauryl betaine, cocamide methyl MEA, the test substance, polyquaternium-10, polyquaternium-7, phenoxyethanol, EDTA-2Na, and citric acid were weighed into a separate container and heated and stirred at 75°C to 80°C. [3] [2] was mixed with [1] and cooled and stirred until the temperature reached 35°C to 40°C. [4] After cooling, the fragrance was added to [3] and stirred, and the total volume was adjusted by adding purified water as needed, completing the preparation.

[0056] (4) Manufacturing of treatments The treatment was prepared using the formulations shown in Table 2, following the steps [1]-[5] below. [1] Purified water, PEG-115M, phenoxyethanol, and the test substance were weighed into a container and heated and stirred at 75°C to 80°C. [2] Stearyl alcohol, behenyl alcohol, paraffin, and phytosqualane were weighed into a separate container and heated and stirred at 75°C to 80°C. [3] and [2] were mixed with [1] using a homomixer. [4] and [3] were cooled to 35°C to 40°C, and dimethicone and fragrance were added and stirred. The total volume was adjusted by adding water as needed. [5] and [4] were degassed, and the preparation was completed.

[0057] <Example 1> Swell suppression effect In this embodiment, hair bundles (Beaulux) of wavy Indian hair (approximately 3g and 30cm per bundle) were used. The length of the hair bundles was measured while they were suspended, as shown in Figure 1, without applying any tension such as pulling from below.

[0058] (1) Investigation using a 5% aqueous solution Aqueous solutions containing 5% by mass of glycerin, sorbitol, high-saccharification reduced starch syrup, medium-saccharification reduced starch syrup, and low-saccharification reduced starch syrup were prepared and used as test solutions. Water was also used as a control solution. These test solutions were subjected to waviness evaluation tests according to the following procedures [1]-[5]. [1] The hair was pre-washed with 0.1 mL of an aqueous solution containing 10% by mass of sodium laureth sulfate (solid content) per bundle. [2] Hair samples were suspended in a constant temperature and humidity chamber and allowed to air dry for 24 hours under conditions of 25°C and 45% humidity. Afterwards, the length of the hair strands was measured and photographed (Condition 1, before treatment). [3] After immersing each bundle of hair in 100 mL of the test solution for 10 minutes, the hair was removed and combed 10 times. The bundles were then suspended in a constant temperature and humidity chamber, and the length of the hair bundles was measured and photographed (Condition 2, immediately after treatment). [4] The suspended hair was stored for 24 hours under conditions of 25°C and 45% humidity. The length of the hair bundles was measured and photographed 6 hours after the start of storage (condition 3, stored at 45% humidity). [5] Next, the hair was stored for 6 hours under conditions of 25°C and 90% humidity, after which the length of the hair bundles was measured and photographed (condition 4, stored at 90% humidity).

[0059] Figure 1 shows the images taken for states 1 to 4, and Table 3 shows the measurement results of the hair bundle length (unit: mm These are shown below. In Table 3, the values ​​in parentheses for State 3 and State 4 show the difference (change value) from the hair bundle length in State 2. [Table 3]

[0060] As shown in Table 3 and Figure 1, when water, glycerin aqueous solution, and sorbitol aqueous solution were used as the test solution, the change in hair bundle length in state 4 was -9.5 to -9.0. mm The hair strand length was significantly shorter compared to state 2. In contrast, when using medium-saccharification reduced starch syrup aqueous solution, low-saccharification reduced starch syrup aqueous solution, and high-saccharification reduced starch syrup aqueous solution, the change in hair strand length in state 4 was -1.5 to +1.0. mm The result was almost the same as state 2. From these results, it became clear that high-saccharification reduced starch syrup, medium-saccharification reduced starch syrup, and low-saccharification reduced starch syrup can suppress hair frizz.

