Description

The present invention relates to a candelilla wax dispersion composition used as a raw material for a hair treatment agent.

Candelilla wax is used as a raw material for hair treatment agents such as hair styling agents. In a hair styling agent, candelilla wax is blended as a hair styling ingredient, and it is general to use a higher fatty acid anionic surfactant together with a nonionic surfactant as a surfactant for dispersing the candelilla wax (for example, patents See paragraph 1 of document 1). When the amount of candelilla wax is increased to improve the hair styling property, the frequency of use of the higher fatty acid anionic surfactant increases. Further, in Patent Document 2, it is said that the combined use of POE(20) behenyl ether and betaine lauryl dimethylaminoacetate is superior as a surfactant for dispersing candelilla wax, rather than POE(20) behenyl ether alone ( Paragraph 0017).

JP, 2002-370937, A JP, 11-263915, A

It is as described above that there is a proposal of a surfactant suitable for dispersing candelilla wax. The type of surfactant is also selected depending on the application of the composition containing candelilla wax. Therefore, after limiting the compounding of a specific surfactant, the candelilla wax is used with a nonionic surfactant. Proposals to disperse may also be desirable.

In view of the above circumstances, the present invention does not blend a higher fatty acid-based anionic surfactant, sets the amidobetaine-type amphoteric surfactant to a predetermined amount or less, and uses the nonionic surfactant for the dispersibility of candelilla wax. The purpose of the present invention is to provide a composition having an improved composition.

As a result of earnest studies by the present inventors, it was found that the dispersibility of candelilla wax was good when a predetermined polyoxyethylene cetyl ether or polyoxyethylene polyoxypropylene cetyl ether was used. Further, in order to improve the dispersibility, it was found that it is good to control the viscosity by adjusting the compounding amount of candelilla wax. The present invention has been completed based on these findings.

That is, the candelilla wax dispersion composition according to the present invention, candelilla wax, one or more cetyl ether nonionic surfactants selected from polyoxyethylene cetyl ether and polyoxyethylene polyoxypropylene cetyl ether, In addition, water is blended, the HLB value of the cetyl ether nonionic surfactant is 11.0 or more and 16.0 or less, the higher fatty acid anionic surfactant is not blended, and the amidobetaine type amphoteric surfactant is 1 The compounding amount is less than 0.5 mass% or is not compounded, and the viscosity is 20000 mPa·s.

The ratio (B)/(A) of the compounding amount (B) of the cetyl ether type nonionic surfactant to the compounding amount (A) of the candelilla wax is preferably 0.2 or more. This ratio is particularly suitable for the dispersibility of candelilla wax.

In the candelilla wax dispersion composition according to the present invention, the volume average particle diameter of the candelilla wax is preferably 500 nm or less. The volume average particle diameter is a value obtained by measurement by a laser diffraction/scattering method.

The candelilla wax dispersion composition according to the present invention is preferably transparent or translucent. Here, "semitransparent" refers to the transparency that allows the background to be confirmed when the candelilla wax dispersion composition in a bottomed cylindrical glass container having a diameter of 4 cm is visually confirmed from the front.

Further, the candelilla wax dispersion composition according to the present invention is preferably used as a raw material to be blended with a hair treatment agent such as a hair styling agent. By using the composition according to the present invention having a good dispersibility of candelilla wax as a raw material, it becomes easy to improve the dispersibility of the candelilla wax in the hair treatment agent, and the candelilla compounded in the hair treatment agent is obtained. It is also easy to increase the amount of wax.

The candelilla wax dispersion composition according to the present invention suppresses viscosity by limiting the compounding amount of candelilla wax, and disperses candelilla wax in water with a cetyl ether-based nonionic surfactant having a predetermined HLB value range. Even if the anionic anionic surfactant is not blended and the amidobetaine-type amphoteric surfactant is blended in an amount of less than 1.5% by mass, the candelilla wax has high dispersibility.

The present invention is described below based on a candelilla wax dispersion composition according to an embodiment of the present invention (hereinafter, the “candelilla wax dispersion composition according to the present embodiment” may be referred to as the “present composition”). explain. The composition is a mixture of candelilla wax, a predetermined cetyl ether-based nonionic surfactant, and water (the content of water is, for example, 50% by mass or more).

This volume average particle diameter becomes 500 nm or less by increasing the blending amount of the cetyl ether type nonionic surfactant, and by suppressing the blending amount of candelilla wax within the particle diameter range, the appearance of the composition is transparent. Or it can be translucent. The volume average particle diameter is determined by measuring with a laser diffraction/scattering method.

(Cetyl ether nonionic surfactant)
A cetyl ether type nonionic surfactant is added to the composition in order to disperse candelilla wax. The cetyl ether nonionic surfactant is one or more selected from polyoxyethylene cetyl ether and polyoxyethylene polyoxypropylene cetyl ether, and has a predetermined HLB value (hereinafter, referred to as "Oxyethylene" may be referred to as "POE", and "polyoxyethylene polyoxypropylene" may be referred to as "POE.POP").

Examples of commercially available POE/POP cetyl ethers include “NIKKOL PBC-33”, “NIKKOL PBC-34” and “NIKKOL PBC-44” manufactured by Nikko Chemical Co., Ltd.

The HLB (Hydrophile-Lipophile Balance) value of the cetyl ether nonionic surfactant blended in the present composition is calculated by an emulsification test when the cetyl ether nonionic surfactant blended is one kind. (Details of the calculation method are given below). When two or more kinds of cetyl ether type nonionic surfactants are blended, the weighted average HLB value is taken as the HLB value of the cetyl ether type nonionic surfactant.

The calculation of the HLB value by the above emulsification test is performed as follows. That is, (1) a mass part of a cetyl ether type nonionic surfactant and b mass part of sorbitan monostearate (“NIKKOLSS-10MV” manufactured by Nikko Chemical Co., HLB value=4.7) are used, and A plurality of emulsions are obtained by the following composition and preparation method with various ratios of b and b. (2) Based on the ratio of a and b in which the particle size of oil droplets in these emulsions after being left for one day becomes the minimum , HLB value is calculated by “(10.5-4.7×b/4)4/a”.
Emulsion composition:

(8 PO), propylene glycol, 1,3-butylene glycol, glycerin, and sorbitol were used as raw materials (compounding concentrations of raw materials are shown in Tables 1 to 4 below). Then, water of about 80° C. was gradually mixed into the oil phase of about 80° C. in which the raw materials were mixed, while stirring the oil phase.
