<Production method> The above-mentioned nonionic surfactant and amphoteric surfactant are dissolved in ion-exchanged water, and
Heat to <RTIgt; C </ RTI> to add the candelilla wax and stir for 1 hour with a propeller. Thereafter, the mixture is cooled on ice to obtain a composition.

<Results> As can be seen from Table 1, the cationic composition, anionic composition, nonionic composition, and amphoteric composition alone tend to cause the emulsion composition to become cloudy when used alone. And the stability is not preferable (Test Examples 1 to 4). Further, a combination of a cationic or anionic surfactant and a nonionic surfactant (Test Examples 5 and 6) or a combination of a cationic or anionic surfactant and an amphoteric surfactant (Test Examples) The same applies to 8, 9). However, when the nonionic surfactant and the amphoteric surfactant were combined (Test Example 7), the appearance of the emulsified composition became transparent, suggesting that a finely dispersed composition of wax was obtained. As a result of measurement by a dynamic light scattering method, the particle size of this fine dispersion was about 30 nm.

Investigation of Nonionic Surfactant Next, the present inventors proceeded with investigation on the optimal HLB of the nonionic surfactant. That is, the emulsified state of the nonionic surfactant was examined by changing the HLB of the nonionic surfactant based on the following composition as a basic formulation. (Blend weight ratio of amphoteric surfactant / (amphoteric surfactant + nonionic surfactant) = about 0.33) (Amphoteric surfactant / (amphoteric surfactant + nonionic surfactant) compounding weight ratio = 0.1) The results are shown in Table 2 below.

As is clear from the above table, when the weight ratio of amphoteric surfactant / (amphoteric surfactant + nonionic surfactant) is about 0.33 or 0.1, the nonionic surfactant is used. When the HLB is 6 to 15, a uniform emulsified system can be formed. In particular, when the HLB is 7 to 14, a translucent to transparent liquid phase is formed. Therefore, in the wax fine dispersion of the present invention, the HLB of the nonionic surfactant is 6 to
It is understood that in order to obtain 15, especially a translucent, transparent system, it is 7-14.

Next, the present inventors have studied the type and dispersion state of the nonionic surfactant. First, the results for the composition of Basic Formulation 1 are shown below.

It is understood that a HLB of approximately 9-11 can form a transparent liquid phase. Next, the results of the composition of Basic Formulation 2 regarding the type and dispersion state of the nonionic surfactant are shown below.

In the above table, .largecircle. Means a state in which a transparent liquid phase is formed, .DELTA. Means a translucent to uniform cream, and .times. Means separation. From the above table, it can be seen that the basic formulation 2, ie, amphoteric surfactant / (amphoteric surfactant +
When the weight ratio of each nonionic surfactant is about 0.1, when each nonionic surfactant is used alone,
It is understood that a HLB of approximately 12-13 can form a transparent liquid phase. Therefore, when the above Tables 3 and 4 are summarized, the optimum HLB value of the nonionic surfactant varies depending on the weight ratio of the surfactant, but the optimum HLB value is about 6%.
~ 15. Also, taking Table 2 into consideration, it is possible to use a plurality of nonionic surfactants in combination, and the HLB at that time depends on the weighted average.

Further, the present inventors have studied POE cholesteryl, POE glyceryl, POE hydrogenated castor oil, and the like. When these multi-chain nonionic surfactants are used alone, a transparent liquid phase is prepared. It was difficult. Of course, even with these multi-chain type nonionic surfactants, it is possible to obtain a suitable dispersion system by combining with other nonionic surfactants. Ether is preferably used.

The amphoteric surfactant and the nonionic surfactant
Correlation Next, the present inventors studied the correlation between the amphoteric surfactant and the nonionic surfactant. That is, based on the following basic formulation, an amidobetaine-type amphoteric surfactant (trade name: Levon 2000SF), a nonionic surfactant (PO
E (10) Behenyl ether) was prepared by changing the compounding ratio and compounding amount to prepare a wax dispersion system.