[0061] (2) Investigation using a 3% aqueous solution Aqueous solutions containing 3% by mass of medium-saccharified reduced starch syrup, low-saccharified reduced starch syrup, and a glycosyl trehalose / maltooligosaccharide alcohol mixture (hereinafter referred to as "GM mixture") were prepared and used as test solutions. Water was also used as a control solution for comparison. A waviness suppression test was performed on these test solutions using the same procedure as in Example 1(1). Images taken for states 1 to 4 are shown in Figure 2, and the measurement results of hair bundle length are shown in Table 4. In Table 4, the difference (change value) from the hair bundle length in state 2 is shown in parentheses. [Table 4]

[0062] As shown in Table 4 and Figure 2, in both state 3 and state 4, the absolute value of the change in hair bundle length was significantly smaller when using medium-saccharification reduced starch syrup aqueous solution and low-saccharification reduced starch syrup aqueous solution compared to when using water or GM mixture aqueous solution. In particular, in state 4, the change value when using water was -24.5. mm While the time was significantly shorter with the medium- and low-saccharification reduced starch syrup solutions, the change in time when using those solutions was -2 to -0.5. mm The result was almost the same as state 2. From these results, it became clear that the medium-saccharification reduced starch syrup aqueous solution and the low-saccharification reduced starch syrup aqueous solution can suppress hair frizz.

[0063] (3) Examination of shampoo and conditioner formulations Shampoo and conditioner were prepared using medium-saccharified reduced starch syrup and a GM mixture as test substances. Using these, a frizz suppression test was conducted according to the following procedures [1]-[7]. [1] Comb the dry hair 10 times. Then, comb the hair 10 times while showering it. [2] After combing wet hair 10 times, the length of the hair strands was measured (Condition 1, before treatment). [3] Apply 1g of shampoo to each strand of hair and comb through 10 times. Comb through 10 more times to create a lather. Then rinse by running a shower over the hair and combing through 10 times. [4] After combing wet hair 10 times, apply 1g of treatment per strand of hair and comb 10 times. Then rinse by combing 10 times while showering the hair. [5] After combing wet hair 10 times, the length of the hair strands was measured (Condition 2, immediately after treatment). [6] The hair was suspended and stored for 24 hours under conditions of 25°C and 45% humidity. The length of the hair bundles was measured 6 hours after the start of storage (condition 3, 45% humidity). [7] Next, the hair was stored for 6 hours under conditions of 25°C and 90% humidity, and then the length of the hair bundles was measured (condition 4, stored at 90% humidity).

[0064] Table 5 shows the measurement results of hair bundle lengths for conditions 1 to 4 (unit: mm As shown in Table 5, the values ​​in parentheses for State 3 and State 4 indicate the difference (change value) from the hair bundle length in State 2. [Table 5]

[0065] As shown in Table 5, in both state 3 and state 4, the change in hair bundle length was significantly smaller in absolute value when the shampoo and conditioner contained reduced starch syrup than when the GM mixture was contained. In other words, the former resulted in significantly less hair waviness than the latter. From these results, it is clear that hair waviness can be effectively suppressed by incorporating reduced starch syrup into hair cosmetics.

[0066] <Example 2> Spread suppression effect In this example, hair bundles of straight Asian hair (Beaulux) (approximately 3g and 30cm per bundle) were used. Shampoo and conditioner were prepared using glycerin and medium-saccharification reduced starch syrup as test substances. Using these, a spread inhibition test was conducted according to the following procedures [1]-[7]. [1] Dry hair was bleached three times. [2] After combing dry hair 10 times, a photograph was taken (Condition 1, before treatment). [3] Next, I ran a shower over my hair and combed it 10 times. I then removed the excess water from my hair with a towel and combed it 10 times. [4] Apply 1g of shampoo to each strand of hair and comb through 10 times. Comb through 10 more times to create a lather. Then rinse by running a shower over the hair and combing through 10 times. [5] After combing wet hair 10 times, apply 1g of treatment per strand of hair and comb 10 times. Then rinse by combing 10 times while showering the hair. Remove excess water from the hair with a towel and comb 10 times. [6] The hair was suspended and stored for 18 hours under conditions of 25°C and 45% humidity, then air-dried before being photographed (Condition 2, after 18 hours). [7] After leaving the samples for another 6 hours under the same conditions, a photograph was taken (condition 3, 24 hours later).

