Preparation of Fine Dispersion First, the present inventors conducted the following tests to prepare a fine dispersion composition of wax.

[0025]

<Production method> The above-mentioned nonionic surfactant and amphoteric surfactant are dissolved in ion-exchanged water.
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 is apparent from Table 1, the cationic surfactant, anionic surfactant, nonionic surfactant and amphoteric surfactant alone tend to cause the emulsified 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.

Examination of Nonionic Surfactant Next, the present inventors proceeded with examination of 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.

[0029]

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 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.

[0032]

[Table 3] {HLB: 5 6 7 8 9 10 11} ─────────────────────────────────── POE linear fatty acid C12 (lauryl) △ ○ ○ n = 3 n = 5 n = 7 C16 (cetyl) △ ○ ○ n = 5 n = 7 n = 9 C18 (stearyl) △ ○ △ n = 6 n = 8 n = 10 C18 (oleyl) △ ○ △ n = 6 n = 8 n = 10 C20 (aralkyl) × ○ n = 3 n = 10 C22 (hexenyl) × ○ n = 5 n = 10 ─────────────────────── ───────────── POE branched fatty acid C18 (isostearyl) △ ○ n = 5 n = 10 C20 (octyl todecyl) ○ n = 10 C24 (decyl tetradecyl) △ ○ n = 10 n = 15 ──────────────────────────────────── (n: number of moles of POE added)

In the above table, ○ means a state in which a transparent liquid phase is formed, 形成 means a translucent or uniform cream, and × means separation. From the above table, it can be seen that the basic formulation 1, namely, amphoteric surfactant / (amphoteric surfactant +
When the weight ratio of the nonionic surfactant is about 0.33, when each nonionic surfactant is used alone,
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.

[0034]

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 and nonionic surfactants
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 should 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, HLB1 is used as a nonionic surfactant.
When the POE (20) behenyl ether of No. 3 is used, the ratio of surfactants = amphoteric surfactant / (amphoteric surfactant + nonionic surfactant) exists at a very good ratio near 0.1. However, the range of the ratio is generally 0.04 to
0.17.

HLB is used as a nonionic surfactant.
FIG. 3 shows the results when using 12 POE (15) behenyl ethers, and FIG. 4 shows the results when using POE (30) behenyl ethers of HLB15. 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.

[Table 5] 評 価 Evaluation of surfactantsナ ト リ ウ ム Sodium dodecyl sulfate (anionic) △ Lauryldimethylammonium chloride (cationic) × POE (20) Behenyl ether (non-ionic) ◎ Levon 2000SF (amphoteric) ○ Sodium dodecyl sulfate + POE (20) behenyl ether ○ (1: 1) Levon 2000SF + POE (20) behenyl ether ◎ (1: 1) ───── ─────────────────────────────── (Levon 2000SF; manufactured by Sanyo Chemical Co., Ltd., aminobetaine-type amphoteric surfactant)

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.
