Description

  The present invention relates to an oxidant-containing composition used for, for example, a hair dye, a hair bleaching / decoloring agent, or a permanent wave agent, and more specifically, an oxidant-containing composition with improved viscosity stability during storage. Related to things.

  Generally, a hair treatment agent that exhibits an effect by mixing a plurality of agents is known. Examples of such hair treatment agents include hair dyes and hair bleaching / destaining agents composed of a first agent containing an alkaline agent and a second agent containing an oxidizing agent such as hydrogen peroxide. Are known. In addition, there is known a permanent wave agent composed of a first agent containing, for example, an alkali agent and a reducing agent, and a second agent containing an oxidizing agent, for example, hydrogen peroxide.

  These preparations contain, for example, an oily component, a surfactant, and water as a base component from the viewpoint of improving the feel of hair or improving the stability of the formulation. Among these base components, a large amount of water is contained in order to suppress dryness of the preparation itself and to impart moisture retention to the hair.

  However, when a large amount of water is contained, the content of the oily component and the surfactant, which are other base components, is reduced, so that there is a problem that emulsion (viscosity) stability is lowered. In particular, the viscosity of the second agent containing an oxidizing agent such as hydrogen peroxide tends to decrease due to physical stress, for example, an action of being taken out from a container little by little and vibration during transportation. When the viscosity of the second agent is lowered, for example, there arises a problem that the target viscosity is not reached when the second agent is mixed with the first agent.

Therefore, conventionally, hair treatment compositions disclosed in Patent Documents 1 to 7 are known. Patent document 1 discloses the 2nd agent of the decoloring agent which contains glycerin monoalkyl ether and a liquid paraffin as an oil-based component in order to suppress a viscosity change. Patent Document 2 discloses a second decolorizing agent containing light liquid isoparaffin, hexyldecanol and cetanol as oil components, polyoxyethylene (10) cetyl ether as a nonionic surfactant, and stearyltrimethylammonium chloride as a cationic surfactant. Agents are disclosed (see Examples 4-7 in paragraph 0068). When the HLB value is a measured value calculated from the emulsification method, (the required HLB of the oily component) / (HLB of the nonionic surfactant) of the second agent of the decoloring agent is 0.91. Patent Document 3 discloses a second agent of a hair dye containing cetanol and microcrystalline wax as oil components, polyoxyethylene lauryl ether as a nonionic surfactant, and stearyltrimethylammonium chloride as a cationic surfactant. (See paragraph A, paragraph 0037). Polyoxyethylene lauryl ether is considered to be polyoxyethylene (2) lauryl ether from the final viscosity of the second agent. The second agent (required HLB of the oil component) / (HLB of the nonionic surfactant) of the second agent of the hair dye is 1.45 when the HLB value is an actual value calculated from the emulsification method. Patent Document 4 discloses stearyl alcohol, behenyl alcohol, octyldodecanol and liquid paraffin as oil components, polyoxyethylene (40) cetyl ether and polyoxyethylene (2) cetyl ether as nonionic surfactants, and a cationic surfactant. A second hair dye containing stearyltrimethylammonium chloride is disclosed (see Example 2 in paragraph 0043). The second agent of Example 2 contains 11.35% by mass of an oil component. Patent Documents 5 and 6 focus on the HLB of hydrophilic nonionic surfactant and lipophilic nonionic surfactant to obtain a thickening effect, and hair in which these surfactants are blended at a predetermined ratio Disclosed are treatment agents. Patent Documents 5 and 6 describe that 2.5% by mass of cetyl alcohol as an oil component, polyoxyethylene (2) cetyl ether and polyoxyethylene (40) cetyl ether as a nonionic surfactant, and a cationic surfactant. The 2nd agent of the decoloring agent containing a stearyl trimethyl ammonium chloride is disclosed (refer the Example column). Patent Document 7 discloses a general action of a higher alcohol which improves the storage stability of a preparation by improving the viscosity of the composition by using in combination with a surfactant (see paragraphs 0004 and 0014).
However, the second agent disclosed in Patent Documents 1 and 4 has a problem that the oily component is contained in a large amount, and the second agent cannot contain much water. There is also a problem that viscosity stability against physical stress is poor. The second agent disclosed in Patent Documents 2 and 3 has a problem that viscosity stability against physical stress is poor. The hair treatment agents disclosed in Patent Documents 5 and 6 have a problem that the viscosity stability is very poor in a low viscosity region of, for example, about 1,000 to 6,000 mPa · s.

As a result, a predetermined amount of oily component, nonionic surfactant, cationic surfactant, and water are contained, and the value of (required HLB of oily component) / (HLB of nonionic surfactant) is predetermined.

(A) If content of an oxidizing agent is less than 0.1 mass%, melanin may not fully be decolored and an oxidation dye may not fully be oxidized. (A) When content of an oxidizing agent exceeds 15.0 mass%, there exists a possibility that malfunctions, such as damage, may generate | occur | produce in hair.

