Description

The present invention relates to hair treatment compositions.

  Hair treatment compositions such as hair shampoos are intended to remove stains on the hair and scalp and keep them clean, but when the hair treatment composition is formulated for product appearance and performance expression, precipitation of components, and turbidity and appearance of the appearance It is required that there is no separation. In addition, in the use of the hair treatment composition, it is easy to cause discomfort when there is a squeak when touching the hair with a hand when lathering and rinsing after being applied to the hair and scalp and rinsing, and the fingering of the hair is smooth It is required that Furthermore, after rinsing, it feels slimy when the components of the hair treatment composition adhere to the hair in a large amount, which impairs the rinse-off property, so it is required that slimming does not remain even if it takes time for rinsing.

  Heretofore, in hair treatment compositions, ionic components such as anionic surfactants, amphoteric surfactants and cationic polymers are blended. It is known that different surfactants, which have opposite charges to each other, form an insoluble complex called coacervate from the time of hair washing to the time of rinsing. As coacervate adsorbs to the hair, squeezing is alleviated during hair washing and rinsing, and the finger feels good. On the other hand, if the remaining amount to the hair is high even after rinsing, slimming remains on the hair after rinsing, or it takes time to rinse in order to remove the slimming.

  Heretofore, the following techniques have been proposed as hair treatment compositions containing different types of surfactants as described above.

  Patent Document 1 describes the use of a sulfate ester surfactant as an anionic surfactant as a hair treatment composition containing an anionic surfactant, an amphoteric surfactant, and a cationic polymer. Further, Patent Document 2 proposes a hair treatment composition in which a small amount of a phosphate ester type surfactant is blended in a base mainly composed of a sulfate type surfactant or the like. However, when a sulfate ester surfactant is used as an anionic surfactant as a main component, the amount of coacervate formed is small at the time of hair washing and rinsing, and therefore, it is easy to feel a texture. In particular, the coacervate disappears at the concentration at the time of rinse, so that it is easy to feel squeezing when rinsing the hair.

  In the example of Patent Document 2, a synthetic cationic polymer (N, N-dimethyl-3,5-methylenepiperidinium chloride) -acrylamide copolymer) is used as the cationic polymer, which is used as (poly) When used in combination with an oxyethylene alkyl ether phosphate and an amphoteric surfactant, at the concentration at the time of rinsing, the amount of coacervate formed is small, and therefore it is easy to feel a squeak.

  Patent Document 3 proposes using a copolymer containing a cationic vinyl monomer and a vinyl monomer as a cationic polymer together with a phosphoric acid ester surfactant. However, when used in combination with (poly) oxyethylene alkyl ether phosphate and an amphoteric surfactant, coacervate remains even at high dilution ratios after rinsing, so that it is likely to remain slimming, and rinsing is necessary to obtain slimming. Takes time.

  Patent Document 4 proposes using a polydimethyldiallyl ammonium salt type cationic polymer as a cationic polymer as a hair treatment composition containing an anionic surfactant, an amphoteric surfactant, and a cationic polymer. . However, the cationic polymer is prone to precipitation of the components, and clouding and separation of the appearance when the hair treatment composition is formulated. In addition, coacervate tends to disappear during rinsing. Although the example of Patent Document 4 uses an alkyl phosphate as an anionic surfactant, the alkyl phosphate causes precipitation of components when incorporated into a hair treatment composition, and causes turbidity and separation of appearance. Cheap. In addition, after rinsing, coacervate may remain in the hair in a large amount, leaving a slimy coat. Furthermore, although a large amount of amphoteric surfactant is blended to the phosphate ester surfactant, the mass ratio of the phosphate ester surfactant to the amphoteric surfactant exceeds 1: 1 and the amphoteric surfactant is Since the amount of coacervate produced is not sufficient at the concentration at the time of shampooing, the finger passing at the time of shampooing is not smooth and the feeling of use is lost when the amount of is increased.

  Patent Document 5 proposes a hair treatment composition containing an anionic surfactant, a phosphate ester surfactant, an amphoteric surfactant, and a cationic polymer. However, the synthetic cationic polymers (polyethyleneimines) used in the examples are prone to precipitation of the components, and clouding and separation of appearance, when incorporated into the hair treatment composition. In Patent Document 5, the total amount of the phosphate ester surfactant and the synthetic cationic polymer is a relatively small amount of 0.1 to 2.4% by mass, whereas the composition of the example shows the sulfate ester surfactant When the agent is blended in a large amount of 15% by mass, or in the case of incorporating an amphoteric surfactant, the agent is blended in a large amount of 15% by mass. When a sulfate ester surfactant is used as the main component as an anionic surfactant, as in Patent Documents 1 and 2, the coacervate is small at the time of rinsing and the like, so that it is easy to feel a squeak, and a phosphate ester surfactant On the other hand, when a large amount of amphoteric surfactant is blended, the amount of coacervate formed is not sufficient at the concentration at the time of hair washing as in Patent Document 4, and the finger passing at the time of hair washing is not smooth and the feeling of use is lacking.

