Description

Conditioning polymer inhibits build-up of adsorption film upon, and composition comprising the same

The present invention relates to a cumulative adsorption preventing cationic cellulose polymer and a composition comprising the same, and more particularly, to a cationic cellulose polymer which can prevent the cumulative adsorption phenomenon by optimizing molecular weight and nitrogen content.

Hair cosmetics generally have a function for hair removal that decontaminates the scalp and hair and keeps the hair clean and beautiful. In addition to the above functions, hair cosmetics are also used for additional purposes such as ease of combing, softening, smoothing or glossing the hair, lowering friction on the surface of the hair, antistatic or protecting the hair.

To impart conditioning effects to hair, hair cosmetic compositions generally comprise cationic polymers, cationic surfactants, silicones or oils, and the like. Repeated use of these chemical components may cause hair, pores or scalp problems by cumulative adsorption, which is due to skin allergies and inflammation that react with the chemical components. In particular, when the cumulative adsorption of the cationic polymer in the use component is excessive, the hair cosmetic composition not only has a disadvantage of making the hair dry, but also causes a problem of decreased elasticity, reduced smoothness and stiffness. In the case of the fabric softener used for the softness of the fiber, a cationic polymer, a cationic surfactant, silicone or oil is used. Like the hair cosmetics, if the cumulative adsorption of the cationic polymer occurs a lot, the fiber becomes stiff unlike the purpose of use. In particular, when the cationic polymer of the shampoo used for smooth conditioning feeling is adsorbed to the anionic hair and has a cumulative adsorption layer, the polymer feeling is generated and the hair becomes stiff. Avoid use of highly cationic polymers in targeted shampoos.

Cationic cellulose is adsorbed upon anionic hair when shampooed to give conditioning.Because the cumulative adsorption occurs during repeated use, the above-mentioned problems occur. Thus, it is possible to improve physical condition changes or condition hair by treating with oil. Attempts have been made to develop effective polymers. Conventional common sense is that when cationic cellulose is used, reducing the nitrogen content in cationic cellulose can lower the cationic degree and improve the adsorption of cumulative adsorption on anionic hair or fibers. Nitrogen-containing materials are present and commonly used. In addition, the nitrogen content of more than 1.8% by weight is difficult to manufacture high nitrogen content cellulose due to the limited yield according to the manufacturing process and increased steric hindrance of cellulose by the cationization reaction, there is no related material products exist It is not true.

As a result, no attempt was made to improve the cumulative adsorption of polymers by controlling the actual nitrogen content, and furthermore, no attempt was made to reduce the cumulative adsorption by increasing the degree of cationization of polymers. This is because many things happen as expected results from common sense and scientific background.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

The present inventors have made diligent research efforts to overcome the problem that the cationic cellulose adsorbing to the hair or fibers to give the conditioning function repeatedly adsorbed to the hair or fibers to form a cumulative adsorption layer and the hair or fibers stiffness, as a result of the cationic In the hair conditioner composition comprising a cellulose polymer, the cationic cellulose polymer has a molecular weight of 300,000 to 2.9 million and the nitrogen content is adjusted to 2.3 to 3.2% by weight based on the total weight of the polymer to obtain a degree of cationicity, thereby accumulating hair or fibers. It has been found that adsorption phenomenon is prevented and gives conditioning effects to hair or fibers. Accordingly, the present invention has been found that when the composition containing the cationic cellulose polymer is used for hair or fiber treatment, cumulative adsorption of the hair or fibers is prevented, so that the hair becomes soft and the fiber has a fiber softening effect. The present invention is based on this.

The present invention provides a cationic cellulose polymer capable of preventing the cumulative adsorption phenomenon during hair or fiber treatment.

The cationic cellulose polymer plays a role in imparting conditioning effects such as gloss and softness to hair or fibers.

The present invention is characterized by the development of a range of the optimum molecular weight and nitrogen content of the cationic polymer that can prevent cumulative adsorption even after repeated use and impart a conditioning effect to hair or fibers.

In the cationic cellulose polymer of the present invention, ethylene oxide (EO) or OH bonded to carbon 2 and 3 of the glucose unit in the cellulose skeleton is hydrogen bondable, and the OH site bonded to carbon 6 represents a linker. It may be a cationic cellulose polymer introduced cationic quaternary ammonium which is not capable of hydrogen bonding through. The cationic polymer may be a cationic cellulose polymer having a nitrogen content of 2.3 to 3.2 wt% and a molecular weight of 300,000 to 2.9 million based on the total weight of the polymer.