  (B) The oil component improves the feel of hair or adjusts the viscosity of the second agent. (B) As an oil component, the specific example of the oil component in the 1st agent mentioned above is mentioned. Content of (B) oil-based component in 2nd agent is 3-10 mass%, Preferably it is 3-7 mass%, More preferably, it is 3.5-5 mass%. (B) If content of an oil-based component is less than 3 mass%, moderate viscosity cannot be provided. (B) When content of an oil-based component exceeds 10 mass%, while the water which can be mix | blended will decrease, there exists a possibility that the viscosity of a 2nd agent may become high excessively or a 2nd agent may isolate | separate.

  (C) A nonionic surfactant is adjusted to an appropriate viscosity by emulsifying the second agent. (C) As a nonionic surfactant, the specific example of the nonionic surfactant in the 1st agent mentioned above is mentioned. Content of (C) nonionic surfactant in 2nd agent becomes like this.

  In the (B) oil component and (C) nonionic surfactant contained in the second agent, the value of ((B) required HLB of oil component) / ((C) HLB of nonionic surfactant) is 0. .95 to 1.2, preferably 0.98 to 1.10, and more preferably 0.98 to 1.05. When the value of ((B) required HLB of the oil component) / ((C) HLB of the nonionic surfactant) is out of the range of 0.95 to 1.2, the viscosity stability during storage of the second agent is reduced. It cannot be improved. HLB (hydrophile-lipophile balance) is C. It is a numerical value that was conceived by Griffin and given to nonionic surfactants, and the balance of strength between the lipophilic group (alkyl group) and the hydrophilic group (ethylene oxide chain) of the nonionic surfactant is expressed numerically. It is a representation. The required HLB indicates the HLB value of the surfactant that provides the best emulsified state for the oil to be emulsified. The actual value calculated from the emulsification method is used as the HLB value (see “Handbook-Cosmetics / Formulation raw materials-” Nikko Chemicals Co., Ltd. (issued on February 1, 1977)). For the measurement of the measured HLB value, sorbitan monostearate (for example, NIKKOL SS-10 manufactured by Nikko Chemicals Co., Ltd., HLB value 4.7) and polyoxyethylene sorbitan monostearate (for example, Nikko Chemicals Co., Ltd.) were used as standard substances for the surfactant. NIKKOL TS-10 manufactured by HLB value 14.9) is used in combination. Liquid paraffin is used for the emulsion. In addition, liquid paraffin is measured every time when variation by type or lot is considered. Liquid paraffin is emulsified with the above two types of surfactants, the optimal surfactant ratio is determined, and the required HLB value of the liquid paraffin (the emulsified HLB value) is determined. The calculation formula is shown in Formula (1).

  Usually, the required HLB value of liquid paraffin is about 10.1 to 10.3 depending on the type and lot. Next, the HLB of an unknown surfactant is measured using liquid paraffin from which the required HLB value has been determined. If the unknown surfactant is hydrophilic, it is combined with sorbitan monostearate, and if the unknown surfactant is hydrophobic, it is combined with polyoxyethylene sorbitan monostearate to emulsify the liquid paraffin, A certain optimum ratio is obtained, and the HLB value of the unknown surfactant is set as x and calculated by applying the above formula (1). In addition, the required HLB value of the (B) oil component can be measured by using the oil component to be obtained instead of the liquid paraffin of the above formula (1).

(E) When the blending amount of water is out of the range of 80 to 95% by mass, the second agent cannot obtain a predetermined viscosity, and the hair moisturizing effect may be lowered.

  The viscosity of the second agent is preferably 1,000 to 6,000 mPa · s, more preferably 2,000 to 5,000 mPa · s. When the viscosity of the second agent is less than 1,000 mPa · s, it becomes difficult to mix the first agent and the second agent, or when the mixture prepared by mixing is applied to the hair, the mixture tends to sag from the hair. There is a risk of becoming. When the viscosity of the second agent exceeds 6,000 mPa · s, it is difficult to take out the second agent from the container and it may be difficult to mix the first agent and the second agent. The value of the viscosity of the second agent is a value measured using a VISCOMETER TV-10 viscometer (manufactured by Toki Sangyo Co., Ltd.) under the conditions of 25 ° C., 12 rpm rotation speed, No. 3 rotor, and 1 minute. is there. The viscosity of the second agent is appropriately adjusted by changing the contents of (B) oil component, (C) nonionic surfactant, (D) cationic surfactant, and (E) water in the second agent. Is done.

  (A) When hydrogen peroxide is added to the second agent as an oxidizing agent, the second agent is preferably a stabilizer such as ethylene glycol phenyl ether (phenoxyethanol) in order to improve the stability of hydrogen peroxide. 1-hydroxyethane-1,1-diphosphonic acid and salts thereof. Examples of the 1-hydroxyethane-1,1-diphosphonate include tetrasodium 1-hydroxyethane-1,1-diphosphonate and disodium 1-hydroxyethane-1,1-diphosphonate. The second agent may be contained in the hair dye composition and may contain components that do not inhibit the action of the components described above. For example, you may contain suitably components other than the oxidation dye and alkali agent which are contained in the 1st agent mentioned above. At that time, the content of the salt in the second agent is preferably set to 1% by mass or less. When the concentration of the salt exceeds 1% by mass, the viscosity stability of the second agent may be lowered.

