Surfactants having polyoxyethylene chains with an addition molar number of 60 or more are surfactants having a polyoxyethylene chain as a hydrophilic group and a hydrocarbon group as a hydrophobic group, and the addition of polyoxyethylene The number of moles is above 60. The number of addition moles of polyoxyethylene is preferably 70 or more, more preferably 80 or more, still more preferably 90 or more, particularly preferably 100 or more.

Furthermore, the hydrophobic group may be bonded to either of the two ends or a single end of the polyoxyethylene chain.

When the number of added moles is above 60, it has the effect of improving the emulsification stability at various temperatures (normal temperature, high temperature, low temperature). Presumably, the reason is that a layer of polyoxyethylene chains with an added molar number of 60 or more is formed around the emulsified particles, thereby suppressing the emulsification effect of the oxidation dye that destroys the addition salt.

In addition, as a hydrophilic group, it may also have a polyoxyethylene group with an addition molar number of 60 or more in addition to the above Hydrophilic groups other than the alkene chain. Examples include ionic hydrophilic groups that are cationic or anionic, and nonionic substituents other than polyoxyethylene chains with an addition molar number of 60 or more.

In the case of having an alkyl group, since the polyoxyethylene chain is closely arranged around the emulsified particles, it has an effect of improving emulsion stability.

Furthermore, the hydrocarbon group is preferably an unsaturated hydrocarbon group. Although the unsaturated bond of the unsaturated hydrocarbon group may be a double bond or a triple bond, from the viewpoint of having excellent oxidation stability, it is preferably a double bond. By containing the unsaturated hydrocarbon group in the hydrophobic group, when stored in a low temperature environment, the crystallization of the hydrophobic group is suppressed, which has the effect of suppressing the coarsening of the emulsified particles.

The HLB value is the actual value calculated using the self-emulsification method (refer to "handbook-cosmetics/formulation materials-" Nikko Chemical Co., Ltd. (revised and issued on February 1, Showa 52)). In the actual measurement and measurement of the HLB value, the standard substance as the surfactant is sorbitan monostearate (for example, NIKKOL SS-10 manufactured by Nikko Chemical Co., Ltd.; HHLB value 4.7) and polyoxyethylene Sorbitan Monostearate (polyoxyethylene sorbitan monostearate) (for example, NIKKOL TS-10 manufactured by Nikko Chemical Co., Ltd.; HLB value 14.9) is used in combination. Liquid paraffin is used in the emulsified product. In addition, when it is considered that the liquid paraffin has changed depending on the type or lot, the measurement is performed on the spot. The liquid paraffin is emulsified with the above two surfactants, and the optimal ratio of surfactants is calculated to obtain the required HLB value (emulsified HLB value) of the liquid paraffin. The formula is shown in formula (1).

Although the required HLB value of liquid paraffin usually varies depending on the type and batch, it is about 10.1 to 10.3. Next, the HLB value of the unknown surfactant is measured by using liquid paraffin for which the required HLB value has been obtained. When the unknown surfactant is hydrophilic, it is combined with sorbitan monostearate, and when the unknown surfactant is hydrophobic, it is combined with polyoxyethylene sorbitan monostearate, And emulsify the above liquid paraffin to obtain the best ratio of stability, and take the HLB value of the unknown surfactant as x into the above formula (1) for calculation.

The upper limit is preferably 10% by mass or less, more preferably 8% by mass or less, still more preferably 6% by mass or less, and particularly preferably 5% by mass or less.

When the content of the component (B) is 0.01% by mass to 20% by mass, a layer of polyoxyethylene chains is formed around the emulsified particles, and the emulsion stability can be improved.

(System) Emulsified at a rotation speed of 200 rpm. After emulsification, after cooling to room temperature (25°C) at a rotation speed of 50 rpm, the alkali agent, oxidation dye and other ingredients are added, and the same three-stage emulsification tester as described above is used for stirring at a rotation speed of 50 rpm. The mixture was mixed to prepare an emulsified oxidation dye-containing composition.

Weigh 30g of the oxidation dye-containing composition prepared above and put it into a No. 4 standard bottle, cover the inner and outer caps, and let it stand at room temperature (25°C) for two months, according to the following standards Advance It was evaluated.

(Evaluation criteria)

○: No separation.

×: Separated by 3 mm or more from the bottom of the standard bottle.

<Evaluation method of emulsification stability at high temperature>

Weigh 30 g of the oxidation dye-containing composition prepared above and put it into a No. 4 standard bottle, cover the inner cap and outer cap, and let it stand at 60° C. for one week, and evaluated based on the following criteria.

In addition, the emulsified particle size was observed using a system polarization microscope "OLYMPUS BX51-33P-O type" (objective lens 20 times, eyepiece 10 times), and selected randomly Determine the longest diameter of 20 emulsified particles. Next, the average value of the longest diameters of 20 emulsified particles was calculated as the emulsified particle diameter.

(Evaluation criteria)

4: The emulsification state is particularly good (the separation state is less than 5 mm from the bottom of the standard bottle, and the emulsified particle size is less than 3 μm).

3: The emulsification state is good (the separation state is less than 5 mm from the bottom of the standard bottle, and the emulsified particle size is 3 μm or more but less than 4 μm).

2: The emulsified state is normal (the separated state is less than 5 mm from the bottom of the standard bottle, and the emulsified particle size is 4 μm or more but less than 5 μm).

1: Poor emulsification state (the separation state is 5 mm or more from the bottom of the standard bottle, or the emulsified particle size is 5 μm or more).

<Evaluation method of emulsification stability at low temperature>

Weigh 30g of the oxidation dye-containing composition prepared above and put it into a No. 4 standard bottle, cover the inner and outer caps, and let it stand at -10°C for 24 hours. The evaluation method of emulsification stability" evaluated the emulsification stability in the same way.

<Evaluation method of viscosity increase>

For the oxidation dye-containing composition of each example, the viscosity at the moment of preparation and the viscosity after 24 hours after preparation were measured, and the rising viscosity after 24 hours after preparation was calculated (viscosity after 24 hours after preparation-viscosity at the time of preparation) ). In addition, the measurement method of viscosity was performed using a B-type viscometer (TV-10 type manufactured by Toki Sangyo Co., Ltd.). The measurement conditions are set at 25°C for 1 minute. When the viscosity is less than 5000mPa/s, the No. 3 rotor is used for the measurement at a rotation speed of 12rpm; when the viscosity is between 5000mPa/s and 50000mPa/s, The measurement was performed using the No. 4 rotor at a rotational speed of 12 rpm; when the viscosity exceeded 50,000 mPa/s, the measurement was performed using the No. 4 rotor at a rotational speed of 6 rpm. The rising viscosity after 24 hours after manufacture was evaluated based on the following evaluation criteria.

In the evaluation of emulsification stability at room temperature, in the case of the evaluation "×", the evaluation of the increase in viscosity was not performed (the evaluation result is marked with "-".).

As the viscosity increases, the higher the evaluation, the more excellent the filling or cleansing properties are obtained due to the low viscosity at the time of manufacture. The viscosity rises during melting to obtain the more excellent dispersion stability effect.