The cationic cellulose polymer of the present invention may be a quaternized ammonium salt comprising hydroxy ethyl cellulose and trimethylamine.

Alternatively, the production reaction of the cationic cellulose polymer of the present invention (this production method is referred to as reaction 1) is to prepare a quaternary ammonium salt obtained by quaternization of hydroxy ethyl cellulose with chlorohydroxypropyl trimethylamine. Can be.

Specifically, sodium hydroxide and urea are contained at a weight ratio of 7 to 9: 10 to 12: 75 to 85 (sodium hydroxide: urea: water) with respect to water as a solvent, and then 1 to 3 wt% of hydroxyethyl cellulose. It can be prepared by dissolving at a concentration of%, and then further containing a quaternary ammonium compound. More specifically, after containing sodium hydroxide and urea in a weight ratio of 7.5: 11: 81.5 (sodium hydroxide: urea: water) with respect to water as a solvent, hydroxyethyl cellulose is dissolved in a concentration of 2 wt%. Can be. The solvent of the composition helps to improve the solubility and stability of hydroxy ethyl cellulose to help improve the reforming uniformity in the reaction process. [Bi Xiong, Dissolution of cellulose in aqueous NaOH / urea solution: role of urea, Cellulose (2014) 21: 1183-1192] After the quaternary ammonium compound was added at an appropriate concentration (moles of 1 mole or more of glucose units of cellulose) ) Can be further modified to proceed by reaction according to room temperature or heating conditions.

There are three positions with modified hydroxyl groups in the glucose ring: C2, C3, C6. Of these, C6 primary alcohols generally have excellent positional selectivity for the reforming reaction because they have minimized steric hindrance. On the other hand, the difference in preference for reforming reactions between C2 and C3 is differently claimed depending on the conditions of the solvent system.

The cationic cellulose polymer of the present invention may be a polymer substituted with ethylene oxide (EO) at the α and β positions in the glucose ring. In addition, as a comparative example, the cellulose polymer was evaluated for the height of the film due to repeated adsorption using a polymer substituted with an alkyl group at the α position in the glucose ring. The structure containing the alkyl group can be prepared by adding ethylene oxide (EO) or alkylation with reference to the reference "Cationically modified cellulose-based fabric and its manufacturing method (WO 2016085099 A1)". have.

In the case of adding EO to the α and β positions in the glucose ring, gas phase polymerization using epoxide may be performed, the reactant in the chamber may be injected, and then heated and pressurized to proceed with EO addition. In the case of alkylation, the reaction may be carried out using a reactant having a halohydrin, an aldehyde or an epoxide terminal functional group so that a desired alkyl group can be added.

In an embodiment of the present invention, EO was added at the α or β position in glucose of the cationic cellulose polymer substituted with trimethyl amine, and as a comparative example, alkylation was repeated at the α position in glucose to attach a functional group. . As a result, when EO is added at the α or β position in glucose, the adsorption force is decreased due to the cation repulsion force with the polymer already adsorbed to the hair or fiber surface when the polymer is repeatedly used, and the polymer adsorbed to the hair is α and β Because of the hydrogen bonding at the site, it was washed off by hydrophilicity with water, and finally, the effect of preventing the cumulative adsorption of the cationic polymer was shown. On the other hand, the alkylated cationic cellulose polymer was found to reduce the affinity with water molecules due to the hydrophobic increase due to alkyl, thereby reducing the rinsing of the polymer by water.

Therefore, specifically, the cationic cellulose polymer of the present invention may be one in which EO is added at the α or β position in the glucose ring.

In addition, in order to increase the nitrogen content of the quaternary ammonium salt in the cationic polymer of the present invention, the addition reaction process of the quaternary ammonium compound of Reaction 1 described above is repeated while varying the amount of trimethylamine and adjusting the temperature conditions. As a result, the amount of cationization can be controlled by adjusting the nitrogen content. This was confirmed through element content analysis.

The cationic cellulose polymer may be a quaternary ammonium salt represented by Formula 1 below.

In the formula, x may be 1 to 10, preferably 1 to 5, more preferably 1 to 3. In the above formula, when n is 1, y may be 0.3 to 0.7, preferably 0.4 to 0.6, more preferably 0.45 to 0.55.

