Description

Hair cosmetic composition

Technical Field

The present invention relates to a hair cosmetic composition.

Background

Hair cosmetic compositions containing cationic polymers and anionic polymers are known.

For example, japanese patent application laid-open No. 53-139734 (patent document 1) describes the following: by using a keratin substance treatment composition characterized in that it comprises, in a solvent medium, at least one anionic polymer and at least one cationic polymer, it is possible to immobilize the anionic polymer on keratin substances which may include, in particular, hair, skin or nails. The reason for obtaining the above effect is considered to be related to a complex (complex) formed by the interaction between the polymers of the anionic polymer and the cationic polymer.

Japanese patent laid-open publication No. 2005-166333 (patent document 2) describes the following: a hair cosmetic comprising: a cationic polymer having a charge density in a specific range; and an anionic polymer which contains 80 to 100 mass% of a specific anionic structural unit and has a weight average molecular weight of 4,000 to 80,000; the hair cosmetic can improve the touch and appearance of damaged hair, and can maintain these effects even if repeatedly shampooing.

Disclosure of Invention

The present invention discloses the following.

A hair cosmetic composition comprising:

Component (A): more than 1 polymer selected from cationic polymers and amphoteric polymers;

component (B): an anionic polymer;

component (C): a nonionic compound of 1 or more selected from the group consisting of polyglycerol and its derivatives, sorbitan fatty acid esters having an HLB of 1 to 5, polyoxyethylene sorbitan fatty acid esters having an HLB of 1 to 5, and glycerol fatty acid esters having an HLB of 1 to 5;

Component (D): a cationic surfactant; and

Component (E): higher alcohols;

The total content of the component (A) and the component (B) is less than 1.0 mass%.

Detailed Description

As described in patent document 1, it is known that a complex formed from a cationic polymer and an anionic polymer (hereinafter, also referred to as "polyion complex") is used as a composition for treating keratin materials, but there is room for improvement in terms of improving the performance when used as a hair cosmetic composition.

For example, a hair conditioner which is one of hair cosmetic compositions is required to have excellent moisture resistance, while having a good feel when applied to hair, and the treated hair is not rough even under high humidity conditions. In particular, the prior art of patent documents 1 and 2 does not obtain a particular effect in suppressing the rough hair under high humidity conditions.

Further, as the composition containing the polyion complex, there is a product in the form of an oil-in-water or water-in-oil emulsion composition, but these emulsion compositions have a problem that the stability with time needs to be improved. In particular, in hair cosmetic compositions, cationic surfactants, higher alcohols, and the like may be blended to improve the feel of the treated hair. However, if these components are formulated into an emulsified composition containing a polyion complex, the stability tends to be lowered.

The present invention has an object to provide a hair cosmetic composition which has a good feel when applied to hair, can suppress rough hair under high humidity conditions, and has high stability.

The inventors found that: the hair cosmetic composition containing 1 or more polymers selected from cationic polymers and amphoteric polymers, anionic polymers, specific nonionic compounds, cationic surfactants, and higher alcohols, wherein the total content of the 2 polymers is less than a specific value, can solve the above problems.

The present invention provides a hair cosmetic composition which has a good feel when applied to hair, can suppress rough hair under high humidity conditions, and has high stability.

[ Hair cosmetic composition ]

The hair cosmetic composition of the present invention (hereinafter, also simply referred to as "composition of the present invention") contains:

component (B): an anionic polymer;

Component (D): a cationic surfactant; and

Component (E): higher alcohols;

With the above composition, the hair cosmetic composition of the present invention has a good feel when applied to hair, can suppress rough hair under high humidity conditions, and has high stability.

In the present specification, "component X is included in the formulation of component X.

The reason why the hair cosmetic composition of the present invention exerts the above-described effects is not clear, and the following possibilities are considered.

The hair cosmetic composition of the present invention comprises a polyion complex formed from component (A) and component (B).

The polyion complex is an aggregate formed by the chemical electrostatic interaction of the component (a) and the component (B). The polyion complex is hardly soluble in water, and a hydrophobic coating film can be formed by applying a hair cosmetic composition containing the polyion complex to hair. It is considered that the formation of the hydrophobic coating improves the touch feeling when applied to hair and the moisture resistance.

In addition, it is considered that: by setting the total content of the component (a) and the component (B) in the hair cosmetic composition to less than 1.0 mass%, stability is good even in the form of an emulsified composition containing a polyion complex.

Further, it is considered that: the component (C) contained in the hair cosmetic composition penetrates into the hair to exert a hair-modifying effect, thereby further improving the feel when applied to the hair and suppressing the rough hair under high humidity conditions. In addition, depending on the kind of the nonionic compound, the following may be the case: if blended into a hair cosmetic composition, the stability of the emulsion in the composition is lowered, and the dispersion state of the emulsion is deteriorated due to a decrease in viscosity or the like. However, it is considered that: in the present invention, the use of a specific nonionic compound as the component (C) can maintain the stability of the composition without deteriorating the dispersion state of the emulsion. In addition, it is considered that: by containing the component (D) and the component (E), the hair cosmetic composition further improves the feel when applied to hair.

The form of the hair cosmetic composition of the present invention is preferably an emulsion composition, and more preferably an oil-in-water emulsion composition from the viewpoint of stability of the composition and improvement of feel in use.