  Patent Document 6 proposes a hair treatment composition containing a phosphate ester surfactant, an amphoteric surfactant, and a cationic polymer. However, although the example of Patent Document 6 uses an alkyl phosphate as an anionic surfactant and shows results for foaming and foam quality, the alkyl phosphate is used at the time of incorporation into the hair treatment composition. It is likely to cause precipitation of components and clouding and separation of appearance. In addition, after rinsing, coacervate may remain in the hair in a large amount, leaving a slimy coat.

In the anionic surfactant (A ′), the mass ratio of monoester salt to diester salt in potassium decyl phosphate, potassium alkyl (C _12-16 ) and potassium lauryl phosphate was 60:40.

  The cationic hydroxyethyl cellulose of a naturally derived cationic polymer (C) used Catalent HC-200 (made by Toho Chemical Industry Co., Ltd.), and cationized guar gum used JAGUAR EXCEL (made by Rhodia).

<Comparative Examples 1 to 10>
In the same manner as in Examples 1 to 27, hair treatment compositions shown in Tables 2A and 2B were prepared.

  The synthetic cationic polymer poly (N, N-dimethyl-3,5-methylenepiperidinium chloride) is Mercot 100 (manufactured by Lubrisol), (N, N-dimethyl-3,5-methylenepiperidinium chloride) -acrylamide The copolymer is Mercot 550 (manufactured by Lubrizol), DMC-DMAPAAC-DMAA copolymer (DMC: N-methacryloyloxyethyl-N, N, N-trimethylammonium chloride, DMAPAAC: N-acryloylaminopropyl-N, N, N-trimethyl ammonium chloride, DMAA: N, N-dimethyl acrylamide) used copolymer 4 of the Example in patent document 3, and polyethylenimine used EPOMIN P-1000 (made by Nippon Shokubai).

Evaluation (1) Presence or absence of turbidity or separation at the time of blending After the hair treatment composition was prepared, it was allowed to stand in a transparent container for one day at 25 ° C, and the presence or absence of turbidity or separation was visually confirmed. The case was evaluated as 〇, and the case of turbidity or separation was evaluated as x.

(2) Sensory Evaluation by Polyester Hair Bundle 12 g of polyester hair (made by Toray Monofilament Co., Ltd.) was used as a hair bundle and immersed in 350 ml of a 2% by mass aqueous solution of the hair treatment composition at 40 ° C. to wash hair. Then, it rinsed twice with 350 ml of 40 degreeC purified water. The smoothness at the time of hair washing, the smoothness at the time of rinsing, and the ease of washing out were evaluated according to the following criteria.

(3) Coacervate adhesion after rinsing and drying About 12 g of polyester hair was placed in a weighing bottle and dried at 80 ° C. for 1 hour, then cooled in a desiccator at 25 ° C. for 30 minutes and weighed (pre-treatment weight) . The hair was rinsed and rinsed in the same manner as in (2) above, dried at 80 ° C. for 1 hour, then placed in a weighing bottle and dried again at 80 ° C. for 1 hour. It was cooled at 25 ° C. for 30 minutes in a desiccator and weighed (post-treatment weight). The coacervate adhesion amount was determined by the following equation.
Coacervate adhesion amount (mg / hair bundle 1g) = weight difference of hair bundle before and after washing and rinsing treatment (mg) / weight of hair bundle before treatment (g)

(4) Average friction coefficient of hair (MIU)
About 12 g of polyester hair was used to wash and rinse in the same manner as in (2) above, and dried at 80 ° C. for 1 hour. 16 pieces of the hair are attached on a slide glass at 1 mm intervals, and after standing for 24 hours at a temperature of 25 ° C. and a humidity of 40%, an average friction coefficient is obtained using a friction tester (KES-SE, manufactured by Kato Tech Co., Ltd.) (MIU) was measured. The smaller the MIU, the smaller the surface friction of the hair and the better the smoothness.