In the above formula, α and β may be ethylene oxide (EO) or OH is bonded. Specifically, any one of the α and β is combined with ethylene oxide (EO).

The cationic cellulose polymer of the present invention has a molecular weight of 300,000 to 2.9 million and a nitrogen content of 2.3 to 3.2% by weight relative to the total weight of the polymer. The cationic cellulose polymer may preferably have a molecular weight of 600,000 to 2.5 million, more preferably 70 to 1.5 million. The nitrogen content of the cationic cellulose polymer may be preferably 2.5 to 3.0% by weight, more preferably 2.7 to 2.8% by weight based on the total weight of the polymer.

When the molecular weight and the nitrogen content of the cationic cellulose polymer are within the above ranges, cumulative adsorption of the hair may be prevented and a conditioning effect may be exhibited on the hair. In one embodiment of the present invention (Examples 2 and 4 to 5), if the molecular weight of cellulose is 300,000 to 2.9 million and the nitrogen content is 2.3 to 3.2 wt%, the number of adsorption of the cationic polymer to the hair surface may be increased. The thickness of the cumulative adsorption layer was reduced and constant. This is prevented by mutual electrorepulsive force between the cationic polymer layer adsorbed on the hair and the cationic polymer to be adsorbed, while the portion adsorbed by the molecular weight has a high degree of cationicity during the rinsing process. This is because it is easily dissolved in water and washed away. In addition, it was confirmed that the adsorption thickness decreases and fluctuates when the rinsing force is increased when the cation degree and the molecular weight of the above range. On the other hand, when the cationic cellulose polymer was out of the range of molecular weight and nitrogen content (Comparative Examples 8 to 14), it was observed that the adsorption thickness was increased when the number of adsorption of the polymer was increased, that is, the cumulative adsorption occurred. , The adsorption thickness did not change even if the rinsing force was increased, and cumulative adsorption continued.

The present invention provides a cumulative adsorption preventing composition comprising the cationic cellulose polymer as an active ingredient.

In addition, the composition of the present invention can maintain the feeling of use by improving the physical state of the hair by supplying the smoothness of the hair even in repeated use.

When the composition of the present invention is used for the fiber treatment, the skin irritation given by the conventional cationic surfactant used to give the fiber softening effect can be avoided, and due to the cumulative adsorption phenomenon caused by the reuse of the polymer used for the fiber treatment on the fiber By eliminating the feeling of stiffness of the fiber can give a high satisfaction to the user.

In the present invention, "accumulation of cumulative adsorption" means that a phenomenon in which the polymer accumulates and adsorbs on the surface to be used in the repeated use of the polymer or the lamination phenomenon of the polymer can be prevented.

Production Example  One: Cationic Polymer  Produce

In the following examples and comparative examples, raw materials synthesized by the present inventors were used, and raw materials of Dow Chemical were used as necessary. In the polymerization process, the molecular weight was controlled by changing the content of ethyl cellulose, and the nitrogen content was controlled by varying the amount of trimethylamine used.

A quaternized ammonium salt was obtained by quaternization of hydroxy ethyl cellulose with chlorohydroxypropyl trimethylamine. Specifically, sodium hydroxide and urea were contained in a weight ratio of 7.5: 11: 81.5 with respect to water as a solvent, and then hydroxyethyl cellulose was dissolved at a concentration of 2 wt%. Thereafter, the quaternary ammonium compound is further contained in an appropriate excess concentration (3, 6, 9 times the number of moles of glucose ring of cellulose), and the reaction is reformed according to the temperature (25, 45, 60 ° C.) conditions. A quaternary cationic cellulose polymer of 1 was prepared.

In order to assess the adsorption state of cationic polymers, many companies, including Dow Coning, a conditioning raw material company, use a method that has a potential of tens of mV similar to hair and wool, Mica was selected as the substrate and the cationic polymer was adsorbed on the mica substrate to determine the adsorption characteristics of the polymer. There are many variables such as cuticle spacing, cuticle thickness, cuticle state, hair hydrophobicity, hair thickness, etc. for each hair, so it is not a proper evaluation method to directly adsorb cationic polymer on hair. Therefore, in this experiment, the cumulative adsorption was evaluated by selecting the mica disk as the substrate and measuring the adsorption thickness of the cationic polymer.