FIG. 1 shows the results. As is clear from the figure, POE (1) of HLB9 was used as a nonionic surfactant.
0) When behenyl ether is used, the surfactant ratio = amphoteric surfactant / (amphoteric surfactant + nonionic surfactant) exists around 0.3 at a very good ratio. Tends to increase as the amount of (amphoteric surfactant + nonionic surfactant) increases. It is to be noted that a preferable surfactant ratio is different by changing the HLB value of the nonionic surfactant. Thus, FIG. 2 shows the results when the POE (20) behenyl ether of HLB13 was used as the nonionic surfactant with the same composition as in FIG. As is clear from the figure, PO of HLB13 was used as a nonionic surfactant.
When E (20) behenyl ether is used, the surfactant ratio = amphoteric surfactant / (amphoteric surfactant + nonionic surfactant) exists around 0.1 at a very good ratio, The range of the ratio can be said to be approximately 0.04 to 0.17. Also, HLB12 is used as a nonionic surfactant.
FIG. 3 shows the results when POE (15) behenyl ether of HLB15 was used, and FIG. 4 shows the results when POE (30) behenyl ether of HLB15 was used. As can be seen from the above results, although the surfactant ratio = amphoteric surfactant / (amphoteric surfactant + nonionic surfactant) differs depending on the HLB of the nonionic surfactant, it is approximately 0.03 to 0.3. 5 is preferred. If it is less than 0.03, the contribution of the nonionic surfactant to the system becomes large, and the temperature stability is impaired. on the other hand,
If it exceeds 0.5, it becomes difficult to obtain a fine dispersion of wax.

Next, the present inventors studied safety and stability. Safety Safety was evaluated from the ovalbumin denaturation rate. <Test method> Using aqueous high performance liquid chromatography,
Egg albumin denaturation ratio 220 when a sample was added to ovalbumin pH buffered solvent so that the sample concentration became 1%.
It measured using the absorption peak of nm. [(Ho−Hs) / Ho] × 100 Ho: height of the 220 nm absorption peak of ovalbumin Hs: 22 when the sample was added to the ovalbumin buffer solvent
The height of the 0 nm absorption peak was evaluated by the following four-step evaluation.・ ・ ・: Very low skin irritation-less than 30% ovalbumin denaturation ・ ・ ・: low skin irritation-3 ovalbumin denaturation
0% or more and less than 60% △: Moderate skin irritation-Ovalbumin denaturation rate 6
0% or more and less than 80% ×: Strong skin irritation-
Egg albumin denaturation rate 80% or more

Table 5 shows the results.

From the above results, the combination of the amphoteric surfactant and the nonionic surfactant has the same level as the nonionic surfactant and has little skin irritation and high safety. Therefore, it is suggested that the fine dispersion of the wax using both surfactants has high safety.

Stability A fine dispersion of wax was prepared according to the following formulation,
Stability at 1 ° C. for one week was evaluated. Table 6 shows the results. <Basic prescription 4> Candelilla wax 10% Surfactant About 10 to 20% Deionized water Remainder

As is apparent from Table 6 above, the nonionic surfactant alone and the surfactant ratio (defined above) were 0.1%.
If it is less than 03, the stability over time is impaired. On the other hand, the stability was good with the combination of the amphoteric surfactant and the nonionic surfactant in the preferred surfactant ratio.

Although there are molecular structures of copolymers (copolymers), that is, block polymers and random polymers (including sandwich types), research has shown that the terminal groups of the block polymers are more water-soluble, This is probably because the random polymer has more oil solubility. The significance of celluloid erosion did not change. In addition, a study was also conducted on a phosphoric ester of a polyether compound obtained by addition-polymerizing EO to a main chain obtained by addition-polymerizing PO to a polyhydric alcohol nucleus in an amount of 20 to 90 mol, and used in the present invention. Compared with the polyether compound, it was confirmed that hair styling retention and usability (stickiness of hands) were not preferable.

Further, as one preferable group of polyether compounds, (II) a polyether compound obtained by addition-polymerizing 20 to 100 mol of propylene oxide to polyglycerin of triglycerin or more, or propylene oxide 4
A polyether compound obtained by addition polymerization of 0 to 120 moles and 1 to 20 moles of ethylene oxide is exemplified.