(5) Evaluation by Repeated Treatment Using Human Hair About 10 g of a bundle of human hair (manufactured by Beaulux) was dipped in 350 ml of a 2% by mass aqueous solution of the hair treatment composition at 40 ° C. to wash the hair. It was rinsed five times with 500 ml of purified water at 40 ° C., dried at 80 ° C. for 1 hour, and then air dried at 25 ° C. This series of hair washing, rinsing and drying was repeated five times, and the average coefficient of friction (MIU) of the dried hair was measured in the same manner as in (4) above. In addition, the smoothness upon rinsing and the hair texture after drying were evaluated according to the following criteria.

(Smoothness at the time of rinse)
Evaluation criteria ◎: Very smooth and good fingering

A 2% by weight aqueous solution is evaluated with a transmittance of 25% or less as ○, more than 25% and 40% or less as Δ and more than 40% as ×, and a 0.8% by weight aqueous solution is a transmittance of less than 50% and % Or less is evaluated as Δ, and more than 98% is evaluated as x, and the 0.16% by mass aqueous solution is evaluated as transmittance of 70% or more as ○ and less than 70% as x.

  The above evaluation results are shown in Tables 1A, B, C, D and Tables 2A, B.

  From Tables 1A, B, C, D, in Examples 1 to 27 in which the mass ratio (A: B) of the component (A) to the component (B) is 1: 1 to 99: 1, turbidity at the time of blending There was no separation, and from the sensory evaluation with polyester hair tresses, it was found that the smoothness at the time of hair washing, the smoothness at the time of rinsing (relief of squeakyness) and the ease of washing out (the slimness after rinsing) were good. Furthermore, at the time of hair washing, rinsing, the transmittance (25 ° C., 600 nm) in a 2 mass% aqueous solution, 0.8 mass% aqueous solution, and 0.16 mass% aqueous solution of the hair treatment composition serving as an index of coacervate amount 40% or less, 98% or less, 70% or more, respectively. It is apparent from Examples 1 to 27 and Comparative Examples 1 to 7 that the evaluation criteria of the above-mentioned transmittance of the hair treatment composition serve as an index of smoothness at the time of hair washing, smoothness at the time of rinsing, and ease of washing out. The correlation with the coacervate adhesion amount is shown as an example of experimental results in Examples 1, 3, 4, 14 and Comparative Examples 1, 4, 6, 7.

Among the examples, phosphoric acid monoester salt represented by the formula (I), formula (II), phosphoric acid ester salt using an average addition mole number of 2 moles of oxyalkylene group of phosphoric acid diester salt is used Example 1 The permeability of 2% by weight aqueous solution and 0.8% by weight aqueous solution of the hair treatment composition is 25% or less and 50% or less at ~ 14, 16-22, 26 and 27, respectively, and the amount of coacervate at the time of hair washing and rinsing It was shown that there was more, and it was shown that the smoothness at the time of hair-washing and rinse was excellent.

  Regarding the mass ratio (A: B) of the component (A) to the component (B), Example 1 (A: B = 3: 1) and Example 5 (A: B = 5: 1) , The smoothness at the time of rinsing and the ease of washing out were the best. As compared with Examples 1 and 5, in Example 2 (A: B = 1: 1), the smoothness during hair washing has a slight decreasing tendency, and in Examples 3 and 4, the component (A) and the component (C) There is also a balance with the mass ratio with A) (A: C), and there is a slight tendency to decrease in ease of washing away, but the problem of the invention is solved by having more component A when A: B is 1: 1 or more. did. Ease of flushing is particularly good in Examples 1, 2, 5, 8 to 27 where A: B meets the minimum criteria from 1: 1 to 99: 1 and A: B is 1: 1 to 5: 1. Met.

  Example 14 used POE (2) lauryl ether potassium phosphate together with POE (3) sodium lauryl ether sulfate which is a sulfate ester surfactant as an anionic surfactant. In Example 14, the coacervate adhesion amount is smaller than Examples 1, 3 and 4 due to the early disappearance of the coacervate caused by the sulfate ester surfactant, and the smoothness at the time of rinsing as compared with Examples 1 to 13. However, by using POE (2) lauryl ether potassium phosphate together, the evaluation criteria were satisfied in solving the problems of the invention.