A 12 mm diameter mica disk (TED PELLA, Canada) was used as the adsorption target. 10 ml of polymer containing 0.5% of distilled water was used to adsorb and adsorb the polymer only to half of the mica disk, followed by washing with distilled water. The amount of polymer adsorption is determined by the electrical attraction and repulsion between the polymer and the adsorbed polymer on the mica. Since desorption proceeds due to hydrophilicity of the polymer and water, the change in the amount of polymer does not affect the adsorption amount. Thus, 0.5%, the amount of polymer typically used in shampoos, was chosen as experimental conditions.

The boundary between the adsorbed polymer layer and the mica bottom is shown by topography of the contact mode of the tip (NSC 36C, Mikro Masch, Germany) with atomic force microscopy (hereinafter AFM, Model XE-100, Korea). The thickness was evaluated as follows, and the average thickness is shown in Table 2.

Comparative Example 1 of Table 2 is a measurement of the thickness of mica dipped only in distilled water containing no polymer. As can be seen from the results of Comparative Example 1, the cumulative adsorption is due to the polymer adsorption, it can be seen that the difference in thickness comes from the polymer adsorption amount.

Comparative Example 2 is a cellulose polymer having a molecular weight of 800,000, a nitrogen content of 2.7% by weight, and in Formula 1, an α is an OH group and a β is an OH group, and Comparative Example 3 is an 800,000 molecular weight and a nitrogen content of 2.7 wt%.

Looking at the results shown in Table 2, it can be seen that the thickness adsorbed in Examples 1 to 3 is constant. Through this, it can be seen that when EO is added to the carbon-bonded units of the glucose ring unit in the cellulose skeleton, the cumulative adsorption is prevented.

In the above embodiment, it can be seen that the thickness of the adsorption layer increases when the adsorption process is repeated once to three times, which can be seen that the cationic polymer is continuously adsorbed as a single layer in the space on the negatively charged surface. . From 3 and 4 times, the adsorption thickness of the cationic polymer decreases, indicating that the anionic surface is full surface coverage due to the adsorption of the cationic polymer. When the cationic polymer is adsorbed on a single layer having a negative charge as a whole, the adsorption force is reduced by the cation repulsion force with the polymer that is already adsorbed, so that the polymer of the adsorption layer on the single layer is washed off by hydrophilicity with water in the rinsing process. It can be seen.

In Comparative Examples 2 to 6, it was observed that the adsorption thickness of the adsorption layer increases as the number of adsorption increases, but the cation repulsion between the adsorption layer and the cationic polymer is similar because the degree of cationization is similar to that of Examples 1 to 3. As a result, the rinsing force was relatively lowered in the bonding relationship with water, indicating that the cumulative adsorption phenomenon proceeded. In fact, as in Comparative Example 6, as the length of the alkyl group increases, hydrophilicity with water molecules decreases as hydrophobicity increases, resulting in cumulative adsorption.

In Comparative Example 7, as the number of adsorption increases, the thickness of the adsorption layer decreases significantly. This is a phenomenon in which the cationic polymer adsorbed in the rinsing process is washed away by combining with water molecules after the polymer is adsorbed on the hair surface. have. That is, when two or more ammonium is present in the quaternary cellulose, the rinsing force is excessively increased, thereby preventing the adsorption of the polymer.

From the results shown in Table 4, it can be seen that the thickness adsorbed in Example 2 and Examples 4 and 5 is constant. Through this, it can be confirmed that the cumulative adsorption phenomenon is prevented by adjusting the molecular weight and nitrogen content (cationic degree). Referring to Comparative Examples 8 to 14, it can be seen that the adsorption thickness increased when the number of adsorption of the polymer was increased (FIGS. 1 and 2).

It appears that the high cation degree evenly adsorbed the polymer in a certain amount when adsorbed on the surface of the anion hair. Indeed, in the examples except Examples 2 and 4 and 5, it was also found that the thickness layer of the polymer was not homogeneous. In the examples, the increase in the adsorption thickness when the adsorption was performed once or twice is likely due to the continued adsorption of the cationic polymer to the hair surface. From the third round, the thickness decreases and becomes constant, which is prevented by mutual electrorepulsive force between the cationic polymer layer adsorbed on the hair and the cationic polymer to be adsorbed, while the portion adsorbed by the molecular weight is rinsed. It appears that the polymer adsorption layer with a high degree of cation at is hydrophilic, causing it to bind with water and be washed off. As a result, the conditions of the cellulose molecular weights of 800,000 to 2.5 million and the nitrogen content of 2.7% by weight of Examples 2 and 4 to 5 seem to prevent the cumulative adsorption phenomenon.