  The dosage form of the second agent is not particularly limited, and specific examples include liquid, gel, and cream. Examples of the liquid include an emulsion. At the time of using the hair dye composition, a mixture is prepared by mixing the first agent and the second agent. The required amount of the mixture is then applied to the hair, attached to a comb or brush.

Moreover, the description of (A)-(E) in the "component" column in a table | surface shows the compound corresponding to each component of this-application claim. In Table 1, “(B) Mass ratio of oil component” column indicates (C) nonionic surfactant content and (D) cationic surfactant content in the oxidizing agent-containing composition. And (B) the mass ratio of the content of the oil component relative to the total. Specifically, the column “(B) Oil component mass ratio” indicates (B) Oil component content (mass%), (C) Nonionic surfactant content (mass%) and (D ) Indicates the value divided by the sum of the content (mass%) of the cationic surfactant.

<Viscosity>
After about 100 mL of the oxidant-containing composition according to each of Examples and Comparative Examples 2 to 6 and 8 was put in a 150 mL container, the viscosity value of each oxidant-containing composition was measured using a VISCOMETER TV-10 viscometer (Toki Sangyo Co., Ltd.) was used, and the measurement was performed under the conditions of 25 ° C., 12 rpm rotation speed, No. 3 rotor, and 1 minute. Since Comparative Examples 2 and 3 have high viscosity, the viscosity was measured using a No. 4 rotor. The results are shown in the “Viscosity” column. The value of viscosity at the time of this measurement is referred to as A value. In the “Viscosity Evaluation” column of Table 1, “Good” indicates that the A value is 1,000 to 6,000 mPa · s, which is the preferred viscosity range of the second agent, and “Poor” indicates that the viscosity is 1, It shows that it is out of the range of 000 to 6,000 mPa · s.

<Stress tolerance>
After about 100 mL of the oxidant-containing composition according to each of Examples and Comparative Examples 4 to 6 and 8 was put in a 150 mL container, the container was shaken up and down 10 times as a stress load, and then the viscosity was measured according to the method described above. . The results are shown in the “viscosity after stress loading” column. The viscosity at the time of measurement after stress loading is referred to as B value. And based on the A value and the B value, the value of the formula ((A−B) / A) × 100 indicating the rate (%) of decrease in viscosity was calculated. The smaller the value of this formula, the higher the viscosity stability of the oxidant-containing composition against physical stress during storage. In the “stress tolerance” column of Table 1, “10” indicates that the value of the formula is 0 or more and less than 9, and “9” indicates that the value of the formula is 9 or more and less than 11. “8” indicates that the value of the expression is 11 or more and less than 13, “7” indicates that the value of the expression is 13 or more and less than 15, and “6” indicates that the value of the expression is 15 or more and 17 "5" indicates that the value of the formula is 17 or more and less than 19, "4" indicates that the value of the formula is 19 or more and less than 21, and "3" indicates The value of the expression is 21 or more and less than 23, “2” indicates that the value of the expression is 23 or more and less than 25, and “1” indicates that the value of the expression is 25 or more. . When the rate of decrease in viscosity is 19% or more, the mixing with one agent and the operability during application become remarkable, and the practitioner can clearly experience the decrease. In addition, in the oxidizing agent containing composition which concerns on Comparative Examples 1 and 7, since the prepared oxidizing agent containing composition isolate | separated, the measurement of a viscosity is not performed. In Comparative Examples 2 and 3, since the viscosity is high and the stress load test cannot be performed, the stress tolerance is not evaluated.

  As shown in Table 1, in the oxidant-containing composition according to each example, it was found that the viscosity was 1,000 to 6,000 mPa · s, and the excellent stress resistance was exhibited. From the results regarding stress resistance, it was found that the oxidant-containing composition according to each example can improve the viscosity stability during storage. An oxidizing agent-containing composition in which ((B) required HLB of oil component) / ((C) HLB of nonionic surfactant) is in the range of about 0.98 to 1.05, according to Example 1 and Example 6. It was found that the product exhibits higher stress resistance than the oxidant-containing composition according to the other examples.

  In Comparative Examples 1 to 3 in which the content of the (B) oil component in the oxidizing agent-containing composition was outside the range of 3 to 10% by mass, the intended predetermined viscosity was not obtained. In Comparative Example 4 in which the oxidizing agent-containing composition contains an anionic surfactant instead of the (D) cationic surfactant, the stress resistance was low. In Comparative Examples 5, 6 and 8, in which ((B) required HLB of oil component) / ((C) HLB of nonionic surfactant) is out of the range of 0.95 to 1.2, the stress resistance is low. became.