As for (poly) oxyalkylene alkyl or alkenyl ether phosphate (A), POE (2) lauryl ether other than potassium salt (Example 8: ammonium salt, Example 19: sodium salt, Example 20: tri The same effect was also confirmed for ethanolamine salt. The same effect was confirmed also in various kinds (Examples 8 to 12) in which the amphoteric surfactant (B) was changed from Examples 1 to 7, 13 and 14. The same effect was confirmed for the naturally derived cationic polymer (C) with multiple species (cationized guar gum of Example 13 in addition to cationized hydroxyethyl cellulose). The weight ratio of monoester salt to diester salt in POE (2) lauryl ether potassium phosphate is 30:70 (Example 15), 50:50 (Example 16), 70:30 (in addition to 60:40). The same effect is also confirmed in Example 17), 90:10 (Example 18), and in particular, in a 50: 50 to 90: 10 (Examples 16 to 18), a 0.8% by weight aqueous solution of a hair treatment composition The result is a lower permeability of and a higher amount of coacervate, which is shown to be superior in smoothness upon rinsing. The alkyl group, from Example 21, potassium POE (2) alkyl (C _{12 to 16)} ether phosphoric acid, a mixture of the length of the alkyl groups are different compounds, POE (2) alkyl (C _{10 to 18} The same effect was confirmed for the ether potassium phosphate. The same effect was also confirmed for n = 1, 5, 10 (Examples 23, 24, 25) with respect to the average added mole number n of polyoxyethylene of POE (n) lauryl ether potassium phosphate. When the average addition mole number n of the polyoxyethylene is 2 mol addition (Example 1), 1 mol addition (Example 23), 5 mol addition (Example 24), and 10 mol addition (Example 25) This is a result of lower 2 mol addition and higher coacervate content at either the 2 mass% aqueous solution or the 0.8 mass% aqueous solution of the hair treatment composition, and the 2 mol addition is at the time of hair washing and rinsing. It was shown that it is superior in the smoothness of. The pH of the hair treatment composition was confirmed to be the same in pH 5.0 (Example 26) and pH 7.0 (Example 27) other than pH 6.0.

  From Tables 2A and B, Comparative Example 1 used POE (3) sodium lauryl ether sulfate which is a sulfate ester surfactant alone as an anionic surfactant, but 0.8% by mass of the hair treatment composition It was found that the permeability in an aqueous solution did not satisfy the evaluation criteria, and the smoothness at the time of hair washing, in particular, the smoothness at the time of rinsing was not obtained, and the amount of coacervate adhesion after rinsing and drying was also small.

  Moreover, from the average friction coefficient (MIU) measurement result of polyester hair, Examples 1, 2, 5 and 11 to 14 have 0.040 to 0.044, which is a value compared with Comparative Example 1 (0.053). It was small and the smoothness of the hair was good.

  From the evaluation results by repetitive processing using human hair, the average friction coefficient (MIU) of Examples 1, 2, 5, 11 to 14 is 0.034 to 0.038, and Comparative Example 1 (0.046) In comparison, the value was small, and the smoothness of the hair was good even after repeated use with human hair. Furthermore, from the evaluation of smoothness at the time of rinsing in repeated treatment and hair aggregation after drying, in Comparative Example 1, no smoothness was observed, and it was observed that hair was entangled, Example 1, 2, 5 11 to 14, it was found that the smoothness and the cohesion of the hair were good.

  In Comparative Examples 2, 3 and 5 using various synthetic cationic polymers other than the naturally-occurring cationic polymer (C) as the cationic polymer, the transmittance of the hair treatment composition in a 0.8% by mass aqueous solution is the standard Although satisfied, the amount of coacervate was somewhat low, and the smoothness upon rinsing was insufficient. Moreover, in Comparative Examples 2 and 5, turbidity and separation were observed when the composition was blended. In Comparative Example 4, the permeability in a 0.16% by mass aqueous solution did not satisfy the standard, and as can be seen from the large amount of coacervate adhesion after rinsing and drying, slimming remained after rinsing, and washing was very bad.

  In Comparative Examples 6 and 7, the ratio of A: B exceeds 1: 1 and the amount of the amphoteric surfactant (B) is large. In Comparative Example 6, the transmittance in a 2% by mass aqueous solution does not satisfy the standard. The smoothness at the time of hair washing was inadequate. In Comparative Example 7, when 70% by mass of POE (3) sodium lauryl ether sulfate (A ′) based on the total amount of A and A ′ is used in combination, the transmittance of a 0.8% by mass aqueous solution does not satisfy the standard. The smoothness at the time of rinsing was insufficient, and the amount of coacervate adhesion after rinsing and drying was also low.

  In Comparative Examples 8, 9 and 10, potassium alkyl phosphate was used alone as the anionic surfactant (A ′), but turbidity and separation at the time of blending were observed, and in Comparative Example 9, 0.16% by mass The permeability in aqueous solution did not meet the criteria.