[0067] For images taken in states 1 to 3, the area enclosed by the outermost region where hair exists on the image (degree of hair bundle spread) was measured using the image processing software "ImageJ". Measurements were performed for three samples for each state, and the average area (number of pixels) was calculated. The results are shown in Figure 3. In addition, for the average area of ​​states 2 and 3, the percentage was calculated relative to the average area of ​​state 1 (which was set to 100%), and this was used as the rate of change. The results are shown in Table 6. [Table 6]

[0068] As shown in Figure 3 and Table 6, when glycerin was added to the shampoo and conditioner, the rate of change after 18 hours was 96%, which was smaller than condition 1 (before treatment), but the rate of change after 24 hours was 108%, which was larger than condition 1 (before treatment). In contrast, when medium-saccharification reduced starch syrup was added to the shampoo and conditioner, the rate of change after both 18 and 24 hours was below 100%, and the area was smaller than condition 1 (before treatment). In other words, when glycerin was added to the shampoo and conditioner, the hair spread out more than before treatment after a long period of time, but when medium-saccharification reduced starch syrup was added, the hair did not spread out more than before treatment even after a long period of time, and a more manageable state was maintained. From these results, it is clear that medium-saccharification reduced starch syrup can suppress hair spreading.

[0069] <Example 3> Sensory evaluation Shampoo and conditioner were prepared using glycerin and medium-saccharification reduced starch syrup as test substances. The product containing glycerin was designated A, and the product containing medium-saccharification reduced starch syrup was designated B. A panel of 9 people (2 males, 7 females, A to Jin) applied equal amounts of "Shampoo A and Conditioner A" and "Shampoo B and Conditioner B" to the left and right halves of their heads, and conducted a sensory evaluation while comparing the results (half-head method). The evaluation items and scoring criteria are shown in Figure 4. The scoring results were calculated by summing the scores from all panels for each evaluation item and represented in a bar graph. The results for shampoo are shown in Figure 5, the results for conditioner in Figure 6, and the results after drying in Figure 7.

[0070] As shown in Figure 5, in the shampoos, product B (containing medium-preserved reduced starch syrup) scored significantly higher than product A (containing glycerin) in terms of lathering speed, foam volume, foam elasticity, and smoothness of the hair during rinsing. Furthermore, product B (containing medium-preserved reduced starch syrup) scored higher than product A (containing glycerin) in terms of foam fineness and fragrance. In other words, the shampoo containing medium-preserved reduced starch syrup lathered significantly faster. It also produced significantly more foam. The foam was finer. The foam had significantly stronger elasticity. The shampoo was smoother during rinsing. The fragrance was stronger.

[0071] These results revealed that the medium-saccharified reduced starch syrup has the following effects (i) to (vi) as a foaming detergent. (i) To speed up foaming. (ii) Increase the amount of foam. (iii) Break down the bubbles. (iv) To improve the elasticity of the foam. (v) Makes hair easier to run through when rinsing. (vi) To make the scent stronger.

[0072] Next, as shown in Figure 6, in the treatments, B (containing medium-preserved reduced starch syrup) scored significantly higher than A (containing glycerin) in terms of smoothness of the hair during rinsing and smoothness of wet hair. In addition, B (containing medium-preserved reduced starch syrup) scored higher than A (containing glycerin) in terms of fragrance. In other words, the treatment containing medium-preserved reduced starch syrup made the hair noticeably smoother to the touch during rinsing. Furthermore, the treatment containing medium-preserved reduced starch syrup made the hair noticeably smoother to the touch when wet. Also, the treatment containing medium-preserved reduced starch syrup had a stronger fragrance.

[0073] These results revealed that the medium-saccharified reduced starch syrup has the following effects (vii) to (ix) in hair cosmetics. (vii) Makes hair easier to run your fingers through during rinsing. (viii) Makes wet hair smooth to the touch. (ix) To intensify the scent.

[0074] Next, as shown in Figure 7, after removing moisture from the hair (after drying), the hair felt smoother to the touch after towel drying was better with product B (containing medium-saccharified reduced starch syrup) than with product A (containing glycerin). In other words, after using shampoo and conditioner containing medium-saccharified reduced starch syrup, the hair felt smoother to the touch after towel drying.

[0075] These results revealed that the medium-saccharified reduced starch syrup has the following effect (x) in hair cosmetics. (x) Makes fingers run smoothly after towel-drying.
