Description

Oxidizing agent-containing composition

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, hair treatment agents that exhibit an effect by mixing a plurality of agents are 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 base components 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 and 2 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 pays attention to HLB of a hydrophilic nonionic surfactant and a lipophilic nonionic surfactant to obtain a thickening effect, and a hair treatment agent in which these surfactants are blended at a predetermined ratio. Is disclosed.

However, the second agent disclosed in Patent Document 1 contains a large amount of liquid paraffin as an oil component, and there is a problem that the second agent cannot contain much water. There is also a problem that viscosity stability against physical stress is poor. The hair treatment agent disclosed in Patent Document 2 has 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.

The content of the oxidizing agent in the second agent is preferably 0.1 to 15.0% by mass, more preferably 2.0 to 9.0% by mass, and most preferably 3.0 to 6. 0% by mass. When the content of the oxidizing agent is less than 0.1% by mass, melanin may not be sufficiently decolored and the oxidation dye may not be sufficiently oxidized. When the content of the oxidizing agent exceeds 15.0% by mass, there is a risk that defects such as damage occur on the hair.

Oily component improves hair feel and adjusts the viscosity of the second agent. As an oil component, the specific example of the oil component in the 1st agent mentioned above is mentioned. The content of the oil component in the second agent is 3 to 10% by mass, preferably 3 to 7% by mass, and more preferably 3.5 to 5% by mass. If the content of the oil component is less than 3% by mass, an appropriate viscosity cannot be imparted. When the content of the oil component exceeds 10% by mass, the water that can be blended is decreased, and the viscosity of the second agent may be excessively increased or the second agent may be separated.

The nonionic surfactant is adjusted to an appropriate viscosity by emulsifying the second agent. As a nonionic surfactant, the specific example of the nonionic surfactant in the 1st agent mentioned above is mentioned. The content of the nonionic surfactant in the second agent is preferably 0.01 to 2% by mass, more preferably 0.1 to 1% by mass, and further preferably 0.3 to 0.8%. % By mass. When the content of the nonionic surfactant is less than 0.01% by mass, the second agent cannot be sufficiently emulsified and the second agent may be separated. When content of nonionic surfactant exceeds 2 mass%, there exists a possibility that the viscosity of a 2nd agent may rise or isolate | separate.

The cationic surfactant can emulsify the second agent, and further prevents a decrease in viscosity against physical stress. As a cationic surfactant, the specific example of the cationic surfactant in the 1st agent mentioned above is mentioned. The content of the cationic surfactant in the second agent is preferably 0.01 to 2% by mass, more preferably 0.1 to 1% by mass, and still more preferably 0.2 to 0.5%. % By mass. When the content of the cationic surfactant is less than 0.01% by mass, the effect of preventing the decrease in the viscosity of the second agent cannot be sufficiently improved. If the content of the cationic surfactant exceeds 2% by mass, the viscosity of the second agent may increase or be separated.

The mass ratio of the content of the oil component to the total content of the nonionic surfactant and the cationic surfactant in the second agent is preferably 3.5 to 10, more preferably 4 to 7, more preferably 4 to 6. By setting the mass ratio of the content of the oil component in the range of 3.5 to 10, it is possible to more reliably prevent the viscosity from being reduced by physical stress.

In the oily component and the nonionic surfactant contained in the second agent, the value of (required HLB of the oily component) / (HLB of the nonionic surfactant) is defined as 0.9 to 1.2, preferably It is 0.98 to 1.10, more preferably 0.98 to 1.05. HLB (hydrophile-lipophile balance) is calculated from the Griffin equation. The required HLB indicates the HLB value of the surfactant that provides the best emulsified state for the oil to be emulsified. If the value of (required HLB of oil component) / (HLB of nonionic surfactant) is outside the range of 0.9 to 1.2, the viscosity stability during storage of the second agent cannot be improved. When a plurality of substances are used as the oil component, the average value of the required HLB of those substances is used as the “required HLB of the oil component”. Similarly, when a plurality of substances are used as the nonionic surfactant, the average value of HLB of those substances is used as “HLB of nonionic surfactant”.

Water acts as a solubilizer for each component, and maintains the viscosity of the second agent at a predetermined value together with the oil component, nonionic surfactant, and cationic surfactant. Water also prevents the drug from drying by moisturizing the hair or imparting moisture to the hair. The water content in the second agent is preferably 80 to 95% by mass, more preferably 85 to 95% by mass. If the 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 viscosity value 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 the oil component, nonionic surfactant, cationic surfactant, and water in the second agent.

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), 1- Contains hydroxyethane-1,1-diphosphonic acid and its salts. Examples of 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.