Examples of the product form of the hair cosmetic composition include shampoo, conditioner (HAIR RINSE), hair conditioner (hair conditioner), hair care agent (HAIR TREATMENT) (including leave-in hair), and hair styling agent. Among these, from the viewpoint of effectiveness of the effects of the present invention, a hair conditioner, a hair care agent, or a hair styling agent is preferable.

Examples

The present invention will be described below by way of examples, but the present invention is not limited to the scope of the examples. In the examples, the measurement and evaluation were performed by the following methods.

(Determination of pH value)

To each example of the hair cosmetic composition (conditioner) was added water to prepare a 5% aqueous solution, and the pH value at 25℃was measured using a pH meter (manufactured by horiba manufacturing Co., ltd., F-51). The pH values were all 3.4.

(Emulsion state)

The hair conditioner 1g of each example was applied dropwise to a black pad layer made of plastic, and the resultant was drawn 10 times with a finger, and the appearance and touch were evaluated based on the following criteria.

A: the agglomerated particles were not visually observed, and the touch was smooth when drawn with a finger.

B: the agglomerated particles were not visually observed, but the touch was rough when drawn with a finger.

C: agglomerated particles were visually observed, and the touch was rough when drawn with a finger.

D: and (5) separating.

(Storage stability)

The storage stability of each example of the conditioner was evaluated by a cycle test.

The hair conditioner of each example was subjected to a cycle test in which the conditioner was stored for 2 weeks under an environment in which the temperature was changed in the range of 40℃to-28 ℃. The daily temperature cycle is set to a cycle in which the temperature difference Δt=40 ℃ is performed 4 times daily. The hair conditioner after storage was visually inspected for separation, and in the table, the stable and non-separable person was denoted as "a", and the separable person was denoted as "D".

(Touch feeling at application time)

A bleaching agent (a preparation prepared by mixing 7mL of "KAO Bubble Hair Bleach L" (1 solution) and 14mL of "KAO Bubble Hair Color d" (2 solution)) was applied to Japanese hair bundles having a length of 30cm and a mass of 20g, and the hair bundles were left standing for 20 minutes and then rinsed with warm water at 35 to 40 ℃. The above treatment was repeated 4 times to prepare a hair bundle for evaluation of Japanese damaged hair.

1ML of each example of the conditioner was applied to the above-described evaluation hair tresses, and the hair tresses were hand-fused. The touch at this time was evaluated by 5 professional functional inspectors on a scale of 5 according to the following criteria, and the average value thereof was used as an evaluation result.

5: Is extremely smooth.

4: And (3) smoothness.

3: Slightly smooth.

2: Smoothness is the same as in the case of using a general hair conditioner having the following composition.

1: The sense of presence immediately disappears and is not smooth.

[ Composition of ordinary Hair conditioner ]

(﹡ 1) "FARMIN DM-E80" manufactured by Kagaku corporation, the amount of the active ingredient was 90% by mass.

(﹡ 2) "KALCOL 8098" manufactured by Kagaku corporation, the amount of the active ingredient was 100% by mass.

(﹡) 3) PURAC Thailand Ltd.

(Moisture resistance of treated Hair)

1ML of each example of the conditioner was applied to a strand of damaged Japanese hair evaluation hair prepared by the above method, and the strand was fused for 30 seconds. After being left in this state for 1 minute, the glass was rinsed with running water for 30 seconds and dried by a blower until completely dried.

The dried hair was fringed Shu Lazhi times using a flat iron (AHI-938 manufactured by sanmu industries, inc.) set at 160 c, while the hair tress was combed, and the hair tress just straightened was photographed. Next, the straightened hair was hung and left standing for 30 minutes at 35℃under a high humidity atmosphere of 80% RH, and photographed again. The width of the hair bundle at 23.5cm from the root of the hair bundle was measured in 2 photographs, and the change in the width of the hair bundle immediately after straightening and after storage under high humidity was calculated by the following formula.

Hair strand width change value= (hair strand width after preservation under high humidity)/(hair strand width immediately after straightening)

When the above value exceeds 1.3, the appearance is seemingly rough, and therefore it is judged that the moisture resistance is low.

Example 1 (preparation and evaluation of conditioner)

Using the ingredients shown in Table 1, hair conditioners were prepared in the following order.

Into a 500mL beaker were charged 1.52g of the polyquaternium-6 solution as component (A), 3g of lactic acid (90 mass%) and 419.7g of water, and the mixture was heated and stirred at 80℃using a stirring apparatus (a mechanical stirrer having 2 propeller blades). After confirming that the solution was homogeneous, 0.37g of sodium polyacrylate as the component (B) was added and mixed to obtain a mixture A as a homogeneous suspension (step (1)).

Next, a hair cosmetic composition (conditioner) was prepared in the following order.

The oil phase component was added to the above mixture A, and heated and stirred at 75℃for 10 minutes. After stirring for 10 minutes, the heating was stopped and air cooling (preparation of emulsion (I)) was started.

Next, an oil (10.0 g of polydimethylsiloxane and 5.0g of lanolin fatty acid) as component (I) described in table 1 and 3.50g (90 mass%) of the rest of lactic acid were added, and the mixture was cooled while stirring until the liquid temperature became 40 ℃ or lower, thereby obtaining 500mL of hair conditioner (step (2-1)).

The obtained conditioner was used for evaluation in the above-described manner. The results are shown in table 1. The blending amount described in the table of this example is the blending amount (mass%) of each component in terms of wet weight, and the "effective content" described in the table of this example is the content or blending amount (mass%) of each component in terms of the amount of the effective component.