Experimental Example 3: Change of Cumulative Adsorption Layer Thickness According to Rinsing Force

In order to confirm whether the cumulative adsorption prevention phenomenon shown in Table 4 is due to the rinsing force, the polymer adsorption was carried out as shown in Table 5 under the adsorption conditions of Comparative Examples 10 and 2, and the rinsing force was changed to confirm the adsorption thickness. It was. In Comparative Example 10 and Example 2, the molecular weight is the same as 800,000, but the nitrogen content is 1.8 and 2.7%.

The thickness change of Table 6 is represented graphically in FIG. 3 (A) shows Experiment # 4 in Experiment # 1 and FIG. 3 (B) shows Experiment # 8 in Experiment # 5. Comparing the relatively low nitrogen content (A) with the high nitrogen content (B), cumulative adsorption occurs in (A). In this case, the adsorption thickness did not change even if the rinsing force was increased. However, when cumulative adsorption was prevented as in (B), increasing the rinsing force reduced the adsorption thickness and showed a fluctuating result.

In conclusion, the cumulative adsorption prevention phenomenon of the adsorption layer is associated with high nitrogen polymer, and this effect shows that the high cationization and hydrophilic function of water play a critical role in the high nitrogen part. .

That is, it was found that the adsorption of the high nitrogen content polymer to prevent the cumulative adsorption phenomenon to prevent the cumulative adsorption phenomenon in order to use the rinsing force, that is to say that the adsorption of the high nitrogen content polymer is hydrophilic to prevent the cumulative adsorption phenomenon.

Experimental Example 4: Change of Cumulative Adsorption Layer Thickness in Polymer Adsorption According to Cationicity

Since it was confirmed that cumulative adsorption did not occur in Examples 2 and 4 and 5 of Table 3, the polymer was prepared by variously applying a degree of cationization based on the molecular weight 800,000 of the cationic polymer of Example 2 as shown in Table 7. It was. The degree of cationization is determined by the nitrogen content.

For the samples of Table 7, adsorption thickness evaluation was performed according to the degree of cationization, and the results are shown in Table 8 below.

As shown in Table 8, in the case of Comparative Example 10, Comparative Examples 15, and 16, the adsorption thickness increases with increasing number of adsorption, and thus, the degree of cationization due to the electrorepulsive force generated during the above-mentioned adsorption is not sufficient. It can be seen that a phenomenon occurs.

In Examples 6 to 7, there was no increase in the adsorption thickness according to the increase in the number of adsorption, and when the molecular weight was 800,000, it was confirmed that the cumulative adsorption phenomenon was prevented when the nitrogen content was 2.3 to 3.2 wt%. From this, it can be seen that in the state of low molecular weight, the degree of cationization can be suppressed further by the repulsive force.

However, in the case of Comparative Example 17 in which the nitrogen content that determines the degree of cation is greater than 3.2% by weight of the polymer, cumulative adsorption is prevented, but the adsorption layer decreases as the number of adsorption increases. It appeared to interfere with the amount of adsorption. It is determined that desorption occurs due to hydrophilicity with water during rinsing because the degree of cationicity is too high.

Experimental Example 5: Change in cumulative adsorption layer thickness during polymer adsorption according to polymer base

For the evaluation of the thickness of the cumulative adsorption layer according to the polymer base, the cumulative adsorption phenomenon was observed for the cellulose and other polymers described in Table 9 below, and the results are shown in Table 10 below.

In Comparative Example 18, N-Hance CCG45 of Ashland, which was guarhydroxypropyltrimonium chloride, was used. In Comparative Example 19, OaSense Care CT400 of Ashland, which is hydroxypropyl guarhydroxypropyltrimonium chloride, was used. Was used.

In Comparative Example 20 and Comparative Example 21, ethyltrimonium chloride methacrylate / propyltrimonium acrylamide / dimethylacrylamide copolymer synthetic polymer of Patent No. 10-1291693 was used.