In the compound group (II), polyglycerin: a polyglycerin mixture of triglycerin or more, having 5 or more terminal hydroxyl groups, is polymerized by addition of 20 to 100 mol of PO, preferably 4
It is a polyether compound obtained by addition polymerization of 0 to 80 mol or a compound obtained by addition polymerization of 40 to 120 mol of PO and 1 to 20 mol of EO, preferably addition polymerization of 3 to 10 mol of EO. Of these, particularly preferred are those obtained by addition polymerization of 50 to 90 mol of propylene oxide to a decaglycerin mother nucleus.

Addition of PO at a low molar level to polyglycerin has a strong celluloid erosion property, and addition of 20 mol or more of PO can eliminate celluloid erosion property and moderate viscosity. ~ 15
It shows a viscosity of 00 mPa · S, and even when PO is added up to 100 mol, the polar groups having 5 to 8 terminal hydroxyl groups of polyglycerin work effectively, the water dispersibility is good, and hand stains To obtain a compound characterized by being easily washed off. When PO is added to polyglycerin by the above-mentioned optimum PO, the compound becomes oily and has poor water dispersibility, but by further adding 1 to 20 mol of EO,
A compound having excellent hair styling properties, no celluloid erosion, and good water solubility can be obtained. The same applies to the case where 1 to 20 moles of EO is added to polyglycerin, and then PO is polymerized in an amount equal to or more than the above-mentioned optimum addition mole number. Also,
Studies were also conducted on the phosphate esters of these polyether compounds, but compared with the polyether compounds used in the present invention, hair styling retention and fat solubility (stickiness of hands)
Was unfavorable.

The polyether compound (II) has a copolymer (copolymer) molecular structure, that is, a block polymer or a random polymer (including a sandwich type). Since the terminal group of the coalesced was more water-soluble, the hair washing property was superior to the random polymer. This is presumably because the random polymer has more oil solubility. The significance of celluloid erosion did not change. In addition, a study was also conducted on a phosphoric ester of a polyether compound obtained by addition-polymerizing EO to a main chain obtained by addition-polymerizing PO to a polyhydric alcohol nucleus in an amount of 20 to 90 mol, and used in the present invention. Compared with polyether compounds, hair styling retention,
It was confirmed that the usability (stickiness of the hand) was not favorable.

For example, in a N ₂ gas, a polyhydric alcohol is mixed with particulate caustic soda, and PO is reacted at a reaction temperature of 100 to 120 ° C.
Add slowly under an internal pressure of 5-7 kg / cm ² G, then add E
If O is added, a polyhydric alcohol propylene oxide / ethylene oxide addition polymer is obtained. Such polyether compounds are described, for example, in JP-B-55-10567.

The remainder of (5) was added to obtain an emulsion composition. <Production method of set lotion> The above two compositions and (3) were mixed in the proportions in the above table to obtain a set lotion.

From the above results, it can be seen that in Test Example 12 lacking the wax composition, a moderate feeling of use was obtained in terms of the lack of stickiness of the hand, the ease of passing through the hand, and the smoothness. In comparison with Test Example 11, the hair styling power was far inferior. On the other hand, in Test Example 10 in which the fine dispersion of the wax of the present invention and the polyhydric alcohol core were mixed with a polyether compound obtained by addition polymerization of propylene oxide and / or ethylene oxide, Test Example 10 showed no stickiness. It can be seen that the ease of passing through the hand, smoothness, and hair styling are all improved, and the improvement effect is maintained for 6 hours. In addition, it can be seen that the effect of improving hair styling can be maintained up to 12 hours later.

The oil-in-water type hair cosmetic of the present invention is prepared by separately preparing an emulsion composition containing a fine dispersion of wax and a polyether compound obtained by addition polymerization of propylene oxide and / or ethylene oxide to a polyhydric alcohol nucleus. After that, mix them. Thus, a composition prepared according to the present invention, which had substantially the same composition as the composition of Test Example 10 described above and was not divided into wax parts and emulsified parts, was used as Test Example 13. The difference between the oil-in-water hair cosmetic of the present invention and Test Example 13 is that, in the present invention, emulsion particles and wax dispersed particles of a polyether compound obtained by addition polymerization of propylene oxide and / or ethylene oxide to a polyhydric alcohol nucleus are Although present separately, in the composition of Test Example 13, they both form the same dispersed particles.