As shown in Table 10, cumulative adsorption prevention was not observed in the non-cellulose polymer. The chemical structure of cellulose is linear ethyl cellulose, but since the guar polymer is branched structure, the desorption effect during rinsing due to hydrophilicity after the adsorption of the guar polymer is significantly lowered. In the case of synthetic polymers, it is interpreted that the repulsive force generated by adsorption differs from cellulose due to the different bonding positions of the cationic nitrogen.

Experimental Example 6: Rinsing and conditioning sensory evaluation according to the polymer

To prepare a shampoo composition in a conventional manner according to the prescription shown in Table 11.

Shampoo prescription Ingredient Weight ratio (%) Polymer 0.5 Sodium laures sulfate 8 Cocamidopropyl Bane 4.5 EDTA 4Na, function citric acid 0.1 Other ingredients 16 Purified water Balance (to 100)

Since the cellulose-based polymer has excellent solubility, the surfactant was added several times after dissolving after the addition of the polymer, and the pH was neutralized by adding EDTA.4Na and hydrous citric acid. Other ingredients added preservatives, fragrances, dispersants, viscosity regulators and pH regulators.

1 g hair tress was added to 100 mL of the 10% dilution of the shampoo and stirred at 150 rpm for 5 minutes, followed by 5 times of rinsing with 2 ml of temptation 4 ml / sec for 5 minutes. The sensory evaluation was performed to evaluate the stiffness of the treated hair, and the results are shown in Table 12 below. The experiment was conducted on 15 men and women, and the conditioning effect of hair after shampoo was evaluated based on the following evaluation criteria freshness. The results are shown in Table 12 below as average values.

Experiment # 9 was the result of treatment with anionic surfactant sodium lauryl sulfate without treatment of the polymer, and experiment # 10 was applied to the hair in which the cumulative adsorption phenomenon occurred by the shampoo treatment using the cationic cellulose polymer of Comparative Example 10. Experiment # 11 applied a polymer according to the invention (Example 2) as a conditioning polymer.

As shown in Experiment # 11 of Table 12, the cumulative adsorption preventing polymer gives freshness and can be seen to be breaking away from the existing stiff sensitivity.

Experimental Example 7: Evaluation of Friction

The conditioning effect of the cationic polymer was applied to the shampoo, and the friction was quantified by the instrument evaluation.

The shampoo composition of Table 11 was added to the Beaux hair tress by 10% by weight, bubbled for 15 seconds, rubbed for 20 seconds, rinsed in 37 ° C running tap water for 15 seconds, and the hair was wiped with a towel to remove moisture. After subtraction, the friction force was evaluated using MTT 175 Miniature Tensile Tester (DiaSTRON, GB).

The other hair is rinsed the shampooed hair for 2 minutes, dried with a dryer for 2 minutes, maintained at 25 ℃ in a constant temperature and humidity room with 50% humidity for one day, and made the moisture inside the hair constant, and then frictional force in the same temperature and humidity room Was measured and the results are shown in Table 13 below.

At this time, the hair tress was washed with anionic surfactant sodium lauryl sulfate, and then the friction value of the hair was calculated by comparing the difference with the corresponding measured value as the reference value.

Hair surface frictional force change after one use (%) Experiment Experiment # 12

In view of the results measured in Table 13, the shampoo to which the polymer proposed in the present invention shows a result of being quickly rinsed during rinsing, and has been shown to significantly reduce frictional force even after drying, thereby promoting a smooth conditioning effect. In addition, as can be seen in the above embodiments, the polymer prepared in the present invention solves the problem of cumulative adsorption in which a stiffness feel is felt by providing a cumulative adsorption preventing effect when applied as a conditioning agent, thereby providing a freshness to the hair. It was found to be a component of good hair conditioning cosmetic composition.

Subsequently, in order to confirm whether the cumulative adsorption prevention phenomenon due to repeated use is applied to the hair and at the same time to improve the stiffness caused by the cumulative prevention phenomenon, 60 times of shampoo treatment was performed to evaluate the frictional force as shown in Table 14.

Hair surface frictional force change after 60 uses (%) Experiment Experiment # 14

The decrease in the frictional force on the surface of the hair of Experiment # 14 caused by repeated washing of the shampoo according to the formulation of Table 11 can be understood as the decrease in the smoothness due to the texture of the polymer accumulated in the hair during repeated use. In Experiment # 15, the effect that the friction force does not change even after repeated cleaning and adsorption reflects the change of the polymer layer.
